ABSTRACT
AIMS: Heart failure (HF) is a highly prevalent and progressive condition associated with significant morbidity and mortality rates. Acute decompensated HF precipitates millions of hospitalizations each year. Despite therapeutic advances, the overall prognosis of HF is poor. The varying clinical courses and outcomes of patients with this disease may be due to region-specific gaps and since most HF studies are conducted in developed countries, the participation of Latin American and Caribbean countries is low. Considering this, the American Registry of Ambulatory and Acute Decompensated Heart Failure (AMERICCAASS) aims to characterize the population with ambulatory and acute decompensated HF in the American continent and to determine rehospitalization and survival outcomes during the 12 months of follow-up. METHODS AND RESULTS: AMERICCAASS Registry is an observational, prospective, and hospital-based registry recruiting patients with ambulatory or acute decompensated HF. The registry plans to include between two and four institutions per country from at least 20 countries in the Americas, and at least 60 patients recruited from each participant institution regardless of their ambulatory or acutely decompensated condition. Ambulatory patients with confirmed HF diagnosis or inpatients presenting with acute decompensated HF will be included. Follow-up will be performed at 12 months in ambulatory patients or 1, 6, and 12 months after hospital discharge in acutely decompensated HF patients. This ongoing study began on 1 April 2022, with recruitment scheduled to end on 30 November 2023, and follow-up on 31 January 2025. Ethics approval was obtained from the Biomedical Research Ethics Committee of Fundación Valle del Lili. Data collected in the AMERICCAASS registry is being stored on the electronic platform REDCap (Research Electronic Data Capture), which allows different forms for patient groups to enable unbiased analyses. For quantitative variables comparison, we will use the Student's t-test or non-parametric tests accordingly. Categorical variables will be presented as proportions, and groups will be compared with Fisher's exact test. The significance level will be <0.05 for comparisons. Readmissions and post-discharge mortality will be calculated as proportions at 1, 6, and 12 months, with a survival analysis by conditional probability and the Kaplan-Meier method. CONCLUSIONS: AMERICCAASS Registry is intended to be the most important registry of the continent for obtaining important information about demographics, aetiology, co-morbidities, and treatment received, either ambulatory or hospitalized. This registry may contribute to the optimization of national and regional evidence and public policies for the diagnosis and treatment of HF disease.
ABSTRACT
BACKGROUND: The COVID-19 pandemic has highlighted a correlation between cardiac complications and elevated cardiac biomarkers, which are linked to poorer clinical outcomes. OBJECTIVE: This study aims to determine the clinical impact of cardiac biomarkers in COVID-19 patients in Latin America. SUBJECTS AND METHODS: The CARDIO COVID 19-20 Registry is a multicenter observational study across 44 hospitals in Latin America and the Caribbean. It included hospitalized COVID-19 patients (n = 476) who underwent troponin, natriuretic peptide, and D-dimer tests. Patients were grouped based on the number of positive biomarkers. RESULTS: Among the 476 patients tested, 139 had one positive biomarker (Group C), 190 had two (Group B), 118 had three (Group A), and 29 had none (Group D). A directly proportional relationship was observed between the number of positive biomarkers and the incidence of decompensated heart failure. Similarly, there was a proportional relationship between the number of positive biomarkers and increased mortality. In Group B, patients with elevated troponin and natriuretic peptide and those with elevated troponin and D-dimer had 1.4 and 1.5 times higher mortality, respectively, than those with elevated natriuretic peptide and D-dimer. CONCLUSIONS: In Latin American COVID-19 patients, a higher number of positive cardiac biomarkers is associated with increased cardiovascular complications and mortality. These findings suggest that cardiac biomarkers should be utilized to guide acute-phase treatment strategies.
ABSTRACT
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.
ABSTRACT
Heart failure (HF) is a significant event for public health. It has a prevalence between 1-2%, mortality rate between 7-17%, and hospitalization between 32-44%. This implies a risk to health and quality of life, but also great financial efforts for health systems. Sacubitril/valsartan is a medication recognized for its efficacy, and this consensus seeks to synthesize the available information regarding its use for the benefit of patients. This document consists of a description of the epidemiology of HF, pharmacology of the drug, clinical trials, use of the drug in cases with reduced ejection fraction, mildly reduced ejection fraction and preserved ejection fraction, available literature on HF guidelines, recommendations and conclusions.
La insuficiencia cardiaca (IC) es un evento significativo para la salud pública. Tiene una prevalencia entre el 1 y 2%, tasa de mortalidad entre el 7 y 17% y de hospitalización entre el 32 y 44%. Esto implica un riesgo a la salud y calidad de vida, pero también grandes esfuerzos financieros para los sistemas de salud. El sacubitrilo/valsartán es un medicamento reconocido por su eficacia, y este consenso busca sintetizar la información disponible respecto a su uso en búsqueda del beneficio de los pacientes. El presente documento se compone de una descripción de la epidemiología de la IC, farmacología del medicamento, estudios clínicos sobre este, uso del medicamento en casos con fracción de eyección reducida, fracción de eyección ligeramente reducida y fracción de eyección preservada, literatura disponible en guías de IC, recomendaciones y conclusiones.

