Reperfusion Strategies in Acute Myocardial Infarction: State of the Art

Abstract ST elevation myocardial infarction (STEMI) is a highly prevalent condition worldwide. Reperfusion therapy is strongly associated with the prognosis of STEMI and must be performed with a high standard of quality and without delay. A systematic review of different reperfusion strategies for STEMI was conducted, including randomized controlled trials that included major cardiovascular events (MACE), and systematic reviews in the last 5 years through the PRISMA ( Preferred Reporting Items for Systematic Reviews and Meta-Analysis) methodology. The research was done in the PubMed and Cochrane Central Register of Controlled Trials databases, in addition to a few manual searches. After the exclusion criteria were applied, 90 articles were selected for this review. Despite the reestablishment of IRA patency in PCI for STEMI, microvascular lesions occur in a significant proportion of these patients, which can compromise ventricular function and clinical course. Several therapeutic strategies - intracoronary administration of nicorandil, nitrates, melatonin, antioxidant drugs (quercetin, glutathione), anti-inflammatory substances (tocilizumab [an inhibitor of interleukin 6], inclacumab, P-selectin inhibitor), immunosuppressants (cyclosporine), erythropoietin and ischemic pre- and post-conditioning and stem cell therapy - have been tested to reduce reperfusion injury, ventricular remodeling and serious cardiovascular events, with heterogeneous results: These therapies need confirmation in larger studies to be implemented in clinical practice

Viabilidade miocárdica na prática clínica / Assessing myocardial viability in clinical practice

Embora a avaliação da viabilidade miocárdica seja comum na prática do cardiologista, muitos médicos têm dúvidas a respeito dos resultados dos métodos diagnósticos. A medicina nuclear tem papel importante nos estudos de viabilidade, mas os laudos precisam ser interpretados num contexto clínico e fisiopatológico. Este artigo teve o objetivo de revisar a origem e a evolução do conceito da viabilidade miocárdica. São expostos os métodos diagnósticos com ênfase na medicina nuclear com uma explicação funcional sobre cada tipo de exame. A partir disso, são mostradas imagens como exemplos e é proposta uma maneira de atuar nesses casos baseada na clínica, na porcentagem de miocárdio acometido e na topografia das lesões coronarianas (proximais ou distais). (AU)

Although assessing myocardial viability is a common cardiology practice, many physicians question the results of diagnostic methods. Nuclear medicine plays an important role in viability studies, but the reports require interpretation in a clinical and pathophysiological context. this article was aimed at reviewing the origin and evolution of myocardial viability. Here we present diagnostic methods by emphasizing nuclear medicine and provide a functional explanation of each test type using example images. We also propose how to act in these cases based on clinic examination findings, the percentage of affected myocardium, and coronary lesion topography (proximal or distal).(AU)

Complicaciones de la cirugía de revascularización coronaria en pacientes con diabetes mellitus de tipo II / Complications of the coronary revascularization surgery in patients with type II diabetes mellitus

Introducción: La diabetes mellitus y la cardiopatía isquémica están íntimamente relacionadas, puesto que los pacientes con la primera tienen más riesgo de presentar la segunda, así como mayor mortalidad cardiovascular. Objetivo: Identificar las complicaciones posoperatorias en pacientes con diabetes mellitus de tipo II. Método: Se realizó un estudio descriptivo de serie de casos de 203 pacientes con diabetes mellitus de tipo II, expuestos a cirugía de revascularización coronaria en el Cardiocentro del Hospital Provincial Docente Saturnino Lora de Santiago de Cuba, desde enero de 2011 hasta igual periodo de 2020. Resultados: En la casuística resultaron más afectados el sexo masculino (56,1 %) y el grupo etario de 45 - 64 años (53,7 %), quienes tenían más de 10 años con la enfermedad endocrina y se le había detectado la cardiopatía isquémica en el último, con una forma de presentación aguda. Se encontraron varios factores de riesgo, tales como enfermedad coronaria difusa, niveles de glucemia elevada en el periodo perioperatorio y fracción ventricular izquierda baja. En la mayoría de las intervenciones quirúrgicas se empleó la técnica de corazón latiendo (81,8 %), y las complicaciones predominantes fueron arritmias supraventriculares, bajo gasto cardiaco e infecciones de la herida. Conclusiones: La cirugía de coronaria en pacientes con diabetes mellitus de tipo II es el método que logra una revascularización más completa, tanto anatómica como funcional, y la técnica de corazón latiendo alcanza reducir la mortalidad, aunque aún son frecuentes las complicaciones atribuibles a causas multifactoriales.

