Abnormal ECG patterns in chronic post-war PTSD patients: a pilot study.

BACKGROUND: Posttraumatic stress disorder (PTSD) is a psychiatric syndrome associated with high levels of sympathetic activation of the autonomic nervous system. Individuals diagnosed with PTSD have a high propensity for electrocardiogram (ECG) abnormalities, atrioventricular conductive defects, and cerebrovascular incidents. PURPOSE: The aim of this study was to investigate ECG abnormalities in post-war PTSD patients. METHOD: This pilot study compared patients diagnosed with chronic post-war PTSD (n = 30) to patients diagnosed with major depressive disorder (MDD; n = 24) and healthy controls (n = 20). Following the completion of the Structured Clinical Interview for the DSM (SCID), participants were assessed with a standard 12-lead ECG. RESULTS: ECG abnormalities were observed in 66.7% of PTSD patients and 70.8% of MDD patients. In contrast, only 28.6% of the healthy control group showed ECG abnormalities. Multivariate logistic regression was used to adjust for participants' sex, smoking rate, education level, disease duration, and marital status. The results indicated that PTSD and MDD patients were more likely to have ECG abnormalities than the normal population (odds ratio for PTSD = 12.7, 95% confidence interval 1.9-83.9; and odds ratio for MDD = 14.9, 95% confidence interval 1.3-170.5). CONCLUSION: PTSD and MDD patients showed elevated rates of ECG abnormalities compared to healthy controls. These findings have important implications for the medical treatment of PTSD and MDD given that both of these patient groups appear to be at increased risk of cardiovascular disorder.

Validity of Self-reported Hypertension and Factors Related to Discordance Between Self-reported and Objectively Measured Hypertension: Evidence From a Cohort Study in Iran.

OBJECTIVES: Self-reporting can be used to determine the incidence and prevalence of hypertension (HTN). The present study was conducted to determine the validity of self-reported HTN and to identify factors affecting discordance between self-reported and objectively measured HTN in participants in the Ravansar Non-Communicable Diseases (RaNCD) cohort. METHODS: The RaNCD cohort included permanent residents of Ravansar, Iran aged 35-65 years. Self-reported data were collected before clinical examinations were conducted by well-trained staff members. The gold standard for HTN was anti-hypertensive medication use and blood pressure measurements. The sensitivity, specificity, positive and negative predictive values, and overall accuracy of self-reporting were calculated. Univariate and multivariate logistic regression were used to examine the discordance between self-reported HTN and the gold standard. RESULTS: Of the 10 065 participants in the RaNCD, 4755 (47.4%) were male. The prevalence of HTN was 16.8% based on self-reporting and 15.7% based on medical history and HTN measurements. Of the participants with HTN, 297 (18.8%) had no knowledge of their disease, and 313 (19.9%) had not properly controlled their HTN despite receiving treatment. The sensitivity, specificity, and kappa for self-reported HTN were 75.5%, 96.4%, and 73.4%, respectively. False positives became more likely with age, body mass index (BMI), low socioeconomic status, and female sex, whereas false negatives became more likely with age, BMI, high socioeconomic status, smoking, and urban residency. CONCLUSIONS: The sensitivity and specificity of self-reported HTN were acceptable, suggesting that this method can be used for public health initiatives in the absence of countrywide HTN control and detection programs.

Antihyperlipidemic Effect of Syrian Mesquite (Prosopis farcta) Root in High Cholesterol Diet-Fed Rabbits.

Prosopis farcta root has been proposed as an efficacious natural drug for cardiovascular disorders in traditional medicine. The present study evaluates the efficacy of aqueous extract of Prosopis farcta root on experimental atherosclerosis development in rabbits with high cholesterol diet-induced hypercholesterolemia. Serum lipid parameters were significantly increased in the high cholesterol diet groups in comparison with the normal control group (P < .050). Histopathological findings revealed that atheromatous plaques were formed in both thoracic and abdominal aorta of hypercholestrolemic rabbits. Treatment with Prosopis farcta root significantly reduced total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein, and very low density lipoprotein levels compared to high cholesterol diet rabbits (P < .050). This finding may reflect a reduction of chest pain or the beneficial effects of this plant root extract on cardiovascular health. The present study can serve as a basis for future investigations on the other effects of this plant on cardiovascular health.

The Effective Factors for Fruit and Vegetable Consumption among Adults: A Need Assessment Study Based on Trans-Theoretical Model.

