The effects of prehospital epinephrine administration on post-arrest neurological outcome in out-of-hospital cardiac arrest (OHCA) patients with non-shockable rhythm remain unclear. To examine the time-dependent effectiveness of prehospital epinephrine administration, we analyzed 118,396 bystander-witnessed OHCA patients with non-shockable rhythm from the prospectively recorded all-Japan OHCA registry between 2011 and 2014. Patients who achieved prehospital return of spontaneous circulation without prehospital epinephrine administration were excluded. ⋯ Multivariate logistic regression analysis demonstrated that there was no significant difference in the chance of 1-month CPC 1-2 between patients who arrived at hospital in ≤ 10 min without prehospital epinephrine administration and patients with time to epinephrine administration ≤ 19 min. However, compared to patients who arrived at hospital in ≤ 10 min without prehospital epinephrine administration, patients with time to epinephrine administration ≥ 20 min and patients who arrived at hospital in 11-19, and ≥ 20 min without prehospital epinephrine administration were significantly associated with decreased chance of 1-month CPC 1-2 (p < 0.05, < 0.05, and < 0.001, respectively). In conclusion, when prehospital CPR duration from CPR initiation by EMS providers to hospital arrival estimated to be ≥ 11 min, prehospital epinephrine administered ≤ 19 min from CPR initiation by EMS providers could improve neurologically intact survival in bystander-witnessed OHCA patients with non-shockable rhythm.

Observational Study
Combined effect of nutritional status on long-term outcomes in patients with coronary artery disease undergoing percutaneous coronary intervention.
Previous studies have reported the prognostic value of objective nutritional indices such as the Controlling Nutritional Status (CONUT) score, Geriatric Nutritional Risk Index (GNRI) and Prognostic Nutritional Index (PNI). However, the effects of these indices in patients with coronary artery disease (CAD) who have undergone percutaneous coronary intervention (PCI) remain unclear. Furthermore, there are insufficient data to combine these indices. ⋯ Kaplan-Meier curves showed ongoing divergence in rates of death among nutritional statuses determined by the novel score (log rank test, p < 0.0001). Multivariate Cox hazard analysis showed that patients with a Combined Objective Nutritional Score of 3 showed 2.91-fold (95% confidence interval (CI) 2.10-4.00; p < 0.0001) and 2.16-fold (95% CI 1.15-3.92; p = 0.02) increases in risk of mortality and cardiac mortality compared with patients with a Combined Objective Nutritional Score of 0. In conclusion, malnutrition as evaluated by the Combined Objective Nutritional Score was significantly associated with worse long-term cardiovascular outcomes among CAD patients who underwent PCI.

Genetic variations of genes encoding the endothelial nitric oxide synthase (eNOS) and the NADH/NADPH oxidase system are related with atherosclerosis in the general population, but their significance in women is not sufficiently assessed. We investigated the potential association between the G894T polymorphism of the NOS3 gene and the C242T polymorphism of the CYBA gene with subclinical vascular disease. Seventy (70) healthy, normally ovulating, premenopausal women were recruited for this study. ⋯ In healthy premenopausal women, the CYBA C242T polymorphism is an independent determinant of endothelial function and subclinical atherosclerosis of the carotid arteries. The NOS3 G894T polymorphic variant also correlated with atherosclerosis, an association probably mediated by the traditional risk factors for CVD. The relevance of these findings in the clinical setting remains to be elucidated.

Transcatheter aortic valve implantation (TAVI) has been established as a low-invasive therapy for aortic stenosis, but circulatory collapse necessitating mechanical circulatory support could occur during TAVI due to procedure itself or procedural complications. The purpose of this study is to describe the outcomes of patients requiring extracorporeal membrane oxygenation (ECMO) in TAVI. Among 384 consecutive patients undergoing TAVI from April 2010 to July 2017 in Sakakibara Heart Institute, we evaluated seven patients (1.8%) who required ECMO during procedure. ⋯ ECMO is effective and a safe mechanical support device during TAVI. The mid-term outcomes of patients who needed ECMO were unfavorable. Further evolution of transcatheter heart valve is essential, and prophylactic ECMO may contribute to better prognosis in selected patients.

Door to balloon (D2B) time was reported an important factor of the clinical outcome of patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). D2B time is influenced by various factors; however, modifiable factors have not been adequately evaluated. The purpose of this study was to identify modifiable factors associated with prolonged D2B time. ⋯ The median D2B time for the entire cohort was 69 min (interquartile range 54-89) and 24% had a D2B time of > 90 min. Modifiable factors associated with prolonged treatment time (D2B time > 90 min) were electrocardiogram (ECG) to puncture time > 50 min [odds ratios (OR) 96.0, 95% confidence intervals (95% CI) 25.1-652.5, P < 0.0001), door to ECG time > 10 min (OR 49.8, 95% CI 11.8-357.5, P < 0.0001), and puncture to balloon time > 30 min (OR 48.5, 95% CI 12.0-333.8, P < 0.0001). ECG to puncture time > 50 min was the most important modifiable factor associated with prolonged D2B time in STEMI patients.
