Uncontrolled Hypertension among Treated Hypertensive Patients

Objectives: To determine the prevalence of uncontrolled hypertension among Yemeni hypertensive patients on treatment. Methods: Cross sectional study was conducted among hypertensive adult patients presented to a private cardiac center in Sana’a from January to December 2016. All adult patients diagnosed to have hypertension for at least 3 months prior to the interview were included in this study. Each patient was clinically examined by training doctor on arrival to clinic and then every 3 months. The examination included; personal history, blood pressure, and through cardiovascular examination and recorded. Demographic data, special habits, body mass index, medication used and other laboratory data were registered. Collected data was coded and enter into Pc for statistical analysis. Results: The total number of patient with hypertension (HTN) presented into Cardiac Centre were 277. Of them 187 (67.5%) Were males and 90 (32.5%) were females, their age was ranged from 27 to 100 year with mean age of 57.5 ± 12.3. 61 patients (22.0%) had stage I hypertension (HTN) and stage II (HTN) was found in 182 Patients (65.7%). Of the total cases target BP controlled was achieved in 34 patients (12.3%). Several risk factors have been significantly associated with uncontrolled hypertension and these were; ischemic heart disease, elder age, left ventricular hypertrophy and renal impairment. There were no significant association between uncontrolled hypertension and other variables (Gender, Qat chewing, BMI, duration of hypertension and associated disease as diabetes mellitus, Cerebrovascular accident, medications & blood cholesterol level). Conclusion: Prevalence of uncontrolled hypertension was high in individuals with concomitant hypertension and comorbidity factors. IHD, renal impairment aging and left ventricular hypertrophy are the most important determinants of uncontrolled hypertension.
