Coronary CT angiography for suspected acute coronary syndrome

<p>Aim: The optimal diagnostic test in the work-up of suspected acute coronary syndrome (ACS) may differ between men and women. The aim of this study was to compare sex-associated differences between using a diagnostic strategy including early coronary computed tomography angiography (CCTA) and standard of care (SOC). Methods: In total, 500 patients who presented with symptoms suggestive of ACS at the emergency department were randomised between a diagnostic strategy supplemented with early CCTA and SOC. Results: Women were generally older than men (mean ± standard deviation 56 ± 10 vs 53 ± 10 years, p &lt; 0.01) and were less often admitted to hospital (33% vs 44%, p = 0.02). Obstructive coronary artery disease on CCTA (&gt; 50% luminal narrowing) was less frequently seen in women (14% vs 26%, p = 0.02), and ACS was diagnosed less often in women (5% vs 10%, p = 0.03). Women underwent less outpatient testing when early CCTA was used in the emergency department evaluation of suspected ACS (p = 0.008). Conclusion: Women had a lower incidence of obstructive CAD on CCTA and were less often admitted to hospital than men. They were subjected to less outpatient testing when early CCTA was used in the emergency department evaluation of suspected ACS.</p>
