OBJECTIVES Retrospective analysis of five cases of coronary vein balloon angioplasty performed to allow insertion of left ventricular pacing leads. BACKGROUND Coronary vein stenoses or an insufficient vessel caliber can preclude transvenous placement of coronary vein leads. METHODS We compared our total patient population (n = 218), in whom we implanted coronary vein leads, to those five pa...

BACKGROUND Experimental evidence indicates that magnesium sulfate may have potential cardioprotective properties as an adjunct to coronary reperfusion. The present study was designed to examine the hypothesis that magnesium might have beneficial effects on left ventricular (LV) function and coronary microvascular function in patients with acute myocardial infarction (AMI). METHODS AND RESULTS...

Background: There are few studies about the impact of diagonal branch blood flow on echocardiographic findings in patients with first acute anterior myocardial infarction undergoing primary angioplasty. Objectives: We aimed to compare left ventricular systolic function measures ST-segment elevation (STEMI) treated angioplasty based after procedure. Methods: This study was a single-center that e...

Cardiac rehabilitation programs are safe and effective in improving the functional activities of patients with cardiac disease, but they may be hazardous to those patients whose life might be in jeopardy if subjected to exercise. It is clear that not all cardiac patients require supervised rehabilitation programs to return to normal pre-cardiac-event activities. Many patients who have suffered ...

Objective: Evaluate whether early routine post-fibrinolysis angioplasty represents a reasonable reperfusion option for victims of ST-elevation myocardial infarction (STEMI), so that these patients could benefit more. Methods: A total of 936 STEMI patients were enrolled in this study to full Urokinase within 3 hours (h) followed by stenting within 3 12 h (Ultra early routine post-fibrinolysis an...

BACKGROUND The relation between remodeling and left ventricular (LV) diastolic function has not yet been fully investigated. The aim of this study was to determine whether early assessment of Doppler-derived mitral deceleration time (DT), a measure of LV compliance and filling, may predict progressive LV dilation after acute myocardial infarction (AMI). METHODS AND RESULTS Fifty-one patients ...

Objectives. This study evaluated the relation between reversible segmental left ventricular dysfunction and frequency domain measures of heart period variability in patients with coronary artery disease, Background. Heart period variability is frequently reduced in patients with coronary artery disease. However, the merhavisms of this reduction are still unclear . NMethods. Echocardiographic le...

BACKGROUND We hypothesized that preserved microvascular integrity in the area at risk would favorably influence left ventricular (LV) remodeling and long-term outcome after acute myocardial infarction. METHODS AND RESULTS Before and after successful primary angioplasty (percutaneous transluminal coronary angioplasty [PTCA]), 124 patients with acute myocardial infarction underwent intracoronar...

conclusions diagnosis of tachycardia-induced cardiomyopathy in children is important, since appropriate treatment improves the prognosis. every child with recurrent and persistent palpitation with the first episode of congestive heart failure should be evaluated for tachycardia- induced cardiomyopathy. introduction tachycardia-induced cardiomyopathy (tic) is a ventricular dysfunction secondary ...
