Question 1

What antiplatelet medications are used to prevent blood clots in coronary artery disease?

Accepted Answer

Antiplatelet agents like aspirin and clopidogrel inhibit platelet aggregation, preventing blood clots that could cause heart attacks or strokes. Dual antiplatelet therapy is frequently used after stent placement to reduce restenosis risk. These medications are essential for patients with coronary artery disease or those at high risk of cardiovascular events.

Question 2

How do statins stabilize atherosclerotic plaques in coronary artery disease?

Accepted Answer

Statins lower LDL cholesterol and alter atherosclerotic plaque composition, making plaques less lipid-rich and more fibrous. This transformation creates more stable plaques less likely to rupture and cause acute cardiovascular events. Medications like atorvastatin and simvastatin are commonly prescribed to improve patient outcomes.

Question 3

What is the role of beta-blockers in managing coronary artery disease?

Accepted Answer

Beta-blockers such as metoprolol and atenolol reduce heart rate, blood pressure, and myocardial oxygen demand, helping control angina and improve survival after heart attack. They block adrenaline effects on the heart and help prevent arrhythmias. These medications are key components of pharmacological management for coronary artery disease.

Question 4

How do nitrates and calcium channel blockers relieve angina symptoms?

Accepted Answer

Nitrates like nitroglycerin expand blood vessels and enhance blood flow to the heart, providing rapid angina relief. Calcium channel blockers such as amlodipine and diltiazem relax and widen blood vessels by inhibiting calcium flow into heart and vessel cells, reducing blood pressure and angina. Both medication classes improve coronary perfusion.

Question 5

What is percutaneous coronary intervention and when is it used?

Accepted Answer

Percutaneous coronary intervention, or angioplasty, uses a balloon to dilate blocked arteries. A stent is often placed to keep the artery open and reduce restenosis risk. This revascularization procedure is performed when pharmacological therapy alone is insufficient to restore adequate blood flow to the heart muscle.

Question 6

How does coronary artery bypass grafting restore blood flow in coronary artery disease?

Accepted Answer

Coronary artery bypass grafting is a surgical procedure using a blood vessel from another body part, usually the leg or chest, to bypass blocked coronary arteries. This revascularization technique increases blood flow to the heart muscle and is commonly used in patients with multiple blocked arteries requiring restoration of adequate perfusion.

Question 7

What monitoring and follow-up care is essential after coronary artery disease treatment?

Accepted Answer

Regular check-ups assess cardiovascular status, medication adherence, and lifestyle modifications. Periodic diagnostic tests including stress tests, echocardiograms, and lipid profiles monitor treatment effectiveness. Patient education on diet, exercise, and smoking cessation supports long-term outcomes and helps detect worsening symptoms early.
