Background—Little research has been conducted on the predictors of self-report or patient awareness of heart failure (HF) in a population-based survey. The objective of this study was to (1) test the agreement between Medicare administrative and Health and Retirement Study (HRS) survey data and (2) determine predictors associated with self-report of HF, using a validated Medicare claims algorit...

AIMS To examine relationships between cardiac troponin T (cTnT) and parameters of left ventricular (LV) structure and function in patients with acute destabilized heart failure (HF) with preserved LV ejection fraction. METHODS AND RESULTS In 44 patients with acute heart failure (HF) with preserved left ventricular (LV) ejection fraction, parameters of LV structure and function were assessed v...

BACKGROUND The aim of our study was to evaluate in stable outpatients with systolic heart failure (HF) the 3 months effect of ivabradine on LV synchronization and Tei index in stable outpatients with systolic HF. METHODS We evaluated prospectively 40 (30 males, 10 females) patients with HF. All patients were evaluated before and after treatment by transthoracic M mode, two dimensional (2D), p...

Wave energy resource assessment is crucial for the development of marine renewable industry. High-frequency radars (HF radars) have been demonstrated to be a useful wave measuring tool. Therefore, in this work, we evaluated accuracy two CODAR Seasonde HF describing offshore areas west Galician coast, Spain (Vilán and Silleiro capes). The resulting characterization was used estimate electricity ...

HF radar backscatter which has been artificiallyinduced by a high power RF facility such as the EISCAT heater at Tromsø has been demonstrated to provide ionospheric electric field data of unprecedented temporal resolution and accuracy. Here such data are used to investigate ULF wave processes observed by the CUTLASS HF radars. Within a short period of time during a single four hour experiment t...
