Does reciprocal ST-segment depression associated with exercise-induced ST-segment elevation indicate residual viability after myocardial infarction?
The occurrence of reciprocal ST-segment depression associated with exercise-induced ST segment elevation in patients with a previous Q-wave infarction who had single-vessel disease indicates residual tissue viability within the infarct-related area.
Pressure loading of the fetal sheep heart leads to developmentally regulated cell signaling profiles. ERK and possibly Akt may be important regulators of in vivo cardiomyocyte hyperplasia.
