pressure overload

Demand placed on muscle, esp. heart muscle, in response to high blood pressure or stenotic valves. Over time pressure overload results in cardiac hypertrophy and, eventually, heart failure.

In the present study, protein expressions of MMP-2 and MMP-9 were significantly elevated in the hearts exposed to pressure overload and this elevation was attenuated by angoroside C.
In our present study, angoroside C could decrease serum Ang II concentration, suppress TGF-[beta]1 mRNA and ET-1 mRNA expression, attenuate collagen deposition, reduce the fibrosis, block ventricular remodeling in the pressure overload model rats.
Absence of pressure overload induced myocardial hypertrophy after conditional inactivation of Gaq/Gall in cardiomyocytes.
While noradrenaline was found to increase PVR in chronic PHT (133), it reduced (74,133) or did not alter PVR (134) in acute RV failure due to pressure overload.
Dobutamine is useful in the management of RV failure due to acute pressure overload as it increases RV contractility without affecting PVR (146).
Logistic regression analysis was performed to determine the independent predictors of chronic pressure overload.
03) were found to be the independent predictors of chronic RV pressure overload.
EGCG attenuates cardiac fibrosis from pressure overload
In the present work, we revealed that EGCG attenuated cardiac fibrosis induced by Angll treatment or pressure overload induced by AAC, which might be mediated by suppressing CTGF expression.
Additionally, study observations showed that patients experienced a 158 +/- 289 pg/dl drop in B-type natriuretic peptide (BNP) levels, a protein secreted by the heart when under volume or pressure overload.
