A cross-sectional study was conducted on type II diabetic patients during 1991-1996 in Isfahan. By systemic sampling, 715 patients were enrolled. Variables studied, include: age, gender, duration of diabetes, body mass index (BMI), literacy, smoking habits, hypertension, lipid profiles, fasting blood glucose (FBS), retinopathy, ischaemic heart disease (IHD), proteinuria and type of treatment of diabetes. Prevalence of IHD in males (37.4%) was more than females (32.6%). Logistic regression analysis revealed a direct association between IHD prevalence with age, BMI, hypertension, proteinuria, diabetic retinopathy and type of treatment. Conclusions: 1) The factors mentiond are good predictors of IHD, but genetic influences may also contribute to the risk of IHD. 2) As obesity and BMI are prone to medical manipulation, control of these risk factors may decrease prevalence of IHD.

Background: The relationship between coping styles and psychological adaptation during the recovery process was investigated in a sample of coronary heart disease (CHD) patients.
Methods: One hundred and fifty patients from Shahid Rajaee Heart Center, Tehran, Iran, were included in this study at intake and forty five patients (27 men, 18 women) participated in the follow-up study. All participants were asked to complete the Tehran Coping Styles Scale (TCSS) and Mental Health Inventory (MHI). The Recovery Process Questionnaire (RPQ) was completed using each patient's medical file and clinical examinations by cardiologists. Styles of coping with stress were categorized as problem-focused, positive emotional-focused and negative emotional-focused. Psychological adaptation included psychological well-being and psychological distress.
Results: Objective recovery status showed no significant correlation with either coping styles or psychological adaptation. Perceived recovery revealed a significant positive association with negative emotional-focused coping (p<0.05), but no significant correlation with other coping and psychological adaptation variables. Perceived recovery revealed a significant negative association with psychological distress (p<0.05), but showed no significant correlation with psychological well-being.
Conclusions: Perceived recovery in CHD patients is positively influenced by negative emotional-focused coping styles. Results and implications are discussed specifically in terms of the possible reasons for the positive relationship between perceived recovery and negative emotional-focused coping.

Background: Although metabolic syndrome (METs) is receiving attention from physicians, data on the syndrome's association with coronary heart disease (CHD) in the Iranian population are limited. This study was designed to determine the association of different definitions of METs and its components with CHD.
Methods: Logistic regression analysis was used to analyze data from 5981 subjects aged ≥30 years. METs definitions by the International Diabetes Federation (IDF), the Adult Treatment Panel (ATP III) and the WHO for CHD were used in three models: model 1 an age adjusted model, model 2 adjusted for age, smoking status, premature history of CHD and LDL-cholesterol and model 3 adjusted for the mentioned variables plus the METs components.
Results: METs as delineated by all three definitions was associated with CHD in models 1 and 2. In model 2, METs was most closely associated with CHD in men, as defined by the WHO [2.3 (1.8-3)] and in women by the ATP III definition [1.6 (1.3-2)]. In model 3, METs lost its association with CHD. However, in men high fasting plasma glucose and high blood pressure plus obesity (by the WHO definition) and in women high blood pressure plus high waist circumference (by the ATP III definition), obesity and glucose domain (by the WHO definition) remained associated with CHD.
Conclusions: In Iranian men and women, all three definitions of METs were associated with CHD when considering the conventional risk factors. After further adjustments for the components of METs, none of these definitions showed an association with CHD and only high blood pressure correlated with CHD in both sexes for all definitions.

Background: Balloon atrial septostomy is an emergent procedure in pediatric cardiology. Nowadays, most patients in need of the procedure have acceptable outcomes after surgical repair. Thus, it is important to perform this procedure as safe as possible. By performing early arterial switch operation and prostaglandin infusion, the rate of balloon atrial septostomy has markedly decreased. However, not all centers performing early arterial switch repairs have abandoned atrial septostomy, even in patients who respond favorably to prostaglandin infusion.
Case presentation: In total, eight 1- to 15-day old term neonates admitted in Shahid Rajaee Heart Center in Tehran, Iran from October 2009 to February 2011, with congenital heart diseases were scheduled for balloon atrial septostomy. In six cases the procedure was done exclusively under echocardiographic guidance and in two cases with the help of fluoroscopy. Success was defined as the creation of an atrial septal defect with a diameter equal to or more than 5 mm and ample mobility of its margins.
Results: Male sex was predominant (87%) and the mean age of the neonates was six days. The diagnosis in all cases was simple transposition of great arteries. The procedure was successful in all patients with any cardiovascular complication.
Conclusion: Balloon atrial septostomy is an emergent procedure that can be done safely and effectively under echocardiographic guidance. According to the feasibility of this technique it could be performed fast, safe and effective at bedside, avoiding patient transportation to hemodynamic laboratory or referral center.

