Background: The treatment of LMCAD has shifted from coronary artery bypass grafting (CABG) to Percutaneous coronary intervention (PCI). However, data on long-term outcomes of PCI for LMCA disease, especially in patients with acute coronary syndrome (ACS) remains limited and conicting. This study aims to nd the association of the immediate and 4-year mortality in ACS patients with LMCA disease treated by PCI based on ejection fractions at admission. Methods: A retrospective analytical study was conducted. Patients were divided at admission into those with reduced left ventricular ejection fraction and those with preserved ejection fraction. Results: Forty (58.8%) of the patients presented with preserved EF. The mean age of the patients was 71.6±7.1 years. The mean LVEF of the preserved group was 61.6±4.3% and signicantly higher than that of the reduced group. Age and cardiovascular risk factor prole was similar between the two groups. Patients with reduced ejection fraction had signicantly higher levels of serum creatinine and signicantly lower levels of Hb and HDL. Mean hospital stay was signicantly longer for patients with preserved EF. In-hospital deaths were also similar between the two groups. The reduced EF group had a signicantly higher allcause mortality in the 4-year follow-up period. The mean years of follow-up for all participants was 4.2±1.3 years. Conclusion: It was seen that in patients presenting with ACS and undergoing PCI due to LMCAD, LVEF at admission, singly and in in multivariate regression is an important predictor of in hospital and 4-year mortality

Sirolimus Eluting Stent

Abstract Purpose:Ultra-thin strut polymer-free sirolimus eluting stent (UPF-SES) have two novel characteristics, ultra-thin strut and polymer-free coating, which have the potential to achieve early re-endotherialization. However, a little is known whether early vascular healing of UPF-SES can be achieved in patients with acute coronary syndrome (ACS).The aim of this study was to evaluate the vascular healing after an implantation of UPF-SES in patients with ACS using optical coherence tomography (OCT) at 3 months after the stent implantation. Methods:From September 2020 and January 2021, a total of 31 consecutive patients presenting with ACS who underwent OCT examinations at the initial percutaneous coronary intervention (PCI) and 3-month follow-up were enrolled in the USUI-ACS study. The endpoints of this study were neointimal strut coverage, malapposition, and mean neointimal hyperplasia (NIH) thickness at 3-month follow-up.Results:Over a mean follow-up of 91 days after the initial PCI, the follow-up OCT was examined. The median percentage of covered struts was 98.4% and malapposed struts 0%, and the mean NIH thickness was 60μm.Conclusions:UPF-SES exhibited an excellent early vascular healing at 3-months in patients with ACS.

AimsThere is a paucity of evidence supporting routine beta blocker (BB) use in patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). The aim of this study was to evaluate BB use post PCI and its association with mortality. Furthermore, the study aimed to evaluate the association between BB and mortality in the subgroups of patients with left ventricular ejection fraction (LVEF) <35%, LVEF 35%–50% and LVEF >50%.MethodsUsing a large PCI registry, data from patients with ACS between January 2005 and June 2017 who were alive at 30 days were analysed. Those patients taking BB at 30 days were compared with those who were not taking BB. The primary outcome was all-cause mortality. The mean follow-up was 5.3±3.5 years.ResultsOf the 17 562 patients, 83.3% were on BB. Mortality was lower in the BB group (13.1% vs 19.5%, p=0.0001). Multivariable Cox proportional hazards model showed that BB use was associated with lower overall mortality (adjusted HR 0.87, 95% CI 0.78 to 0.97, p=0.014). In the subgroup analysis, BB use was associated with reduced mortality in LVEF <35% (adjusted HR 0.63, 95% CI 0.44 to 0.91, p=0.013), LVEF 35%–50% (adjusted HR 0.80, 95% CI 0.68 to 0.95, p=0.01), but not LVEF >50% (adjusted HR 1.03, 95% CI 0.87 to 1.21, p=0.74).ConclusionBB use remains high and is associated with reduced mortality. This reduction in mortality is primarily seen in those with reduced ejection fraction, but not in those with preserved ejection fraction.

