It has been pumping blood since we were being formed in our mother's womb and has never stopped since then. As years go by our hearts go through various kinds of wear and tear - which gives way to heart attacks. This is indeed the greatest attack that is feared, faced and succumbed to by people in their old age. Now due to our mad lifestyles, the age at which this can occur is also undecided.

Cholesterol is a fatty chemical that is a part of the outer lining of cells in the body.
Smoking, high blood pressure, elevated cholesterol, and diabetes can accelerate plaque accumulation. Ultimately, atherosclerosis causes significant narrowing of the coronary arteries.

Typically, angina occurs with exertion, and subsides with rest. Unstable angina can be the indication of a heart attack in the near future.
