Heart disease, a leading cause of death worldwide, manifests through a variety of symptoms. Recognizing these symptoms early can save lives by facilitating timely medical intervention.
Common Symptoms of Heart Disease
Chest Pain or Discomfort Chest pain, also referred to as angina, is one of the most recognizable symptoms of heart disease. This discomfort may feel like pressure, squeezing, or fullness and often occurs during physical activity or stress. Angina is caused by reduced blood flow to the heart (American Heart Association, 2025).
Shortness of Breath Shortness of breath, particularly during exertion or while lying flat, is another key indicator. It may signal that the heart is struggling to pump blood effectively, leading to fluid buildup in the lungs (Mayo Clinic, 2025).
Fatigue Persistent or unusual fatigue can occur when the heart cannot pump enough blood to meet the body's needs. This symptom is especially common in women and may precede other signs of heart disease (National Heart, Lung, and Blood Institute, 2025).
Swelling in the Legs, Ankles, or Feet Known as edema, swelling in the lower extremities may indicate heart failure. It results from the heart’s inability to efficiently circulate blood, causing fluid retention (Cleveland Clinic, 2025).
Irregular Heartbeat (Arrhythmia) Heart palpitations, skipped beats, or an irregular heartbeat may signal underlying heart conditions. Some arrhythmias are harmless, but others can be life-threatening (Johns Hopkins Medicine, 2025).
Less Common Symptoms
Heart disease can also present with less typical symptoms, including nausea, lightheadedness, or cold sweats. These are more frequently reported by women and may be mistaken for less severe conditions (American Heart Association, 2025).
