Impact of preoperative dual antiplatelet therapy on bleeding complications in patients with acute coronary syndromes who undergo urgent coronary artery bypass grafting.
A 5- to 7-day washout period before coronary artery bypass grafting (CABG) is recommended for patients who have recently received a thienopyridine derivative; however, data supporting this guideline recommendation are lacking in Japanese patients. ⋯ Preoperative DAPT increases the risk of CABG-related major bleeding in Japanese patients with ACS undergoing urgent CABG.

Observational StudyClinical outcome of 2nd generation cryoballoon pulmonary vein isolation in patients over 75 years of age.
Pulmonary vein isolation is an established therapy for symptomatic atrial fibrillation. Despite the fact that incidence and prevalence of atrial fibrillation increases with age, patients over 75 years of age have been excluded in all major atrial fibrillation ablation trials. Pulmonary vein isolation with the cryoballoon has been shown to be equally effective compared to irrigated radiofrequency catheter ablation, but patients over 75 years have also been excluded. The 2nd generation cryoballoon has shown superior efficacy compared to the 1st generation cryoballoon. The aim of the study was to assess the efficacy of pulmonary vein isolation with the 2nd generation cryoballoon for symptomatic atrial fibrillation in elderly patients over 75 years. ⋯ Pulmonary vein isolation with the 2nd generation cryoballoon appears to be an effective treatment for symptomatic atrial fibrillation also in patients over 75 years of age.

The prognostic impact of uric acid in patients with severely decompensated acute heart failure.
The serum level of uric acid (UA) is a well-known prognostic factor for heart failure (HF) patients. However, the prognostic impact of hyperuricemia and the factors that induce hyperuricemia in acute HF (AHF) patients are not well understood. ⋯ The serum UA level was an independent predictor in patients who were hospitalized during an emergent situation for AHF. An elevated serum UA level on admission was associated with the presence of CKD and the use of loop diuretics. These factors were also associated with adverse outcomes in hyperuricemic patients with AHF.

Prognostic effect of estimated glomerular filtration rate in patients with cardiogenic shock or cardiac arrest undergoing percutaneous veno-arterial extracorporeal membrane oxygenation.
Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) can improve survival in patients with cardiogenic shock or cardiac arrest. We investigated the association between initial renal function and clinical outcome in patients undergoing VA-ECMO for cardiogenic shock and cardiac arrest. ⋯ An initial low eGFR may predict worse clinical outcome in patients undergoing VA-ECMO for cardiogenic shock and cardiac arrest.

Comparative StudyComparison of modern risk scores in predicting operative mortality for patients undergoing aortic valve replacement for aortic stenosis.
The aim of our study was to examine and compare the predictive value of operative mortality of the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, the Society of Thoracic surgeons (STS) score, the Ambler score, and the Japan score in patients undergoing aortic valve replacement (AVR) for aortic stenosis (AS). ⋯ The EuroSCORE II and the Japan score showed superior ability of calibration, but the STS score and the Ambler score overestimated the risk. However, the discrimination power was similar among the four risk scores. In the last quartile of risk, the EuroSCORE II gave an excellent predictive performance.
