The effect of hemodialysis (HD) on left ventricular (LV) function and exercise tolerance were measured at rest and during exercise using gated equilibrium radionuclide ventriculography in seven patients with confirmed coronary artery disease (CAD). To separate the effects of fluid removal rate on LV function in CAD, we investigated the same patients with identical overall volume loss of 4 liters during two different treatment times (4 hr and 2 hr). HD significantly increased resting LV ejection fraction (EF) from 55.7 +/- 8% to 64.7 +/- 8% (P less than 0.01) during the 4 hr HD and from 58.1 +/- 9 to 68.1 +/- 10 (P less than 0.05) during the 2 hr HD. Indicating ischemia, EF decreased at pre- and postdialysis peak exercise without differences between both treatments. HD also resulted in an improved segmental wall motion score. Exercise duration as well as S-T segment depression and angina score improved during HD, whereas heart rate, blood pressure and double product remained unchanged. We conclude that HD improves global and regional resting LV function and exercise tolerance in patients with CAD. The degree of interdialytic hydration and not the degree of fluid removal per time affects LV performance in CAD. Since LV function is the major prognostic factor in CAD, those patients require volume restriction and/or shorter interdialytic phases.
