Abstract
Background: Despite recent improvement in coronary intervention, there are many controversies about it’s results in diabetic patients. The goal of this study is comparison of in hospital outcome of diabetics after coronary intervention with nondiabetics.
Methods: In this study 115 diabetic and 115non diabetic patients who admitted for coronary intervention in our center during 1383&84 were entered in an analytic study of Cohort type. Datas about clinical, aniographic, procedural and post procedural (24hours) characteristics were entered in each patient’s form. Independent T test,chi-square and Fisher’s exact test were used for analyzing datas.
Results: The Diabetic Patients were most often older men, and they had higher angina class, more co-risk factors and lower ejection fractions. Diabetic’s lesions were longer and more located in proximal portion of vessels. But success rate, major complication (death, revascularization, Q Wave MI and CVA), and minor complications (coronary/peripheral arteries complication, pulmonary edema, ischemic ECG) had no significant differences between two groups.
Conclusion: Diabetes mellitus does not affect short outcomes of coronary intervention as an independent factor. So intervention could be done in these patients with considering favorable outcomes.

Abstract
Background: Percutaneous Coronary Intervention (PCI) for bifurcated lesions is associated with a low rate of success and high rate of complications compared to such treatment of lesions of most other morphologies. Symptoms occurring at the time of procedure caused by PCI may require additional angiography with or without stenting through stent struts, which subsequently increases risks of restenosis and stent thrombosis. The purpose of this study was to evaluate the incidence of major side branch (>1mm) complications during PCI and their clinical, angiographic, and interventional predictors.
Methods: Of 104 consecutive patients, we evaluated 50 lesions with ostial stenosis (group 1) and 54 lesions without ostial stenosis (group 2) as a control group. Age, sex, major coronary artery disease risk factors, and left ventricular ejection fraction (LVEF), were compared between groups. Morphology, location, type of lesion, length of lesion, main and side branch diameters, interventional approach, and clinical and interventional outcomes were the main variables studied during this trial.
Results: Side Branch Compromise (SBC) occurred in 41 (39.4%) of the total number of cases: 52% in group 1 and 27.8% in group 2 (p=0.01). More than 80% of SBC occurred in main branches with stenosis (p=0.02). SBC did not correlate with clinical characteristics, bifurcation location, LVEF, or stent number. Chest pain was reported in 18% of the cases during or after PCI. Three non Q wave myocardial infarctions (MI) occurred after SBC, each with >2 mm branch diameters (p=0.02). SBC was not associated with adverse clinical outcomes.
Conclusion: The risk of MI after losing the side branch of a bifurcation lesion is not usually as high as it is after losing the main branch. Furthermore, it may not be a serious problem as one of the problems of the bifurcation lesion is the high rate of post procedural non Q wave MI associated with SBC. These findings demonstrate that side branch ostial stenosis >50%, and main branch stenosis >80% were important predictors of SBC. Protection of side branches >2mm is highly recommended during coronary intervention.

Abstract
Background: Several randomized controlled trials have demonstrated the safety and efficacy of drug eluting stents (DES) in selected groups of patients with less complicated diabetes. We conducted this study to determine how an unselected group of diabetic patients in Iran fare following DES implantation.
Methods: Data were collected on 147 consecutive diabetic patients who underwent percutaneous coronary intervention (PCI) with the implantation of at least one DES at the Tehran Heart Center from June 2003 to September 2005. Clinical follow-up was performed by timely scheduled visits at one, four and nine months following DES implantation. Nine months of follow-up was completed for 94.5% of the patients. The primary endpoint was the occurrence of major adverse cardiac events (MACE), which include cardiac death, myocardial infarction and target vessel revascularization (TVR). In-hospital complications were the secondary endpoint.
Results: A total of 158 coronary artery lesions were treated with DES in 147 diabetic patients (mean age = 56.4±8.92 years, 57.1% were men). During the nine-month follow-up, MACE occurred in 3.4% of patients, with a myocardial infarction rate of 1.4% and TVR rate of 1.4%. Considering one patient who underwent TVR due to acute stent thrombosis following angioplasty (during hospitalization) the total number of TVR reached 3 (2%). Only one patient (0.7%) died of cardiac death, which occurred after the procedure and before discharge. In-hospital complications occurred in six patients (4.1%) five patients suffered from myocardial infarction.
Conclusions: PCI with DES seems to be safe and effective in diabetic patients. However, more studies with larger study populations and longer follow-up are required to confirm this issue.

