Diastolic function: a barometer for cardiovascular risk?
PERIOPERATIVE cardiovascular risk assessment has undergone significant advances, including development and validation of multivariable risk indices for prediction of major cardiac complications, advances in detecting ischemic heart disease, and noninvasive detection of symptomatic reductions in left ventricular (LV) ejection fraction. However, we have recently recognized that current preoperati...
متن کاملEndothelial function: a barometer for cardiovascular risk?
The endothelium regulates vascular homeostasis by elaborating a variety of paracrine factors that act locally in the blood vessel wall and lumen.1 Under normal conditions, the sum total effect of these endothelial factors is to maintain normal vascular tone, blood fluidity, and limit vascular inflammation and smooth muscle cell proliferation. However, when coronary risk factors are present, the...
متن کاملThe thymus: a barometer of malnutrition.
In 1810 J. F. Menkel noted that the human thymus was especially sensitive to malnutrition (see Jackson, 1925; Beisel, 1992), and the term ‘nutritional thymectomy’ came into common usage. By 1845 Simon (1845) had observed that the thymus is ‘a barometer of malnutrition, and a very sensitive one’. These observations were made over a century before the role of the thymus in lymphocyte development ...
متن کاملFall Detection Using a Head-Worn Barometer
Falls are a significant health and social problem for older adults and their relatives. In this paper we study the use of a barometer placed at the user’s head (e.g., embedded in a pair of glasses) as a means to improve current wearable sensor-based fall detection methods. This approach proves useful to reliably detect falls even if the acceleration produced during the impact is relatively smal...
