We report the cases of three young men, heavy smokers, without previous heart disease and who were resuscitated after cardiac arrest due to ventricular fibrillation attributed to coronary spasm. All of them complained of atypical chest pain and the exercise testing, echocardiogram and coronary angiography were normal. The first case was diagnosed by Holter monitoring and by provocative testing with intracoronary ergonovine; the second by provocative testing with intracoronary acetylcholine and the third by Holter monitoring. The patients were treated with a calcium antagonist and/or nitrates and in the follow up they remained asymptomatic.

Early onset of cardiopulmonary resuscitation (CPR) and defibrillation are the most important factors for improving outcome after cardiac arrest. Many patients do not receive thrombolytic therapy after prolonged CPR, as there is a fear of serious bleeding complications. Ten patients with cardiac arrest and acute myocardial infarction were treated with primary angioplasty after prolonged CPR. Angioplasty was successful in nine of the patients, and left ventricular function was well preserved after six weeks. Primary angioplasty is highly effective and safe in establishing reperfusion in selected patients with acute myocardial infarction and cardiac arrest.
