We have read with great interest the article published by Wang et al. on the clinical risk score to predict mortality in Chinese patients hospitalized for heart failure (HF). The authors developed a scale with five variables to predict mortality from HF after hospital discharge within one year: age, female sex, New York Heart Association (NYHA) score >3, left atrial diameter, and body mass index; with good predictive ability. One limitation of the study is the design of random division […]

Abstract Background: Most cardiovascular deaths occur in low- and middle-income countries and myocardial infarction is one of the main life-threatening conditions. Objective: We assessed all-cause in-hospital mortality in patients admitted for myocardial infarction (STEMI and NSTEMI) in Latin America and the Caribbean from 2000 onward. Methods: We systematically searched in electronic bibliographic databases for cohort studies which reported in-hospital mortality due to STEMI and NSTEMI. A meta-analysis was performed and a p-value < 0.05 was considered significant. Results: We identified [...]

Abstract Background: Transcatheter aortic valve replacement (TAVR) is a worldwide adopted procedure with rapidly evolving practices. Regional and temporal variations are expected to be found. Objective: To compare TAVR practice in Latin America with that around the world and to assess its changes in Latin America from 2015 to 2020. Methods: A survey was applied to global TAVR centers between March and September 2015, and again to Latin-American centers between July 2019 and January 2020. The survey consisted of questions […]
