Additionally, individuals with a family history of heart disease or those who experience chronic stress are at an elevated risk.

It can silently harm the heart and is frequently confused with mild conditions like dyspepsia, exhaustion, or muscular soreness. Dr. Ravinder Singh Rao highlights that obesity, smoking, high blood pressure, diabetes, and high cholesterol are risk factors for a silent heart attack.
