Coronary artery disease incidence, risk factors, awareness, and medication utilization in a 10-year cohort study. BMC Cardiovasc Disord 2024; 24:101. [PMID: 38347457 PMCID: PMC10863377 DOI: 10.1186/s12872-024-03769-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Accepted: 02/04/2024] [Indexed: 02/15/2024] Open
Abstract
BACKGROUND There is a substantial disparity in coronary artery disease (CAD) burden between Iran and other nations that place a strong emphasis on the assessment of CAD risk factors and individuals' awareness and ability to control them. METHODS Two thousand participants of a community-based Iranian population aged 20-74 years were investigated with a mean follow-up of 9.9 years (range: 7.6 to 12.2). An analysis of Cox regression was conducted to determine the association between CAD development and classic risk factors such as age, sex, smoking, physical activity, education, obesity, dyslipidemia, hypertension, and diabetes mellitus. Furthermore, we computed the population attributable fraction for these risk factors. RESULTS After a follow-up period of nearly 10 years, 225 CAD events were reported, constituting 14.5% of the overall incidence. Nighty three percent of participants had more than one risk factor. Age was the most predictive risk factor, with a hazard ratio (HR) and confidence interval (CI) of 5.56 (3.87-7.97, p < 0.001) in men older than 45 and females older than 55 compared to lower ages. In comparison to females, males had an HR of 1.45 (CI: 1.11-1.90, p value = 0.006) for developing CAD. Nearly 80% of the patients had dyslipidemia, with a hazard ratio of 2.19 (CI: 1.40-3.44, p = 0.01). Among the participants, 28.9% had hypertension, and 52% had prehypertension, which had HRs of 4.1 (2.4-7.2, p < 0.001) and 2.4 (1.4-4.2, p < 0.001), respectively. Diabetes, with a prevalence of 17%, had an HR of 2.63 (CI: 2 -3.47, p < 0.001), but prediabetes was not significantly associated with CAD. Awareness of diabetes, dyslipidemia, and hypertension was 81%, 27.9%, and 48.1%, respectively. Regarding medication usage, the corresponding percentages were 51% for diabetes, 13.2% for dyslipidemia, and 41% for hypertension. CONCLUSIONS Compared to previous studies in Iran and neighboring countries, the current study found a higher incidence of CAD, more prevalent risk factors, and a lower awareness and ability to control these risk factors. Thus, an effective preventive strategy is needed to reduce the CAD burden in Iran.

[PMID: 38028716 PMCID: PMC10590463 DOI: 10.34172/jcvtr.2023.31834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Accepted: 08/04/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction Genetic and environmental factors are involved in the pathogenesis of cardiovascular diseases (CVDs). The aim of the study was to investigate between the genotype of the NFKB1 gene and the cardiometabolic risk factor in patients undergoing coronary angiography. Methods This cross-sectional study was conducted on 462 adults (male and women) aged between 35 and 75 years who referred to Afshar Hospital for coronary angiography in 2021- 2022. The polymerase chain reaction restriction fragment length polymorphism method was used to detect the genotype of rs28362491. Biochemical parameters were measured using commercial kits. Gensini and Syntax scores were calculated using the angiography result to assess the extent of coronary artery stenosis. We used multivariate logistic regression analysis to examine the relationship between genotype variants and cardiometabolic risk factors. Results There was no association between variant genotypes and abnormally levels of serum alanine aminotransferase (ALT) (P value=0.51), aspartate aminotransferase (AST) (P value=0.99), triglyceride (TG) (P value=0.48), total cholesterol (P value=0.79), low density lipoprotein-cholestero (LDL-C) (P value=0.31), high-density lipoprotein-cholesterol (HDL-C) (P value=0.53), fast blood sugar (FBS) (P value=0.39), systolic blood pressure (P value=0.14), diastolic blood pressure (P value=0.64), Gensini score (P value=0.48) and syntax score (P value=0.74) in the crude model even after adjustment for confounding factors. Conclusion We found no association between the ATTG polymorphism and cardiometabolic risk factors in patients who had coronary angiography. Further investigations are needed to assess the association between variants of 28362491 and cardiometabolic markers.

Interaction of dietary patterns with rs28362491 on severity of coronary artery stenosis in patients undergoing coronary angiography. Sci Rep 2023; 13:14608. [PMID: 37669998 PMCID: PMC10480227 DOI: 10.1038/s41598-023-41438-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Accepted: 08/26/2023] [Indexed: 09/07/2023] Open
Abstract
Coronary artery disease (CAD) is one of the most important cardiovascular diseases. Lifestyle and genetic factors play important roles in the development of CAD. The aim of the study is to examine the interaction of dietary patterns and genes on the likelihood of abnormal lipid profile and coronary artery stenosis in Iranians undergoing coronary angiography. This cross-sectional study was performed on 440 patients who underwent coronary angiography. The factor analysis method was used to extract dietary patterns. Commercial kits have been used to assess biochemical parameters. The detection of the rs28362491 genotype was carried out by the method of restriction fragment length polymorphism. Traditional (TDP) and western dietary pattern (WDP) were extracted. We observed an interaction of adherence to TDP and rs28362491 on the odds of having a high Gensini score. These interactions indicated that higher adherence to TDP was associated with higher odds of having a high Gensini score for patients with DD genotype than for those with II genotype. (OR 2.33, 95%CI 1.00-5.44; P = 0.05). These interactions remained statistically significant even after confounder variables. We observed an interaction between higher adherence to TDP and rs28362491 variants on the odds of high low-density lipoprotein cholesterol levels (P = 0.04) in the unadjusted model. We found a significant interaction of this polymorphism and higher adherence to WDP on the odds of having a high Gensini score in the unadjusted model (P = 0.04). This study provides a basis for future research on NF-KB1 gene and diet interaction. More large-scale longitudinal studies are needed to validate these findings.

An innovative model for predicting coronary heart disease using triglyceride-glucose index: a machine learning-based cohort study. Cardiovasc Diabetol 2023; 22:200. [PMID: 37542255 PMCID: PMC10403891 DOI: 10.1186/s12933-023-01939-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Accepted: 07/24/2023] [Indexed: 08/06/2023] Open
Abstract
BACKGROUND Various predictive models have been developed for predicting the incidence of coronary heart disease (CHD), but none of them has had optimal predictive value. Although these models consider diabetes as an important CHD risk factor, they do not consider insulin resistance or triglyceride (TG). The unsatisfactory performance of these prediction models may be attributed to the ignoring of these factors despite their proven effects on CHD. We decided to modify standard CHD predictive models through machine learning to determine whether the triglyceride-glucose index (TyG-index, a logarithmized combination of fasting blood sugar (FBS) and TG that demonstrates insulin resistance) functions better than diabetes as a CHD predictor. METHODS Two-thousand participants of a community-based Iranian population, aged 20-74 years, were investigated with a mean follow-up of 9.9 years (range: 7.6-12.2). The association between the TyG-index and CHD was investigated using multivariate Cox proportional hazard models. By selecting common components of previously validated CHD risk scores, we developed machine learning models for predicting CHD. The TyG-index was substituted for diabetes in CHD prediction models. All components of machine learning models were explained in terms of how they affect CHD prediction. CHD-predicting TyG-index cut-off points were calculated. RESULTS The incidence of CHD was 14.5%. Compared to the lowest quartile of the TyG-index, the fourth quartile had a fully adjusted hazard ratio of 2.32 (confidence interval [CI] 1.16-4.68, p-trend 0.04). A TyG-index > 8.42 had the highest negative predictive value for CHD. The TyG-index-based support vector machine (SVM) performed significantly better than diabetes-based SVM for predicting CHD. The TyG-index was not only more important than diabetes in predicting CHD; it was the most important factor after age in machine learning models. CONCLUSION We recommend using the TyG-index in clinical practice and predictive models to identify individuals at risk of developing CHD and to aid in its prevention.

