Malfunctioning kidney

UESDAY, April 8 (HealthDay News) — Malfunctioning kidneys can cause a higher risk of sudden cardiac death in older women a U.S. study suggests.

Researchers’ studied; cases of 2,760 postmenopausal women with an average age of 67 and with a background of some heart disease even less serious, unidentified kidney function imperfections increased the risk of sudden cardiac death (SCD).They found the risk of SCD was 3.16 times higher in women with higher kidney dysfunction than in those with normal kidney function.

This increased risk was apparent after the researchers controlled for several basic risk factors including heart failure, age, smoking, heart rate and level of HDL.

Sudden cardiac death (SCD)

Out Of the 135 women who suffered SCD over 6.8 years, 36 (3.5 percent) had normal kidney function, 69 (4.6 percent) had fair kidney dysfunction, and 30 (13 percent) had higher kidney dysfunction.

Cardiac electrophysiology

Study author Dr. Rajat Deo, a fellow in cardiac electrophysiology at Johns Hopkins Hospital in Baltimore, said “We already know that patients with kidney disease have a higher risk of heart attack, heart failure and stroke.This study widens that concern to SCD and favors earlier suggestions that people with kidney disease be observed insistently for cardiac risk factors,”The study was published in the April 8 issue of Hypertension.
As these findings about a relation between kidney dysfunction and SCD were made in women, Deo and his colleagues believe they also relate to men.They’re planning an analysis of kidney function and SCD risk in elderly men and women.

End-stage kidney disease

SCD kills about 310,000 American adults a year and takes place when the heart suddenly and unexpectedly stops beating. SCD commonly strikes people with heart disease or heart disease risk factors, people with end-stage kidney disease and those with persistent kidney disease.
