Cardiotoxicity is one of the main complications of chemotherapy that increases morbidity and mortality in cancerous patients. The present systematic review aimed to investigate the protective effects of berberine (Ber) on doxorubicin (Dox)-induced cardiotoxicity. The study protocol was developed following the PRISMA statement. An extensive search was performed in multiple databases, including Embase, PubMed, Cochrane library, Web of Science, and Scopus. After defining the inclusion/exclusion criteria of the study, 12 records were included. The desired data of the retrieved articles were extracted from the studies and imported into an Excel form and ultimately, the effects, probable outcomes and mechanisms were surveyed. By activating sirtuin 1 (SIRT1), Ber caused reduced oxidative damage and loss of mitochondria integrity in cardiomyocytes. It also regulated autophagy and apoptosis via down-regulating AMP-activated protein kinase (AMPK), nucleotide-binding oligomerization domain, leucine rich repeat, and pyrin domain containing protein (NLRP) activation. Moreover, Ber increased superoxide dismutase (SOD), catalase (CAT), and plasma glutathione peroxidase (GSH-Px) activities, reduced the levels of malondialdehyde (MDA), up-regulated SIRT3, and subsequently reduced oxidative stress in cardiomyocytes and loss of mitochondria integrity, leading to developed apoptosis and regulating the histopathological and electrocardiogram changes in the myocardium. It also ameliorated the DOX-induced calcium ions (Ca2+) and iron overload. Ber reduced oxidant and inflammatory activity, and regulated apoptosis of cardiomyocytes, thus protecting the cells against DOX-induced cardiotoxicity.

Background and aims
Atherosclerosis is one of the main reasons why people die from cardiovascular disease. The pathogenesis of atherosclerosis may have been aided by the deregulation of cellular and molecular events in peripheral blood mononuclear cells (PBMCs). This study aimed to investigate the alteration of the expression of matrix metallopeptidase-9 (MMP-9) in PBMCs of subjects who underwent angiography.
MethodsFollowing a thorough clinical examination and anthropometric assessments, 90 individuals were divided into two groups: 56 coronary artery disease (CAD) participants (subjects with coronary artery stenosis≥50%) and 34 non-CAD participants (subjects with coronary artery stenosis≤30%). Then, this study evaluated fasting serum glucose (FSG), total cholesterol (Chol), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and triglyceride (TG). Next, the severity of coronary artery stenosis was recorded. Additionally, real-time polymerase chain reaction (PCR) was used to assess the gene expression of MMP-9. MMP-9 protein level was also assessed using western blot techniques. The overexpression of MMP-9 and elevated level of FSG were positively associated with coronary artery stenosis.
ResultsOur results revealed that MMP-9 was upregulated both at the level of transcription and translation. Moreover, the upregulation of MMP-9 had a significant positive correlation with the severity of coronary artery stenosis.
ConclusionSignificant correlation between the overexpression of MMP-9 and coronary artery stenosis confirms our hypothesis that the upregulation of MMP-9 in PBMCs has an important role in the pathogenesis of atherosclerosis before monocyte recruitment and its subsequent processes.

Concomitant carotid artery disease (CaAD) in patients referred to coronary surgical revascularization is a strong hazard to perioperative stroke. The current study addressed the epidemiology features of concomitant CaAD in patients referred to a coronary surgical revascularization center.
MethodsThis descriptive-analytical cross-sectional study was conducted on all incoming patients to coronary surgical revascularization for two years at a single center who underwent a color duplex-sonography (CDS) interrogation. The demographic, clinical, echocardiographic, coronary angiographic, and color duplex-sonographic data were collected from patients’ medical records. Quantitative and qualitative data were expressed as means and standard deviations, as well as numbers and percentages, respectively. The relationships between quantitative and qualitative variables were investigated using Pearson’s correlation and chi-square test, respectively.
ResultsIn total, 430 patients with a mean age of 66.3±9.9 years were included (35% females) in the study. Preoperative CDS was performed on 82% of patients; in addition, 29% of them presented with an increased intima-media ratio, and CtAD was observed in 51%. Based on the results, 77 and 143 patients were detected with unilateral and bilateral involvement, respectively. Severe carotid stenosis accounted for 4% of patients. Age older than 65 years (P=0.02), unstable angina (P=0.045), and the presence of an occluded coronary artery (P=0.002) were associated with the presence of CtAD. Finally, the severity of the left and right carotid stenosis was associated with diabetes mellitus (P<0.05).
ConclusionThe prevalence of concomitant CtAD in patients referred to coronary surgical revascularization remains high. The current data warn of the necessity of performing preoperative CDS routinely.

