WHAT IS THE CAUSE OF HEART ATTACK? Almost all heart attacks are sudden in onset and the cause is rupture of growing blockages. The blockages are usually covered by a thin membrane called intimal membrane, which also keeps the deposits intact.

This leads to the formation of a clot or thrombus inside the tube, closing the lumen completely. This compl...
