Coronary artery disease occurs due to damage to the main blood vessels that supply oxygen and various nutrients through blood to the heart. These blood vessels are called coronary arteries. Deposition of cholesterol and formation of plaque (atherosclerosis) is the main reason that causes damage to these arteries.
When the plaque builds up and hardens, it blocks the coronary arteries, which in turn reduces the flow of blood to the heart. Over the time, this plaque keeps building and when the blood flow is reduced drastically the main symptoms of coronary artery disease like chest pain (angina) and breathlessness are seen. Complete blockage of the artery leads to a heart attack. Because the process of deposition of cholesterol is gradual, progression of coronary artery disease goes unnoticed.
Therefore, the best way to prevent coronary artery disease is to follow a healthy lifestyle and regular screening test for cholesterol levels and other parameters indicating the disease. In this section, you’ll find several articles suggesting diet and lifestyle changes for a healthy heart. You can read specific information on silent heart attacks, consequences of cholesterol and awareness on chronic heart disease.