BackgroundMyocardial infarction (MI) is a life-threatening condition affecting an individual's physical and social circumstances. Life expectancy and self-efficacy are required to determine the risk of cardiac complications associated with this disease. This study examined the effect of family-centered intervention via short message service (SMS) on patients with acute MI's life expectancy and self-efficacy in medication regimens.MethodsThis study was a randomized, single-blind clinical trial. In 2018, 80 patients hospitalized with acute MI at educational centers affiliated with Shahrekord University were randomly assigned to the control and experimental groups. Routine intervention was performed in the control group. The experimental group was sent four educational text messages weekly for three months. Both groups' life expectancy and belief in their ability to adhere to their prescribed medication regimen were evaluated before and after the intervention. The data were analyzed using descriptive statistics, independent t, paired t, and chi-square tests via SPSS software.ResultsThe results showed that the mean difference score of total life expectancy change was significantly different between the experimental (12.23± 10.48) and the control group (0.06±7.16) (p < 0.001). The mean difference score of self-efficacy in the experimental group (21.94±12.76) was significantly higher than that in the control group (4.66±9.49) (P<0.001).ConclusionsIn patients with acute MI, using a text message intervention improved life expectancy and self-efficacy regarding medication regimens. Therefore, this intervention can be used as a low-cost and readily accessible tool to improve these patients' self-efficacy and life expectancy.Keywords: Myocardial Infarction, Self-Efficacy, Life Expectancy, Short message service

Background and aims
Acute myocardial infarction (MI) is one of the most prevalent heart diseases across the world, including in Iran. The purpose of the present study was to investigate the relationship between acute MI and serum low-density lipoprotein (LDL) levels in patients with acute MI.
MethodsIn this descriptive-inferential study, 1274 MI patients hospitalized in Shahrekord Hajar Hospital were selected using the census method. The required information was drawn from the patient’s medical records according to inclusion criteria. Statistical analyses were performed using analysis of variance (ANOVA) and chi-square test to examine the relationship between the LDL level and awareness in patients.
ResultsIn this study, the average age of patients with acute heart attack was 13.79±63.18 years. Of the 1274 studied patients, 78% (999 people) were men and the rest were women. In both male and female genders, most patients had LDL levels between 70 and 129 mg/dL. Regarding statin use, 757, 287, and 162 people had a history of statin use, hypertension (HTN), and cardiovascular disease, respectively. In addition, 150 and 152 people had diabetes and a history of smoking, respectively. In this study, a significant relationship was found between the history of statin use (P<0.0001) and the frequency of MI (P=0.049) in LDL groups.
ConclusionThe results of this research revealed a significant relationship between LDL groups and the number of times acute heart attack occurs as a long-term complication in people who have had one.

Background
Anxiety is one of the most common psychological problems after myocardial infarction and can lead to many problems in acute coronary syndrome (ACS). Two possible ways to reduce anxiety are to listen to music and to recite the Holy Quran, the effects of which have never been compared to date.
ObjectivesThe aim of this study was to compare the effect of listening to instrumental music and listening to Quran recitation on the anxiety level of patients with acute coronary syndrome.
MethodsThis semi-experimental study was conducted among 96 patients with ACS referred to Hajar Hospital, Shahrekord, Iran, from 3/10/2019 to 4/30/2019. The patients were entered into the study using the convenience sampling method and then randomly assigned to the three groups of Quran recitation, instrumental music, and control. In this study, the patients’ anxiety level was measured using Spielberger’s state-trait anxiety inventory (STAI) before and after listening to Quran recitation and instrumental music. Data were analyzed by SPSS version 16 using descriptive and analytical tests, including paired samples t-test, Chi-square, and one-way ANOVA.
ResultsAnxiety level decreased from 43.1 ± 6.15 to 38.5 ± 3.82 in Quran recitation group (P < 0.001) and from 44.2 ± 1.21 to 39.1 ± 4.17 in the instrumental music group (P = 0.035), and from 46.3 ± 3.84 to 44.7 ± 6.21 in the control group (P < 0.001). There was no significant difference between the three groups before the program. However, the mean score of anxiety level showed a significant difference, indicating that listening to Quran recitation had a greater effect than listening to instrumental music in reducing the patients’ anxiety (P = 0.02).
ConclusionsBoth interventions can be useful in decreasing the anxiety level of patients with ACS; however, the Holy Quran recitation had a greater effect in this regard.

