Blood Pressure Control and Exaggerated Blood Pressure Response in Nigerians with Essential Hypertension
並列摘要
Abstract Background: Blood pressure (BP) control in hypertensives is important in preventing cardiovascular (CV) morbidity and mortality. This work was done to assess control of BP among Nigerian hypertensives at rest and during exercise. Materials and methods: A total of 85 male hypertensives were recruited consecutively and had clinical evaluation and treadmill (TM) exercise testing using the Bruce protocol. Independent t-test, chi-square, and Fisher’s exact tests were used to compare patients with controlled and uncontrolled BP using SPSS version 16 software. Adjustment for confounders was by logistic regression and general linear model. Results: Resting systolic BP (rSBP) (mmHg) and resting diastolic BP (rDBP) (mmHg) were significantly lower in the controlled group (115.0 ± 12.29, 133.1 ± 12.27, P =＜0.001 and 76.00 ± 6.55, 91.4 ± 8.00, P =＜0.001). The proportion of subjects with controlled BP was 37.7%. Adjusted peak SBP (PSBP) during exercise (mmHg) was significantly higher in the uncontrolled than in the controlled group (210.5 ± 27.31, 191.8 ± 20.77, P = 0.001). Adjusted exaggerated blood pressure response (EBPR) was found in 37 subjects (44%) in the uncontrolled group while seven subjects (0.1%) had EBPR in the controlled group (P = 0.003). Conclusion: This study shows that EBPR is significantly higher in subjects with uncontrolled BP compared with those with controlled BP. Therefore, good BP control may be the key factor in preventing EBPR in hypertensives.
