Predictive factors of short-term survival from acute myocardial infarction in early and late patients in Isfahan and Najafabad, Iran

Background: Cardiovascular disease (CVD) is the primary cause of mortality in the world and Iran. The aim of this study was to determine the prognostic factors of short-term survival from acute myocardial infarction (AMI) in early and late patients in the Najafabad and Isfahan County, Iran. Methods: This hospital-based cohort study was conducted using the hospital registry of 1999-2009 in Iran. All patients (n = 14426) with an AMI referred to hospitals of Isfahan and Najafabad were investigated. To determine prognostic factors of short-term (28-days) survival in early and late patients, unadjusted and adjusted hazard ratio (HR) was calculated using univariate and multivariate Cox regression. Results: The short-term (28-day) survival rate of early and late patients was 96.6 and 89.4 (P < 0.001), respectively. In 80.0 of early and 79.3 of late patients, mortality occurred during the first 7 days of disease occurrence. HR of death was higher in women in the two groups; it was 1.97 in early patients was confidence interval (CI) 95%: 1.32-2.92 and 1.35 in late patients (CI 95%: 1.19-1.53) compared to men. HR of death had a rising trend with the increasing of age in the two groups. Conclusion: Short-term survival rate was higher in early patients than in late patients. In addition, case fatality rate (CFR) of AMI in women was higher than in men. In both groups, sex, age, an atomic location of myocardial infarction based on the International Classification of Disease, Revision 10 (ICD10), cardiac enzymes, and clinical symptoms were significant predictors of survival in early and late patients following AMI. © 2016, Isfahan University of Medical Sciences(IUMS).

Trends of 28 days case fatality rate after first acute myocardial infarction in Isfahan, Iran, from 2000 to 2009

Background: The purpose of the present study was the analysis of the trends in case fatality rate of acute myocardial infarction (AMI) in Isfahan, Iran. This analysis was performed based on gender, age groups, and type of AMI according to the International Classification of Diseases, version 10, during 2000-2009. Methods: Disregarding the Multinational Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA), this cohort study considered all AMI events registered between 2000 and 2009 in 13 hospitals in Isfahan. All patients were followed for 28 days. In order to assess the case fatality rate, the Kaplan-Meier analysis, and to compare survival rate, log-rank test were used. Using the Cox regression model, 28 days case fatality hazard ratio (HR) was calculated. Results: In total, 12,900 patients with first AMI were entered into the study. Among them, 9307 (72.10) were men and 3593 (27.90) women. The mean age in all patients increased from 61.36 ± 12.19 in 2000-2001 to 62.15 ± 12.74 in 2008-2009, (P = 0.0070); in women, from 65.38 ± 10.95 to 67.15 ± 11.72 (P = 0.0200), and in men, from 59.75 ± 12.29 to 59.84 ± 12.54 (P = 0.0170),. In addition, the 28 days case fatality rate in 2000-2009 had a steady descending trend. Thus, it decreased from 11.20 in 2000-2001 to 07.90 in 2008-2009; in men, from 09.20 to 06.70, and in women, from 16.10 to 10.90. During the study, HR of case fatality rate in 2000-2001 declined; therefore, in 2002-2003, it was 0.93 95% confidence interval (CI) = 0.77-1.11, in 2004-2005, 0.88 (95% CI = 0.73-1.04), in 2006-2007, 0.67 (95% CI = 0.56- 0.82), and in 2008-2009, 0.69 (95% CI = 0.56-0.82). Conclusion: In Isfahan, a reduction was observable in the trend of case fatality rate in both genders and all age groups. Thus, there was a 29.46% reduction in case fatality rate (27.17% in men, 32.29% in women) during the study period. © 2015, Isfahan University of Medical Sciences(IUMS). All rights reserved

Stress as a risk factor for noncompliance with treatment regimens in patients with diabetes and hypertension

BACKGROUND: We have assessed the role of stress on compliance of patients with diabetes mellitus (DM) and hypertension (HTN) with taking prescribed medications and following dietary and exercise regimens. METHODS: A total of 9544 individuals more than 19 years of age were selected from three counties in central Iran. The presence of DM and HTN were asked from participants. We defined treatment adherence (compliance) based on agreement of individual�s self-report behavior with recommendations from a physician. RESULTS: Awareness about DM and HTN was 82.6 and 49.9, respectively. Multivariate analysis showed that odds ratio (OR) of high to low stress level was lower than one for both �usage of medication� and �following exercise regimen� in diabetics even after adjustment for either �age and sex� or �age, sex and education�. In hypertensive patients, OR of high to low stress level was lower than one for �usage of medication� even after adjustment for either �age and sex� or �age, sex and education� and also lower than one for �following exercise regimen� only as crude index. CONCLUSION: Cases with higher stress level had lower compliance for accepting either medication or exercise as a treatment option for their DM or HTN. © 2016, Isfahan University of Medical Sciences(IUMS).

