Estudio de caso: revascularización de paciente con enfoque en el proceso de atención de enfermería / Case study: Patient revascularization with focus on the nursing care process

Introducción: la cardiopatía isquémica fue la primera causa de muerte en México en el año 2020. Su prevalencia aumenta con la edad y es superior en los hombres que en las mujeres; se presenta mayormente en forma de infarto en edades entre 45 y 94 años. Objetivo: describir el caso de un paciente sometido a revascularización aorto-coronaria por cardiopatía isquémica con enfoque del proceso de atención de enfermería (PAE). Metodología: estudio de caso observacional y descriptivo con aplicación del PAE en el perioperatorio de un hombre de 50 años con cardiopatía isquémica crónica, enfermedad multivascular e hipertensión sistémica controlada de 6 años desde que inició, en un hospital público de tercer nivel en Mérida, Yucatán, México. Resultados: se demostró que si se aplica el PAE hay menor riesgo de shock hipovolémico ocasionado por sangrado activo y disminución de riesgo de infección del sitio de herida quirúrgica, evidenciado por el procedimiento quirúrgico extenso. Conclusiones: la metodología del PAE como método científico facilita innovaciones dentro de los cuidados enfermeros, además de las diferentes alternativas en las acciones a seguir para el tratamiento del paciente quirúrgico cardiovascular. También proporciona un método informativo para la atención de cuidados, desarrolla una autonomía para la enfermería y fomenta la consideración como profesional de salud.

Introduction: Ischemic heart disease was the leading cause of death in Mexico in 2020. Its prevalence increases with age and it is higher in men than in women; it is presented mostly as a heart attack between the ages of 45 and 94 years. Objective: To describe the case of a patient undergoing aorto-coronary revascularization for ischemic heart disease with a nursing care process (NCP) approach. Methodology: Observational and descriptive case study with application of NCP in the perioperative period of a 50-year-old man with chronic ischemic heart disease, multivessel disease and controlled systemic hypertension of 6 years since its onset, in a third level public hospital in Merida, Yucatan, Mexico. Results: It was demonstrated that by applying NCP there is a lower risk of hypovolemic shock caused by active bleeding and decreased risk of surgical wound site infection, evidenced by the extensive surgical procedure. Conclusions: The NCP methodology as a scientific method facilitates innovations within nursing care, in addition to the different alternatives in the actions to follow for the treatment of the cardiovascular surgical patient. It also provides an informative method for care, develops autonomy for nursing and promotes consideration as a health professional.

Diferenças entre os Sexos no Infarto Agudo do Miocárdio com Supradesnivelamento do Segmento ST - Análise Retrospectiva de um Único Centro / ST-Segment Elevation Myocardial Infarction Differences between Genders - A Single Center Retrospective Analysis

Resumo Fundamento Embora os resultados em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST) submetidos a intervenções coronárias percutâneas (ICP) primárias tenham melhorado, as mulheres apresentam maior mortalidade. Objetivos: Avaliar as diferenças de gênero na apresentação, manejo e mortalidade hospitalar, em 30 dias, 6 meses e 1 ano após IAMCSST. Métodos Coletamos retrospectivamente dados de 809 pacientes consecutivos tratados com ICP primária e comparamos mulheres versus homens no banco de dados de cardiologia de intervenção local. O nível de significância utilizado foi p<0,05. Resultados As mulheres eram mais velhas que os homens (69,1±14,6 vs. 58,5±12,7 anos; p<0,001) com maior prevalência de idade acima de 75 anos (36,7% vs. 11,7%; p<0,001), diabetes (30,6% vs. 18,5%; p=0,001), hipertensão (60,5% vs. 45,9%; p=0,001), doença renal crônica (3,4% vs. 0,6%; p= 0,010) e acidente vascular cerebral isquêmico agudo (6,8% vs. 3,0%; p=0,021). Na apresentação, as mulheres apresentavam mais sintomas atípicos, menos dor torácica (p=0,014) e estavam mais frequentemente em choque cardiogênico (p=0,011)). As mulheres tinham mais tempo até a reperfusão (p=0,001) e eram menos propensas a receber terapia médica ideal (p<0,05). A mortalidade intra-hospitalar (p=0,001), em 30 dias (p<0,001), 6 meses (p<0,001) e 1 ano (16,4% vs. p<0,001) foi maior nas mulheres. A análise multivariada identificou idade acima de 75 anos (HR=4,25; IC 95%[1,67-10,77];p=0,002), classe Killip II (HR=8,80; IC 95%[2,72-28,41];p<0,001), III (HR=5,88; IC95% [0,99-34,80]; p=0,051) e IV (HR=9,60; IC 95%[1,86-48,59];p=0,007), Lesão Renal Aguda (HR=2,47; IC 95% [1,00-6,13];p=0,051) e dias de hospitalização (HR=1,04; IC 95%[1,01-1,08];p=0,030), mas não o sexo feminino (HR=0,83; IC95% [0,33-2,10];p=0,690) como fatores prognósticos independentes de mortalidade. Conclusões Comparadas aos homens, as mulheres com IAMCSST submetidas à ICP primária apresentam maiores taxas de mortalidade. Mulheres hospitalizadas por IAMCSST têm pior perfil de risco, são tratadas com maior tempo de reperfusão relacionado a atrasos do sistema e têm menor probabilidade de receber a terapia recomendada. O sexo feminino não foi fator prognóstico independente para mortalidade na população estudada.

Abstract Background Although outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary interventions (PCI) have improved, women show higher mortality. Objectives To assess gender differences in presentation, management and in-hospital mortality, at 30-days, 6-months and 1-year after STEMI. Methods We retrospectively collected data from 809 consecutive patients treated with primary PCI and compared the females versus males at the local intervention cardiology database. The level of significance used was p<0.05. Results Women were older than man (69,1±14,6 vs. 58,5±12,7 years; p<.001) with higher prevalence of age over 75 years (36.7% vs. 11.7%; p<.001), diabetes (30,6% vs. 18,5%; p=.001), hypertension (60.5% vs. 45.9%; p=.001), chronic kidney disease (3.4% vs. 0.6%; p=.010) and acute ischemic stroke (6.8% vs. 3.0%; p=.021). At presentation, women had more atypical symptoms, less chest pain (p=.014) and were more frequently in cardiogenic shock (p=.011)). Women had longer time until reperfusion (p=.001) and were less likely to receive optimal medical therapy (p<0.05). In-hospital mortality (p=.001), at 30-days (p<.001), 6-months (p<.001) and 1-year (16.4% vs. p<.001) was higher in women. The multivariate analysis identified age over 75 years (HR=4.25; 95% CI[1.67-10.77];p=.002), Killip class II (HR=8.80; 95% CI[2.72-28.41];p<.001), III (HR=5.88; 95% CI [0.99-34.80]; p=.051) and IV (HR=9.60; 95% CI[1.86-48.59];p=.007), Acute Kidney Injury (HR=2.47; 95% CI[1.00-6.13];p=.051) and days of hospitalization (HR=1.04; 95% CI[1.01-1.08];p=.030) but not female gender (HR=0.83; 95% CI[0.33-2.10];p=.690) as independent prognostic factors of mortality. Conclusions Compared to men, women with STEMI undergoing primary PCI have higher mortality rates. Women admitted for STEMI have a worse risk profile, are treated with a higher reperfusion time related with system delays and are less likely to receive the recommended therapy. Female gender was not an independent prognostic factor for mortality in the studied population.

