Abstract
Background & Objectives: Usually, among the candidate patients for cardiac valve's surgery, the coronary artery angiography is performed according to their age and gender. By this research, the prevalence of coronary artery disease is studied in addition we have tried to consider the risk - factors of coronary artery disease to predict the probability of coronary artery disease among them. Methods: we studied prospectively a population of 320 patients (144 male and 176 female) who were candidate to cardiac valve's surgery and underwent preoperative angiography in the cath - Lab of Imam Khomeini hospital in Tehran, from April - 1999 to October - 2003. Result: There was aortic valvulopathy in 131 patients, mitral in 90 and combined Mitro-aortic in 99. Angina was present in 35% and coronary artery disease risk factors in 27.8% of patients. The prevalence of coronary artery disease was 13.1 %. The prevalence of coronary artery disease in patients with angina was significantly higher (22.3% versus 8.2% in patients without angina). In addition the prevalence of coronary artery disease was significantly higher in patients with coronary artery disease risk factors (22.5% versus 9.5% in patients without risk factors). Three predictive factors of CAD in these patients were age, presence of angina pectoris and presence of CAD risk Factors. The prevalence of CAD in patients who have neither angina nor risk factors was 4.6%. In this group of patients no male under 60 years old and only 3.5% of female patients under 65 years old had coronary artery disease. Conclusion: The study showed that due to the low prevalence of coronary artery disease in patients with none of the coronary risk factors or without angina, we can avoid preoperative coronary angiography in males under 60 years old and females under 65 years old who have neither angina nor risk factors of CAD.

Abstract
Background & Objective: Electrocardiography is a useful method in predicting coronary artery occlusion site, left ventricular function and the prognosis of patients with acute myocardial infarction. Accurate localization of coronary artery occlusion and the extent of ischemic area are very important in decision making for invasive procedures to restore coronary perfusion. Methods: In this prospective study the abnormal findings of first recorded electrocardiogram in 100 patients with acute myocardial infarction w ere compared with coronary angiography findings and the value of ST-T changes in predicting coronary artery occlusion site was evaluated. Results: In acute anterior wall infarction, ST elevation in aVR (p=0.001), right bundle branch block (p=0.001) and ST depression in V5 strongly predicts LAD occlusion at its proximal part. Also ST depression, especially equal or more than 1 mm, in inferior leads indicates proximal LAD occlusion. The absence of such ST depression in these inferior leads correlates with distal LAD occlusion (p=0.01).ST depression of aVL also is a sign of distal LAD occlusion (p=0.01).In acute inferior wall infarction ≥ 1 mm ST depression in leads I, aVL and greater ST elevation in lead III than lead II refers to RCA involvement. Conclusion: In acute anterior myocardial infarction electrocardiography can help to differentiate proximal LAD lesion from its distal involvement. Also it is useful in determining the culprit vessel in acute inferior wall infarction and helps to recognize high risk patients with major benefit from invasive reperfusion strategies.

Abstract
Background & Objectives : Nowadays, coronary artery disease is the most common cause of death in developed countries and in the whole world. According to the WHO reports, it will be the main cause of death in 2020. Myocardial infarction is the most common diagnosis among hospitalized patients in industrialized countries. This disease causes more mortality and morbidity than others. Coronary artery bypass grafting surgery (CABGS) is one of the common treatments for ischemic heart disease but it may have some complications. In this study we wanted to evaluate the incidence of CABGS complications in Imam Khomeini Hospital of Ardabil in the first month after CABG. Methods: This study was a cross sectional analytic descriptive type and performed on all of the patients underwent CABGS in Imam Khomeini Hospital during 2011-2012. All of the data from patients (like demographic, past medical history, physical exam findings, paraclinical findings and CABGS complications) were inserted in special forms after gathering, and analyzed by SPSS v.16. Results: In this study, 211 patients were studied. About 145 (68.72%) of them were male and 66 (31.28%) were female. Seventy patient (33.17%) were more than 70 years old. About 33.22% of patients had a history of cigarette smoking and 9.95% were opioid abused. The 34.12% of patients had hypertension (HTN) history, 40.28% diabetes mellitus (DM), 17.06% history of hyperlipidemia and 63.98% had a history of the previous MI. Chest pain was the most common complication among the patients (93.36%). According to our study the prevalence rate of post CABGS complications were: bleeding after surgery 13.27%, postoperative myocardial infection 8.05%, neurological disorders 12.32%, renal complications 2.36%, respiratory symptoms 11.37% and 34.59% for cardiovascular complications. Also the total mortality was 5 (2.36%) persons. The data analysis showed that there was a significant relationship between sex with survival status, local infection and neurological disorders, and also there was a significant relationship between age with post CABGS survival, bleeding after surgery and renal complications. There was also a significant relationship between DM and post CABGS survival, local infections and respiratory complications and between HTN and local infections. Conclusion: According to the results of this study, the most common post CABGS complications were cardiovascular complications, especially arrhythmias.

Abstract
Background & objectives: Most of coronary angiography patients have not enough information about undergoing procedure . This lack of knowledge makes anxiety in patients and thereby changes their vital signs. There is no study regarding the effective education of patients based on their native language. This study was done to investigate the effect of video education in native language on vital signs caused by anxiety of patients undergoing coronary angiography.
Methods: This quasi experimental study was done in 2013 on 160 patients undergoing angiography in Imam Khomeini Hospital in Ardabil. Participants were divided into two groups randomly (80 in each group): case (native video education) and control groups. The sheets of hemodynamic variables were completed in determined time intervals for data collection. ANOVA with repeated measures and Chi square were used to analyze the data in SPSS13 software. P-value<0.05 was considered statistically significant.
Results: The results of repeated measures ANOVA showed significant improvement in vital sign variables except for temperature in both groups over the time (p<0.05). And there was significant difference in the mean vital sign variables in determined time intervals (p<0.05).
Conclusion: Video education in native language decreases the vital signs in coronary angiography patients. Therefore the video education especially in native language is recommended for improving vital signs before invasive procedures.