BACKGROUNDObesity is a major risk factor for many diseases including cardiovascular diseases (CVDs). Recently, it has been shown that upper body obesity can predict CVDs per se. In this study, we aimed to determine the association between indicators of upper body obesity and echocardiographic indices.METHODSIn this cross-sectional study conducted in Hajar Hospital in Shahrekord, Iran, from March to August 2014, 80 healthy adults were included. Participants’ neck circumference (NC), waist circumference (WC), body mass index (BMI), and blood pressure were measured. Echocardiography was performed for all participants, and echocardiographic indices such as early (E’) and late (A') diastolic tissue velocity, early (E) and late (A) transmitral flow velocity, E/E’ ratio, pulmonary arterial pressure (PAP), and left atrial volume (LAV) were recorded. The association between these indices were investigated using bivariate Pearson correlation coefficient.RESULTSFor men, NC had a significant correlation with LAV, systolic blood pressure (SBP), diastolic blood pressure (DBP), PAP, and A', and a negative correlation with E′. WC had a significant correlation with LAV, SBP, and PAP, and a negative correlation with E′, while BMI had a significant correlation with LAV, PAP, SBP, A, and A’. For women, NC had a significant positive correlation with LAV, A, ejection fraction (EF), SBP, PAP, and A’, and a negative correlation with E′ and E/E′. WC had a significant positive correlation with LAV, DBP, PAP, A, A’, and a negative correlation with E′, while BMI had a significant correlation with LAV, EF, SBP, PAP, E’, A, and A’.CONCLUSIONThe positive correlation of NC with SBP, A, and A', as well as NC, WC, and BMI with LAV and PAP in both sexes, and the negative correlation of NC with E′ show the importance of these measures in estimation of metabolic and cardiovascular risk factors.Keywords: Obesity, Risk Factor, Cardiovascular Diseases

Recurrent short episodes of bradycardia and hypotension are rarely reported as clinical manifestations of pulmonary thromboembolism (PTE). We report a case of acute massive PTE presenting with dyspnea, burning chest pain with physical activity, and recurrent transient bradycardia and hypotension at rest. Echocardiography showed a left ventricular ejection fraction of 45% with global hypokinesia. Computed tomography angiography showed a large pulmonary thromboembolism. Lytic therapy improved the right ventricular function, and the pulmonary artery pressure decreased to 38 mmHg. Recurrent bradycardia and transient hypotension at rest with syncope on activity and recovery without treatment are not common and may suggest a vasovagal mechanism. Evaluation of patients with these clinical findings could enable early diagnosis and treatment of acute PTE, with decreased morbidity and mortality.Keywords: Pulmonary thromboembolism, Bradycardia, Syncope

BackgroundComplementary medicine interventions are now successfully used to reduce stress as well as to stabilize hemodynamic indices within different procedures. The present study aimed to examine the effect of massage therapy and reflexotherapy on reducing stress in patients before coronary angiography.MethodsIn this open-label clinical trial, 75 consecutive patients who were candidate for coronary angiography were randomly assigned to receive reflexotherapy (n = 25), or massage therapy (n = 25), or routine care (n = 25) before angiography. The Spielberger State-Trait Anxiety Inventory was used to determine the stress level of patients before and after interventions and vital signs were also measured.ResultsImprovement in diastolic blood pressure, heart rate, and respiratory rate was shown in the reflexotherapy group, and similar effects were observed following other interventions including massage therapy and routine resting program. In subjects who received reflexotherapy the level of stress decreased slightly compared with the other two groups. However, following interventions the level of stress in reflexotherapy group was shown to be lower than other study groups.ConclusionReflexotherapy before coronary angiography can help to stabilize vital sign as well as reduce the level of stress. The effect of massage therapy was limited to reducing stress.Keywords: Reflexotherapy, Massage Therapy, Coronary Angiography, Vital Signs, Emotional Stress

