Are midwall mechanics improved after regression of hypertensive left ventricular hypertrophy and normalization of chamber geometry?
Regression of concentric LVH is associated with an improvement of midwall systolic function, which is more dependent on the normalization of LV geometry than on the reduction in LV systolic stress.
Our results show that measures of the patient's clinical presentation account for nearly one third of the variability that our model explains. This suggests that differences in clinical presentation and severity of illness underlie much of the observed practice variability among pediatricians evaluating and treating febrile infants. These findings demonstrate that the management of this common and potentially serious condition depends more on the clinical presentation of the patient than on the characteristics of the provider/practice and the residential region.
