Key result
Elderly patients with essential hypertension had a significantly lower cardiac index during daytime compared to young or middle-aged patients (2.3 vs 3.2 L/min/m2, P<0.01).
Why the study?
How do systemic hemodynamics during sleep differ between young/middle-aged and elderly patients with essential hypertension?
Observational (n=24)
How do systemic hemodynamics during sleep differ between young/middle-aged and elderly patients with essential hypertension?
Absolute Event Rate: 2.3% vs 3.2%
p-value: p=<0.01
Elderly patients with essential hypertension exhibit a lower cardiac index during both daytime and sleep compared to younger patients, alongside a blunted reduction in cardiac index during sleep.

Does not support changing hypertension management in elderly patients; leaves open whether age-related sleep hemodynamics warrant prospective study.
Minamisawa et al. (1994) conducted an observational in Essential hypertension (n=24). Older age (elderly) vs. Young or middle-aged was evaluated on Cardiac index during daytime (p=<0.01). Elderly patients with essential hypertension had a significantly lower cardiac index during daytime compared to young or middle-aged patients (2.3 vs 3.2 L/min/m2, P<0.01).
