Silent heart signals: 8 early warnings you mustn't ignore

Doctors say heart disease often begins with subtle signs long before chest pain. New or unusual fatigue, shortness of breath with everyday activities, pain or discomfort in the jaw/neck/back/arms, indigestion-like sensations, dizziness, unexplained sweating, swollen ankles, or an irregular heartbeat can all signal cardiac stress. Recognizing these early clues enables prompt evaluation and treatment to prevent progression, with emphasis on regular check-ups and managing blood pressure, diabetes, and cholesterol, alongside a healthy lifestyle.
