Gensini scoring has been used to measure coronary artery lesion by using quantitative coronary angiography, in which different weights were applied for varied degrees of severity and the generated scores were closely correlated to degrees of coronary artery stenosis and blood supply.[27] The results of this study demonstrated that the relative expression level of the PIK3C2A gene is uncorrelated to the Gensini score, which indicates the severity of coronary artery lesions. The gene discussed is PIK3C2A; the disease is coronary stenosis.
