Coronary angiography in patients with kidney dysfunction and myocardial injury: A retrospective cohort study on management of myocardial injury in hospitalized patients with kidney disease

•Myocardial injury i.e. elevated cardiac troponins is common in hospitalized patients•Implications of elevated troponin remain uncertain in patients with kidney insufficiency beyond overt myocardial infarction•Probability of coronary angiography and revascularization declines with progressive kidney dysfunction•Revascularization benefit is curtailed with increasing kidney dysfunction
