Imaging and diagnostic testing: diastolic dysfunction after coronary artery bypass grafting: a frequent finding of clinical significance not influenced by intravenous calcium.

abstract：BACKGROUND:Myocardial infarction (MI) complicated by cardiogenic shock (CS) is associated with high mortality. Early coronary revascularization improves survival, but the optimal mode of revascularization remains uncertain. We sought to characterize practice patterns and outcomes of coronary artery bypass grafting (CAB...
