Prognostic value of myocardial infarct size and contractile reserve using magnetic resonance imaging.

Nov 2009 OBJECTIVES: Our aim was to assess the predictive value of myocardial infarct size assessed with late gadolinium-enhanced (LGE) magnetic resonance imaging (MRI) in medically treated patients with chronic myocardial infarction relative to contractile ... Read more...

Recommendation of low-salt diet and short-term outcomes in heart failure with preserved systolic function.

30 Oct 2009 BACKGROUND: Dietary sodium indiscretion frequently contributes to hospitalizations in elderly heart failure patients. Animal models suggest an important role for dietary sodium intake in the pathophysiology of heart failure with preserved systolic ... Read more...

Generation of functional ventricular heart muscle from mouse ventricular progenitor cells.

14 Oct 2009 The mammalian heart is formed from distinct sets of first and second heart field (FHF and SHF, respectively) progenitors. Although multipotent progenitors have previously been shown to give rise to cardiomyocytes, smooth muscle, and endothelial ... Read more...
