Objectives: The present study aimed to evaluate the effect of 4-week HIIT on change in expression levels of ryanodine receptor calcium channel (RyR2) and ATPase calcium pump (SERCA2a) in diabetic rats. Materials and Methods: This study was conducted on 24 Wistar rats with average weight of 245 ± 10 g. The rats were randomly divided into a sedentary diabetic group and a trained diabetic group. Training was started two weeks after diabetes induction by Streptozotocin (STZ) injection. The training program consisted of 4 weeks running on a treadmill and was considered to be intense for the two groups’ diabetic rats. After all, the animals’ characteristics and myocardial gene expression were compared using independent t-test. Results: Measurement of gene expression by Real Time-PCR revealed that cardiac mRNA expression of RyR2 was enhanced in the HIIT group. The results also revealed a significant (P = 0.03) difference between the hearts of the sedentary controls and the trained group regarding RyR2 levels. However, no significant difference was observed between the two groups with respect to SERCA2a levels (P = 0.14). Conclusions: The study results showed that treatment with HIIT could prevent and/or minimize the loss in expression of RyR2 and SERCA2a.","PeriodicalId":43653,"journal":{"name":"International Cardiovascular Research Journal","volume":"10 1","pages":"1-5"},"PeriodicalIF":0.2,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68174955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: The present study aimed to evaluate the effect of Vitamin D deficiency treatment on the occurrence of coronary post-Percutaneous Intervention (PCI) restenosis and Major Adverse Cardiac Events (MACE). Patients and Methods: This randomized semi-experimental non-controlled study was conducted on patients with coronary artery disease who were candidate for PCI and had referred to Baqiyatallah Hospital in a 2-month period. The patients with normal Vitamin D levels were allocated to the normal group and others were randomly assigned to treatment and non-treatment groups. All the patients were followed for 9 months. Vitamin D was measured again at the end of the 9th month and the patients were reassigned to normal and mild, moderate, and severe deficiency groups with respect to Holick classification. Results: This study was performed on 150 subjects with the mean age of 62.46 ± 10.80 years and male/female ratio of 94/56. The results showed no significant difference among the three groups regarding age, gender, diabetes, number of cardiovascular risk factors, and other underlying risk factors for restenosis. However, a significant difference was found between the patients with normal and abnormal vitamin D levels regarding the number of stenotic vessels and number of PCIs (both P 0.05). At the end of the study, 32 (55.1%) out of the 58 patients (55.1%) who were deficient reached normal vitamin D levels by consuming supplements, but 7 (12%) reached normal values without using supplements (P < 0.001). Conclusions: Treatment of vitamin D deficiency could reduce restenosis of PCI. However, this protocol is efficient for patients with moderate to severe deficiency and should be changed.","PeriodicalId":43653,"journal":{"name":"International Cardiovascular Research Journal","volume":"10 1","pages":"12-16"},"PeriodicalIF":0.2,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68175223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Depression is also associated with worse outcomes among patients with heart disease. Fewer studies have shown whether or not baseline depressive symptoms predict subsequent heart disease in general population. Objectives: This study aimed to investigate whether depressive symptoms at baseline predict risk of developing heart disease during the next 20 years in the United States. Patients and Methods: The data were extracted from the Health and Retirement Study (HRS), 1992 - 2012. The study was conducted on 8,375 individuals who were older than 50 years at entry, did not have heart disease at baseline, and had data on heart disease over the next 20 years. High depressive symptoms (modified Center for Epidemiologic Studies Depression Scale [CES-D]) were considered as the independent variable. Self-reported data on physician diagnosis of heart disease were measured on a biannual basis. Baseline demographic data (i.e., age and gender), socioeconomic status (i.e., race, marital status, and education level), health behaviors (i.e., drinking, smoking, and exercise), and body mass index were controlled. Cox proportional hazard model was used for data analysis. Results: Cox proportional hazard model revealed a link between high depressive symptoms at baseline and time to