Coronary heart disease primarily affects the cardiovascular system, specifically the coronary arteries. These arteries supply oxygen-rich blood and nutrients to the heart muscle. When these arteries become narrowed or blocked due to a buildup of plaque, it restricts blood flow to the heart, leading to coronary heart disease. The condition can result in chest pain (angina), heart attacks, and potentially life-threatening complications. A diagnosis can be made through a combination of medical history, physical examination, diagnostic tests such as electrocardiogram (ECG), stress tests, angiography, and blood tests to check for specific markers. Consulting with a healthcare professional, such as a cardiologist, is crucial for proper diagnosis, treatment, and management of coronary heart disease.
