Background and objective: Cardiovascular disease is the leading problem of the elders. It is progressive disorder that is initiated in childhood and its clinical demonstration is revealed after middle-‌aged period. This study aimed to determine the relationship between coronary artery disease- related risk-factors and aging.
 Material and Methods: This‌ ‌descriptive‌-‌analytical study was conducted on all 772 elders referring to Kosar Angiography Center in Golestan province, 2008-‌2009. The subjects were divided into coronary disorder group and normal group. The risk factors including age, gender, body mass index (BMI), blood pressure, diabetes mellitus, smoking and drug addiction were assessed. The data was analyzed by SPSS‌-16, using Mann-Whitney and T-test.
Results: Most of the subjects were between 65 to‌ 75 years. Of the three main vessels, the most involved one‌ was circumflex (31.5%). ‌The factors such as gender and systolic hypertension were significantly different in two groups. Furthermore, the Risk ratio in the patients with ‌systolic hypertension (1.13 times) and the ones with diastolic hypertension (1.11 times) was more than normal group. Conclusion: Gender and systolic hypertension in the elders with CAD are the main and predisposing factors. Therefore, if we control hypertension, it may be possible to prevent from the CAD progress.

Background: Coronary angiography causes anxiety in patients and family that is a major cause of anxiety and lack of awareness. Choosing the right educational method is effective in increasing family awareness and support of patients. The present study aimed to compare the effects of Face-to-Face    and group education on awareness and anxiety of family members of candidates of coronary angiography
Methods: This randomized clinical trial study was conducted on 90 family members of candidates of coronary angiography at Amiralmomenin Hospital of Kordkuy as a referral center in Northeast of Iran in 2017. Eligible family member of patients was recruited through convenience sampling method and then allocated three; face-to-face education (A), group education (B), and control groups randomly. Family members in both intervention groups received same educational content about the method of performing coronary angiography, and the necessary care. The control group only received routine information. Data were collected using the Spielberger State-Trait Anxiety Inventory (STAI) and awareness questionnaire. SPSS Statistics for Windows, version x.0 (SPSS Inc., Chicago, Ill., USA). Software using descriptive statistics, paired t-test, Chi-square, Wilcoxon, and Kruskal-Wallis tests. The significance level was considered less than 0.5
Results: The score of anxiety and awareness in patients’ family members were not significantly different in the three groups before the intervention. After intervention, the mean scores of anxiety were 42.12±4.71 and 42.37±5.53 in the participants of group A and B respectively, and it was significantly different from the pre-intervention score (P<0.001). The mean awareness score was significantly higher in group B than in the other two groups (P<0.001)
Conclusion: According to the results, group education was more effective than face-to-face education in increasing awareness and reducing anxiety in families. We suggest developing programs in this regard
