    Abstract Background: This study investigated the clinical outcomes at the minimum and maximum levels of hematocrit (HCT) during cardiopulmonary bypass (CPB) in low-risk patients undergoing coronary artery bypass graft (CABG) surgery.
    Materials and methods: In this cross-sectional study, 85 patients who underwent CABG with an ejection fraction of greater than 35% were selected. Based on the HCT range during CPB, patients were divided into two groups: minimum HCT: HCT = 16-18% and maximum HCT: HCT = 25-27%. Then the operation outcomes, amount of drainage, and transfusion were recorded and compared between these groups.
    Results: In the middle tube 8 h after surgery and left tube 24 h after surgery, the amount of drainage in the minimum HCT group with mean of 71.00 ± 130.9 and 60.65 ± 71.23, respectively, was significantly lower than the maximum HCT group with mean of 101.5 ± 246.50 and 123.76 ± 93.17, respectively (
    Conclusion: According to the results of this study, patients undergoing CABG surgery with maximum HCT level versus minimum HCT level during CPB, need more packed cells and fresh frozen plasma products transfusion, which will be associated with the complication of cognitive impairment.

    Abstract Heart failure (HF) is a pervasive clinical challenge characterized by compromised cardiac function and reduced quality of life. The kinin-kallikrein system (KSS), a multifaceted peptide cascade, has garnered substantial attention due to its potential role in HF. Through activation of B1 and/or B2 receptors and downstream signaling, kinins modulate various physiological processes, including inflammation, coagulation, pain, blood pressure control, and vascular permeability. Notably, aberrations in KKS components have been linked to HF risk. The elevation of vasodilatory bradykinin (BK) due to kallikrein activity reduces preload and afterload, while concurrently fostering sodium reabsorption inhibition. However, kallikrein's conversion of prorenin to renin leads to angiotensinsII upregulation, resulting in vasoconstriction and fluid retention, alongside increased immune cell activity that fuels inflammation and cardiac remodeling. Importantly, prolonged KKS activation resulting from volume overload and tissue stretch contributes to cardiac collagen loss. The conventional renin-angiotensin-aldosterone system (RAAS) inhibitors used in HF management may inadvertently intensify KKS activity, exacerbating collagen depletion and cardiac remodeling. It is crucial to balance the KKS's role in acute cardiac damage, which may temporarily enhance function and metabolic parameters against its detrimental long-term effects. Thus, KKS blockade emerges as a promising strategy to impede HF progression. By attenuating the link between immune system function and tissue damage, KKS inhibition can potentially reduce cardiac remodeling and alleviate HF symptoms. However, the nuanced roles of BK in various acute conditions necessitate further investigation into the sustained benefits of kallikrein inhibitors in patients with chronic HF.

    Abstract Owing to the augmented perception of heart failure (HF) pathophysiology, management of the affected patients has been improved dramatically; as with the identification of the inflammatory background of HF, new avenues of HF prognosis research have been opened up. In this regard, relative values of hematologic indices were demonstrated by a growing body of evidence to successfully predict HF outcomes. Cost-effectiveness, accessibility, and easy obtainability of these relative values make them a precious option for the determination of HF prognosis; particularly in low-income developing countries. In this short review, we aimed to present the current literature on the predictability of these hematologic parameters for HF outcomes.

    Abstract Background: Although intra-cardiac shocks are a lifesaving approach in patients with systolic heart failure (HF), the probable effective factors related to shock occurrence are less frequently recognized. We designed this study to assess the factors associated with inappropriate or appropriate implantable cardioverter-defibrillator (ICD) shocks in patients with non-ischemic cardiomyopathy (NICM).
    Methods: Ninety-nine patients with NICM who implanted ICD were enrolled from March 2018 to September 2019 and followed up with a three-month interval for up to one year. Shock therapy was defined as either appropriate or inappropriate shock. The odds ratio (OR) of inappropriate shock occurrence was calculated with crude and different adjusted models.
    Results: The mean age of the population at baseline was 51.9 ± 15.4 years (men: 71%). Baseline data revealed that patients with inappropriate shocks had higher heart rates (HR), worse New York Heart Association (NYHA) class, and anti-tachycardia pacing (ATP) as well as higher percentages of amiodarone usage compared to groups with appropriate or no shock [HR: 96.8 ± 27.8 vs. 79.8 ± 12.1 vs. 76.2 ± 17.6 beats per minute (bpm), P = 0.014; NYHA class IV: 85.7% vs. 74.1% vs. 63.4%, P = 0.041; ATP: 37.5% vs. 29% vs. 5%, P = 0.010; amiodarone usage: 37.5% vs. 25.8% vs. 5%, P = 0.23, respectively]. Further multiple-adjusted OR did not reveal any significant independent association between the aforementioned variables and inappropriate shock incidence.
    Conclusion: This study indicates no significant independent predisposing factor in the occurrence of inappropriate shocks among patients with NICM. Other studies are required in this regard.

