Hyperuricemia is increasing in prevalence and this is paralleled by an increased incidence of acute gout. In addition, there is growing evidence of an association between high serum levels of uric acid (sUA) and cardiovascular disease (CVD). In this preliminary report, we present 12-16 week results from a multicenter, general practice study in which we evaluated the usefulness of febuxostat in a cohort of untreated patients with hyperuricemia with a high prevalence of CVD.

Methods: A total of 120 patients with dyslipidemia (46 men; mean age 66.5 years), who had not achieved the low density lipoprotein cholesterol (LDL-C) goal recommended by the Japan Atherosclerosis Society Guideline despite diet and exercise or any statin therapy, were enrolled and additionally treated with ezetimibe (10 mg/day) for 12 weeks.
A 45-year-old man developed fulminant myocarditis for which ventricular assist devices (intra-aortic balloon pumping and percutaneous cardiopulmonary support) were required for hemodynamic support. Echocardiography showed left ventricular akinesis and, since no improvement was noted on the following day, immunoglobulin (70 g/day for 2 days) was added to the therapy. The left ventricular ejection fraction increased to 25% and 40% at 12 and 36 h, respectively, representing a marked improvement in wall motion within a very short period.

The present study was undertaken to clarify the significance of transient LV wall thickening in patients with this disease. The subjects comprised 25 patients with acute lymphocytic myocarditis.

This study was undertaken in order to clarify the relationship between conduction disturbances and myocardial interstitial edema in AM. The subjects comprised 50 patients with acute lymphocytic myocarditis.

However, a 78-year-old man did not have symptoms and was hospitalized as a result of abnormalities observed on an incidentally obtained electrocardiogram (ECG). Several days later, he developed cardiogenic shock and fulminant myocarditis, which required percutaneous cardiopulmonary support; however, the cardiac failure persisted and he died approximately 4 months later.

One family member had experienced sudden death, and 2 others had died of heart failure, including 1 known to have had Fabry's disease. The patient was also diagnosed with Fabry's disease, based on reduced leukocyte alpha-galactosidase A activity, 2.

Aim: This investigation was undertaken to clarify the current status of steroid therapy for cardiac sarcoidosis in Japan.
Methods: A questionnaire survey was conducted throughout Japan concerning cases in which steroid therapy had been administered. Replies describing 52 cases (15 men, 37 women; mean age +/- SD, 59.
Background: Basal thinning of the interventricular septum (IVS) and atrioventricular block (AVB) are characteristic features of cardiac sarcoidosis. Since the conduction system passes along IVS, it has been considered that a close connection exists between basal thinning of IVS and AVB. However, neither the incidence of cases showing basal thinning of IVS nor the relation between it and AVB has been clarified.

A 30-year-old man with Brugada syndrome died suddenly. The heart weighed 380 g. The left ventricular wall showed mild thickening, and marked fatty tissue deposition was noted in the right ventricular outflow tract.

The expression of inducible nitric oxide synthase (iNOS) was earlier demonstrated in the ventricles of patients with dilated cardiomyopathy (DCM) although that of GCHI was not clarified. The present study was designed to determine the GCHI mRNA expression as well as to confirm iNOS mRNA expression in endomyocardial biopsy specimens from patients with DCM.
View Article and Find Full Text PDFTenascin-C (TN-C) is an extracellular matrix protein that is expressed transiently in close association with tissue remodelling in various body sites. In the heart, TN-C is only present during early stages of development, is not expressed in the normal adult, but reappears in pathological states. The purpose of this study was to analyse the expression of TN-C in myocardial tissue from myocarditis patients, and to evaluate the diagnostic value of immunostaining for TN-C in the assessment of inflammatory activity in biopsy specimens.

Methods And Results: Thirty-nine patients with acute lymphocytic myocarditis, excluding 8 who manifested shock at admission, were studied. The fulminant group was defined as 12 patients who developed shock after admission, requiring intraaortic balloon pumping or percutaneous cardiopulmonary support, and the non-fulminant group comprised the 27 patients without shock.
A variety of myocardial lesions have been demonstrated in atrial muscle in patients with sick sinus syndrome (SSS), but the right ventricular myocardium has not been studied in detail in a large series. Therefore, we performed right ventricular endomyocardial biopsies in 25 patients with SSS (SSS group), and the presence or absence of ventricular myocardial lesions was determined histologically. As a control, biopsies of corresponding sites in 12 normal autopsied hearts were obtained (N group).

However, no detailed studies have been performed on the sequential changes in the initial peripheral blood eosinophil count over the course of the disease. We measured the peripheral blood eosinophil count at the time of presentation in eight patients with eosinophilic myocarditis proven by endomyocardial biopsy and intermittently thereafter.
View Article and Find Full Text PDFApical hypertrophic cardiomyopathy has been divided into two entities: apical asymmetric septal hypertrophy (apical ASH) and apical symmetric hypertrophy (AH). The latter differs clinically from hypertrophic cardiomyopathy (HCM) with ASH, and it is unclear whether AH represents a distinct subtype of HCM. In the present study, the presence or absence and the extent of cardiac muscle cell disorganization, a histologic characteristic of HCM, were compared in patients with AH (n = 10) and ASH (n = 29) in whom cardiac biopsy specimens were obtained from the left ventricular apex and interventricular septum.

Background: The usefulness of corticosteroid therapy for cardiac sarcoidosis has not yet been fully clarified.
Methods: Of 40 patients diagnosed with cardiac sarcoidosis, twenty patients complicated by atrioventricular block but normal cardiac function (left ventricular ejection fraction > or = 50%) were divided retrospectively into one group (n = 7) receiving corticosteroids and another (n = 13) not receiving these agents. Over a mean observation period of 79.
It has been reported that some patients with acute myocarditis have transient ventricular thickening associated with narrowing of the left ventricular cavity caused by interstitial edema. The present study investigated this phenomenon in 20 patients with acute myocarditis. Based on the sum of the interventricular septal wall thickness and left ventricular posterior wall thickness (IVST + PWT), measured by M-mode echocardiography, patients were divided into group A (IVST + PWT >/=25 mm, n=12) and group B (IVST + PWT <25 mm, n=8).
View Article and Find Full Text PDFCardiac sarcoidosis induces heart failure death or sudden death in many cases and is thus often associated with a poor prognosis. In Japan 47-78% of sarcoidosis patients die of cardiac lesions. Early diagnosis is important in such cases, and a comprehensive judgment based on the endomyocardial biopsy, echocardiography and nuclear medicine examination findings should be made according to the 'Handbook of the Diagnosis of Cardiac Sarcoidosis'.
