Abstract
A selective fluorescence turn-on immunosensor for the specific detection of cardiac troponin I (cTnI), the potent biomarker for myocardial infarction diagnosis, was developed with a nano couple comprised of protein-stabilized gold nanocluster and gold nanoparticle. The red fluorescence of cTnI-specific antibody tagged bovine serum albumin stabilized gold nanoclusters was quenched with gold nanoparticles (AuNP) via the intensive interaction between amine and hydroxyl functionalities of BSA and AuNP. Through this, the adsorption of gold nanoclusters at the surface of AuNP, resulting in a core-satellite assembly, was assumed to quench the fluorescence emission. While in the presence of cTnI antigen, this gets disturbed due to the formation of immunocomplex between cTnI antigen and antibody, which restricts the close interaction between gold clusters and nanoparticles, thereby restoring quenched fluorescence. The enhancement in fluorescence signal is directly related to the concentration of cTnI, and this facilitates the selective detection of cTnI in the linear concentration range 0.7 to 10 ng/mL without any interference from other potentially interfering co-existing biomolecules. An appreciable limit of detection of 0.51 ng/mL and a limit of quantification of 0.917 ng/mL for cTnI is comparable to that of the previous report.

Abstract
The biomacromolecule silk fibroin (SF) may be constructed to promote biomimetic nucleation and nanostructures of inorganic nanomaterials, offering it a promising candidate for use in various biomimetic applications. We combined SF-NPs and ZIF-8-NPs to fabricate new drug vehicles that effectively release the drug. SF nanoparticles (SF-NPs) were assembled into quercetin (QCT), a myocardial drug added to fabricate QSF-NPs. By acting as a template for the ZIF-8 nucleation onto the surface, the QSF-NPs fabricated core-shell-structured nanocomposites (named QSF@Z-NCs) with ZIF-8 as the core-shell and the QSF-NPs. The biocompatibility analysis using the MTT assay revealed that the developed QCT, SF-NPs, and QSF@Z-NCs are not harmful to cardiac myoblast (H9C2) cells. The in vivo model demonstrated that H9C2 cells encouraged cardiomyocyte fibre regeneration in myocardial infarction rats. We fabricated a brand-new technique using H9C2 cells and QSF@Z-NCs that might encourage the healing processes in myocardial ischemia cells. This study's results demonstrate that it successfully treats myocardial injury.

Abstract
The stress management program is not considered as a part of routine cardiac rehabilitation due to the lack of consensus and inconsistencies in the studies detailing the relation between stress and coronary artery disease. The current meta-analysis is intended to determine the effectiveness of stress management in cardiac rehabilitation. The published literature studies until December 2020 were extracted from various databases and eligible studies were selected based on the inclusion and exclusion criteria. Quality assessment of the selected studies was carried out using Jadad. The literature search of various databases yielded 154 studies and 9 were selected based on the inclusion/exclusion criteria. On the Jadad scale, 6 studies obtained a score of 3, whereas the remaining studies obtained a score of 2. Funnel plot findings reported no publication bias. The result of the meta-analysis showed a persistent improvement in Beck depression inventory-2, hospital anxiety scale and hospital depression scale in subjects who had undergone various stress management interventions. The meta-analysis corroborates the benefits of stress management training in cardiac rehabilitation and underscores the need to adopt a stress management program in routine cardiac care.

Abstract
Heart failure following myocardial infarction (MI), the primary cause of mortality worldwide, is the consequence of cardiomyocyte death or dysfunction. Clinical efforts involving the delivery of growth factors (GFs) and stem cells with the aim of regenerating cardiomyocytes for the recovery of structural and functional integrity have largely failed to deliver, mainly due to short half-lives and rapid clearance in in vivo environments. In this work, we selected and genetically fused four biofunctional peptides possessing angiogenic potential, originating from extracellular matrix proteins and GFs, to bioengineered mussel adhesive protein (MAP). We found that MAPs fused with vascular endothelial growth factor (VEGF)-derived peptide and fibronectin-derived RGD peptide significantly promoted the proliferation and migration of endothelial cells in vitro. Based on these characteristics, we fabricated advanced double-layered adhesive microneedle bandages (DL-AMNBs) consisting of a biofunctional MAP-based root and a regenerated silk fibroin (SF)-based tip, allowing homogeneous distribution of the regenerative factor via swellable microneedles. Our developed DL-AMNB system clearly demonstrated better preservation of cardiac muscle and regenerative effects on heart remodeling in a rat MI model, which might be attributed to the prolonged retention of therapeutic peptides as well as secure adhesion between the patch and host myocardium by MAP-inherent strong underwater adhesiveness.

