by Dr. Anitha Reddy · June 25, 2026
Introduction
Heart disease remains one of the leading causes of death worldwide, yet many of its early signs are easy to overlook. Recognising these signals early can make the difference between timely treatment and a medical emergency.
Common Warning Signs
Chest discomfort, shortness of breath, unusual fatigue, an irregular heartbeat and swelling in the legs are among the most common indicators that your heart may need attention.
When to See a Doctor
If you experience persistent chest pain, breathlessness at rest, or fainting spells, seek medical care immediately. An ECG and echocardiography can detect problems before they become serious.
Prevention
A heart-healthy lifestyle — a balanced diet, regular exercise, no tobacco, and routine check-ups — dramatically lowers your risk of cardiovascular disease.
