ABSTRACT

Introducción: El infarto del miocardio tipo 4a es una complicación del intervencionismo coronario percutáneo que incrementa el estado inflamatorio de los pacientes. Objetivo: Evaluar el valor diagnóstico del conteo absoluto de neutrófilos en la aparición de infarto del miocardio tipo 4a. Métodos: Se realizó una cohorte prospectiva en el Hospital Hermanos Ameijeiras. El universo estuvo constituido por 412 pacientes a los que se les realizó intervencionismo coronario percutáneo en el período comprendido de noviembre de 2018 a enero de 2021, la muestra fue de 232 pacientes. Se definieron variables clínicas, anatómicas, e inflamatorias. Resultados: Existieron diferencias significativas entre los pacientes con infarto tipo 4a y los que no tuvieron esta complicación según las variables clínicas: edad, índice de masa corporal, diabetes mellitus, enfermedad renal crónica y disfunción sistólica ventricular. La elevación del conteo absoluto de neutrófilos posterior al proceder con un área bajo la curva de 0,947 tuvo buena capacidad de discriminación de esta complicación (p = 0,000). En el diagnóstico de infarto periproceder el conteo absoluto de neutrófilos fue 7,35 posterior al proceder, tuvo una sensibilidad de 91,3 por ciento una especificidad de 96,2 por ciento. Conclusiones: Los neutrófilos fueron sensibles y específicos para el diagnóstico de infarto del miocardio tipo 4a(AU)


Introduction: Type 4 myocardial infarction is a complication of percutaneous coronary intervention that increases the inflammatory state of patients. Objective: To evaluate the diagnostic value of the absolute neutrophil count in the occurrence of type 4 myocardial infarction. Methods: A prospective cohort was carried out at Hermanos Ameijeiras Clinical Surgical Hospital. The universe consisted of 412 patients who underwent percutaneous coronary intervention from November 2018 to January 2021, two hundred thirty-two (232) patients form the sample. Clinical, anatomical and inflammatory variables were defined. Results: There were significant differences between patients with type 4 infarction and those who did not have this complication according to the clinical variables such as age, body mass index, diabetes mellitus, chronic kidney disease and ventricular systolic dysfunction. The subsequent elevation of the absolute neutrophil count when proceeding with an area under the 0.947 curve had good ability to discriminate this complication (p = 0.000). In the diagnosis of periprocedural infarction, the absolute neutrophil count was ≥ 7.35 after the procedure, it had 91.3percent sensitivity and 96.2percent specificity. Conclusions: Neutrophils were sensitive and specific for the diagnosis of type 4 myocardial infarction(AU)

