ATHEROSCLEROSIS
Atherosclerosis is a condition where the arteries become narrowed and hardened due to a buildup of plaque, which is made up of fats, cholesterol, calcium, and other substances found in the blood. Over time, this plaque hardens, restricting blood flow to vital organs and tissues. It is a key contributor to cardiovascular diseases, including heart attacks, strokes, and peripheral artery disease.
Key Points about Atherosclerosis:
Plaque Formation: Plaques develop in the inner lining of arteries (endothelium). They begin as fatty streaks and can grow over time, becoming larger and more obstructive.
Causes: Common causes include high cholesterol, high blood pressure, smoking, diabetes, obesity, and a sedentary lifestyle.
Symptoms: Often, atherosclerosis does not show symptoms until an artery is significantly blocked. Depending on which arteries are affected, symptoms may include chest pain (angina), leg pain (claudication), shortness of breath, or even heart attacks and strokes.
Risk Factors:
- High levels of LDL cholesterol
- Hypertension (high blood pressure)
- Smoking
- Obesity
- Diabetes
- Poor diet and lack of physical activity
- Age and family history of heart disease
Complications:
- Coronary artery disease (if the heart arteries are affected), leading to angina or heart attacks.
- Carotid artery disease (if arteries to the brain are affected), leading to strokes.
- Peripheral artery disease (if leg arteries are affected), leading to pain or gangrene.
Diagnosis: Atherosclerosis can be diagnosed through imaging tests like angiograms, CT scans, and ultrasounds. Blood tests are also used to monitor cholesterol levels and other risk factors.
Treatment:
- Lifestyle changes: Diet (low in saturated fats and cholesterol), regular exercise, quitting smoking.
- Medications: Cholesterol-lowering drugs (statins), antihypertensive medications, and blood thinners.
- Surgical interventions: In severe cases, procedures like angioplasty (to widen arteries) or bypass surgery may be needed.
