Many of my family have suffered from heart attacks. I have even experienced one at age 39 years of age. My paternal grandmother that raised my brother and I after my fathers death, died from a heart attack on October 31, 1974. She had gotten up with us to get the kids ready for school, talked a little, went to the restroom, and there she died. That fast she was gone. You never know when this disease is going to strike. You never know to what severity it will be. Please read and be aware of some of the early warning signs below:



Heart Attack



What is a heart attack?
A heart attack occurs when the blood supply to part of the heart muscle itself -- the myocardium -- is severely reduced or stopped. The medical term for heart attack is myocardial infarction. The reduction or stoppage happens when one or more of the coronary arteries supplying blood to the heart muscle is blocked. This is usually caused by the buildup of plaque (deposits of fat-like substances), a process called atherosclerosis. The plaque can eventually burst, tear or rupture, creating a "snag" where a blood clot forms and blocks the artery. This leads to a heart attack. A heart attack is also sometimes called a coronary thrombosis or coronary occlusion.

If the blood supply is cut off for more than a few minutes, muscle cells suffer permanent injury and die. This can kill or disable someone, depending on how much heart muscle is damaged.

Sometimes a coronary artery temporarily contracts or goes into spasm. When this happens the artery narrows and blood flow to part of the heart muscle decreases or stops. We're not sure what causes a spasm. A spasm can occur in normal-appearing blood vessels as well as in vessels partly blocked by atherosclerosis. A severe spasm can cause a heart attack.
