Abstract
BACKGROUND The dimensional seat design process should consider both the users' tasks and their physical characteristics. OBJECTIVE To use an approach for the design and evaluation of seat dimensions based on the anthropometric characteristics of the Iranian population and the requirements of tractor operators. METHODS Some existing equations relating the seat dimensions to anthropometric characteristics were modified according to logical justifications and international standards. A new mathematical-statistical method was used to extract the equations estimating the constant seat dimensions based on the theoretical maximizing of the accommodation level. In addition, an Overall Seat Accommodation Score (OSAS) was developed to represent the mean of seat dimensions accommodation level and dimensional accommodation equality, simultaneously. RESULTS The dimensional seat design can be affected under different conditions of adjustability, esthetic, and space limitations. However, it was shown that it is possible to improve the design of tractor seats without any significant increase in the final cost and complexity. CONCLUSION A new approach was used for tractor seats for a sample of Iranian operators and can be used for the design and evaluation of tractor seats for other target populations.

Abstract
Sodium-glucose cotransporter-2 inhibitors (SGLT2is) reduce morbidity and mortality for heart failure (HF) patients and are recommended as cornerstones for their medical therapy. Utilization in clinical practice remains low for multiple reasons, one of which may be adverse events. We investigated the incidence of these events to see if they are associated with SGLT2i use. A systematic search was performed in databases, including PubMed, Embase, Cochrane Library, Clinicaltrials.gov, and WHO's International Clinical Trials Registry Platform. Relevant randomized controlled trial studies assessing the safety outcomes of SGLT2i in HF patients were included in this study. We conducted the common-effect meta-analysis to estimate the relative risk (RR) and 95% confidence interval (CI) of safety outcomes in SGLT2i compared with placebo. Eighteen studies were included in the meta-analysis composed of 12 925 HF patients taking an SGLT2i and 12 747 taking a placebo. The meta-analysis indicated that the all-cause mortality and serious adverse events (SAEs) were lower in the SGLT2i group (RR, 0.91; 95% CI, 0.85-0.97; P = 0.005, I2 = 0%; and RR, 0.92; 95% CI, 0.90-0.95; P < 0.001, I2 = 43%, respectively). Volume depletion and genitourinary infections were more prevalent in the SGLT2i group (RR, 1.17; 95% CI, 1.06-1.28; P = 0.001, I2 = 0%; and RR, 1.27; 95% CI, 1.13-1.43; P < 0.001, I2 = 17%, respectively). Our meta-analysis demonstrated that using SGLT2is in HF patients was correlated with reduced mortality and SAEs, with a more prominent effect in HF with reduced ejection fraction patients and those taking dapagliflozin.

Abstract
BACKGROUND AND OBJECTIVE Patients with heart failure experience high hospitalization. However, patients cannot recognize symptoms according to current approaches, which needs to be improved by new self-monitoring instruments and strategies. Thus, we aimed to assess a self-monitoring traffic light diary on outcomes of patients with heart failure. METHODS This was a single-blind, two-arm parallel group randomized controlled trial at the heart failure clinic of Tehran Heart Center (Tehran, Iran). Adult patients with a definitive diagnosis of heart failure with reduced ejection fraction (i.e., ejection fraction of less than 40 %), and New York Heart Association functional classes II-IV were included. A block-balanced randomization method was used to assign eligible subjects to the intervention or control group. Baseline data were collected before random allocation. Participants in the intervention group received a comprehensive intervention consisting of (1) self-care education by an Australian Heart Foundation booklet on heart failure, (2) regular self-monitoring of weight and shortness of breath at home, and (3) scheduled call follow-ups for three months. Patients in the control group received usual care. The primary outcome was heart failure self-care; the secondary outcomes were heart failure quality of life, knowledge, and all-cause hospitalization. RESULTS From June to August 2017, 68 patients were included in the study. The overall age of participants was 55 (13.6) years old, and 71 % of patients were male. A significant association between the intervention and self-care maintenance (β 5.1; 95 % CI 2.50 to 7.70, P < 0.001), self-care management (β 10.6; 95 % CI 6.50 to 14.8, P < 0.001), self-care confidence (β 8.0; 95 % CI 5.0 to 11.0, P < 0.001) and heart failure knowledge (β 1.7; 95 % CI 1.30, 2.04; P < 0.001) was found. However, there was no association between the intervention and quality of life (β 2.5; 95 % CI -0.79, 5.88, P 0.135) and hospitalization-free survival of the two groups (Log-Rank P 0.540). CONCLUSION A self-monitoring traffic light diary can improve self-care behaviors and heart failure knowledge in patients with heart failure with reduced ejection fraction.

