Plaque Rupture: A Major Cause of Heart Attacks
While heart attacks are usually caused by the narrowing or complete blockage of the coronary artery due to plaque buildup, plaque can also break loose, causing a clot blockage large enough to trigger a heart attack.
Different plaques have different composition, and not all plaques are prone to rupture. Fibrotic, or calcified, plaques, are more stable and less prone to rupture. Lipid Core Plaques (LCP), on the other hand, have thin fibrous caps, making them vulnerable to rupture.
