Clinical value of echocardiography combined with serum Cav-1, NFATc1, and PAI-1 in the diagnosis of Kawasaki disease complicated with coronary artery lesions.

To analyze the clinical value of echocardiography combined with serum lacuna protein-1 (Cav-1), activated T cell nuclear factor C1 (NFATc1), and plasminogen activator inhibitor-1 (PAI-1) in the diagnosis of Kawasaki disease (KD) complicated with coronary artery lesions (CAL). A total of 200 children with KD treated in our hospital from January 2019 to October 2021 were grouped as the KD alone group (n = 56) and the KD complicated with CAL group (n = 144) according to the results of coronary angiography. The levels of Cav-1, NFATc1, and PAI-1 were detected by enzyme-linked immunosorbent assay. Echocardiography was performed and the internal diameters of left and right coronary arteries were compared between the two groups. The area under the curve (AUC), sensitivity, and specificity of echocardiography combined with serum Cav-1, NFATc1, and PAI-1 in the diagnosis of KD complicated with CAL were analyzed with receiver operating characteristic (ROC) curve. Coronary angiography, as the gold standard, showed that the sensitivity of echocardiography in diagnosing KD with CAL was 88.19% (127/144), the specificity was 66.07% (37/56), and the accuracy was 82.00% (164/200). ROC curve analysis revealed that the AUC of KD complicated with CAL diagnosed by echocardiography, Cav-1, NFATc1, and PAI-1 was 0.819, 0.715, 0.688, and 0.663, respectively, and the AUC of combined diagnosis of the four was 0.896. The combination of echocardiography, Cav-1, NFATc1, and PAI-1 has high value in diagnosing KD complicated with CAL, which can be widely used in clinical practice.