developing heart disease (Hazard ratio = 1.439, 95% CI = 1.253 1.652), suggesting that individuals with high depressive symptoms at baseline developed heart disease sooner than others. The association between baseline depressive symptoms and risk of heart disease was significant after controlling for all the covariates. Conclusions: Individuals with depressive symptomatology are at higher risk of development of heart disease over time. Thus, individuals with depressed mood may need more rigorous evaluation for heart disease.","PeriodicalId":43653,"journal":{"name":"International Cardiovascular Research Journal","volume":"10 1","pages":"29-34"},"PeriodicalIF":0.2,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68175286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also considered to be a valid technique to evaluate the patients with Acute Coronary Syndrome (ACS). Objectives: The present study aimed to evaluate the capability of STE as a trustable technique to indicate ischemic parts of the heart and compare the results to the information raised from angiography. Then, decision was made about capability of STE as a valid and reliable criterion for determining the indication of performing angiography. Patients and Methods: This case-control study was conducted on 37 patients between 30 and 70 years old with clinical diagnosis of ACS and clinical indications of coronary angiography who had referred to Faghihi hospital. Also, 46 healthy volunteers were selected as the control group. STE was performed for all the participants and angiography was done for the patients. Results: In 20 cases (55.6%), the results of echocardiography completely matched with those of angiography. In 10 cases (27.8%), echocardiography and angiography results were partially matched. According to the results, echocardiography showed involvement of both territories, while angiography revealed involvement of one territory or viceversa.

Objectives: This study aimed to evaluate the prognostic value of circulating OSN for cumulative survival and hospitalization in patients with ischemic Chronic Heart Failure (CHF). Patients and Methods: This open cohort prospective study was conducted on 154 patients with ischemic symptomatic moderate-to-severe CHF at discharge from hospital. The observation period was up to 3 years (156 weeks). Blood samples for biomarker measurements were collected at baseline. ELISA method was used for measurement of OSN circulating level. Then, Receiver Operating Characteristic (ROC) curve analysis was carried out to identify the optimal cut-off points of the OSN concentration with predicted values. Odds ratios were also calculated for all the independent predictors of patients’ survival. Kaplan-Meier survival curves were also structured for both cohorts with low and high OSN levels. Results: During a median follow-up of 2.18 years, 21 participants died and 106 subjects were hospitalized repetitively. The median of circulating OSN levels were 670.96 ng/mL (95% Confidence Interval [CI] = 636.53 - 705.35 ng/mL) and 907.84 ng/mL (95% CI = 878.02 - 937.60 ng/mL) in the survived and dead patients cohorts, respectively. Besides, ROC curve analysis showed that optimal cut-off point of OSN for cumulative survival function was 845.15 ng/mL. The results also revealed significant divergence of KaplanMeier survival curves in the patients with high (> 845.15 ng/mL) and low (< 845.15 ng/ mL) concentrations of OSN. Conclusions: Increased circulating OSN levels were associated with increased 3-year CHF-related death, all-cause mortality, and risk of recurrent hospitalization due to CHF.","PeriodicalId":43653,"journal":{"name":"International Cardiovascular Research Journal","volume":"9 1","pages":"203-209"},"PeriodicalIF":0.2,"publicationDate":"2015-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68175857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results: The results showed significant correlations between age and waist circumference, Fasting Blood Sugar (FBS), Systolic Blood Pressure (SBP), and Diastolic Blood Pressure (DBP). Moreover, statistically significant relationships were found between waist circumference and TG, SBP, DBP, and BMI. Significant correlations were also observed between FBS and TG, SBP, and DBP. Besides, there were strong correlations between TG and HDL-c, SBP, DBP, and BMI. Moreover, BMI, SBP, and DBP were significantly correlated. In addition, serum HDL-c was negatively associated with most of the variables. The prevalence of pre-diabetes, pre-hypertension, and hypertriglyceridemia was higher among males. On the other hand, the prevalence of hypertension, diabetes, high waist circumference, and MetS was significantly higher among the female participants.
