title: Effect of erythropoietin on ischemia tolerance in anemic hemodialysis patients with confirmed coronary artery disease.
abstract: From a total of 81 patients on maintenance hemodialysis who underwent coronary angiography, 8 patients fulfilled the criteria: significant coronary artery disease, hematocrit less than 27%, reproducible (ECG) positive treadmill test, no disturbance of repolarization in ECG at rest. Exercise stress testing was performed at a hematocrit of 25 +/- 2% and following erythropoietin therapy at a hematocrit of 34 +/- 0.5%. Symptom-limited exercise performance increased in all patients (1.10 +/- 0.3 W/kg b.w. vs. 1.44 +/- 0.31 W/kg b.w., p less than 0.01) as well as exercise duration (489 vs. 362 s, p +/- 0.01). ST segment depression during maximal exercise was reduced from a mean of 2.1 to 0.4 mm (p less than 0.01). It is concluded that amelioration of renal anemia by erythropoietin in dialysis patients with significant coronary artery disease reduces exercise-induced myocardial ischemia.
