Increase in cardiac contractility during puberty.
Pubertal growth of heart was analyzed. Growth rates of "diastolic variables" of heart size were compared with that of 'systolic', and both with growth intensities of some body structures and functions that are related to cardiac growth. Longitudinal echocardiographic, ergometric and anthropometric measurements were performed in 84 healthy boys, aged 11.5 years at the beginning and 14.5 at the e...
متن کاملCardiac contractility modulation therapy: Are there superresponders?
Introduction Heart failure (HF) is a common cardiovascular disease, and it is associated with high morbidity and mortality despite advances in medical and device-related management. Patients with HF with low left ventricular ejection fraction (LVEF) and narrow QRS complexes represent a special challenge, as they are not candidates for cardiac resynchronization therapy (CRT). These patients may ...
متن کاملSES differences in language processing skill and vocabulary are evident at 18 months.
This research revealed both similarities and striking differences in early language proficiency among infants from a broad range of advantaged and disadvantaged families. English-learning infants (n = 48) were followed longitudinally from 18 to 24 months, using real-time measures of spoken language processing. The first goal was to track developmental changes in processing efficiency in relatio...
متن کاملAge-dependent differences in microglial responses to systemic inflammation are evident as early as middle age.
Whereas age increases microglial inflammatory activities and impairs their ability to effectively regulate their immune response, it is unclear at what age these exaggerated responses begin. We tested the hypotheses that augmented microglial responses to inflammatory challenge are present as early as middle age and that repeated stimulation of primed microglia in vivo would reveal microglial se...
متن کاملCardiac work and contractility.
It has been customary to regard the heart as a pump maintaining the flow of blood, and to assess the work done by the heart from the pressure and volume of blood leaving the ventricles. While correct in physical terms, measurement of external cardiac work in this way is a poor index of the myocardial oxygen consumption which is related to the work done by the ventricular muscle. Systolic pressu...
