Diagnostic accuracy of computed tomography coronary angiography in patients presenting with heart failure of unknown etiology in the middle east

Objectives: The purpose of this study is to assess the diagnostic performance of coronary artery calcium score (CACS), computed tomography coronary angiography (CTCA), and the prevalence of coronary artery disease (CAD) as etiology of heart failure (HF) in the Middle Eastern population. Background: CTCA has several advantages compared to invasive coronary angiography (ICA). However, studies on the diagnostic accuracy of CTCA and CACS in detecting the prevalence of CAD in patients with newly diagnosed HF are lacking in the Middle East. Methods: This study included 204 patients with symptoms of HF and ejection fraction (EF) of
