What are the risk markers for cardiovascular mortality?
The risk markers for cardiovascular mortality include ST-segment depression at a reduced workload or persisting into recovery coupled with exertional symptoms, low exercise capacity (generally defined as less than stage II of the Bruce protocol or #20% age- and sex-predicted values), failure to increase systolic BP to .120 mm Hg or a sustained .10 mm Hg decrease from resting values during exercise, complex ventricular ectopy or arrhythmias during stress or recovery, and delayed heart rate recovery (eg, ,10- or 12-beats-per-minute reduction in the first minute).
