Description
Miki Hirose and co-authors measured an inner-heart pressure index in cats with hypertrophic cardiomyopathy, a common feline heart disease. The index, computed from ultrasound motion tracings and adjusted for heart length, reflects how well the heart relaxes. The team compared ten healthy cats with eighteen cats whose disease blocked the outflow path.
Even without severe enlargement of the upper chamber, the blocked group showed a clearly higher index in the heart's base segment. Normally a high value signals poor relaxation, but here the authors read it as an indirect sign of raised pressure in the upper chamber, caused by the outflow blockage. They say the index reveals a side of the disease that standard ultrasound measures miss.
