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

Uncontrolled blood pressure (BP) has been associated with increased risk of cardiovascular events including heart failure. This study aimed to explore the factors associated with poor BP control among patients with heart failure at 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. 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: 22 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, in order to improve BP control among patients with heart failure.

Automated summary

This study aimed to explore factors associated with poor blood pressure control among heart failure patients in Jordan. Variables including demographics, biomedical variables, disease characteristics, and medication adherence were collected. Regression analysis revealed that dissatisfaction with prescribed medication, moderate medication adherence, not receiving digoxin, and not receiving aldosterone antagonist were associated with poor blood pressure control. Future interventions should focus on increasing medication satisfaction and enhancing medication adherence to improve blood pressure control in heart failure patients.