The relationship between a plant-based diet and mental health: Evidence from a cross-sectional multicentric community trial (LIPOKAP study)

BACKGROUND: Dietary patterns emphasizing plant foods might be neuroprotective and exert health benefits on mental health. However, there is a paucity of evidence on the association between a plant-based dietary index and mental health measures. OBJECTIVE: This study sought to examine the association between plant-based dietary indices, depression and anxiety in a large multicentric sample of Iranian adults. METHODS: This cross-sectional study was performed in a sample of 2,033 participants. A validated food frequency questionnaire was used to evaluate dietary intakes of participants. Three versions of PDI including an overall PDI, a healthy PDI (hPDI), and an unhealthy PDI (uPDI) were created. The presence of anxiety and depression was examined via a validated Iranian version of the Hospital Anxiety and Depression Scale (HADS). RESULTS: PDI and hPDI were not associated to depression and anxiety after adjustment for potential covariates (age, sex, energy, marital status, physical activity level and smoking). However, in the crude model, the highest consumption of uPDI approximately doubled the risk of depression (OR= 2.07, 95% CI: 1.49, 2.87; P<0.0001) and increased the risk of anxiety by almost 50% (OR= 1.56, 95% CI: 1.14, 2.14; P= 0.001). Adjustment for potential confounders just slightly changed the associations (OR for depression in the fourth quartile= 1.96; 95% CI: 1.34, 2.85, and OR for anxiety in the fourth quartile= 1.53; 95% CI: 1.07, 2.19). CONCLUSIONS: An unhealthy plant-based dietary index is associated with a higher risk of depression and anxiety, while plant-based dietary index and healthy plant-based dietary index were not associated to depression and anxiety

Effects of pioglitazone on asymmetric dimethylarginine and components of the metabolic syndrome in nondiabetic patients (EPICAMP Study): A double-blind, randomized clinical trial

The present trial aimed to investigate the effects of pioglitazone on the serum level of asymmetric dimethylarginine (ADMA), a marker of endothelial function, and some indices of inflammation and glucose and lipid metabolism in nondiabetic metabolic syndrome patients. 104 eligible participants (57 female; age between 20 and 70) were enrolled in a double-blind placebo-controlled trial and were randomized to receive either pioglitazone (uptitrated to 30 mg/day) or matching placebo for 24 weeks. Participants were clinically examined and a blood sample was obtained at baseline and at the end of the trial. Pioglitazone significantly improved C-reactive protein level irrespective of changes in insulin sensitivity. Compared with the placebo group, alanine and aspartate transaminases were decreased and high-density lipoprotein cholesterol was increased after treatment with pioglitazone. A considerably greater weight gain was also recorded in the intervention group. We failed to observe any significant changes in serum ADMA in either group and between groups with and without adjustment for age, sex, and components of the metabolic syndrome. In a nutshell, pioglitazone seems to have positive effects on lipid profile, liver transaminases, and systemic inflammation. However, its previously demonstrated endothelial function-improving properties do not seem to be mediated by ADMA. © 2013 Pedram Shokouh et al

Antithrombotic therapy in atrial fibrillation associated with valvular heart disease: A joint consensus document from the European Heart Rhythm Association (EHRA) and European Society of Cardiology Working Group on Thrombosis, endorsed by the ESC Working Group on Valvular Heart Disease, Cardiac Arrhythmia Society of Southern Africa (CASSA), Heart Rhythm Society (HRS), Asia Pacific Heart Rhythm Society (APHRS), South African Heart (SA Heart) Association and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE)

