Background: It has been reported that patients with acute myocardial infarction (AMI) transferred to low-volume primary percutaneous coronary intervention (PCI) hospitals (<115/year) in low population density areas experience higher in-hospital mortality rates. This study compared in-hospital outcomes of patients admitted to high-volume primary PCI hospitals (≥115/year) with those for other regional general hospitals.Methods and Results: Retrospective analysis was conducted on data obtained from 2,453 patients with AMI admitted to hospitals in Iwate Prefecture (2014–2018). Multivariate analysis revealed that the in-hospital mortality rate of AMI among patients in regional general hospitals was significantly higher than among patients in high-volume hospitals. However, no significant difference in mortality rate was observed among patients with ST-elevation myocardial infarction (STEMI) undergoing primary PCI. Although no significant difference was found in the in-hospital mortality rate of patients with Killip class I STEMI, significantly lower in-hospital mortality rates were observed in patients admitted in high-volume hospitals for Killip classes II, III, and IV.Conclusions: Although in-hospital outcomes for patients with STEMI undergoing primary PCI were similar, patients with heart failure or cardiogenic shock exhibited better in-hospital outcomes in high-volume primary PCI hospitals than those in regional general hospitals.

Background:Nutritional status has been reported to be a predictor of the outcomes of critical limb ischemia. However, there have been no reports of the association between nutritional status and the prognosis of patients with intermittent claudication (IC). The aim of this study was to examine whether or not the geriatric nutritional risk index (GNRI) is independently associated with the long-term outcomes of elderly patients following open bypass for IC.Methods and Results:The preoperative nutritional status of patients aged ≥65 years undergoing infrainguinal bypass for IC between 1991 and 2017 was retrospectively evaluated using the GNRI. Patients were divided into 3 groups based on the GNRI: Group I (normal nutritional risk), GNRI >98; Group II (low nutritional risk), GNRI 92 to ≤98; Group III (moderate to high nutritional risk), GNRI <92. The amputation-free survival (AFS), overall survival, and freedom from cardiovascular death up to 5 years were calculated by Kaplan-Meier method and a multivariate analysis was performed to detect independent predictors of each outcome. Group I showed superior outcomes to Group III for each of the 3 outcomes and the multivariate analysis showed that GNRI was an independent predictor of AFS.Conclusions:The GNRI was independently associated with the AFS of elderly patients who underwent open bypass for IC.