Abstract
BACKGROUND There are no data available regarding the association of dietary diabetes risk reduction score (DDRRS) and risk of cardiovascular disease (CVD) worldwide. We aimed to investigate the association of the DDRRS with the risk of CVD outcomes in a prospective population-based study. METHOD Individuals without CVD (n=2,195) were recruited from participants of the Tehran Lipid and Glucose Study (2006-2008) and followed for a mean of 6.7 years. The DDRRS was determined on the basis of eight components using a validated 168-item food frequency questionnaire. Cox proportional hazard regression models, adjusted for potential confounders, were used to estimate the hazard ratios and 95% confidence interval (CI) of CVD across quartiles of DDRRS. RESULTS The mean ± standard deviation age of participants (44.8% male) was 38.8±13.0 years at baseline. Median DDRRS for all patients was 23 (intequartile range 20-26). During follow-up, 77 (3.5%) new cases of CVD were identified. After adjustment for confounding variables, including age, sex, body mass index, physical activity, smoking, energy intake, diabetes, and hypertension, no association was found between DDRRS and risk of CVD (odds ratio, 0.70; 95% CI, 0.36-1.37 [p-value for trend=0.351]). CONCLUSIONS The findings of this study showed that higher DDRRS is not associated with risk of CVD events.

Abstract
Myocardial infarction is caused by an interruption of coronary blood flow, leading to one of the main death causes worldwide. Current therapeutic approaches are palliative and not able to solve the loss of cardiac tissue. Cardiosphere derived cells (CDCs) reduce scarring, and increase viable myocardium, with safety and adequate biodistribution, but show a low rate engraftment and survival after implantation. In order to solve the low retention, we propose the encapsulation of CDCs within three-dimensional alginate-poly-L-lysine-alginate matrix as therapy for cardiac regeneration. In this work, we demonstrate the encapsulation of CDCs in alginate matrix, with no decrease in viability over a month, and showing the preservation of CDCs phenotype, differentiation potential, gene expression profile and growth factor release after encapsulation, moving a step forward to clinical translation of CDCs therapy in regeneration in heart failure.

Abstract
AIMS Patients who survive acute myocardial infarction (AMI) are at risk of being rehospitalized owing to the occurrence of acute decompensated heart failure (HF). However, the clinical characteristics of HF after AMI, especially the frequency of each HF subtype, are unclear. METHODS AND RESULTS We retrospectively studied 1055 patients with AMI. We excluded 257 patients, who were admitted >48 h after the onset of AMI, died during hospitalization or after discharge, and whose echocardiogram data at index hospitalization and follow-up data were missing. The remaining 798 patients (mean age: 66.5 ± 11.7 years) were investigated for a mean follow-up period of 4.9 years. All patients underwent emergency coronary angiography. The mean maximum creatine kinase levels were 2898 ± 2627 IU/L, and mean left ventricular ejection fraction (LVEF) was 58.9 ± 10.2%. Eighty-one patients (10.2%) were rehospitalized because of unexpected worsening of HF. Echocardiography data were available for 74 of the 81 patients during the acute phase of the second hospitalization, of which 30, 20, and 24 patients (41%, 27%, and 32%, respectively) were diagnosed as having HF with preserved LVEF (LVEF ≥ 50%), HF with mid-range LVEF (40% ≤ LVEF < 50%), and HF with reduced LVEF (LVEF < 40%), respectively. The ejection fraction during index hospitalization was 58.3 ± 9.7% in the HF with preserved LVEF group, 53.3 ± 10.2% in the HF with mid-range LVEF group, and 43.3 ± 10.5% in the HF with reduced LVEF group (P < 0.001). CONCLUSIONS The predominant subtypes of HF after AMI were HF with mid-range ejection fraction and preserved ejection fraction, or HF with non-reduced ejection fraction.