Abstract
BACKGROUNDS Omega-3 supplements are endorsed for heart failure (HF) patients to reduce hospitalizations and mortality, offering anti-inflammatory and cardioprotective benefits. METHODS A comprehensive search was conducted in various databases until November 2022. Eligible studies included clinical trials on patients with HF. Data extraction covered study details, omega-3 specifics, outcomes, and limitations. The JADAD scale was used to assess the risk of bias in randomized controlled trials. RESULTS The review process involved 572 records from database searches, resulting in 19 studies after eliminating duplicates and screening. These studies assessed the impact of omega-3 on various clinical outcomes, such as mortality, hospitalization, cardiac function, and quality of life. Studied duration varied from weeks to years. Omega-3 supplementation demonstrated potential benefits such as improved heart function, reduced inflammation, and decreased risk of cardiovascular events. CONCLUSION Omega-3 supplementation could benefit heart disease treatment, potentially reducing therapy duration and improving outcomes. Starting omega-3 supplementation for HF patients seems favorable.

Abstract
We aimed to review the validity of existing prediction models for cardiovascular diseases (CVDs) in Asia. In this systematic review and meta-analysis, we included studies that validated prediction models for CVD risk in the general population in Asia. Various databases, including PubMed, Web of Science conference proceedings citation index, Scopus, Global Index Medicus of the World Health Organization (WHO), and Open Access Thesis and Dissertations (OATD), were searched up to November 2022. Additional studies were identified through reference lists and related reviews. The risk of bias was assessed using the PROBAST prediction model risk of bias assessment tool. Meta-analyses were performed using the random effects model, focusing on the C-statistic as a discrimination index and the observed-to-expected ratio (OE) as a calibration index. Out of 1315 initial records, 16 studies were included, with 21 external validations of six models in Asia. The validated models consisted of Framingham models, pooled cohort equations (PCEs), SCORE, Globorisk, and WHO models, combined with the results of the first four models. The pooled C-statistic for men ranged from 0.72 (95% CI 0.70 to 0.75; PCEs) to 0.76 (95% CI 0.74 to 0.78; Framingham general CVD). In women, it varied from 0.74 (95% CI 0.22 to 0.97; SCORE) to 0.79 (95% CI 0.74 to 0.83; Framingham general CVD). The pooled OE ratio for men ranged from 0.21 (95% CI 0.018 to 2.49; Framingham CHD) to 1.11 (95%CI 0.65 to 1.89; PCEs). In women, it varied from 0.28 (95%CI 0.33 to 2.33; Framingham CHD) to 1.81 (95% CI 0.90 to 3.64; PCEs). The Framingham, PCEs, and SCORE models exhibited acceptable discrimination but poor calibration in predicting the 10-year risk of CVDs in Asia. Recalibration and updates are necessary before implementing these models in the region.

Abstract
Treatment adherence is a fundamental aspect of heart failure (HF) management. This study aimed to explore the experiences of facilitators and inhibitors of treatment adherence in patients with HF. This descriptive qualitative study was conducted from May 2020 to June 2021. Participants including people with HF, their family caregivers and physicians, and nurses were selected purposefully, with the aim of obtaining sufficient information power. Semi-structured interviews were used to collect data. Data were analyzed using thematic analysis. Two main themes "the driving forces behind treatment adherence" and "the deterrent forces behind treatment adherence" emerged from the analysis. The first theme contained the following subthemes: "supportive family," "positive personality characteristics," and "having health literacy." The second theme consisted of "negligence," "psychological problems," "cultural, social, and economic problems," "physical limitations," and "lack of self-care management knowledge." Nurses can consider facilitators and inhibitors of treatment adherence in designing educational and care programs for patients with HF.

Abstract
The occurrence of hematuria during a right heart catheterization can be a sign of renal perforation, a rare but life-threatening complication that could be developed due to the misdirection of wire into the abdominopelvic venous plexus. We showed this complication could be managed with venoplasty of the common iliac vein.

Abstract
Purpose
Post cardiac surgery hypotension and inotrope dependence are among major causes of prolonged intensive care unit (ICU) stay. Besides routine managements, catecholamine inotrope-vasopressors are the traditional treatment. However, there is an increasing interest to catecholamine-sparing agents, such as Midodrine, oral alfa1 agonist, in patients with vasoplegia. Up to now there are no randomized study with midodrine on post cardiac surgery patients.
Material and method
In this pilot, open label, assessor blind, randomized clinical trial from June 2020 to December 2021, 65 patients with refractory (more than 24 hours inotropes) hypotension after coronary revascularization were included. Patients were randomly assigned to receive Midodrine add-on therapy (10 mg stat and 5 mg po every 12 hours) or placebo add-on routine treatment. The primary outcome was liberation time from IV inotrope-support. Secondary outcomes were ICU admission time and total vasopressor dosage after randomization.
Results
32 patients enrolled in Midodrine group, with a mean age of 60.72, and 33 patients received placebo with mean age of 63.27. Median liberation time from inotrope was 27 hours in Midodrine group and 49 hours in placebo group (p=0.022). ICU admission time for Midodrine and placebo groups were 115 and 121 hours, respectively (p=0.990). Total vasopressor dosage after randomization were similar in two studied groups, 4352 μg in Midodrine group and 5637 μg in placebo group (p=0.405). No adverse event was observed in Midodrine group.
Conclusion
Midodrine add-on inotrope therapy was a safe medication with appropriate compliance in ICU admitted patients after cardiac surgery, which seems to decrease the inotrope dependent time.