Effectiveness of Online Versus Telephone Counseling of Rational-Emotional-Behavioral Therapy on Sexual Function of Women Undergoing Cardiac Rehabilitation: A Randomized Clinical Trial:. Galen Med J 2022; 11:e2396. [PMID: 36698690 PMCID: PMC9838114 DOI: 10.31661/gmj.v11i.2396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Indexed: 01/27/2023] Open
Abstract
Background:Sexual function in patients with cardiovascular disease (CVDs) is often associated with anxiety and irrational beliefs. Moreover, 60-78% of patients with CVDs report sexual problems. Some studies suggest that sexual counseling is necessary for these patients but is not usually provided for them. Online or telephone counseling may be helpful during the covid-19 pandemic, but studies on its application to sexual function appear to be limited. This study aimed to investigate the effectiveness of online vs. telephone counseling of rational-emotional-behavioral therapy (REBT) on the sexual function of women undergoing cardiac rehabilitation. Materials and Methods: In this randomized clinical trial study, 46 women diagnosed with CVDs under rehabilitation were assigned into online and telephone groups. Overall, eight 60-min intervention sessions were held (once a week). The Female's Sexual Function Index (FSFI) questionnaire was completed by the women at baseline, week 8th, and follow-up week 12th (main outcome). Results: FSFI scores between the two groups at baseline (online: 13.28±2, telephone: 12.68±1.52, P=0.254) compared to week 12th (online 28.86±2.44, telephone, 26.6±2.10, P=0.002) were significantly different. As for within-group comparison in baseline compared to week 12th statistically significant difference was observed in all subscales of FSFI (P=0.05). Conclusion: Online and telephone REBT counseling can improve the sexual function of women undergoing cardiac rehabilitation, but online counseling appears to be more effective. Thus, this method is recommended to improve the sexual function of these women during the covid-19 pandemic. [GMJ.2022;11:e2396].

Abstract
Background: Obesity and overweight are important public health problems which are rapidly growing throughout the world. This study aims to provide 10-year incidence estimates of obesity and overweight in adults along with their risk factors in an Iranian adult population.
Methods: This cohort study was conducted within the framework of the Yazd Healthy Heart Project (YHHP) throughout phases from 2005-2006 to 2015-2016 among urban adult population. The participants comprised of 1000 males and 1000 females aged 20-74 years from urban areas of Yazd. Cox proportional hazards model was used to examine the potential risk factors for obesity and overweight.
Results: A total of 2000 participants aged 47.09 ± 16.97 years and body mass index (BMI) of 21.99 ± 2.21 kg/m2 were entered in this study at baseline. After 10 years of follow-up, the cumulative incidence of overweight for the entire population was 38.6% (41.6% in women and 36.8% in men). Furthermore, the 10-year cumulative incidence of obesity was 14.8% in the population (20.8% for women and 10.5% for men). Female participants showed a significantly higher incidence rate compared to males either for obesity or overweight. Regarding risk factors, there was a significant association between non-smoking (HR= 1.54, 95% CI: 1.06-2.25), socio-economic status (HR= 1.82, 95% CI: 1.13-2.94), and education (HR= 1.56, 95% CI: 1.14-2.13) with overweight (P < 0.05).
Conclusion: This study revealed the incidence rate of obesity and overweight is significantly high in adult population of Yazd, Iran especially in women. The most important predictors of overweight seem to be smoking, lower socio-economic status, and education.

[PMID: 35903309 PMCID: PMC9315257 DOI: 10.1177/11782218221112502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Accepted: 06/21/2022] [Indexed: 11/17/2022]
Abstract
Background: Lapse has been one of the major challenges in the treatment of drug dependence sometimes leading to its relapse. Objectives: The aim of this study was to determine the lapse rate in drug dependent patients as for the 2 methods of methadone maintenance treatment (MMT) and buprenorphine maintenance treatment (BMT) in Yazd city. Methods: In this cross-sectional study, 626 female and male patients who had referred to 5 SUD treatment centers in Yazd and had been treated with methadone and buprenorphine maintenance were studied. Participants were divided into 2 groups of MMT and BMT and were evaluated based on lapse within 6 months. Results: In this study, 60.9% of patients were treated with methadone but the rest were treated with buprenorphine. Overall, 33.1% of patients lapsed (35.2% for methadone and 29.8%for buprenorphine). Lapse in methadone treatment was correlated with age, occupational status, and duration of treatment ( P < .05); it failed to correlated with any other demographic and clinical characteristics ( P > .05). Lapse rate in buprenorphine treatment was also related to marital status and the drug used ( P < .05). The mean dose of buprenorphine consumed showed no significant relationship with lapse ( P > .05). The results demonstrated that given the low dose, lapse stood higher in the buprenorphine group than the methadone group; however, as to high dose, the buprenorphine group showed lower lapse than the other group. Conclusions: In regard with the high rate of lapse, it is recommended to consider the factors related to the 2 methods of treatments, and provide counseling and training programs to lower lapse in the patients.

Abstract
BACKGROUND Coronary artery disease (CAD) is a major problem in Iran as well as throughout the globe, and coronary artery bypass grafting (CABG) surgery is an appropriate option for many patients with symptomatic and severe CAD. The main purpose of this study was assessment of the short and long-term outcomes of patients undergoing CABG in Yazd Province, Iran. METHODS This historical cohort study examined the mortality rates of patients who had undergone CABG in Afshar Hospital in Yazd from 2011 to 2013. During this period, 2510 patients undergoing CABG were entered into the study and then followed for in-hospital and long-term mortality. RESULTS Mean age of the patients was 61.37 ± 10.50 years and 34.1% were women. In-hospital mortality turned out to be 3.7% and age over 70, left ventricular (LV) dysfunction, female gender, and left main (LM) involvement induced significant higher in-hospital mortality. Of all the patients, 84.1% were followed for a period of 41 ± 20 months. The survival rate proved to be 92.4% in one year and 82.9% in five years. The patients with age over 70, diabetes mellitus (DM), and LV systolic dysfunction (LVSD) showed significant lower survival rate, whereas the patients with utilization of left internal mammary artery (LIMA) demonstrated significant higher survival rate. CONCLUSION In-hospital and long-term mortality rate of patients undergoing CABG surgery is acceptable in comparison with other studies and more effort is needed into making this event a success.

