Pericardial mesothelioma cyst occurs rarely, and is often found incidentally. The coexistence between large pericardial mesothelial cyst and hypertrophic obstructive cardiomyopathy (HOCM) can make difficulties in medical management.
CASE REPORTOur case was a 33-year-old man presented with dizziness and pallor while standing since four years before, and recent syncope. On admission, transthoracic echocardiography reveled presence of hypertrophic cardiomyopathy in association with relatively small right ventricular and atrium due to compression effect by a large echo-free space at the right side of heart suggestive of pericardial cyst. Cardiac computed tomography confirmed presence of HOCM and large pericardial cyst. Patient underwent surgical septal myectomy and large mesothelial pericardial cyst excision because of persistent symptoms and compression effect of cyst on the right chambers despite beta-blocker therapy.
CONCLUSIONTo best of our knowledge, the coexistence of the large pericardial mesothelial cyst and HOCM has not been reported before.

Resistin and oxidative stress may play a role in the pathogenesis of coronary heart disease (CHD) including acute coronary syndrome (ACS). The aim of this study was to investigate the role of serum resistin and prooxidant-antioxidant balance (PAB) in ACS occurrence in order to differentiate it from stable angina. Moreover, we aimed to determine the correlation between resistin and PAB in patients with ACS and its difference from patients with stable CHD.
METHODSThis cross-sectional, descriptive study was conducted on 50 patients with ACS and 50 patients with stable CHD who underwent coronary angiography (CAG). Serum resistin level was measured using enzyme-linked immunosorbent assay (ELISA). PAB and other variables were analyzed using standard methods.
RESULTSA significant increase in serum resistin and PAB was observed in patients with ACS (2.55 ± 0.13 ng/ml and 123.5 ± 5.58 HK unit, respectively) compared to patients with stable CHD (1.53 ± 0.12 ng/ml and 95.9 ± 2.7 HK unit, respectively) (P < 0.001). In addition, a significant positive correlation was seen between serum resistin and PAB in patients with ACS (r = 0.39; P = 0.005), but this correlation was not found in patients with stable CHD (r = 0.21; P = 0.140). Resistin (r = 0.52; P < 0.001) and PAB (r = 0.55; P < 0.001) were significantly associated with high-sensitivity C-reactive protein (hs-CRP) in patients with ACS, but this association was not found in patients with stable CHD (resistin: r = 0.24; P = 0.090; PAB: r = -0.02: P = 0.910).
CONCLUSIONHigh serum resistin or PAB levels, and their association with the occurrence of ACS, can be used as a robust discriminating factor to differentiate ACS from stable CHD.

Hypertension (HTN) is a public concern and treatment adherence has a key role in its management. This study was conducted to develop and test the reliability and validity of the Hypertensive Treatment Adherence scale (HTA-scale).
METHODSThis was a cross-sectional and methodological study. After item generation using a qualitative study and literature review, the scale was developed. The psychometric properties of the scale were evaluated using face, content, construct, and criterion validity and reliability.
RESULTSData analysis showed that the HTA-scale had acceptable face and content validity. The scale had excellent stability [Intraclass correlation coefficient (ICC) = 0.74] and good acceptability and internal consistency (Cronbach's = 0.76). Exploratory factor analysis (EFA) showed that the HTA-scale consisted of 6 meaningful subscales including medication adherence and monitoring, adherence to safe diets, avoiding unsafe diets, self-medication, activity, and smoking. Participants in the controlled blood pressure group had significantly higher HTA-scale scores than the uncontrolled blood pressure group. At the cut-off point of 86, the scale had significant sensitivity and specificity.
CONCLUSIONAll of the psychometric properties of the HTA-scale achieved the standard level and were sufficient to recommend this scale for patients with HTN.