BACKGROUND: Patients with a cardiovascular (CV) history may be at greater risk of becoming ill and die due to SARS-CoV-2. AIM: To assess the incidence of CV complications in COVID-19 patients, the type of complication, and their association with CV history. MATERIAL AND METHODS: The clinical course of 1,314 patients with COVID-19 admitted consecutively to critical care units of 10 Chilean hospitals was registered between April and August of 2020. RESULTS: The median age of patients was 59 years and 66% were men. One hundred-four (8%) had a CV history, namely heart failure (HF) in 53 (4.1%), coronary heart disease in 50 (3.8 %), and atrial fibrillation in 36 (2.7 %). There were CV complications in 359 patients (27.3%). The most common were venous thrombosis in 10.7% and arrhythmias in 10.5%, HF in 7.2%, type 2 acute myocardial infarction in 4.2%, arterial thrombosis in 2.0% and acute coronary syndrome (ACS) in 1.6%. When adjusted by age, sex and risk factors, only HF (Odds ratio (OR) = 7.16; 95% confidence intervals (CI), 3.96-12.92) and ACS (OR = 5.44; 95% CI, 1.50-19.82) were significantly associated with CV history. There was no association with arrhythmias, type 2 acute myocardial infarction, arterial or venous thrombosis. CONCLUSIONS: Patients with a history of CV disease are at greater risk of suffering HF and ACS when hospitalized due to COVID-19. Arrhythmias, type 2 AMI, and arterial or venous thrombosis occur with the same frequency in patients with or without CV history, suggesting that these complications depend on inflammatory phenomena related to the infection.

Spontaneous coronary artery dissection is an uncommon cause of acute coronary syndrome that predominantly affects women without cardiovascular risk factors. In transplant patients, spontaneous coronary artery dissection is an extremely rare condition, having been described in only three patients, in whom vascular damage secondary to the use of anticalcineurinics is postulated as a probable mechanism. We report a spontaneous coronary dissection in a female who received a heart transplant at 34 years of age. The diagnosis was made in a follow-up coronary angiography three years after transplantation, supplemented with optical coherence tomography. A percutaneous coronary revascularization of the involved artery was performed, with good immediate results and at one year of follow-up.

