Why the study?
Does coronary bypass surgery improve left ventricular function as measured by non-invasive systolic time intervals in patients with ischaemic heart disease?
Does coronary bypass surgery improve left ventricular function as measured by non-invasive systolic time intervals in patients with ischaemic heart disease?
Coronary bypass surgery appears to preserve rather than improve overall left ventricular function at 6 months, though individual improvements correlate with clinical and angiographic success.
No takes yet. Share an insight, caveat, or question.
CABG may preserve rather than improve LV function at 6 months; leaves open whether angiographic success predicts clinical responders.
Harðarson et al. (1974) studied this question.
