BACKGROUND Right ventricular (RV) function using myocardial velocities before and after a coronary artery bypass graft (CABG) is not known. METHODS Using pulsed wave Doppler tissue imaging, RV function was studied in 35 patients before and after CABG. Patients were followed-up for 1 year after the CABG. Myocardial velocities at the tricuspid annulus at(More)
The aim of this study was to determine whether exenatide improves haemodynamic function in patients with type 2 diabetes with congestive heart failure (CHF). The main eligibility criteria for inclusion were: male/female (18–80 years) with type 2 diabetes and CHF (ejection fraction ≤35%, and New York Heart Association functional class III or IV). Out of 237(More)
Serious adverse reactions to ropivacaine and lidocaine are rare. In this report, we describe a case of sudden cardiac arrest after an interscalene brachial plexus block with a mixture of 150 mg of ropivacaine and 360 mg of lidocaine in a previously healthy, 34-year-old, 97-kg man. Severe hypotension occurred after successful resuscitation, necessitating an(More)
BACKGROUND Inflammation is a major contributor to atherosclerotic vascular disease. Inflammatory parameters such as C-reactive protein (CRP) and Interleukin-6 (IL-6) have been shown to be strong predictors of cardiovascular events. The association between preoperative inflammatory parameters and early graft occlusion as well as cardiovascular events after(More)
Sinus bradycardia (SB) or atrioventricular junctional rhythm (AVJR) may produce circulatory insufficiency in anesthetized surgical patients, especially those with cardiovascular disease. Chronotropic drugs have been the preferred initial treatment, except when epicardial pacing is available. Alternative methods include transvenous or transcutaneous pacing.(More)
The effects of mental stress and dynamic exercise on central haemodynamic variables and cardiac sympathetic nerve activity were studied in 15 patients during both fixed rate ventricular-inhibited (VVI) and QT interval-sensing rate-responsive (TX) pacing. Haemodynamic measurements were made at rest, during a mental stress test and during supine exercise at(More)
BACKGROUND Decreased right ventricular (RV) function is a known echocardiographic finding after coronary artery bypass grafting (CABG). For patients with heart failure, RV dysfunction is a predictor of poor exercise capacity. The significance and time course of RV dysfunction and its relation to exercise capacity after CABG have not been elucidated,(More)
OBJECTIVE We prospectively tested the hypothesis that atrial enlargement and increased level of atrial natriuretic peptide, N-terminal atrial natriuretic peptide and brain natriuretic peptide would predict atrial fibrillation after coronary artery bypass grafting. METHODS Eighty-eight elective coronary artery bypass grafting patients had preoperative(More)
In patients with atrial fibrillation, the reduced right ventricular function determined by tricuspid annular motion before cardioversion returns to normal 1 month after successful cardioversion to sinus rhythm. The simplicity of recording the tricuspid annular motion provides an easy opportunity to assess right ventricular function following(More)
AIMS The aim of the study was to evaluate the changes in diastolic function after coronary artery bypass grafting (CABG), using pulsed-wave Doppler tissue imaging (DTI). METHODS Fifty-three patients with coronary artery disease were studied before and 3 and 12 months after CABG. Using pulsed-wave DTI, the mitral annular velocities were determined at 4(More)
