Background Transplantation of non-expanded peripheral blood mononuclear cells (PBMNCs) enhances neovessel formation in ischemic myocardium and limbs by releasing angiogenic factors. This study was designed to examine whether intracoronary transplantation of PBMNCs improves cardiac function after acute myocardial infarction (AMI). Methods and Results After successful percutaneous coronary intervention (PCI) for a ST-elevation AMI with occlusion of proximal left anterior descending coronary artery within 24 h, patients were assigned to either a control group or the PBMNC group that received intracoronary infusion of PBMNCs within 5 days after PCI. PBMNCs were obtained from patients by COBE spectra-apheresis and concentrated to 10 ml, 3.3 ml of which was infused via over-the-wire catheter. The primary endpoint was the global left ventricular ejection fraction (LVEF) change from baseline to 6 months' follow-up. The data showed that the absolute increase in LVEF was 7.4% in the control group and 13.4% (p=0.037 vs control) in the PBMNC group. Cell therapy resulted in a greater tendency of ΔRegional ejection fraction (EF) or significant improvement in the wall motion score index and Tc-99m-tetrofosmin perfusion defect score associated with the infarct area, compared with controls. Moreover, intracoronary administration of PBMNCs did not exacerbate either left ventricular (LV) end-diastolic and end-systolic volume expansion or high-risk arrhythmia, without any adverse clinical events. Conclusion Intracoronary infusion of non-expanded PBMNCs promotes improvement of LV systolic function. This less invasive and more feasible approach to collecting endothelial progenitor cells may provide a novel therapeutic option for improving cardiac function after AMI.

Background:The present study was performed to clarify whether the preoperative clinical symptoms for endovascular therapy (EVT) can predict post-EVT death and cardiovascular prognosis in Japanese patients with peripheral artery disease (PAD), including acute disease.Methods and Results:The TOkyo taMA peripheral vascular intervention research COmraDE (Toma-Code) Registry is a Japanese prospective cohort of 2,321 consecutive patients with PAD treated with EVT, in 34 hospitals in the Kanto and Kōshin’etsu regions, from August 2014 to August 2016. In total, 2,173 symptomatic patients were followed up for a median of 10.4 months, including 1,370 with claudication, 719 with critical limb ischemia (CLI), and 84 with acute limb ischemia (ALI) for EVT. The all-cause death rates per 100 person-years for claudication, CLI and ALI were 3.5, 26.2, and 24.5, respectively. Similarly, major adverse cardiac and cerebrovascular events (MACCE) rates per 100 person-years for claudication, CLI, ALI, and others were 5.2, 31.2, and 29.7, respectively. After adjusting for the predictors of all-cause death and MACCE, namely, age, body mass index <18, diabetes mellitus, dialysis, cerebrovascular disease, and low left ventricular ejection fraction, it was determined that the preoperative indication for EVT was strongly associated with all-cause death and MACCE.Conclusions:The preoperative clinical symptoms for EVT can predict the prognosis in patients with PAD undergoing EVT.

Objective The predictors of in-hospital outcomes after primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) complicated with heart failure or cardiogenic shock at presentation remain unclear. Methods Using the AMI-Kyoto Multi-Center Risk Study database, the clinical background characteristics, angiographic findings, primary PCI results, and in-hospital prognoses were retrospectively compared between primary PCI-treated AMI patients with a Killip class status of ≥2 (Killip 2-4 patients, n=390) and those with a Killip class 1 status (Killip 1 patients, n=1,057). Results The Killip 2-4 patients were more likely to have a higher age and proportion of women and exhibited a higher prevalence of previous myocardial infarction, diabetes mellitus and chronic kidney disease or anemia on admission, lower systolic blood pressure (SBP) values on admission, a higher rate of multivessels or left main trunk as the culprit artery, a larger number of diseased vessels, a lower Thrombolysis In Myocardial Infarction (TIMI) grade in the infarct-related artery (IRA) before/after primary PCI and a significantly higher in-hospital mortality rate than the Killip 1 patients. According to a multivariate analysis, age was found to be an independent positive predictor of in-hospital mortality, while admission SBP was an independent positive predictor of in-hospital survival in both groups. In contrast, anemia on admission was found to be an independent predictor of in-hospital death, while the TIMI 3 flow in the IRA after PCI was found to be an independent factor for survival in the Killip 2-4 patients, but not the Killip 1 patients. Conclusion Anemia on admission and the final TIMI 3 flow in the IRA are critical determinants of in-hospital death in AMI patients with a Killip class status of ≥2 undergoing primary PCI.
