dc.description.abstractColor kinesis (CK) is a recently developed echocardiographic method based on acoustic quantification (AQ) that automatically tracks and displays endocardial motion in real time. We studied whether AQ and CK may provide quantitative assessment of global and regional right ventricular function in patients with acute anterior myocardial infarction since the evaluation of right ventricular function has important prognostic implications in these patients. Twenty consecutive patients with recent (within 1 week) acute anterior myocardial infarction and 15 age- and gender-matched controls were studied. Right ventricular AQ and CK images were acquired in the apical 4-chamber view. After image quality was optimized, AQ system for endocardial border detection was activated. Once the region of interest was drawn around the right ventricle, all gain compensations were adjusted to optimize tracking of the blood-endocardial interface. AQ waveforms of right ventricular fractional area change were displayed along with the electrocardiogram and concurrent cross sectional image. CK digitized right ventricular end-systolic images were evaluated by reviewing the stored loops obtained in all normal subjects and patients. To evaluate right ventricular systolic endocardial excursion, a further quantitative CK analysis was performed by measuring the systolic segmental endocardial motion and the time of systolic segmental endocardial motion. Compared to controls, acute anterior myocardial infarction patients had reduced right ventricular fractional area change (26 ± 7 vs 45 ± 6%, p < 0.05), reduced mean systolic segmental endocardial motion (14 ± 5 vs 21 ± 3 mm, p < 0.05), and reduced mean time of systolic segmental endocardial motion (210 ± 38 vs 290 ± 30 ms, p < 0.05). In conclusion, our data suggest that right ventricular systolic function is influenced in acute anterior myocardial infarction, and AQ and CK are feasible techniques for investigating right ventricular regional systolic function in these patients.en_US
