Cardiac disease in the dialysis patient: good, better, best clinical practice.
Proven strategies to reduce cardiovascular events and cardiac mortality in hemodialysis patients are given on the basis of pathophysiology. This is an overview of our clinical know-how acquired during the last 30 years. We try to answer the following questions: (1) how to reduce cardiovascular events and cardiac mortality in hemodialysis patients; (2) how to achieve regression of left ventricular hypertrophy, the most important predictor of sudden cardiac death; (3) how to manage iron status during full correction of renal anemia to prevent iron deficiency-induced reactive thrombocytosis, which is recognized to cause fatal stroke and cardiovascular thrombosis; (4) how to maintain responsiveness to erythropoiesis-stimulating agents during correction of renal anemia, thereby avoiding unnecessarily high doses and so reaching ultimate cost-effectiveness.


CONCLUSIONS
Normalization of renal anemia is not responsible for increased risk of cardiovascular events/cardiac mortality. The inability to adequately address iron status in hemoglobin normalization studies and the underprescription of effective cardiac/antihypertensive medication might explain the adverse outcome. Effective cardiac/antihypertensive medication, intensive iron therapy during normalization of hemoglobin, optimized correction of metabolic acidosis and supplementation of vitamins which are involved in the energy metabolism should be considered to significantly improve the outcome of hemodialysis patients.