ABSTRACT

Objective: To explore and compare the effect of standard or prolonged dual antiplatelet therapy (DAPT) on the long-term prognosis of elderly patients with coronary heart disease complicated with diabetes mellitus after drug-eluting stent (DES) implantation. Methods: Consecutive patients with diabetes mellitus, ≥65 years old, underwent DES implantation, and had no adverse events within 1 year after operation underwent percutaneous coronary intervention (PCI) from January to December 2013 in Fuwai Hospital were enrolled in this prospective cohort study. These patients were divided into three groups according to DAPT duration: standard DAPT duration group (11 ≤ DAPT duration≤ 13 months) and prolonged DAPT duration group (13<DAPT duration≤ 24 months; DAPT duration>24 months). All the patients were followed up at 1, 6 months, 1, 2 and 5 years in order to collect the incidence of major adverse cardiovascular and cerebrovascular events (MACCE), and type 2 to 5 bleeding events defined by the Federation of Bleeding Academic Research (BARC). MACCE were consisted of all cause death, myocardial infarction, target vessel revascularization or stroke. The incidence of clinical adverse events were compared among 3 different DAPT duration groups, and Cox regression model were used to analyze the effect of different DAPT duration on 5-year long-term prognosis. Results: A total of 1 562 patients were enrolled, aged (70.8±4.5) years, with 398 female (25.5%). There were 467 cases in standard DAPT duration group, 684 cases in 13<DAPT duration≤ 24 months group and 411 cases in DAPT duration>24 months group. The patients in standard DAPT duration group and the prolonged DAPT duration groups accounted for 29.9% (467/1 562) and 70.1% (1 095/1 562), respectively. The 5-year follow-up results showed that the incidence of all-cause death in 13<DAPT duration≤ 24 months group (4.8%(33/684) vs. 8.6%(40/467),P=0.011) and DAPT duration>24 month group(4.1%(17/411) vs. 8.6%(40/467),P=0.008) were significantly lower than in standard DAPT group. The incidence of myocardial infarction in 13<DAPT duration≤ 24 months group was lower than in standard DAPT duration group (1.9%(13/684) vs. 5.1%(24/467),P=0.002). The incidence of MACCE in 13<DAPT duration≤ 24 months group was the lowest (standard DAPT duration group, 13<DAPT duration≤ 24 months group and DAPT duration>24 month group were 19.3% (90/467), 12.3% (84/684), 20.2% (83/411), respectively, P<0.001). There was no significant difference in the incidence of stroke and bleeding events among the three groups (all P>0.05). Multivariate Cox analysis showed that compared with the standard DAPT group, prolonged DAPT to 13-24 months was negatively correlated with MACCE (HR=0.601, 95%CI 0.446-0.811, P=0.001), all-cause death (HR=0.568, 95%CI 0.357-0.903, P=0.017) and myocardial infarction (HR=0.353, 95%CI 0.179-0.695, P=0.003). DAPT>24 months was negatively correlated with all-cause death (HR=0.687, 95%CI 0.516-0.913, P=0.010) and positively correlated with revascularization (HR=1.404, 95%CI 1.116-1.765, P=0.004). There was no correlation between prolonged DAPT and bleeding events. Conclusions: For elderly patients with coronary heart disease complicated with diabetes mellitus underwent DES implantation, and had no MACCE and bleeding events within 1 year after operation, appropriately prolonging of the DAPT duration is related to the reduction of the risk of cardiovascular adverse events. Patients may benefit the most from the DAPT between 13 to 24 months. In addition, prolonging DAPT duration does not increase the incidence of bleeding events in this patient cohort.

ABSTRACT

INTRODUCTION@#Cardiovascular morbidity and mortality in end-stage renal failure (ESRF) patients are high. We examined the incidence and predictors of death and acute myocardial infarction (AMI) in ESRF patients on different modalities of dialysis.@*METHOD@#Data were obtained from a population-based database (National Registry Disease Offices) in Singapore. The study cohort comprised all adult patients initiated on dialysis between 2007 and 2012 who were closely followed for the development of death and AMI until September 2014. Cox regression methods were used to identify predictors of death and AMI.@*RESULTS@#Of 5,309 patients, 4,449 were on haemodialysis and 860 on peritoneal dialysis (PD). Mean age of the cohort was 61 (±13) years (44% women), of Chinese (67%), Malay (25%) and Indian (7%) ethnicities. By September 2014, the incidence of all-cause death was 34%; close to a third of the patients died from a cardiovascular cause. Age >60 years and the presence of ischaemic heart disease, diabetes, stroke, peripheral vascular disease and PD were identified as independent predictors of all-cause death. PD patients had lower odds of survival compared to patients on haemodialysis (hazard ratio 1.51, 95% confidence interval 1.35-1.70, P<0.0001). Predictors of AMI in this cohort were older age (>60 years) and the presence of ischaemic heart disease, diabetes, stroke, peripheral vascular disease and current/ex-smokers. There were no significant differences in the incidence of AMI between patients on PD and haemodialysis.@*CONCLUSION@#The short-term incidence of death and AMI remains high in Singapore. Future studies should investigate the benefits of a tighter control of cardiovascular risk factors among ESRF patients on dialysis.

