Iron deficiency is present in approximately 50 percent of patients with heart failure with reduced left ventricular ejection fraction (HFrEF; ejection fraction: a measure of how well the left ventricle of the heart pumps with each contraction) and is associated with reduced functional capacity, poorer quality of life, and increased mortality.

In patients with the implantable device, the heart got smaller, the left ventricular diastolic volume decreased significantly and the heart became stronger, with significant improvements in left ventricular ejection fraction. (sciencedaily.com)
Left ventricular ejection times and cardiac output both increased in - flight, while time between heartbeats, arterial pulse pressure, and the blood pumped from the heart decreased. (physiologyinfo.org)
