Why the study?
What clinical, electrocardiographic, exercise, and angiographic variables are most predictive of survival in medically and surgically treated patients with coronary disease?
What clinical, electrocardiographic, exercise, and angiographic variables are most predictive of survival in medically and surgically treated patients with coronary disease?
Left ventricular ejection fraction and resting ventricular arrhythmias are critical independent predictors of survival in patients with coronary disease, with their relative importance varying by treatment strategy.
No takes yet. Share an insight, caveat, or question.
LVEF and resting arrhythmias may inform treatment-specific risk stratification in coronary disease; leaves open validation in contemporary cohorts.
Hammermeister et al. (1979) studied this question.