Abstract
BACKGROUND The usefulness of the combined assessment of HbA1c and plasma glucose (PG) in acute myocardial infarction (AMI) in non-diabetic patients remains unclear. PURPOSE In a large observational study, we aimed to identify the prognostic values of these biomarkers regarding one-year all-cause mortality in non-diabetic patients after AMI. METHODS From the "obseRvatoire des Infarctus de Côte d'Or" (RICO) survey database, we included all consecutive non-diabetic patients with AMI (n=6617) from May 2001 to December 2016. Exclusion criteria were: admission known or unknown diabetes, in-hospital death. The primary endpoint was all-cause one-year mortality. The secondary endpoints were: MACE, infarct size, LVEF<40% and GRACE risk score. Cut-off levels (high/low) were determined by ROC curve analysis for the prediction of one-year death (HbA1c 5.9% and PG 131mg/dL) to set up 4 groups: low HbA1c/low glucose (n=3158), low HbA1c/high glucose (n=1264), high HbA1c/low glucose (n=1378) and high HbA1c/high glucose (n=817). RESULTS Elevation of PG was associated with elevated rate of LVEF<40%, STEMI, anterior wall location, DFG<60mL/min/m2 and higher troponin Ic pic (all P<0.001); HbA1c>5.9% was associated with elevated rate of CRP>3mg/L (P<0.001); high HbA1c and high PG together were associated with higher rate of MACE (P<0.001). By multivariate logistic regression analysis, elevated admission PG remained a strong predictor of one-year all-cause [OR (95%CI): 1.64 (1.31-2.05)] mortality and cardiovascular mortality [OR (95%CI): 1.75 (1.33-2.31)], beyond GRACE score [OR (95%CI): 1.03 (1.03-1.04)], as well as elevated HbA1c [OR (95%CI): 1.43 (1.15-1.78) and OR (95%CI): 1.83 (1.39-2.41) respectively]. CONCLUSIONS Admission PG and HbA1c had strong independent predictive value regarding one-year all-cause mortality in our non-diabetic patients with AMI. These biomarkers could be useful to identify the most-at-risk patients after AMI in order to reduce residual risk in this target population.

Abstract
Background Heart failure (HF) is one of the most common causes of cardiovascular diseases in the world. Currently, the drugs used to treat HF in the clinic may cause serious side effects. Liguzinediol, 2, 5-dimethyl-3, 6-dimethyl-pyrazine, is a compound synthesized after the structural modification of ligustrazine (one active ingredient of Szechwan Lovage Rhizome). We aimed to observe the effects of liguzinediol on preventing HF and explore the related mechanisms. Methods The ligation of left anterior descending coronary artery was operated to established the myocardial infarction (MI) model in Sprague–Dawley rats. Cardiac functions were recorded by echocardiography and hemodynamics. The changes in the Renin–Angiotensin–Aldosterone System (RAAS), inflammation, and oxidative stress were detected by radioimmunoassay and Elisa kits. Western blot and real-time PCR were applied to determine the expressions of the TGF-β1/Smads pathway. Results Firstly, liguzinediol enhanced the systolic and diastolic functions of the heart in MI rats. Liguzinediol improved ventricular remodeling by reducing myocardial cell necrosis, as well as reducing collagen deposition and myocardial fibrosis. Then, liguzinediol suppressed the activation of RAAS, inhibited the synthesis of pro-inflammation factors, and reduced oxidative stress. In the end, liguzinediol also down-regulated the expressions of the TGF-β1/Smads pathway. Conclusions Liguzinediol could alleviate HF caused by MI in rats, and the protective effect was associated with the regulation of the TGF-β1/Smads pathway.![]()

