RESUMO

BACKGROUND: Patients with acute myocardial infarction are at greater risk for chronic heart failure and mortality. Currently, there is limited evidence supporting the beneficial effects of sodium-glucose cotransporter-2 inhibitors on cardiovascular outcomes in non-diabetic patients with reduced left ventricular ejection fraction following acute myocardial infarction. Furthermore, the clinical effects of the combination of standard-dose sodium-glucose cotransporter-2 inhibitors with colchicine and high-dose sodium-glucose cotransporter-2 inhibitors in this setting have not been evaluated yet. METHODS: A prospective, double-blinded, parallel-group, placebo control randomized trial will be carried out at Shahid Madani Heart Center, the largest teaching referral hospital for cardiovascular diseases, affiliated with Tabriz University of Medical Sciences. A total of 105 patients with reduced left ventricular ejection fraction (≤ 40%) following the first episode of ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention with stent insertion will be randomized 1:1:1 to receive empagliflozin 10 mg daily, a combination of empagliflozin 10 mg daily and colchicine 0.5 mg twice daily, or empagliflozin 25 mg daily for 12 weeks. The primary outcomes are changes in the New York Heart Association functional classification and high-sensitivity C-reactive protein from the randomization through week 4 and week 12. DISCUSSION: The present study will be the first trial to evaluate the efficacy and safety of early treatment with the combination of standard-dose empagliflozin and colchicine as well as high-dose empagliflozin in non-diabetic patients with reduced left ventricular ejection fraction following ST-elevation myocardial infarction. The results of this research will represent a significant step forward in the treatment of patients with acute myocardial infarction. TRIAL REGISTRATION: Clinical trial ID: IRCT20111206008307N39. Registration date: 27 October 2022.

RESUMO

Despite the growing body of evidence regarding the beneficial cardiovascular effects of sodium-glucose cotransporter-2 (SGLT2) inhibitors, clinical data in individuals without diabetes, heart failure (HF), and/or chronic kidney disease (CKD) is limited. A systematic review of the literature was conducted in PubMed, Scopus, Web of Science, Cochrane Library, and Google Scholar, from database inception until May 4, 2023, to explore new evidence of SGLT2 inhibitors' cardiovascular benefits in individuals without diabetes, HF, and/or CKD. A total of 1156 individuals from 14 studies (13 randomized controlled trials and 1 nonrandomized study) were included. The results showed the benefits of SGLT2 inhibitors on blood pressure, weight, and body mass index in this population with an acceptable safety profile. The current evidence supports the potential role of SGLT2 inhibitors as primary prevention in individuals without diabetes, HF, and/or CKD. This review may shed light on the use of SGLT2 inhibitors in conditions such as stage A HF and metabolic syndrome. The literature trend is going toward uncovering SGLT2 inhibitors' role in stage B HF, different types of myocardial infarction, and cardiac arrhythmias.

RESUMO

Currently, the world is recovering from the shock of the coronavirus disease 2019 (COVID-19) pandemic; however, this situation is still fragile. Health authorities recommend administering COVID-19 vaccines as the safest and most reliable tool for eliminating COVID-19. Subsequent to the extensive administration of the COVID-19 vaccines, a series of cardiovascular adverse effects have been reported. This comprehensive review aimed to provide an update on the etiology, pathophysiology, clinical features, and management of the cardiovascular adverse events associated with COVID-19 vaccines, including myocarditis, pericarditis, thrombosis with thrombocytopenia syndrome, myocardial infarction, cardiac arrhythmias, hypertension, and stress-induced cardiomyopathy. The benefits of COVID-19 vaccination far outweigh the reported adverse events. It would be clinically important to provide diagnostic scoring systems to differentiate COVID-19-related cardiovascular adverse events from other causes and develop therapeutic approaches for their management. Further evaluation of cardiovascular adverse events of the COVID-19 vaccines is crucial for implementing vaccination programs and developing safer and more reliable vaccines.

RESUMO

The pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global crisis with a growing number of mortalities and morbidities worldwide. Despite performing numerous researches, there are still considerable unrevealed details regarding the long-term complications and post-infection immunity of the coronavirus disease 2019 (COVID-19). Based on pathophysiological features, SARS-CoV-2 may act similarly as an oncovirus in the lung. This letter summarized three possible oncogenic mechanisms of SARS-CoV-2 that may be associated with lung cancer development.

