Abstract
Introduction
Real-world evidence on the risk of angioedema associated with angiotensin-converting enzyme inhibitors (ACEIs) in patients with heart failure (HF) is scarce.
Objective
This non-interventional study aimed to estimate the incidence of and risk factors for angioedema in patients with HF initiating an ACEI in real-world practice.
Methods
This was a retrospective cohort study using claims data from the PharMetrics Plus database, supplemented with consumer health data, from 1 January 2007 to 31 March 2015. Patients with HF initiating an ACEI were followed up for a maximum of 1 year, until the first occurrence of angioedema or until cohort exit. Angioedema incidence rates were estimated and stratified by potential risk factors such as race, age, sex, and time from initiation of ACEI therapy. For each risk factor, the unadjusted and adjusted hazard ratio (HR) was calculated; exploratory analyses were carried out to account for all potential confounders.
Results
We identified 21,639 patients with HF initiating an ACEI (mean age 58 years; 35.6% women; mean follow-up 205 days). The 1-year incidence of angioedema per 1000 patient-years was 3.3 [95% confidence interval (CI) 2.4–4.5]. The incidence was higher in Black [6.2 (95% CI 3.1–12.5)] than in non-black [2.9 (95% CI 2.1–4.1)] patients, higher in women [5.2 (95% CI 3.4–7.9)] than in men [2.3 (95% CI 1.5–3.6)], and greatest in the first 30 days of ACEI therapy.
Conclusions
The risk of angioedema in patients with HF initiating an ACEI observed in this study is in line with published estimates for the general patient population treated with ACEIs.
