Here is a comparison table of different types of angina tailored for a clinical pharmacist, summarizing key features including causes, symptoms, and treatment options:
| Type of Angina | Causes/Triggers | Symptoms | Treatment Considerations |
|---|---|---|---|
| Stable Angina | – Atherosclerosis causing fixed coronary artery narrowing | – Predictable chest pain with exertion or stress | – Rest and short-acting nitrates (e.g., sublingual nitroglycerin) for immediate relief |
| – Triggers: physical activity, emotional stress, cold/hot exposure, heavy meals | – Pain lasts ≤5 minutes, relieved by rest or nitrates | – Beta blockers or calcium channel blockers preferred for chronic management | |
| – Pain may radiate to jaw, neck, arms, back | – Aspirin and statins for secondary prevention | ||
| Unstable Angina | – Ruptured atherosclerotic plaque, thrombosis leading to sudden blood flow reduction | – Unexpected severe chest pain at rest or minimal exertion | – Medical emergency requiring immediate evaluation and treatment |
| – May worsen over time | – Pain lasts >20 minutes, not relieved by rest or nitrates | – Antiplatelet agents, anticoagulants, possible revascularization procedures (PCI or CABG) | |
| – Possible progression to myocardial infarction | |||
| Variant (Prinzmetal) Angina | – Coronary artery spasm possibly triggered by stress, smoking, cocaine, cold weather | – Severe chest pain often at rest, mainly night/early morning | – Calcium channel blockers and long-acting nitrates |
| – Occurs often in younger patients, often near fixed coronary artery lesions | – Pain relieved by vasodilators | – Avoid triggers such as smoking, cocaine | |
| Microvascular Angina | – Dysfunction of small coronary vessels (coronary microvascular disease) | – Severe, prolonged chest pain, sometimes >30 minutes | – May not respond well to nitrates |
| – More common in women, especially peri- or postmenopausal | – Pain may happen at rest or activity, associated with fatigue, shortness of breath | – Management includes medications that improve microvascular function and lifestyle changes | |
| – Beta blockers, calcium channel blockers, ACE inhibitors can be used |
This table incorporates clinical features, typical patient presentation, and treatment strategies relevant for clinical pharmacists involved in management and medication counseling. It highlights differences in pathophysiology, symptom patterns, and urgency of treatment among the types of angina.
