May refine mortality risk stratification via home monitoring; leaves open whether variability is modifiable or causal.
Does day-by-day variability of home blood pressure and heart rate predict cardiovascular mortality in a general population?
Day-by-day variability in home blood pressure and heart rate independently predicts cardiovascular, stroke, and cardiac mortality, highlighting its potential utility in routine cardiovascular risk assessment.