Abstract
Background Due to the controversy over the effect of serum testosterone levels on coronary artery diseases, this survey explores the serum levels of free testosterone, luteinizing hormone, and follicle-stimulating hormone in candidates for coronary artery bypass graft compared with an age-matched control group and evaluates the associated factors in these participants.
Objective To determine the testosterone level in elective coronary artery bypass grafting participants. Materials and Methods In this cross-sectional study, all male patients aged > 40 yr as candidates for elective coronary artery bypass grafting, who were referred to the Afshar Hospital, Yazd, Iran, from March 2018 to March 2019, were included. In total, 100 men were enrolled (50 cases and 50 controls). Their serum levels of free and total testosterone, luteinizing hormone, and follicle-stimulating hormone were measured and the results were compared. Results The findings indicated a significant difference between the two groups in total and free testosterone (both p < 0.001); they were lower in the case group. There was also a significant difference in the total testosterone of the participants with diabetes mellitus compared with no-diabetic individuals (p = 0.007). Free testosterone of diabetic subjects taking insulin was lower compared with those taking no insulin (p = 0.04). There was also an association between the body mass index and free testosterone, left ventricular ejection fraction and total testosterone, and a significant and negative relation between the duration of hospital admissions and free testosterone (p < 0.05). Conclusion This study illustrates that participants with coronary artery disease bear a significantly low testosterone level in comparison with the healthy control group.

Abstract
Background The population attributable risk (PAR) percent has used widely in public health policy. We aimed to calculate the attribute risk of hypertension due to hyperuricemia by Levin's formulas compare to direct PAR calculation method. Methods This was a sub-study of Yazd Healthy Heart Cohort (YHHC). Overall, 1256 normotensive individuals were enrolled through multistage randomized cluster sampling and followed up for mean 9.8 years, from 2005-2015. The threshold cutoff point of the hyperuricemia was considered equal and more than 75th percentile that equal to 5.5 mg/dl for men and 4.3mg/dl for women. To calculate the attributable risk of hyperuricemia in developing hypertension, two methods were applied. Levin's formulas and direct PAR estimation by population risk calculation via exposure prevalence weighted formula. Multiple logistic regression was used for estimate of odds ratio (OR) of hyperuricemia in developing hypertension. We calculated Relative Risk (RR) from OR. The data were analyzed using SPSS software version 16. A significant level of 0.05 was considered. Results Hypertension developed in 44.7% of individuals with uric acid level ≥ 75th percentile vs. 35.6% of other individuals (P=0.024). Attributable risk (AR) of hyperuricemia in hypertension incidence was 9.1%. PAR of hyperuricemia for hypertension incidence by using two methods mentioned before was 6%, 5.8% respectively. Conclusion The results of the study confirmed the noticeable contribution of hyperuricemia as an independent other risk factor for the occurrence of hypertension. PAR of hyperuricemia for hypertension incidence by using two methods almost near was 6%, 5.8% respectively.

Abstract
Myocardial infarction (MI) is one of the leading causes of death in the world. Epidemiological studies have shown that dietary flavonoids are inversely related to cardiovascular morbidity and mortality. The study aimed to determine whether quercetin supplementation can improve inflammatory factors, total antioxidant capacity (TAC) and quality of life (QOL) in patients following MI. This randomized double-blind, placebo-controlled trial was conducted on 88 post-MI patients. Participants were randomly assigned into quercetin (n = 44) and placebo groups (n = 44) receiving 500 mg/day quercetin or placebo tablets for 8 weeks. Quercetin supplementation significantly increased serum TAC compared to placebo (Difference: 0.24 (0.01) mmol/L and 0.00 (0.00) mmol/L respectively; p < .001). TNF-α levels significantly decreased in the quercetin group (p = .009); this was not, however, significant compared to the placebo group. As for QOL dimensions, quercetin significantly lowered the scores of insecurity (Difference: -0.66 (12.5) and 0.00 (5.55) respectively; p < .001). No significant changes in IL-6, hs-CRP, blood pressure and other QOL dimensions were observed between the two groups. Quercetin supplementation (500 mg/day) in post-MI patients for 8 weeks significantly elevated TAC and improved the insecurity dimension of QOL, but failed to show any significant effect on inflammatory factors, blood pressure and other QOL dimensions.

Abstract
BACKGROUND AND OBJECTIVE Overweight and obesity are thought to be associated with increased risk of chronic disease in the Middle East. The present study aimed to determine the association between dietary habits and the incidence of overweight and obesity in urban adult population in the central part of Iran after a 10-year follow-up. METHODS This cohort study was initiated with 2000 participation aged 20-74 years from Yazd city in Iran based on Yazd Healthy Heart Project (YHHP). The participants without overweight and obesity at the baseline of the study were followed up to 10 years. Demographic data, anthropometric measurements, behavioral and metabolic risk factors of cardiovascular diseases and dietary habits were assessed at baseline and phase II. RESULTS After a 10-year follow up, 516 non-overweight and 1068 non-obese participants were included for the final analysis. Once adjustments were made for all potential confounders including age, sex, smoking, economic status, physical activity and education, it was identified that lack of weight control increased the risk of obesity (hazard ratio; 95% CI) in total population (1.9; 1.06, 3.4), as well as the risk of overweight (2.39; 1.07, 5.27) and obesity (2.65; 1.13, 6.25) in men. Moreover, consumption of mayonnaise increased the 10-year risk of overweight in women (6.09; 1.2, 30.99). CONCLUSIONS As revealed by the present study, unhealthy dietary habits can increase the incidence of overweight and obesity in central part of Iran. Therefore, changing the lifestyle appears to be urgent in reducing the risk of overweight and obesity.

Abstract
Objective: Hormones consumption in women who conceive through in vitro fertilization (IVF) as well as embryonic manipulations have raised concerns regarding the neonates’ health, including the possibility of pulmonary hypertension. This study, therefore, aimed to assess the pulmonary arterial pressure in at-term IVF neonates. Materials and Methods: This prospective cross-sectional study was conducted between March 2013 and October 2017 and compares 160 IVF neonates (group 1) with 160 naturally conceived neonates (group 2). The neonates in both groups were cesarean newborns, matched in terms of gestational and neonatal age. The neonates were three-seven days old, had a full-term gestational age of 37-39 weeks and 6 days, and a normal birth weight of 2500-4000 gr. The systolic pulmonary artery pressure (SPAP) was estimated using real-time echocardiography on the basis of peak flow velocity of tricuspid regurgitation jet. Results: A significant difference was observed in the mean SPAPs between the two groups (p<0.001). Although, the effect of gestational age on reducing SPAP was greater and statistically significant in group 1, the gradual decrease in the PAP after birth appeared to be slower in this group. Moreover, in both groups, the effect of gestational age on reducing SPAP was more convincing than that of the neonatal age. Further, in both groups, a significant reverse correlation was observed between the SPAP and the neonatal weight; however, it appeared to be markedly higher in group 1. Conclusion: Our study renders IVF as being culpable in the incidence of pulmonary hypertension among neonates. Hence, to detect the likelihood of pulmonary arterial hypertension in IVF neonates, it is recommended to monitor their PAP during the neonatal period, and thereby facilitate them with the required treatment.

