Coronary vasospasms can cause angina and heart attacks even without significant artery blockages. The hyperventilation test is recommended for diagnosing vasospastic angina pectoris.

Area of Science:

Cardiology
Vascular Medicine

Background:

Coronary vasospasms can manifest in diverse clinical presentations, including Prinzmetal angina and myocardial infarction, often without significant coronary artery stenosis.
Diagnosing vasospastic angina pectoris requires differentiating it from obstructive coronary artery disease.

Observation:

Three patients presented with varied symptoms: typical Prinzmetal angina, ST-elevation myocardial infarction with normal coronaries, and ischemic chest pain with significant LAD stenosis but no high-grade lesions.
Coronary vasospasms were identified as the primary cause of symptoms in all presented cases.

Findings:

All patients treated with calcium channel blockers became asymptomatic, confirming the efficacy of this treatment.
The hyperventilation test demonstrates diagnostic value comparable to provocative tests like ergonovine or acetylcholine for coronary vasospasms.

Implications:

Hyperventilation testing is a valuable, non-invasive tool for the initial evaluation of suspected vasospastic angina.
Early diagnosis and treatment with calcium channel blockers can effectively manage coronary vasospasm and improve patient outcomes.