ABSTRACT Background: Cardiogenic shock (CS) is uncommon in the cardiac catheterization laboratory (CCL) among patients undergoing coronary angiography. Periprocedural CS is more frequent in high-risk patients and in technically demanding procedures. Aim: To describe the clinical outcomes of patients who underwent peripheral venoarterial extracorporeal membrane oxygenation (pVA-ECMO) for CS associated with interventional cardiology procedures. Material and Methods: Review of clinical records of seven patients treated between January 2014 and October 2018. Results: pVA-ECMO was implanted within 6 hours of the interventional cardiology procedure. All patients had coronary artery disease and one of them also had symptomatic severe aortic stenosis. One patient entered the CCL in cardiac arrest. Percutaneous coronary intervention (PCI) was performed in all patients; four patients underwent an emergency procedure and five patients experienced PCI complications. One patient undergoing transcatheter aortic valve replacement suffered acute severe aortic regurgitation. An intra-aortic balloon pump was inserted at the CCL in five patients. Six patients experienced cardiac arrest. Mean SAVE score was -4.3 and baseline lactate 55 mg/dl. pVA-ECMO mean duration was 5 ± 4 days. Survival after both hospital discharge and 12 months of follow-up was 85.7% Regarding vascular access complications, we observed one access site hematoma and one episode of cannulation site bleeding requiring surgical repair. Conclusions: pVA-ECMO should be considered in patients with periprocedural CS as a bridge to recovery. Its use was associated with improved clinical outcomes in this series.
Antecedentes: El shock cardiogénico (SC) es infrecuente en el laboratorio de cateterismo cardíaco (LCC) entre pacientes que son sometidos a coronariografía. El SC peri-procedimiento es más frecuente en pacientes de alto riesgo y en procedimientos técnicamente complejos. Objetivos: Describir los resultados clínicos de pacientes que fueron conectados a oxigenación con membrana extracorpórea veno-arterial periférica (ECMO-VAp) por SC peri-procedimiento de cardiología intervencional. Material y Métodos: Revisión de fichas clínicas de siete pacientes tratados en nuestro centro desde enero de 2014 a octubre de 2018. Resultados: ECMO-VAp fue utilizado dentro de las primeras 6 horas del procedimiento. Todos los pacientes tenían enfermedad coronaria y uno de ellos tenía además estenosis aórtica severa. Un paciente ingresó al LCC en paro cardíaco. Una intervención coronaria percutánea (ICP) fue realizada en todos los pacientes; 4 se realizaron procedimientos de emergencia y 5 pacientes tuvieron complicaciones de la ICP. A un paciente se le realizó un reemplazo valvular aórtico percutáneo y desarrolló una insuficiencia valvular aórtica aguda severa. Se instaló un balón de contrapulsación en el LCC en 5 pacientes. Seis pacientes tuvieron un paro cardiorrespiratorio. El valor del score de SAVE fue de -4,3 y el lactato basal 55 mg/dL. La duración media del ECMO-VAp fue 5 ± 4 días. La sobrevida al alta y a los 12 meses fue 85,7%. Como complicaciones del sitio de acceso vascular se observaron 1 hematoma y un episodio de sangrado que requirió reparación quirúrgica. Conclusiones: ECMO-VAp debería ser considerado en pacientes con SC peri-procedimiento como un puente a recuperación; su utilización estuvo asociada con mejoría de resultados clínicos en esta serie.