Abstract
Cardiovascular diseases are the primary reason of mortality, among which myocardial infarction (MI) is the most dominant and prevalent. This study was considered to examine D-Limonene protective action against isoproterenol (ISO) induced MI. Wister male rats were dispersed into four groups. Normal and D-Limonene control group in which rats administered saline or D-Limonene. ISO control animals were administered saline for 21 days then challenged with ISO (85 mg/kg, subcutaneously) on 20th and 21st day for MI induction. D-Limonene pretreated group in which animals were pretreated with D-Limonene 50 mg/kg orally for 21 days then administered ISO on 20th and 21st day. MI prompted variations were assessed by myocardial infarction area determination, blood pressure (BP) alterations, cardiac injury biomarkers and inflammatory mediators measurements. For more depth investigation, both the apoptotic status was evaluated via measuring mRNA expression of Bcl-2 and Bax as well as mitogen-activated protein kinase-extracellular signal-regulated kinase (MAPK-ERK) signal transduction were investigated via Western blotting. MI group revealed significant infarcted area, blood pressure alterations, myocardial injury enzymes intensification together with inflammatory cytokines amplification. MI was associated with activation of MAPK-ERK signal pathway and apoptotic status within the myocardium. On the other hand, pretreated with D-Limonene demonstrated deterred infracted area, reduced myocardial enzymes, improved BP indices, lessened inflammatory levels. Furthermore, D-Limonene pretreatment caused a decline in MAPK proteins pathway and Bax relative mRNA expression, while intensifying Bcl-2 mRNA expression promoting that D-Limonene may constrain MI induced myocardial apoptosis. D-Limonene mitigated MI injury through MAPK/NF-κB pathway inhibition and anti-apoptotic effect.

Abstract
BACKGROUND Myocarditis refers to a variety of myocardial inflammatory lesions. A variety of factors such as infection and physical and chemical factors can cause myocarditis. Depending on the severity of myocardial damage, myocarditis patients can manifest heart failure, cardiogenic shock, and even sudden death. Here we present a case of viral myocarditis that mimicked acute coronary syndrome.
CASE SUMMARY A middle-aged male patient presented with chest pain and elevated troponin I after a flu-like infection. This patient had a history of hypertension and a habit of alcohol and tobacco use. Electrocardiography showed typical changes in acute myocardial infarction, with the T-wave increasing. Coronary angiogram revealed no stenosis. Cardiac magnetic resonance imaging revealed edema of the middle and apical septal and apical anterior walls on T2-weighted images and the T1 mapping. Late gadolinium enhancement of the middle and apical septal and apical anterior walls could be found. Rubella virus immunoglobulin G and immunoglobulin M antibodies were abnormally elevated. The patient was given antiviral and antibiotic treatments, and serum biomarkers and electrocardiograph returned to normal after 5 d of treatment. After one-year follow-up, the patient showed no symptoms, and cardiac magnetic resonance showed that myocardial thickness was significantly thinner than before, and fibrosis was less than before.
CONCLUSION This case illustrates the utility of cardiac magnetic resonance for diagnosis of infarction-like myocarditis when the angiogram is normal.

Abstract
Wogonin, one of the main active ingredients of Scutellaria radix, is a kind of flavonoid compound. In the present study, we report that wogonin nanoparticles (Wog np) protect Isoproterenol (ISO) induced Myocardial Infarction (MI) rats. Nanoparticles of sizes less than 200 nm with spherical shape were prepared using Polylactic-co-glycolic acid (PLGA) and Polyvinyl alcohol (PVA) respectively as polymer and stabilizer. Male Wistar rats were divided into 4 groups. Group 1 as a control group administered with physiological saline solution with 0.5 % carboxymethylcellulose (1 mL/day). Group 2 served as toxic group; rats received physiological saline solution with 0.5 % carboxymethylcellulose (1 mL/day) orally for 21 days Groups 3 and 4 received Wog np (25 and 50 mg/kg/day) orally for 21 days and on the 20th and 21 st days group 2, 3, and 4 were administered with ISO (85 mg/kg) through s.c. route at 24 h interval. pre-treatment with Wog np (25 and 50 mg/kg) could significantly reduce the cardiac infarct size, serum cardiac markers, lipid peroxidation product (MDA) and inflammatory markers as well as markedly upregulated the protein expression of nuclear factor erythroid 2-related factor (Nrf2)and heme oxygenase-1 (HO-1) to confer its strong cardioprotective activity against ISO induced myocardial damage.

