Corneal dystrophy typically refers to a group of rare hereditary disorders with heterogeneous genetic background. A comprehensive molecular analysis was performed characterize the spectrum corneal dystrophies in Korean patients. Patients various underwent thorough ophthalmic examination, histopathologic and Sanger sequencing. total 120 probands were included, mean age 50 years (SD = 18 years) 70% female. 26 mutations five genes (14 clearly pathogenic 12 likely pathogenic) identified 49...

Osteoprotegerin (OPG) is a kind of tumor necrosis factor, which related to bone metabolism and vascular calcification. The increase concentration in serum cardiovascular diseases humans. purpose this study was figure out the relevance between osteoprotegerin carotid Serum OPG concentrations were compared 145 patients who underwent sonography (average age: 68 ± 9 years old, male: female = 81:64). A calcified plaque (CP) (37 people [27%]), noncalcified (NCP) (54 [37%]), nonplaque (NP) [37%])...

The importance of the right ventricle (RV) has been increasingly recognized, and accurate RV measurement become necessary. However, assessment with two-dimensional (2D) echocardiography several limitations. As development novel methods for continues, we can expect more accordant values related to geometry.Fifty-eight subjects who were examined by transthoracic (TTE) immediately before after hemodialysis (HD) enrolled. Real-time, full-volume, three-dimensional (3D) echocardiographic images...

Abstract Background The aim of this study was to examine left ventricular (LV) function in untreated, newly diagnosed hypertensive patients with morning blood pressure surge (MBPS) status using three-dimensional (3D) speckle tracking echocardiography (STE). Methods In study, 163 were included, and all underwent 24-h ambulatory monitoring (ABPM). According ABPM, participants divided into a MBPS group non-MBPS group. entire population examined by complete two-dimensional (2D) transthoracic...

The differential diagnosis of hypercalcaemia in patients with end-stage renal disease undergoing dialysis should be considered for causes related or unrelated to failure itself therapies failure. In particular, peritoneal may hinder awareness a clinical problem due its own peculiarities and effects on homeostasis the body, thus creating misconceptions interpreting laboratory data diagnosing disease.

It has been shown that triple antiplatelet therapy with cilostazol results in better clinical outcomes than dual patients treated a first-generation drug-eluting stent (DES); however, it is unclear whether similar efficacy after the implantation of second-generation DES. In COACT (Cath Olic medical center percutAneous Coronary Tervention) registry, 1248 study subjects who underwent percutaneous coronary intervention an everolimus- or zotarolimus-eluting (Endeavor, Xience V, Promus) were...

High coronary calcium score (CCS) and post-procedural cardiac enzyme may be related with poor outcomes in patients stent implantation.A total of 1,072 (63.2% male, mean age: 61.7±10.3 years) who underwent multi-detect computed tomography at index procedure follow-up angiography (CAG) after drug-eluting (DES) were divided into two groups: those without target lesion revascularization (TLR; >50% reduction luminal diameter or angina symptoms on CAG). The CCSs for predicting elucidated.There no...

Central aortic systolic blood pressure (CBP) measured by carotid-femoral pulse wave analysis (cfPWA) is a gold standard method to estimate true arterial pressure. However, the impact of CBP level radial PWA on cardiovascular (CV) risk assessment unclear.
