Control of arterial hypertension in the context of metabolically-associated disease: challenges and opportunities in Ukraine

Abstract Background/Introduction Arterial hypertension is a prevalent, but modifiable cardiovascular (CV) risk factor. Effective control of blood pressure (BP) is associated with decreased rates of CV morbidity and mortality, as was convincingly demonstrated in randomized clinical trials. There is a substantial gap between BP control in clinical trials and real clinical practice due to multiple factors – e.g. lack of awareness, low medication compliance, side effects of medications, and insufficient availability of medical care – to name the few. The association between poor BP control and metabolically associated disease (MAD) like diabetes and obesity is widely acknowledged and considered the key challenge in effective management of arterial hypertension. Purpose To determine patterns of awareness and control of arterial hypertension in the context of MAD in Ukrainian outpatient patient sample. Methods We enrolled 309 subjects (108 with MAD and 201 without MAD). MAD was defined as the presence of type 2 diabetes and/or overweight/obesity. All subjects were consented for the structured interview and triple sitting BP measurement with an automated device. Results MAD-positive and MAD-negative groups were comparable by age (54.4±1.34 vs 51.8±1.2 years, p=0.29), systolic BP (141.3±2.0 vs 137.4±1.6 mm Hg, p=0.082), diastolic BP (85.2±1.2 vs 82.5±0.9 mm Hg, p=0.13). Presence of MAD was associated with increased odds of having BP>139/89 mm Hg (odds ratio [OR] 1.66, 95% confidence interval [CI] 1.04-2.67, p=0.035), better awareness on hypertension (OR 2.65, CI 1.64-4.28, p=0.0001), and less prevalent normotension (OR 0.51, CI 0.31-0.84, p=0.008). Among MAD-positive patients without history of HTN, 50% actually had elevated office BP, although it did not reach statistical significance as compared to MAD-negative subjects (OR 1.32 CI 0.68-2.56, p=0.42, see Picture 1). Less MAD-positive patients did not take any antihypertensive drugs (37.0% vs 56.7%, difference -19.7%, CI -8.03 to -30.51%, p=0.001), and more of them were taking 3 antihypertensive drugs (17.6% vs 7.5%, difference 10.1% CI 2.58-18.85. p=0.007). Only 53.7% of MAD-positive subjects and 39.8% of MAD-negative subjects claimed they were taking BP-lowering medications on a regular basis (p=0.02). There was no difference in achievement of BP control between MAD-positive and MAD-negative groups (39.2 vs 38.7% for subjects who were aware of HTN, 31.9 vs 31.3% of all hypertensive individuals, p=NS for both). More MAD-positive than MAD-negative subjects admitted they consume alcohol several times per week or daily (22.2 vs 12.4%, p=0.025). Conclusions MAD disease is associated with more prevalent HTN and better awareness on elevated BP. MAD requires more intensive BP-lowering therapy to achieve target BP, but the compliance to medications is suboptimal.Patterns of awareness and BP control
