Comparative StudyComparison of clinical outcomes between octogenarians and non-octogenarians with acute myocardial infarction in the drug-eluting stent era: analysis of the Korean Acute Myocardial Infarction Registry.
Octogenarians (age ≥ 80 years) with coronary artery disease constitute a high-risk group. However, octogenarian patients with acute myocardial infarction (AMI) in the drug-eluting stents (DES) era have not been widely reported. We aimed to identify clinical outcomes in octogenarian compared with non-octogenarian AMI patients. ⋯ Octogenarian AMI patients have higher rates of mortality and MACE even in the DES era. According to KAMIR subgroup analysis, the TLR/TVR rates in octogenarians were comparable to those in non-octogenarian AMI patients.

Initial experience using Excimer laser for the extraction of chronically implanted pacemaker and implantable cardioverter defibrillator leads in Japanese patients.
Given the exponential growth in cardiac device implantations, the need for less invasive lead extraction is increasing. The Excimer laser was approved for lead removal in Japan in 2010. The present study reports the initial experience using this novel technique to extract chronically implanted pacemaker and implantable cardioverter defibrillator (ICD) leads from Japanese patients. ⋯ Laser sheaths appear to provide a feasible and effective means of extracting chronically implanted pacemaker and ICD leads in Japanese patients.

Randomized Controlled TrialEffect on periprocedural myocardial infarction of intra-coronary nicorandil prior to percutaneous coronary intervention in stable and unstable angina.
Intravenous nicorandil infusion dilates the coronary artery and reduces inflammation, coronary spasm, and arrhythmia. Periprocedural myocardial infarction (PMI) is a frequent and prognostically important complication of percutaneous coronary intervention (PCI). This prospective randomized study was designed to evaluate the efficacy of intracoronary nicorandil on PMI after elective PCI. ⋯ Intra-coronary nicorandil infusion had no significant effect on PMI and cardiac enzymes after PCI in patients with stable or unstable angina.

Correlation between inflammation state and successful medical cardioversion using bepridil for refractory atrial fibrillation.
It has been reported that inflammation is associated with long-term maintenance of sinus rhythm after electrical cardioversion for non-valvular atrial fibrillation (AF). However, the relation between high-sensitive C-reactive protein (hs-CRP) and the recurrence of AF after medical cardioversion is unknown. On the other hand, bepridil is very effective in restoring sinus rhythm for patients with refractory AF. ⋯ Bepridil is effective in restoring sinus rhythm for refractory AF patients. Inflammation, in addition to left atrial dimension, may be associated with successful cardioversion using bepridil.

Clinical characteristics and long-term clinical outcomes of Japanese heart failure patients with preserved versus reduced left ventricular ejection fraction: a prospective cohort of Shinken Database 2004-2011.
Clinical data on the mortality and morbidity of unselected Japanese patients with heart failure (HF) are limited. In this study, we aimed to determine the clinical characteristics, long-term outcomes, and prognostic factors of Japanese HF patients with preserved or reduced left ventricular ejection fraction (LVEF). ⋯ This prospective cohort study identified the clinical characteristics, long-term outcomes, and prognostic factors of Japanese HF patients with reduced and preserved ejection fractions in a real-world clinical setting.
