The aim of this paper is to define the productoperation on a family of interval valued events and the notion ofjoint interval valued observable. We show the connection betweenproduct operations for interval valued events and intuitionisticfuzzy events, too. We display the relatio
It Is Possible to Determine Exact Fuzzy Values Based on an Ordering of Interval-Valued Fuzzy Degrees
In the usual [0, 1]-based fuzzy logic, the actual numerical value of a fuzzy degree can be different depending on a scale, what is important – and scale-independent – is the order between different values. To make a description of fuzziness more adequate, it is reasonable to cons
Comparison of the prognostic value of cardiopulmonary exercise testing between male and female patients with heart failure.
BACKGROUND Cardiopulmonary exercise testing (CPX) clearly holds prognostic value in the heart failure (HF) population. Studies investigating the prognostic value of CPX in individuals with HF have consistently examined predominantly male groups. The purpose of the present study w
The prognostic value of normal stress cardiac magnetic resonance in patients with known or suspected coronary artery disease: a meta-analysis.
BACKGROUND Ischemia detection with stress cardiac magnetic resonance (CMR) is typically based on induction of either myocardial perfusion defect or wall motion abnormality. Single-center studies have shown the high value of stress CMR for risk stratification. The aim of this stud
The prognostic value of brain natriuretic peptide in patients with heart failure and left ventricular ejection fraction higher than 60%: a sub‐analysis of the J‐MELODIC study
AIMS Cardiac function varies in the population of patients with heart failure (HF) with preserved left ventricular ejection fraction (LVEF; HFpEF). This study investigated the heterogeneity of clinical features associated with HF and the prognostic value of BNP levels in patients
The Prognostic Value of Plasma Soluble ST2 in Hospitalized Chinese Patients with Heart Failure
BACKGROUND sST2 has been shown to be a risk predictor in heart failure (HF). Our aim was to explore the characteristics and prognostic value of soluble ST2 (sST2) in hospitalized Chinese patients with HF. METHODS AND RESULTS We consecutively enrolled 1528 hospitalized patients wi
The prognostic value of normal exercise myocardial perfusion imaging and exercise echocardiography: a meta-analysis.
OBJECTIVES The purpose of this work was to determine the prognostic value of normal exercise myocardial perfusion imaging (MPI) tests and exercise echocardiography tests, and to determine the prognostic value of these imaging modalities in women and men. BACKGROUND Exercise MPI a
Meta-analysis and systematic review of the predictive value of carotid plaque hemorrhage on cerebrovascular events by magnetic resonance imaging.
OBJECTIVES This study sought to conduct a systematic review and meta-analysis to determine precise estimates of the predictive value of carotid intraplaque hemorrhage (IPH) as determined by magnetic resonance imaging (MRI) for cerebrovascular events. BACKGROUND There is emerging
Influence of ejection fraction on the prognostic value of sympathetic innervation imaging with iodine-123 MIBG in heart failure.
OBJECTIVES The aim of this study was to determine whether left ventricular ejection fraction (LVEF) influences the relationship between abnormal myocardial sympathetic innervation imaging by iodine 123 meta-iodobenzylguanidine ((123)I-mIBG) and outcomes in patients with heart fai
Regression Model Fitting for the Interval Censored 1 Responses
In the interval censored case 1 data, an event occurrence time is unobservable, but one observes an inspection time and whether the event has occurred prior to this time or not. Such data is also known as the interval censored case 1 data. It is of interest to assess the effect o