BACKGROUND: Increased Rho-kinase activity in circulating leucocytes is observed in heart failure with reduced ejection fraction (HFrEF). However, there is little information in HFrEF regarding other Rho-kinase pathway components an on the relationship between Rho-kinase and apoptosis. Here, Rho-kinase activation levels and phosphorylation of major downstream molecules and apoptosis levels were measured for the first time both in HFrEF patients and healthy individuals. METHODS: Cross-sectional study comparing HFrEF patients (n = 20) and healthy controls (n = 19). Rho-kinase activity in circulating leucocytes (peripheral blood mononuclear cells, PBMCs) was determined by myosin light chain phosphatase 1 (MYPT1) and ezrin-radixin-moesin (ERM) phosphorylation. Rho-kinase cascade proteins phosphorylation p38-MAPK, myosin light chain-2, JAK and JNK were also analysed along with apoptosis. RESULTS: MYPT1 and ERM phosphorylation were significantly elevated in HFrEF patients, (3.9- and 4.8-fold higher than in controls, respectively). JAK phosphorylation was significantly increased by 300% over controls. Phosphorylation of downstream molecules p38-MAPK and myosin light chain-2 was significantly higher by 360% and 490%, respectively, while JNK phosphorylation was reduced by 60%. Catecholamine and angiotensin II levels were significantly higher in HFrEF patients, while angiotensin-(1-9) levels were lower. Apoptosis in circulating leucocytes was significantly increased in HFrEF patients by 2.8-fold compared with controls and significantly correlated with Rho-kinase activation. CONCLUSION: Rho-kinase pathway is activated in PMBCs from HFrEF patients despite optimal treatment, and it is closely associated with neurohormonal activation and with apoptosis. ROCK cascade inhibition might induce clinical benefits in HFrEF patients, and its assessment in PMBCs could be useful to evaluate reverse remodelling and disease regression.

BACKGROUND: Pharmacological treatment improves survival in patients with heart failure with reduced ejection fraction. The use of sacubutril/valsartan and ivabradine has been recently approved and incorporated in the latest guidelines. AIM: To identify candidates eligible for these therapies among patients treated in a heart failure clinic, considering the inclusion criteria for the PARADIGM-HF and SHIFT trials. MATERIAL AND METHODS: Cross-sectional study on 158 patients aged 62 ± 11 years (67% male) with heart failure and reduced ejection fraction, with at least three months of follow-up and without decompensation. The percentage of patients complying for the inclusion criteria for the PARADIGM-HF y SHIFT trials was determined. RESULTS: In 37%, the etiology of heart failure was ischemic, 49% were in functional class I, their ejection fraction was 33 ± 11% and their median Pro-brain natriuretic peptide was 800 pg/mL. Ninety five percent were treated with vasodilators, 97% with beta-blockers and 82% with aldosterone antagonists. Using PARADIGM-HF and SHIFT criteria, 11 patients (7%) were eligible for sacubitril / valsartan and 21 patients (13.3%) for ivabradine. Among the main causes of non-eligibility for sacubitril / valsartan were being functional class I (48.7%) and not achieving a stable dose of enalapril ≥ 20 mg / day or losartan ≥ 100 mg / day (24.7%). In the case of ivabradine, apart from those in functional class I, the absence of sinus rhythm and a heart rate < 70 / min when receiving a maximal tolerated dose of beta-blockers, were present in 22%. CONCLUSIONS: A low percentage of our patients were eligible for these therapies. Among the causes that explain these results were clinical stability, a high percentage of patients in functional class I and being in a disease modifying treatment.

There has been a progressive increase in the use of mechanical circulatory support in our country in the last years, mainly in the short-term: as a bridge to cardiac transplant or recovery, which has allowed to rescue patients from a population that concentrates high rates of complications and mortality. This motivated that the Ministry of Health convened a series of experts in the area of heart failure, transplantation and mechanical circulatory support, representatives of different public and private health centers in Chile, with the objective of developing recommendations on the use of short-term mechanical assistance devices, which would serve as a reference for the proper management of these patients. This clinical experts consensus document contains topics related to: definitions and general concepts; indications; contraindications; specific aspects of starting, follow-up and weaning of the devices; process of transfer of patients in circulatory assistance from one center to another and finally criteria of organization, means and competences to be fulfilled by the centers that offer this therapeutic option.

