... stiffness than the longer N2BA isoform. We hypothesised that the expression of the short N2B isoform would be increased in patients with aortic stenosis compared with healthy controls in response to pressure overload, in order to act as a modulator for the increased demand placed on the left ventricle...

... of degenerative AS (aortic stenosis). We enrolled 30 patients (16 males; age, 61.3±8.2 years) diagnosed with degenerative AS and an additional 30 age- and sex-matched control patients. Invasive PWV methods with a pigtail catheter and double-channel recording were performed in both groups in our catheterization...

...A. Stella; F. Calaresu; A. Zanchetti 1. Renin release from an intact, innervated kidney and from the contralateral denervated kidney was measured before and during a period of suprarenal aortic stenosis. 2. Aortic stenosis of 10 min duration reduced renal perfusion pressure to 50 mmHg and increased...

.... Suprarenal aortic stenosis of 10 min duration reduced renal perfusion pressure to 50 mmHg and halved blood flow to both kidneys, but caused a greater release of renin from the innervated kidney than from the contralateral denervated one (increments of 72 ± 17 and 29 ± 20 pmol/min respectively). 3. A study...

... change has been established. 4. The effect of diuretics on renin release has been studied and evidence of neural and non-neural mechanisms obtained. 5. The effect of suprarenal aortic stenosis has been studied; the findings suggest that renin release is in some way dependent on neural mechanisms. 6...