    Abstract Background: Clinical Practice Guidelines (CPGs) have been recommended to manage palliative care and take the best treatment measures and decisions. This study aimed to adapt the interdisciplinary CPG to provide palliative care for patients with Heart Failure (HF) in Iran based on the ADAPTE method.
    Materials and methods: Guideline databases and websites were systematically searched up to April 2021 to determine appropriate publications related to the study topic. Followed by assessing the quality of the selected guidelines via the Appraisal of Guidelines for Research & Evaluation Instrument (AGREE II), those with appropriate standard scores were selected to be used in designing the initial draft of the adapted guideline. The developed draft contained 130 recommendations and was evaluated by a panel of interdisciplinary experts in terms of its relatedness, comprehensibility, usefulness, and feasibility in two phases of Delphi.
    Results: In the first phase of Delphi, the adapted guideline was derived from five guidelines and evaluated by 27 interdisciplinary pundits working in the universities of Tehran, Isfahan, and Yazd cities. After the assessment in Delphi Phase 2, four recommendation categories were removed because they did not receive the required scores. Finally, 126 recommendation items were included in the developed guideline, which were classified into three main categories of palliative care features, essentials, and organization.
    Conclusions: In the present study, an interprofessional guideline was designed to enhance palliative care information and practice in patients with HF. This guideline can be administered as a valid tool for interprofessional team members to provide palliative care to patients with HF.

    Abstract MicroRNAs (miRs, miRNAs) are known to have a part in various human illnesses, such as those related to the heart. One particular miRNA, miR-155, has been extensively studied and has been found to be involved in hematopoietic lineage differentiation, immunity, viral infections, inflammation, as well as vascular remodeling. These processes have all been connected to cardiovascular diseases, including heart failure, diabetic heart disease, coronary artery disease, and abdominal aortic aneurysm. The impacts of miR-155 depend on the type of cell it is acting on and the specific target genes involved, resulting in different mechanisms of disease. Although, the exact part of miR-155 in cardiovascular illnesses is yet not fully comprehended, as some studies have shown it to promote the development of atherosclerosis while others have shown it to prevent it. As a result, to comprehend the underlying processes of miR-155 in cardiovascular disorders, further thorough study is required. It has been discovered that exosomes that could be absorbed by adjacent or distant cells, control post-transcriptional regulation of gene expression by focusing on mRNA. Exosomal miRNAs have been found to have a range of functions, including participating in inflammatory reactions, cell movement, growth, death, autophagy, as well as epithelial-mesenchymal transition. An increasing amount of research indicates that exosomal miRNAs are important for cardiovascular health and have a major role in the development of a number of cardiovascular disorders, including pulmonary hypertension, atherosclerosis, acute coronary syndrome, heart failure, and myocardial ischemia-reperfusion injury. Herein the role of miR-155 and its exosomal form in heart diseases are summarized.

    Abstract Objectives: While the principles for developing clinical practice guidelines (CPGs) are well established, the quality of published guidelines is very diverse. The present study was conducted to evaluate the quality of existing CPGs in palliative care for heart failure patients.
    Material and methods: The study was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-analyses. A systematic search was conducted in the Excerpta Medica Database, MEDLINE/PubMed, CINAHL databases and Guideline internet sites: National Institute for Clinical Excellence, National Guideline Clearinghouse, Scottish Intercollegiate Guidelines Network, Guidelines International Network and National Health and Medical Research Council for CPGs published through April 2021. Criteria for including CPGs were: Containing palliative measures for patients with heart failure over 18 years old and preferably interprofessional guidelines that focus on only one dimension of palliative care or focus on diagnosis, definition and treatment were excluded from the study. After initial screening, five appraisers rated the quality of the final selection of CPGs using the Appraisal of Guidelines for Research and Evaluation, 2
    Results: From 1501 records, seven guidelines were selected for analysis. The 'scope and purpose' and 'clarity of presentation' domains obtained the highest mean and 'rigor of development' and 'applicability' domains obtained the lowest mean scores. Three categories of recommendations were: (1) Strongly recommended (guidelines 1, 3, 6 and 7); (2) recommended with modifications (guideline 2) and (3) not recommended (guidelines 4 and 5).
    Conclusion: Clinical guidelines for palliative care in patients with heart failure were of moderate-to-high quality, with the main deficiencies occurring in the rigor of development and applicability domains. The results inform clinicians and guideline developers of the strengths and weaknesses of each CPG. To improve the quality of palliative care CPGs in the future, it is recommended that developers pay detailed attention to all domains of the AGREE II criteria.