Introduction: The diabetes mellitus and ischemic heart disease are closely related, since patients with the former have more risk of presenting the latter, as well as higher cardiovascular mortality. Objective: To identify the postoperative complications in patients with type II diabetes mellitus. Method: A serial cases descriptive study of 203 patients with type II diabetes mellitus, exposed to coronary revascularization surgery was carried out in the Heart Center of Saturnino Lora Teaching Provincial Hospital Hospital in Santiago de Cuba, from January, 2011 to the same period in 2020. Results: In the case material the male sex (56.1 %) and the 45 - 64 age group (53.7 %) were more affected, who had more than 10 years with the endocrine disease and the ischemic heart disease had been detected in the latter, with an acute form of presentation. Several risk factors were found, such as diffuse coronary disease, glycemia high levels in the perioperative period and low left ventricular fraction. In most of the surgical interventions the heart beating technique was used (81.8 %), and the predominant complications were supraventricular arrhythmias, low heart output and infections of the wound. Conclusions: The surgery of coronary in patients with type II diabetes mellitus is the method that achieves a more complete revascularization, either anatomical as functional, and the heart beating technique reduces the mortality, although the complications attributable to multifactorial causes are still frequent.

Transfusion of Blood Products in the Postoperative of Cardiac Surgery

Abstract Background: The indiscriminate use of blood transfusion in surgery has been associated with increased risk of infection and increased length of hospital stay. Objective: To identify the average amount of bleeding and rates of transfusion of blood products in the postoperative period of patients undergoing cardiac surgery in a cardiology center. Methods: Medical records of patients who underwent myocardial revascularization surgery and/or heart valve replacement with use of cardiopulmonary bypass (CPB) were analyzed. Perioperative data such as CPB time, hematocrit and hemoglobin values were collected after surgery. The amount of bleeding (mL), blood transfusion (IU), clinical complications and time of hospitalization were also recorded. The correlation between bleeding in the postoperative period and blood transfusion was performed using the Spearman correlation. A p < 0.05 was considered statistically significant. Results: A total of 423 patients undergoing coronary artery bypass grafting (51.5%) or heart valve replacement (33.6%) were included. During the first 24 hours, the average bleeding volume was 353.3 ± 268.3 mL. Transfusion of blood products was required in 40.1% of cases, most frequently (70.6%) in the immediate postoperative period. Red blood cell concentrate was the most frequently used product (22.9% and 60%). Conclusion: The occurrence of bleeding in the cases was low, and when transfusion of blood components was indicated, red blood cell concentrates were the most widely used component.

Patients Submitted to Myocardial Revascularization with the Use of Bilateral Internal Thoracic Arteries: Diabetics vs. Non-Diabetics

Abstract Introduction: Use of bilateral internal thoracic artery (BITA) as graft in coronary artery bypass grafting (CABG) is controversial because it is related to higher in-hospital mortality, incidence of sternal wound-related infection, and an increase in surgical time. The primary objective of this study is to evaluate in-hospital mortality and mortality within 30 days from discharge. The secondary objective is to evaluate the occurrence of deep sternal wound infection in a 90-day follow-up. Methods: This is a retrospective review of the medical records of 152 patients undergoing elective CABG with the use of BITA and cardiopulmonary bypass (CPB). These patients were divided into two groups, diabetics and non-diabetics. Patients with acute myocardial infarction and concomitant valvular disease were not included in the sample. Results: Preoperative characteristics did not show significant differences between the groups, which allowed a comparative analysis. The variables electrocardiography time and aortic clamping time were higher in the diabetic group, with a significant statistical difference (P<0.0001). In-hospital mortality occurred in three patients, and there was no mortality up to 30 days in both groups. There was no significant difference in the primary end point between groups (P=0.56). Deep sternal wound infection was present in only one patient and showed no significant difference in the secondary outcome between groups (P=0.40). Conclusion: We did not observe a higher mortality and occurrence of deep sternal wound infection with the use of BITA in diabetic patients compared to non-diabetics, even with greater CPB and aortic clamping times in diabetics.

