IMPORTANCE: Worsening chronic heart failure (HF) is a major public health problem. OBJECTIVE: To determine the optimal dose and tolerability of vericiguat, a soluble guanylate cyclase stimulator, in patients with worsening chronic HF and reduced left ventricular ejection fraction (LVEF). DESIGN, SETTING, AND PARTICIPANTS: Dose-finding phase 2 study that randomized 456 patients across...

IMPORTANCE: Steroidal mineralocorticoid receptor antagonists, when added to a renin-angiotensin system blocker, further reduce proteinuria in patients with chronic kidney disease but may be underused because of a high risk of adverse events. OBJECTIVE: To evaluate the safety and efficacy of different oral doses of the nonsteroidal mineralocorticoid receptor antagonist finerenone, given f...

IMPORTANCE: The value of measuring levels of glycated hemoglobin (HbA1c) for the prediction of first cardiovascular events is uncertain. OBJECTIVE: To determine whether adding information on HbA1c values to conventional cardiovascular risk factors is associated with improvement in prediction of cardiovascular disease (CVD) risk. DESIGN, SETTING, AND PARTICIPANTS: Analysis of individual-par...

IMPORTANCE: Approximately one-third of patients with peripheral artery disease experience intermittent claudication, with consequent loss of quality of life. OBJECTIVE: To determine the efficacy of ramipril for improving walking ability, patient-perceived walking performance, and quality of life in patients with claudication. DESIGN, SETTING, AND PATIENTS: Randomized, double-blind, placebo-co...

CONTEXT: Obstructive sleep apnea (OSA) is strongly related to obesity. Weight loss is recommended as part of the overall management plan for obese patients diagnosed with OSA. OBJECTIVE: To determine whether surgically induced weight loss is more effective than conventional weight loss therapy in the management of OSA. DESIGN, SETTING, AND PATIENTS: A randomized controlled trial of 60 obe...
