Question 1

What medications are used to manage angina symptoms?

Accepted Answer

Angina management uses multiple medication classes. Nitrates like nitroglycerin dilate coronary arteries and increase blood flow. Beta-blockers such as metoprolol reduce heart rate and oxygen demand. Calcium channel blockers including amlodipine decrease afterload and oxygen requirements. Antiplatelet agents like aspirin prevent clot formation, while anticoagulants such as heparin inhibit blood clot development in unstable angina cases.

Question 2

When is percutaneous coronary intervention recommended for angina?

Accepted Answer

Percutaneous coronary intervention becomes necessary when medications fail to relieve angina symptoms. This procedure involves inserting a balloon catheter into narrowed coronary arteries, inflating it to open the vessel, and placing a stent to maintain patency. The stent is a permanent wire mesh tube that restores blood flow to the heart when conservative therapy proves ineffective.

Question 3

How does coronary artery bypass grafting treat severe angina?

Accepted Answer

Coronary artery bypass grafting is a surgical procedure recommended for patients with severe coronary artery disease or those unresponsive to other treatments. A blood vessel from the chest, leg, or arm is harvested and attached to the coronary artery, bypassing the narrowed area or blockage. This restores adequate blood flow to the myocardium and relieves angina symptoms.

Question 4

What role does supplemental oxygen play in angina management?

Accepted Answer

Supplemental oxygen is administered during angina management to increase oxygen supply to the myocardium, particularly in cases of hypoxemia. This medical intervention helps reduce the myocardial oxygen demand-supply mismatch and alleviates angina symptoms when patients experience low blood oxygen levels during acute episodes.

Question 5

Which lifestyle modifications are essential for angina management?

Accepted Answer

Critical lifestyle changes include adopting a heart-healthy diet with reduced saturated fats, engaging in 150 minutes of weekly moderate-intensity aerobic exercise, quitting smoking, limiting alcohol intake, and practicing stress-reducing techniques like deep breathing. These modifications prevent atherosclerosis progression, reduce myocardial infarction risk, and support overall cardiovascular health in angina patients.

Question 6

Why is smoking cessation particularly important for angina patients?

Accepted Answer

Smoking cessation is one of the most critical lifestyle changes because smoking accelerates atherosclerosis progression and significantly increases myocardial infarction risk. Eliminating tobacco use reduces cardiovascular strain, improves oxygen delivery to the heart, and prevents further coronary artery narrowing in patients with angina.

Question 7

How do angiotensin receptor blockers benefit angina management?

Accepted Answer

Angiotensin receptor blockers such as losartan and valsartan are used in patients intolerant to ACE inhibitors. These medications block angiotensin II effects, promoting vasodilation and reducing blood pressure. They provide similar cardiovascular benefits to ACE inhibitors while offering an alternative for patients with specific medication sensitivities or contraindications.
