Researchers find no link between dialysis treatments and cardiac symptoms

April 06, 2017

The researchers found no link between the timing of dialysis treatments and cardiac symptoms such as chest pains or emergency room admissions. A similar number of patients in each of the three groups experienced cardiac symptoms. However, the investigators identified several predictors that might indicate which dialysis patients have a particularly high risk of having a heart attack. These include the seriousness of the patient's condition, prior heart disease, high pre-dialysis potassium blood levels, and a large drop in potassium blood levels after dialysis.

"In conclusion, our study does not indicate that timing of dialysis poses a risk. What may be of greater importance is the potassium status, its treatment, and the severity of the patients' condition on admission," the authors wrote. "Given that this is a retrospective as well as a small study, we cannot make any clear recommendations, however our findings suggest that rather than delay dialysis, concern should be placed on the degree and rate that potassium levels change," they added.
