The Gensini score was used to evaluate the severity of coronary artery stenosis. The CHD patients were categorized into a mild lesion group (<26 scores, 36 cases), a moderate lesion group (26-54 scores, 48 cases), and a severe lesion group (>54 scores, 36 cases) according to the Gensini score.
Coronary calcium score was found to have a significant correlation with the presence of coronary artery stenosis (r= 0.452, p < 0.001).
Previous studies have proposed several factors to be related to coronary collateral development, such as genetic factors, age, degree of coronary artery stenosis, the presence of total occlusion, myocardial ischemia, physical exercise, smoking, body mass index, hyperlipidemia, hyperhomocysteinemia, diabetes, and inflammation (17, 20-23).
Clinically significant but not critical coronary artery stenosis on CCTA is defined as the narrowing of the coronary artery diameter by 50% to 70% [62, 63].
About 16% to 30% of renal transplant recipients who have not undergone coronary angiography would die of cardiovascular event, and some patients cannot receive timely and effective treatment due to inadequate examination, leading to severe outcome.11 A study12 has confirmed that renal transplantation recipients with coronary artery stenosis are more likely to die if they receive conventional therapy using drugs compared to those who received revascularization (PCI or coronary artery bypass surgery).
The findings of our study suggest that selective antegrade graft cardioplegia delivery along with aortic root can provide superior myocardial protection because of more homogeneous distribution of cardioplegia solution and warm blood reperfusion through vein grafts to areas of critical coronary artery stenosis or complete coronary artery occlusion.

During severe artificial stenosis, the pressure at the distal coronary artery stenosis is significantly reduced and the rate of bleeding from the perforation site subsequently decreases.
In a recent substudy of the GULF-RACE registry, over 80% of khat users who presenting with acute coronary syndrome and underwent coronary angiography had significant coronary artery stenosis (3).
Table 2 shows the multivariate regression analysis for predictors for significant coronary artery stenosis. In multivariate logistic regression analysis to demonstrate factors associated with significant CAD lesions, age, presence of diabetes mellitus (DM), and smoking were significant predictors for the severity of CAD lesions; however, khat chewing did not show such association.
Washington, August 16 ( ANI ): A new study has for the first time established a link between high levels of urinary Bisphenol-A (BPA) - a controversial chemical commonly used in food and drink containers - and severe coronary artery stenosis (narrowing of the arteries).
