Do daytime heart rate, blood pressure, and their products predict heart failure exacerbation and short-term mortality in patients with chronic heart failure?
Diastolic blood pressure and its product with heart rate may help stratify short-term risk of mortality and exacerbation in chronic heart failure.
Diastolic blood pressure, SBP × HR and DBP × HR products may be useful in sub- sequent heart failure exacerbation risk stratification. Moreover, DBP value may predict short-term mortality in patients with CHF.
Kowalczys et al. (Mon,) studied this question.
