“Prevention is the better then cure” we all have heard this as children and we even preach it to our children, but are we really respecting our bodies or abusing it. Does being regular at the gym and having a attractive body be the benchmark for good health… We have often read & heard that someone died after returning from workout, on the football field, while at work and majority of the times while asleep. These are some of the classic cases of death by what we term as Heart attack, which is the interruption of blood supply to part of the heart, causing heart cells to die. This is most commonly due to blockages in the coronary arteries.

Coronary artery disease (CAD) is the leading single cause of death in the world. Between 15% and 20% of all hospitalizations are the direct results of CAD.

Coronary artery disease (CAD), or more specifically, coronary atherosclerotic heart disease, is the primary cause of death in both men and women. Most CAD results from the deposition of atheromatous plaque in the large and medium-sized arteries of the heart. A less frequent and usually idiopathic form of CAD is due to coronary spasm. Coronary artery atherosclerosis starts insidiously and is usually distributed irregularly in various blood vessels. Atherosclerotic blood vessels have reduced expansion with systole and abnormal wave propagation. This can reduce or obstruct blood flow to areas of the myocardium, sometimes with seeming abruptness, resulting in myocardial ischemia.

The four most common and serious complications of CAD are angina pectoris, unstable angina, myocardial infarction, and sudden cardiac death as the result of arrhythmias.
