Mitral valve in ischemic versus idiopathic dilated cardiomyopathy

Outcome after mitral valve surgery for functional mitral regurgitation in idiopathic dilated cardiomyopathy

Methods We retrospectively investigated 146 patients (131 men, 16 women; mean age, 67 years) with severe functional mitral valve (MV) insufficiency due to dilated cardiomyopathy that were operated on between 2004 till 2012. 35 pts were in New York Heart Association class IV and 102 were in class III. Most of pts had severe enlarged LV (mean end-diastolic size 73.7±7,1ml and volume 293 ±80ml) wi...

The value of myocardial perfusion imaging in differentiating between idiopathic dilated cardiomyopathy from the ischemic form [Persian]

Introduction: Differentiating between ischemic cardiomyopathy (ICM) and idiopathic dilated cardiomyopathy (IDCM) is important as coronary revascularization can improve prognosis in the ischemic subgroup. Due to inherent problems of coronary angiography in patients with depressed ejection fraction (EF) introducing a noninvasive tool to diagnose those who will benefit from angiography seems...

Differences in beta-adrenergic neuroeffector mechanisms in ischemic versus idiopathic dilated cardiomyopathy.

BACKGROUND We measured the content and activities of components of the beta-adrenergic receptor-G protein-adenylate cyclase complex and adrenergic neurotransmitter levels in left and right ventricular myocardial preparations derived from 77 end-stage failing human hearts from patients with idiopathic dilated cardiomyopathy (IDC) or ischemic dilated cardiomyopathy (ISCDC). METHODS AND RESULTS ...

Beta-blockade with bucindolol in heart failure caused by ischemic versus idiopathic dilated cardiomyopathy.

BACKGROUND We investigated the effects of bucindolol, a nonselective, non-ISA beta-blocker with mild-vasodilatory properties, in patients with congestive heart failure from ischemic dilated cardiomyopathy (ISCDC, n = 27) and compared the results with those in subjects with heart failure from idiopathic dilated cardiomyopathy (IDC, n = 22). METHODS AND RESULTS Patients were randomized in a dou...