Acompanhamento de Dois Anos de Pacientes com Cardiopatia Isquêmica Crônica em um Centro Especializado no Brasil / Two-Year Follow-Up of Chronic Ischemic Heart Disease Patients in a Specialized Center in Brazil

Resumo Fundamento A incidência de eventos cardiovasculares em pacientes com doença cardíaca isquêmica crônica (DCIC) pode variar significativamente entre os países. Embora populoso, o Brasil é frequentemente sub-representado nos registros internacionais. Objetivos Este estudo teve como objetivo descrever a qualidade do atendimento e a incidência de eventos cardiovasculares em dois anos, além de fatores prognósticos associados em pacientes com DCIC em um centro terciário de saúde pública no Brasil. Métodos Pacientes com DCIC que compareceram para avaliação clínica no Instituto do Coração (São Paulo, Brasil) foram cadastrados e acompanhados por dois anos. O desfecho primário foi um composto de infarto do miocárdio (IM), acidente vascular encefálico ou morte. Um nível de significância de 0,05 foi adotado. Resultados De janeiro de 2016 a dezembro de 2018, 625 participantes foram incluídos no estudo. As características basais mostram que 33,1% eram mulheres, a idade mediana era de 66,1 [59,6 - 71,9], 48,6% tinham diabetes, 83,1% tinham hipertensão, 62,6% tinham IM prévio e 70,4% passaram por algum procedimento de revascularização. Em um acompanhamento mediano de 881 dias, 37 (7,05%) desfechos primários foram observados. Após ajustes, idade, acidente vascular encefálico prévio e colesterol LDL foram independentemente associados ao desfecho primário. Comparando a linha de base com o acompanhamento, os participantes relataram alívio da angina com base na escala da Sociedade Cardiovascular Canadense (SCC) de acordo com as seguintes porcentagens: 65,7% vs. 81,7% eram assintomáticos e 4,2% vs. 2,9% eram SCC 3 ou 4 (p < 0,001). Eles também relataram melhor qualidade na prescrição de medicamentos: 65,8% vs. 73,6% (p < 0,001). No entanto, não houve melhora no colesterol LDL ou no controle da pressão arterial. Conclusão O presente estudo mostra que pacientes com DCIC apresentaram uma incidência de 7,05% do desfecho primário composto em um período de dois anos, sendo a diminuição do colesterol LDL o único fator de risco modificável associado ao prognóstico.

Abstract Background The incidence of cardiovascular events in patients with chronic ischemic heart disease (CIHD) may vary significantly among countries. Although populous, Brazil is often underrepresented in international records. Objectives This study aimed to describe the quality of care and the two-year incidence of cardiovascular events and associated prognostic factors in CIHD patients in a tertiary public health care center in Brazil. Methods Patients with CIHD who reported for clinical evaluation at Instituto do Coração (São Paulo, Brazil) were registered and followed for two years. The primary endpoint was a composite of myocardial infarction (MI), stroke, or death. A significance level of 0.05 was adopted. Results From January 2016 to December 2018, 625 participants were included in the study. Baseline characteristics show that 33.1% were women, median age 66.1 [59.6 - 71.9], 48.6% had diabetes, 83.1% had hypertension, 62.6% had previous MI, and 70.4% went through some revascularization procedure. At a median follow-up (FU) of 881 days, we noted 37 (7.05%) primary endpoints. After adjustments, age, previous stroke, and LDL-cholesterol were independently associated with the primary endpoint. Comparing baseline versus FU, participants experienced relief of angina based on the Canadian Cardiovascular Society (CCS) scale according to the following percentages: 65.7% vs. 81.7% were asymptomatic and 4.2% vs. 2.9% CCS 3 or 4 (p < 0.001). They also experienced better quality of medication prescription: 65.8% vs. 73.6% (p < 0.001). However, there was no improvement in LDL-cholesterol or blood pressure control. Conclusion This study shows that CIHD patients had a two-year incidence of the primary composite endpoint of 7.05%, and the reduction of LDL-cholesterol was the only modifiable risk factor associated with prognosis.

Estrategia fármaco-invasiva en el manejo del infarto agudo al miocardio con supradesnivel del ST / Pharmaco-invasive approach in the management of acute myocardial infarction. Analysis of 144 cases

BACKGROUND: In those patients who do not have timely access to primary angioplasty, the pharmaco-invasive approach, that is, the use of thrombolysis as a bridging measure prior to the coronary angiography, is a safe alternative. AIM: To describe the features of patients with an acute ST-elevation myocardial infarction (STEMI) treated with a pharmaco-invasive strategy. MATERIAL AND METHODS: Descriptive observational study of 144 patients with mean age of 46 years with STEMI who received a dose of thrombolytic prior to their referral for primary angioplasty at a public hospital between 2018 and 2021. RESULTS: There were no differences the clinical presentation according to the Killip score at admission between thrombolyzed and non-thrombolyzed patients (p = ns). Fifty-three percent of non-thrombolyzed patients were admitted with an occluded vessel (TIMI 0) compared with 27% of thrombolyzed patients (p < 0.001). The thrombolyzed group required significantly less use of thromboaspiration (3.5 and 8.4% respectively; p = 0.014). Despite this, 91 and 92% of non-thrombolyzed and thrombolyzed patients achieved a post-angioplasty TIMI 3 flow. Long-term survival was 91 and 86% in thrombolyzed and non-thrombolyzed patients, respectively (p = ns). CONCLUSIONS: The pharmaco-invasive strategy is a safe alternative when compared to primary angioplasty in centers that don't have timely access to Interventional Cardiology.

