[New-onset stenocardia: the detection of clinical variants of ventricular arrhythmia].
A total of 130 patients with angina of new onset (ANO), i.e. first three months after the onset of anginal attacks, were investigated by means of 24- and 48-hour Holter's electrocardiographic monitoring. All the patients underwent selective coronarography. Ventricular arrhythmias (isolated and paired extrasystoles, ventricular tachycardias) and their correlation to acute myocardial ischemia were analysed. Ventricular tachycardia was more common in unstable ANO, as compared to stable angina, and in patients with signs of coronary spasm, as compared to anginal patients showing no such signs. The combination of unstable angina with signs of coronary spasm is the least favorable ANO variant in terms of the risk of grave ventricular arrhythmias.
