Cardiovascular Complications in Patients with Heart Failure and COVID-19: CARDIO COVID 19-20 Registry.

Since early 2020, different studies have shown an increased prevalence of COVID-19 and poorer prognosis in older adults with cardiovascular comorbidities. This study aimed to assess the impact of heart failure (HF) on cardiovascular complications, intensive care unit (ICU) admissions, and in-hospital mortality in patients hospitalized with COVID-19. The CARDIO COVID 19-20 registry includes 3260 hospitalized patients with a COVID-19 serological diagnosis between May 2020 and June 2021 from Latin American countries. A history of HF was identified in 182 patients (5.6%). In patients with and without previous HF, the incidence of supraventricular arrhythmia was 16.5% vs. 6.3%, respectively (p = 0.001), and that of acute coronary syndrome was 7.1% vs. 2.7%, respectively (p = 0.001). Patients with a history of HF had higher rates of ICU admission (61.5% vs. 53.1%, respectively; p = 0.031) and in-hospital mortality (41.8% vs. 24.5%, respectively; p = 0.001) than patients without HF. Cardiovascular mortality at discharge (42.1% vs. 18.5%, respectively; p < 0.001) and at 30 days post-discharge (66.7% vs. 18.0%, respectively) was higher for patients with a history of HF than for patients without HF. In patients hospitalized with COVID-19, previous history of HF was associated with a more severe cardiovascular profile, with increased risk of cardiovascular complications, and poor in-hospital and 30-day outcomes.

Latin-American Registry of Cardiovascular Disease and COVID-19: Final Results.

Background: Socioeconomic factors contribute to a more severe impact of COVID-19 in Latin American and Caribbean (LA&C) countries than in developed countries. Patients with a severe or critical illness can develop respiratory and cardiovascular complications. Objective: To describe a LA&C population with COVID-19 to provide information related to this disease, in-hospital cardiovascular complications, and in-hospital mortality. Methods: The CARDIO COVID-19-20 Registry is an observational, multicenter, prospective, and hospital-based registry of patients with confirmed COVID-19 infection that required in-hospital treatment in LA&C. Enrollment of patients started on May 01, 2020, and ended on June 30, 2021. Results: The CARDIO COVID-19-20 Registry included 3260 patients from 44 institutions of 14 LA&C countries. 63.2% patients were male and median age was 61.0 years old. Most common comorbidities were overweight/obesity (49.7%), hypertension (49.0%), and diabetes mellitus (26.7%). Most frequent cardiovascular complications during hospitalization or reported at discharge were cardiac arrhythmia (9.1%), decompensated heart failure (8.5%), and pulmonary embolism (3.9%). The number of patients admitted to the Intensive Care Unit (ICU) was 1745 (53.5%), and median length of their stay at the ICU was 10.0 days. Support required in ICU included invasive mechanical ventilation (34.2%), vasopressors (27.6%), inotropics (10.3%), and vasodilators (3.7%). Rehospitalization after 30-day post discharge was 7.3%. In-hospital mortality and 30-day post discharge were 25.5% and 2.6%, respectively. Conclusions: According to our findings, more than half of the LA&C population with COVID-19 assessed required management in ICU, with higher requirement of invasive mechanical ventilation and vasoactive support, resulting in a high in-hospital mortality and a considerable high 30-day post discharge rehospitalization and mortality.

Latin-American Registry of Cardiovascular Disease and COVID-19: Rationale and Design of the CARDIO COVID 19-20 Registry.

Background: Infection caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) exhibits a strong infectivity but less virulence compared to severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). In terms of cardiovascular morbidity, susceptible population include elderly and patients with certain cardiovascular conditions. This infection has been associated with cardiac injury, cardiovascular complications and higher mortality. Objectives: The main objective of the CARDIO COVID 19-20 Registry is to determine the presence of cardiovascular comorbidities and cardiovascular complications in COVID-19 infected patients that required in-hospital treatment in different Latin American institutions. Methods: The CARDIO COVID 19-20 Registry is an observational, multicenter, ambispective, and hospital-based registry of patients with confirmed COVID-19 infection who required in-hospital treatment in Latin America. Enrollment of patients started on May 01, 2020 and was initially planned to last three months; based on the progression of pandemic in Latin America, enrollment was extended until December 2020, and could be extended once again based on the pandemic course in our continent at that moment. Conclusions: The CARDIO COVID 19-20 Registry will characterize the in-hospital population diagnosed with COVID-19 in Latin America in order to identify risk factors for worsening of cardiovascular comorbidities or for the appearance of cardiovascular complications during hospitalization and during the 30-day follow up period.

