Coronary Heart Disease
Coronary heart disease (CHD) is a condition where the coronary arteries, which supply oxygen-rich blood to the heart muscle, become narrowed or blocked due to the buildup of plaque, known as atherosclerosis. This reduction in blood flow can cause chest pain (angina), shortness of breath, and other symptoms. This can be caused by various factors including genetic predisposition, poor lifestyle habits, such as following a standard american diet, and underlying medical conditions.
Key features of coronary heart disease:
- Narrowing or blockage of the coronary arteries due to atherosclerosis.
- Reduced blood flow to the myocardium (heart muscle), potentially leading to ischemia and infarction.
- May present acutely as myocardial infarction or chronically as stable angina.
Severe blockages can lead to heart attacks, where part of the heart muscle is damaged or dies. CHD is a major cause of death and disability globally, often preventable through lifestyle changes and medical treatment.
