Effects of anti-vasospastic agents in Japanese patients with dilated cardiomyopathy and coronary vasospasm.

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...

Severe multivessel coronary vasospasm and left ventricular ballooning syndrome.

In their first description of Takotsubo cardiomyopathy (TC), Dote et al1 hypothesized that the disease was caused by multivessel coronary vasospasm, because 4 of 5 patients in their report had either spontaneous or provocable coronary vasospasm on coronary angiography. However, later studies did not find supporting evidence for the pathogenic role of coronary vasospasm. Recently, the vasospasm ...

Direct myocardial and coronary effects of enalaprilat in patients with dilated cardiomyopathy: assessment by a bilateral intracoronary infusion technique.

Angiotensin II elicits contractile responses in the coronary arteries and myocardial tissue, which suggests that blockade of the renin-angiotensin system by specific agents should lead to both coronary vasodilation and an alteration of left ventricular inotropism. The present work was designed to delineate--independently from its systemic effects--the intrinsic actions of an angiotensin convert...
