Demographic and Clinical Characteristics of Patients Presenting With Angiotensin-converting Enzyme Inhibitors Induced Cough.

Introduction Angiotensin-converting enzyme inhibitors (ACEi) induced cough is still the greatest challenge in the continued utilization of ACEi for management of hypertension. The clinical pattern and related risk factors predisposing patients to ACEi-induced cough have not been studied in Pakistani hypertensive patients as yet. Hence, this study was conducted. Methods In this prospective, observational study individuals of both genders, of age 18 years or more, known cases of hypertension, taking ACEi, and having a chronic cough (>14 days) without any respiratory etiology were included. Their demographic and clinical characteristics were recorded. All data were managed using SPSS for Windows version 20.0 (IBM Corp., Armonk, NY). Results Enalapril was the most frequently prescribed ACEi (n=58; 47.2%) in patients with ACEi-induced cough followed by captopril (n=28; 22.7%), lisinopril (n=23; 18.7%), and ramipril (n=14; 11.4%). Higher body mass index (p=0.002), smoking (p=0.008), and longer time from the start of ACEi to the occurrence of cough (p=0.04) were the significant determinants of ACEi-induced cough. There were 33 (26.8%) participants who planned to request their physician to prescribe them an alternate medication due to their cough. Conclusions Enalapril was the most commonly ACEi prescribed among patients with ACEi-induced cough. Higher BMI, smoking, and longer time from the start of ACEi to the occurrence of cough related to ACEi-induced cough.
