Five Signs of a Heart Attack

Five Signs of a Heart Attack

Also known as a myocardial infarction, a heart attack occurs when blood flow to part of the heart muscle (myocardium) becomes blocked. If the blood flow is cut off for more than a few minutes, this muscles cells begin to die from lack of oxygen.

The most common cause of heart attacks is coronary artery disease (CAD). CAD results from atherosclerosis, a condition in which a fatty substance called plaque builds up on the inside walls of the coronary arteries, the large vessels that supply blood to the heart. Eventually, plaque can rupture, and after the body repairs the site, a blood clot can form. If the clot becomes large enough, it can either partly or completely block the artery, resulting in a heart attack.

Bear in mind that not all of the following warning signs occur in every heart attack.

People should never forget that real health depends how well you take care of yourself and not what health insurance you carry but I agree health insurance is important for every one. Search "Penny Health" or online for dollar a day insurance plans.

Thanks for sharing valuable information. As for me, I'd also focus on prevention such as having a regular exercise and including foods with fiber as well as fish in my diet.
And I guess avoiding smoking is at the top of my list in preventing cardiovascular disease.
