Background: Coronary CT angiography (CTA) is an excellent tool for triage of acute chest pain (ACP) in the emergency department (ED). Limited data exist regarding its use for initiation of medical therapy, particularly in patients with nonobstructive coronary artery disease (CAD).
Methods: Patients presenting to the ED with ACP who underwent coronary CTA were divided into four groups according to stenosis severity: 0-25% stenosis, 26-50% stenosis, 51-70% stenosis and >70% stenosis. Prescription patterns of aspirin (ASA) and statins were analyzed before and after identification of CAD on CTA.
Results: Between 2009 and 2013, a total of 5,781 patients who presented to the ED with ACP underwent CTA (average age 49 +/- 9 years, 52% male). Risk factors included hypertension (35.6%), diabetes (7.7%), hyperlipidemia (33.6%) and current tobacco use (20.3%). Prescription of ASA and statins increased with increasing stenosis severity (Table 1). However, prescription of statins in the 26-50% stenosis category did not increase (36.2% vs. 35.9%, p=NS).
Conclusions: Coronary CTA in the ED can be utilized not only for ACP triage but to initiate medical therapy. The lack of increase in statin prescription for nonobstructive CAD demonstrates the need for education of ED providers to consider evidence-based therapy for prevention.
