The objective of this study is to analyze prescribing behavior of heart failure (HF) drugs and identify socioeconomic
factors affecting the medication adherence .Our study includes 90 HF patients with average age 59.4 ± 11.38 (34-80)
years.The average heart rate (HR) of HF patients was86.02 ± 15.2 (52-112) and average ejection fraction (EF) was
34.49 ± 8.11 (20-65). The mean number of days spent by an HF patient in hospital was 4.72 days (95%CI: 4.41 -
5.04).The patients with heart failure with reduced ejection fraction (HFrEF) were mainly prescribed withACEinhibitors
(76.67%),
ARBs
(42.22%),
Diuretics
(68.89%),
and
Beta-blockers
(54.44%).
Other
drug
categories
prescribed
included
Antiplatelets (41.11%), Anticoagulants (21.11%), Calcium channel blockers (31.11%), andInotropic agents
(24.44%).ACE-inhibitors and Diuretics were most popular drug categories withRamipril (C09AA05) and
Furosemide(C03CA01) being most frequently prescribed drugs, respectively. On average,15.28 drugs/patient (95%CI:
14.94 -15.62) were prescribed whereas, averageprescribed cardiovascular drugs/patient were only 8.24 (95%CI: 7.89 -
8.59). Poly-pharmacy was observed in 88.89% patients.According to thestudy dataset, a total of 1375 drugs were
prescribed to 90 subjects,of which 76.0% were given throughoral route and remaining24.0% through non-oral
routeincluding parenteral route (intramuscular (IM) and intravenous (IV)) and inhalational route. Charlson
Comorbidity Index (CCI)was calculated to estimate the 10-year survival rate. ACEI and Diuretics therapy were
considered as adherence indicators for HF medication over follow-up of 12 months and adherencerate was 74.44%
and 78.88%, respectively.
