Evaluation of hypertension control among hemodialysis patients in Pakistan: a prospective follow-up study.

BACKGROUND

Hypertension is highly prevalent and uncontrolled among hemodialysis patients. In Pakistan published data does not provide enough information about the management and factors associated with uncontrolled hypertension in hemodialysis patients.

OBJECTIVE

This study was conducted to evaluate the factors influencing the pharmacotherapeutic management and control of hypertension in hemodialysis patients.

METHODS

A prospective follow-up study was conducted on hemodialysis patients who were enrolled at study sites between 1 June 2020 and 31 December 2020. The predialysis blood pressure (BP) readings were recorded as mean SBP and DBP at baseline and for each of 6 months. Multivariate analyses were applied to analyze the factors associated with uncontrolled hypertension in hemodialysis patients.

RESULTS

The average predialysis BP (SBP and DBP) of study participants at baseline visit was 158.41 and 87.22 mmHg respectively. After 6 months the study participants have 150.27 mmHg and 80.03 mmHg average predialysis SBP and DBP respectively. Only 28.1% of hemodialysis patients were on target BP after 6 months. Results of multivariate analysis have shown that the use of beta-blockers and calcium channel blockers (CCBs) were significantly associated with hypertension control at baseline [odds ratio (OR) = 1.432, P value = 0.034] (OR = 1.499, P value = 0.045) and at after 6 months (OR = 2.824, P value = 0.015) (OR = 1.883, P value = 0.032).

CONCLUSION

This study revealed that among the antihypertensive drugs, CCBs and beta-blockers provided better management in controlling hypertension among hemodialysis patients.