RESUMO

This study aimed to detect the defects of the current methods used to monitor unfractionated heparin (UFH) anticoagulant effect and find possible assistive parameters for activated partial thromboplastin time (aPTT) test to improve treatment performance. The required information was gathered from patients' case records, treatment charts and laboratory reports. Kendall's tau correlation coefficient was calculated for analysing the relationship between variables. The partial least squares (PLS) and the stepwise multiple regression were operated, and the area under the receiver operating characteristic curve (AUC) and the r-squared (r2) were used to show the analytical ability of the models, respectively. Overall, 102 UFH-receiving ischemic heart disease patients participated in this study. The aPTT value varied from 30 to 95 s (mean ±â€ŠSD = 44 ±â€Š14). Therapeutic aPTT values were observed in 15% of hospitalization days. The aPTT value showed statistically significant correlations with mean UFH infusion (U/kg/h), age, prothrombin time (PT), smoking, international normalized ratio, haemoglobin (Hgb) and blood triglyceride level. Triglyceride level and PT were efficacious predictors of aPTT value (P < 0.001, r2 = 0.336). Moreover, blood urea nitrogen (BUN) and blood creatinine (Cr) levels were the best predictors for mortality. The mean BUN/Cr ratio was 18 ±â€Š5 and 25 ±â€Š12 in nonexpired and expired subjects, respectively. If calibrated institution-specific therapeutic aPTT ranges and updated weight-based UFH nomograms get employed, aPTT test, along with the BUN/Cr ratio and Hgb level, as assistive parameters for predicting haemorrhagic incidents, would be near ideal monitoring method in UFH-receiving patients.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has become a global health crisis. Considering the recent food and drug administration (FDA) approval of remdesivir as the first officially approved agent for COVID-19 treatment, we performed this systematic review and meta-analysis to evaluate the efficacy and safety of remdesivir administration in COVID-19 patients. A systematic literature search was done through MEDLINE, Google Scholar, Web of Science, Scopus, Science Direct, Cochrane Library, medRxiv, and bioRxiv from their inception to December 22nd, 2020. Five randomized controlled trials (RCTs) and five non-randomized studies of intervention (NRSI) were entered into the meta-analysis. The results showed that remdesivir administration was associated with a significant improvement in the 28-day recovery (RR = 1.09, 95%CI, 1.04-1.15), low flow oxygen support through days one to 14 (RR = 2.88, 95%CI, 1.80-4.60), and invasive mechanical ventilation or extracorporeal membrane oxygenation requirement through days 14-28 of the follow-up time (RR = 5.34, 95%CI, 2.37-12.05). The risk of experiencing serious adverse drug reactions (ADRs) was significantly lower (RR = 0.75, 95%CI, 0.63-0.90) in the remdesivir group than the comparison/control group. The pooled median difference of the time to clinical improvement was 2.99 (95%CI = 2.71-3.28), which did not remain significant during the sensitivity analysis. The clinical output comparison of the 5-day and 10-day remdesivir courses revealed that the 5-day regimen might provide similar benefits while causing fewer serious ADRs than 10-day. The current meta-analysis provided an updated evaluation of scientific evidence on the use of remdesivir in COVID-19 patients. Performing adequate well-designed RCTs are needed to show more accurate results.

RESUMO

Introduction: The coronavirus disease 2019 (COVID-19) pandemic, caused by a newly discovered coronavirus (severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2), continues to spread all around the world. Despite the emergency of COVID-19 worldwide, remdesivir is the only treatment that has been recently approved to treat the diseases, and other effective therapies are still lacking. SARS-CoV-2 may cause severe illness in 20% of patients. Based on available data, there is an association between interleukin-6 (IL-6) and severe COVID-19. Sarilumab is a fully human immunoglobulin G1 monoclonal antibody binding to both membrane-bound and soluble IL-6 receptors with high affinity and has been considered for off-label use in the treatment of COVID-19.Areas covered: The present article reviews recently published literature focusing on the pathophysiology of COVID-19 induced cytokine storm, the potential therapeutic role, and important clinical issues of sarilumab in the treatment of COVID-19 patients.Expert opinion: The off-label treatment administration is unavoidable in the critical situation of the COVID-19 pandemic. Further efforts should be directed to determine mechanisms of SARS-CoV-2 induced immune dysregulation as well as indications of sarilumab in the patients with COVID-19 to minimize concerns regarding its off-label administration.
