Types of angina

Variant (Prinzmetal) Angina: The Spasm

• Caused by temporary spasm of a coronary artery, not fixed blockage
• Typically occurs at rest, often at night or early morning, sometimes in cycles
• Can affect younger people and those without classic risk factors; smoking is a strong associate
• Treated with specific vessel-relaxing medicines (calcium-channel blockers, nitrates) - and smoking cessation is non-negotiable

Microvascular Angina: The Small-Vessel Problem

• Angina symptoms from dysfunction of the heart's tiniest arteries, with the big arteries looking normal on angiography
• More common in women; episodes can be longer and less GTN-responsive
• Diagnosed and managed by cardiologists - real disease, despite the "normal" angiogram that can wrongly reassure

The Classical Typing

Madhava Nidana and Charaka typed Hridroga five ways - Vataja (paroxysmal gripping pain, the closest to angina's portrait), Pittaja (burning), Kaphaja (heaviness, dull ache), Sannipataja (mixed, grave), and Krimija (from parasites, of its era). The classification is observational, not angiographic - interesting as early clinical phenomenology, with the Vataja type's episodic, fright-laden pain mapping most closely onto angina.

Frequently Asked Questions

Which type of angina is dangerous? Unstable angina is the immediate danger - it is treated like a heart attack. Stable angina is serious in a different way: it marks coronary disease that needs long-term management.

Can stable angina turn unstable? Yes - that transition is exactly what the "call emergency" rule watches for: rest pain, worsening pattern, or GTN no longer relieving.

Is variant angina curable? It is very manageable - the right medicines control spasm in most people, and quitting smoking transforms the outlook.

My angiogram was normal but I still get pain - was it wrong? Possibly microvascular angina or spasm - real conditions the angiogram does not show. Return to your cardiologist; "normal angiogram" is not the end of the question.
