Coronary vasospasm in a patient with respiratory failure: A case report and a brief review.

摘要

Coronary vasospasm is an episodic, augmented, contractile response of coronary smooth muscles to variety of stimuli in the setting of established endothelial dysfunction. Various physiological including cold, stress and pathological factors like smoking, and ethanol have been well known to precipitate vasospasm. Despite these omnipresent factors, coronary vasospasm has become infrequent, in particular due to judicious use of medication including calcium channel blockers, statins and aspirin. We present a case of severe coronary vasospasm resulting in haemodynamic instability, in a patient with hypoxic respiratory failure. Recurrent symptomatic episodes required coronary angiography for the diagnosis and patient was successfully treated with calcium channel blockers.
