Coronary artery disease is one of the leading causes of heart attacks and deaths around the world. It develops when fatty deposits, known as plaques, slowly build up inside the arteries that supply oxygen-rich blood to the heart.
As these arteries become narrower, the heart receives less oxygen, making it harder to work properly.
This process often develops over many years without causing obvious symptoms. Many people do not know they have blocked arteries until they experience a heart attack or another serious heart problem. Learning to recognize the early warning signs can help people seek treatment before permanent damage occurs.
One of the best-known symptoms is chest pain, also called angina. People often describe it as pressure, tightness, heaviness, or squeezing in the chest rather than a sharp pain. The discomfort may spread to the shoulders, arms, neck, jaw, or back and often appears during exercise, emotional stress, or heavy physical activity before improving with rest.
Shortness of breath is another common warning sign. When the heart cannot pump enough oxygen-rich blood around the body, everyday activities such as walking, climbing stairs, or carrying groceries may suddenly become difficult. Some people even feel breathless while sitting or lying down.
Extreme tiredness can also signal that the heart is struggling. This symptom is especially common in women, who may notice they become unusually exhausted after doing routine tasks they previously managed with ease. The tiredness often appears without any clear explanation.
Not everyone experiences the classic symptoms. Some people, particularly those with diabetes, may have a silent heart attack with little or no chest pain because nerve damage reduces their ability to feel pain. Instead, they may notice mild discomfort, sweating, nausea, dizziness, or unexplained weakness.
Heart palpitations, which feel like a racing, pounding, or irregular heartbeat, can also occur when the heart is under stress. Although these symptoms do not always mean blocked arteries are present, they should not be ignored, particularly if they occur together with chest discomfort or breathlessness.
Research published in the American Journal of Cardiology has shown that people who recognize warning signs early and receive prompt medical treatment have a better chance of avoiding severe heart damage. The faster blood flow is restored, the more heart muscle can be saved.
Although some risk factors such as age and family history cannot be changed, many others can. High blood pressure, high cholesterol, diabetes, smoking, obesity, unhealthy eating habits, and physical inactivity all increase the risk of coronary artery disease. Managing these conditions and living a heart-healthy lifestyle can greatly reduce the chances of blocked arteries.
If you develop chest pain, unexplained shortness of breath, unusual fatigue, dizziness, nausea, or a fast or irregular heartbeat, do not ignore the symptoms. Seek medical attention as soon as possible, especially if the symptoms are severe or persistent. Early diagnosis and treatment can prevent a heart attack, protect the heart from lasting damage, and save lives.
