During isometric contractions, slow twitch soleus muscles (SOL) from rats with chronic heart failure (chf) are more fatigable than those of sham animals. However, a muscle normally shortens during activity and fatigue development is highly task depen

The reduced power of the failing heart can be ascribed to a combination of reduced force and slower contraction. We hypothesized that these two properties are due to different cellular mechanisms. We measured contraction parameters both in vivo and i

The Na+/K+-ATPase (NKA) alpha2-isoform is preferentially located in the t-tubules of cardiomyocytes and is functionally coupled to the Na+/Ca(+-exchanger (NCX) and Ca2+ regulation through intracellular Na+ concentration ([Na+]i). We hypothesized that

Background and purpose: Positive inotropic responses (PIR) to 5-hydroxytryptamine (5-HT) are induced in the left ventricle (LV) in rats with congestive heart failure (CHF); this is associated with upregulation of the Gs-coupled 5-HT4 receptor. We inv

Background : Current pharmacological treatment of congestive heart failure (CHF) addresses changes in neurohumoral stimulation or cardiac responsiveness to such stimulation. Yet, undiscovered neurohumoral changes, adaptive or maladaptive, may occur i

A positive inotropic responsiveness to serotonin, mediated by 5-HT(4) and 5-HT(2A) receptors, appears in the ventricle of rats with post-infarction congestive heart failure (HF) and pressure overload-induced hypertrophy. A hallmark of HF is a transit

The sarco(endo)plasmic reticulum calcium ATPase 2 (SERCA2) transports Ca(2+) from cytosol into the sarcoplasmic reticulum (SR) of cardiomyocytes, thereby maintaining the store of releasable Ca(2+) necessary for contraction. Reduced SERCA function has

Background and purpose: Muscarinic stimulation increases myofilament Ca2+ sensitivity with no apparent inotropic response in normal rat myocardium. Increased myofilament Ca2+ sensitivity is a molecular mechanism promoting increased contractility in f

Rats with congestive heart failure (CHF) develop ventricular inotropic responsiveness to serotonin (5-HT), mediated through 5-HT2A and 5-HT4 receptors. Human ventricle is similarly responsive to 5-HT through 5-HT4 receptors. We studied isolated ventr
