A study has proven that half the people who have heart attacks do not even know about them. They are absolutely unaware about these cardiac anomalies going on within their bodies.

Nearly 50% of the heart attacks that take place are silent but deadly killers. They don’t even allow the patient to be aware of their presence. Just like those heart attacks that cause chest pain and many other symptoms, these too may be the type that kill instantly or after a short duration of time.

The research was published in the American Heart Association's journal Circulation.

Not every heart attack is accompanied with chest pain, an out-of-breath feeling or profuse sweating. This sort of heart attack is said to be a silent one. In it blood flow to the heart muscle is very sharply reduced.

Yet we know that a silent heart attack is just as bad as a real one with all the symptoms that go with it. Since patients don’t know they have had a silent heart attack they may not refer to their GP thereby increasing their chances of dying from this sneaky disease.

9498 middle-aged people were analyzed in the study. The issue that was gone into in-depth was the risk of atherosclerosis. It involves a hardening of the arteries.

Differences between blacks and whites were noted down and also between males and females. About 317 patients had silent heart attacks while 386 had full-blown heart attacks that were expressed in the form of symptoms.

The patients were tracked for about 20 years on average. Silent heart attacks were found to constitute 45% of all heart attacks. They were also likely to end in death by up to three times the average rate.

Death by all other reasons was also increased by more than 34%. While these silent heart attacks were more likely to occur in men, they caused more deaths if they occurred in women.

Blacks also tend to suffer more from silent heart attacks than whites. There were a few factors that figured in the mix that skewed the results. These included: use of tobacco, overall BMI, high blood sugar, hypertension and cholesterol levels.

Most of the signs of silent heart attacks seem to go over the heads of both the doctors and patients. These silent but deadly killers ought to be given all the attention in the world since they are as lethal as real and normal run-of-the-mill heart attacks.
