Coronary artery disease (CAD), also referred to as coronary heart disease, is a condition characterized by the narrowing or blockage of the arteries that supply oxygen-rich blood to the heart muscle. This restriction is primarily caused by the build-up of plaque within the arteries, which impairs the heart’s ability to receive sufficient oxygen. Without adequate oxygen, the heart’s function is compromised, leading to potentially serious complications.
Causes and Risk Factors of Coronary Artery Disease
Several factors can increase the likelihood of developing CAD, such as high blood pressure, high cholesterol, diabetes, and smoking. Fortunately, by adopting healthier lifestyle habits, we can reduce our risk of CAD significantly.
Types of Coronary Artery Disease
Coronary artery disease is typically categorized as either chronic or acute. These two forms present differently:
-
Stable Ischemic Heart Disease:
This is a chronic condition in which the coronary arteries gradually narrow over time, limiting oxygenated blood flow to the heart. Patients may live with this for years without symptoms.
-
Acute Coronary Syndrome:
This is an emergency condition where a blood clot suddenly blocks blood flow to the heart, often resulting in a heart attack.
Common Symptoms of Coronary Artery Disease
Symptoms of CAD can vary, but the most common include:
- Angina (chest pain)
- Shortness of breath
- Heart palpitations
- A feeling of tightness or heaviness in the chest
- Pain in the arms, neck, or shoulder
- Fatigue, sweating, dizziness, or nausea
What Causes Coronary Artery Disease?
The primary cause of CAD is atherosclerosis, a condition where plaque, made up of cholesterol and fat, builds up in the arteries. Over time, this plaque hardens and narrows the arteries, restricting blood flow and potentially leading to chest pain (angina) or even a heart attack.
Diagnosing Coronary Artery Disease
Diagnosing CAD involves several methods, including physical exams, electrocardiograms (EKG), and stress tests. More advanced diagnostic tools may include cardiac catheterization, coronary angiograms, or coronary calcium scans.
Treatment Options for Coronary Artery Disease
Treatment for CAD depends on its severity and includes:
- Lifestyle Changes: Quitting smoking, maintaining a healthy diet, exercising, and limiting alcohol can significantly improve heart health.
- Medications: Drugs such as aspirin, beta-blockers, nitroglycerin, and statins are often prescribed to manage symptoms and reduce risks.
- Surgery: Procedures like coronary angioplasty and stenting help open blocked arteries, while coronary artery bypass grafting (CABG) creates new paths for blood flow around blocked arteries.
Risk Factors for Coronary Artery Disease
Certain risk factors increase the likelihood of developing CAD:
- Smoking: Smokers are at a much higher risk of CAD.
- High Blood Pressure, Cholesterol, and Family History: These are significant contributors to CAD risk.
- Age: Men over 45 and women over 55 face a greater risk.
- Obesity: Being overweight can lead to conditions like diabetes and hypertension, both of which raise the risk of CAD.
Managing Coronary Artery Disease
CAD management is essential, especially given its prevalence in India, where about 21% of diabetic patients are affected. Key strategies for managing CAD include:
- Quitting smoking
- Maintaining a healthy weight
- Monitoring blood pressure and cholesterol levels
- Eating a heart-healthy diet
- Exercising regularly
- Managing stress and limiting alcohol consumption
