Abstract
Background: Coronary Artery Disease (CAD) is one of the leading causes of mortality
and morbidity all over the world. One of the most important predictors of outcome of patients with coronary aterey disease is the site of stenosis i.e. Proximal versus nonproximal stenosis. This study designed to evaluate the relationship between CAD risk factors and site of stenosis.
Methods: In this case- control study in the patients undergone coronary angiography (CAG) in Imam Khomeini Hospital, Tehran, Iran a total of 125 CAD patients with proximal lesion in CAG enrolled the study as case group and equal sex and age matched number of patients with non proximal lesion selected as control group. Two groups were compared based on presence or absence of DM, hypertension, hyper cholestrolemia, hypertriglyceridemia and cigarette smoking.
Results: Relative frequency of DM was 33.6% and 10.4% in case and control group respectively (p< 0.0001). Relative frequency in two groups were 33.6 vs 28.8% For HTN (p= 0.41), 30.4% vs 29.6% for hyper cholestrolemia (p= 0.89), 19.2% vs 16.8% for hypertriglyceridemia (p= 0.062) and 28.8 vs 39.2 for C/S (p= 0.08). Multivessle disease was significantly more prevalent in diabetics compared with non diabetic patients
89.1% vs 61% (p< 0.0001), no relationship was seen with HTN (p= 0.41), Hyper cholest- rolemia (p= 0.052) hypertriglyceridemia (p= 0.38) and cigarette smoking (p= 0.375). Conclusion: Proximal involvement of coronary arteries and multivessle disease in CAD patients is related to the history of DM but not to the history of hypertension, hypercholestrolemia, hypertriglyceridemia and cigarette smoking.

Abstract
Background: Transradial access is one of the main access techniques in angiography. This method is technically more difficult as it is associated with radial artery occlusion. Radial artery cannulation from the dorsal surface of the hand in the snuffbox area has been introduced as a suitable solution to overcome some of the disadvantages of the standard radial artery method. This study was conducted to compare the incidence of radial artery occlusion and other complications in the two methods.
Methods: This study was conducted on 100 patients Who were referred to the Imam Hospital in Ahvaz from 22 September 2020 to 19 Mach 2021. 50 patients underwent angiography with normal radial artery access and 50 patients underwent snuffbox angiography. Basic characteristics including age, sex, underlying disease (diabetes mellitus, hypertension, and dyslipidemia), family history of coronary artery disease, medical history including chronic coronary artery disease, stable ischemic heart disease, smoking, and LVEF, and also the length of hospital stay was also collected and recorded. All subjects in the two groups underwent radial artery ultrasound in the forearm and snuffbox 24 hours after angiography. Also, angiographic complications including radial artery occlusion (thrombosis), pain, hematoma and anesthesia were recorded.

Results: In the present study, the mean age in the two groups was similar (about 50-60 years). The distribution of sex, diabetes, weight, height and blood pressure was homogeneous in both groups. There was a statistically significant difference in the incidence of thrombosis and pain between the two groups. The results of this study showed that in the snuffbox angiography group, the number of uncomplicated cases was significantly more than the radial angiography group and in the snuffbox angiography group, the number of postoperative pain and thrombosis cases was significantly lower. The length of hospital stay in the Snuffbox group was shorter than the radial group, but there was no statistically significant difference.
Conclusion: Snuffbox angiography has fewer complications compared to the usual transradial method, so it can be used as a safe method for angiography.
