Prinzmetal ou spasme coronaire : une cause rare de mort subite

Prinzmetal's variant angina is a spastic angina, a rare case of aborted sudden death resulting from documented ventricular arrhythmias (ventricular tachycardy or ventricular fibrillation). A low prevalence of coronary artery spam in patients with aborted sudden death, normal coronary angiograms and unexplained ventricular fibrillation is described. Arrythmic cardiac arrest due to isolated coronary spasm is rare and there is limited information on the patients affected by this entity alone (case report). We report a case of a resuscitated sudden death, out-of-hospital cardiac arrest resulting from fatal ventricular arrythmias. Cardiac catheterisation revealed a coronary artery spasm. Association between cardiac arrest due to coronary-artery spam and the characteristics of life-threatening ventricular arrythmias are studied.