Sobrevida a largo plazo de pacientes con infarto agudo del miocardio en presencia de oclusiones crónicas totales en vaso no culpable / Prognostic value of the presence of a chronic total occlusion in patients with acute myocardial infarction

BACKGROUND: The presence of a chronic total occlusion (CTO) in a non-infarct-related artery in patients with acute myocardial infarction (AMI), may be a sign of bad prognosis. AIM: To estimate the long-term survival of patients with AMI who were studied with coronarography during 2013-2014 who had one or more CTO in a non-infarct-related artery. MATERIAL AND METHODS: Review of coronary angiograms performed between 2013 and 2014 to patients with an AMI. Patients were grouped as having or not a CTO in a non-infarct-related artery. Their medical records were reviewed, and mortality was determined requesting their death certificates. RESULTS: Of 993 patients with AMI under-going coronarography, 233 (23.5%) had at least one CTO. Patients with CTO were older (66 and 62 years respectively). They also had a higher prevalence of hypertension, diabetes mellitus (DM), kidney failure and moderate to severe systolic ventricular dysfunction. The independent predictors of mortality were CTO, age, DM and kidney failure. Survival at an average follow-up period of 57 months was significantly higher in patients without CTO (89.5 and 80.3% respectively, p < 0.01). CONCLUSIONS: The presence of CTO in patients with acute myocardial infarction is associated with a higher frequency of cardiovascular risk factors and lower long-term survival.

Rotura del septum interventricular post infarto agudo al miocardio: una complicación potencialmente letal Revisión de la literatura a propósito de un caso clínico / Ventricular septal rupture after acute myocardial infarction: a potentially lethal complication Case report and literature review

Rupture of the ventricular septum with the appearance of an interventricular communication is an infrequent and life-threatening mechanical complication after acute myocardial infarction. The advent of coronary reperfusion therapies has reduced the incidence of this complication, but mortality remains high. The clinical presentation varies from mild compromise with exertional dyspnea to severe compromise with cardiogenic shock. In this pathology, early diagnosis is fundamental and surgical repair is the treatment of choice. In this article we report an interesting clinical case about a 77-year-old woman who was belatedly referred to our hospital and diagnosed with postinfarction rupture of the ventricular septum with an unfortunately fatal evolution. Relevance of this case lies in its atypical clinical presentation which led to a delay in diagnosis and a missed opportunity for early reperfusion therapy. An updated literature review about rupture of the ventricular septum complicating acute myocardial infarction was carried out.

Estado periodontal de pacientes con cardiopatía isquémica / Periodontal state of patients with ischemic heart disease

Introducción: En numerosos estudios realizados en las últimas 3 décadas, se ha tratado de atribuir una relación causal a la enfermedad periodontal en la fisiopatología de la cardiopatía isquémica. Objetivo: Caracterizar el estado periodontal de pacientes con cardiopatía isquémica y algunos factores de riesgo cardiovascular. Métodos: Se realizó un estudio transversal de 50 pacientes, atendidos en la sala de cuidados coronarios del Hospital Provincial Vladimir Ilich Lenin de Holguín, desde septiembre de 2019 hasta enero de 2020. Se evaluó el estado periodontal mediante el Índice Periodontal de Russell simplificado. Se exploraron algunos factores de riesgo de la cardiopatía isquémica y se emplearon métodos teóricos, empíricos, así como la estadística descriptiva. Resultados: En la serie predominó el grupo de 60-69 años de edad (23 para 46,0 %); 56,0 % de los pacientes presentó infarto agudo de miocardio y 62,0 % periodontitis avanzada. Entre los factores de riesgo cardiovascular más frecuentes figuraron: hipertensión arterial (74,0 %) y tabaquismo (70,0 %). Conclusiones: En este estudio se halló, en gran medida, la periodontitis crónica en pacientes con cardiopatía isquémica, lo cual sirve de pauta para la toma de decisiones de médicos y estomatólogos.

Introduction: In numerous studies carried out in the last 3 decades, it has been tried to attribute a causal relationship to the periodontal disease in the pathophysiology of the ischemic heart disease. Objective: To characterize the periodontal state of patients with ischemic heart disease and some cardiovascular risk factors. Methods: A cross-sectional study of 50 patients, assisted in the Coronary Cares Service of Vladimir Ilich Lenin Provincial Hospital in Holguín, was carried out from September, 2019 to January, 2020. The periodontal state was evaluated by means of the Russell Periodontal Index simplified. Some risk factors of the ischemic heart disease were explored and theoretical, empiric methods were used, as well as the descriptive statistic. Results: In the series there was a prevalence of the 60-69 age group (23 for 46 %); 56.0 % of the patients presented acute myocardial infarction and 62.0 % presented advanced periodontitis. Among the most frequent cardiovascular risk factors we can mention: hypertension (74.0 %) and nicotine addiction (70.0 %). Conclusions: In this study it was found, in great measure, the chronic periodontitis in patients with ischemic heart disease, which serves as rule for the decisions making of doctors and dentists.

Influence of Factors Affecting Quality of Life on in-Hospital Cardiovascular Events of Patients with Acute Myocardial Infarction with and without ST-segment Elevation

Abstract Background Acute myocardial infarction (AMI), with and without ST-segment elevation (STEMI and NSTEMI, respectively), is the principal cause of cardiovascular morbidity and mortality in Brazil and around the world. Modifiable risk factors (RF) and quality of life (QOL) may correlate with the type of AMI. Objective To evaluate the influence of QOL and RF on the type of AMI and in-hospital cardiovascular events in STEMI and NSTEMI patients. Methods This was an observational, cross-sectional study. Patients with AMI attending four referral hospitals (three private and one public) for cardiovascular disease treatment were assessed for QOL using the Brazilian version of the 36-item short form survey. A p < 0.05 was considered statistically significant. Results We evaluated 480 volunteers; 51% were treated in one of the private hospitals. In total, 55.6% presented with STEMI, and 44.4% with NSTEMI. Patients from the public hospital were 8.56 times more likely to have STEMI compared to those from the private hospitals. There was a higher prevalence of smokers in STEMI (p < 0.028) patients. QOL was not associated with the type of AMI. A negative patient perception of the physical health and pain domains was observed. Although a significant difference between the physical and the mental health domains was not observed, individual domains were correlated with some in-hospital outcomes. Conclusion There was a higher prevalence of smokers among individuals with STEMI. Domains of QOL showed a statistically significant relationship with the occurrence of in-hospital cardiovascular events, with no difference between the types of AMI.