Background: Galectin-3 (Gal-3) is a mediator of myocardial fibrosis involved in cardiac remodeling and a potential new prognosis marker in heart failure (HF). Aim: To measure Gal-3 at the moment of discharge in patients hospitalized for HF and its association with different variables. Material and Methods: Patients hospitalized for decompensated HF from four hospitals between August 2014 and March 2015, were included. Demographic, clinical and laboratory variables were recorded at the time of admission. At discharge, a blood sample was withdrawn to measure Gal-3 and brain natriuretic propeptide (Pro-BNP). Patients were separated in two groups, according to the level of Gal-3 (using a cutoff value of 17.8 ng/mL), comparing clinical and laboratory values between groups. Results: We included 52 patients with HF aged 70 ± 17 years (42% females). Functional capacity was III-IV in 46% of patients and the ejection fraction was 34.9 ± 13.4%. Pro-BNP values at discharge were 5,323 ± 8,665 pg/mL. Gal-3 values were 23.8 ± 16.6 ng/mL. Sixty percent of patients had values over 17.8 ng/mL. Those with elevated Gal-3 levels were older (75 ±16 and 62 ± 15 years, respectively, p = 0.025) and were hypertensive in a higher proportion (90.5% and 57.1% respectively, p = 0.021). Conclusions: In patients hospitalized for HF, Gal-3 levels are higher in older and hypertensive subjects.

BACKGROUND: Frailty is a geriatric syndrome characterized by a progressive impairment in the subjects ability to respond to environmental stress. Frailty is more commonly found in heart failure (HF) patients than in general population and it is an independent predictor of rehospitalization, emergency room visits and death. AIM: To estimate the prevalence of frailty in patients with decompensated HF admitted to four hospitals in Santiago, Chile. MATERIAL AND METHODS: Cross-sectional study. Subjects aged 60 or older consecutively admitted for decompensated HF to the study centers between August 2014 and March 2015 were included. Frailty was defined as the presence of three or more of the following criteria: unintended weight loss, muscular weakness, depression symptoms (exhaustion), reduced gait speed and low physical activity. Independent variables were tested for association using simple logistic regression. Variables associated with frailty (p < 0.05) were included in a multiple logistic regression model. RESULTS: Seventy-nine subjects were included. The prevalence of frailty was 50.6%. Frail patients were mostly female (52.6%) and older than non-frail subjects (73.7± 7.9 vs 68.2 ± 7.1; p < 0.003). Independent predictors of frailty were age (Odds raio (OR) 1.10; 95% confidence intervals (CI): 1.03-1.17), quality of life measured with the Minnesota Living with Heart Failure Questionnaire (OR 1.07; IC95%: 1.03-1.11), previous hospitalizations (OR 2.56; 95%CI: 1.02-6.43) and number of medications (OR 4.46; 95%CI: 1.11-17.32). CONCLUSIONS: The prevalence of frailty in patients admitted to the hospital for decompensated heart failure is high. Age, quality of life, hospitalizations and polypharmacy were factors associated with frailty in this group of participants.

Subjects aged 60 or older consecutively admitted for decompensated HF to the study centers between August 2014 and March 2015 were included. Frailty was defined as the presence of three or more of the following criteria: unintended weight loss, muscular weakness, depression symptoms (exhaustion), reduced gait speed and low physical activity. Independent variables were tested for association using simple logistic regression. Variables associated with frailty (p < 0.05) were included in a multiple logistic regression model. Results: Seventy-nine subjects were included. The prevalence of frailty was 50.6%. Frail patients were mostly female (52.6%) and older than non-frail subjects (73.7± 7.9 vs 68.2 ± 7.1; p < 0.003). Independent predictors of frailty were age (Odds raio (OR) 1.10; 95% confidence intervals (CI): 1.03-1.17), quality of life measured with the Minnesota Living with Heart Failure Questionnaire (OR 1.07; IC95%: 1.03-1.11), previous hospitalizations (OR 2.56; 95%CI: 1.02-6.43) and number of medications (OR 4.46; 95%CI: 1.11-17.32). Conclusions: The prevalence of frailty in patients admitted to the hospital for decompensated heart failure is high. Age, quality of life, hospitalizations and polypharmacy were factors associated with frailty in this group of participants.