Abstract
BACKGROUND & AIMS Heart failure (HF), as a major cardiac disease, is associated with considerable mortality, morbidities and poor quality of life. The aim of this study was to investigate the effect of l-arginine supplementation on cardiac outcomes and quality of life in patients with ischemic HF. METHODS This double-blind randomized controlled clinical trial was conducted in 50 patients with ischemic HF. Patients were randomly assigned to receive either 3 gr/d l-arginine or placebo, for 10 weeks. Cardiac function (based on echocardiography and six-minute walk test), blood pressure, and quality of life (based on the Minnesota living with heart failure questionnaire) were assessed. RESULTS The results showed significant improvements in ejection fraction (-6.5 ± 8.7 vs. -0.7 ± 7.8%, P = 0.037), left ventricular function (P = 0.043), diastolic dysfunction (P = 0.01) and marginally improvement in changes of left ventricular dimension during diastole (LVDd) (4 ± 6 vs. 0.3 ± 6.9 mm, P = 0.065) in the l-arginine compared to the placebo group. At the end of the study, physical aspect (5.7 ± 3.3 vs. 1.2 ± 6.1, P = 0.002) and total score (10 ± 6.7 vs. 4.1 ± 9.4, P = 0.011) of quality of life improved significantly in the l-arginine compared with the placebo group. Additionally, pre-to post-values of diastolic blood pressure, mean arterial pressure, LVDd, LV ejection fraction, left ventricular function, diastolic dysfunction as well as physical and total scores of quality of life improved significantly within the intervention, but not the placebo, group (all P < 0.05). CONCLUSION This study showed that 3 gr/d l-arginine supplementation for 10 weeks could improve cardiac recovery and function, and quality of life in patients with HF. This study was registered at the Iranian Clinical Trial Registration Center (www.irct.ir) with IRCT20170202032367N4 code.

Abstract
Abstract
Background
Spontaneous coronary artery dissection (SCAD) is a rather rare cause of acute coronary syndrome with a preponderance for young female patients. Amphetamines are now the second most widely used substance drugs in the world and they are associated with a myriad of cardiac diseases including cardiomyopathies and SCADs. There is much uncertainty regarding the best treatment strategy in such cases and decision-making remains mostly individualized and based on expert opinions.
Case presentation
A 34-year-old male with an unremarkable past medical history presented to a cardiologist with prominent dyspnea and orthopnea. He reported occasional methamphetamine use from 3 years before the presentation. An echocardiogram showed an enlarged left ventricle and severe systolic dysfunction with an ejection fraction of 10–15%. Coronary angiography revealed multiple linear dissections in both left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX). The patient’s right coronary artery (RCA) showed occlusion in the proximal segment. The patient was diagnosed with amphetamine-induced spontaneous coronary artery dissection and resultant ischemic cardiomyopathy. After thorough evaluation, medical treatment ensued.
Conclusions
Methamphetamine abusers have a 3.7 fold risk of developing some form of a cardiomyopathy in comparison to individuals without amphetamine abuse. Coronary artery dissection and increased thrombus burden are some of the mechanisms responsible for ischemic cardiomyopathy in these groups of patients.

Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory condition that most commonly affects the axial skeleton. The most common cardiac manifestation in patients with AS is the aortic root and valve disease, followed by conduction and rhythm abnormalities, decreased coronary flow reserve, myocardial infarction, and diastolic dysfunction. However, the presence of systolic dysfunction has been less described in patients with AS. Herein we present two cases of idiopathic dilated cardiomyopathy in patients with AS. These patients were noted to have an improvement of their ejection fraction following treatment of AS. Clinical and echocardiographic improvement on anti-inflammatory treatment might be a clue to the inflammatory nature of this myocardial problem, and further investigations to study the issue is required.

Abstract
Sildenafil is a selective phosphodiesterase-5 inhibitor and causes vasodilatation, particularly in pulmonary circulation. Since left heart failure may be associated with pulmonary hypertension "out of proportion to left heart disease," sildenafil may have beneficial effect in such patients. The present investigation was designed as a 12-week, single-center, randomized, double-blind, placebo-controlled study evaluating the effects of sildenafil on mean blood pressure (primary endpoint) in patients with left systolic heart failure. Secondary endpoints included exercise capacity assessed by 6-minute walk test. A total of 106 patients were randomized 1:1 to sildenafil (n=53) or placebo (n=53). Patients received sildenafil 25 mg twice a day or matching placebo for the first 2 weeks and 50 mg 3 times a week for the remainder of the trial. The placebo-corrected effect on mean blood pressure was 1.16 mm Hg (95% confidence interval, -1.6 to 5.1, P>.05), demonstrating that sildenafil did not decrease mean blood pressure. Compared with placebo, sildenafil increased the 6-minute walk test by a nonsignificant treatment effect of 14 m (P=.67). Adverse effects occurred in a comparable proportion of patients taking sildenafil and placebo, and none of the patients needed to discontinue therapy. Sildenafil is well tolerated in left heart failure patients and does not decrease blood pressure. It can be safely added to standard heart failure therapy.
