Abstract

Although cardiovascular disease (CVD) is an important cause of death in patients on hemodialysis, evidence of a beneficial effect of percutaneous intervention (PCI) on stable heart disease is scarce. We investigated the cardiovascular outcomes of hemodialysis patients under our policy of encouraging coronary artery screening tests to the extent possible. A total of 147 hemodialysis patients have been treated in our clinic so far. In 98 of them, coronary artery screening tests were performed, three in unstable and 95 in asymptomatic patients. Significant coronary artery stenosis was detected in 29 at the first tests and in 11 during subsequent tests (40/98, 40.8%), and PCI or coronary artery bypass grafting (CABG) was performed. Multiple PCIs were needed in 21 patients. In the other 49 patients, coronary artery screening tests were not undertaken based on the nephrologist's decision or patient refusal. At the end of the study, 73 (74.5%) patients with tests, and 14 (28.6%) without tests were still outpatients (P < 0.01). Of 40 patients transferred to other hospitals for medical reasons or who died before transfer, there was cerebrovascular accident in eight, malignancy in six, congestive heart failure without CVD in four, infection in three, sudden cardiac death in one, and others 18. No patient with tests died of CVD and the only patient who died of sudden cardiac death probably due to myocardial infarction was a patient who had declined the screening tests. Coronary artery screening tests, intervention and subsequent periodic tests for asymptomatic hemodialysis patients can reduce the occurrence of cardiovascular events in this population.
