Abstract Objectives Atrial remodeling is the main developmental cause of atrial arrhythmias (AA), which may induce atrial fibrillation, atrial flutter, atrial tachycardia, and frequent premature atrial beats in acute myocardial infarction (AMI) patients. Thrombospondin-1 (TSP-1) has been shown to play an important role in inflammatory and fibrotic processes, but its role in atrial arrhythmias is not well described. The purpose of this study was to investigate the role of TSP-1 in AMI patients with atrial arrhythmias. Methods A total of 219 patients with AMI who underwent percutaneous coronary intervention and with no previous arrhythmias were included. TSP-1 were analyzed in plasma samples. Patients were classified into 2 groups, namely, with and without AA during the acute phase of MI. Continuous electrocardiographic monitoring was used for AA diagnosis in hospital. Results Twenty-four patients developed AA. Patients with AA had higher TSP-1 levels (29.01 ± 25.87 μg/mL vs 18.36 ± 10.89 μg/mL, p < 0.001) than those without AA. AA patients also tended to be elderly (65.25 ± 9.98 years vs 57.47 ± 10.78 years, p < 0.001), had higher Hs-CRP (39.74 ± 43.50 mg/L vs 12.22 ± 19.25 mg/L, p < 0.001) and worse heart function. TSP-1 (OR 1.033; 95% CI 1.003–1.065, p = 0.034), Hs-CRP (OR 1.023; 95% CI 1.006–1.041, p = 0.008), age (OR 1.067; 95% CI 1.004–1.135, p = 0.038) and LVDd (OR 1.142; 95% CI 1.018–1.282, p = 0.024) emerged as independent risk factors for AA in AMI patients. Conclusion TSP-1 is a potential novel indicator of atrial arrhythmias during AMI. Graphical abstract

Very late stent thrombosis (VLST) is a rare but serious complication following percutaneous coronary intervention (PCI). S100A8/A9 plays an important role in thrombosis through modulating the inflammatory response. This observational study aimed to reveal the association between S100A8/A9 and VLST. Continuous blood samples were collected from patients at both the time of index PCI for acute myocardial infarction (AMI) and the time of PCI for VLST (VLST group) or follow-up coronary angiography (AMI group). In all, 56 patients were selected in each group from a cohort of 8476 patients and other 112 individuals who underwent health checkups (normal control [NC] group) were selected as controls. Serum levels of S100A8/A9 and high sensitivity C-reactive protein (hs-CRP) were tested and compared. The mean level of S100A8/A9 was 3754.4 ± 1688.9 ng/mL during index PCI and increased to 5517.8 ± 2650.9 ng/mL at the time of VLST; in the AMI group, S100A8/A9 level was 2434.9 ± 1243.4 ng/mL during index PCI and decreased to 1568.2 ± 772.1 ng/mL during follow-up, similar to that detected in the NC group (1618.2 ± 641.4 ng/mL). Of note, S100A8/A9 levels showed significant increases during VLST when compared to its own levels during index PCI, which was different from the changes of hs-CRP. Higher serum levels of S100A8/A9 are associated with the development of VLST.

Abstract BackgroundThe incidence of acute myocardial infarction is increasing each year. Percutaneous coronary intervention has become highly preferred for patients with acute myocardial infarction because it not traumatic and improves heart function. However, the mortality and disability rates are still high. For the first time, we used ivabradine in patients with acute anterior myocardial infarction. We expect that this new method will enhance heart function and clinical prognosis because of heart rate control, decreases in heart preload and improvements in left ventricular end-diastolic volume.Method and analysisThis is a prospective, randomized, controlled, open-label, multicenter and optimally designed clinical trial. A total of 500 patients with acute anterior myocardial infarction after Percutaneous coronary intervention(PCI)with early heart failure will be enrolled. Eligible subjects will be randomized at a 1:1 ratio to take the standard drug treatment or receive the standard drug treatment plus ivabradine. The primary outcome measure is left ventricular end-diastolic volume. Left ventricular ejection fraction, adverse cardiac events, and the Canadian angina pectoris score will be evaluated as secondary endpoints. Blood biochemical testing will be used as the safety endpoints. Ethics and dissemination The clinical research will be carried out in strict accordance with the relevant Chinese laws and regulations, the Declaration of Helsinki, and the ethical and scientific principles stipulated by the Chinese GCP. All participants will provide informed consent. The personal information of patients will be kept confidential. Findings from the trial will be disseminated through peer-reviewed journals and scientific conferences.ClinicalTrials.govID:ChiCTR2000032731,Registered8May,2020 http://www.chictr.org.cn/showproj.aspx?proj=53275 Trial Statusversion number: Protocol version 1.0., approved9 May,2020Trial ongoingStudy execute time: From 1 September 2020 to 31 Octomber 2022Recruiting time: From 8 May 2020 to 31 December 2022

