A randomized comparison of off-pump and on-pump multivessel coronary-artery bypass surgery.
BACKGROUND The effect of the use of coronary-artery bypass surgery without cardiopulmonary bypass and cardiac arrest ("off pump") on graft patency remains uncertain. We undertook a prospective,Expand

Comparison of segmental and global markers of dyssynchrony in predicting clinical response to cardiac resynchronization.
AIMS Cardiac resynchronization therapy (CRT) reduces inter- and intraventricular dyssynchrony and shortens total isovolumic time (t-IVT). We compared the extent to which the values of ventricularExpand

Femoral haemostasis after transcatheter therapeutic intervention: a prospective randomised study of the angio-seal device vs. the femostop device.
BACKGROUND A number of haemostatic devices are available to facilitate early haemostasis following transfemoral interventional procedures. METHODS AND RESULTS We have prospectively compared 150Expand

Inhaled platelet-activating factor causes pulmonary neutrophil sequestration in normal humans.
Inhaled platelet-activating factor (PAF) causes bronchoconstriction and transient peripheral neutropenia in humans. We studied eight normal subjects to investigate whether inhaled PAF causedExpand

Cardiogenic shock secondary to mitral stenosis treated by balloon mitral valvuloplasty.
Percutaneous balloon mitral valvuloplasty is a well-established elective treatment for mitral stenosis in selected patients; it has been used to treat cardiogenic shock secondary to aortic stenosisExpand

Comparison of three different methods used to achieve local anesthesia for fiberoptic bronchoscopy.
A patient's tolerance of fiberoptic bronchoscopy depends on the effectiveness of local anesthesia. This study compares the three different methods of local anesthesia in common use After sedation,Expand

Diagnostic techniques in suspected thoracic aortic dissection.
Transthoracic echocardiography After presenting at a district general hospital the patient with a suspected dissection should undergo transthoracic echocardiography. Most district hospitals now haveExpand

Systemic platelet effects of contrast media: implications for cardiologic research and clinical practice.
BACKGROUND Angiographic contrast media cause platelet activation and decrease aggregability in vitro. We have previously shown in vitro a significant antiplatelet effect of contrast media at theExpand

Non-elective intra-coronary stenting: are the clinical outcomes comparable to elective stenting at 6 months?
The aim of this study was to compare prospectively the clinical outcome of patients treated with intra-coronary stents as a non-elective/bailout procedure for acute or threatened vessel closure, withExpand

Restrictive cardiomyopathy and constrictive pericarditis: non-invasive distinction by digitised M mode echocardiography.
It is difficult to distinguish between restrictive cardiomyopathy and constrictive pericarditis on the basis of clinical findings and simple investigation. Cardiac catheterisation has been theExpand
