Heart attacks (also known as Myocardial Infarctions) will occur when a blood clot becomes stuck in a narrowed artery of the heart, blocking blood filled with oxygen from the rest of the heart. The heart will try to make up for its weakened state by pumping faster, thus putting more strain on it.

There are medications that help with these symptoms and are crucial in treating heart attacks. Beta-blockers reduce the heart's tendency to pump faster reducing the strain on the heart. Aspirin has been shown to prevent more blood clots from forming.

Lower Left Ventricular Ejection Fraction refers to the amount (fraction) of blood that is pumped out
(ejected) from the left ventrical (the heart's pumping chamber) during each heart beat. Higher fraction
numbers indicate good heart function. A lower fraction number may be treated with Ace Inhibitors (ACE-I).
