Intrauterine Growth Restriction Influences Vascular Remodeling and Stiffening in the Weanling Rat More than Sex or Diet

Intrauterine growth restriction (IUGR) increases the incidence of adult cardiovascular disease (CVD). The sex-specific developmental mechanisms for IUGR-induced and western high fat diet (HFD) modification of CVD remain poorly understood. We hypothesized a maternal HFD in the Sprague-Dawley rat would augment IUGR-induced CVD in the offspring through decreased cardiac function and increased extracellular matrix (ECM) remodeling and stiffness in a sex-specific manner.

Preconditioning of the Heart Following Transmyocardial Revascularization

Transmyocardial Laser Revascularization (TMR) is an approved treatment of end stage coronary artery disease. Explanation on how TMR improves symptoms is currently unknown although myocardial angiogenesis and denervation are considered as possible mechanisms.
