Coronary artery stenosis
- Coronary Artery Stenosis
Coronary artery stenosis refers to the narrowing of the coronary arteries, which are the blood vessels that supply oxygen-rich blood to the heart muscle. This condition can lead to coronary artery disease (CAD) and is a major cause of myocardial infarction (heart attack).
Causes[edit | edit source]
Coronary artery stenosis is primarily caused by atherosclerosis, a condition characterized by the buildup of plaque (a combination of fat, cholesterol, and other substances) on the inner walls of the arteries. Other causes may include:
- Coronary artery spasm
- Congenital heart defects
- Inflammation of the arteries
Risk Factors[edit | edit source]
Several risk factors contribute to the development of coronary artery stenosis, including:
- High blood pressure
- High cholesterol
- Smoking
- Diabetes
- Obesity
- Sedentary lifestyle
- Family history of heart disease
Symptoms[edit | edit source]
Symptoms of coronary artery stenosis may not be noticeable until the condition is advanced. Common symptoms include:
- Angina (chest pain)
- Shortness of breath
- Fatigue
- Heart palpitations
Diagnosis[edit | edit source]
Diagnosis of coronary artery stenosis typically involves:
Treatment[edit | edit source]
Treatment options for coronary artery stenosis include lifestyle changes, medications, and surgical procedures. These may involve:
- Lifestyle modifications such as diet and exercise
- Medications like statins, beta-blockers, and antiplatelet drugs
- Angioplasty and stent placement
- Coronary artery bypass grafting (CABG)
Prevention[edit | edit source]
Preventive measures to reduce the risk of coronary artery stenosis include:
- Maintaining a healthy diet
- Regular physical activity
- Quitting smoking
- Managing stress
- Regular health screenings
