Fabry disease (FD) is an X-linked inherited lysosomal storage disorder caused by mutations in the GLA gene, encoding for the enzyme α-galactosidase A. Although hundreds of mutations in the GLA gene have been described, many of them are variants of unknown significance. Here we report a novel GLA mutation, p.Ile239Met, identified in a large Hungarian three-generation family with FD. A 69 year-old female index patient with a clinical history of renal failure, hypertrophic cardiomyopathy, and 2nd degree AV block was screened for mutation in the GLA gene...

A 59-year-old Japanese woman was admitted to a nearby hospital with dyspnea and general malaise. Transthoracic echocardiography revealed right ventricular (RV) dilatation with severely reduced systolic function and leftward shift of the intraventricular septum. She was initially diagnosed with acute right heart failure, and fell into cardiogenic shock requiring an intra-aortic balloon pump and inotropic agents. An endomyocardial biopsy (EMB) demonstrated extensive interstitial edema, infiltration of inflammatory cells including numerous eosinophils, and myocytolysis with eosinophil degranulation...

Many patients still have high blood pressure (BP) after treatment with angiotensin II type 1 (AT1) receptor blockers (ARBs). We compared the efficacy and safety of azilsartan to those of olmesartan in a prospective randomized clinical trial. Sixty-four hypertensive patients who were treated with ARBs other than azilsartan and olmesartan were enrolled in this study. We randomly assigned patients to changeover from their prior ARBs to either azilsartan or olmesartan, and followed the patients for 3 months. Systolic BP (SBP) in the azilsartan group was significantly decreased at 3 months, and diastolic BP (DBP) and pulse rate (PR) in the olmesartan group showed significant reductions after 3 months...

To investigate the postprocedural cardiovascular events and vascular outcomes, including hand ischemia and neurological compromise, after transulnar (TU) catheterization in ipsilateral radial artery occlusion.Previous randomized trials have shown that the transulnar (TU) approach for coronary angiogram and intervention has safety and outcomes similar to those of the transradial (TR) approach. However, the safety of the TU procedure when ipsilateral radial artery occlusion occurs is unknown.We retrospectively reviewed 87 TU cases with ipsilateral radial artery occlusion confirmed by a forearm angiogram...

Understanding the metabolic features of myocardial infarction (MI) is critical to its prevention and treatment. Here, we aimed to characterize the metabolic features of early MI using a tissue metabolomics method based on gas chromatography-mass spectrometry (GC-MS). Thirty-four pairs of infarcted myocardia and their matched non-infarcted myocardia were collected from 34 rats that underwent coronary artery ligation (CAL); their metabolic profiles were compared by GC-MS-based tissue metabolomics to characterize the metabolic features of MI...

We hypothesized that the effects of adaptive servo-ventilation (ASV) therapy were influenced by right-sided heart performance. This study aimed to clarify the interaction between the effects of ASV and right-sided heart performance in patients with stable heart failure (HF) with reduced ejection fraction (HFrEF).Twenty-six stable HF inpatients (left ventricular ejection fraction < 0.45, without moderate to severe mitral regurgitation (MR) were analyzed. Echocardiography was performed before and after 30 minutes of ASV...

Acute myocardial ischemia causes TQ depression and ST elevation. However, the effects of cardioprotective drugs such as β-blockers and Ca(++)-antagonists on the extent of TQ depression, ST elevation, and myocardial ischemic injury are not fully understood.We created a carotid-coronary shunt in 30 pigs, and extracellular K(+) ([K(+)]e), TQ, and ST segments were recorded simultaneously with K(+)-selective plunge electrodes placed in the left anterior descending artery (LAD) distribution during graded LAD flow reduction before and after administration of propranolol or verapamil...

With the increased use of intravascular catheters and devices, they have become the major non-malignant cause of superior vein cava (SVC) syndrome. We report a patient with liver cirrhosis who had received a peritoneovenous drainage catheter for refractory ascites, and then developed SVC syndrome because of concomitant occlusions of both the SVC and the drainage catheter. The patient regained patency of both the occluded vessel and the drainage catheter through percutaneous transluminal venoplasty, and there was dramatic improvement of clinical symptoms and good performance of the drainage catheter...

This study was conducted to assess whether any relationships exist between glucose fluctuations and electrocardiographic surrogate markers of reperfusion injury in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).We prospectively studied 63 consecutive patients with STEMI undergoing primary PCI. Patients had either diabetes (n = 30), impaired glucose tolerance (n = 26), impaired fasting glucose (n = 1), or normal glucose tolerance (n = 6). STsegment resolution (STR, %) was measured using electrocardiograms recorded 60 minutes after PCI...

We examined whether tolvaptan combined with an angiotensin II receptor blocker (ARB) or angiotensin converting enzyme inhibitor (ACE-I) is more effective than tolvaptan alone in the treatment of patients with heart failure (HF). Sixty-five hospitalized patients with acute decompensated HF were included in this study. They were divided into 2 groups; an ARB/ACE-I group (n = 44, who received ARB or ACE-I before the use of tolvaptan) and a non-ARB/ACE-I group (n = 21). There were no significant differences in patient characteristics including medications at baseline between the non-ARB/ACE-I and ARB/ACE-I groups with the exception of the percentages of hypertension and ischemic heart disease...

REVIEW
Hirofumi Tomiyama, Tomoko Saisu, Akira Yamashina
The FMDJ study, a multicenter prospective observational study conducted in Japan, demonstrated the acceptable reliability of measurement of flow-mediated vasodilatation (FMD) using a semi-automatic device in individual institutions. However, in about 10% of Japanese subjects, adequate scans to determine the brachial arterial diameter failed to be obtained. The prevalence of inadequate scans was higher in women than in men, while obesity had no influence on the inadequate scan rate. The FMDJ study also proposed that attending periodic refresher courses on the measurement of FMD is needed for maintaining competency...

Coronary spasm is abnormal contraction of an epicardial coronary artery resulting in myocardial ischemia. Coronary spasm induces not only depressed myocardial contractility, but also incomplete myocardial relaxation, which leads to elevated ventricular filling pressure. We herein report the case of a 55-year-old woman who had repeated acute heart failure caused by coronary spasm. Acetylcholine provocation test with simultaneous right heart catheterization was useful for the diagnosis of elevated ventricular filling pressure as well as coronary artery spasm...

Inflammation plays an important role in heart failure and diabetes mellitus. Traditional serum markers have limited predictive value in heart failure and diabetes. TNFR1 and TNFR2 (TNFR1/2) have been proven to be strongly associated with heart failure and diabetes complications. This study aimed to assess the association of sTNFR1 and sTNFR2 levels and incidental HF risk in diabetes patients.We detected the mRNA, protein, and serum expression of TNFR1/2, their downstream signaling pathway protein NF-kB, and JNK expression and some traditional serum inflammatory markers in a heart failure group without diabetes mellitus or abnormal glucose tolerance (n = 84), a diabetes mellitus group without heart failure (n = 86), and a heart failure with diabetes mellitus group (n = 86)...
