Regional ventricular dynamics during acute coronary occlusion: A comparison of invasive with non-invasive echocardiographic markers to detect and quantify myocardial ischaemia-observations made during off-pump coronary surgery
چکیده انگلیسی
We compared non-invasive markers commonly used in stress echocardiography using measurements of the fall in regional myocardial work with coronary occlusion as a standard. 27 patients were studied using transoesophageal echocardiography and simultaneous high fidelity left ventricular pressure during off-pump coronary surgery. Delayed myocardial thickening had the highest qualitative concordance with the gold standard of a fall in effective work, while regression models identified three significant predictors; the interval Q wave to the onset of regional thickening, duration of post-ejection thickening and peak thickening rate. These markers may complement current non-invasive indices of ischaemia during clinical stress testing.
