Effectiveness of a Pharmacist-Led Educational and Follow-Up Intervention on Blood Pressure Control Among Patients with Coronary Artery Disease: A Randomized Controlled Study

Abstract

Background: Effective blood pressure (BP) control matters for secondary prevention and it is one big piece of the cardiovascular (CV) morbidity story, alongside mortality inside the United States, especially for people with coronary artery disease (CAD). Interventions done by pharmacists might be beneficial to cardiovascular results, even if the details vary.
Objective: To see how well a structured, pharmacist-led education plus follow up approach works for reducing systolic and diastolic BP in patients diagnosed with CAD.
Methods: We conducted a prospective randomized controlled study with 330 patients who had CAD, 165 in the intervention group and 165 receiving standard care. The pharmacist provided counseling, education, lifestyle guidance and adherence support, plus follow up. BP outcomes were then evaluated using descriptive and comparative analyses.
Results: Compared with standard care, the intervention group (IG) had notably stronger reductions in SBP and DBP. For SBP the values were 6.3 vs. 3.6 mmHg, and for DBP 3.2 vs. 2.2 mmHg, with p <0.001. The mean decreases were 4.95 mmHg for SBP and 2.70 mmHg for DBP, correspondingly.
Conclusion: Pharmacist-led educational and follow-up efforts improved BP management among patients with CAD quite meaningfully, and they may support better secondary prevention outcomes too.
