AimsMaximal hyperaemia is a key element of invasive physiological studies and adenosine the most commonly used agent. However, infusion requires additional venous access can cause chest discomfort, bronchial hyper-reactivity, atrioventricular conduction block. The aim this study was to evaluate feasibility efficacy intracoronary (IC) nicorandil as novel hyperaemic agent for studies.
To examine physiological and clinical relevance of an anomalous right coronary artery originating from left sinus Valsalva (right ACAOS) with interarterial course in adults.For assessment, fractional flow reserve (FFR) during dobutamine challenge was measured 37 consecutive adult patients lone ACAOS course. At baseline, mean FFR 0.91±0.06, declining to 0.89±0.06 upon infusion (p<0.001). Dobutamine stress significant (≤0.8) three (8.1%), two whom were surgically treated. Following surgery,...
Effortful swallowing (EFS) is a common compensatory manoeuver for dysphagia patients. We investigated the influence of EFS on temporal and spatial characteristics movements hyoid bone, larynx epiglottis in healthy subjects. A total 41 volunteers swallowed 10 mL diluted barium solution using two strategies: usual effortful (USS EFS). The motions were tracked frame-by-frame kinematic motion analysis videofluoroscopic images. Maximal velocities maximal displacements larynx, angle epiglottic...
Background— The aim of this study was to assess whether deferred stenting (DS) reduces infarct size and microvascular obstruction (MVO) compared with immediate (IS) in primary percutaneous coronary intervention for ST-segment–elevation myocardial infarction. Methods Results— From February 2013 August 2015, 114 patients (mean age: 69 years) were randomized into the following 2 groups: DS an intention stent 3 7 days later or IS after reperfusion centers. secondary end points incidence MVO,...
Abstract Scores of the performance scale Wechsler Adult Intelligence Scale (WAIS) declined linearly with age from 6th decade, whereas those verbal did not. This decrease in intelligence was thought to be related an age‐related frontal atrophy. The relationship between scores WAIS and changes regional cortical gray matter density were examined healthy elderly subjects using voxel‐based morphometry. Thirty non‐demented individuals >50 years tested scanned brain magnetic resonance imaging...
Background and Objectives: Numbness on the hand occurs infrequently after a transradial cardiac catheterization (TRC).The symptom resembles that of neuropathy.We, therefore, investigated prevalence, predicting factors presence neurological abnormalities numbness, using nerve conduction study (NCS).Subjects Methods: From April to December 2013, all patients who underwent TRC were prospectively enrolled.From among these, experienced numbness ipsilateral instructed describe their symptoms...
Serum alkaline phosphatase (ALP) has been shown to be a prognostic factor in several subgroups of patients due its promotion vascular calcification. However, the impact serum ALP level ST-segment elevation myocardial infarction (STEMI) with relatively low calcification burden not determined. We aimed investigate association measured at time presentation on clinical outcomes STEMI requiring primary percutaneous coronary intervention (PCI).A total 1178 undergoing PCI between 2007 and 2014 were...
Background Besides contrast-induced acute kidney injury(CI-AKI), adscititious vital organ damage such as hypoxic liver injury(HLI) may affect the survival in patients with ST-elevation myocardial infarction (STEMI). We sought to evaluate prognostic impact of CI-AKI and HLI STEMI who underwent primary percutaneous coronary intervention (PCI). Methods A total 668 consecutive (77.2% male, mean age 61.3±13.3 years) from INTERSTELLAR registry PCI were analyzed. was defined an increase ≥0.5 mg/dL...
Background Elevated serum transaminase or alkaline phosphatase (ALP) has been proposed as a novel prognosticator for ST-segment elevation myocardial infarction (STEMI). We evaluated the combined prognostic impact of elevated transaminases and ALP on admission in STEMI patients who underwent primary percutaneous coronary intervention (PCI). Methods A total 1176 with undergoing PCI were retrospectively enrolled from INTERSTELLAR registry. Hypoxic liver injury (HLI) was defined > twice upper...
Background: The frequency of using veno-arterial extracorporeal membrane oxygenation increased, especially in patients with refractory cardiogenic shock or cardiac arrest. However, data complications are lacking. This study sought to investigate the incidence for acute myocardial infarction arrest and its relationship patient survival. Methods: included 151 consecutive who underwent between 2006 2018 at a single referral center. We divided into those survived 30 days after ( n = 57, 38%;...
The clinical value of residual quantitative flow ratio (rQFR), a novel function QFR technique, is unknown.We investigated the rQFR, aimed to predict ischemia after virtual percutaneous coronary intervention (vPCI).This substudy COE-PERSPECTIVE registry, which prognostic post-PCI fractional reserve (FFR). From pre-PCI angiograms, and rQFR were analyzed their diagnostic performance was assessed at blinded fashion using FFR as reference, respectively. vPCI according vessel-oriented composite...
We sought to evaluate the impact of final kissing balloon inflation (FKBI) after simple stent implantation for treatment non-left main true coronary bifurcation lesions in patients with acute syndrome (ACS).Whether FKBI should be mandatory lesion is controversial. Besides, ACS who have undergone percutaneous intervention may experience worse prognosis compared stable angina pectoris patients.Two hundred and fifty one eligible (67.7% male, mean age 61.7 ± 10.4 years) were enrolled. The study...
Increased adrenergic tone might be an additional trigger of orthostatic stress vasovagal syncope (VVS). Exercise before standing provide increased sensitivity compared to using a sublingual nitroglycerines protocol during tilt table testing. The aim this study was evaluate the diagnostic value treadmill testing with nitroglycerin administration.A total 36 patients or presyncope were enrolled for test. VVS confirmed in 29 according Calgary Score (≥ -2), including 20 who likely have typical...
Abstract Background Several biomarkers have been proposed as independent predictors of poor outcomes in ST-segment elevation myocardial infarction (STEMI). We investigated whether adding information obtained from routine blood tests including hypoxic liver injury (HLI), dysglycemia, anemia, and high neutrophil to lymphocyte ratio (NLR) could improve the prognostic performance TIMI risk score for prediction 1-year mortality. Methods A total 1057 patients with STEMI undergoing primary...
We present PICCOLO, a simple and efficient algorithm for omnidirectional localization. Given colored point cloud 360 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">˝</sup> panorama image of scene, our objective is to recover the camera pose at which taken. Our pipeline works in an off-the-shelf manner with single given as query does not require any training neural networks or collecting ground-truth poses images. Instead, we match each color...
Purpose: Kilt technique can be useful for overcoming the severe angle in endovascular abdominal aortic repair. Thus, we investigate utility of as an modification method.