Two types of inspiratory muscle training on muscle strength in patients submitted to coronary artery bypass grafting: clinical trial / Dois tipos de treinamento muscular inspiratório sobre a força muscular de pacientes após revascularização do miocárdio: ensaio clínico

Introduction: Coronary artery bypass grafting (CABG) causes changes in the respiratory musculature that affects functional capacity and postoperative complications (POC). Inspiratory muscle training (IMT) is a tool used for these patients, but it is not known what the best form is to increase strength. Objective: To investigate whether IMT with a linear pressure load device is superior to the inspiratory incentive on functional capacity and muscle strength of patients undergoing CABG. Methods: This is a clinical trial. Patients were assessed preoperatively for inspiratory muscle pressure (MIP), expiratory pressure (MEP), peak expiratory flow (PEF), six-minute walk test (6MWT) and functional independence measure (FIM). After surgery, they were divided into three groups: control group (CG), training group with linear pressure load (IMT) and inspiratory incentive group (IG). On the day of discharge, all patients had their previous variables reassessed. Results: The study included 56 patients, 31 (55.4%) were male and an average age of 55 ± 12 years. There was a significant reduction in all variables, in relation to MIP, the IMT showed a higher value in the postoperative period 83 ± 19 cmH2O, against 70 ± 15 cmH2O in the CG and 80 ± 15 cmH2O in the IG (p < 0.001). The same behavior was observed in MEP, 77 ± 12 cm H2O in IMT, 67 ± 14 cmH2O in CG and 75 ± 10 cmH2O in IG (p < 0.001). Regarding the 6 MWT, there was a lesser loss in the IMT from 434 ± 15 m to 398 ± 20 m in IG (p < 0.001). Conclusion: It is concluded that muscle training with a linear pressure load device is superior to training with incentive on functional capacity and muscle strength in patients undergoing CABG.

Introdução: A cirurgia de revascularização do miocárdio (CRM) causa alterações na musculatura respiratória que afetam a capacidade funcional e complicações pós-operatórias (DCP). O treinamento muscular inspiratório (TMI) é uma ferramenta utilizada por esses pacientes, mas não se sabe qual é a melhor forma de aumentar a força. Objetivo: Investigar se o TMI com dispositivo de carga de pressão linear é superior ao incentivo inspiratório na capacidade funcional e força muscular de pacientes submetidos à CRM. Métodos: Este é um ensaio clínico. Os pacientes foram avaliados no pré-operatório para pressão muscular inspiratória (PImáx), pressão expiratória (PEF), pico de fluxo expiratório (PFE), teste de caminhada de seis minutos (TC6) e medida de independência funcional (MIF). Após a cirurgia, eles foram divididos em três grupos: grupo controle (GC), grupo treinamento com carga linear de pressão (IMT) e grupo incentivo inspiratório (GI). No dia da alta, todos os pacientes tiveram suas variáveis anteriores reavaliadas. Resultados: O estudo incluiu 56 pacientes, 31 (55,4%) eram do sexo masculino e idade média de 55 ± 12 anos. Houve redução significativa em todas as variáveis, em relação à PImáx, o IMT apresentou valor maior no pós-operatório 83 ± 19 cmH2O, contra 70 ± 15 cmH2O no GC e 80 ± 15 cmH2O no GI (p < 0,001). O mesmo comportamento foi observado na PEmáx, 77 ± 12 cmH2O no IMT, 67 ± 14 cmH2O no GC e 75 ± 10 cmH2O no GI (p < 0,001). Em relação ao TC6, houve menor perda no TMI de 434 ± 15 metros para 398 ± 20 metros no GI (p < 0,001). Conclusão: Conclui-se que o treinamento muscular com dispositivo de carga pressórica linear é superior ao treinamento com incentivo inspiratório na capacidade funcional e da força muscular em pacientes submetidos à CRM.

Risk Score for Prolonged Mechanical Ventilation in Coronary Artery Bypass Grafting

Abstract Background Prolonged mechanical ventilation (MV) after cardiac surgery imposes a significant burden on the patient in terms of morbidity and financial hospital costs. Objective To develop a risk score model to predict prolonged MV in patients undergoing coronary artery bypass grafting (CABG) surgery. Methods This was a historical cohort study of 4165 adult patients undergoing CABG between January 1996 and December 2016. MV for periods ≥ 12 hours was considered prolonged. Logistic regression was used to examine the relationship between risk predictors and prolonged MV. The variables were scored according to the odds ratio. To build the risk score, the database was randomly divided into 2 parts: development data set (2/3) with 2746 patients and internal validation data set (1/3) with 1419 patients. The final score was validated in the total database and the model's accuracy was tested by performance statistics. Significance was established at p < 0.05. Results Prolonged MV was observed in 783 (18.8%) patients. Predictors of risk were age ≥ 65 years, urgent/emergency surgery, body mass index ≥ 30 kg/m2, chronic kidney disease, chronic obstructive pulmonary disease, and cardiopulmonary bypass time ≥ 120 minutes. The area under the ROC curve was 0.66 (95% CI, 0.64-0.68; p<0.001), the Hosmer-Lemeshow chi-square test was χ2: 3.38 (p=0.642), and Pearson's correlation was r = 0.99 (p<0.001), indicating the model's satisfactory ability to predict the occurrence of prolonged MV. Conclusion Selected variables allowed the construction of a simplified risk score for daily practice, which may classify the patients as having low, moderate, high, and very high risk.

