This book is devoted to heart attack and its prevention. We have established a forum called “Heart Attack Prevention Forum” for making general public aware about the ways of preventing and avoiding heart attacks. In the next one year we plan to bring out more literature, films and books on the subject. Heart attack or myocardial infarction (in medical terminology) is one of the unfortunate complications of heart diseases or coronary blockages. These blockages grow slowly over the years in people who have problems like high cholesterol, triglycerides, high blood pressure, diabetes, sedentary lifestyle and high-fat food. Stresses of modem day living also add up tremendously to increment of blockages. After 50% of the heart tubes (coronary arteries) are closed by these blockages, the membrane guarding the fatty deposits becomes vulnerable to sudden rupture. This rupture leads to a clot formation which closes the tube completely. This immediately leads to heart attack.
