Optimal Medical Therapy for Secondary Prevention of Acute Coronary Syndrome: A Retrospective Study from a Tertiary Hospital in Sudan

Abstract

Background Five-medication regimen is recommended for patients after acute coronary syndrome (ACS) as a secondary prevention strategy at discharge to reduce recurrence and improve mortality. Objective This study aimed to assess prescribing of optimal medical therapy (OMT) as five-medication regimens for secondary prevention at discharge after ACS in Sudan. Methods A retrospective cohort study was performed at a tertiary hospital located in Wad Medani, Sudan, in the period between January and December 2019. Data were collected from patients’ files. OMT was defined as a combination of five medications; aspirin and P2Y12 inhibitors, statins, beta-blockers (BBs), and angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) or if a valid contraindication was documented. Results Of the 619 patients throughout the study period, 591 were selected based on inclusion and exclusion criteria. The median age of patients was 60 years, and 58.9% of patients were male. Diabetes (44.5%) and hypertension (42%) were the most common risk factors. Most patients (58.4%) were diagnosed with ST-segment elevation myocardial infarction. About 99.7% of patients were on aspirin, 99.5% on statins, 97% on clopidogrel, 96.8% on dual antiplatelet therapy, 70.4% on BBs, and 57.9% on ACEIs/ARBs. OMT for secondary prevention was prescribed to 267 (45.2%) patients with ACS at discharge. Conclusion Although prescriptions for all five guideline-recommended medications after ACS were suboptimal, the study showed a positive trend in prescribing most individual medications.

During hospitalization, moderaterisk individuals with biochemical signs of infarction usually undergo angiography and revascularization [5,24]. Saudi Arabia's 2030 vision is to enhance healthcare systems by collecting appropriate data in order to meet and manage challenges, implement preventative measures, and increase access to healthcare systems.…”