Métodos: Se realizó una investigación descriptiva de tipo observacional, de corte transversal en el Consultorio Médico de Familia número 35, del Consejo Popular Ciro Redondo; Policlínico Camilo Cienfuegosˮ, San Cristóbal, Artemisa. El universo de estudio estuvo conformado por 145 pacientes con edades entre 40 y 60 años, residentes de la comunidad rural. La muestra la conformaron aquellos que cumplieron los criterios de inclusión y las variables seleccionadas para el estudio se recogieron de la historia clínica individual y familiar, en entrevista directa realizada al paciente para dar salida a los objetivos proyectados. Los datos obtenidos se llevaron a tablas de contingencia y fueron evaluados mediante tasas y razones de valoración porcentual acorde a la asociación las variables. Resultados: Predominó el grupo de edad de 50 a 60 años y, muy discretamente, el sexo masculino y el color de piel blanca. El riesgo cardiovascular bajo se comportó de igual manera en ambos sexos. El comportamiento de los factores de riesgos modificables estuvo a favor de los malos hábitos alimentarios, existió vínculo entre la intensidad del riesgo cardiovascular y la prevalencia del infarto del miocardio(AU)


Introduction: Noncommunicable diseases are the leading causes of death in Cuba. Among these, heart disease is a global health concern Objective: To identify the main cardiovascular risk factors for acute myocardial infarction in the population between aged 40-60 years. Methods: A descriptive, observational and cross-sectional research was carried out in the family medical office # 35 from Ciro Redondo neighborhood, belonging to Camilo Cienfuegos Polyclinic, San Cristóbal Municipality, Artemisa Province. The study universe was made up of 145 patients aged 40-60 years, residents of the rural community. The sample was made up of those who fulfilled the inclusion criteria, while the variables selected for the study were collected from the individual and family medical records, during direct patient interview, in order to fulfill the projected objectives. The obtained data were emptied into contingency tables and assessed through rates, ratios and percentages, according to the association of the variables. Results: The 50-60 age group predominated in the sample, with a slight predominance of males and patients of white skin. Low cardiovascular risk behaved in the same way in both sexes. The behavior of modifiable risk factors was consistent with poor eating habits. There was a link between the intensity of cardiovascular risk and the prevalence of myocardial infarction(AU)

ABSTRACT

Abstract Background Stroke and acute myocardial infarction (AMI) are cardiovascular diseases commonly characterized by the development of atheromatous plaques associated with major complications and high mortality rates. Objective To identify an epidemiological trend in hospitalizations due to stroke and AMI and to analyze the relationship between health programs applied in Primary Health Care, gender and the Federative Unit. Methods Ecological study with a time series design between 1998 and 2018, collecting data from all federal units in Brazil stratified by, gender and place of residence. There were analyzed Hospitalization Authorizations (AIH) for stroke and MI, consulting the Hospital Admissions System (SIH) of the Informatics Department of the National Health Service with p <0.05. Results From 1998 to 2018, the rate of hospitalization for AMI increased in Brazil approximately 42.58 events per 100 thousand inhabitants annually (p<0.001), while hospitalizations for stroke declined 32.17 cases (p=0.03). This pattern was observed in both sexes in AMI and stroke. There is also evidence of the effect of the Hiperdia (p<0.001) and Mais Médicos (p=0.001) program in reducing stroke and Hiperdia cases in mitigating the evolution of AMI cases (p = 0.0001). Conclusion Although these diseases remain as an important cause of death, stroke hospitalization has reduced significantly in the period evaluated. National programs as the Hiperdia and Mais Médicos showed an impact in the acute cases of strokes and AMI.

