Key result
A 10-minute period of anoxia in hypertrophied rat hearts caused an exaggerated decrease in left ventricular diastolic chamber distensibility and increased coronary vascular resistance compared to controls.
Why the study?
Does a brief period of anoxia cause exaggerated changes in ventricular diastolic compliance and coronary vascular resistance in rat models of hypertension compared to controls?
Does a brief period of anoxia cause exaggerated changes in ventricular diastolic compliance and coronary vascular resistance in rat models of hypertension compared to controls?
Anoxia induces an exaggerated increase in myocardial stiffness in hypertrophied hearts, which limits coronary flow.
No takes yet. Share an insight, caveat, or question.
Should not change clinical practice in hypertension; leaves open whether anoxia exacerbates diastolic stiffness in human hypertrophied hearts.
Amrani et al. (1992) studied Left ventricular hypertrophy / Hypertension. 10-min period of anoxia vs. Control (non-hypertrophied) hearts was evaluated on Left ventricular diastolic chamber distensibility and coronary vascular resistance. A 10-minute period of anoxia in hypertrophied rat hearts caused an exaggerated decrease in left ventricular diastolic chamber distensibility and increased coronary vascular resistance compared to controls.