Age-, sex-, and height-based blood pressure reference charts, Yazd children 6-18 years, Iran. Clin Exp Pediatr 2020; 63:321-328. [PMID: 32689764 PMCID: PMC7402986 DOI: 10.3345/cep.2019.00094] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2019] [Revised: 02/01/2020] [Accepted: 03/05/2020] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Pediatric hypertension is the main cause of morbidity and mortality in pediatric populations. PURPOSE To examine pediatric hypertension in a clinical setting, we used the percentile rank approach and defined hypertension as that above the 95th percentile. METHODS The present study was linked to the a national analytical cross-sectional community-based Iranian Children and Adolescents' Psychiatric Disorders (IRCAP) survey. The survey was nationwide and funded by the National Institute of Medical Research Development. The IRCAP survey included 31,000 children and adolescents aged 6-18 years in all 31 Iran provinces. The current study included 1,035 children and adolescents and linked the data of the risk factors of cardiovascular disease only in Yazd province via random cluster sampling. RESULTS Of the total participants, 456 (44.1%) were male and 579 (55.9%) were female. The mean age was 11.2±3.8 years (11.7±3.7 years for males, 11.0±3.6 years for females), while mean height was 146±20.0 cm overall, 147.2±22.0 cm for males, and 144.6±17.0 cm for females (P=0.009). The blood pressure distributions and percentiles were evaluated. CONCLUSION Here we determined age- and height-specific 50th, 90th, 95th, and 99th percentiles of systolic and diastolic blood pressures in Yazd boys and girls using 10-cm height intervals.

Abstract
BACKGROUND To investigate the relationship between the location of accessory pathways, electrophysiologic characteristics, and ablation success in Wolfe-Parkinson-White (WPW) syndrome. METHODS Electrophysiologic study was performed in 178 patients for a pre-excitation syndrome. Accessory pathway location, anterograde or retrograde conduction, ablation success, and recurrence rate were evaluated. RESULTS Among 178 patients with WPW syndrome, the most frequent location of the accessory pathway was left lateral (39.3%) which had high ablation success rate (97%) and low recurrence rate (1%). A meaningful relationship exists between accessory pathway location and electrophysiologic characteristics. Ablation success rate was 89.7% and was statistically related to accessory pathway location. Recurrent occurred in 2.9% of our patients and was more frequent in right free wall and PJRT. CONCLUSIONS The location of accessory pathways has a great impact on conductivity, ablation success, and recurrence rate in WPW syndrome.

Abstract
Infective endocarditis (IE) can be diagnosed using the Duke criteria, which cannot be conclusive especially when the results of blood cultures are negative. This study aimed at using real-time polymerase chain reaction (PCR) technique to isolate bacteria present in whole blood samples of patients with definitive IE on the basis of the method designed in this study. This laboratory and test study was conducted on 20 whole blood samples taken from patients with definitive IE. Real-time PCR of the 16s rRNA was utilized to directly analyze whole blood samples to diagnose bacterial IE. Of 20 whole blood samples with definitive IE, only one blood culture (5%) was positive and the isolated bacterium belonged to Streptococci viridans group. Also, 13 whole blood samples were positive using real-time PCR technique. The isolated bacteria were Enterococcus faecalis with seven (35%) cases, Streptococcus gallolyticus with two (10%) cases, Streptococcus mutans with one (5%) case, Streptococcus sanguinis with one (5%) case, Streptococcus salivarius with one (5%) case, and Staphylococcus aureus with one (5%) case. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) using real-time PCR technique were 65%, 100%, 100%, and 74%, respectively. The developed real-time PCR method allows us to detect bacteria in whole blood samples and is much more sensitive than culturing method. It also permits the differentiation of the main group of bacteria within a few hours for IE.

Abstract
Broad-range bacterial rDNA polymerase chain reaction (PCR) followed by sequencing may be identified as the etiology of infective endocarditis (IE) from surgically removed valve tissue; therefore, we reviewed the value of molecular testing in identifying organisms' DNA in the studies conducted until 2016. We searched Google Scholar, Scopus, ScienceDirect, Cochrane, PubMed, and Medline electronic databases without any time limitations up to December 2016 for English studies reporting microorganisms involved in infective endocarditis microbiology using PCR and real-time PCR. Most studies were prospective. Eleven out of 12 studies used valve tissue samples and blood cultures while only 1 study used whole blood. Also, 10 studies used the molecular method of PCR while 2 studies used real-time PCR. Most studies used 16S rDNA gene as the target gene. The bacteria were identified as the most common microorganisms involved in infective endocarditis. Streptococcus spp. and Staphylococcus spp. were, by far, the most predominant bacteria detected. In all studies, PCR and real-time PCR identified more pathogens than blood and tissue cultures; moreover, the sensitivity and specificity of PCR and real-time PCR were more than cultures in most of the studies. The highest sensitivity and specificity were 96% and 100%, respectively. The gram positive bacteria were the most frequent cause of infective endocarditis. The molecular methods enjoy a greater sensitivity compared to the conventional blood culture methods; yet, they are applicable only to the valve tissue of the patients undergoing cardiac valve surgery.

Abstract
BACKGROUND Medication errors which can cause several medical malfunctions, have been in the spotlight recently. Job satisfaction and fatigue seems to be related to the increase of medication errors in nursing. OBJECTIVE This study aimed to determine the correlation between the amount and type of medication errors with job satisfaction and fatigue of nurses working in Shahid Sadoughi hospital in Yazd-Iran. METHODS This is a descriptive study by a cross-sectional and correlational approach conducted on all the nurses working in an educational hospital who have characteristics of samples. Participants were 170 nurses working in Shahid Sadooghi hospital in Yazd, Iran in 2012. The questionnaires of demographic characteristics, medication administration error and nurses' job satisfaction and fatigue by purposive sampling were used for gathering data. Validity and reliability were checked for internal consistency and stability. Data were analysed by SPSS version 17 using Pearson correlation coefficient and Independent-samples t-test. RESULTS The findings did not illustrate a significant relationship between job satisfaction and fatigue with medication errors. Among the demographic characteristics, age of nurses was significantly associated with the frequency of medication errors (p=0.037). However, others were not significantly correlated (p>0.05). CONCLUSION In spite of the findings, based on no significant statistical relationship between job satisfaction and fatigue with the type and amount of medication errors in nursing, the effect of these variables on medication errors cannot be disregarded; thus further studies in this area are suggested.

Abstract
Background: Infective endocarditis (IE) is a microbial infection of heart valves and its endothelial lining which is considered as a life-threatening disorder. This study evaluated the epidemiological, clinical, and microbiological features of IE at the Cardiovascular Research Center in Yazd, Iran. Methods: The cross-sectional study was conducted on 20 patients diagnosed with definite IE on the basis of Duke’s criteria hospitalized for one year in the Cardiovascular Research Center in Yazd, Iran, from January 2015 to December 2015. Demographic information, clinical, laboratory, and microbiological findings, and also trans-esophageal echocardiography (TEE) of each patient were recorded and assessed. The collected data were analyzed using SPSS 16. Results: The mean age of the patients under study was 45±16 years with most of the afflicted patients (60%) being male. Most cases (70%) of IE were observed in the warm seasons (spring and summer). The most common clinical sign (80%) was fever. TEE was positive for all (100%) patients, and vegetation was seen in all patients. The nosocomial mortality rate was zero. However, 14 (70%) patients underwent surgical treatment. The valves afflicted with IE were: the mitral valve (40%), the aortic valve (35%), and the tricuspid valve (25%), respectively. 4 patients (20%) had a positive history of IE. Blood culture test was positive only in 1 case and the isolated microorganism belonged to the viridans group streptococci. Conclusion: Despite the one-year high prevalence of IE in this study, the nosocomial mortality rate was not high and was reported to be nil under surgical and antimicrobial therapy.

