Figure 1From: Dual imaging stress echocardiography versus computed tomography coronary angiography for risk stratification of patients with chest pain of unknown originKaplan-Meier survival curves for two different groups of the patients based on calcium score (Ca-score) ≥ 100 and Ca-score < 100 (Up).Kaplan-Meier survival curves for two different groups of the patients based on the presence (>50%) or absence of coronary artery stenosis at CTCA of at least one coronary artery (in the medium).Kaplan-Meier survival curves for the two different groups of patients based on abnormal CFR on LAD (≤1.9) and/or wall motion score index change positive for stress-induced ischemia compared to patients with normal CFR on LAD (>1.9) without stress-induced ischemia (Down).Back to article page
