    Abstract Background: Complete revascularization of the culprit and all significant nonculprit lesions in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and multivessel disease (MVD) reduces major adverse cardiac events, but optimal timing of revascularization remains unclear.
    Objectives: This study aims to compare immediate complete revascularization (ICR) and staged complete revascularization (SCR) in patients presenting with NSTE-ACS and MVD.
    Methods: This prespecified substudy of the BIOVASC (Percutaneous Complete Revascularization Strategies Using Sirolimus Eluting Biodegradable Polymer Coated Stents in Patients Presenting With Acute Coronary Syndrome and Multivessel Disease) trial included patients with NSTE-ACS and MVD. Risk differences of the primary composite outcome of all-cause mortality, myocardial infarction (MI), unplanned ischemia-driven revascularization (UIDR), or cerebrovascular events and its individual components were compared between ICR and SCR at 1 year.
    Results: The BIOVASC trial enrolled 1,525 patients; 917 patients presented with NSTE-ACS, of whom 459 were allocated to ICR and 458 to SCR. Incidences of the primary composite outcome were similar in the 2 groups (7.9% vs 10.1%; risk difference 2.2%; 95% CI: -1.5 to 6.0; P = 0.15). ICR was associated with a significant reduction of MIs (2.0% vs 5.3%; risk difference 3.3%; 95% CI: 0.9 to 5.7; P = 0.006), which was maintained after exclusion of procedure-related MIs occurring during the index or staged procedure (2.0% vs 4.4%; risk difference 2.4%; 95% CI: 0.1 to 4.7; P = 0.032). UIDRs were also reduced in the ICR group (4.2% vs 7.8%; risk difference 3.5%; 95% CI: 0.4 to 6.6; P = 0.018).
    Conclusions: ICR is safe in patients with NSTE-ACS and MVD and was associated with a reduction in MIs and UIDRs at 1 year.

    Abstract Background: In patients with acute coronary syndrome and multivessel coronary disease, complete revascularisation by percutaneous coronary intervention (PCI) is associated with improved clinical outcomes. We aimed to investigate whether PCI for non-culprit lesions should be attempted during the index procedure or staged.
    Methods: This prospective, open-label, non-inferiority, randomised trial was done at 29 hospitals across Belgium, Italy, the Netherlands, and Spain. We included patients aged 18-85 years presenting with ST-segment elevation myocardial infarction or non-ST-segment elevation acute coronary syndrome and multivessel (ie, two or more coronary arteries with a diameter of 2·5 mm or more and ≥70% stenosis based on visual estimation or positive coronary physiology testing) coronary artery disease with a clearly identifiable culprit lesion. A web-based randomisation module was used to randomly assign patients (1:1), with a random block size of four to eight, stratified by study centre, to undergo immediate complete revascularisation (PCI of the culprit lesion first, followed by other non-culprit lesions deemed to be clinically significant by the operator during the index procedure) or staged complete revascularisation (PCI of only the culprit lesion during the index procedure and PCI of all non-culprit lesions deemed to be clinically significant by the operator within 6 weeks after the index procedure). The primary outcome was the composite of all-cause mortality, myocardial infarction, any unplanned ischaemia-driven revascularisation, or cerebrovascular events at 1 year after the index procedure. Secondary outcomes included all-cause mortality, myocardial infarction, and unplanned ischaemia-driven revascularisation at 1 year after the index procedure. Primary and secondary outcomes were assessed in all randomly assigned patients by intention to treat. Non-inferiority of immediate to staged complete revascularisation was considered to be met if the upper boundary of the 95% CI of the hazard ratio (HR) for the primary outcome did not exceed 1·39. This trial is registered with ClinicalTrials.gov, NCT03621501.
    Findings: Between June 26, 2018, and Oct 21, 2021, 764 patients (median age 65·7 years [IQR 57·2-72·9] and 598 [78·3%] males) were randomly assigned to the immediate complete revascularisation group and 761 patients (median age 65·3 years [58·6-72·9] and 589 [77·4%] males) were randomly assigned to the staged complete revascularisation group, and were included in the intention-to-treat population. The primary outcome at 1 year occurred in 57 (7·6%) of 764 patients in the immediate complete revascularisation group and in 71 (9·4%) of 761 patients in the staged complete revascularisation group (HR 0·78, 95% CI 0·55-1·11, p
    Interpretation: In patients presenting with acute coronary syndrome and multivessel disease, immediate complete revascularisation was non-inferior to staged complete revascularisation for the primary composite outcome and was associated with a reduction in myocardial infarction and unplanned ischaemia-driven revascularisation.