ABSTRACT

Los síndromes coronarios agudos sin lesiones coronarias han cobrado relevancia en los últimos años, pero aún no se dispone de datos locales. Analizamos un registro de pacientes con infarto agudo de miocardio, en 45 centros del país con residencias de cardiología. Se analizaron 1182 participantes de los cuales 33 (2.8%) no presentaron lesiones coronarias en angiografía, mientras que 89.5% tenían lesiones graves y 7.7% lesiones intermedias. La edad promedio de los pacientes sin lesiones coronarias fue 64.5 ± 13.0 años, 69.7% eran varones, sin diferencias respecto a aquellos con enfermedad epicárdica. La presentación electrocardiográfica más frecuente fue la desviación del segmento ST (13 supradesnivel y 10 infradesnivel del segmento). Además, este subgrupo presentó biomarcadores más bajos (CPK pico 203.5 UI/l, rango [RIC] 102- 422.5 vs. 895.5 UI/l RIC 350-1891, p < 0.0001). La mediana de días de internación fue 4.0 (RIC 3-5.5), siendo menor que la del grupo con enfermedad coronaria intermedia y grave (5.5 días, RIC 4-7, y 6 RIC 4-7, p = 0.003). Al alta, aquellos sin lesiones coronarias recibieron menor prescripción de IECA/ARA II (54.6% vs. 78.0% y 79.7%, p = 0.002) y estatinas (78.8% vs. 87.9% y 91.9%, p = 0.017). Ninguno de este subgrupo falleció durante la inter nación. Nuestros datos sugieren que los infartos sin lesiones coronarias significativas son frecuentes en nuestro medio, aunque probablemente se encuentren subdiagnosticados. Si bien su pronóstico parece más favorable, resulta importante señalar que recibieron menos fármacos para prevenir su recurrencia. Nuevos estudios son necesarios para profundizar el conocimiento de esta enfermedad.


Abstract Acute coronary syndromes without coronary lesions have gained relevance in recent years. However, local data on this condition is scarce. We aimed to explore this entity in a National registry of acute myocardial infarction that was carried out prospectively in hospitals with cardiology residence programs from Ar gentina. We included 1182 patients from 45 centers, where 33 did not present coronary lesions on angiography. The mean age was 64.5 ±13.0 and 69.7% were male, without differences compared to participants with epicardial disease. The most common electrocardiographic presentation was ST segment deviation. In addition, presented lower biomarkers (peak CPK 203.5 IU / l, range [IQR] 102-422.5 vs. 895.5 IU / l IQR 350-1891, p < 0.0001). The median hospitalization was 4.0 days (IQR 3-5.5), lower than the group with intermediate and severe coronary disease (5.5 days, RIC 4-7, and 6, RIC 4-7, p = 0.003). At discharge, less use of ACE/ARB (54.6% vs.78.0% y 79.7%, p = 0.002) and statins (78.8% vs. 87.9% y 91.9%, p = 0.017). No deaths during hospitalization were reported. Our data suggested that infarcts without significant coronary lesions are frequent, although they are probably underdiagnosed. Their prognosis seems to be more favorable, but they receive fewer drugs to prevent recurrence. New studies are necessary to deepen the knowledge of the disease.

ABSTRACT

ABSTRACT Background The coronavirus disease (COVID-19) pandemic affected the prompt diagnosis and treatment of Acute myocardial infarction (AMI). Aim: To characterize the clinical profile of patients with AMI during the COVID-19 pandemic, comparing them with a historical cohort. Material and Methods: A case-control study of 96 patients with AMI transferred to a high-volume percutaneous coronary intervention (PCI) hospital between March and July 2020, and a historical cohort of 269 patients transferred during the same period in 2019. Results: When comparing patients transferred during the pandemic with those of the historical cohort, the former were younger (63 ± 12 vs 68 ± 12 years, p 12 hours from the onset of symptoms (44 vs 0%, p < 0.01), a higher median door-to-device time (4 vs 3 hours, p < 0.01), a higher use of primary percutaneous coronary intervention (97 vs 71%, p < 0.01), and higher frequencies of cardiogenic shock (20 vs 4%, p < 0.01) and mechanical complications (10% vs 2%, p < 0.01). Patients during COVID pandemic had a higher thirty-day overall (20 vs 1.4%, p < 0.01) and cardiovascular mortality (13 vs 1%, p < 0.01). During the outbreak, 40% of patients had positive COVID-19 status, which was a predictor for thirty-day overall mortality (Risk ratio 2.90; 95% confidence intervals 1.14-7.36). Conclusions: During the pandemic patients with AMI exhibited delays in consultations and treatment, higher morbidity, and increased mortality. COVID-19 positivity was associated to worse thirty-day overall survival.