[Diabetes and Heart Failure]. / Diabetes e Insuficiencia Cardíaca.

Diabetes Mellitus (DM) is a chronic non-communicable cardio-metabolic disease that causes macro-vascular complications such as atherosclerosis, coronary disease and heart failure (HF). There is a bidirectional relationship between HF and DM, HF being the second most frequent initial cardiovascular event in patients with diabetes. It may even be the first cardiovascular complication, before acute myocardial infarction. DM can lead to HF through mechanisms mediated by atherosclerosis and non mediated by it. In the first case, cholesterol is deposited in coronary arteries, favored by the presence of other risk factors. In the second case, the myocardium is directly affected leading to structural and functional changes through non-atherogenic mechanisms (called Diabetic Cardiomyopathy). The treatment of HF with reduced ejection fraction in the diabetic patient does not differ from that of the non-diabetic population, the triple neurohumoral block must be achieved. In the case of patients with HF with ejection fraction preserved to date, we do not have specific therapy to reduce cardiovascular morbidity and mortality. In the diabetes treatment of the patient with HF, sodium-glucose type 2 cotransporter inhibitors (SGLT2i) clearly stand out. In addition to their glucosuric and natriuretic effect, they have pleiotropic effects that produce metabolic, hemodynamic and cellular viability effects preventing apoptosis and cell death. Finally, the clinical benefits of SGLT2 inhibitors in HF go beyond glycemic control, as demonstrated by the DAPA-HF study; initiating a new era in the treatment of patients with HF with reduced ejection fraction.

OBJETIVE.: To describe the histopathological characteristics of explanted hearts and post-transplant biopsy specimens at a national reference center in Peru. MATERIALS AND METHODS.: A case series study of patients who underwent heart transplantation between March 2010 and February 2018. RESULTS.: Sixty-one (61) transplanted patients with a mean age of 40.1 years (range: 9-66 years). Five cases (8.2%) initially diagnosed as dilated cardiomyopathy were reclassified after the histopathological study. The three leading causes of primary disease after transplantation were: idiopathic dilated cardiomyopathy (50.8%), ischemic cardiomyopathy (16.4%), and valvular cardiomyopathy (6.6%). The mean follow-up was 2.8 years. The post-transplant survival rate was 85.1% at 1 year and 82.8% at 5 years. Moderate/severe acute cellular rejection occurred in 12 patients (21.1%) and antibody-mediated rejection occurred in 3 patients (5.3%). CONCLUSIONS.: Routine histopathological evaluation of the explanted heart is essential to confirm the etiology of heart failure, especially in cases clinically diagnosed as dilated cardiomyopathy. In addition, routine follow-up through endomyocardial biopsies shows that acute cellular rejection is still a frequent complication after a heart transplant, especially within the first year, and that antibody-mediated rejection has a low incidence in our population.

OBJETIVOS: Describir las características histopatológicas de los explantes cardiacos y las biopsias endomiocárdicas postrasplante realizadas en un centro de referencia nacional del Perú. MATERIALES Y MÉTODOS.: Estudio de una serie de casos de pacientes sometidos a trasplante cardiaco entre marzo de 2010 y febrero de 2018. RESULTADOS.: Los 61 pacientes trasplantados, tuvieron un promedio de edad de 40,1 (rango: 9-66 años). Cinco casos (8,2%) diagnosticados inicialmente como miocardiopatía dilatada fueron reclasificados después del estudio histopatológico. Las tres primeras causas de enfermedad primaria previa al trasplante fueron: miocardiopatía dilatada idiopática (50,8%), cardiopatía isquémica (16,4%), y cardiopatía valvular (6,6%). El seguimiento promedio fue de 2,8 años. La tasa de supervivencia después del trasplante fue del 85,1% al año y del 82,8% a los cinco años. El rechazo celular agudo moderado/severo ocurrió en 12 pacientes (21,1%) y el rechazo mediado por anticuerpos ocurrió en tres pacientes (5,3%). CONCLUSIONES.: La evaluación histopatológica rutinaria del explante cardiaco es esencial para confirmar la etiología de la insuficiencia cardíaca, especialmente en los casos diagnosticados clínicamente como miocardiopatía dilatada. Asimismo, el seguimiento rutinario mediante biopsias endomiocárdicas muestra que el rechazo celular agudo continúa siendo una complicación frecuente durante el primer año de trasplante, y que el rechazo mediado por anticuerpos tiene una baja frecuencia en nuestra población.
