Abstract:
〈 b 〉 〈 i 〉 Objective: 〈 /i 〉 〈 /b 〉 There are few existing data on the status of coronary artery disease (CAD) in patients with atherosclerosis of the cerebral artery detected by brain imaging studies. We aimed to analyze the predictors of asymptomatic angiographically significant CAD detected by simultaneous cerebral and coronary angiography. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 This retrospective cohort study screened data obtained between August 2009 and April 2019; 11,047 patients underwent cerebral angiography for atherosclerotic change ( & #x3e;50% stenosis or aneurysm) seen in brain magnetic resonance angiography (MRA) or computed tomography angiography (CTA) at a single center by endovascular neurosurgeon’s decision. Of these, 700 patients including 622 patients who underwent simultaneous coronary and cerebral angiography and 78 patients who underwent coronary angiography within a month were enrolled. We investigated the characteristics and predictors of angiographically significant CAD ( & #x3e;50% stenosis). Furthermore, we also analyzed the major adverse cardiovascular and cerebrovascular events (MACCE), including all-cause death, myocardial infarction, and stroke for 5 years. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 The frequency of significant CAD was 59% (413/700), the mean age was 68.9 ± 10.3 years, and 60.6% were male. During mean follow-up of 50 months, the MACCE rate of our whole cohort was significantly higher in the CAD group (21.5%) than in the non-CAD group (14.6%; hazard ratio 1.65, 95% CI 1.17–2.33, 〈 i 〉 p 〈 /i 〉 value = 0.005). Considering that the embolic stroke is less associated with atherosclerotic change, our predictive model of significant CAD was made without embolic stroke ( 〈 i 〉 n 〈 /i 〉 = 599). In our multivariate model 2 including univariate & #x3c;0.1, the independent predictors of significant CAD were male (OR 1.62, 95% CI 1.11–2.35, 〈 i 〉 p 〈 /i 〉 = 0.012), diabetes mellitus (OR 1.81, 95% CI 1.22–2.68, 〈 i 〉 p 〈 /i 〉 = 0.003), previous stroke (OR 1.63, 95% CI 1.02–2.60, 〈 i 〉 p 〈 /i 〉 = 0.039), low ankle-brachial index (ABI; & #x3c;0.9; OR 3.25, 95% CI 1.21–8.73, 〈 i 〉 p 〈 /i 〉 = 0.019), left ventricular ejection fraction (EF) & #x3c;50% on echocardiography (OR 2.82, 95% CI 1.25–6.35, 〈 i 〉 p 〈 /i 〉 = 0.012), troponin I or T positive (OR 2.76, 95% CI 1.69–4.53, 〈 i 〉 p 〈 /i 〉 & #x3c; 0.001), and complex features on cerebral angiography (OR 2.73, 95% CI 1.78–4.19, 〈 i 〉 p 〈 /i 〉 & #x3c; 0.001). 〈 b 〉 〈 i 〉 Conclusions: 〈 /i 〉 〈 /b 〉 Accurate coronary evaluation by coronary angiography might be considered when patients with atherosclerotic cerebral artery detected on brain MRA or CTA planned cerebral angiography were male or have diabetes mellitus, previous stroke, low ABI ( & #x3c;0.9), left ventricular EF & #x3c;50% on echocardiography, troponin I or T positivity, and complex features on cerebral angiography.