Correlation between Surgical Risk Scales with Respiratory Muscle Strength and Functional Independence in Patients Submitted to Coronary Artery Bypass Grafting

Abstract Background The European Heart Surgery Risk Assessment System (EuroSCORE) and InsCor have been used to predict complications of cardiac surgery. However, their application to predict lung function and functionality is still uncertain. Objective To correlate surgical risk scales with functional independence and pulmonary function in patients undergoing coronary artery bypass grafting. Methods This was a prospective cohort study. In the preoperative period, the two surgical scales were applied, the maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and peak expiratory flow (PEF) were measured, and functionality was assessed using the functional independence measure (FIM). On the seventh postoperative day, the pulmonary function and functionality variables were reevaluated, compared with the preoperative values (delta) and correlated with the risk scales. Correlations of pulmonary function, functional independence and muscle strength variables with the surgical scales were made by Pearson correlation test. The significance level adopted was 5%. Results Thirty-one patients were studied; most were male (77%), with a mean age of 56±8 years. Mean EuroSCORE was 2.3±0.5 and mean InsCOR was 1.2±0.5. MIP, MEP, and PEF reduced 30% (p<0.001), 33% (p<0.001) and 10% (p=0.23), respectively. The EuroSCORE correlated with MIP (r-0.78; p = 0.02) and FIM (r-0.79; p <0.01), and the InsCor correlated with MIP (r-0.77), MEP (r-0.73) and MIF (r-0.89; p=0.02). Conclusion The EuroSCORE showed a strong negative correlation with MIP and FIM, while InsCor had a strong negative correlation with MIP, MEP and FIM.

Respiratory mechanics behavior after heart surgery: an experimental study

Changes in ventilatorymechanics and their consequent pulmonary complications are common after surgical procedures, particularly in cardiac surgery (CS), and may be associated with both preoperative history and surgical circumstances. This study aims to compare ventilatory mechanics in the moments before and after cardiac surgery (CS), describing how pulmonary complications occurred. An experimental, uncontrolled study was conducted, of the before-and-after type, and with a descriptive and analytical character. It was carried out in a private hospital in the city of Salvador, Bahia, Brazil, and involved 30 adult patients subjected to CS. In addition to clinical and epidemiological variables, minute volume (VE), respiratory rate (RR), tidal volume (VT), forced vital capacity (FVC), maximum inspiratory pressure (MIP), and peak expiratory flow (PEF) were also recorded. Data were collected in the following moments: preoperative (PRE-OP) period, immediate postoperative (IPO) period, and 1stpostoperative day (1stPOD). The sample was aged 48.1 ± 11.8 years old and had a body mass index of 25.5 ± 4.9 kg m-2; 60% of the patients remained on mechanical ventilation for less than 24 hours (17.5 [8.7-22.9] hours). There was a significant reduction in VT, FVC, MIP and PEF when PRE-OP versus IPO, and PRE-OP versus 1stPOD were compared (p < 0.05). There were no significant changes between IPO and the 1stPOD. The highest incidence of pulmonary complications involved pleural effusion (50% of the patients). This study showed that patients subjected to CS present significant damage to ventilatory parameters after the surgery, especially in the IPO period and on the 1stPOD. It is possible that the extension of this ventilatory impairment has led to the onset of postoperative pulmonary complications.

