For instance, PCDH17 level was induced by lncRNA DCRF to aggravate autophagy and myocardial fibrosis in diabetic cardiomyopathy.[11] Also, PCDH17 is highly‐expressed in vascular smooth muscle cells of myocardial infarction.[12] However, whether PCDH17 affected CH and how its expression was altered and regulated in CH remain covered. This evidence concerns the gene PCDH17 and myocardial infarction.