Abstract
BACKGROUND Doppler sonography is a type of sonography used for imaging the blood flow in the vessels and heart. This technique uses ultrasound waves with high frequency. In some patient candidates for venous graft, the identification of the suitable vein is not possible with clinical examination. OBJECTIVE This study compared the effects of preoperative color Doppler sonography of lower extremity veins on the postoperative outcomes of saphenectomy. METHODS This randomized clinical trial was conducted on 100 candidates of an off-pump coronary artery bypass graft (CABG) hospitalized in Afshar Hospital in Yazd in 2015. Patients were divided into two groups: 50 patients in the study group and 50 patients in the control group. Patients in the study group underwent color Doppler sonography of lower extremity veins using the Medison 8000 Live device. Patients in the control group were assessed preoperatively by routine venous examination without undergoing color Doppler sonography. The prepping and draping methods and also the preoperative antibiotics were the same for both groups. The patients were assessed for wound infection, edema, hematoma, and DVT 2 days, 1 week, and 1 month after surgery. Data were analyzed by SPSS version 16 using t-test, Chi-square, and Fisher's exact test. RESULTS The length of incision for saphenectomy was 29.20 ± 3.71 cm in the Doppler group and 28.98 ± 3.72 cm in the non-Doppler group with no significant difference between the two groups (p=0.768). The two groups were not significantly different with respect to age, gender, diabetes, hypertension, hyperlipidemia, smoking, and history of peripheral vessels disease, postoperative infection, postoperative organ edema, postoperative hematoma, and postoperative DVT. CONCLUSION Preoperative color Doppler sonography of the saphenous vein before saphenectomy has no effect on reducing the postoperative complications, and saphenectomy on the basis of intraoperative examination of the vein course by the surgeon has acceptable consequences. CLINICAL TRIAL REGISTRATION The trial was registered at the Thai Clinical Trials Registry (TCTR) (http://www.clinicaltrials.in.th) with the TCTR ID: TCTR20160708001.

Abstract
Background Chest pain is a common symptom for referring patients to emergency departments (ED). Among those referred, some are admitted to hospitals with a definite or tentative diagnosis of acute coronary syndrome and some are discharged with primary diagnosis of non-cardiac chest pain. This study aimed at investigating 30 days' adverse outcomes of patients discharged from ED of a major heart center in Iran. Methods Out of 1638 chest pain admissions to the centre during 2010–2011, 962 patients (mean age= 50.9±15.9 years) who were admitted to Afshar Heart Center's ED with chest pain as their chief complaint, and discharged with primary diagnosis of non-cardiac chest pain, were followed for any adverse cardiac events 30 days post discharge. The adverse events were: unstable angina, non-ST-elevated myocardial infarction (NSTEMI), ST elevated myocardial infarction (STEMI), coronary revascularization (percutaneous angioplasty, coronary artery bypass grafting) and death. Results Adverse cardiac events, including acute coronary syndrome (ACS), revascularization and death were observed in 30 patients (3.1%) including: acute MI n=5 (0.5%, sudden cardiac death inn=1 (0.1%, coronary revascularization in n=8 (0.8%) and hospitalization due to unstable angina/NSTEMI in n=16 (1–7%). Adverse events were seen more frequently in patients with history of hypertension, dyslipidemia and previous coronary artery disease. In univariate analysis, the chance of postdischarge adverse cardiac events was higher in patients with hypertension (OR=9.36, CI=3.24–27.03), previous coronary artery disease (OR= 3.8, CI=1.78–8.0), dyslipidemia (OR=3.5, CI=1.7–7.38) and discharge against medical advice (OR=2.85, CI= 1.37–5.91). Conclusion The extent of adverse cardiac events in patients with a primary diagnosis of non-cardiac chest pain within 30 days of discharge was significant, mandating nation-wide registries to provide better care for these patients.

Abstract
BACKGROUND Atrial septal defect (ASD) is a common congenital heart disease. OBJECTIVES The aim of this study was to assess the clinical course of ASD, as well as its frequency of spontaneous closure and regression of diameter. METHODS In a study conducted from 2000 to 2011, 192 consecutive patients with an isolated ASD were followed up regularly with periodic echocardiographic evaluations according to a standardized protocol. The study was conducted in two series of patients: infants and children and adults. Infants were classified into three groups based on ASD diameter: small (≤ 5 mm), medium (6 - 9 mm), and large (> 9 mm). In the same manner, the ASD size in children and adults was categorized into three groups: small (≤ 10), medium (10 - 20 mm), and large (> 20 mm). RESULTS The patients consisted of 76 (39.6%) males and 116 (60.4%) females. The mean age of patients at diagnosis was 16.12 ± 15.66 years (range 1 week - 75 years). The mean follow-up duration was 70 ± 9 months (range: 25 - 119 months). The most prevalent age group was adult patients (> 20 years), and most ASDs were of medium size (1 - 2 cm). The most common complication was mild pulmonary hypertension (31 cases, 16.2%), and Eisenmenger phenomenon was the rarest complication (2 cases, 1%). Overall spontaneous closure of ASD occurred in 42 (21.9%) cases. Spontaneous closure in cases with small defects occurred in 18 of 22 (81%) infants and 24 of 81 children > 1 years of age. Regression of ASD size occurred in 2 (9.5%) infants and 3 (3.7%) children. No spontaneous closure was observed in cases with a defect size > 10 mm, and no spontaneous occlusion was detected in adolescents or adults. Seventy-two percent (n = 139) of patients needed surgical repair or transcatheter closure of the ASD. CONCLUSIONS It is concluded that atrial septal defects < 6 mm typically close spontaneously, and ASDs measuring 6 - 9 mm may regress in infants and children. An ASD > 1 cm has little chance of spontaneous closure and may need surgical or device closure. ASD diameter and age at diagnosis are the most important predictors of spontaneous closure and the need for possible surgical or device closure.

