Does colchicine decrease the rate of recurrence of acute idiopathic pericarditis treated with glucocorticoids?
The traditional treatment of acute pericarditis includes non-steroidal anti-inflammatory agents (NSAIDs) or glucocorticoids. The addition of colchicine has been found to reduce the rate of recurrences. Glucocorticoids, however, may attenuate this effect, although the available data are limited. We examined the impact of colchicine on the rate of recurrence of acute idiopathic pericarditis pretreated with prednisone. ⋯ The addition of colchicine to prednisone in patients admitted for acute idiopathic pericarditis does not reduce the risk of recurrence. This finding suggests that prednisone blunts the salutary effects of colchicine.

In-hospital mortality analysis of Japanese patients with acute coronary syndrome using the Tokyo CCU Network database: Applicability of the GRACE risk score.
The GRACE risk score was developed to predict in-hospital mortality for acute coronary syndrome (ACS) using multinational registries, but did not include Japanese data. Therefore, GRACE risk scores are not extensively used in Japan. The present study aimed to evaluate the relationship between the GRACE risk score and in-hospital mortality among Japanese patients with ACS using the Tokyo CCU (cardiovascular care unit) Network Database. ⋯ The GRACE risk score is a good predictor of in-hospital mortality for Japanese patients with STEMI or NSTEMI, and can help clinicians stratify patients by risk for optimal patient triage and early treatment management.

Cost effectiveness of transcatheter aortic valve implantation in patients with aortic stenosis in Japan.
Transcatheter aortic valve implantation (TAVI) is a less invasive treatment for elderly patients with aortic stenosis. However, the cost of TAVI is a major issue. This study analyzed the cost effectiveness of TAVI in Japan. ⋯ This study suggests that TAVI has good cost effectiveness for inoperable patients, but not for operable patients.

Conduction recovery and avoidance of permanent pacing after transcatheter aortic valve implantation.
Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with severe aortic stenosis and high surgical risk. Currently, various prosthesis types are available. Atrioventricular block (AVB) requiring pacemaker (PM) implantation is a typical complication after TAVI. This study investigated the recovery of AV node conduction and mid-term outcome of patients with or without PM implantation after TAVI according to prosthesis type. ⋯ Mid-term all-cause survival after TAVI seems to be independent of prosthesis type and PM implantation after TAVI. Intrinsic AV node conduction recovers in a significant proportion of patients. Therefore, regular PM interrogations including reprogramming are required to avoid unnecessary permanent right ventricular stimulation.

Clinical significance of the overshoot phenomena of respiratory gas indices during recovery from maximal exercise testing.
Overshoot phenomena of the gas exchange ratio (R:VCO2/VO2), ventilatory equivalent for O2 (VE/VO2), and end-tidal O2 pressure (PETO2) are commonly observed during recovery from maximal cardiopulmonary exercise testing (CPX). We investigated the clinical significance of the overshoots of these indices by comparing their magnitudes between healthy subjects and cardiac patients with left ventricular dysfunction. ⋯ We concluded that the overshoots of R, VE/VO2, and PETO2 during recovery from maximal exercise reflect the natural cardiopulmonary adaptation after exercise and are more prominent in subjects with better cardiopulmonary function.