Abstract
Introduction Structural and functional changes that occur post myocardial infraction (MI) lead to the syndrome of heart failure (HF). However, their pathogenesis is poorly understood. Recently, alteration of the intestinal microbiota (dysbiosis) has emerged as a new candidate that may be correlated with risk of HF development. We hypothesized that selective gut modulation by probiotic administration may improve metabolic dysfunction and attenuate cardiac remodeling (CR) in MI subjects. Methods /Design: This article is presented in two sections: First, we provided a review of recent findings related to gut microbiota and CR and their association with probiotic supplementation. Secondly, we will conduct a randomized double-blinded controlled clinical trial in 46 Iranian patients with MI after successful percutaneous coronary intervention (PCI). The participants (age: ≥ 30 years; ejection fraction (EF) greater than 30) will be selected by a simple random sampling method and will be assigned to 3 months of 1.6* 109 CFU probiotic (Lactobacillus rhamnosus), or placebo groups (maltodextrin). The primary outcome is development of CR. The secondary outcomes measures include gut microbiota profile, biochemical variables and the safety of the probiotics supplementation. Also, echocardiography will be measured at baseline and following treatment. The data will be compared within and between groups using appropriate statistical methods. Discussion The results of this trial will provide evidence about the efficacy and safety of gut microbiota manipulation by probiotics in post-MI cardiac remodeling prevention. Ethical issues Present study protocol was approved by the regional committee of ethics in international branch of Tabriz University of Medical sciences (TBZMED) as a thesis proposal for PhD degree in Nutrition Sciences (IR.TBZMED.REC.1397.184). Trial registration The Clinical trial was registered in the Iranian Registry of Clinical Trials (IRCT20121028011288N15).

Abstract
OBJECTIVE An extract of Costus speciosus (CSE), a herb widely used in folk medicine, was evaluated for its antioxidant, antihyperlipidemic and ameliorating effects on histopathological changes in atherogenic rabbits. METHODS Twenty-four male rabbits (Oryctolagus cuniculus) were divided into 4 groups. Three groups were fed a diet containing 3% saturated fat and 1.3% cholesterol for 40 d. One of these was sacrificed on the 40th day and was called the pathogenic (P) group; the other two groups received treatment for another 30 d as follows: one received 0.8 g/(kg·d) of CSE and the other was given 0.01 g/(kg·d) of simvastatin. The normal group was sacrificed on the 70th day and used as a control. RESULTS CSE showed radical-scavenging ability. Administration of CSE for a 30-day period resulted in a significant decrease in total cholesterol, triacylglycerol, low-density lipoprotein and aspartate aminotransferase compared to the P group, while levels of hemoglobin, packed corpuscular volume and red blood cells were elevated. With respect to studies performed on the heart, a decrease in malondialdehyde and an increase in reduced glutathione were noted. Total protein increased in the liver, heart and aorta after treatment with CSE and also a marked improvement in histopathological parameters was demonstrated. CONCLUSION The present findings indicate that the C. speciosus rhizome possesses antiatherogenic and antioxidant properties which may provide protective effects against oxidative stress in atherosclerotic rabbits.

Abstract
BACKGROUND Few studies describe recent changes in the incidence, treatment and outcome of successfully resuscitated STEMI patients after out-of-hospital cardiac arrest (OHCA) compared with non-OHCA STEMI patients. OBJECTIVE To examine temporal trends in the incidence, therapeutic management, most serious complications, mortality rate and outcome of OHCA patients fulfilling criteria of STEMI compared with a reference group of STEMI patients without OHCA. METHODS Analysis of registry data (AMIS Plus Registry) among STEMI patients both with and without OHCA between 1997 and 2017. RESULTS Among 31,650 patients with STEMI, 6.8% were successfully resuscitated prior to hospital admission. Increasing incidences of hospital-admitted patients following successful out-of-hospital CPR were observed (4.5% in 1999 vs. 8.6% in 2017). OHCA STEMI patients were at higher clinical risk at presentation (36.1% vs. 2.7%; p < 0.001 with cardiogenic shock) despite a shorter time span from the onset of symptoms to hospitalization (195 min vs. 107 min; p < 0.001) and a lower prevalence of cardiovascular risk factors except smoking. More PCIs were performed in STEMI patients with OHCA (78.9% vs. 74.5% for non-OHCA patients; p < 0.001). However, over time PCI became the preferred primary intervention irrespective of the OHCA status of STEMI patients. For STEMI patients without OHCA, there was a significant correlation between PCI and time periods on in-hospital mortality (p < 0.001), which was p = 0.002 when adjusted for age and gender. For STEMI patients with OHCA, the interaction between PCI and time was unadjusted p = 0.395 and p = 0.438 when adjusted for age and gender.

