Abstract
Aim. The aim of this study was to assess the prevalence of cardiovascular risk factors among the Sharif University of Technologystudents. Background. Coronary Artery Disease (CAD) is a leading cause of mortality and disability in Iran and obesity is considered as one of the main causes. The primary prevention is a solution for prevention of this disease, especially from an early age. The studies regarding prevalence of cardiovascular risk factors are limited and unavailable in the university students especially in engineering students. Method. This cross-sectional study was conducted on 223 Sharif University of Technology students (150 male, mean age 20.33؛ and 73 female, mean age 20.36). Data were collected by using questionnaire, blood analysis and anthropometric measurements. Findings.The prevalence of overweight and obesity was 19.29% (male: 22.66%, female12.33%) and central obesity based on waist circumference index was 21.97% (male: 18%, female: 30.14%). Also, 60.09% of subjects were inactive and 43.5% had low HDL-C. High triglyceride levels and hypertension were observed in subjects (12.21% and 14.8%, respectively). There were at least two cardiovascular risk factors in 87% of subjects. There were positive correlations of body mass index with systolic blood pressure (r =0.224, P=0.0005) and triglyceride (r=0.147, P=0.014) and negative correlation between body mass index and HDL-C (r=-0.189, P=0.002). Conclusion. The results showed that the prevalence of cardiovascular risk factors is high among the students therefore, it is necessary to provide an appropriate evaluation and solution for prevention and health promotion.

Abstract
Abstract Aim. The purpose of this study was to determine the effect of -8week aerobic training on serum levels of high sensitivity C-reactive protein (hs-CRP) in high school male students with different Body Mass Indexes (BMI). Background. The low-grade chronic inflammation, which is characterized by increased levels of inflammatory markers in blood (such as CRP, Interleukin 6) is a strong risk factor for some chronic diseases. The hs-CRP is the most sensitive marker of inflammation and independent predicator of cardiovascular diseases and increase in hs-CRP levels are associated with obesity and cardiovascular diseases. The effect of aerobic training on hs-CRP of adolescents with different BMIs needs further investigation. Method. In this quasi-experimental study, 24 healthy and non-athlete boys (mean age, 16.33 and standard deviation, 0.47 years) were divided into three groups "thin, normal, and overweight or obese" according to their BMI. The training program included -8week (three sessions per week) progressive aerobic running at intensities of %75-60 of maximal heart rate. To determine changes in hs-CRP levels, the blood samples were collected before and after training program in the identical conditions. Findings. Training program had no significant effect on hs-CRP levels in all groups. There was a statistically significant difference in hs-CRP levels between obese group and the other two groups in esponse to training program, both before and after intervention. Conclusion. Eight-week aerobic training did not have a significant effect on hs-CRP of the subjects, likely due to insufficient intensity and duration of exercise training and low baseline hs-CRP levels. Decreased hs-CRP levels in obese group, compared with other groups, was likely due to the obesity status and higher baseline hs-CRP levels.

Abstract
Aim. This study aimed to determine predictive power of obesity indices, cardiovascular fitness and physical activity in the development of cardiovascular disease (CVD) in male and female college students. Background. Given the high mortality due to cardiovascular diseases from the young age caused by obesity and physical inactivity, the primary prevention, especially at an early age can be a solution to avoid the disease. Initial screening by simple, secure and affordable methods for prevention is essential. Method. A total of 223 students (150 males, age 20.33±1.71 and 73 females, age 20.36±1.72) participated in this cross-sectional descriptive study. Data were obtained using a questionnaire, anthropometric measurements, and cardiovascular fitness (VO2max). Independent t-tests was used to show difference between gender in terms of variables, ANOVA was used to determine the differences among groups of male and female separately, whose had the different number of risk factors, and Pearson and Spearman correlation coefficient were used to determine the correlation of obesity indices and VO2max with metabolic risk factors, and the ROC curves was used to measure the power of predicting and the cut-off points of cardiovascular risk factors. Findings.Statistically significant correlation was found between obesity indices and metabolic risk factors (other than blood glucose and systolic blood pressure in males). As the number of metabolic risk factors increased, elevation in obesity indices in females and the reduction of VO2max in males were significant. All obesity indices were within normal range. Cut-off points calculated by the ROC were 21.11 for body mass index and 75.15, 0.44 and 75.50, 0.47 for waist circumference and the waist-to-height ratio, for males and females respectively. Conclusion. The findings of this study showed that the obesity indices are more powerful than physical activity levels and VO2max for predicting the possibility of cardiovascular disease among students.

Abstract
Aim. The aim of this study was to assess the causes of dysfunctional ventilatory weaning response after cardiac surgery
Background. One of the most important complications after cardiac surgery is the prolonged mechanical ventilation, because it is associated with the increase in mortality (30-40%). Extubation of endotracheal tube within the 6 hours post operation is considered as a gold standard improving heart function, increasing patients’ comfort, decreasing respiratory complication, and decreasing cost and hospitalization. The prolonged mechanical ventilation and dysfunctional ventilatory weaning response (DVWR) are the risk factors for cardiac surgery and controlling and preventing them is necessary.
Method. This was a descriptive cross-sectional study in which 80 patients admitted to Cardiac Surgery Department of Imam Reza Hospital in Mashhad were selected within a 4 months period by convenience sampling method. Patients with mechanical ventilation over 6 hours were recruited. Data were analyzed in SPSS software.
Findings. DVWR was significantly associated with smoking (p=0.03), and delayed recovery from anesthesia was the most common reason associating with DVWR (55.3%).
Conclusion. By controlling factors of the DVWR, we can reduce the duration of mechanical ventilation.