BackgroundThe data and determinants of mortality due to stroke in myocardial infarction (MI) patients are unknown. This study was conducted to evaluate the differences in risk factors for hospital mortality among MI patients with and without stroke history.Materials And MethodsThis study was a retrospective, cohort study; 20,750 new patients with MI from April, 2012 to March, 2013 were followed up and their data were analyzed according to having or not having the stroke history. Stroke and MI were defined based on the World Health Organizations definition. The data were analyzed by logistic regression in STATA software.ResultsOf the 20,750 studied patients, 4293 had stroke history. The prevalence of stroke in the studied population was derived 20.96% (confidence interval [CI] 95%: 20.1321.24). Of the patients, 2537 (59.1%) had ST‑elevation MI (STEMI). Mortality ratio in patients with and without stroke was obtained 18.8% and 10.3%, respectively. The prevalence of risk factors in MI patients with and without a stroke is various. The adjusted odds ratio of mortality in patients with stroke history was derived 7.02 (95% CI: 5.429) for chest pain resistant to treatment, 2.39 (95% CI: 1.972.9) for STEMI, 3.02 (95% CI: 2.53.64) for lack of thrombolytic therapy, 2.2 (95% CI: 1.662.91) for heart failure, and 2.17 (95% CI: 1.62.9) for ventricular tachycardia.ConclusionWith regards to the factors associated with mortality in this study, it is particularly necessary to control the mortality in MI patients with stroke history. More emphasis should be placed on the MI patients with the previous stroke over those without in the interventions developed for prevention and treatment, and for the prevention of avoidable mortalities.Keywords: Mortality, myocardial infarction, risk factor, stroke

P < 0.05 was considered as statistically significant..ResultsIn-hospital mortality rate was 12.1% (N = 2511) and female/male ratio of CFR was 1.36 (95% CI: 1.2 - 1.4). Besides, in-hospital CFR was 8.36: 7.81 - 8.94 in females and 6.12: 5.83 - 6.43 in males. Hazard ratio of mortality for ST segment Elevation Myocardial Infarction (STEMI), chest pain resistant to treatment, and Right Bundle Branch Block (RBBB) was 1.32, 4.06, and 2.45, respectively (P < 0.01). Using Percutaneous Coronary Intervention (PCI) decreased the risk of death in the patients (HR: 0.68). Overall, 83.7% of the patients with STEMI died..ConclusionsIn Iran, identifying the risk factors of mortality due to MI could contribute to detecting high-risk individuals and improving healthcare by relevant planning and interventions in clinics and communities..Keywords: Proportional Hazards Models, Hospital Mortality, Myocardial Infarction

Background
This study aimed to find the influence of education level on the trends of changes of these risk factors among a great sample of Iranian population.
Materials and MethodsThis cross‑sectional study is a secondary analysis of Isfahan Healthy Heart Program (IHHP). Blood samples were taken to determine the lipid levels including total cholesterol (TC), low‑density lipoprotein cholesterol (LDL‑C), low levels of high‑density lipoprotein cholesterol (HDL‑C), and triglycerides. Education categorized based on training system in Iran as 1‑5, 6‑12, and more than 12 years training.
ResultsThe prevalence of diabetes was higher among illiterate participants in both areas. Hypertension was more prevalent in illiterate subjects (2001; 44.0% and 2007; 46.3%) in intervention area (P < 0.001). Dyslipidemia was more prevalent among illiterate people (P < 0.001). In the intervention, illiterates have higher BMI in both 2001 and 2007 (P < 0.001). The prevalence of current smoking was the highest in education level range 6 to 12 years and was steadily decreased in higher education levels (P < 0.001). Subjects with 6‑12 years of education have more unhealthy nutritional habits in both areas. In 2001, subjects with 12 years of education or more had more physical activity than other groups (P < 0.001), whereas, in 2007, subjects with 6‑12 years of education were more active (P < 0.001).
ConclusionAlthough the prevalence of diabetes, hypertension obesity, and dyslipidemia are more in illiterate subjects and prevalence of diabetes and hyperlipidemia was sharply decreased with education level, it seems that well educated participants have higher daily physically activity compared with those who have lower education without considering the place or residency.

