Labile hypertension: a new disease or a variability phenomenon?

Area of Science:

• Cardiology
• Physiology
• Hypertension Research

Background:

• Blood pressure (BP) exhibits short- and long-term variability due to cardiovascular mechanisms and external factors.
• Both mean BP and BP variability (BPV) are implicated in cardiovascular (CV) events.
• Labile hypertension (HTN), characterized by sudden BP surges, is associated with adverse outcomes.

Purpose of the Study:

• To review and synthesize current research on BP variability (BPV).
• To elucidate the concept of labile hypertension (HTN).
• To assess the prognostic implications of BPV and labile HTN.

Main Methods:

• Literature review of recent evidence on BP variability and labile hypertension.
• Synthesis of findings related to the phenomenon of BPV.
• Analysis of studies investigating the prognostic value of these conditions.

Main Results:

• BPV is a significant factor contributing to cardiovascular events, independent of mean BP.
• Labile hypertension is increasingly recognized as a marker for increased CV risk.
• Evidence supports the prognostic importance of monitoring BP fluctuations.

Conclusions:

• BPV and labile HTN represent critical areas in cardiovascular risk assessment.
• Understanding these phenomena is crucial for predicting and potentially preventing CV events.
• Further research into the mechanisms and management of BPV and labile HTN is warranted.
