24 Jul 2025 • In heart failure (HF) patients, low nighttime systolic blood pressure (SBP) signals higher risk for adverse outcomes.

Using continuous pulse transit time monitoring, researchers followed patients for a median of 3 years (1,083 days), grouping SBP into tertiles: high (136 mm Hg), middle (117 mm Hg), and low (100 mm Hg).

Those in the lowest tertile faced the highest risk of HF hospitalization or cardiac death, with multivariate analysis showing over double the risk versus the highest group (HR 2.10).

Overly low nighttime SBP may be a key prognostic marker in HF care.
