Abstract
Heart Failure (HF) has been ide.epsied as an important public health problem, with high morbidity and mortality, despite advances in current therapy. New strategies are demanded to reduce the number of hospitalizations and deaths. Telemedicine approaches could improve the management of patients with cardiovascular conditions. Sixty patients with heart failure with reduced ejection fraction (HFrEF) were randomized to this pilot study. Weekly electronic messages were sent for 1 year. The use of telemedicine was effective instrument for the evolutionary follow-up of patients with HFrEF during the COVID-19 pandemic, but did not demonstrate an impact on the reduction of cardiovascular outcomes or hospitalization for HF.