Abstract
Background The arterial ductus is a major communicative pathway which is naturally patent in the fetus, connecting the body of the major pulmonary artery to the descending aorta. Although usually closing on its own, the patent ductus arteriosus (PDA) may remain open in the second postnatal week due to a lack of prompt diagnosis in the initial days of life or an absence of prompt treatment. Objectives To prevent the untoward sequelae of patency of the ductus arteriosus, and to avoid invasive surgery at higher ages, the researchers in the present study embarked on determining the effects of oral ibuprofen during the second postnatal week on newborns with patent ductus arteriosus. Patients and Methods In this study, 70 neonates aged eight to 14 days, presenting at Khatam-al-Anbia clinic and the NICU ward of Shahid Sadoughi hospital in Yazd, Iran, who were diagnosed with PDA through auscultation of heart murmurs and echocardiography, were randomly assigned to two groups. The experimental group received oral ibuprofen of 10 mg/kg in day 1, 5 mg/kg in day 2, and 5 mg/kg in day 3 administered by their parents. The control group did not receive any drug. Parents were informed of the potential drug complications and side effects and asked to report them to the researchers if any occurred. Results After intervention, the patent ductus arteriosus was closed in 62.9% of the neonates in the experimental group (35 newborns) who received oral ibuprofen, while it was closed in 54.3% of the control neonates (35 newborns) who did not receive any drug (P = 0.628). No complications were observed in either of the neonatal groups. Conclusions Our findings showed that administration of oral ibuprofen had no significant effect on the medicinal closure of PDA in full-term neonates during the second postnatal week.

Abstract
Background Combined open-heart surgery and thyroidectomy is a rare procedure. However, some difficulties will occur for cardiac surgery when thyromegaly extends into the retrosternal space. Case Details A 54-year-old woman suffering from dyspnea, chest pain and decreased left ventricular function (EF=40%) was diagnosed with coronary artery disease (3 vessel disease) and became candidate for coronary artery bypass grafting (CABG). Also, she had multinodular goiter with normal thyroid function test. After midsternotomy, a huge goiter was seen in the upper mediastinum. Because the mass had covered the ascending aorta and involved the posterior aspect of the innominate vein making access to aorta impossible, thyroidectomy was performed at first followed by CABG. Post-operation course was satisfactory. Fourteen months later, the patient was euthyroid and in NYHA class 1. Conclusion The evidence of the case showed that combined CABG and thyroidectomy can be performed safely.

Abstract
Background: The infants with congenital cardiovascular diseases are faced with too much problems in the case of their ongoing life. Mothers’ stress investigation would be important because can receive the stress from his parents. The aim of the following study was determined anxiety in mothers of children undergoing cardiac surgery. Materials and Methods: The present study was conducted by an analytical study on 69 infants’ mothers who were operated due to their cardiovascular abnormalities in Yazd Afshar Hospital (2012). In this study, some demographic information and influential factors were recorded germane to mothers’ stress, including residential location, history of infant hospitalization or congenital disease as well as some questions in the case of stimuli of the hospital environment, family support, economic situation and the mothers’ awareness of their stress. Results: There are statistically significant differences between mothers’ stress and their age (P = 0.03) and infants’ age (P < 0.0001). There are not statically significant differences between mothers’ stress score mean and their educational level (P = 0.75), the infants’ hospitalization history (P = 0.57), the history of congenital of disease in family (P = 0.24) and the family support in infant care (P = 0.08). Conclusion: Those mothers who asserted the stimuli of the hospital environment, infant and its mother support, economic situation and the mothers’ awareness lack of disease and infant status as strong stress-making stimuli enjoy a stress high mean.

Abstract
BACKGROUND Post cardiac surgery routine chest radiographs (CXRs), ordered without any clinical and laboratory indications, is a standard obligatory practice in many cardiothoracic centers. Routine CXRs incur cost, manpower, and radiation. The objective of this study is to assess early outcome in off-pump coronary artery bypass (OPCAB) patients with postoperative routine versus clinically indicated CXR protocols. MATERIALS AND METHODS This study is a randomized clinical trial conducted on 231 OPCAB candidates in Afshar Cardiac Center, Yazd, Iran. Patients were categorized into two groups. All 118 patients in group A had routine postoperative CXRs. The 113 patients in group B were selectively exposed to CXR only on clinical indications. All patients were postoperatively followed up for 30 days. Data gathered from both groups were statistically analyzed. RESULTS Routine postoperative CXRs obtained in 118 OPCAB group A candidates showed abnormal findings in 20 patients that did not require new intervention. One month follow-up of these patients showed no complications. In 113 OPCAB candidates of group B, 7 on-demand CXRs were obtained on clinical evaluation that required added intervention. In a 1-month follow-up of this group, five patients presented with symptomatic complaints. On re-examination, none needed readmission, intervention, or paraclinical evaluation. No complications were observed due to CXR elimination. CONCLUSION The study suggests that postoperative CXR selected on clinical grounds in place of routine CXR does not change early postoperative outcome of OPCAB procedure.

Abstract
Background: Coma is one of the most important complications of brain injury. Comatose patients in the intensive care units are exposed to sensory deprivation. This study aims to survey the effect of family members’ voice on level of consciousness of comatose patients hospitalized in the intensive care units. Materials and Methods: In this single-blind randomized controlled trial, 40 comatose patients with brain injury with acute subdural hematoma in intensive care units were randomly assigned into two groups. The intervention group was stimulated twice a day each time 5-15 min with a recorded MP3 from family members’ voice for 10 days. The patients’ level of consciousness was measured with Glasgow Coma Scale before and after auditory stimulations. In the control group, GCS was measured without auditory stimulation with the same time duration like intervention group. Data analysis in software SPSS version 15 and using Chi-square test, independent t-test, paired t- test and analysis of variance with repeated measures was done. Results: On the first day before the intervention, there was no a statistically significant difference between the mean of GCS in both groups (P = 0.89), but on the tenth day after the intervention, there was a significant difference (P = 0.0001) between the mean GCS in both control and intervention groups. Also, there was a significant difference between the mean daily GCS scores in two groups (P = 0.003). The findings during ten days showed the changes in the level of consciousness in the intervention group from the 4rd day of the study were more in the mean daily GCS scores than control group. Conclusion: This study indicated that family members’ voice can increase level of consciousness of comatose patients with acute subdural hematoma.

Evaluation of the effect of radiofrequency catheter ablation on autonomic function in patients with atrioventricular nodal reentrant tachycardia by head-up tilt table test. Adv Biomed Res 2015; 4:96. [PMID: 26015922 PMCID: PMC4434488 DOI: 10.4103/2277-9175.156662] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2014] [Accepted: 07/28/2014] [Indexed: 11/23/2022] Open
Abstract
Background: One of the recommended treatments for atrioventricular nodal reentrant tachycardia (AVNRT), is radiofrequency catheter ablation (RFCA). However, RFCA may affect the autonomic system. This study aims to evaluate the effect of RFCA on autonomic system in patients with PSVT by head-up tilt table (HUTT) test. Materials and Methods: In a before–after study, 22 patients with PSVT were enrolled. Data were collected with a data collection form that included two parts. Electrocardiogram (ECG), echocardiogram, 24-h Holter monitoring, HUTT test, heart rate variability (HRV) indexes, and symptoms of all patients were recorded 24 h before and 1 month after the ablation. Wilcoxon, McNemar, Mann–Whitney U, and Chi-square tests were used to analyze the data. Results: Of the total 22 patients, 31.8% were male and 68.2% were female. There were significant differences in heart palpitation (P < 0.0001) and non-specific symptoms (P = 0.031) and no significant difference in head-up tilt test results and HRV indices before and after RFCA. The results showed that there were no significant differences in specific and non-specific symptoms in patients with AVNRT with positive and negative HUTT before and after RFCA. Conclusions: The observed difference in heart palpitation and non-specific symptoms emphasized the role of AVNRT in causing these symptoms. Autonomic dysfunction is more probably an accompanying condition of AVNRT than causing symptoms. We could not find any significance in the results of HUTT after RFCA. HUTT cannot determine or predict the symptoms after RFCA.