Background: Androgenetic alopecia (AGA) is the most common type of progressive balding that appears with early loss of hair, chiefly from the vertex. There has been significant relationship between AGA with coronary artery disease and related risk factors, such as hypertension in some studies. The aim of this study is to investigate the association between androgenetic alopecia with hyperlipidemia.
Methods: This cross-sectional study was performed on 112 patients with vertex type AGA (in male grade 3 or higher Hamilton- Norwood scale, and in female grade 2 or higher Ludwig scale) (study group) and 115 persons age and sex matched, with normal hair status (Normal group). None of participants had diabetes mellitus, hypothyroidism, liver disease, kidney disease and none of them had history of smoking and using drugs with effect on serum lipids. They were 20-35 years old and their body mass index were 20-30. Blood samples were obtained following 12 hours fasting status and serum levels of triglyceride (TG), cholesterol, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) were determined using standard laboratory methods. Total cholesterol greater than 240 or TG greater than 200 or LDL greater than 160 or HDL less than 40 in men or HDL less than 50 in women were considered hyperlipidemia.
Results: In androgenetic alopecia group 46.4% and 47% of normal group were female. Mean (±SE) of total cholesterol (172.4±3.1, 148.8±3.1, P< 0.001), TG (133.6±5.5, 88.3±4.3, P< 0.001), LDL (96.4±2.9, 84.9±2.7, P= 0.004) and HDL (54.9±2.0, 45.5±0.9, P< 0.001) in AGA patients were higher than normal group. %46.4 of patients and %52.2 of controls had hyperlipidemia. Relationship between AGA with hyperlipidemia was not significant (P> 0.05).
Conclusion: The findings showed that there is no relationship between AGA and hyperlipidemia. Regarding to high levels of total cholesterol, LDL and triglyceride in AGA patients, it seems that, AGA increases risk of coronary heart disease. To determine a definite association between AGA and hyperlipidemia more studies are recommended.

Background: Cardiovascular complications have very high incidence and are the main cause of mortality in human. Although the cardiovascular risk factors among apparently healthy subjects have been studied, these factors among patients who have undergone coronary artery bypass graft surgery have not evaluated clearly. Methods: The present study is a descriptive, cross-sectional survey on 1592 patients which suffered coronary artery bypass surgery (CABG) from May 2009 to May 2013 in Baqiyatallah Hospital, Tehran. Before surgery, all patients were carefully assessed and typical and atypical cardiovascular risk factors were determined and the desired data were collected. Results: More than 70.8% of subjects were men and 29.2% were women. Average age of all patients was 60.39±7.5 years and the mean weight was 73.91±6.3 kg. Typical risk factors including: smoking, plasma cholesterol level, hypertension, diabetes mellitus and family history of cardiac problems, were common in these patients. Forty seven percent of patients had diabetes mellitus, 79.4% had hypercholesterolemia, 34.3% had a smoking history, 64.5% had hypertension and 44.2% of patients had a family history of cardiovascular disease. Among atypical risk factors, various types of angina (chest pain) had high prevalence (88.8% of all). Also, mean body mass index (BMI) were higher than normal (27.46±2.1) which showed the incidence of obesity among these patients. But, other atypical risk factors did not have high incidence. Conclusion: We demonstrated that typical and well known risk factors have also high prevalence in CABG patients. Our results indicates that we can recognize high risk persons with continuous and accurate screening as a safe and inexpensive preventive tool. This can be done in both apparently healthy subjects and in cardiovascular patients. We can prevent the occurrence of severe degrees of atherosclerosis and also CABG. So the cost and performing surgeries will be decreased.