    Abstract The long-term cardiac complications of radio(chemo)therapy for Hodgkin lymphoma include coronary artery disease, cardiac arrhythmias, valvular disease, pericardial disease, cardiomyopathy and heart failure. The extent of myocardial damage after radiotherapy is dependent on the dose, the volume and the technique of chest irradiation. Also, patient-specific factors, such as the age of the patient at the time of treatment and the presence of classical cardiac risk factors are supposed to be important. The relative risk of cardiovascular events is estimated to be 2 to 7 times higher than the general population. The patient's clinical picture can vary from asymptomatic to an acute presentation of end-stage coronary artery or valvular disease.

    Abstract Background. Circulating angiogenic cells (CAC) have been identified as important regulators of vascular biology. However, there is still considerable debate about the genotype and function of CAC. Methods and Results. Data from publicly available gene expression data sets were used to analyse the transcriptome of in vitro cultured CAC (CACiv). Genes and pathways of interest were further evaluated using qPCR comparing CACiv versus CD14+ monocytic cells. The CACiv transcriptome strongly related to tissue macrophages, and more specifically to regulatory M2c macrophages. The cytokine expression profile of CACiv was predominantly immune modulatory and resembled the cytokine expression of tumor-associated macrophages (TAM). Pathway analysis revealed previously unrecognized biological processes in CACiv, such as riboflavin metabolism and liver X receptor (LXR)/retinoid X receptor (RXR) and farnesoid X receptor (FXR)/retinoid X receptor (RXR) pathways. Analysis of endothelial-specific genes did not show evidence for endothelial transdifferentiation. Conclusions. CACiv are genotypically similar to regulatory M2c macrophages and lack signs of endothelial differentiation.

    Abstract Neuroglobin (NGB) is an oxygen-binding protein that is mainly expressed in nervous tissues where it is considered to be neuroprotective during ischemic brain injury. Interestingly, transgenic mice overexpressing NGB reveal cytoprotective effects on tissues lacking endogenous NGB, which might indicate a therapeutic role for NGB in a broad range of ischemic conditions. In the present study, we investigated the effect of NGB overexpression on survival as well as on the size and occurrence of myocardial infarctions (MI) in a mouse model of acute MI (AMI) and a model of advanced atherosclerosis (ApoE

    Abstract Background: Quantitative real-time PCR (qPCR) is a widely used technique for gene expression analysis. Its reliability is highly dependent upon selection of the appropriate reference genes for accurate gene expression normalization. In this study, we investigated the expression stability of 10 commonly used reference genes in a mouse myocardial infarction model.
    Methods & results: The expression stability of the 10 reference genes (Actb, B2m, Eef1a1, Gapdh, Hprt, Polr2a, Ppia, Rpl13a, Tbp, Tpt1) was analyzed using the geNorm software. Overall, the combination of Hprt, Rpl13a and Tpt1 was the most stable reference gene set in our experiments. Gapdh, Polr2a and Actb consistently showed the highest gene expression variability and the expression levels of Gapdh, Polr2a, Actb, B2m and Eef1a1 were found to be selectively up- or downregulated after myocardial infarction. We normalized the expression of Nppb and Vcam1, using different reference gene strategies and demonstrated that their induction after myocardial infarction was most clearly revealed with the optimal reference gene combination. However, the use of suboptimal reference gene combinations resulted in detrimental effects on gene expression levels and variability with a gradual loss of the expression differences and a significant reduction in statistical power.
    Conclusions: Hprt, Rpl13a and Tpt1 are a set of stably expressed reference genes for accurate gene expression normalization in myocardial infarction studies in mice. We found that Gapdh, Polr2a and Actb display high expression variability in mouse myocardial infarction tissues and that loss of statistical power and increase in sample size are the evident consequences of choosing suboptimal combinations of reference genes. We furthermore caution against the use of Gapdh, Polr2a, Actb, B2m and Eef1a1 for gene expression normalization in myocardial infarction studies because of selective up- or downregulation after myocardial infarction, which could potentially lead to biased study outcomes.
