EF% is a key indicator of the heart's pumping efficiency, representing the percentage of blood pumped out of the left ventricle with each heartbeat. A normal EF% should be greater than 50%, meaning at least half of the blood is effectively pumped throughout the body with each beat. An EF% of 40% or lower may indicate impaired heart function, particularly systolic heart failure.
The coronary arteries supply blood to the heart muscle, and their health directly impacts heart function and longevity. Coronary angiography is a method to assess the degree of coronary artery stenosis, with a stenosis of more than 50% increasing the risk of acute myocardial infarction.
Blood pressure reflects the pressure of blood against the walls of the blood vessels, indicating the heart's pumping condition. An ideal blood pressure level is around 120/80 mmHg. Both high and low blood pressure can strain the heart and blood vessels.
Heart rate refers to the number of heartbeats per minute. For adults, a normal heart rate typically ranges from 60 to 80 beats per minute. A heart rate that is too fast or too slow may signal heart problems and should be further evaluated.
By monitoring these indicators, we can better understand heart health and take action to maintain or improve it if necessary.
