Key result
Chronic pressure overload hypertrophy, which produced a 40% increase in left ventricular mass, reduced coronary reserve and decreased endocardial capillary density compared to normal felines.
Why the study?
Does chronic pressure overload hypertrophy alter myocardial blood flow and capillary density in the feline left ventricle?
Does chronic pressure overload hypertrophy alter myocardial blood flow and capillary density in the feline left ventricle?
Chronic pressure overload hypertrophy results in an anatomical imbalance between capillary and myofiber growth, compromising endocardial flow reserve and increasing vulnerability to ischemia.
No takes yet. Share an insight, caveat, or question.
May heighten ischemic vulnerability in hypertrophied hearts; leaves open human translation of capillary rarefaction.
Breisch et al. (1980) studied Chronic pressure overload hypertrophy (n=14). 84% banding constriction of the ascending aorta vs. Normal felines (no banding) was evaluated on Myocardial blood flow, coronary reserve, and capillary density. Chronic pressure overload hypertrophy, which produced a 40% increase in left ventricular mass, reduced coronary reserve and decreased endocardial capillary density compared to normal felines.