Antecedentes: La pandemia COVID-19 afectó el tratamiento oportuno del infarto agudo de miocardio (IAM). Objetivo: Caracterizar el perfil clínico de pacientes con IAM durante la pandemia COVID-19 y compararlos con una cohorte histórica. Pacientes y Métodos: Estudio caso-control de 96 pacientes con IAM transferidos a un hospital de alto volumen de intervención coronaria percutánea (ICP) entre marzo julio de 2020 y una cohorte histórica de 269 pacientes transferidos en el mismo período de 2019 (n = 269). Resultados: Al comparar los pacientes transferidos durante pandemia y la cohorte histórica, los primeros eran más jóvenes (63 ± 12 y 68 ± 12 años respectivamente, p 12 h desde iniciados síntomas de IAM con elevación ST (44,4 y 0% respectivamente, p < 0,01), una mediana de tiempo puerta-guía mayor (4 y 3 horas respectivamente, p < 0,01), un mayor uso de ICP primaria (97 y 71% respectivamente, p < 0,01), mayor frecuencia de shock cardiogénico (19,8 y 4,1% respectivamente, p < 0.01) y complicaciones mecánicas (10,4 y 1,7% respectivamente, p < 0,01). A treinta días, los primeros tuvieron mayor mortalidad general (19,8 y 1,4% respectivamente p < 0.01) y cardiovascular (12,5 y 1,4% respectivamente, p < 0,01). Durante la pandemia, 40% de los pacientes presentó positividad para COVID-19, siendo un factor predictivo de mortalidad general (razón de riesgo 2,90; intervalos de confianza 95% 1,14-7,36). Conclusiones: Durante la pandemia, hubo retrasos en tiempos de consulta y tratamiento y mayor morbimortalidad del IAM. La positividad de COVID-19 se asoció a peor sobrevida general a treinta días.

ABSTRACT

Background: There is no recent information on the incidence of acute myocardial infarction (AMI) in Chile. Aim: To describe and evaluate the temporal incidence trend of AMI in Chile between 2008 and 2016. Material and Methods: A time series study. We included all AMI cases (ICD10 = I21) that were registered in Chile between 2008 and 2016 in the national hospital discharge and death databases. Rates were stratified according to sex and age group. We calculated crude and standardized rates (direct method). Time trends were evaluated using Prais-Winsten (PW) regression models. Results: There were 132,784 cases of AMI. The mean age of cases was 67 ± 14 years, 67% were men. Crude and standardized rates were 84.4 and 73.1 cases per 100,000 inhabitants, respectively. Standardized incidence increased in total population and women, whose PW coefficients were 0.43 (0.01-0.82; p = 0.045) and 0.26 (0.005-0.47; p = 0.02), respectively. Regarding age, an upward trend was observed in the younger age groups, whose coefficients were 0.20 (0.08 − 0.31; p = 0.004) for cases < 45 years, 1.31 (0.81-1.81; p < 0.01) for cases between 45 and 54 years, and 2.68 (1.31 − 4.04; p = 0.002) for cases between 55 and 64 years. Conclusions: An increase in the number of cases with AMI was observed, especially in younger age groups. This estimation could be useful for planning and evaluating public policies.

