Blood pressure control and its associated factors among patients with heart failure in Jordan

Uncontrolled blood pressure (BP) has been associated with increases risk of cardiovascular events including heart failure (HF). This study aimed to explore the factors associated with poor BP control among patients with HF attending two major outpatient cardiology clinics in Jordan. Variables including socio-demographics, biomedical variables, in addition to disease and medication characteristics were collected using medical records and custom-designed questionnaire. The validated 4-item Medication Adherence Scale was used to assess medication adherence. Binary logistic regression analysis was conducted to explore the significant and independent predictors of poor BP control among the study patients. Out of the 427 participants, 77% of were found to have hypertension as a comorbid condition. Regression analysis results revealed that being not satisfied with the prescribed medication (OR= 2.882; 95%CI 1.458-5.695; P<0.01), reporting moderate medication adherence (OR= 0.203; 95% CI: 0.048-0.863; P<0.05), not receiving digoxin (OR= 3.423; 95% CI 1.346-8.707; P<0.05), and not receiving aldosterone antagonist (OR= 2.044; 95% CI: 1.038-4.025; P<0.05) were associated with poor BP control. Future interventions should focus on increasing medication satisfaction and enhancing medication adherence, along with considering digoxin and aldosterone therapy in order to improve BP control among patients with HF.
