[Diagnostic and prognostic aspects of home blood pressure measurement]
Insights
Home blood pressure monitoring is a popular diagnostic tool for hypertension. Diastolic readings over 90 mm Hg at home indicate pathological hypertension, warranting further study.
Area of Science:
- Cardiology
- Hypertension Research
- Diagnostic Tools
Context:
- Traditional hypertension diagnosis relies on infrequent office blood pressure (BP) measurements per World Health Organization (WHO) guidelines.
- Home blood pressure monitoring (HBPM) is increasingly utilized as a supplementary diagnostic method.
- HBPM aids in establishing daily BP profiles and identifying "white coat" hypertension.
Purpose:
- To evaluate the diagnostic utility of home blood pressure measurements.
- To define pathological values for self-recorded blood pressure readings.
- To identify borderline hypertension cases through HBPM.
Summary:
- Home blood pressure monitoring offers a more comprehensive view of a patient's BP than occasional office readings.
- Elevated home BP readings can identify patients with borderline hypertension who might otherwise be missed.
- The study suggests that diastolic home-recorded values exceeding 90 mm Hg should be considered pathological.
Impact:
- HBPM can lead to earlier and more accurate diagnosis of hypertension.
- This approach helps differentiate true hypertension from "white coat" effects.
- Further global epidemiological studies are needed to establish definitive normal and pathological values for HBPM.
Abstract:
Up to now the diagnosis of hypertension has been based on a few casual blood pressure measurements in the physician's office according to WHO guidelines. Blood pressure measurements at home in the recent years have gained increasing popularity as a supplementary diagnostic tool. The establishment of an everyday blood pressure profile and exclusion of "white coat" hypertension are the main diagnostic indications. In borderline hypertension those patients with elevated home blood pressures can be identified. However world-wide epidemiologic studies are urgently needed to develop definitions of normal and pathological values for self-recorded blood pressure readings. From our experience diastolic home-recorded values higher than 90 mm Hg should be regarded as pathological.