ABSTRACT

Objective: This study aimed to compare the prevalence and trends of conventional risk factors for atherosclerotic cardiovascular disease(ASCVD) between young Chinese and American adults with first acute myocardial infarction. Methods: This was a retrospective cohort analysis. Hospitalized yang adults (aged from 18 to 44 years old) with first acute myocardial infarction(AMI) from January 2007 through December 2017 were identified from Beijing Anzhen hospital medical record system. Prevalence and trends of hypertension, diabetes mellitus, obesity, smoking, and dyslipidemia were analyzed and compared with young American adults, whose data were reported by Yandrapalli et al, and the hospitalizations for a first AMI in young adults aged 18 to 44 years were identified from national inpatient sample from January 2005 through September 2015. Results: Chinese cohort included 2 866 young adults with a first AMI (male, n=2 739, female, n=127), the mean age was (39±5) years. Presentation of AMI was more frequently ST-segment elevation myocardial infarction (77.3%, 2 214/2 866). American cohort included 280 875 subjects (male, n=203 700, female, n=77 175), the mean age was 39±5 years. Presentation of AMI was more frequently non-ST-segment elevation myocardial infarction (53.6%, 150 549/280 875). In China, dyslipidemia 2 254 (78.6%), smoking 2 084(72.7%), and hypertension 1 170 (40.8%) were most prevalent, and 96.0% (2 752/2 866) of patients had at least 1 risk factor; in the United States, smoking 159 537(56.8%), dyslipidemia 145 212 (51.7%), and hypertension 139 876 (49.8%) were most prevalent, and 90.3% (253 630/280 875) of patients had at least 1 risk factor. Women had a prevalence of diabetes was higher in women, and prevalence of dyslipidemia and smoking was higher in men in China (all P<0.05);prevalence of obesity, diabetes and hypertension was higher in Women, and prevalence of dyslipidemia and smoking was higher in man in the United States (all P<0.001). Prevalence of dyslipidemia and smoking was higher Chinese men (79.3% vs. 54.6%, 75.5% vs. 58.1%,all P<0.001), and prevalence of obesity, diabetes and hypertension was lower (13.1% vs. 18.6%, 14.9% vs. 19.9%, 40.6% vs. 49.3%, all P<0.001)in Chinses cohort than those in the United States cohort. Prevalence of smoking and obesity was lower (12.6% vs. 53.4%, 10.2% vs. 26.9%, all P<0.001) and prevalence of dyslipidemia was higher (63.8% vs. 44.1% P<0.001) in Chinese women than those in the United States women. Patients presenting with non-ST-segment elevation myocardial infarction had a higher prevalence of obesity, diabetes and hypertension than patients presenting with ST-segment elevation myocardial infarction in China (20.1% vs.10.9%, 17.6% vs. 14.5%, 47.4% vs. 38.9%, all P<0.05). The prevalence of the three risk factors also was higher in patients presenting with non-ST-segment elevation myocardial infarction in the US (24.0% vs.17.0%, 25.0% vs. 20.0%, 54.6% vs. 44.2%, all P<0.001), prevalence of smoking and dyslipidemia was lower in these patients (53.5% vs. 60.5%,51.4% vs. 52.1%, all P<0.001). The prevalence of hypertension and obesity increased and the rate of smoking reduced in China from 2007 through 2017 (all trend P<0.001). The prevalence of all these five conventional risk factors increased temporally in the United States from 2005 to 2015 (all trend P<0.001). The prevalence of hypertension increased by 15.6% in China and 14.5% in the United States, respectively, accounting the largest increase. Conclusions: Smoking, dyslipidemia, and hypertension are most prevalent in China and United State. Significant sex and AMI subtype difference are observed for individual risk factors. The prevalence of hypertension and obesity increased significantly over time in China and all these five conventional risk factors increased significantly in the United States.