According to the World Health Organization (WHO), non-communicable diseases (NCDs) including cardiovascular diseases (CVDs) will be responsible for almost 70% of all deaths in 2020. Therefore, knowledge production to find suitable ways to prevent, diagnosis, and effectively cover this disease in research centers is mandatory. Therefore, the present study is carried out with the aim to examine the results of studies performed in three years in Iranian cardiovascular centers.
METHODSIranian cardiovascular research centers with more than three years of activity from 2015 to 2017 were evaluated. Research output, international collaboration, high quality publication, total citation, and average h-index (H) were evaluated and scored.
RESULTS23 cardiovascular diseases research centers (CVDRCs) related to 15 universities of Medical Sciences (UMSs) were evaluated. The mean and standard deviation (SD) of age of the research activities in CVDRCs was 11.47 ± 8.60 years. Based on the research ranking, the first three centers were Isfahan Cardiovascular Research Center, Iran, Tehran Heart Center, and Shaheed Rajaei Cardiovascular Medical and Research Center, Iran, respectively, all of which have independent budget line. However, there is not any CVD research center in some provinces such as Zanjan, Kurdistan, Lorestan, and Arak, Iran.
CONCLUSIONMission oriented research activities in Iranian cardiovascular research centers may be effective in reducing the burden of CVDs. Moreover, establishment of CVD research centers in high risk areas may be useful.

High consumption of trans-fatty acids (TFAs) is introduced as dietary risk factor of cardiovascular diseases (CVDs). The accuracy of the information shown on the traffic light (TL) labelling has a significant influence on consumers to reduce TFA content in foods. This study is conducted aiming to determine the TFA content in traditional sweets distributed in Isfahan, Iran. Furthermore, the accuracy of the amount of TFAs on TL was considered by comparing it with the experimentally analyzed values.
METHODSIn this cross-sectional study, a total of 99 Iranian traditional sweets with a TL label were randomly collected from confectionary shops located in Isfahan. TFAs were analyzed by gas chromatography (GC).
RESULTSTFAs were detected in all samples with the total average of 1.6 ± 0.3% in total fat (range of 0.040 ± 0.001 to 7.900 ± 1.100%). More than half of the samples had less than 2% of TFAs in the total fat. Overall, 81.8% of the studied products with TL labelling showed a discrepancy in the TFAs in the values analyzed in laboratory.
CONCLUSIONIn the present study, the discrepancy of TFAs in the experimentally measured values with TL food labelling was observed in more than 80% of Iranian traditional sweets. Most of the samples contained less than 2% of TFAs that is defined as a limit in Iran Food and Drug Administration (IFDA). These findings could be alarming for the consumers of this kind of products.

The probable complications of 3 different cardiovascular diseases treatment options including percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), and medical therapy (MT), especially in individuals suffering from left main (LM) and/or three vessel diseases (3VDs), have received less attention. Thus, the aim of this study was to compare the complications of the aforementioned therapeutic strategies in patients admitted with LM coronary artery disease (CAD) and/or having 3VDs.
METHODSFrom March 2018 to March 2019, a total number of 251 eligible individuals (87, 86, and 78 subjects treated with PCI, CABG, and MT, respectively) were recruited in this cohort study. After the initiation of treatment, all individuals were followed for 6 months. Occurrence of any complications including chest pain (CP), re-hospitalization due to cardiac problems, heart failure (HF), death, myocardial infarction (MI), and stroke as well as major adverse cardiac events (MACE) were assessed.
RESULTSSignificantly lower percentages of CP, readmission, and HF were observed in the CABG group compared to the PCI and MT groups (24.4% vs. 47.1% and 53.9%, P < 0.001; 3.5% vs. 13.8% and 5.1%, P = 0.020; 1.2% vs. 2.3% and 9%; P = 0.040, respectively). Further analysis revealed an increased likelihood of hospitalization in the PCI group (OR: 3.82, 95% CI: 1.0114.41, P = 0.040), and a lower risk of CP and HF occurrence in the CABG group subjects compared to the MT group (OR: 0.28, 95% CI: 0.13-0.62, P = 0.002 and OR: 0.05, 95% CI: 0.004-0.71, P = 0.030, respectively). This pattern was also observed in the PCI group in terms of HF (OR: 0.12, 95% CI: 0.02-0.83, P = 0.030).
CONCLUSIONPatients suffering from LM and/or 3VDs would most likely benefit from CABG followed by PCI, rather than MT. Further large-scale studies are required to confirm these results.