    Abstract Background: Introduction of simple bedside tools for assessing patients' condition in different settings improves triaging. However, these indices are less frequently used in heart failure. This study aims to evaluate the utility of shock index, age shock index, modified shock index, and age-modified shock index in the prediction of in-hospital mortality in acute decompensated heart failure individuals.
    Methods: We conducted this retrospective study on 3652 acute decompensated heart failure individuals in the context of Persian Registry of Cardiovascular Disease/heart failure. Shock index, age shock index, modified shock index, and age-modified shock index were assessed during admission. Receiver operating characteristic curve was used to define the optimum cut-off point. Odds ratio models were used for investigating the association of in-hospital mortality according to each specified cut-off value.
    Results: Mean age was 70.12 ± 12.56 years (males: 62.6%). Optimum cut-off point for shock index, age shock index, modified shock index, and age-modified shock index were set to be 0.71 (sensitivity: 63%, specificity: 60%), 50.5 (sensitivity: 65%, specificity: 60%), 0.94 (sensitivity: 60%, specificity: 60%), and 66.7 (sensitivity: 62%, specificity: 60%), respectively. Participants with higher shock index derivatives in all domains had significantly higher likelihood of death. Compared to those with shock index, age shock index, modified shock index, and age-modified shock index values of less than cut-off points, adjusted model revealed patients with higher values had 2.59 (95% CI: 1.94-3.46, P<.001), 2.61 (95% CI: 1.95-3.48, P <.001), 2.14 (95% CI: 1.61-2.84, P <.001), and 2.28 (95% CI: 1.72- 3.03, P <.001) times increase in-hospital death risk, respectively.
    Conclusions: Shock index, age shock index, modified shock index, and age-modified shock index are simple bedside tools to reliably predict in-hospital mortality in acute decompensated heart failure patients to better prioritize high-risk subjects.

    Abstract Method: This study is performed in the context of the Persian Registry of Cardiovascular Disease/Heart Failure (PROVE/HF). We included all patients admitted with ADHF regardless of the etiology of heart failure (HF). LOS was classified in tertiles (<4 days, >4 and <6 days, and >6 days). Our outcomes were 30-day all-cause mortality and rehospitalization. Baseline characteristics and outcomes are reported according to the tertiles of LOS. A binary logistic regression and cox regression analysis were performed to evaluate the association between LOS and rehospitalization and death, respectively.
    Results: Between April 2019 and March 2020, 385 patients with ADHF were registered in our study. The mean length of hospitalization was 6.35 ± 5.46 days, varying from a minimum of 0 days to a maximum of 47 days. One hundred patients had a hospital stay lower than 4 days; 151 individuals had an intermediate LOS (4-6 days); and 134 were hospitalized for more than 6 days. Our analysis indicated no association between LOS and 30-day rehospitalization and death in multivariable or univariable models.
    Conclusion: This study found no association between LOS and rehospitalization or death in patients admitted with ADHF; however, further investigations are warranted.

    Abstract This study aims to evaluate the effect of levothyroxine therapy on blood pressure (BP) in patients with subclinical hypothyroidism (SCH). Were searched Six databases, and randomized controlled trials (RCT) and prospective cohort studies evaluating the effect of levothyroxine therapy on BP in patients with SCH were included. 37 articles (9 RCTs and 28 prospective cohorts) were included in this meta-analysis. Pooled analysis of RCT studies was insignificant; however, pooled analysis of 28 prospective cohort studies showed a significant difference before and after the therapy, reducing both systolic blood pressure (SBP) and diastolic blood pressure (DBP) (MD=-4.02 [-6.45, -4.58] and MD=-2.13 [-3.69, -0.56], both P-values<0.05). Levothyroxine therapy can play a role in lowering BP in patients with SCH. However, this effect is more observed in Caucasians, SCH patients with higher initial TSH followed by more remarkable TSH change to normal levels, and SCH patients with hypertension.
