Do borderline hypertensive patients have labile blood pressure?
Annals of Internal Medicine
|April 1, 1981
Summary
Ambulatory blood pressure monitoring in borderline hypertensive patients reveals no increased lability compared to other groups. However, a wide range of elevated blood pressure percentages necessitates multiple measurements for accurate evaluation.
Area of Science:
- Cardiology
- Hypertension Research
Background:
- Borderline hypertension is characterized by fluctuating blood pressure readings.
- Understanding 24-hour ambulatory blood pressure patterns is crucial for diagnosis and management.
Purpose of the Study:
- To investigate the 24-hour ambulatory blood pressure patterns in borderline hypertensive patients.
- To compare blood pressure lability in borderline, normotensive, and fixed hypertensive individuals.
Main Methods:
- Sixty-three patients (21 normotensive, 21 borderline hypertensive, 21 fixed hypertensive) underwent noninvasive ambulatory blood pressure monitoring.
- Blood pressure was recorded every 7.5 to 15 minutes over a 24-hour period.
Main Results:
- Mean 24-hour blood pressures differed significantly across the three groups (p < 0.005).
- Standard deviations of blood pressure were not significantly different between groups.
- Borderline hypertensive patients showed an intermediate percentage of elevated blood pressures, with a broad range (7.9% to 81.2%) within the group.
Conclusions:
- Borderline hypertensive patients do not exhibit greater blood pressure lability than normotensive or fixed hypertensive individuals.
- The wide variability in elevated blood pressure percentages within the borderline group underscores the need for multiple measurements for accurate assessment.

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

4.6K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
