High salt intake in patients with kidney disease may mean heart trouble

(RxWiki News) For patients with kidney disease, too much salt could raise heart disease risk, a new study found.

This study, conducted by Tulane University researchers, looked at 3,757 patients with kidney disease during a median of just under seven years. Those who excreted the most sodium in their urine appeared to have a raised risk for heart disease, including problems like heart failure, stroke and coronary heart disease.

Past research has tied kidney disease to a raised risk of heart disease, and higher salt intake is tied to raised blood pressure, which is a  coronary heart disease risk factor, these researchers noted.

The researchers noted that, if more research confirms their findings, kidney disease patients' heart health may benefit from a reduction in sodium intake.

Talk to your doctor before making any big changes to your diet.

This study was published recently in JAMA.

The National Institute of Diabetes and Digestive and Kidney Diseases, Johns Hopkins University, the Clinical and Translational Science Collaborative of Cleveland and others funded this research. Researchers disclosed potential conflicts of interest involving pharmaceutical companies and medical device makers.
