BACKGROUND: Cardiovascular diseases determine overall mortality in patients with end-stage renal failure. Therefore, testing for myocardial ischemia is important. Elevation of cardio-specific troponins have been frequently measured in patients with end-stage renal failure. Thus, we studied systematically whether patients on chronic intermittent hemodialysis without overt coronary heart disease have increased ...

BACKGROUND: For patients with end-stage renal disease and their providers, dialysis unit-based cardiac arrest is the most feared complication of hemodialysis. However, relatively little is known regarding its frequency or epidemiology, or whether a fraction of these events could be prevented. METHODS: To explore clinical correlates of dialysis unit-based cardiac ...
