Cautious adoption warranted from case data; leaves open confirmation of CABG effects on exercise LV function.
Does coronary artery bypass surgery improve left ventricular pump function in patients with severe effort angina and exercise-induced left ventricular dysfunction?
Successful coronary artery bypass surgery can significantly improve ischemia-induced left ventricular dysfunction during exercise.
