Abstract

Background: Despite significant efforts to improve the diagnosis and management of hypertension, the proportion of patients who fail to achieve target blood pressure control remains high. Uncontrolled hypertension and resistant hypertension are associated with an increased risk of cardiovascular complications. This study aimed to evaluate the prevalence and some associated factors of uncontrolled and resistant hypertension. Objective: To determine the prevalence and identify factors associated with uncontrolled and resistant hypertension at Can Tho University of Medicine and Pharmacy Hospital. Methods: A cross-sectional descriptive study was conducted on hypertensive patients attending the outpatient clinic of Can Tho University of Medicine and Pharmacy Hospital. Results: Among 247 hypertensive patients, the mean age was 62.3 ± 12.7 years, the majority were female (60.7%), and a high prevalence of comorbidities was observed, including diabetes mellitus (41.3%) and dyslipidemia (60.7%). The prevalence of uncontrolled hypertension was 55%, while resistant hypertension accounted for 9.3% of the total population and 16.9% among the uncontrolled group. In the uncontrolled group, most patients were treated with 2–3 antihypertensive agents but still failed to achieve the target, and approximately 20% were on monotherapy. No statistically significant association was found between uncontrolled/resistant hypertension and comorbid conditions (p > 0.05). Conclusion: The prevalence of uncontrolled hypertension at this tertiary hospital remains high, while resistant hypertension accounts for a smaller proportion but still represents a high-risk group. Suboptimal antihypertensive regimens and inadequate management of concomitant cardiovascular risk factors may contribute to poor blood pressure control. Optimizing multidrug therapy, improving treatment adherence, and conducting larger multicenter studies are necessary to clarify the associated risk factors in the Vietnamese population.