ABSTRACT

Resumo Fundamento: O infarto agudo do miocárdio com supradesnivelamento do segmento ST (STEMI) é uma das principais apresentações clínicas da cardiopatia isquêmica. Dados de base populacional são relevantes para entendimento contemporâneo da epidemiologia da doença. Objetivo: Descrever incidência, manejo terapêutico, desfechos clínicos hospitalares e eventos cardiovasculares do primeiro ano de seguimento dos indivíduos hospitalizados por STEMI. Métodos: Estudo de coorte prospectiva de base populacional com registro consecutivo das hospitalizações por STEMI em uma cidade do Sul do Brasil entre 2011 e 2014. Foram incluídos indivíduos com STEMI que apresentaram sintomas de isquemia miocárdica aguda nas últimas 72 horas. Os valores de p < 0,05 foram considerados significativos. Resultados: A incidência anual de hospitalizações por STEMI foi de 108 casos por 100.000 habitantes. A incidência ajustada foi maior entre os mais velhos (risco relativo 64,9; IC95% 26,9 - 156,9; p para tendência linear < 0,001) e entre os homens (risco relativo 2,8; IC95% 2,3 - 3,3; p < 0,001). Ocorreram 530 hospitalizações durante o período avaliado e a taxa de reperfusão foi de 80,9%. A mortalidade hospitalar e a taxa de eventos cardiovasculares em 1 ano foram, respectivamente, 8,9% e 6,1%. Os mais velhos apresentaram maior mortalidade hospitalar (risco relativo 3,72; IC95% 1,57 - 8,82; p para tendência linear = 0,002) e mais eventos cardiovasculares em 1 ano (hazard ratio 2,35; IC95% 1,12 - 4,95; p = 0,03). Conclusão: Este registro demonstra abordagem terapêutica e mortalidade hospitalar semelhante às observadas em países desenvolvidos. Entretanto, a taxa de hospitalizações foi maior comparada com esses países.


Abstract Background: ST-segment elevation myocardial infarction (STEMI) is one of the main clinical manifestations of ischemic heart disease. Population-based data are relevant to better understand the current epidemiology of this condition. Objective: To describe the incidence, therapeutic management, hospital clinical outcomes and cardiovascular events in the first year of follow-up of individuals hospitalized for STEMI. Methods: Population-based prospective cohort study with consecutive registries of hospitalization for STEMI in a city in southern Brazil from 2011 to 2014. It included patients with STEMI who presented acute myocardial ischemia symptoms in the last 72 hours. A p-value < 0.05 was considered significant. Results: The annual incidence of STEMI hospitalizations was 108 cases per 100,000 inhabitants. Adjusted incidence was higher among older individuals (relative risk 64.9; 95% CI 26.9-156.9; p for linear trend < 0.001) and among men (relative risk 2.8; 95% CI 2.3-3.3; p < 0.001). There were 530 hospitalizations in the period under evaluation and the reperfusion rate reached 80.9%. Hospital mortality and the one-year follow-up cardiovascular event rate were, respectively, 8.9% and 6.1%. The oldest patients had higher hospital mortality (relative risk 3.72; 95% CI 1.57-8.82; p for linear trend = 0.002) and more one-year follow-up cardiovascular events (hazard ratio 2.35; 95% CI 1.12-4.95; p = 0.03). Conclusion: This study shows that both the therapeutic approach and hospital mortality are similar to the ones found in developed countries. However, the hospitalization rate was higher in these countries.

ABSTRACT

Abstract Objective: To analyze acute myocardial infarction (AMI) admissions and in-hospital mortality rates and evaluate the competence of the Ministry of Health (MOH) hospitals to provide AMI treatment. Materials and methods: We used a mixed-methods approach: 1) Joinpoint analysis of hospitalizations and in-hospital mortality trends between 2005 and 2017; 2) a nation-wide cross-sectional MOH hospital survey. Results: AMI hospitalizations are increasing among men and patients aged >60 years; women have higher mortality rates. The survey included 527 hospitals (2nd level =471; 3rd level =56). We identified insufficient competence to diagnose AMI (2nd level 37%, 3rd level 51%), perform pharmacological perfusion (2nd level 8.7%, 3rd level 26.8%), and mechanical reperfusion (2nd level 2.8%, 3rd level 17.9%). Conclusions: There are wide disparities in demand, supply, and health outcomes of AMI in Mexico. It is advisable to build up the competence with gender and age perspectives in order to diagnose and manage AMI and reduce AMI mortality effectively.


