Current guideline recommendations for the use of beta-blockers after myocardial infarction without reduced ejection fraction are based on trials conducted before routine reperfusion, invasive care, ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...

Ejection fraction (EF) measures how well the heart pumps blood. A normal ejection fraction is between 55% to 70%. A low ejection fraction can be a sign of heart failure. Ejection fraction (EF) ...

Heart failure with preserved ejection fraction, which accounts for half of all heart failure cases, occurs when the lower left chamber of the heart (left ventricle) isn't able to fill properly with ...

Among patients with heart failure with preserved ejection fraction (HFpEF) who have chronotropic incompetence, those with lower left ventricular systolic volume might benefit from discontinuing beta ...
