Description
Yue Zhang and co-authors study whether swings in blood pressure over time predict survival in elderly dialysis patients. Their 2023 paper follows 245 patients on maintenance hemodialysis for forty-six months. Patients are split into high and low groups by how much their systolic and diastolic pressures vary between visits.
Fifty-nine patients died during follow-up. Those with high systolic variability survived at a clearly lower rate than the steadier group. Diastolic variability showed no such link. Splitting by age sharpened the picture: the survival gap appeared in patients aged seventy-five and older, not in younger ones. The authors conclude that steady systolic pressure matters most for the oldest dialysis patients. They suggest variability deserves a place beside average pressure in routine care.
