Objectives: This study aimed to evaluate the level of adherence to medication among patients with ischaemic heart disease (IHD) in Oman and assess the related factors. Methods: This cross-sectional questionnaire-based study among patients with IHD attending the outpatient clinic at Sultan Qaboos University Hospital, Muscat, Oman, was performed between January and December 2021. Results: A total of 105 patients (mean age = 49.9 ± 11.1 years, 78.1% male) were recruited. Most of the patients (80%) reported taking the medications by themselves; 77 (73.3%) patients said that over the preceding 2 weeks, they had missed at least 3 doses of their medication. The reasons for missing the medications included forgetting (100%), having to take too many tablets (57%), feeling that the tablets are not effective (48%) and having to take the tablets too often each day (23%). The factors responsible for patients failing to take medications could not be identified. Conclusion: Medication adherence was low among patients with IHD in Oman, with high pill burden being the most common reason for non-adherence. Physicians must bear this in mind when reviewing patients.
