In 50 patients with proven acute myocardial infarction (AMI), left ventricular hemodynamics (pulmonary end-diastolic pressure [PAEDP]; cardiac index [CI]; stroke volume index [SVI]; and SVI/PAEDP were related to the size of the acute infarct. Acute infarct mass was calculated from serial determinations of serum creatine phosphokinase (CPK) every two hours, using a computer program. In 15 cases ...

PURPOSE To prospectively determine, for both digital subtraction angiography (DSA) and contrast material-enhanced magnetic resonance (MR) angiography, the accuracy of subjective visual impression (SVI) in the evaluation of internal carotid artery (ICA) stenosis, with objective caliper measurements serving as the reference standard. MATERIALS AND METHODS Local ethics committee approval and wri...

AIMS Reduced stroke volume index (SVI) in patients with severe aortic stenosis (AS) and preserved ejection fraction (EF) is associated with adverse outcomes even after aortic valve replacement (AVR), although specific reasons for impaired survival in this group are unknown. We investigated predictors of post-AVR survival and specific cause of death in patients with AS according to SVI. METHOD...

PURPOSE Estimates of the incidences of severe visual impairment and blindness (SVI/B) and their causes are key to good health service planning. Thus, the database of Germany's largest state's blind registry was used to estimate current incidence rates (IR) and to project rates for Germany in 2010 and 2030. METHODS The sample consisted of 3328 blind/severely visually impaired individuals newly...

BACKGROUND Although cardiovascular (CV) risks are reported in first-degree relatives (FDRs) of type 2 diabetics, effects of gender on sympathovagal imbalance (SVI) and CV risks in these subjects have not been investigated. METHODS Body mass index (BMI), blood pressure variability parameters including baroreflex sensitivity (BRS), spectral indices of heart rate variability, autonomic function ...

OBJECTIVES The goal of this study was to assess the prognostic power of the pulse pressure-to-stroke index (PP-to-SVi) ratio for cardiovascular events and mortality in patients with uncomplicated hypertension. BACKGROUND The prognostic significance of pulse pressure (PP) has been studied repeatedly, but few data are available on the PP-to-SVi ratio. METHODS Invasive hemodynamic measurements...

OBJECTIVES Capillary refill time is an important diagnostic adjunct in the acute resuscitation phase of the shocked child. This study assesses its relation to commonly measured haemodynamic parameters in the postresuscitation phase when the child has reached the intensive care unit, and compares this with core-peripheral temperature gap. METHODS Ninety standardised measurements of capillary r...

A 2-step clustering procedure, using indexes derived from principal component analysis, was used to disclose sperm subpopulations within the canine ejaculate and its relationship to sperm cryoresistance. Semen from 4 dogs was frozen-thawed by a standard protocol: before freezing, computer-assisted sperm analysis of motility and morphometry were performed; after thawing, motility analysis was pe...

PURPOSE This study is a review of the major causes of visual impairment (VI) and severe visual impairment/blindness (SVI/BL) in Mount Popa Taung-Kalat, a rural region in Myanmar (Burma). METHODS A review of our clinical records of consecutive patients attending clinics was conducted. Participants of all ages (n = 650) of the population of Mount Popa Taung-Kalat and villages in its vicinity un...

INTRODUCTION Plethysmographic Variability Index (PVI) has been shown to accurately predict responsiveness to fluid loads in adults. The goal of this study was to evaluate PVI accuracy when predicting fluid responsiveness during noncardiac surgery in children. MATERIAL AND METHODS Children aged 2-10 years scheduled for noncardiac surgery under general anesthesia were included. PVI was assessed...