Abstract
BACKGROUND Transcatheter closure of patent ductus arteriosus (PDA) with the Amplatzer ductal occluder (ADO) has become a standard procedure in most pediatric patients. However, experience in adults and adolescents is limited. Our experience of transcatheter closure of PDA with ADO in adolescents and adults is presented in this study. AIMS The aim of this study was to investigate long-term outcomes of transcatheter closure of PDA in adolescents and adults with ADO. MATERIALS AND METHODS In this study, 69 patients (52 females and 17 males) with PDA underwent transcatheter closure between May 2004 and October 2012. The procedure was performed under fluoroscopic guidance. Chest radiograph, electrocardiogram, transthoracic echocardiography (TTE), and clinical assessment of the patients were conducted before the procedure. Clinical and echocardiographic follow-ups were performed on day 1 of the 1st month, 6(th) month, and 12(th) month and then yearly after the procedure. RESULTS The mean and standard deviation age of the patients was 18.08 ± 7.25 years (ranging 10-38 years). The mean and standard deviation angiographic diameter of PDA was 7.78 ± 2.78 mm. The mean and standard deviation size of the implanted device was 9.3 ± 2.9. The mean and standard deviation average pulmonary artery pressure was 32.1 ± 14.2 mmHg. The mean pulmonary flow/systemic flow ratio was 2.2 ± 0.61. The devices were successfully implanted in all patients (100%). Immediately after device implantation, 47 patients had residual shunts. The residual shunts disappeared in all the patients, except for one that lingered until 24 h after the procedure. No severe complication occurred at the immediate and long-term follow-ups. CONCLUSIONS The long-term results suggested that transcatheter closure of PDA with ADO is a safe and effective treatment for adolescents and adults with PDA. Low complication rates and short hospital stays make this procedure the treatment of choice in most cardiovascular centers worldwide.

Abstract
BACKGROUND Congenital heart disease (CHD) is a major health problem and its prevalence is different around the world. The aim of study was determination of the epidemiological aspects of CHD in central and southern district of Iran. MATERIALS AND METHODS In this descriptive and analytical study, 3714 medical records were evaluated from March 21, 2001 to December 18, 2011. Medical records of inpatients from angiography and outpatients in the Heart Clinic of Afshar hospital (a referral hospital in center and south of Iran) were the source of information. Types of CHD and demographic data including age, sex and residential location are collected. The data were analyzed by SPSS (version 17) software. Chi-square and Fisher's exact tests were used to compare variables between groups. RESULTS At the study, the mean age of the patients at diagnosis time was 8.8 ± 11.6 year (at the range of one day to 76 years with median of 4 years). The percentage of females and males was 54.2 (n: 2014) and 43.8 (n: 1627), respectively. The chi-square test showed that there was significant difference in frequency of CHDs between females and males (P value < 0.0001). Ventricular septal defect (VSD) was found to be the most frequent of CHDs (27%). Patent ductus arteriosus (PDA) (16.8%), atrial septal defect (ASD) (15.8%), pulmonary stenosis (PS) (11%) and Tetralogy of Fallot (TOF) (8.9%) were more prevalent in CHDs after VSD. CONCLUSIONS The frequency of CHDs in female was more than male and VSD, PDA, ASD, PS, and TOF were most common in CHDs, respectively.

Abstract
Background: Percutaneous closure of patent ductus arteriosus (PDA) with Amplatzer duct occluder (ADO) has become increasingly popular in many cardiovascular centres. This study analysed the long-term results of percutaneous closure of PDA with ADO in a single centre. Materials and Methods: Between May 2004 and January 2013, 243 patients with median age of 2.5 years (range = 30 months to 38 years) and median weight of 10 Kg (range 4.5–80.5 Kg) underwent percutaneous closure of PDA using the ADO. The devices were implanted under fluoroscopic guidance. Patients were followed-up for any complications. Results: The mean diameter of narrow part of PDA was 6.4 ± 2.2 mm. The mean diameter of devices was 7.8 ± 2.3 mm. The devices were successfully implanted in 239 (98.3%) cases. At immediate, 1 day, 1, 6, 12 months and late follow-up, the complete occlusion rate was 33% (79 case), 97.1% (236 case), 97.5% (237 case), 98.3% (238 case), 98.3% (238 case) and 98.3% (238 case), respectively. Residual shunt remained in one case at late follow-up. The device embolisation occurred in five patients. The devices were successful retrieved in three patient and second larger devices were inserted. Two other devices were surgically retrieved and PDAs were ligated. Moderate left pulmonary artery stenosis (LPA) in one child and mild LPA stenosis in one infant were detected. Mild aortic obstruction occurred in one infant. Conclusions: Long-term follow-up of patients indicate that percutaneous closure of PDA using ADO is a safe and effective procedure. However, some complications, including device embolisation, left pulmonary stenosis and aortic obstruction may be observed in some cases.

Abstract
BACKGROUND Off-pump coronary artery bypass (OPCAB) surgery is a common technique used to control the incidence of myocardial ischemia and to increase the lifespan of patients with coronary artery disease (CAD). There is still considerable controversy about effect of OPCAB on patients' quality of life. The purpose of this study was to determine the effect of OPCAB on different aspects of the patients' quality of life. METHODS A total of 190 patients who underwent elective OPCAB surgery at Afshar Hospital in Yazd, Iran, from October 2012 through April 2013 participated in the study. Nottingham Health Profile (NHP) questionnaire was used in structured interviews before and 3 months after the OPCAB surgery. Independent samples t-test, Mann-Whitney test and analysis of variance were used for statistical analysis. RESULTS Quality of life from the aspect of pain (P = 0.014), energy (P = 0.001), emotional reaction (P < 0.001), social isolation (P = 0.002) and physical activity (P = 0.005) were significantly different, but there was no significant difference in sleep between men and women (P = 0.06). Women achieved a better quality of life 3 months after OPCAB surgery (P < 0.001). There was no significant difference in patients' quality of life in terms of their ejection fraction (P = 0.06). There was no significant difference in patients' quality of life in terms of their New York Heart Association (NYHA) functional class score (P = 0.57). Patients' quality of life scores before OPCAB surgery and 3 months after the surgery showed no significant difference after adjusting for history of myocardial infarction (P = 0.82), hyperlipoproteinemia (P = 0.38), cigarette addiction (P = 0.2), hypertension (P = 0.7) and diabetes mellitus (P = 0.15). CONCLUSION Most aspects of patients' quality of life were better after OPCAB surgery. The most obvious finding to emerge from this study was that women's quality of life was better than men's after OPCAB surgery. Since CAD is prevalent and OPCAB is one way to treat and manage this disease, patients' quality of life can be improved if they are managed appropriately after OPCAB surgery (especially for men).

