top most cardiac doctors in bangalore Cholesterol complications typically arise when there are imbalances in cholesterol levels in the blood, particularly with high levels of LDL (low-density lipoprotein) or low levels of HDL (high-density lipoprotein). Here's a breakdown of the potential complications: 1. Atherosclerosis Cause: Excess LDL cholesterol can lead to the buildup of fatty deposits (plaques) in the walls of arteries. Complication: Over time, these plaques harden and narrow the arteries, restricting blood flow and leading to a condition known as atherosclerosis. 2. Coronary Artery Disease (CAD) Cause: Cholesterol deposits in the coronary arteries (those that supply the heart) can reduce or block blood flow. Complication: This may result in chest pain (angina), heart attacks, or other heart conditions due to reduced oxygen to the heart. 3. Heart Attack (Myocardial Infarction) Cause: When cholesterol plaques rupture, they can form a blood clot, blocking the artery completely. Complication: This can cut off blood flow to a part of the heart muscle, resulting in permanent damage or a heart attack.
