摘要: Abstract Objective: Changes in left ventricular geometry and shape are prominent characteristics of cardiomyopathy. The aim this study was to investigate changes after inotropic stimulation patients with chronic nonischemic dilated Methods: A low infusion rate echocardiography-dobutamine performed 35 consecutive (age: 50 ± 8 years) known Peak exercise oxygen consumption measured the day before. Overall chamber assessed by using long-/minor-axis dimension ratio obtained at end-diastole end-systole. Results: After dobutamine infusion, entire group an increase systolic (0.11 0.13 mm, P Conclusion: response sphericity index might be alternative functional status failing heart (J Am Soc Echocardiogr 2003;16:132-9.)
