Knowledge of coronary stents, thrombosis and dual antiplatelet therapy among Spanish dentists.

Introduction And Objectives: The coexistence of heart and dental disease is common and antiplatelet therapy with aspirin and clopidogrel following a percutaneous intervention can interfere with dental practice. Our aim was to study dentists' knowledge of percutaneous coronary interventions and their approach to affected patients.

Methods: A questionnaire was used to evaluate the knowledge of 100 randomly selected dentists in Spain about coronary stents, antiplatelet therapy, and guidelines prepared by American medical societies, including the American Dental Association, and to determine how frequently they consulted a cardiologist.

[Coronary spasm and heart arrest caused by ventricular fibrillation].

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.
