Key result
Chronic stroke in hypertensive patients linked to a ~4-fold higher prevalence of non-dipping BP.
Why the study?
The study was conducted to investigate the characteristics of 24-hour BP dipping patterns in hypertensive stroke patients.
Cross-Sectional (n=100)
No
Absolute Event Rate: 86% vs 22%
p-value: p=<0.001
Hypertensive patients with chronic stroke complications exhibit significantly higher rates of non-dipping blood pressure patterns and elevated night-time blood pressures compared to those without stroke.
May warrant ambulatory BP monitoring in hypertensive stroke survivors; leaves open whether targeting non-dipping alters outcomes.
Objective: We conducted a study titled for Investigation on the characteristics of 24-hour blood pressure (BP) dipping patterns in hypertensive stroke patients. Methods: Descriptive research, analysis, and comparison, the research was conducted from July 2019 to September 2020 at the Vietnam Heart Institute - Bach Mai Hospital. There are 100 patients diagnosed with idiopathic hypertension who were divided into two groups (without stroke complications and another group with chronic stroke complications > 6 weeks), both groups were similar in age (45-64 years old). Results: The daytime systolic BP (SBP) indices, 24-hour BP including SBP, diastolic BP (DBP), and mean arterial pressure (MAP), and particularly night-time BP indices were elevated in the stroke group compared with those without stroke complications (p < 0.05); there were no significant differences observed in daytime DBP and MAP between the two groups. SBP indices were higher in those with hemorrhage stroke compared with those with ischemic stroke, albeit without statistical significance. The prevalence of non-dipper was significantly higher in the stroke group compared with the non-stroke group (p < 0.001). Conclusion: The daytime SBP indices, 24-hour BP (SBP, DBP, MAP), and particularly night-time BP indices were elevated in the stroke group compared with those without stroke complications. The prevalence of non-dipper was significantly higher in the stroke group compared with the non-stroke group.

Pham et al. (2024) conducted a cross-sectional in Idiopathic hypertension (n=100). Chronic stroke complications vs. Without stroke complications was evaluated on Prevalence of non-dipper blood pressure pattern (p=<0.001). Hypertensive patients with chronic stroke complications had a significantly higher prevalence of a non-dipping blood pressure pattern compared to those without stroke (86.0% vs 22.0%, p < 0.001).
