Cardiac fibrosis triggered by pressure overload represents one of the major challenges in the treatment of cardiovascular diseases. MicroRNA (miRNA/miR)‑155, a member of the small RNA family, has previously been demonstrated to be associated with cardiac inflammation. However, the effect of miR‑155 on cardiac fibrosis induced by angiotensin II (Ang II), particularly in cardiac fibroblasts, requires further investigation. The present study aimed to investigate the effect of miR‑155 in Ang II‑induced cardiac fibrosis using animal models and cardiac fibroblasts...

microRNA 21 (miRNA‑21) promotes the development of cardiac fibrosis, hypertrophy and heart failure. However, whether it can be used as a biomarker for the diagnosis and prognosis of heart failure remains unclear. The current study assessed circulating miRNA‑21 as a viable indicator for diagnosis and prognosis of heart failure. The levels of miRNA‑21 and brain natriuretic peptide were measured in serum obtained from the peripheral vein (miRNA‑21‑PV) and coronary sinus (miRNA‑21‑CS) of 80 patients with heart failure and 40 control individuals via reverse transcription‑quantitative polymerase chain reaction and ELISA, respectively...

Background In older adults with stroke, there is an increased risk of cardiovascular events in the intermediate period, up to one year after stroke. The risk of cardiovascular events in this period in young adults after stroke has not been studied. We hypothesized that in the intermediate risk period, young adults with ischemic stroke have an increased risk of recurrent stroke and a smaller increase of cardiac events. Methods Using the National Readmissions Database during the year 2013, we identified ischemic stroke admissions among those aged 18-45 years using International Classification of Disease, Ninth Revision, Clinical Modification codes to identify index vascular events and risk factors...

Alternatives to adrenaline with lignocaine local anesthesia, such as clonidine, have been trialed in various randomized, controlled trials. Therefore, the aim of the present systematic review was to compile the available evidence on using clonidine with lignocaine for dental anesthesia. Electronic databases were searched for eligible studies. A data-extraction form was created, extracted data were analyzed using non-Cochrane mode in RevMan 5.3 software. Heterogeneity between the studies were assessed using the forest plot, I(2) statistics (where >50% was considered to have moderate-to-severe heterogeneity), and χ(2) -test...

Cardiotoxicity is a well-known side effect of doxorubicin (DOX), but the mechanisms leading to this phenomenon are still not completely clear. Prediction of drug-induced dysfunction onset is difficult and is still largely based on detection of cardiac troponin (cTn), a circulating marker of heart damage. In the last years, several investigations focused on the possible involvement of microRNAs (miRNAs) in DOX-induced toxicity in vitro, with contrasting results. Recently, several groups employed animal models to mimic patient's condition, investigate the biological pathways perturbed by DOX, and identify diagnostic markers of cardiotoxicity...

The scanning-beam digital x-ray (SBDX) system is an inverse geometry x-ray fluoroscopy technology that performs real-time tomosynthesis at planes perpendicular to the source-detector axis. The live display is a composite image which portrays sharp features (e.g. coronary arteries) extracted from a 16 cm thick reconstruction volume. We present a method for automatically determining the position of the cardiac volume prior to acquisition of a coronary angiogram. In the algorithm, a single non-contrast frame is reconstructed over a 44 cm thickness using shift-and-add digital tomosynthesis...

BACKGROUND: Fabry Disease is a X-linked lysosomal storage disorder caused by the deficient activity of α-galactosidase A due to mutations in the GLA gene, which may be associated with increased left ventricular wall thickness, and mimic the morphologic features of hypertrophic cardiomyopathy. Management strategies for these two diseases diverge, with Fabry disease-specific treatment utilizing recombinant α-galactosidase A enzyme replacement therapy. METHODS: We studied a prospectively assembled consecutive cohort of 585 patients (71% male) from two hypertrophic cardiomyopathy tertiary referral centers by screening for low α-galactosidase A activity in dried blood spots...

The medial preoptic area (mPOA) participates in the temperature and cardiovascular control. The mPOA receives inputs from limbic structures and sends projections to hypothalamus and brainstem. Moreover, stress elicits pronounced neuronal activation in mPOA, suggesting its involvement in central neural pathway mediating stress responses. In the present study, we report the effect of acute mPOA neurotransmission inhibition using cobalt chloride (CoCl2-nonselective synapse blocker) on the mean arterial pressure (MAP), heart rate (HR), body and tail temperature (Tbody and Ttail, respectively), as well as on the HR component of baroreflex...

INTRODUCTION: The interval from J-point to T-wave peak (JTp) in ECG is a new biomarker able to identify drugs that prolong the QT interval but have different ion channel effects. If JTp is not prolonged, the prolonged QT may be associated with multi ion channel block that may have low torsade de pointes risk. From the automatic ECG measurement perspective, accurate and repeatable measurement of JTp involves different challenges than QT. We evaluated algorithm performance and JTp challenges using the Philips DXL diagnostic 12/16/18-lead algorithm...

Cardiovascular disease is the leading cause of death in patients with end-stage renal disease (ESRD) and often goes undetected. Abnormal coronary flow reserve (CFR), which predicts increased risk of cardiac death, may be present in patients with ESRD without other evidence of coronary artery disease (CAD). We prospectively studied 131 patients who had rest and dipyridamole pharmacologic stress N(13)-ammonia positron emission tomography myocardial perfusion imaging (PET MPI) for kidney transplant evaluation...
