Peripheral arterial disease (PAD) is a partial or complete occlusion of one or more arteries leading to a suppression of blood flow and ischemia. In the process of stenosis, numerous processes are described, among which, the most common being atherosclerosis, affecting the arteries of the inferior and coronary limbs. In the 60 patients investigated angio-coronarographically in the Emergency County Clinical Hospital of Sibiu with PAD, the prevalence of high blood pressure (HBP) and smoking was observed, among the risk factors, and 73.3% had one or more coronary lesions. The association of diabetes mellitus (DM) with PAD has shown an increase in the number of coronary lesions. There was also a strong positive correlation between the presence of left anterior descending artery (LAD) injuries and the stage of PAD regardless of other risk factors.
