 What is Coronary artery disease?

Coronary artery disease is known as ischemic heart disease (IHD). It contains some cluster of diseases like stable angina, unstable angina, myocardial infarction, and sudden cardiac death. The symptoms of Coronary artery diseases are chest pain or pain in the shoulder and neck. Sometimes there may be some symptoms of heartburn. 

This may cause due to exercise or emotional stress, hypertension, smoking, diabetes, obesity, high blood cholesterol, etc. the mechanism includes fall of blood flow and oxygen due to atherosclerosis. 

This can be prevented by having a healthy diet, regular exercise, and keeping regular weight. This can be diagnosed by ECG, Echocardiogram, nuclear scan, CT angiography. It can be treated by coronary artery bypass surgery (CABG), Coronary stent, and Angioplasty.

Coronary Artery Disease is caused by damage to the coronary arteries, which are majorly responsible for carrying oxygen and nutrient-rich blood to the heart. The buildup of cholesterol plaque tends to block the arteries, reducing blood flow to the heart, resulting in reduced function. 

In some cases, damage to the coronary arteries can also occur due to other reasons, and limit the amount of blood flowing to the heart. Partial blockage results in chest pain, shortness of breath, etc, and complete blockage leads to a heart attack. The initial symptoms of Coronary Heart Disease are not prominent, with a majority of cases only being diagnosed when the conditions progress quite a bit.