Abstract
Background: Considering the psycho-social model of diseases, the aim of this study was to evaluate the effect of psychiatric intervention on the pregnancy rate of infertile couples.
Methods: In a randomized clinical trial, 638 infertile patients referred to a university infertility clinic were evaluated. Among them, 140 couples with different levels of depression in at least one of the spouses were included in this substudy. These couples were divided randomly into two groups. The patients in the case group received 6-8 sessions of psychotherapy before starting infertility treatment and were given fluoxetine 20-60 mg per day during the same period. The control group did not receive any intervention. Three questionnaires including the Beck Depression Inventory (BDI), Holmes-Rahe stress scale and a socio-demographic questionnaire were applied for all patients. The clinical pregnancy rates of the two groups, based on sonographic detection of the gestational sac six weeks after LMP, were compared. The data were analyzed by paired-T test, T-test, χ2 and the logistic regression method.
Results: The pregnancy rate was 47.1% in the case group and 7.1% in the control group. The pregnancy rate was significantly related to the duration and cause of infertility and the level of stress in both groups (p< 0.001). The pregnancy rate was shown to be higher in couples in which the male has a secondary level of education (p< 0.001).
Conclusions: Psychiatric interventions greatly improve pregnancy rates, and it is therefore crucial to mandate psychiatric counseling in all fertility centers in order to diagnose and treat infertile patients with psychiatric disorders and help couples deal with stress.

Abstract
Background: Percutaneous coronary intervention (PCI) may been associated with high-er risk of cardiac events during this procedure. The goal of this study was to compare high dose atorvastatin therapy with low dose atorvastatin therapy 24 hours before PCI to a reduction in Peri- percutaneous coronary intervention myocardial infarction.
Methods: One hundred ninety patients with stable angina were enrolled in a randomiz-ed controlled clinical trial study. All patients received low dose atorvastatin. The patients scheduled for elective PCI were randomized to atorvastatin (80 mg/d, n=95) or placebo (n=95) within 24 hours before the procedure. Creatine kinase-MB, troponin I, and high sensitive C- reactive protein levels were measured at baseline and at 6 and 12 hours after the procedure. PCI related myocardial infarction was defined as increasing of Creatine kinase-MB or troponin I three times compared with values before procedure.
Results: Myocardial infarction was detected after coronary intervention in 4.2% of patients in the atorvastatin group and in 13.7% of those in the placebo group (P=0.022). Mean of changed levels of Creatine kinase-MB (0.7±0.5 versus 3.3±1.9 ng/mL, P<0.001), troponin I (0.1±0.2 versus 0.4±0.7 ng/mL, P=0.052) and hs-CRP (0.1±0.5 versus 1±0.9 ng/mL, P<0.001) were significantly lower in the statin than in the placebo group.
Conclusion: Pretreatment with high dose atorvastatin within 24 hours before elective percutaneous coronary intervention significantly reduces procedural myocardial infarct-tion in elective coronary intervention.

Abstract
Background: To reduce cesarean section rate, we need complex interventions to modify related behavior. We aimed to identify the effectiveness of a community-based intervention on prenatal care status, delivery and decline of cesarean section rate. Methods: A quasi-experimental study was carried out on mothers residing in Khak Sefid and Javadiyeh in Tehran from January 2011 to September 2014. Study population was 274 mothers attending in health centers for first vaccination of their neonates. Mothers' demographic data were recorded in some questionnaires. One year interventions including consultation, distribution of educational package and training courses (for mothers, fathers and their families, educational programs for midwives, obstetricians and gynecologist, residents, medical students), accomplishment of 10 steps baby-friendly principles and provision adequate personnel in labor-delivery room were implemented in community, hospitals and health centers. After intervention, 250 mothers who were attending in health centers for vaccination of 2 months aged neonates were assessed and their data were recorded in the same questionnaires. The effectiveness of intervention on cesarean section rate and cesarean tendency in before and after intervention groups were compared. P< 0.05 was considered as level of significance. Results: Of 274 mothers in "before intervention" group 193 (70.44%) and of 250 mothers in "after intervention", 169 subjects (67.6%) had cesarean section. Although a significant decline was seen in cesarean tendency in "after intervention" group (P= 0.034), no significant difference was seen between 2 groups' cesarean section rates (P= 0.48). In "after intervention" group episiotomy, induction of labor rate and maternal morbidity were significantly lower than "before intervention" group (P= 0.0001, 0.0001, 0.01). Although no significant difference was seen between two groups neonatal birth weight (P= 0.69), a significant difference was seen between two groups' gestational age (P= 0.007). Conclusion: After intervention, in spite of no decline in cesarean section rate, NVD tendency and morbidity rate were raised and improved respectively. It seems that cesarean section rate was influenced by other important factors.

