Oxygen uptake efficiency slope, a new submaximal parameter in evaluating exercise capacity in chronic heart failure patients.

abstract：BACKGROUND:Prior studies have reported race and sex differences in cardiac catheterization use after acute myocardial infarction (AMI). It is unclear whether race or sex differences in procedure refusal may contribute to this difference. We sought to determine whether cardiac catheterization refusal rates differ by pat...