How much do the Patients with Acute Myocardial Infarction Know about Chest Pain, Thrombolytic Therapy, and Other Factors Affecting the Treatment Time in the Emergency Room?

Abstract Background: Treatment time in the emergency room for acute myocardial infarction is very important and can be life-saving if one understands the importance of a patient's chest pain. Objetice: The aim of this study is to evaluate how much patients entering the emergency room due to acute myocardial infection (AMI) know about chest pain and thrombolytic therapy. Materials and Methods: One hundred fifty patients (126 males,14 females) from three different institutes with complaints of chest pain were randomly chosen to participate in this study. The mean age of the patients was 55.4 ± 11.2 years (71+33). Patients were asked to fill out a questionnaire consisting of 70 questions within the first seven days. All differences in categorical variables were computed using the χ2-test and Fisher Exact test. A two-tailed hypothesis was used in all statistical evaluations, and p<0.05 was considered significant. Results: It was observed that 17% of the patients came to the hospital within the first 30 minutes; 18.3% of them came to the hospital between 30 minutes and 1 hour; 27.5% of them came to the hospital between 1 hour and 3 hours; and 21.4% of them came to the hospital more than 6 hours after symptoms began. It was also observed that 68% of the patients were not aware of the AMI, and 96% of them had no prior knowledge of antithrombolytic therapy. Conclusion: Because the majority of the patients did not have enough information about AMI, a training program should be implemented to ensure that people to come to the hospital earlier.

Factores predictivos de mortalidad en el infarto agudo de miocardio con elevación del segmento ST / Predictive factors of mortality in ST-segment elevation acute myocardial infarction

RESUMEN Introducción: Las enfermedades cardiovasculares son la mayor causa de mortalidad del orbe. A pesar de que la incidencia del infarto de miocardio ha disminuido en Estados Unidos, sustancialmente en las últimas décadas, no han dejado de tener un fuerte impacto socioeconómico-laboral. Objetivo: Identificar los factores predictivos de mortalidad en los pacientes con infarto agudo de miocardio con elevación del segmento ST (IMACEST). Método: Se realizó un estudio analítico con 118 pacientes, ingresados en dos hospitales de Santiago de Cuba, durante el período comprendido entre enero de 2017 y diciembre de 2019. El análisis de los datos se basó en la construcción de un modelo multivariado (regresión logística multivariable) para identificar los factores predictivos de la mortalidad. Resultados: Hubo un total de 15 fallecidos durante el período de hospitalización. En la investigación los hombres marcaron la diferencia, sin poder asociar estadísticamente la variable de género con la mortalidad; sin embargo, la edad mayor a 80 años (RR 7,89; IC 95%: 1,97-7,93; p<0,0001), el shock cardiogénico (RR 8,12; IC 95%: 2,85-9,18; p=0,001), no aplicar la trombólisis (RR 9,13; IC 95%: 3,32-9,45; p=0,001), la ventana terapéutica mayor de 6 horas (RR 16,96; IC 95%: 9,79-62,90; p<0,0001), y la localización inferior del infarto (RR 7,89; IC 95%: 1,97-7,93; p<0,0001), mostraron una asociación estadística muy significativa con la mortalidad. Conclusiones: Se identificaron algunos factores predictivos de mortalidad para el IMACEST, donde la edad mayor a los 80 años, el shock cardiogénico y una ventana terapéutica mayor de seis horas se erigen como los principales factores causales en la explicación fisiopatológica y estadística de la mortalidad.

ABSTRACT Introduction: Cardiovascular diseases are the top cause of mortality worldwide. Although the incidence of myocardial infarction has decreased substantially in the United States in recent decades, they have not ceased to have a strong socioeconomic and occupational impact. Objective: To identify predictive factors of mortality in patients with ST-segment elevation myocardial infarction (STEMI). Method: An analytical study was carried out in 118 patients, admitted to two hospitals in Santiago de Cuba, from January 2017 to December 2019. Data analysis was based on the construction of a multivariate model (multivariable logistic regression) to identify predictors of mortality. Results: There were 15 deaths in total during hospitalization period. In the research, men marked the difference, without being able to statistically associate this gender variable with mortality; however, age over 80 years old (RR 7.89; 95% CI: 1.97-7.93; p<0.0001), cardiogenic shock (RR 8.12; CI 95%: 2.85-9.18; p=0.001), not applying thrombolysis (RR 9.13; CI 95%: 3.32-9.45; p=0.001), therapeutic window greater than six hours (RR 16.96; CI 95%: 9.79-62.90; p<0.0001), and the inferior wall myocardial infraction (RR 7.89; CI 95%: 1.97-7.93; p<0.0001), showed a highly significant statistical association with mortality. Conclusions: Some predictive factors of mortality were identified for STEMI, where age older than 80 years old, cardiogenic shock and a therapeutic window longer than six hours stand as the main causal factors in the pathophysiological and statistical explanation of mortality.

Óbitos intra e extra-hospitalares por infarto agudo do miocárdio nas capitais brasileiras / In- and out-of-hospital deaths by acute myocardial infarction in brazilian state capitals

Resumo Fundamento: O infarto agudo do miocárdio (IAM) é a principal causa de óbito no Brasil e no mundo. Aproximadamente metade dos óbitos ocorrem fora do ambiente hospitalar. Objetivos: Analisar a distribuição, a evolução temporal e as características sociodemográficas (CSD) dos óbitos intra e extra-hospitalares por IAM nas capitais brasileiras e a sua relação com indicadores municipais de desenvolvimento (IMD). Métodos: Estudo ecológico com contagem anual dos óbitos por IAM nas 27 capitais brasileiras de 2007 a 2016, os quais foram divididos em dois grupos, intra-hospitalar (H) e extra-hospitalar (EH). Avaliou-se a evolução temporal das taxas de mortalidade em cada grupo e as diferenças das CSD. Modelos de regressão binominal negativa compararam temporalmente a contagem de óbitos em cada grupo com as seguintes variáveis: residir nas regiões Sul e Sudeste (S/SE), índice de desenvolvimento humano municipal (IDHM), índice de Gini e expectativa de anos de estudo (EAE). Considerou-se estatisticamente valores significativos de p < 0,05. Resultados: A taxa de mortalidade EH para o conjunto das capitais aumentou ao longo do tempo. Todas as CSD pesquisadas foram difententes entre os grupos (p < 0,001). No grupo EH prevaleceram os óbitos em homens, em pacientes ≥ 80 anos e em solteiros. O S/SE elevou a incidência de óbitos extra-hospitalares (IRR = 2,84; IC 95% = 1,67-4,85), enquanto o maior EAE registrou queda (IRR = 0,86; IC 95% = 0,77-0,97). Para o grupo H, o maior IDHM reduziu a incidência de óbitos (IRR = 0,44; IC 95% = 0,33-0,58), enquanto o maior EAE apresentou crescimento (IRR = 1,09; IC 95% = 1,03-1,15). Conclusão: Os óbitos intra e extra-hospitalares por IAM nas capitais apresentam diferenças sociodemográficas, incidência influenciada por IMD e progressivo aumento da ocorrência extra-hospitalar.