Abstract Background The aim of this study was to determine the difference in effects of beta-blockers on long-term clinical outcomes between ischemic heart disease (IHD) patients with mid-range ejection fraction (mrEF) and those with reduced ejection fraction (rEF). Methods Data were assessed of 3508 consecutive IHD patients who underwent percutaneous coronary intervention (PCI) between 1997 and 2011. Among them, 316 patients with mrEF (EF = 40–49%) and 201 patients with rEF (EF < 40%) were identified. They were assigned to groups according to users and non-users of beta-blockers and effects of beta-blockers were assessed between mrEF and rEF patients, separately. The primary outcome was a composite of all-cause death and non-fatal acute coronary syndrome. Results The median follow-up period was 5.5 years in mrEF patients and 4.3 years in rEF patients. Cumulative event-free survival was significantly lower in the group with beta-blockers than in the group without beta-blockers in rEF (p = 0.003), whereas no difference was observed in mrEF (p = 0.137) between those with and without beta-blockers. In the multivariate analysis, use of beta-blockers was associated with reduction in clinical outcomes in patients with rEF (hazard ratio (HR), 0.59; 95% confidence interval (CI), 0.36–0.97; p = 0.036), whereas no association was observed among those with mrEF (HR 0.74; 95% CI 0.49–1.10; p = 0.137). Conclusions Our observational study showed that use of beta-blockers was not associated with long-term clinical outcomes in IHD patients with mrEF, whereas a significant association was observed in those with rEF.

Background: Very little data exists regarding percutaneous coronary intervention (PCI) as an alternative to coronary artery bypass graft (CABG) for the treatment of unprotected left main disease (LMD) in octogenarians, and no studies to date have compared CABG and PCI for the treatment of LMD in this population. The objectives of our study were to compare the acute and midterm follow-up results of PCI and CABG for the treatment of significant LMD in octogenarians. Methods: A total of 163 consecutive patients ≥80 years old diagnosed with LMD have undergone coronary revascularization in our center between 2002 and 2006. One hundred and one patients underwent CABG and 62 patients had PCI (non-surgical candidates: 30%, very high surgical risk patients: 61%, patient refusal of CABG: 9%). All complications occurring within the first 30 days following the procedure were recorded, and major adverse cardiovascular events -MACCE- (cardiac death, myocardial infarction, cerebrovascular event, revascularization) were evaluated at follow-up. Results: Patients who underwent PCI were older (85 ± 3 yrs vs. 82 ± 2 yrs, p<0.0001), presented more frequently with an acute coronary syndrome (92% vs. 50%, p<0.0001), and had a higher EuroSCORE (9.5 ± 2.7 vs. 8.5 ± 2.5, p=0.01). Drug-eluting stents were used in 48% of PCI patients. There were no significant differences in the incidence of MACCE at 30 days between groups (CABG: 28%, PCI: 19%, p=0.22), but the CABG group was associated with a higher rate of atrial fibrillation (48% vs. 14%, p<0.0001) and acute renal failure (17% vs. 6%, p=0.05). The incidence of MACCE occurring between 30 days and 24 ± 17 months follow-up was higher in the PCI group (32% vs. 13%, p=0.005), but the cumulative incidence of MACCE was similar in both groups (CABG 39% vs. PCI 44%, p=0.53). Conclusions: PCI was associated with a 30-day cardiac event rate similar to that of CABG for the treatment of unprotected LMD in octogenarians. Surgical patients experienced fewer cardiac events during the follow-up period, but the cardiovascular event-free survival rate was similar between groups at 2-year follow-up. Further randomized studies with longer-term follow-up comparing both revascularization strategies in this high risk coronary population are warranted.

Echocardiographic Parameters

Different ways have been used to stratify risk in acute coronary syndrome (ACS) patients. The aim of the study was to examine the usefulness of echocardiographic parameters as predictors of in-hospital outcome in patients with ACS after percutaneous coronary intervention (PCI). A data of 2030 patients with diagnosis of ACS hospitalized from December 2008 to December 2011 was used to develop a risk model based on echocardiographic parameters using the binary logistic regression. This model was independently evaluated in validation cohort prospectively (954 patients admitted during 2012). In-hospital mortality in derivation cohort was 7.73%, and 6.28% in validation cohort. Developed model has been designed with 4 independent echocardiographic predictors of in-hospital mortality: left ventricular ejection fraction (LVEF RR=0.892; 95%CI=0.854–0.932,P<0.0005), aortic leaflet separation diameter (AOvs RR=0.131; 95%CI=0.027–0.627,P=0.011), right ventricle diameter (RV RR=2.675; 95%CI=1.109–6.448,P=0.028) and right ventricle systolic pressure (RVSP RR=1.036; 95%CI=1.000–1.074,P=0.048). Model has good prognostic accuracy (AUROC=0.84) and it retains good (AUROC=0.78) when testing on the validation cohort. Risks for in-hospital mortality after PCI in ACS patients using echocardiographic measurements could be accurately predicted in contemporary practice. Incorporation of such developed model should facilitate research, clinical decisions, and optimizing treatment strategy in selected high risk ACS patients.
