BACKGROUND AND PURPOSE Specialized stroke unit care improves outcome among patients with stroke, but it is unclear whether there are any scale advantages in costs and clinical outcome from treating a larger number of patients. We examined whether the case volume in stroke units was associated with quality of early stroke care, mortality, and hospital bed-day use. METHODS In a nationwide popul...

Studies have demonstrated that optimising the circulating volume reduces morbidity after major surgery. This optimisation is usually achieved through maximisation of the stroke volume guided by oesophageal Doppler. New monitoring parameters of preload responsiveness using information from the arterial trace are now showing some promise in achieving the same goal. The present commentary examines...

Echocardiographic study was performed in ten patients with accidental hypothermia to investigate the hypothermic effects on cardiac activities. The intervals from the onset of the posterior wall forward movement to the peak of the forward excursion (C-D interval) and from the peak of the forward excursion to the end of the early diastolic filling (D-F interval) were pro longed in hypothermia. T...

The pressure gradient technique was used to evaluate effects of respiration on left ventricular stroke volume in 22 patients: 11 normal patients; eight patients with airway obstruction; and three patients with pericardial tamponade. In normals, stroke volume, systolic pressure, and pulse pressure fell an average of 7, 3 and 11% (P < 0.01), respectively, during inspiration. In patients with airw...

introduction: black pepper (piper nigrum l.) is one of the medicinal plants being used to prevent and manage stroke in persian medicine. current findings support its anti-inflammatory, radical scavenging and neuroprotective characteristics. in this study, we aimed to evaluate role of black pepper on functional and histopathological outcomes of stroke in an animal model of mcao. materials and me...

INTRODUCTION Cardiac output increases during incremental-load exercise to meet metabolic skeletal muscle demand. This response requires a fast adjustment in heart rate and stroke volume. The heart rate is well known to increase linearly with exercise load; however, data for stroke volume during incremental-load exercise are unclear. Our objectives were to (a) review studies that have investigat...