INTRODUCTION: The World Health Organization recommended consuming at least 5 servings of fruits and vegetables (FV) per day in order to reduce the risk of non-communicable diseases (NCDs). The purpose of this study is to determine the influential factors related to intake of FV among adults in Kermanshah city based on Transtheoritical Model. MATERIAL & METHODS: This is a cross-sectional study which is conducted in Kermanshah city. Participants (n=1230) are selected by multi stage sampling; 30-50 year olds people covered by health centers. In order to collect data, we used a TTM-based questionnaire. The results are analyzed using SPSS-16 and Lisrel 8, with P< 0.05 as statistically significant level. RESULTS: The mean age of the participants is 37.75 and 65% of them are women .The mean score of knowledge is 2.4; that is, 80% of men and 78% of women in this study are in poor knowledge about FV consumption. In case of fruit and vegetable consumption behavior, 50% and 61% of participants are in pre-contemplation/contemplation stage, respectively. The average number of fruit servings is 1.42 and the average number of vegetable servings is 0.99 per day. Also, ANOVA test results showed a significant correlation between constructs of TTM and stages of change so that individuals' progress through stages of change from pre-contemplation to maintenance added on the scores of self-efficiency, processes of change, and decisional balance. CONCLUSION: This study indicated that, TTM constructs such as self-efficacy, processes of change, and decisional balance are good predictors for FV consumption.

The Value of Pre- and Post-Stenting Fractional Flow Reserve for Predicting Mid-Term Stent Restenosis Following Percutaneous Coronary Intervention (PCI).

Measuring fractional flow reserve (FFR) in percutaneous coronary intervention (PCI) has predictive value for PCI outcome. We decided to examine the utility of pre- and post-stenting FFR as a predictor of 6-month stent restenosis as well as MACE (major adverse cardiac events). Pre- and post-stenting FFR values were measured for 60 PCI patients. Within 6 months after stenting, all patients were followed for assessment of cardiac MACE including myocardial infarction, unstable angina, or positive exercise test. Stent restenosis was also assessed. Cut-off values for pre- and post-stenting FFR measurements were considered respectively as 0.65 and 0.92.Stent restenosis was detected in 4 patients (6.6%). All 4 patients (100%) with restenosis had pre-stenting FFR of < 0.65, while only 26 of 56 patients without restenosis (46.4%) had pre-stenting FFR value of < 0.65 (P= 0.039). Mean pre-stenting FFR in patients with restenosis was significantly lower than in those without restenosis (0.25 ± 0.01 vs. 0.53 ± 0.03, P= 0.022). Although stent restenosis was higher in patients with post-stenting FFR of < 0.92 (2 cases, 9.5%) than in those with FFR value of ≥ 0.92 (2 cases, 5.1%), the difference was not statistically (P= 0.510). Pre-stenting FFR, the use of longer stents, and history of diabetes mellitus can predict stent restenosis, but the value of post-stenting FFR for predicting restenosis was not explicit.

Association between cholesteryl ester transfer protein TaqIB variants and risk of coronary artery disease and diabetes mellitus in the population of western Iran.

AIMS: To shed light on the previously inconsistent results about the association of cholesteryl ester transfer protein TaqIB (CETP TaqIB) variants, high-density lipoprotein cholesterol (HDL-C) levels, and the risk of coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM). METHODS: To determine the frequency of CETP TaqIB variants and to examine the possible association between CETP TaqIB polymorphism with CAD and T2DM, we studied 207 unrelated patients with CAD, 101 patients with T2DM, and 92 controls. The CETP TaqIB variants were detected by polymerase chain reaction-restriction fragment length polymorphism. RESULTS: Logistic regression analysis indicated that the B1 allele of CETP was significantly associated with increased risk of CAD (odds ratio, OR 1.65 [95% confidence interval, CI 1.2-2.3, p=0.005]) and T2DM (OR 1.7 [95% CI 1.13-2.54, p=0.005]). Adjusted logistic regression analysis for the effects of age, sex, hypertension, diabetes, and hyperlipidemia was performed; and a significant association was found between the B1 allele and risk of CAD (OR 1.9 [95% CI 1-3.6, p=0.049]) in patients with CAD. There were no associations between the CETP alleles and the levels of triglycerides, total cholesterol, low-density lipoprotein cholesterol, and HDL-C in studied groups. CONCLUSIONS: The results of the present study revealed that the CETP B1 allele is associated with increased risk of CAD and T2DM independent of plasma HDL-C level in our population.
