[Analysis of 1,400 blood pressure profiles]
Insights
This study analyzed blood pressure profiles in 1,226 hypertensive patients, revealing age-related differences in hypertension types. Borderline hypertension, manageable without drugs, was noted in a significant percentage of patients.
Area of Science:
- Cardiovascular Medicine
- Hypertension Research
- Ambulatory Blood Pressure Monitoring
Context:
- Hypertension diagnosis relies on indirect, non-invasive blood pressure measurements.
- The DINAMAP device was used for automatic, 12-hour blood pressure monitoring.
- Analysis included percentage of abnormal values, average BP, and variability.
Purpose:
- To analyze blood pressure profiles in a large cohort of hypertensive patients.
- To identify demographic patterns in different types of hypertension.
- To characterize borderline hypertension and its prevalence.
Summary:
- Analysis of 1,400 profiles from 1,226 hypertensive and 174 normotensive patients.
- Predominant hypertension types differ by age: diastolic under 60, systolic over 60.
- Borderline hypertension observed in 34.5% (under 60) and 21.8% (over 60) of patients.
Impact:
- Identifies distinct age-related patterns in systolic and diastolic hypertension.
- Highlights borderline hypertension as a common subtype requiring monitoring, not necessarily medication.
- Provides data for understanding hypertension prevalence and management strategies across age groups.
Abstract:
Hypertension may be defined by 3 criteria obtained by indirect, non invasive, automatic measurement of blood pressure using the DINAMAP device analyses the profile obtained over a 12 hour period (one recording every fifteen minutes): percentage of abnormal values (BP greater than 160/95 mm Hg), average values of systolic, diastolic and mean BP, variability (standard deviation of means), The analysis was based on 1,400 profiles recorded from 174 normotensive and 1,226 hypertensive patients. The following observations were made: the largest group was that of patients with predominantly diastolic hypertension under 60 years of age (81.3 p. 100 vs. 18.9 p. 100 systolic hypertension) and predominantly systolic hypertension over 60 years of age (68.9 p. 100 vs. 31.1 p. 100 diastolic hypertension), borderline hypertension (between 1 and 20 p. 100 of pathological values) is observed in 34.5 p. 100 of hypertensive patients under 60 years of age, and 21.8 p. 100 of patients over 60 years of age. This form of hypertension may be managed without drug therapy but requires a control blood pressure profile at least once a year, the other groups of patients were much smaller: pure diastolic hypertension (4.8 p. 100 in the under 60's, 0.6 p. 100 in the over 60's); pure systolic hypertension (1/1,226 cases of hypertension), permanent hypertension (5.7 p. 100 in the under 60's and 4.4 p. 100 in the over 60's), paroxysmal hypertension (2.1 p. 100 in the under 60's and 5.6 p. 100 in the over 60's).(ABSTRACT TRUNCATED AT 250 WORDS)