Background
This study aims to evaluate the impact of the Isfahan Healthy Heart Program (IHHP) interventions concerning healthy behavior, on the prevalence of the metabolic syndrome (MetS) and its components in the Iranian population.
Materials and MethodsThe IHHP targeted the population at large in three districts in central Iran from 2000 to 2007. Numerous interventional activities were performed to improve lifestyle. The main intervention strategies were public education through mass media, intersectional cooperation, health professional education, marketing and organizational development, legislation and policy development, as well as research and evaluation. MetS was defined based on the Adult Treatment Panel (ATP) III definition. The logistic regression method was applied to explore the relationship between lifestyle factors with components of metabolic risk factors.
ResultsThe mean age of the participants was 44.68 ± 14.43 years in 2001. The mean values of the MetS components differed from 2001 to 2007. The mean of systolic blood pressure (SBP) decreased from 126.7 ± 22.31 to 124.21 ± 20.0 and from 129.47 ± 23.08 to 126.26 ± 21.88 among females in both the intervention and reference areas. Similar changes were observed among males. The mean diastolic blood pressure (DBP) and triglycerides decreased significantly in the intervention area and increased significantly in the reference area in both sexes. High density protein cholesterol (HDL-C) was decreased in both sexes, from 2001 to 2007, in both areas. A strong relationship between tobacco control with high SBP and hypertriglyceridemia was found (P < 0.01).
ConclusionLifestyle improvement programs could be useful to improve the MetS status among men and women.