Resumen Objetivo: Analizar las tendencias de admisiones y mortalidad hospitalaria por infarto agudo al miocardio (IAM) y evaluar la competencia hospitalaria de la Secretaría de Salud (SS) para tratarlo. Material y métodos. Enfoque de métodos mixtos: Jointpoint análisis de tendencias de hospitalizaciones y mortalidad hospitalaria entre 2005 y 2017, y encuesta en hospitales de la SS. Resultados: Las hospitalizaciones por IAM están aumentando entre hombres y pacientes >60 años. Las mujeres tienen mayor mortalidad. La encuesta incluyó 527 hospitales (2º nivel =471, 3er nivel =56). Los hospitales tienen competencias insuficientes para diagnosticar IAM (2º nivel 37%, 3er nivel 51%), realizar perfusión farmacológica (2º nivel 8.7%, 3er nivel 26.8%) y reperfusión mecánica (2º nivel 2.8%, 3er nivel 17.9%). Conclusiones: Existen disparidades en demanda, oferta y resultados en salud del IAM. Es aconsejable fortalecer las competencias, con perspectivas de género y edad, para diagnosticar y tratar IAM, y reducir su mortalidad efectivamente.

ABSTRACT

Resumen Objetivo: Analizar el comportamiento de posibles causas predisponentes de muerte súbita (MS) intrahospitalaria luego de un infarto agudo de miocardio (IMA) en registros cubanos. Material y método: Se realizó una búsqueda de registros clínicos de pacientes con IMA en Cuba en las bases de datos de revistas nacionales, Scientific Library On-line (ScieLO) y Medline. Se priorizaron los artículos publicados desde 2016 para ser incluidos. Se definió como muerte súbita aquélla secundaria a arritmias ventriculares malignas (TV y FV), así como los pacientes con rotura cardíaca y actividad eléctrica sin pulso o asistolia como forma de presentación. Con posterioridad se evaluó la relación de este parámetro con la aparición de muerte súbita en 710 pacientes del Registro de Síndromes Coronarios Agudos (RESCUE). Resultados: En el contexto extrahospitalario, más de la mitad de las muertes súbitas cardíacas son secundarias a un infarto agudo de miocardio. En el hospital, la mortalidad en Cuba por IMA es homogénea. Sólo los centros con intervencionismo coronario escapan a este fenómeno. Aunque no del todo letales, las arritmias ventriculares malignas se relacionan con un peor pronóstico y su prevalencia no es homogénea en los registros revisados. Conclusiones: La muerte súbita luego de infarto agudo de miocardio será aún en Cuba una de las principales causas de muerte en los pacientes de fase aguda.


Abstract Objective: To analyze possible predisposing causes of in hospital sudden cardiac death (SCD) after an acute myocardial infarction (IMA) in Cuban registries. Material and methods: A search of clinical records of patients with IMA in Cuba was performed in the databases of national journals, Scientific Library On-line and Medline. Those articles published since 2016 were prioritized for inclusion. Sudden death is defined as that secondary to malignant ventricular arrhythmias (ventricular tachycardia, ventricular fibrillation) as well as patients with cardiac rupture with pulseless electrical activity or asystole as a form of presentation. Subsequently, the relationship of this parameter with the occurrence of sudden death was evaluated in 710 patients from the Registry of Acute Coronary Syndromes (RESCUE). Results: In the out-of-hospital setting, more than half of SCD are secondary to an IMA. Once in the hospital, mortality in Cuba from IMA is homogeneous. Only centers with coronary interventionism escape this phenomenon. Although not totally lethal, the presence of malignant ventricular arrhythmias is associated with a worse prognosis and its prevalence is not homogeneous in the reviewed records. Conclusions: Sudden death after IMA will continue to be one of the main causes of death of patients in the acute phase in Cuba.