Abstract
Aneurysm can develop in all arteries of the human body. Pseudoaneurysm induced by trauma is known as a rare condition in peripheral arteries. This complication is known as late sequelae of trauma. The incidence of pseudoaneurysm in upper extremities artery is less than lower extremities. Atherosclerotic aneurysms are often seen in large arteries and by aging, but pseudoaneurysm can be seen in penetrating or blunt trauma in patients of every age or every location. Delayed treatment of pseudoaneurysm leads to bleeding, venous edema at the extremities and compression on the adjacent nerve as a result of pseudoaneurysm enlargement. Early diagnosis of pseudoaneurysm is very important, because this complication can induce disabilities such as upper extremities and finger loss. Peripheral arteries pseudoaneurysm in distal locations especially in brachial artery and forearm can cause a thrombotic complication in hands and fingers.

Adenosine Preconditioning versus Ischemic Preconditioning in Patients undergoing Off-Pump Coronary Artery Bypass (OPCAB). J Tehran Heart Cent 2013; 8:127-31. [PMID: 24396361 PMCID: PMC3874371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2012] [Accepted: 10/01/2012] [Indexed: 11/03/2022] Open
Abstract
BACKGROUND During off-pump coronary artery bypass (OPCAB), the heart is subjected to ischemic and reperfusion injury. Preconditioning is a mechanism that permits the heart to tolerate myocardial ischemia. The aim of this study was to compare the effects of Adenosine preconditioning with ischemic preconditioning on the global ejection fraction (EF) in patients undergoing OPCAB. METHODS In this single-blind, randomized controlled trial, sixty patients undergoing OPCAB were allocated into three equally-numbered groups through simple randomization: Adenosine group, ischemic group, and control group. The patients in the Adenosine group received an infusion of Adenosine. In the ischemic group, ischemic preconditioning was induced by the temporary occlusion of the left anterior descending coronary artery twice for a 2-minute period, followed by 3-minute reperfusion before bypass grafting of the first coronary vessel. The control group received an intravenous infusion of 0.9% saline. Blood samples at different times were sent for the measurement of creatine kinase isoenzyme MB (CK-MB) and cardiac troponin I (cTnI). We also recorded electrocardiographic indices and clinical parameters, including postoperative use of inotropic drugs and preoperative and postoperative EF. RESULTS History of myocardial infarction, hyperlipidemia, diabetes mellitus, kidney disease, preoperative arrhythmias, and utilization of postoperative inotrope was the same between the three groups. The incidence of postoperative arrhythmias was not significant between the three groups. Also, there were no significant differences in preoperative and postoperative EF and the serum levels of enzymes (cTnI and CK-MB) between the groups. CONCLUSION Based on the findings of this study, there was no significant difference in the postoperative EF between the groups. Although the incidence of arrhythmias was higher in the ischemic preconditioning group than in the other groups, the difference between the groups did not constitute statistical significance.

Abstract
Transluminal balloon valvuloplasty is an alternative to surgical valvotomy for congenital pulmonary valve stenosis. The aim of this study was to evaluate the long term results (to 13.5 years) of balloon pulmonary valvuloplasty. From June 1998 to January 2012, percutaneous balloon pulmonary valvuloplasty for congenital pulmonary valve stenosis was performed in 98 patients (50 males, 48 females, with a median age of 6.75 years) underwent balloon valvuloplasty of pulmonary valve stenosis. Follow-up was performed based on the Doppler echocardiographic data and clinical findings. Forty three of ninety eight patients were 10 years of age or older. The mean peak to peak pressure gradient across pulmonary valve before and immediately after balloon pulmonary valvuloplasty (BPV) was 88.7±36.4 mmHg and 21.8±15.9 mmHg (P<0.001) respectively. Doppler pressure gradient across pulmonary valve before BPV, at 3 month (short term), at 1 year (intermediate term) and long-term follow-up were 93.2±41.3 mmHg, 18.7±15.8 mmHg (P<0.001), 15.8±13.1 mmHg (P<0.001) and 13.6±7.4 mmHg (P<0.017) respectively. Mild pulmonary regurgitation (PR) was observed in 55 (57%) patients immediately after BPV and 30 (31%) patients at late follow up. Rupture of the right ventricular outflow tract was the major complication in two patients with fatal event. Short, intermediate and long-term results of BPV for typical valvular pulmonary stenosis are excellent. Therefore, it can be considered as treatment of choice for patients with typical valvular pulmonary stenosis.

Abstract
QT dispersion is an indicator of lack of ventricular repolarization homogeneity and an independent predictor for ventricular arrhythmia and sudden cardiac death. In this study, we evaluated the effect of inpatient cardiac rehabilitation on QT dispersion in patients admitted to Afshar hospital CCU with diagnosis of acute myocardial infarction (AMI), including ST elevation or non-ST elevation MI. Sixty patients with diagnosis of AMI were randomly divided into two 30-subject groups. The subjects in the first group were undergone inpatient cardiac rehabilitation, and the subjects in the control group received only conventional treatments. QT interval dispersion was measured in two occasions: once in the first day of admission and once before discharge from hospital. In this study there was a significant reduction in QT dispersion in patients undergoing inpatient cardiac rehabilitation (48.4 vs. 42.4 ms, P<0.001), but in the control group, QT dispersion was not significantly reduced (49.2 vs. 46.2 ms, P>0.05). The reduction was not significantly different regarding gender. The effectiveness of the rehabilitation on the reduction of QT dispersion was not affected by such variables as age, gender, hypertension, positive family history, hyperlipidemia, type of AMI (with ST-elevation or non-ST-elevation) and left ventricular ejection fraction. Diabetes caused a resistance to the beneficial effects of inpatient cardiac rehabilitation, so as non-diabetic patients showed more reduction in QT dispersion in response to inpatient cardiac rehabilitation comparing non-diabetic patients and the difference was statistically significant.

Abstract
One of the most common complications of operation and anesthesia is shivering. The purpose of this study was to compare the effectiveness of Ondanseton and Meperedine in preventing shivering after off-pump coronary artery bypass graft (OPCAB). In this double-blind randomized clinical trial, the sample consisted of 90 patients, who were candidates of CABG under general anesthesia. These patients were assigned to three groups, each containing 30 subjects: meperedine group (A), ondansetron group (B) and control group (C). Group (A) received 0.4 mg/Kg/IV of meperedine, group (B) received 8mg/IV of ondansetron and group (C) received Normal Saline. All these drugs were injected 15 minutes before the end of surgery. After the end of surgery, the intubated patients were transferred to the ICU and their body temperature was assessed through eardrum by a specialist who was blind to the research. The incidence of shivering in groups A, B, and C was 46.48%, 31.18%, and 60.83%, respectively (P=<0.01). The incidence of shivering was 64.4% in males and 35.6% in females (P=0.222). Also, the amount of incidence of shivering up to 3 hours after surgery was 75.87 % (P=0.064). Bradycardia was 3.3% in group (A) and 0.0 % in group (B). Other variables (myoclonus, seizure and rash) showed no statistically significant difference (P=0.353). According to the findings, it was demonstrated that ondansetron is more effective in preventing shivering after Off-pump CABG than meperedine.
