Reactive oxygen species partially mediate high dose angiotensin II-induced positive inotropic effect in cat ventricular myocytes
(Elsevier Science Inc, 2015-07)
Background: Reactive oxygen species, such as superoxide, are being increasingly recognized as key components of a vast array of signaling pathways. Angiotensin II is a well-recognized stimulus for superoxide production ...
Functional beta(2)-adrenoceptors in rat left atria: effect of foot-shock stress
(Canadian Science Publishing, Nrc Research Press, 2017)
Altered sensitivity to the chronotropic effect of catecholamines and a reduction in the beta(1)/beta(2)-adrenoceptor ratio have previously been reported in right atria of stressed rats, human failing heart, and aging. In ...
Negative inotropic and chronotropic effects on the guinea pig atrium of extracts obtained from Averrhoa carambola L. leaves
(Associação Brasileira de Divulgação Científica, 2016)
The effect of harmaline on force of contraction of the rat isolated atrium
(1975)
In rat isolated right atria, beating spontaneously at 30°C, harmaline 8.3 × 10-5 M slowed atrial rate and enhanced force of contraction. The velocity of development of tension (dT/dt) increased and time to peak tension was ...
Decreased inotropic response to beta-adrenergic stimulation in hypertrophied cardiac muscle from pressure-overloaded hearts
(Federation Amer Soc Exp Biol, 2014)
End-systolic pressure-diameter relation of the left ventricle during transient and sustained elevations of blood pressure
(Sociedade Brasileira de Cardiologia (SBC), 2000-07-01)
OBJECTIVE: To assess the effect of transient and sustained variations in cardiac load on the values of the end-systolic pressure-diameter relation (ESPDR) of the left ventricle. METHODS: We studied 13 dogs under general ...

Neuromuscular electrical stimulation improves exercise tolerance in patients with advanced heart failure on continuous intravenous inotropic support userandomized controlled trial
(Sage Publications Ltd, 2018)
Objective:
To evaluate the impact of a short-term neuromuscular electrical stimulation program on exercise tolerance in hospitalized patients with advanced heart failure who have suffered an acute decompensation and are ...