Abstract
Background: Abnormal placental adhesion refers to abnormal placental implantation in which the anchoring placental villi attach to myometrium and even uterine serosa which may invade the bladder and bowels. One of the most important complications of these abnormalities is severe hemorrhage during placental removing which may even necessitate cesarean hysterectomy. Since uterine conservation is an important issue especially in young women at reproductive age, conservative management has a cardinal role to reduce bleeding during surgery. Uterine artery embolization as the first line conservative approach is reserved for women that fertility preservation is very important or whom the risk of severe bleeding during cesarean section is very high due to abnormal placental adhesion. Use of embolization in unstable patients is limited because it usually cannot be performed as rapidly as other measures. The aim of this study was to report two cases of uterine artery embolization before cesarean section in pregnant women with abnormal placental adhesions.
Case presentation: Two 35 and 37-year-old pregnant women at gestational age of 34 weeks diagnosed as placenta previa and abnormal placental adhesion (placenta percreta) who intended to preserve their fertility underwent bilateral uterine artery embolization before cesarean section in Ghaem hospital, Mashhad University of Medical Sciences, Iran at September 2016. Bleeding during surgery was significantly decreased and uterine preservation was successfully preformed without any serious complications during and after the surgery. In the next follow-ups, they had normal menstruation about two months after the cesarean section.
Conclusion: In placental adhesive disorders, uterine artery embolization at the time of cesarean section could significantly decrease bleeding during surgery, so uterine and fertility preservation could be performed in this situation.

Abstract
Background: Hypertension induces cardiac hypertrophy. Oxidative stress plays an important role in the pathogenesis of hypertension induced cardiac hypertrophy. Exercise and Quercetin (as activators of Sirtuins) reduce oxidative stress. The aim of this study was to investigate the effect of high-intensity interval training (HIIT) with Quercetin supplement on oxidative stress and level of concentric pathologic hypertrophy in patients with hypertension and coronary heart disease after angioplasty.
Methods: The present study was conducted experimentally randomized, placebo-controlled and double‑blind on 24 men with hypertension and coronary heart disease after angioplasty aged 40-60 since years May to August 2019 at the Exercise Physiology department of Sport Sciences Faculty, Shahid Rajaee Teacher Training University, Tehran, Iran. The subjects were randomly divided into two groups of HIIT+quercetin (n=12) and HIIT+placebo (n=12) and were followed during 8 weeks of high-intensity interval training (30 seconds of activity and 30 seconds of rest) and quercetin consumption (250 mgr of quercetin supplement or placebo pills daily). Echocardiography was used to investigate morphological factors such as posterior wall dimension (PWd) and left ventricular end diastolic diameter (LVEDd). Plasma total antioxidant capacity (TAC) and malondialdehyde (MDA) were measured by colorimetric method.
|
Results: The results showed that MDA and The relative wall thickness (RWT) decreased after 8 weeks in HIIT+ supplement and HIIT+placebo groups and TAC level and LVEDd increased significantly (P<0.05). PWd decreased significantly only in the exercise+supplement group (P<0.05). No significant difference between groups in any other variables was detected (P>0.05).
Conclusion: Eight weeks of high-intensity interval training alone or with quercetin by reducing oxidative stress(increasing total antioxidant capacity (TAC) and reducing malondialdehyde (MDA) reduces level of concentric pathologic hypertrophy in men with hypertension and coronary heart disease after angioplasty. So that high-intensity interval training with quercetin supplementation has relatively more effects.

Abstract
Background: In patients with ST-segment elevation myocardial infarction (STEMI), Primary percutaneous coronary intervention (PCI) is the preferred reperfusion therapy. Timely primary PCI is essential in improving the clinical outcomes of these patients. The aim of this study was to evaluate the factors affecting balloon delay in STEMI treated patients by primary PCI and its relationship with major adverse cardiac events (MACE).
Methods: This prospective observational study was conducted on 143 cases of STEMI patients, who had the inclusion criteria and were treated by primary PCI, after obtaining written consent in Imam Khomeini hospital in Ahvaz, between May 2019 to May 2020. All-time components from symptom onset to PCI treatment include symptom-to-balloon time or ischemic time, symptom-to-door time and door-to-balloon time calculated. The incidence of major adverse cardiovascular events (MACE) including decompensated heart failure (DHF), acute coronary syndrome (ACS), sudden cardiac death (SCD) and cerebrovascular accident (CVA) was evaluated during 12 months follow up after primary PCI. left ventricular ejection fraction (LVEF) changes were evaluated 3 months after primary PCI.
Results: The median symptom-to-door time was 200.5 minutes (IQR: 90-438.75 min), the median ischemic time was 406 minutes (IQR: 231-671 min), and most patients had an ischemic time ≥120 minutes (92.4%) and door-to-device time ≥90 minutes (64.3%). The most common delay for treatment was in the symptom-to-door time (76.9%) and then the decision for primary PCI to transfer to the cat lab (17.5%). Overall, 59 (41.3%) of the patients experienced MACE during 1-year of follow-up, including ACS (13.3%), DHF (22.4%), cardiac death (9.8%) and CVA (2.1%). The patients age (OR: 0.96, P=0.020), LVEF changes (OR: 1.123, P=0.005) and STEMI type (OR: 0.705; P=0.039) predicted in-hospital MACE, while the symptom-to-balloon time (P=0.607) and door-to-balloon time (P=0.347) were not associated with MACE.
Conclusion: None of the time intervals were associated with the occurrence of MACE in one-year follow-up, and most STEMI patients were admitted to the hospital with a long delay. Therefore, efforts to shorten the time of hospitalization admission can help improve the MACE in STEMI patients under primary PCI in our medical centers. |

