Effect of age on postmyocardial infarction ventricular arrhythmias (Holter Registry data from CAST I and CAST II). Cardiovascular Arrhythmia Suppression Trials

Holter data from the 17,609 postmyocardial infarction patients in the CAST Registry were analyzed to study the effect of age on VPC and VT incidence and frequency. Multivariable analysis demonstrated that age is an important independent predictor of increased ventricular ectopy, with the median rate...

Beschreibung
Zusammenfassung:	Holter data from the 17,609 postmyocardial infarction patients in the CAST Registry were analyzed to study the effect of age on VPC and VT incidence and frequency. Multivariable analysis demonstrated that age is an important independent predictor of increased ventricular ectopy, with the median rate of VPCs/hour increasing from 0.4 (patients aged < 50 years) to 4.0 (patients aged 75 to 80 years), and the prevalence of VT increasing from 7.3% (patients aged < 50 years) to 15.3% (patients aged 75 to 80 years).
