OBJECTIVES We tested the prognostic value of a new electrocardiographic (ECG) method (Perugia score) for diagnosis of left ventricular hypertrophy (LVH) in essential hypertension and compared it with five standard methods (Cornell voltage, Framingham criterion, Romhilt-Estes point score, left ventricular strain, Sokolow-Lyon voltage). BACKGROUND Several standard ECG methods for assessment of ...

OBJECTIVE Left ventricular hypertrophy (LVH) is an independent predictor of cardiovascular (CV) mortality. This study compared different criteria including Sokolow-Lyon and Cornell, in terms of voltage and voltage-QRS-duration products, as well as point-scoring systems such as the Romhilt-Estes, Perugia and Glasgow-Royal-Infirmary modified Romhilt-Estes score. METHODS Patients undergoing echo...

Existe grande interesse no estudo de heterodímeros constituídos por metaloporfirinas e ftalocianinas de carga oposta, uma vez que estes sistemas são modelos do special pair da fotossíntese e dispositivos moleculares promissores para a transferência de elétrons unidirecional. Neste trabalho foram sintetizadas novas metaloporfirinas catiônicas, e investigada a formação de heteroagregados com meta...

W.K. Estes often championed an approach to model development whereby an existing model was augmented by the addition of one or more free parameters to account for additional psychological mechanisms. Following this same approach we utilized Estes’ (1950) own augmented learning equations to improve the plausibility of a win-stay-lose-shift (WSLS) model that we have used in much of our recent wor...

Strategies for managing chronic wasting disease (CWD) in urban mule deer (Odocoileus hemionus) populations are needed in Colorado. We captured, tonsil-biopsied, marked, and tested adult mule deer (n=181) to evaluate the feasibility of conducting an urban "test-and-cull" program in Estes Park, Colorado. During December 2002 and April-May 2003, we successfully tested 51 (57O/%) of the estimated 8...

BACKGROUND Left ventricular hypertrophy (LVH) is a hallmark of chronic pressure or volume overload of the left ventricle and is associated with risk of cardiovascular morbidity and mortality. The purpose was to evaluate different electrocardiographic criteria for LVH as determined by cardiovascular magnetic resonance (CMR). Additionally, the effects of concentric and eccentric LVH on depolariza...

W.K. Estes often championed an approach to model development whereby an existing model was augmented by the addition of one or more free parameters, and a comparison between the simple and more complex, augmented model determined whether the additions were justified. Following this same approach we utilized Estes' (1950) own augmented learning equations to improve the fit and plausibility of a ...