Abstract Background Our previous study had found that the abundance of Lactobacillaceae in stool of acute coronary syndrome patients was significantly decreased. Experiments have confirmed that Lactobacillus has the effects of anti-inflammation, regulating blood lipids and improving cardiac injury after myocardial infarction. Purpose To explore the relationship between Lactobacillus and prognosis of acute myocardial infarction (AMI) patients treated by percutaneous coronary intervention (PCI) and its possible mechanism. Methods Patients with AMI who received emergency PCI from July 2017 to December 2018 in department of CCU were enrolled.Stool and blood samples were collected from all patients. The fecal 16S rDNA gene sequencing data from subjects were analyzed and subjects were categorized into Low, Medium and High level groups according to stool Lactobacillus measurements. The primary endpoints were major adverse cardiac events (MACE). Univariate and multivariate Cox regression were used to analyze the relationship between Lactobacillus and prognosis. Kaplan-Meier survival curve was used to characterize the association between the risk of MACE and Lactobacillus levels. Spearman correlation analysis and trend test were used to assess the relationship between Lactobacillus and Clinical index. Results A total of 254 patients were included in the analysis. The age was 65.90±11.56 years old,and 152 (59.84%) were male. The follow-up time was 652 (548.25, 753) days. Multivariate Cox regression showed that patients with Lactobacillus &gt;7.1 copies/g presented lower risk of MACE (HR=0.179, 95% CI 0.076–0.422, P&lt;0.001), compared to patients with Lactobacillus ≤3.6 copies/g.This difference was statistically significant in STEMI (HR=0.210, 95% CI 0.082–0.542, P=0.001). Subgroup analysis indicated that Lactobacillus was a protective factor,whereas the value was more evident for male smokers over 60 years old and whose BNP over 1000 pg/mL.Spearman correlation analysis showed that Lactobacillus was negatively correlated with WBC, NEUT, hs-CRP, TNT, CK, CK-MB and BNP, while positively correlated with LVEF. With the increasing of Lactobacillus, WBC, NEUT, hs-CRP, TNT, CK, CK-MB and BNP showed a downward trend, while LVEF had an upward trend. Conclusion Lactobacillus can significantly reduce the risk of MACE in STEMI patients treated by PCI, especially for male smokers over 60 years old. The underlying mechanism may be related to the fact that Lactobacillus can reduce inflammatory reaction, lessen cardiac injury and improve cardiac function.

Primary percutaneous coronary intervention (PPCI) is recommended by the European Society of Cardiology (ESC) treatment guidelines as the preferred treatment for ST-elevation acute myocardial infarction (STEMI) whenever it is available within 90–120 minutes of the first medical contact. A survey conducted in 2008 in 51 ESC countries found that the annual incidence of hospital admissions for acute myocardial infarction is around 1,900 patients per million population, with an incidence of STEMI of about 800 per million. It showed that STEMI patients’ access to reperfusion therapy and the use of PPCI or thrombolysis (TL) vary considerably between countries. Northern, western and central Europe already have well-developed PPCI services, offering PPCI to 60–90 % of all STEMI patients. Southern Europe and the Balkans are still predominantly using TL. Where this is the case, a higher proportion of patients are left without any reperfusion treatment. The survey concluded that a nationwide PPCI strategy results in more patients being offered reperfusion therapy. To address the inequalities in STEMI patients’ access to life-saving PPCI, and to support the implementation of the ESC STEMI treatment guidelines in Europe, the Stent for Life (SFL) Initiative was launched jointly by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) and EuroPCR in 2008. National cardiac societies from Bulgaria, France, Greece, Serbia, Spain and Turkey signed the SFL Declaration at the ESC Congress in Barcelona in 2009. The aim of the SFL Initiative is to improve the delivery of, and STEMI patients’ access to, life-saving PPCI and thereby reduce mortality and morbidity. Currently, 10 national cardiac societies support the SFL Initiative in their respective countries. SFL national action programmes have been developed and are being implemented in several countries. The formation of regional PPCI networks involving emergency medical services, non-percutaneous coronary intervention hospitals and PPCI centres is considered to be a critical success factor in implementing PPCI services effectively. This article describes examples of how SFL countries are progressing in implementing their national programmes, thus increasing PPCI penetration in Europe.
