[Coronary spasm during coronary arteriography. Classification and interpretative criteria]

Area of Science:

• Cardiology
• Diagnostic Imaging

Context:

• Selective coronary angiography is crucial for diagnosing coronary artery disease.
• Coronary spasm can mimic or be associated with significant cardiac events.
• Distinguishing true coronary spasm from artifact is clinically important.

Purpose:

• To elucidate the multifaceted nature of coronary spasm observed during selective coronary angiography.
• To differentiate true pathological coronary spasm from catheter-induced spasm and apparent radiologic artifacts.
• To establish clinical criteria that, combined with angiographic findings, aid in interpreting the pathophysiology of coronary artery spasm.

Summary:

• Coronary spasm during angiography presents diverse etiologies, including catheter-induced spasms, functional angina, and myocardial infarction.
• Angiographic features of coronary spasm remain consistent regardless of clinical significance or underlying mechanism.
• This paper emphasizes the integration of clinical assessment with angiographic data to accurately interpret coronary artery spasm.

Impact:

• Improved diagnostic accuracy for coronary artery spasm.
• Enhanced understanding of the pathophysiology linking coronary spasm to angina and myocardial infarction.
• Better patient stratification and management strategies for suspected coronary artery spasm.