Abstract
Background: Vascular traumas are among the important traumas, most of which lead to significant complications due to the lack of correct and timely diagnosis, considering the frequency of penetrating vascular injuries, especially in our country and Khuzestan province, as well as the complications and mortality caused by injuries. This study was designed to investigate the effect of vascular surgery intervention on patients with arterial injury of forearm trauma.
Methods: In this descriptive-analytical study, all trauma patients suspected of penetrating forearm arterial injuries in terms of age, sex, type of trauma, location of trauma, type of intervention, location of arterial repair, angiographic and clinical findings including damaged arteries, type of injury Arterial fracture or dislocation. The proximity of vascular damage and the complications of surgical interventions are investigated.
|
Results: The results of this study showed that among the penetrating trauma patients requiring surgical intervention, 90.4% were men and only 6.9% were women. The average age of the patients was 32 years. The most frequent trauma requiring surgical intervention in this study was primary repair of a stab wound in the ulnar artery and the least was due to explosive. According to the obtained results, there was a statistically significant relationship between the amount of bleeding, the days of hospitalization and the duration of the operation with the type of trauma. The most damaged artery was ulnar artery 7.50% and the most type of arterial damage was arterial cut with active bleeding (7.39%).
Conclusion: According to the results of the present study, the most damage was in the ulnar artery caused by trauma with sharp objects (knives). The incidence of complications in primary repair surgery was higher than other types of surgical interventions, and there was a statistically significant relationship between the amount of bleeding, days of hospitalization, and duration of surgery with the type of trauma.

Abstract
Background: As survival rates among breast cancer patients improve, cardiovascular disease (CVD) has emerged as a leading cause of long-term morbidity and mortality in postmenopausal survivors. This epidemiological transition from oncologic risk to cardiometabolic vulnerability reveals a critical yet underexplored dimension of survivorship care. Structured exercise training represents a promising intervention, and this narrative review-grounded in a systematic literature search investigates the effects of aerobic, resistance, and combined training modalities on cardiovascular health in postmenopausal women with breast cancer. The review synthesizes evidence across physiological mechanisms, clinical outcomes, and implementation challenges to provide a comprehensive perspective on exercise oncology in this underserved population.
Methods: A systematic search of reputable international databases including PubMed, Scopus, Web of Science, Embase, and Google Scholar as well as Persian databases SID and Magiran was conducted to identify relevant human studies, clinical trials, and randomized controlled trials published between January 2000 and April 2025. Screening, selection, and synthesis of the studies were performed in Iran between October 2024 and January 2025.
Results: Accumulating evidence supports that structured exercise especially combined aerobic and resistance training exerts substantial cardioprotective effects through multiple mechanisms, including reductions in systemic inflammation, improvements in body composition, regulation of blood pressure, enhancement of cardiorespiratory fitness, and improved left ventricular function. Combined interventions consistently outperformed single-modality programs, underscoring the importance of integrative approaches in oncologic rehabilitation. Despite this promise, persistent barriers such as limited access to trained personnel, lack of individualized protocols, and weak institutional support impede translation into routine practice. Notably, few existing reviews have bridged mechanistic, clinical, and operational domains in this population, highlighting a significant gap in the literature.
Conclusion: Exercise training is not merely an adjunct to care it is a clinically potent, physiologically grounded, and policy-relevant strategy for mitigating cardiovascular risk in postmenopausal breast cancer survivors. Given the increasing burden of CVD in this group, integrating personalized, evidence-based exercise into oncologic care pathways is both urgent and essential for advancing survivorship standards and informing future clinical guidelines.
