Early Diagnosis of Cardiovascular Diseases in Workers: Role of Standard and Advanced Echocardiography

Figure 2

Provocative testing in ischemic heart disease. (a) Exercise stress echocardiography in a patient with normal coronary arteries. Persistent normal wall motion after exercise (125 W). (b) Dobutamine stress echocardiography in a patient with ischemic heart disease. Anteroseptal hypokinesia at peak dose (40 mcg) is shown both by wall motion abnormalities (top panels) and strain analysis (bottom right panel, lighter segments in the “bull’s-eye” representation of peak systolic strain). LV = left ventricle.
