Assessment of myocardial injury after reperfused infarction by T1ρ cardiovascular magnetic resonance.

Background: The evolution of T1ρ and of other endogenous contrast methods (T2, T1) in the first month after reperfused myocardial infarction (MI) is uncertain. We conducted a study of reperfused MI in pigs to serially monitor T1ρ, T2 and T1 relaxation, scar size and transmurality at 1 and 4 weeks post-MI.

Methods: Ten Yorkshire swine underwent 90 min of occlusion of the circumflex artery and reperfusion.

Is the OSA-18 predictive of obstructive sleep apnea: comparison to polysomnography.

Objectives/hypothesis: To examine the ability of the OSA-18 to predict Obstructive Sleep Apnea (OSA) in a racially diverse population when compared to overnight polysomnography (PSG).

Study Design: Cross-sectional retrospective.

Methods: Children 2 to 12 years of age diagnosed with OSA who were treated at a tertiary care institution between 2008 and 2013 and had complete PSG and OSA-18 data were included.
