This study investigated whether the extent of perfusion defect determined by intravenous myocardial contrast echocardiography (MCE) in patients with acute infarction (AMI) treated primary percutaneous transluminal coronary angioplasty (PTCA) relates to flow reserve (CRF) for assessment reperfusion and is predictive left ventricular recovery.Twenty-five first AMI underwent MCE NC100100 intermittent harmonic imaging before PTCA after 24 hours. defined risk region at hours "no-reflow" region....

Aims We hypothesized that the assessment of left ventricular regional function (RF) and myocardial perfusion (MP) will provide incremental value over routine evaluation in patients who present to emergency department (ED) with chest pain (CP) no ST-segment elevation.

Tachycardia-induced cardiomyopathy refers to an impairment in left-ventricular function due chronic or prolonged tachycardia. We describe a heart transplant patient who developed cardiogenic shock tachycardia-induced cardiomyopathy. Low-output failure was further aggravated by administration of short-acting β-blocker during invasive hemodynamic monitoring. In contrast, rate control increasing doses ivabradine supported recovery from and led improvement the patient’s clinical condition as...

Background: Objective assessment of the cardiopulmonary capacity in patients with complex congenital cardiac disease often remains difficult clinical practice. The exercise test and determination levels brain natriuretic peptide plasma are established tests, but expensive. 6-minute walk is also validated, has not been used heart failure due to disease, nor compared other tests. We sought compare its value results testing measuring plasma. Methods: carried out a standardized 31 on same day...

OBJECTIVE: To evaluate the potential value of transoesophageal echocardiography combined with automated border detection and acoustic quantification for assessment elastic properties thoracic aorta in patients Marfan syndrome. SUBJECTS: 16 syndrome 12 age matched normal controls. METHODS: Transoesophageal was performed all subjects. Minimum maximum diameters descending were obtained from M mode images used on-line evaluation cross sectional aortic area peak positive changes over time....