Methods: Eligible subjects in this prospective descriptive study comprised all patients with TOF presenting to Shahid Modarres Hospital in Tehran from March 2012 to March 2015 and diagnosed as the candidates for surgery. After determining the need for surgery and the therapeutic method required, the mitral valve size and Z-scores were calculated. We analyzed sex, age, body surface area (BSA), mitral size (in 2-chamber and 4-chamber view), mitral Z-score, other cardiac anomalies, number of surgery and previous surgery.
Results: Of a total of 80 patients included in the study over 3 years, 29 (36.3%) were male and 51 (63.8%) were female. The mean age of the patients was 7.15±3.37 years and their mitral size was found to be 10-27 mm (16.2±5.99 mm) using echocardiography. Z-scores of the mitral valve were also obtained as -3.09±2.11, ranging between -7.1 SD and +1.3 SD. 58 (72.5%) patients have only TOF and 22 (27.5%) with other cardiac anomalies. 45 patients were for first time underwent surgery and 22 patients for second time, 12 patients for three time and 1 for forth. Of a total of 35 patients had previous surgery, the most common were shunt 15 (42.9%) and then tetralogy of Fallot total correction (TFTC) in 12 (34.3%). Of a total of 80 patients, 59 (73.8%) underwent TFTC, 17 (21.3%) under pulmonary valve replacement and 4 (5%) shunt.
Conclusion: Z-scores of the mitral valve were found to be significantly below the normal value, (i.e. 0±2 SD), in the study patients, suggesting the risk of hypoplastic left heart syndrome in Iranian patients with TOF, nevertheless, the type of TOF examined in these patients might have been different from those observed in other races and regions.
Volume 77, Issue 7 (10-2019)
Methods: This study was conducted as a retrospective study by evaluating the records of all syndromic patients undergoing cardiac surgery at Children’s Medical Center of Excellence, Tehran University of Medical Sciences, Tehran, Iran, from March 2011 to March 2017. Age, weight, height, weight-for-age z-score (WAZ), weight-for-height z-score (WHZ), height-for-age z-score (HAZ), mortality and hospitalization rate in an intensive care unit (ICU) were recorded in these patients. The z-scores more than -1 were considered as normal, between -1 and -2 as mild malnutrition, between -2 and -3 as moderate malnutrition and below -3 as severe malnutrition.
Results: 35 (51.5%) patients were female and 33 (48.5%) were male. The mean age, weight, and height of these children were 26.9±24.9 months, 9.1±4.95 kg, and 79.55±17.95 cm, respectively. The mean of WHZ, WAZ, and HAZ in these children was -2.18+1.65, -1.95+2.25 and -1.22+3.11, respectively. Based on the values of WAZ, WHZ, and HAZ, 85.3%, 77.9% and 75% of patients have malnutrition (mild to severe forms, z-score less than -1). The most common cardiac defect was ventricular septal defect (VSD) accompanied by pulmonary arterial hypertension.
Conclusion: Considering the high prevalence of impaired nutritional status in these children and considering the effect of preoperative malnutrition on surgical outcomes, including mortality, assessing the nutritional status is much important. The adequate nutritional support in these patients leads to a reduction of the mortality, postoperative complications and morbidities.
Volume 77, Issue 9 (12-2019)
Methods: In this cross-sectional study, two hundred and fifty pediatric cardiology consultations conducted in Shahid Beheshti Hospital in the year 2012 were reviewed. Information such as the cause of consulting, delivery type, age of parents, relative couples, family history of congenital heart disease, maternal medications, maternal background diseases, the final diagnosis, and prognosis follow-up of the patients were recorded in a designed questionnaire. Finally, the data were entered into the SPSS software, version 16 (IBM SPSS, Armonk, NY, USA) and analyzed using descriptive statistics and chi-square test. P-value of less than 0.05 was considered significant.
Results: The mean age of the consulted neonates was 4.845±5.14 days with a gestational age of 33.933±3.65 weeks. Male sex and cesarean section were the most frequent. Fifty-six percent of consulted infants were male. The present study revealed that prematurity (76%), murmurs (30.8%), respiratory distress syndrome (14.4%) and cyanosis (13.2%) were the most common causes of the cardiac consultation seeking among infants. Seventy-six percent of infants were consulted due to prematurity. Eighty-four percent of infants had a normal conditions. Septal defects (ventricular or atrial septal defect) and patent ductus arteriosus were the most common disease diagnosed with the prevalence of 27.5 and 17.5%, respectively. There was a significant relationship between preterm labor and congenital heart disease (P<0.001). Additionally, prematurity associated with respiratory distress syndrome and using assisted reproductive techniques.
Conclusion: The higher prevalence of congenital heart disease in the present study, compared with other studies, reflects the fact that cardiology consultation based on clinical suspicion leads to the more identification of congenital heart disease that means the right referral of newborns for consultation was accompanied with a higher incidence of heart failure.

