Approximately 20% had atrial fibrillation. Echocardiography showed that most patients had no LV regional wall motion abnormalities, with good global systolic function but evidence of LV hypertrophy.

For patients who have heart failure with reduced ejection fraction (HFrEF) and coronary artery disease, improvements in LV function after revascularization are linked to better long-term outcomes, an ...
