What is a heart attack?
A heart attack (also known as a myocardial infarction) is the death of heart muscle from the sudden blockage of a coronary artery by a blood clot. Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. Blockage of a coronary artery deprives the heart muscle of blood and oxygen,causing injury to the heart muscle. Injury to the heart muscle causes chest pain
and chest pressure sensation. If blood flow is not restored to the heart muscle within 20 to 40 minutes, irreversible death of the heart muscle will begin to occur. Muscle continues to
die for six to eight hours at which time the heart attack usually is "complete." The dead heart muscle is eventually replaced by scar tissue.
Approximately one million Americans suffer a heart attack each year. Four hundred thousand of them die as a result of their heart attack.

I typically have high blood pressure which has at times gone up to 218. I take Hyzaar 100/25 daily to maintain my pressure at around 130/90. The first time I went for surgery my blood pressure hit the floor, I never was told how low it went but low enough to stop the surgery and I had to have a cauterization before they would consider surgery. This has happened several times and once the surgical nurse caught it before I went into surgery and they gave me an IV which brought it back up and I was able to continue on and have the surgery. So, now when I go for surgery and must fast from midnight I cannot take the Hyzaar, for that day only I take Cozaar which is the same except for the diuretic and I notate on my history that I should have an IV started prior to anesthesia. Since I have bladder cancer I have had multiple surgeries and this has helped surgical delays. Published: September 10 ::