Factores determinantes en la calidad de vida de pacientes con enfermedad coronaria sometidos a diferentes intervenciones terapéuticas / Determinants in quality of life of patients with coronary artery disease who underwent different therapeutic interventions

Resumen Introducción: La enfermedad coronaria es la principal causa de mortalidad en el mundo. Su tratamiento se asocia con una mejor calidad de vida, la cual puede medirse con el cuestionario de MacNew. Objetivo: Establecer los factores determinantes de calidad de vida en pacientes con enfermedad coronaria. Materiales y métodos: Estudio analítico de corte transversal, en el que se usó el cuestionario de MacNew para valorar la calidad de vida en tres dominios: social, emocional y físico. Se incluyeron 249 pacientes con enfermedad coronaria diagnosticada en los años 2004, 2009 o 2013. Los resultados se estratificaron por el tipo de tratamiento (médico, implantación de stent o cirugía de revascularización miocárdica). Se usó un modelo de regresión beta, como una alternativa al modelo de regresión lineal. Resultados: Los puntajes más bajos se asociaron con hipertensión arterial, diabetes mellitus, dislipidemia y aumento del índice de masa corporal. En el dominio físico el puntaje disminuyó en los pacientes mayores de 60 años. El alto grado de escolaridad se asoció con mayores puntajes en todos los dominios. Conclusiones: Los pacientes con enfermedad coronaria presentaron menor calidad de vida asociada a hipertensión arterial, diabetes mellitus, dislipidemia, aumento del índice de masa corporal o mayor edad y mejor calidad de vida asociada con mayor nivel de escolaridad y afiliación al sistema de salud, indiferente a la intervención terapéutica.

Abstract Introduction: Coronary heart disease is the leading cause of mortality worldwide. Its treatment is associated with a better quality of life; it can be measured with the MacNew questionnaire. This study aims to establish the determin. Objective: To stablish the determinants of quality of life in coronary heart disease patients, in Cali, Colombia. Materials and methods: Analytical cross-sectional study, in which the MacNew questionnaire was applied to assess life quality in three domains: social, emotional and physical. 249 patients with coronary heart disease diagnosed in 2004, 2009 or 2013 were included. The results were stratified by type of treatment (doctor, stent implantation or myocardial revascularization surgery). Beta regression model was used, as an alternative to the linear regression model. Results: The MacNew lower scores were associated with hypertension, diabetes mellitus, dyslipidemia and increased body mass index. In the physical domain, the life quality score decreased in patients older than 60 years. High levels of education were associated with higher quality of life scores in all domains. Conclusions: Coronary heart disease patients presented lower quality of life associated with hypertension, diabetes mellitus, dyslipidemia, increased body mass index or older age and better quality of life associated with higher level of education and affiliation to the health system, regardless of the therapeutic intervention received.

Efecto de una intervención educativa de enfermería para reducir el dolor en el paciente con revascularización miocárdica durante el posoperatorio ambulatorio / Effect of an educational nursing intervention to reduce pain in patients with myocardial revascularization during the outpatient postoperative period

Introducción: Las necesidades que experimentan los pacientes en el postoperatorio de cirugía cardiaca van desde lo fisiológico hasta la esfera emocional. A nivel fisiológico el dolor es una necesidad insatisfecha, que repercute en otras necesidades como el sueño y la actividad física, el estado de ánimo, la adherencia terapéutica y la calidad de vida. Objetivo: Determinar el efecto de una intervención educativa de Enfermería comparada con el cuidado de enfermería convencional, para reducir el dolor del paciente de cirugía cardiaca en el posoperatorio ambulatorio en una Institución de alta complejidad en Cúcuta durante el II semestre del año 2020 y el I semestre del año 2021. Metodología: Estudio cuantitativo, cuasi experimental, con medición preprueba en el control posoperatorio realizado al tercer día y posprueba, con grupo de comparación, en pacientes con revascularización miocárdica de una institución de alta complejidad en Cúcuta, con muestreo probabilístico, aleatorio simple, con una muestra estimada de 40 pacientes para cada grupo. Para la recolección de la información se utilizó el cuestionario del dolor McGill (índice de valoración del dolor) (Cibersam, 1994) y el Inventario de la Ansiedad Rasgo, IDARE, previo diligenciamiento del consentimiento informado, se realizaron mediciones del dolor al tercer día de posoperatorio ambulatorio, a los 15 y 30 días de entrega de la intervención educativa, para determinar el efecto de la intervención entre grupos e intragrupo frente al cuidado convencional. Resultados: El grupo experimental exhibió una reducción estadísticamente significativa de los niveles del dolor para cada una de las dimensiones y a nivel general luego de la intervención educativa (p< 0.05) mientras que en el grupo de comparación no hubo cambios importantes en los niveles de dolor entre ambas mediciones (p > 0.05). También se pudo establecer que el grupo experimental exhibió una reducción estadísticamente significativa de los niveles de ansiedad para cada una de las dimensiones y a nivel general luego de la intervención educativa (p< 0.05) contrario al grupo de comparación, donde se evidenció un aumento en el nivel de ansiedad, aunque sin diferencias importantes respecto de la medición inicial (p > 0.05).
