Pharmacologic therapy of angina pectoris
1Dept of Pharmacology and Therapeutics, Louisiana State University Medical Center, Shreveport 71130-3932, USA.
Summary
Angina pectoris treatment involves organic nitrates, beta-blockers, calcium channel blockers, aspirin, and heparin. These medications manage symptoms and improve exercise tolerance by reducing oxygen demand or restoring blood flow.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Angina pectoris is a condition characterized by chest pain due to reduced blood flow to the heart.
- Current treatments are symptomatic and focus on managing pain and improving exercise tolerance.
Purpose of the Study:
- To review the primary drugs used in the treatment of various forms of angina pectoris.
- To outline the mechanisms of action and efficacy of these medications.
Main Methods:
- Review of pharmacological agents for angina treatment.
- Analysis of drug efficacy in stable effort angina, variant angina, and unstable angina.
Main Results:
- Organic nitrates, beta-blockers, and calcium antagonists reduce oxygen demand in stable effort angina.
- Calcium channel blockers and organic nitrates are key for variant angina by relieving coronary vasospasm.
- Aspirin and heparin reduce myocardial infarction risk in unstable angina, with aspirin improving survival.
Conclusions:
- Treatment strategies vary based on angina type.
- Medications primarily manage symptoms and reduce cardiovascular event risk.
