Plasma N-Terminal Pro-Brain Natriuretic Peptide as Prognostic Marker in Fatal Cardial Decompensation with Sunitinib Malate Therapy [PDF]
, 2010 A 74-year-old man with metastatic renal cell carcinoma and a history of cardiac failure was treated with sunitinib malate. MUGA echocardiography could not detect a relevant change in the ejection fraction although the clinical situation of the patient ...

Systolic phases of the cardiac cycle in children [PDF]
The American Journal of Cardiology, 1969 The duration of the systolic phases of the cardiac cycle in 390 normal children was determined from high-speed simultaneous recordings of the electrocardiogram, phonocardiogram, apexcardiogram, and carotid pulse. Data were obtained on children 1 mo to 13 years of age and analyzed to define the independent effects of aging and heart rate on the systolic

Single beat determination of intraventricular systolic dyssynchrony in paitents with atrial fibrillation and systolic dysfunction [PDF]
, 2013 Background:: Atrial fibrillation (AF) is the most common clinically significant cardiac arrhythmia. However, diagnosis of intraventricular dyssynchrony in patients with AF is difficult due to beat-to-beat variation. Additionally, evaluation of mechanical

Automated Segmentation on the Entire Cardiac Cycle Using a Deep Learning Work - Flow [PDF]
International Conference on Social Networks Analysis, Management and Security, 2018 The segmentation of the left ventricle (LV) from CINE MRI images is essential to infer important clinical parameters. Typically, machine learning algorithms for automated LV segmentation use annotated contours from only two cardiac phases, diastole, and ...

Synchronization of Wave Flows of Arterial and Venous Blood and Phases of the Cardiac Cycle: Part 3 [PDF]
International Journal of Biomedicine, 2018 Hemodynamic indices studied in healthy people were obtained by catheterization in various vascular areas: the chambers of the heart (ventricles, atria, coronary sinus), pulmonary trunk, sigmoid sinus, aorta, inferior vena cava, superior vena cava (SVC ...

Cardiac Progenitors and the Embryonic Cell Cycle [PDF]
Cell Cycle, 2007 Despite the critical importance of proper cell cycle regulation in establishing the correct morphology of organs and tissues during development, relatively little is known about how cell proliferation is regulated in a tissue-specific manner. The control of cell proliferation within the developing heart is of considerable interest, given the high ...

Cyclic changes of blood echogenicity in high-frequency ultrasound [PDF]
, 1991 Ultrasound images from human arteries obtained in vivo with an intravascular 30 MHz ultrasound imaging device show that blood echogenicity changes during the cardiac cycle.