Abstract
BACKGROUND/AIMS Cardiac fibrosis is a pathological change leading to cardiac remodeling during the progression of myocardial ischemic diseases, and its therapeutic strategy remains to be explored. S100A4, a calcium-binding protein, participates in fibrotic diseases with an unclear mechanism. This study aimed to investigate the role of S100A4 in cardiac fibrosis. METHODS Cardiac fibroblasts from neonatal C57BL/6 mouse hearts were isolated and cultured. Myocardial infarction was induced by ligating the left anterior descending coronary artery (LAD). The ligation was not performed in the sham group. A volume of 5×105pfu/g adenovirus or 5 µM/g ICG-001 was intramyocardially injected into five parts bordering the infarction zone or normal region. We used Western blotting, quantitative RT-PCR, immunofluorescence, immunohistochemistry and Masson's trichrome staining to explore the function of S100A4. RESULTS We found significant increases of S100A4 level and cardiac fibrosis markers, and β-catenin signaling activation in vitro and in vivo. In addition, knockdown of S100A4 significantly reduced cardiac fibrosis and β-catenin levels. Moreover, the expression of S100A4 decreased after ICG-001 inhibited β-catenin signal pathway. CONCLUSION Downregulation of S100A4 alleviates cardiac fibrosis via Wnt/β -catenin pathway in mice. S100A4 may be a therapeutic target of cardiac fibrosis.

Abstract
Prior studies identified the incremental value of non-invasive imaging by CT-angiogram (CTA) to detect high-risk coronary atherosclerotic plaques. Due to their superficial locations, larger calibers and motion-free imaging, the carotid arteries provide the best anatomic access for the non-invasive characterization of atherosclerotic plaques. We aim to assess the ability of predicting obstructive coronary artery disease (CAD) or acute myocardial infarction (MI) based on high-risk carotid plaque features identified by CTA. We retrospectively examined carotid CTAs of 492 patients that presented with acute stroke to characterize the atherosclerotic plaques of the carotid arteries and examined development of acute MI and obstructive CAD within 12-months. Carotid lesions were defined in terms of calcifications (large or speckled), presence of low-attenuation plaques, positive remodeling, and presence of napkin ring sign. Adjusted relative risks were calculated for each plaque features. Patients with speckled (<3 mm) calcifications and/or larger calcifications on CTA had a higher risk of developing an MI and/or obstructive CAD within 1 year compared to patients without (adjusted RR of 7.51, 95%CI 1.26-73.42, P = 0.001). Patients with low-attenuation plaques on CTA had a higher risk of developing an MI and/or obstructive CAD within 1 year than patients without (adjusted RR of 2.73, 95%CI 1.19-8.50, P = 0.021). Presence of carotid calcifications and low-attenuation plaques also portended higher sensitivity (100 and 79.17%, respectively) for the development of acute MI. Presence of carotid calcifications and low-attenuation plaques can predict the risk of developing acute MI and/or obstructive CAD within 12-months. Given their high sensitivity, their absence can reliably exclude 12-month events.

Abstract
Myocardial infarction (MI) remains the most frequent cardiovascular disease with high mortality. Recently, methane has been shown protective effects on small intestinal ischemia-reperfusion injury. We hypothesized that methane-rich saline (MS) could protect the myocardium again MI via its anti-oxidative, anti-apoptotic and anti-inflammatory effects. In experiment 1, tetrazolium chloride staining and detection of myocardial enzymes and oxidative and inflammatory parameters were performed at 12h after MI to determine the optimal dose at which intraperitoneal MS exerted the best protective effects on MI. In experiment 2, rats were treated with 10 ml/kg MS. Myocyte apoptosis was detected 72 h after MI, and cardiac function and myocardial remodeling were evaluated 4 weeks after MI. Results showed different dose of MS reduced infarct area, decreased myocardial enzymes, inhibited inflammation and oxidative stress following MI. The optimal dose of MS was 10 mg/kg. Moreover, treatment with 10mg/kg MS for 3 days significantly reduced myocyte apoptosis, improved cardiac function and inhibited myocardial remodeling (reduced anterior wall thickness, attenuated myocyte hypertrophy, and decreased myocardial collagen). MS protects the myocardium of MI rats via its anti-oxidative, anti-inflammatory, anti-apoptotic and anti-remodeling activities. Thus, MS provides a novel and promising strategy for the treatment of ischemic heart diseases.
