Study Notes
Angina Pectoris: Overview
- Angina pectoris is sudden chest pain, often radiating to the shoulder, arm, and jaw.
- It's a symptom of insufficient oxygen supply to the heart, often due to coronary artery disease (CAD).
- Over 10 million Americans have chronic stable angina, with ~500,000 new cases annually.
- Angina treatment aims to prevent myocardial infarction (MI) and death, and relieve myocardial ischemia and pain.
Types of Angina
- Chronic stable angina (exertional angina): Pain triggered by exertion, emotional stress, or large meals. The underlying cause is CAD, where plaque buildup restricts blood flow.
- Variant angina (Prinzmetal or vasospastic angina): Pain occurs at any time, even during rest or sleep. Caused by coronary artery spasm.
Treatment Strategies for Stable Angina
- Goal: Reduce anginal attack frequency and intensity.
- Mechanism: Primarily decrease oxygen demand by affecting heart rate, contractility, afterload, and preload.
- Drugs: Organic nitrates, beta blockers, calcium channel blockers (CCBs), and ranolazine.
- Nondrug therapy: Avoid angina triggers, manage risk factors (smoking, hypertension, hyperlipidemia, sedentary lifestyle) through interventions like exercise and lifestyle changes.
Treatment Strategies for Variant Angina
- Goal: Reduce attacks by increasing oxygen supply.
- Mechanism: Use vasodilators to prevent or relieve coronary artery spasm.
- Drugs: CCBs and organic nitrates.
Organic Nitrates (e.g., Nitroglycerin)
- Mechanism: Cause vasodilation, primarily affecting veins to decrease venous return and preload, lowering oxygen demand.
- Action in Stable Angina: Decreases venous return and ventricular filling, lowering preload.
- Action in Variant Angina: Relaxes/prevents coronary artery spasm, raising oxygen supply.
- Pharmacokinetics: Rapid hepatic metabolism, short half-life (5-7 minutes). Requires frequent redosing.
- Adverse effects: Headache, hypotension, reflex tachycardia.
- Tolerance: Rapid development with continuous use. Prevention involves intermittent use, allowing for at least 8 drug-free hours daily.
- Uses: Acute angina attack treatment and short-term prophylaxis.
Beta Blockers
- Mechanism: Decrease cardiac oxygen demand by blocking β1 receptors, slowing heart rate and reducing contractility. Also lower afterload a bit.
- Advantage: Decrease risk of death.
- Use: First-line treatment for chronic stable angina.
- Adverse Effects: Bradycardia (slow heartbeat), decreased atrioventricular (AV) conduction, contractility reduction, bronchoconstriction (use cautiously with asthma patients). Masking of hypoglycemia symptoms in diabetics.
Calcium Channel Blockers (CCBs)
- Mechanism: Dilate peripheral arterioles (reducing afterload) and sometimes coronary arteries too. Verapamil and diltiazem also slow heart rate.
- Use: Treat both stable and variant angina.
- Adverse Effects: Lower blood pressure, may stimulate reflex tachycardia. Be cautious in patients with bradycardia, heart failure, or AV block.
Ranolazine
- Mechanism: Does not lower heart rate or vascular resistance; possibly increases myocardial energy efficiency.
- Use: Can supplement other antianginal drugs.
- Adverse effects: QT prolongation, drug interactions (especially CYP3A4 inhibitors).
Risk Factor Reduction
- Key modifiable risks: Smoking cessation, aerobic exercise, hypertension treatment (130/80 mmHg or less), cholesterol management, blood glucose control in diabetics.
Drug Selection and Management
- Initial treatment often involves sublingual nitroglycerin plus a long-acting agent (beta blocker preferred for mortality reduction).
- Sequential addition of drugs (beta blockers, CCBs, or nitrates) based on response
- Consider revascularization (PCI, CABG) if medical therapy insufficient.
- Specific treatment adjustments exist for those with comorbid conditions.
Drug Interactions
- Nitrates can intensify the effects of other blood pressure-lowering agents.
- Certain drugs inhibit CYP3A4 and can increase ranolazine levels.
- Some drugs prolong the QT interval, and patients taking ranolazine should avoid these to prevent Torsades de pointes.
