- Understanding Coronary Artery Disease: Causes, Symptoms, and Treatment Options
Introduction
Coronary artery disease (CAD) is the most common type of heart disease and a leading cause of death worldwide. Despite its prevalence, CAD is often misunderstood or overlooked until serious complications arise. This blog provides an in-depth overview of CAD, shedding light on its causes, symptoms, and treatment options to help patients and families take informed actions for better heart health.
What is Coronary Artery Disease?
Coronary artery disease occurs when the coronary arteries, which supply oxygen-rich blood to the heart, become narrow or blocked. This happens due to atherosclerosis—a buildup of fatty deposits (plaque) on the artery walls. Over time, this reduces blood flow to the heart muscle, leading to symptoms like chest pain or, in severe cases, a heart attack.
Causes and Risk Factors
Several factors contribute to the development of CAD:
- High Cholesterol: Excess cholesterol forms plaques in the arteries.
- Smoking: Damages the lining of arteries, leading to plaque buildup.
- Sedentary Lifestyle: Increases the risk of obesity, diabetes, and hypertension.
- Genetic Predisposition: A family history of heart disease raises the risk.
- Diabetes and Hypertension: Accelerates arterial damage.
Symptoms to Watch For
CAD symptoms may vary depending on the severity of blockage:
- Chest Pain (Angina): Discomfort or tightness often triggered by physical activity or stress.
- Shortness of Breath: Resulting from reduced oxygen supply to the heart.
- Fatigue: The heart struggles to pump efficiently, leaving you feeling tired.
- Heart Attack Symptoms: Severe chest pain, cold sweats, nausea, and lightheadedness.
Treatment Options
The treatment of CAD is focused on improving blood flow to the heart, relieving symptoms, and preventing complications.
- Lifestyle Changes:
- Adopting a low-fat, heart-healthy diet rich in fruits, vegetables, and whole grains.
- Regular exercise to strengthen the heart muscle and improve circulation.
- Stress management techniques like yoga and meditation.
- Medications:
- Cholesterol-lowering drugs (statins).
- Blood pressure medications.
- Antiplatelet drugs like aspirin to prevent clot formation.
- Surgical Interventions:
- Angioplasty and Stenting: Opens blocked arteries using a balloon and stent.
- Coronary Artery Bypass Grafting (CABG): Redirects blood flow around blocked arteries.