Methods: This randomized clinical trial study was conducted on 56 non-diabetic smokers with a history of percutaneous coronary intervention or coronary artery bypass graft surgery in Imam Khomeini Hospital from May to August 2015. Based on cardiac rehabilitation, patients were divided into intervention and control groups. Before rehabilitation, fasting blood sugar (FBS), lipid profile (LDL, HDL, triglyceride, and total cholesterol), and Ankle-Brachial Index (ABI) were measured for endothelial function. Besides, METs were measured based on the Duke activity status index. After 24 rehabilitation sessions (3 sessions of 1 hour each week for 2 months), all values were checked again and compared with the initial values.
|
Results: The mean age of the subjects in the cardiac rehabilitation and control groups were 61.18 and 52.32, respectively. Before the intervention, there were no significant differences between the two groups in terms of the ABI variables, BMI, systolic and diastolic blood pressure, LDL, triglyceride, total cholesterol and FBS; only HDL and METs showed significant differences. After exercise-based cardiac rehabilitation, the mean rate of ABI changes was +0.078 on the right side of the body and +0.084 on the left side of the body. In the control group, these values were 0.002 and 0.003, respectively (P=0.001). The amount of changes in increasing METs as well as decreasing body mass index (BMI), and systolic and diastolic blood pressure in the rehabilitation group were statistically significant compared to the control group. In addition, there were no significant differences in terms of FBS and lipid profiles either (P>0.05).
Conclusion: Two months of cardiac rehabilitation with regular exercise was associated with improved ABI as an indicator of endothelial function and prognosis of cardiovascular disease, as well as improved cardiac functional capacity among smoker patients. |

Methods: In this cross-sectional-analytical study, 163 patients with the possibility of ischemic heart disease from various clinics and medical centers referred to Imam Khomeini Hospital in Urmia for nuclear heart scanning from April to July 1400, were assessed by the DASS-21 questionnaire in terms of depression, anxiety, and stress scores. Finally, the data obtained from the DASS-21 questionnaire, nuclear scan, and demographic characteristics were analyzed with SPSS20 software.
|
Results: According to the results, the mean age of the patients was 54.78±11.54 years, 73% of whom were women. The prevalence of depression, anxiety, and stress was high (72.4, 80.3, and 59.5%, respectively). Although the prevalence of depression, anxiety, and stress in patients with a negative report of ischemia was higher and evaluated as 73.2, 78.7, and 58.3% respectively, there was not a significant difference with the subjects whose heart scan results were positive (P>0.05). Moreover, a weak positive correlation was observed between the severity of depression, anxiety, and stress with the severity of cardiac ischemia in study patients.
Conclusion: The results of this study revealed that the depressive, anxiety, and stress symptoms in patients before a cardiac nuclear scan are often moderate to mild. Likewise, among the different demographic characteristics of patients, only gender played an important role in these disorders. Regardless of the negative nuclear scan results in most patients (77.9%), the prevalence of these psychological symptoms in the studied patients was high. Therefore, considering the possibility of psychological disorders with clinical manifestations mimicking cardiovascular can prevent additional costs for diagnostic and therapeutic procedures in these patients. |

Methods: This was a prospective cohort study from March 2022 to March 2023 in Mazandaran heart center. The study population was patients who underwent angioplasty through the femoral artery. If the ACT is less than 150-180, sheet removal was done by applying pressure with the hand on the proximal puncture site for 15-20 minutes and ensuring sufficient hemostasis. Then, the ultrasound of the puncture site was performed before pulling the sheet/one hour and six hours after pulling the sheet, and after collecting the data, the data were analyzed to study the effect of BMI, BP, sex, hematocrit, hemoglobin, age, time of sheet removal, anticoagulant agent, etc. on prevalence of hematoma and it size.
|
Results: 200 patients were examined, of which 44(22%) had hematoma. Women had hematoma more than men (P<0.05). BMI and blood pressure in patients with hematoma decreased and increased, respectively (P<0.05). Older age, female gender, lower hematocrit, and longer duration of sheet retention were effective factors in increasing hematoma size (P<0.05). In the logistic regression model, with increasing BMI, the chance of hematoma occurrence decreased (P=0.029, OR=0.831).
Conclusion: Controlling blood pressure and preventing of decreasing the hematocrit, reduces the incidence of hematoma in patients after angiography. Also, preventing hematocrit drop and removal of sheet at the appropriate time, can prevent of increasing in size of hematoma. There is some difference between nursing report and sonography finding. Nursing report overestimated the hematoma size. |
