Symptoms of Coronary Heart Disease
Symptoms of coronary heart disease vary depending on how far the disease has progressed. Some individuals may remain asymptomatic for years, while others may experience warning signs early on. In most cases, these symptoms become noticeable when the heart muscle is deprived of enough oxygen-rich blood, especially during physical activity or stress.
Common Symptoms
Chest pain or discomfort (angina): A hallmark symptom of coronary heart disease, angina often feels like pressure, tightness, or burning in the chest. It may radiate to the arms, neck, jaw, or back and is usually triggered by exertion or stress, resolving with rest.
Shortness of breath: Due to reduced blood flow, the heart cannot pump efficiently, leading to breathlessness during activity or while lying flat.
Fatigue: As the body compensates for reduced oxygen delivery, individuals may feel tired or weak, particularly after minor exertion.
Palpitations: Irregular heartbeats or a racing heart may indicate compromised heart function.
Dizziness or lightheadedness: Poor circulation may affect the brain, causing feelings of faintness.
Heart Attack Symptoms
In more advanced cases, a complete blockage can result in a heart attack (myocardial infarction), which may present with:
Intense, persistent chest pain
Sweating
Nausea or vomiting
Severe anxiety or a sense of impending doom
Pain radiating to the arm, neck, or jaw
Women may experience less typical symptoms such as abdominal pain, extreme fatigue, or back pain.
Silent Ischaemia | Symptoms of Coronary Heart Disease
Some people—especially those with diabetes—may experience silent coronary heart disease, where reduced blood flow occurs without any pain. These cases are often detected only through routine ECGs or stress tests.
In summary, symptoms of coronary heart disease may range from mild discomfort to severe, life-threatening events. Recognising early warning signs is crucial for timely diagnosis and treatment, potentially saving lives.
