BACKGROUND: Experimental studies support a key role for cytokines in left ventricular remodeling. In congestive heart failure (CHF) patients, elevated plasma cytokine levels are associated with worse functional status and adverse prognosis. It is unclear whether cytokine levels can predict the incidence of CHF in asymptomatic individuals. METHODS AND RESULTS: ...

Evaluation of myocardial iron during iron chelation therapy is not feasible by repeated endomyocardial biopsies owing to the heterogeneity of iron distribution and the risk of complications. Recently, we described a noninvasive method based on magnetic resonance imaging. Here, the method was used for repeated estimation of the myocardial iron ...

Epileptic patients receiving medications such as phenytoin or phenobarbital have been noted to have an exceedingly low incidence of myocardial infarction, but children treated with carbamazepine have shown alteration of their serum lipid profile that could predispose them to atherosclerosis. This report seems to corroborate this point and describes the ...

BACKGROUND: Mast cells are prevalent in the shoulder of unstable atheromas; cardiac mast cells secrete proteases capable of activating matrix metalloproteinases. Histamine is essential in the inflammatory cascade of the unstable plaque. Ascorbate depletion has been correlated with histaminemia which has been shown to impair endothelial-dependent vasodilation. This study evaluates ...

Myocardial edema occurs in many pathological conditions. We hypothesized that protein washdown at the myocardial microvascular exchange barrier would change the distribution of interstitial proteins from large to small molecules and diminish the effect of washdown on the colloid osmotic pressure (COP) of interstitial fluid and lymph. Dogs were instrumented ...