سابقه و هدفسندرم حاد کرونر شامل سکته قلبی با و بدون بالارفتن قطعه ST و آنژین ناپایدار می باشد. ویژگی های اپیدمیولوژیک این بیماران و عوامل تعیین کننده مرگ و میر آن ها در ایران تا کنون بررسی نشده است. این مطالعه با هدف تعیین ویژگی های بیماران مبتلا به سندرم حاد کرونر و تعیین کننده های مرگ و میر آن ها در ایران انجام گردیده است.مواد و روش هامطالعه حاضر به صورت هم گروهی آینده نگر مبتنی بر بیمارستان بوده است. هم گروه بیماران با توجه به تاریخ ابتلا به سندرم حاد کرونر و تاریخ بستری در بیمارستان، مدت بستری و تاریخ ترخیص از بیمارستان به دلیل مرگ یا بهبودی نسبی تعریف شد. بیماران از تاریخ تشکیل هم گروه تا زمان رخداد واقعه پیگیری شدند. در این مطالعه از اطلاعات 20750 بیمار مبتلا به سکته های قلبی کلیه بیمارستان های دارای بخش قلب در 31 استان ایران به عنوان هم گروه استفاده شد. برای تعیین فاکتورهای مرتبط با مرگ و میر بیماران از رگرسیون کاکس (مدل مخاطرات تناسبی) و محاسبه نسبت مخاطره استفاده شد.یافته هامیزان بروز مرگ در هزار شخص- سال در بیماران پی گیری شده سکته قلبی با و بدون بالا رفتن قطعه ST به ترتیب 4/ 3698 و 3/ 4573 در هزار نفر– سال بود. میانگین و انحراف معیار سن بیماران مبتلا به سکته قلبی با بالا رفتن قطعه ST 13/1± 60/5 سال و در بیماران بدون بالارفتن قطعه ST 13/4± 9/62 سال بود. شیوع دیابت نوع دو و فشارخون بالا به ترتیب در بیماران 2/ 22درصد و 5 /35درصد بود. شیوع سکته قلبی با بالا رفتن قطعه ST در بیماران 8/ 75درصد و شیوع سکته قلبی بدون بالا رفتن قطعه ST در بیماران 2/24درصد بود. سن بالاتر از 84 سال، جنسیت زن، بی سوادی، عدم دریافت درمان ترومبولیتیک، سابقه خانوادگی، درد قفسه سینه قبل از ورود به بیمارستان و درد مقاوم به درمان، انسداد شاخه راست قلب، تاکیکاردی بطنی، سکته قلبی با بالارفتن قطه ST، نارسایی قلب و دریافت آنژیوپلاستی مهم ترین تعیین کننده های مرگ بیماران بودند.استنتاجالگوی غالب نوع سکته در بیماران ایرانی، سکته قلبی با بالا رفتن قطعه ST بود. گزارش ویژگی های بیماران مبتلا به سندرم حاد کرونر و عوامل تعیین کننده مرگ و میر در آن ها می تواند در اتخاذ استراتژی و تصمیم گیری کارکنان نظام سلامت و نحوه ارزیابی، پایش، مراقبت و درمان و نحوه برخورد با بیماران کمک کننده باشد. از جمله استراتژی های مهم می توان آموزش به مردم برای مراجعه به اورژانس در صورت داشتن علائم سندرم کرونر حاد و دسترسی و دریافت درمان در وقت طلایی و پیشگیری از مرگ های قابل اجتناب را نام برد.
کلید واژگان: سندرم کرونر حاد, مرگ و میر, سکته قلبیBackground andPurposeAcute coronary syndrome (ACS) includes ST elevation myocardial infarction (STEMI)، non–ST-segment elevation myocardial infarction (NSTEMI)، and unstable angina. This study was conducted to determine the characteristics of patients with ACS and determinants of their mortality in Iran.Materials And MethodsThis study was a hospital-based prospective cohort study in which we used the data of 20،750 patients registered in National Registry of myocardial infarction in hospitals with cardiology ward in 31 provinces in Iran. To determine the factors associated with patients’ mortality، Cox regression (relative hazards model) was used.ResultsMortality rate in followed up patients with STEMI and NSTEMI was 3698. 4 and 4573. 3 per 1000 person-year، respectively. The mean age of patients with STEMI was 60. 5± 13. 1 years and in those with NSTEMI was 62. 9± 13. 4 years. The prevalence of STEMI and NSTEMI was 75. 8% and 24. 2%، respectively. The most important determinants of mortality in patients were age over 84 years of old، female sex، illiteracy، lack of receiving thrombolytic therapy، right bundle branch block، STEMI، heart failure، and receiving angioplasty.ConclusionThe characteristics of patients with ACS، could help the health system personnel in strategy adoption and decision making as well as assessment، monitoring، and treatment of patients. Training people to refer early for emergency care in case of manifesting ACS symptoms، and providing them with treatment at golden time could be of great benefit in reducing the rate of mortality.Keywords: Acute coronary syndrome, mortality, myocardial infarction -
BackgroundEjection fraction promotion in heart failure patients reduces mortalities and limitations..ObjectivesThis study was to investigate the effect of exercise on ejection fraction of chronic heart failure patients..Patients andMethodsThe present study was conducted on patients with chronic heart failure. 66 patients were divided randomly into two experimental and control groups of 33 each. The subjects were male and female. The patients in experimental group followed an exercise program three sessions per week for 24 weeks.

BackgroundIt is now hypothesized whether restricted salt intake can be a potential precursor to renal dysfunction in mild hypertension state. We aimed to study the association between salt intake and renal function in patients with mild hypertension.MethodsOne hundred consecutive hypertensive Iranian patients (with systolic blood pressure 140-160 mmHg and/or diastolic 90-100 mmHg) who were referred to the hypertension research center, Isfahan, Iran, between 2011 and 2014 for screening of hypertension were assessed. Renal function was assessed by measuring serum creatinine (Cr) and creatinine clearance (CrCl). Daily salt intake was assessed on the basis of 24 h urinary sodium excretion.ResultsThere was no association between the amounts of sodium intake and serum Cr concentration (r = 0.138, P = 0.174), however, an association was revealed between sodium intake and value of CrCl (r = 0.303, P = 0.003). Multivariable linear regression model showed that sodium intake could effectively predict renal function assessed by CrCl (Beta = 0.070, P = 0.016).ConclusionThere is an association between sodium intake and reservation of renal function in mild hypertension state and thus by restriction of dietary salt intake, reserving renal function, and preventing appearance and progression of renal insufficiency in higher degrees of hypertension can be facilitated.Keywords: Dietary, Salt Intake, Renal Function, Mild Hypertension
