Dear Dr. Roach: After reading several of your columns, where readers asked if they are too old for some activity, I wanted to make older adults aware of their untapped reservoir of energy and ability.

Whether revascularization by percutaneous coronary intervention (PCI) can improve event-free survival and left ventricular function in patients with severe ischemic left ventricular systolic ...

In patients with heart failure with preserved ejection fraction (HFpEF) and chronotropic incompetence, indexed left ventricular systolic volume (iLVESV) may predict those who could benefit most from ...

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 ...

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) ...

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, ...

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 ...
