Renin-angiotensin blockade combined with natriuretic peptide system augmentation: novel therapeutic concepts to combat heart failure.
Cardiovascular diseases in general and heart failure (HF) in particular are major contributors to death and morbidity in the Western world, where they are also recognized as important drivers of… Expand
Does indoxyl sulfate, a uraemic toxin, have direct effects on cardiac fibroblasts and myocytes?
- S. Lekawanvijit, A. Adrahtas, D. Kelly, A. Kompa, B. Wang, H. Krum
- European heart journal
- 4 January 2010
AIMS Indoxyl sulfate (IS) is a uraemic toxin found at high concentration in patients with chronic kidney disease (CKD) co-morbid with chronic heart failure (CHF). The aim of this study was to… Expand
Microglia activation in the hypothalamic PVN following myocardial infarction
Following a myocardial infarction (MI), inflammatory cytokines are elevated in the brain, as well as in plasma, indicating that inflammation is occurring in the brain in addition to the periphery.… Expand
Angiotensin Receptor Neprilysin Inhibitor LCZ696 Attenuates Cardiac Remodeling and Dysfunction After Myocardial Infarction by Reducing Cardiac Fibrosis and Hypertrophy
Background—Angiotensin receptor neprilysin inhibitors (ARNi), beyond blocking angiotensin II signaling, augment natriuretic peptides by inhibiting their breakdown by neprilysin. The myocardial… Expand
Cardiac Tissue Engineering in an In Vivo Vascularized Chamber
Background— Cardiac tissue engineering offers the prospect of a novel treatment for acquired or congenital heart defects. We have created vascularized pieces of beating cardiac muscle in the rat that… Expand
Differential Effect of Urotensin II on Vascular Tone in Normal Subjects and Patients With Chronic Heart Failure
- M. Lim, S. Honisett, Christopher D Sparkes, P. Komesaroff, A. Kompa, H. Krum
- 16 March 2004
Background—Urotensin II (U-II) is a novel vasoactive peptide that also has direct hypertrophic and profibrotic effects on the myocardium. Upregulation of U-II and its receptor has been observed… Expand
Inotropic responses to human gene 2 (B29) relaxin in a rat model of myocardial infarction (MI): effect of pertussis toxin
Relaxin produces powerful inotropic and chronotropic responses in isolated atria. The effect of relaxin has been examined in a rat model of cardiac failure, induced by myocardial infarction (MI).… Expand
Desensitization of cardiac beta-adrenoceptor signaling with heart failure produced by myocardial infarction in the rat. Evidence for the role of Gi but not Gs or phosphorylating proteins.
- A. Kompa, X. Gu, B. A. Evans, R. Summers
- Journal of molecular and cellular cardiology
- 1 June 1999
This study examined mechanisms of beta-adrenergic (AR) desensitization in a myocardial infarction (MI) model of heart failure in the rat. Inotropic responses to isoproterenol (non-selective beta-AR… Expand
Soluble epoxide hydrolase inhibition exerts beneficial anti-remodeling actions post-myocardial infarction.
BACKGROUND A contributory role for soluble epoxide hydrolase (sEH) in cardiac remodeling post-myocardial infarction (MI) has been suggested; however effects of sEH inhibition following MI have not… Expand
Cardiorenal Syndrome: The Emerging Role of Protein-Bound Uremic Toxins
