Blocked heart arteries are a condition where the coronary arteries narrow or become fully blocked because of the build-up of fatty deposits, cholesterol, calcium, and other compounds called plaque. This illness, coronary artery disease, inhibits the flow of oxygen-rich blood to the heart muscle. Initially, modest blockages can go unnoticed. But if the narrowing develops, patients may report chest pain (angina), shortness of breath, exhaustion, dizziness, or discomfort with physical exercise or mental stress. If the plaque ruptures and a blood clot suddenly blocks the artery completely, a life-threatening heart attack can occur.

What are the risk factors for heart disease?

High blood pressure, diabetes, high cholesterol, smoking, obesity, physical inactivity, chronic stress, unhealthy eating habits Family history of heart disease. Diagnosis is typically made by electrocardiography (ECG), stress testing, echocardiography, CT coronary angiography, or coronary angiography to evaluate the severity of the blockage.

Treatment varies on the degree of arterial narrowing and may involve lifestyle changes, cholesterol-lowering drugs, blood thinners, angioplasty with stent implantation, or coronary artery bypass graft ( CABG ) surgery. Early detection, routine health checks, and adopting a heart-healthy lifestyle are critical for preventing problems and enhancing long-term cardiovascular health.
