Characteristics of 24‐h ambulatory blood pressure monitoring in elderly hypertensive males: An observational study of 85 year older patients

Abstract

Abstract Although hypertension is highly prevalent among the elderly and significantly contributes to cardiovascular disease risk, studies focusing on male elderly individuals over 85 years old are relatively scarce. This study aimed to investigate ambulatory blood pressure monitoring (ABPM) characteristics in male hypertensive patients aged over 85 years. These included demographic characteristics, antihypertensive drug use, 24‐h ABPM values, diabetes, coronary heart disease, sleep disorders, smoking history, and drinking history, and the differences in ABPM between the age groups over and under 85 years old were analyzed. A total of 585 elderly hypertensive patients were included. The mean systolic blood pressure in individuals aged over 85 years was significantly greater throughout the day (131.57 ± 12.52 mmHg vs. 123.75 ± 2.74 mmHg, p < .001). In the 85 years older age group, the nighttime variability coefficient of SBP was lower at 7.84 ± 2.9 than the under 85 years age group 8.92 ± 3.13 (p < .001). The 85 years older age group age group presented a significantly greater whole‐day systolic blood pressure standard deviation of ABPM (13.2 ± 3.19 vs. 12.47 ± 3.05, p = .005) compared with those under the age of 85 years. In the 85 years older age group, the proportion of individuals with the reverse dipper pattern was higher (48.15% vs. 38.31%, p = .017) than under 85 years age group. This study revealed that elderly male hypertensive patients aged over 85 years presented elevated average blood pressure levels. The research investigated ABPM characteristics. Older hypertensive individuals are more likely to have a reverse‐dipper blood pressure pattern.
