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.

Hypertension is an important risk factor for adverse cardiovascular events, including stroke. Achieving blood pressure (BP) control, therefore, is an essential step to reduce the impact the condition has on patients' health. However, it is estimated that only 10% of patients with hypertension reach their BP goal. Resistant hypertension (RH) is a phenotype of hypertension characterized by high risk and difficulty in achieving BP goal. 1 It is defined as uncontrolled BP despite the use of 3 or more antihypertensive drugs in adequate doses, including a diuretic, a calcium channel blocker, and a reninangiotensin system blocker, or controlled BP with the use of 4 or more medications. 2,3 This classification allows the identification of patients who share clinical and epidemiological characteristics and who can benefit from specific strategies. 4,5 It is estimated that 11.7% to 13.7% of all patients with hypertension have RH. [6][7][8] Refractory hypertension (RfH) is a severe subtype of RH and is defined as uncontrolled BP despite the use of 5 or more antihypertensive drugs, including spironolactone and a thiazide-like diuretic. 2,3 The prevalence of RfH
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