Atrial fibrillation (AF) is a major public health problem1 with global prevalence rates (per 1000000 population) in 2010 being 596.2 (95% uncertainty interval (UI), 558.4-636.7) in men and 373.1 (95% UI, 347.9-402.2) in women; the incidence rates increased to 77.5 (95% UI, 65.2-95.4) in men and 59.5 (95% UI, 49.9-74.9) in women.2 Worldwide, AF in association with valvular heart disease (VHD) is also common, and management strategies for this group of patients have been less addressed by randomized trials. The latter have largely focused on 'non-valvular AF' patients leading to major uncertainties over how to define (and treat) such patients. There is also an important heterogeneity in the definition of valvular and non-valvular AF.3 Some physicians assume that any valve disease should be considered as 'valvular' AF. Others consider that only mechanical valve prosthesis and rheumatic mitral stenosis should be defined as 'valvular' AF. The term valvular AF has been arbitrarily applied and the 2016 ESC guidelines have avoided the term 'valvular AF' and refer simply to 'AF related to hemodynamically significant mitral stenosis or prosthetic mechanical heart valves'.4 AF clearly leads to an incremental risk for thromboembolism in patients with mitral valve stenosis, but there are limited data for other valvular diseases. Another proposal is to use the acronym MARM-AF as a simple acronym to designate 'Mechanical and Rheumatic Mitral AF' as an alternative to term 'valvular AF' to designate the clinical scenarios for which at the non-vitamin K antagonist oral anticoagulants (NOACs) are not indicated.5 For this document we recognize the uncertainty in terminology, and our scope largely relates to AF related to 'hemodynamically significant' rheumatic VHD (ie. severe enough to impact on patient's survival or necessitates an intervention or surgery) or prosthetic mechanical heart valves. Nonetheless, thrombo-embolic (TE) risk varies according to valve lesion and may be associated with CHA2DS2VASc score risk factor components, rather than the valve disease per se being causal.6,7 TE risk may also be influenced not only by type but also the severity of the lesion. For example, the degree of mitral regurgitation may matter when it comes to risk of TE as some studies suggest that mild (Grade 1) mitral regurgitation is associated with a 2.7-fold increased risk of stroke/TE, while severe forms may possibly have a 'protective' effect (HR = 0.45 for stroke and 0.27 for LA stasis.8 An appropriate definition of 'valvular AF' would need to identify a subgroup of patients with similar pathophysiology of thrombo-embolism, TE risk, and treatment strategies6,9; however, this would be challenging given the major heterogeneity of the condition. This consensus document proposes that the term 'valvular AF' is outdated and given that any definition ultimately relates to the evaluated practical use of oral anticoagulation (OAC) type, we propose a functional EHRA (EvaluatedHeartvalves, Rheumatic orArtificial) categorization in relation to the type of OAC use in patients with AF, as follows:Evaluated Heartvalves, Rheumatic or Artificial (EHRA) Type 1,which refers to AF patients with 'VHD needing therapy with a Vitamin K antagonist (VKA)

Waterpipe smoking among health sciences university students in Iran: perceptions, practices and patterns of use

<p>Abstract</p> <p>Background</p> <p>In recent years waterpipe smoking has become a popular practice amongst young adults in eastern Mediterranean countries, including Iran. The aim of this study was to assess waterpipe smoking perceptions and practices among first-year health sciences university students in Iran and to identify factors associated with the initiation and maintenance of waterpipe use in this population.</p> <p>Results</p> <p>Out of 371 first-year health sciences students surveyed, 358 eight students completed a self-administered questionnaire in the classrooms describing their use and perceptions towards waterpipe smoking. Two hundred and ninety six responders met study inclusion criteria. Waterpipe smoking was common among first-year health sciences university students, with 51% of students indicating they were current waterpipe smokers. Women were smoking waterpipes almost as frequently as men (48% versus 52%, respectively). The majority of waterpipe smokers (75.5%) indicated that the fun and social aspect of waterpipe use was the main motivating factor for them to continue smoking. Of waterpipe smokers, 55.3% were occasional smokers, using waterpipes once a month or less, while 44.7% were frequent smokers, using waterpipes more than once a month. A large number of frequent waterpipe smokers perceived that waterpipe smoking was a healthier way to use tobacco (40.6%) while only 20.6% thought it was addictive. Compared to occasional smokers, significantly more frequent smokers reported waterpipe smoking was relaxing (62.5% vs. 26.2%, <it>p </it>= 0.002), energizing (48.5% vs. 11.4%, <it>p </it>= 0.001), a part of their culture (58.8% vs. 34.1%, <it>p </it>= 0.04), and the healthiest way to use tobacco (40.6% vs. 11.1%, <it>p </it>= 0.005).</p> <p>Conclusions</p> <p>Social and recreational use of waterpipes is widespread among first-year health sciences university students in Iran. Women and men were almost equally likely to be current waterpipe users. Public health initiatives to combat the increasing use of waterpipes among university students in Iran must consider the equal gender distribution and its perception by many waterpipe smokers as being a healthier and non-addictive way to use tobacco.</p
