Prevalence of and association between silent myocardial ischemia and new coronary events in older men and women with and without cardiovascular disease.

Objectives: To investigate the prevalence of silent ischemia (SI) in older men and women detected by 24-hour ambulatory electrocardiograms (AECGs) and the association between SI and new coronary events.

Design: In a prospective study, the prevalence of SI detected by 24-hour AECGs and the incidence of new coronary events in 915 older men and 1,874 older women with coronary artery disease (CAD); with hypertension, valvular disease, or cardiomyopathy without CAD; and with no cardiovascular disease were investigated.

Setting: Large long-term healthcare facility.

Prevalence and association of ventricular tachycardia and complex ventricular arrhythmias with new coronary events in older men and women with and without cardiovascular disease.

Background: We report the prevalence of ventricular tachycardia (VT) and of complex ventricular arrhythmias (VA) and their association with new coronary events in older men and women.

Methods: The prevalence of VT and of complex VA detected by 24-hour ambulatory electrocardiograms and the incidence of new coronary events in older persons with coronary artery disease (CAD), with hypertension, valvular disease, or cardiomyopathy without CAD, and with no cardiovascular disease was investigated in 915 men (mean age 80 +/- 8 years) and in 1,874 women (mean age 81 +/- 8 years) in a long-term health care facility. Follow-up was 45 +/- 30 months in men and 47 +/- 30 months in women.
