Detailed explanation-1: -Thickened heart muscle (hypertrophic cardiomyopathy). The most common cause of sudden cardiac death in young people is this genetic condition that causes the heart muscle to grow too thick. The thickening makes it hard for the heart to pump blood and can cause fast heartbeats.

Detailed explanation-2: -Sudden Arrhythmic Death Syndrome (SADS) This is a condition which means there was an unexplained underlying familial heart rhythm that was not detected until there was an investigation following a death.

Detailed explanation-3: -Coronary artery disease is the most common cause of sudden cardiac death, accounting for up to 80% of all cases. Cardiomyopathies and genetic channelopathies account for the remaining causes. The most common causes of non-ischemic sudden cardiac death are cardiomyopathy related to obesity, alcoholism, and fibrosis.

Detailed explanation-4: -Coronary artery disease causes most cases (80%) of sudden cardiac death. In people who are younger, congenital (since birth) heart defects or genetic abnormalities in their heart’s electrical system are often the cause. In people age 35 and older, the cause is more often related to coronary artery disease.
