Which Systolic Blood Pressure Measure Is Most Important for Determining Cardiovascular Risk: Seated or Supine Blood...

Area of Science:

• Cardiology
• Hypertension Research
• Preventive Medicine

Background:

• Current hypertension diagnosis relies on seated, non-invasive upper-arm cuff blood pressure (BP) measurements.
• Emerging evidence suggests supine BP measurements may offer additional insights into cardiovascular (CV) risk.

Purpose of the Study:

• To review recent findings on the impact of body posture on BP readings.
• To evaluate the influence of posture on CV risk prediction using office, ambulatory, and home BP monitoring.
• To discuss clinical implications and future research directions for supine BP measurement.

Main Methods:

• Review of recent studies on body posture and BP.
• Analysis of cardiovascular risk prediction across office, ambulatory, and home BP monitoring.
• Synthesis of clinical implications and future research needs.

Main Results:

• Supine-only hypertension in office BP monitoring (OBPM) is associated with CV risk comparable to hypertension in both seated and supine positions.
• Supine hypertension is a significant predictor of CV events, especially in individuals under 65.
• Nocturnal hypertension and abnormal dipping patterns in ambulatory BP monitoring (ABPM) are strong CV event predictors; supine nocturnal home BP monitoring (HBPM) is less studied.

Conclusions:

• Supine OBPM provides additional predictive power for CV risk assessment.
• Integrating supine BP data into composite risk scores and future outcome studies is recommended.
• Structured clinical application of supine BP measurement should be considered by guideline committees due to its prognostic benefits.