Abstract Background: Acute myocardial infarction (AMI) is the main cause of death in Brazil and the world. Approximately half of these deaths occur outside the hospital. Objectives: To analyze the distribution, temporal evolution, and sociodemographic characteristics (SDC) of in- and out-of-hospital deaths by AMI in Brazilian state capitals and their relationship with municipal development indicators (MDI). Methods: This is an ecological study of the number of deaths due to AMI reported annually by the 27 Brazilian state capitals from 2007 to 2016; these were divided into 2 groups: in-hospital (H) and out-of-hospital (OH). We evaluated the temporal evolution of mortality rates in each group and differences in SDC. Negative binomial regression models were used to compare the temporal evolution of the number of deaths in each group with the following variables: residing in the South/Southeast regions (S/SE), municipal human development index (MHDI), Gini coefficient, and expected years of schooling (EYS). We considered p-values<0.05 as statisticallysignificant. Results: The OH mortality rate increased with time for all state capitals. All studied SDC were different between groups (p<0.001). In the OH group, most deaths were of men and patients aged 80 years or older and not married. S/SE increased the incidence of OH deaths (incidence rate ratio [IRR]=2.84; 95% confidence interval [CI]=1.67-4.85), while higher EYS reduced it (IRR=0.86; 95% CI=0.77-0.97). In the H group, higher MHDI reduced the incidence of deaths (IRR=0.44; 95% CI=0.33-0.58), while higher EYS increased it (IRR=1.09; 95% CI=1.03-1.15). Conclusions: In- and out-of-hospital deaths due to AMI in Brazilian state capitals were influenced by MDI, presented sociodemographic differences and a progressive increase in out-of-hospital occurrences.

A Molécula de Lesão Renal-1 está Associada à Nefropatia Induzida por Contraste em Pacientes Idosos com IAMSSST / Kidney Injury Molecule-1 Is Associated with Contrast-Induced Nephropathy in Elderly Patients with Non-STEMI

Resumo Fundamento A nefropatia induzida por contraste (NIC) está associada a um risco aumentado de eventos cardiovasculares adversos maiores (ECAM), e a associação entre NIC e mecanismos oxidativos está bem documentada. Objetivo Este estudo visou avaliar a relação entre os níveis séricos da molécula de lesão renal-1 (KIM-1) e a NIC em pacientes idosos com infarto do miocárdio sem supradesnivelamento do segmento ST (IAMSSST). Métodos O presente estudo incluiu um total de 758 pacientes com IAMSSST que foram submetidos a intervenção coronária percutânea (ICP); 15 desenvolveram NIC após a ICP e outros 104 constituíram o grupo controle, pareado por idade > 65 anos. Foram registrados os valores laboratoriais desde a linha de base até o período entre 48 e 72 horas e os achados clínicos. Os pacientes foram acompanhados durante um ano. Foram considerados significativos valores de p < 0,05. Resultados A NIC foi observada em 12,60% dos pacientes. A KIM-1 sérica foi significativamente mais alta no grupo com NIC que no grupo sem NIC (14,02 [9,53 - 19,90] versus 5,41 [3,41 - 9,03], p < 0,001). O escore Mehran foi significativamente mais alto no grupo com NIC do que no grupo sem NIC (14 [5 - 22] versus 5 [2 - 7], p = 0,001). Os ECAM foram significativamente maiores no grupo com NIC do que no grupo sem NIC (7 [46,70%] versus 12 [11,50%], p = 0,001). A análise de regressão logística multivariada mostrou que o nível de KIM-1 basal (OR = 1,652, IC 95%: 1,20 - 2,27, p = 0,002) e o escore Mehran (OR = 1,457, IC 95%: 1,01 - 2,08, p = 0,039) foram preditores independentes da NIC em pacientes idosos com IAMSSST. Conclusão A concentração sérica basal de KIM-1 e o escore de Mehran são preditores independentes de NIC em pacientes idosos com IAMSSST. Além disso, todas as causas de mortalidade, morte cardiovascular, reinfarto do miocárdio, acidente vascular cerebral e MACE foram significativamente maiores no grupo CIN no acompanhamento de um ano.

Abstract Background Contrast-induced nephropathy (CIN) is associated with an increased risk of major adverse cardiovascular events (MACE), and the association between CIN and oxidative mechanisms is well documented. Objective This study aimed to evaluate the relationship between serum levels of kidney injury molecule-1 (KIM-1) and CIN in elderly patients with non-ST-segment elevation myocardial infarction (NSTEMI). Methods This study included a total of 758 patients with NSTEMI, who underwent percutaneous coronary intervention (PCI); 15 developed CIN after PCI, and another 104 were the control group, matched for age > 65 years. Baseline to 48-to-72-hour laboratory values and clinical outcomes were recorded. Patients were followed during one year. P values of < 0.05 were considered significant. Results CIN was observed in 12.60% of the patients. Serum KIM-1 was significantly higher in the CIN group than in the non-CIN group (14.02 [9.53 - 19.90] vs. 5.41 [3.41 - 9.03], p < 0.001). The Mehran score was significantly higher in the CIN group than in the non-CIN group (14 [5 - 22] vs. 5 [2 - 7], p = 0.001). MACE were significantly higher in the CIN group than in the non-CIN group (7 [46.70%] vs. 12 [11.50%], p = 0.001). Multivariate logistic regression analysis showed that baseline KIM-1 level (OR = 1.652, 95% CI: 1.20 - 2.27, p = 0.002) and Mehran score (OR = 1.457, 95% CI: 1.01 - 2.08, p = 0.039) were independent predictors of CIN in elderly patients with NSTEMI. Conclusion Baseline serum KIM-1 concentration and Mehran score are independent predictors of CIN in elderly patients with NSTEMI. Additionally, all-cause mortality, cardiovascular death, myocardial reinfarction, stroke, and MACE were significantly higher in the CIN group at one-year follow-up.

