An autopsy case of tako-tsubo cardiomyopathy presenting ventricular tachycardia after pacemaker implantation.

We herein report a rare autopsy case of tako-tsubo cardiomyopathy (TTC) presenting ventricular tachycardia after pacemaker implantation. A 69-year-old male received a dual-chamber pacemaker implantation for complete atrioventricular block. He had no chest symptoms after the operation.

Iodine-123 metaiodobenzylguanidine imaging can predict future cardiac events in Japanese patients with Parkinson's disease.

Objectives: Iodine-123 metaiodobenzylguanidine (123I-MIBG) myocardial scintigraphy provides useful diagnostic information in differentiating Parkinson's disease (PD) from other neurological diseases. Moreover, a number of studies have reported that 123I-MIBG imaging provides powerful diagnostic and prognostic information in congestive heart failure (HF) patients. The aim of the present study was to investigate the cardiovascular predictive value of cardiac 123I-MIBG imaging in patients with PD.

Report from the Japanese registry of CPR for in-hospital cardiac arrest (J-RCPR).

Background: In-hospital cardiopulmonary arrest (CPA) is an important issue, but data in Japan are limited.

Methods And Results: To investigate in-hospital CPA, we conducted a prospective multicenter observational registry of in-hospital CPA and resuscitation in Japan (J-RCPR). During January 2008 to December 2009, patients were registered from 12 participating hospitals.
