The pumping action of the heart pushes blood into the arteries with enough pressure to keep it following forward. The amount of blood pumped out of the heart (cardiac output) and the tone of the arteries (peripheral resistance) determine the amount of tension pushing against the walls of the arteries Read More...
The benefits of exercise are enormous, and if you have high blood pressure, it just might save your life. Regular exercise strengthens the heart and helps normalize blood pressure. Because it increases insulin sensitivity and stabilizes blood-glucose levels, it is one of the most effective therapies for insulin resistance, which is often a precursor to hypertension Read More...
What matters in a patient after a heart attack is the amount of muscles that have been rendered dead or damaged during the episode. The damaged or dead areas or muscles will not contribute to the pumping of blood from the heart, reducing the capacity of pumping. This pumping power of the heart (left ventricle which is the most important chamber) is called ejection fraction Read More...
