Reduction in Myocardial Collagen Cross-Linking Parallels Left Ventricular Dilatation in Rat Models of Systolic Chamber Dysfunction

TL;DR: Reductions in myocardial collagen cross-linking may be an important mechanism contributing to LV dilatation in heart disease.
Journal ArticleDOI

Myocardial Stiffness Is Attributed to Alterations in Cross-Linked Collagen Rather Than Total Collagen or Phenotypes in Spontaneously Hypertensive Rats

TL;DR: An association between alterations in LVED k and collagen solubility but not between changes in LV ED k and total collagen or phenotype ratios after antihypertensive therapy in SHRs suggests that myocardial stiffness in hypertension is the consequence of an enhanced myocardian collagen cross-linking rather than of an increase in total collagen and type I phenotype concentrations.
Journal ArticleDOI

Aminoguanidine Prevents the Decreased Myocardial Compliance Produced by Streptozotocin-Induced Diabetes Mellitus in Rats

TL;DR: It is demonstrated that diabetes mellitus can produce a stiff myocardium before the development of myocardial fibrosis and in these circumstances is associated with the formation of collagen AGEs.
Journal ArticleDOI

Obesity promotes left ventricular concentric rather than eccentric geometric remodeling and hypertrophy independent of blood pressure.

TL;DR: In a population sample with a high prevalence of obesity, excess adiposity promotes concentric, rather than eccentric LV geometric changes, effects which are independent of conventional, central artery or 24-h BP measured on a single occasion.