El 86,6 % de los casos no recibió trombolisis y el 6,6 % tuvo algún criterio de reperfusión pos-estreptoquinasa (p=0,00). El 36,6 % de los casos presentó choque cardiogénico (p=0,003), ruptura cardíaca (30 %) (p=0,03), y taponamiento (23,3 %) (p=0,01). Conclusiones: Los factores predictores de mortalidad hospitalaria en pacientes con infarto agudo del miocardio son: la edad avanzada, el tiempo prolongado entre el inicio de los síntomas y la asistencia médica, la existencia de las complicaciones, tales como el choque cardiogénico, el taponamiento cardíaco y la ruptura cardíaca, así como la no administración de tratamiento trombolítico y la ausencia de reperfusión.

ABSTRACT Introduction: Cardiovascular disease is the main cause of death worldwide. Objective: To identify the predictor factors of hospital mortality in patients with acute myocardial infarction at the Hospital General Docente "Dr. Agostinho Neto" in 2017. Method: A retrospective analytical case-control study was performed in a population of 90 patients with myocardial infarction. The case-cohort study included all patients who died during admission (n=30) and met the inclusion and exclusion criteria, while the case-control study included 60 patients who were discharged alive, randomly selected by simple random sampling. Results: The mean age was higher in the case-cohort studied (74.06 years) than the case-control (p=0.021). The 86,6% of cases did not receive thrombolysis and 6.6% had some reperfusion criteria after the streptokinase (p=0.00). Cardiogenic shock (p=0.003), cardiac rupture (30%) (p=0.03), and cardiac tamponade (23.3%) (p=0.01) were present in 36.6% of cases. Conclusions: The predictor factors of hospital mortality in patients with acute myocardial infarction are as follows: age, the prolonged time between the onset of symptoms and medical attention, presence of complications such as cardiogenic shock, cardiac tamponade and cardiac rupture, as well as the non-administration of thrombolytic treatment and the absence of reperfusion.

Rendimiento de ecuaciones para predecir riesgo cardiovascular en una población de Argentina / Performance of equations to predict cardiovascular risk in an Argentine population

Resumen El rendimiento de las ecuaciones existentes de predicción de riesgo cardiovascular (RCV) en población argentina es desconocido. Se comparó RCV estimado por dichas ecuaciones, con la ocurrencia de eventos cardiovasculares (ECV) en una población de pacientes sin enfermedad cardiovascular de un hospital argentino. Se incluyeron aleatoriamente adultos entre 40 y 70 años, excluyéndose quienes al momento del enrolamiento presentaban historia de ECV mayor, cáncer activo, o tratamiento hipolipemiante. Se calculó RCV a 10 años al momento de inclusión, utilizando ecuaciones de Framingham 2008, SCORE (para poblaciones de bajo y alto riesgo), ATP III, Organización mundial de la saludregión América B (OMS-B) y Ecuación de Cohorte Agrupada (ECA). El fin de seguimiento fue 10 años ± 6 meses, ocurrencia de infarto de miocardio fatal o muerte por cualquier causa. Se utilizaron curvas ROC para evaluar discriminación (ABC > 0.75 buena discriminación). La calibración se evaluó mediante chi-cuadrado de Hosmer Lemeshow (Chi > 20 o p < 0.05 pobre calibración). Incluimos 606 pacientes, 366 mujeres, edad promedio 56.7 ± 8.4 años. Se observaron 10 (1.7%) muertes de causa no cardiovascular, 5 (0.8%) causa cardiovascular. Se registraron 58 (9.8%) ECV no fatales. Hubo aceptable discriminación para ecuaciones de Framingham, ATP-III y ECA. La calibración global solo fue buena con las ecuaciones de ATP-III y ECA. La frecuencia observada de ECV fue baja, y hubo sobreestimación de RCV con todas las ecuaciones. Sin embargo, se podría sugerir la aplicación de las ecuaciones de ATP-III o ECA en esta población.

Abstract The performance of available risk scores to predict cardiovascular risk (CVR) in the Argentinian population is unknown. Our aim was to compare the CVR predicted by several equations with the occurrence of cardiovascular events (CVE) in patients without known cardiovascular disease in an Argentinian hospital. Adults between 40 and 70 years were randomly selected, excluding those with prior history of major CVE, active cancer, lipid lowering treatment and absence of follow-up data. Framingham 2008, SCORE (low and high-risk populations), ATP III, World Health OrganizationAmerican B region (WHO-B) and Pooled Cohort equations (PC) risk scores were used to calculate 10-y CVR at time of enrollment. End of follow-up was 10 years ± 6 months, occurrence of fatal myocardial infarction or death from any cause. We used ROC curves to assess discrimination (AUC > 0.75 good discrimination), and Hosmer Lemeshow chi-square to evaluate calibration (Chi > 20 or p value < 0.05 poor calibration). We included 606 patients in our study, 336 women, average age 56.7 ± 8.4 year. Of those, 10 (1.7%) non-cardiovascular deaths, and 5 (0.8%) cardiovascular deaths were observed. 58 (9.8%) a non-fatal CVE were recorded. There was acceptable discrimination for Framingham, ATP-III, and both PC equations. The global calibration was only good with the ATP-III and PC equations. The observed frequency of CVE was low, and the CVR was overestimated by all equations. However, applying ATP-III or PC equations to assess CVR could be considered in our population.

