To obtain the normal ranges for 2D echocardiographic (2DE) indices of myocardial work (MW) from a large group of healthy volunteers over a wide range of ages and gender.
-up (mean, 20 (19) months), 11 patients developed symptoms but were not operated on, 57 required aortic valve replacement and six patients died. In multivariable Cox regression analysis, four parameters that were associated with the outcome were identified: peak aortic jet velocity, left ventricular systolic (LV) longitudinal deformation, valvulo-arterial impedance and indexed left atrial area. Using receiverÀoperator characteristic curve analysis, a peak aortic jet velocity $4.4 m/s, a LV longitudinal myocardial deformation #15.9%, a valvular-arterial impedance $4.9 mm Hg/ml per m 2 and an indexed left atrial area $12.2 cm
The expected growing volume of patients with cancer at risk of developing/worsening CV disease, the advent of new technological opportunities to refine diagnosis, and the necessity of early recognition of cancer therapy-related toxicity mandate an integrative multidisciplinary approach and care in a specialized environment. This document from the ESC Cardio-Oncology council proposes the grounds for creating C-O Services in Europe based on expert opinion.
The NORRE study provides contemporary, applicable 2D echocardiographic reference ranges for LV longitudinal, radial, and circumferential strain. Our data highlight the importance of age- and gender-specific reference values for LV strain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
