The association of serum adiponectin level with activities of daily living in hospitalized elderly patients with heart failure.

Background: Several studies have reported a relationship between elevated serum adiponectin levels and poor outcomes in patients with heart failure (HF). However, data on the activities of daily living (ADL) in elderly patients with HF are limited.

Methods: We evaluated 218 hospitalized elderly (≥65 years) patients with HF who underwent a comprehensive cardiac rehabilitation (CR) program during hospitalization.

Beating pulmonary vein sign during catheter ablation.

The beating of a pulmonary vein during cardiac catheterization is a rare phenomenon caused by the heart beating through the pericardial effusion when a cardiac tamponade occurs. This "beating pulmonary vein" sign is useful for early detection of a tamponade before circulatory collapse occurs.

Predictive value of abdominal aortic calcification index for mid-term cardiovascular events in patients with acute coronary syndrome.

The utility of abdominal aortic calcification (AAC) for prediction of cardiovascular events (CVEs) in patients with acute coronary syndrome (ACS) remains to be determined. The aim of this prospective study was to determine the predictive value of the abdominal aortic calcification index (ACI), a semi-quantitative measure of AAC, for CVEs in patients with ACS. We evaluated 314 patients with ACS.

Association of smoking with prevalence of common diseases and metabolic abnormalities in community-dwelling Japanese individuals.

Smoking is a significant risk factor for cardiovascular diseases (CVDs). Given that certain common pathologies, including hypertension, dyslipidemia and type 2 diabetes mellitus, are major risk factors for CVDs, the association of smoking with CVDs may be attributable, at least in part, to its effects on common diseases. The aim of the present study was to determine the association of smoking with the prevalence of common diseases and metabolic abnormalities in community-dwelling Japanese individuals.

Coronary Artery Spasm during Cryoballoon Ablation in a Patient with Atrial Fibrillation.

The patient was a 63-year-old man with drug-resistant atrial fibrillation who developed coronary spasm during cryoballoon ablation (CBA). CBA was started from the left inferior pulmonary vein. ST elevations in II, III, and aVf, with reciprocal ST depressions in V2-5, occurred in association with chest pain just after balloon rewarming and deflation, and the patient's blood pressure fell to 50 mmHg.

Association of genetic variants with atrial fibrillation.

Recent genome-wide association studies (GWASs) identified various genes and loci that confer susceptibility to coronary artery disease or myocardial infarction among Caucasian populations. As myocardial ischemia is an important risk factor for atrial fibrillation, we hypothesized that certain polymorphisms may contribute to the genetic susceptibility to atrial fibrillation through affecting the susceptibility to coronary artery disease. The aim of the present study was to examine the possible association of atrial fibrillation in Japanese individuals with 29 polymorphisms identified as susceptibility loci for coronary artery disease or myocardial infarction in the meta-analyses of GWASs in Caucasian populations.

Association of and polymorphisms with metabolic syndrome.

Although genome-wide association studies (GWASs) have identified various genes and loci in predisposition to metabolic syndrome (MetS) or each component of this condition, the genetic basis of MetS in individuals remains to be identified definitively. The aim of the present study was to examine the possible association of MetS in individuals with 29 polymorphisms that were previously identified as susceptibility loci for coronary artery disease or myocardial infarction by meta-analyses of GWASs. The study population comprised 1,822 subjects with MetS and 1,096 controls.

Association of and polymorphisms with ischemic stroke.

Recent genome-wide association studies (GWASs) and their meta-analyses have identified various genes and loci underlying the predisposition to ischemic stroke or coronary artery disease in Caucasian populations. Given that ischemic stroke and coronary artery disease may have a shared genetic architecture, certain polymorphisms may confer genetic susceptibility to these two diseases. The aim of the present study was to examine the possible association of ischemic stroke with 29 single-nucleotide polymorphisms (SNPs) previously identified by the meta-analyses of GWASs as susceptibility loci for coronary artery disease.

A case of floating thrombus in the ascending aorta that caused recurrent peripheral arterial embolic events.

We report the case of a 62-year-old man with recurrent arterial embolisms to his arms caused by a thrombosis of the ascending aorta. He had developed a left brachial artery embolism 8 years previously, but presented with a right brachial artery embolus on this occasion. A clot-like mass was seen in the ascending aorta on computed tomography without significant atherosclerosis.