Infarto agudo de miocardio en cuatro hospitales de atención secundaria en Cuba en la era COVID-19 / Acute myocardial infarction in four secondary care hospitals in Cuba in the COVID-19 era

RESUMEN Introducción: Las características clínico-epidemiológicas en el diagnóstico, evolución y tratamiento de los pacientes con infarto agudo de miocardio en la era COVID-19 dependen de varios factores. Objetivos: Precisar el comportamiento de algunas variables clínico-epidemiológicas en la atención y tratamiento de los pacientes con infarto agudo de miocardio en el curso de la COVID-19. Método: Se realizó un estudio observacional en cuatro hospitales de atención secundaria en Cuba. Se utilizaron las siguientes variables: número de ingresos por infartos, mortalidad hospitalaria, tiempo de demora mayor de 4 horas desde el inicio de los síntomas y la llegada a la primera asistencia médica y el porcentaje de trombólisis. Se definieron dos grupos, los ingresados entre el 1 de marzo al 30 de septiembre de 2019 (Grupo I) y los ingresados en igual período pero del 2020 (Grupo II). Las comparaciones entre ambos grupos se realizaron utilizando el test de Chi cuadrado. Resultados: Existió una disminución de 53 ingresos por infarto agudo de miocardio en Las Tunas (112 vs. 159, p<0.05), con un incremento del número de ingresos en el Hospital Enrique Cabrera en los pacientes del grupo II (98 vs. 68, p<0.05). Se incrementó el número de fallecidos y la mortalidad hospitalaria en el grupo II en todos los centros con relación al grupo I. En la mayoría de los centros se incrementó la demora desde el inicio de los síntomas y la llegada al lugar de la primera asistencia médica. El porciento de trombólisis fue superior al 50% en la mayoría de los centros en el grupo II. Conclusiones: Las características de la COVID-19 pueden modificar aspectos clínicos y epidemiológicos en la atención y tratamiento de los pacientes con infarto agudo de miocardio.

ABSTRACT Introduction: The clinico-epidemiological characteristics in the diagnosis, evolution and treatment of patients with acute myocardial infarction in the COVID-19 era depend on several factors. Objectives: To determine the behavior of some clinico-epidemiological variables in the management of patients with acute myocardial infarction during de COVID-19 pandemic. Methods: An observational study was carried out in four secondary care hospitals in Cuba. The following variables were used: number of admission due to acute myocardial infarction, hospital mortality, delay longer than four hours from the beginning of the symptoms to the arrival to the first medical assistance, and thrombolysis percentage. Two groups were defined, those admitted from March 1st to September 30th, 2019 (Group I) and those admitted in the same period, but from 2020 (Group II). Comparisons between both groups were made using the chi square test. Results: There was a decrease of 53 admissions due to acute myocardial infarction in Las Tunas (112 vs. 159; p<0.05), with an increase in the number of admissions in the Hospital Enrique Cabrera in patients from Group II (98 vs. 68; p<0.05). The number of deaths and hospital mortality in Group II increased in all the centers in relation to Group I. In most of the hospitals there was an increase of the time elapsed from the beginning of the symptoms to the arrival to the first medical assistance. Thrombolysis percentage in Group II was higher than 50% in most of the centers. Conclusions: The characteristics of COVID-19 may modify the clinical and epidemiological aspects in the management of patients with acute myocardial infarction.

Tempos de atendimento e desfechos no infarto agudo do miocárdio com supradesnivelamento ST / Time of care and outcomes in ST-segment elevation myocardial infarction

Objetivo: Comparar os tempos de tratamento dor-porta e porta-balão em indivíduos com infarto agudo do miocárdio com supradesnivelamento ST com os desfechos cardiovasculares em 30 dias. Métodos: Trata-se de uma coorte histórica, realizada por meio da pesquisa de prontuários eletrônicos e dos bancos de dados já existentes dos serviços de hemodinâmica de todos os indivíduos atendidos com diagnóstico de infarto agudo do miocárdio com supradesnivelamento ST e submetidos à angioplastia, no período de março de 2015 a setembro de 2016, em dois hospitais públicos de grande porte de Porto Alegre (RS). Os desfechos foram o óbito intra-hospitalar e em 30 dias e os eventos cardíacos maiores hospitalares e em 30 dias. Resultados: Foram avaliadas as informações de 808 indivíduos, sendo 26,9% provenientes do Hospital de Clínicas de Porto Alegre e 73,1% do Instituto de Cardiologia ­ Fundação Universitária de Cardiologia. Não houve diferença significativa na caracterização da amostra. Um terço dos indivíduos analisados apresentou tempo dor- -porta menor ou igual a 180 minutos, e 72% tiveram tempo porta-balão menor que 90 minutos. A mediana do tempo total de isquemia foi de 338 minutos. Na avaliação dos tempos não houve diferença significativa entre os dois hospitais. Para eventos cardíacos maiores e óbitos intra- -hospitalares, o único tempo que se mostrou significativo, após o ajuste multivariado, foi o porta-balão, em que os indivíduos com tempo maior que 90 minutos apresentaram razão de risco de 1,06 (IC95% 1,02-1,11) e 5,78 (IC95% 1,44-23,2), respectivamente, para eventos cardíacos maiores e óbitos intra-hospitalares. Para eventos cardíacos maiores total e óbito total, nenhum dos três tempos se associou significativamente com o desfecho após ajuste. Contudo, o tempo porta-balão maior ou igual a 90 minutos também foi significativo para razão de risco bruto para ambos, assim como a dor-porta para óbito total. Conclusão: Os dados da pesquisa corroboram as recomendações internacionais para cumprimento dos menores tempos de atendimento, em especial do tempo porta-balão, para o bom prognóstico. Infelizmente, no país, o tempo de isquemia miocárdica ainda está muito aquém do ótimo, necessitando de melhorias na área para melhorar os desfechos nesses indivíduos.

Objective: To compare symptom-onset-to-door and door- -to-balloon times in individuals with ST-segment elevation myocardial infarction to the 30-day cardiovascular outcomes. Methods: This is a historical cohort, using electronic medical records and the existing databases of hemodynamic services of all individuals diagnosed with ST-segment elevation myocardial infarction undergoing angioplasty between March 2015 and September 2016, in two large public hospitals in Porto Alegre. The outcomes were in-hospital death and death in 30 days, and major adverse cardiac events in hospital and in 30 days. Results: The information of 808 patients was evaluated, with 26.9% from Hospital de Clínicas de Porto Alegre, and 73.1% from the Instituto de Cardiologia ­ Fundação Universitária de Cardiologia. There was no significant difference in the characterization of the sample. One-third of the individuals evaluated presented symptom-onset-to-door of 180 minutes or less, and 72% had door-to- -balloon time below 90 minutes. The median total ischemic time was 338 minutes. In the evaluation of the times, there was no significant difference between the two hospitals. For more major cardiac events and intra-hospital deaths, the only time that proved to be significant after the multivariate adjustment was the door-to-balloon time, in which individuals with time higher than 90 minutes had a risk ratio of 1.06 (95% CI 1.02-1.11) for major cardiac events and 5.78 (95% CI 1.44-23.2), for intra-hospital deaths. For total major adverse cardiac events and total death, none of the 3 times was significantly associated with the outcome after adjustment; however, door-to-balloon of 90 minutes or more was also significant for crude risk ratio for both, as well as symptom-onset-to-door for total death. Conclusion: The research data corroborate the international recommendations to meet shorter service times, especially door-to-balloon time, for a good prognosis. Unfortunately, in the country, the time of myocardial ischemia is still far from optimal, requiring improvement in the area to improve the outcomes in these individuals.

