Dilated cardiomyopathy - Symptoms & causes - Mayo Clinic

Ejection fraction: An important heart test - Mayo Clinic
2023年2月17日 · A left ventricle (LV) ejection fraction of about 50% to 70% is categorized as normal. A mildly reduced LV ejection fraction is usually between 41% and 49%. A reduced LV ejection fraction is usually 40% or less. Even if you have a normal ejection fraction, your overall heart function may not be healthy.
Myocardial ischemia - Symptoms & causes - Mayo Clinic
2021年5月5日 · Myocardial ischemia, also called cardiac ischemia, reduces the heart muscle's ability to pump blood. A sudden, severe blockage of one of the heart's artery can lead to a heart attack.