O Escore Gensini e a Carga Trombótica Adicionam Valor Preditivo ao Escore SYNTAX na Detecção de No-Reflow após Infarto do Miocárdio / Gensini Score and Thrombus Burden Add Predictive Value to the SYNTAX Score in Detecting No-Reflow after Myocardial Infarction

Resumo Fundamento O fenômeno de no-reflow após a intervenção coronária percutânea está associado a um pior prognóstico em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST). O escore SYNTAX é um bom preditor de no-reflow. Objetivo Nosso objetivo foi avaliar se a carga aterosclerótica (escore Gensini) e a carga trombótica na artéria coronária culpada melhorariam a capacidade do escore SYNTAX para detectar o no-reflow. Métodos Neste estudo coorte prospectivo, foram estudados pacientes com IAMCSST consecutivos que se apresentaram dentro de 12 horas a partir do início dos sintomas. O no-reflow foi definido como fluxo TIMI < 3 ou fluxo TIMI =3 mas grau de blush miocárdico (myocardial blush grade) < 2. A carga trombótica foi quantificada de acordo com o grau TIMI de trombo (0 a 5). Resultados Foram incluídos 481 pacientes no estudo, com idade média de 61±11 anos. O fenômeno de no-reflow ocorreu em 32,8% dos pacientes. O escore SYNTAX (OR=1,05, IC95% 1,01-1,08, p<0,01), a carga trombótica (OR=1,17, IC95% 1,06-1,31, p<0,01), e o escore Gensini (OR=1,37, IC95% 1,13-1,65, p<0,01) foram preditores independentes do no-reflow. Os escores combinados apresentaram uma maior área sob a curva quando comparados ao escore SYNTAX isolado (0,78 [0,73-0,82] vs 0,73 [0,68-0,78], p=0,03). A análise da melhora da reclassificação líquida (NRI) categórica (0,11 [0,01-0,22], p=0,02) e contínua (NRI>0) (0,54 [0,035-0,73], p<0.001) mostrou melhora na capacidade preditiva do no-reflow no modelo combinado, com melhora da discriminação integrada (IDI) de 0,07 (0,04-0,09, p<0,001). Conclusões Nossos achados sugerem que, em pacientes com IAMCSST submetidos à intervenção coronária percutânea, a carga aterosclerótica e a carga trombótica na artéria culpada adicionam valor preditivo ao escore SYNTAX na detecção do fenômeno no-reflow.

Abstract Background No-reflow after percutaneous coronary intervention is associated with poor prognosis in patients with ST-segment elevation myocardial infarction (STEMI). SYNTAX score is a good predictor of no-reflow. Objective We aimed to evaluate whether atherosclerotic burden (Gensini score) and thrombus burden in the culprit coronary artery would improve the ability of the SYNTAX score to detect no-reflow. Methods In this prospective cohort study, consecutive patients with STEMI who presented within 12 h of onset of symptoms were selected for this study. No-reflow was defined as TIMI flow < 3 o r TIMI flow = 3 but myocardial blush grade <2. Thrombus burden was quantified according to the TIMI thrombus grade scale (0 to 5). Results A total of 481 patients were included (mean age 61±11 years). No-reflow occurred in 32.8%. SYNTAX score (OR=1.05, 95%CI 1.01-1.08, p<0.01), thrombus burden (OR=1.17, 95%CI 1.06-1.31, p<0.01), and Gensini score (OR=1.37, 95%CI 1.13-1.65, p<0.01) were independent predictors of no-reflow. Combined scores had a larger area under the curve than the SYNTAX score alone (0.78 [0.73-0.82] vs 0.73 [0.68-0.78], p=0.03). Analyses of both categorical (0.11 [0.01-0.22], p=0.02), and continuous net reclassification improvement (NRI>0) (0.54 [0.035-0.73], p<0.001) showed improvement in the predictive ability of no-reflow in the combined model, with integrated discrimination improvement (IDI) of 0.07 (0.04-0.09, p<0.001). Conclusions Our findings suggest that, in patients with STEMI undergoing percutaneous coronary intervention, atherosclerotic burden and thrombus burden in the culprit artery add predictive value to the SYNTAX score in detecting the no-reflow phenomenon.

Combined effects of nutritional status on long-term mortality in patients with non-st segment elevation myocardial infarction undergoing percutaneous coronary intervention

SUMMARY OBJECTIVE: The aim of this study was to investigate the performance of controlling nutritional status (CONUT) index, geriatric nutritional risk index (GNRI), and prognostic nutritional index (PNI) scores in predicting the long-term prognosis of patients with non-ST-elevated myocardial infarction (NSTEMI) who underwent percutaneous coronary intervention (PCI). METHODS: A total of 915 patients with NSTEMI (female: 48.4%; mean age: 73.1±9.0 years) who underwent PCI at Adana Numune Training and Research Hospital, Cardiology Clinic between January 2014 and January 2015 were included in this cross-sectional and retrospective study. CONUT, GNRI, and PNI scores were calculated based on the admission data derived from samples of peripheral venous blood. The mean follow-up duration was 64.5±15.4 months. RESULTS: During follow-up (mean 64.5±15.4 months), 179 patients (19.6%) died. The mean GNRI and PNI scores were significantly lower in the nonsurvivor group; however, the median CONUT score was significantly higher in the nonsurvivor group compared with the survivor group. The receiver operating characteristic (ROC) curve analyses have shown that GNRI score has similar performance to the CONUT score and has better performance than PNI score in predicting 5-year mortality. The Kaplan-Meier curve analysis has shown that patients with lower PNI or GNRI had higher cumulative mortality than the patients with higher PNI or GNRI. Also, the patients with higher CONUT scores had higher cumulative mortality compared with those with lower scores. The multivariate analyses have shown that GNRI (HR: 0.973), PNI (HR: 0.967), CONUT score (HR: 1.527), and body mass index (BMI) (HR: 0.818) were independent predictors of the 5-year mortality in patients with NSTEMI. CONCLUSION: In this study, we have shown that CONUT score, GNRI, and PNI values were associated with the long-term mortality in patients with NSTEMI who underwent PCI, and GNRI yielded similar results to CONUT score but was better than PNI.
