Background: Conventional isometric stress echocardiography is not routinely used in the assessment of coronary artery disease (CAD)
because of low sensitivity in diagnosis of coronary lesions. The purpose of this study was to determine diagnostic value of new modification
of isometric handgrip stress echocardiography for detection of CAD – maximal isometric handgrip/emotional stress echocardiography
(MISE) in patients with suspected CAD compared with conventional dobutamine stress echocardiography (DSE).
Methods: 197 patients with suspected CAD were studied before coronary angiography: 87 of them underwent MISE, 110 – conventional
DSE. After baseline measurements by echocardiography at rest, MISE patients undertook a handgrip-maneuver with the balloons. The
echocardiographic image was monitored throughout the maneuver. The squeezing of the balloons was performed with the both hands and
sustained at maximal voluntary contraction for 3 min. The emotional component of stress was performed: the investigator inspired patient
to maximal effort during the stress. DSE was performed using standard protocol. Quantitative coronary angiography served as a reference
standard for anatomic disease (significant CAD defined as ≥50% reference diameter).
Results: CAD patients revealed by MISE and DSE did not differ in rate of multiple coronary stenoses: 40.4% and 45.5% (p=NS). MISE
gave virtually equal sensitivity, 84.5% (95% CL=74.1-94.8) compared to DSE, 87.3% (95% CI=78.3-96.3) in obtained data (p=NS) and
specificity – 85.7% (95% CI=71.4-99.7) and 76.6% (95% CI=62.5-90.7), respectively (p=NS). The positive predictive value of two tests was
almost similar, 92.5% (95% CI=84.9-99.8) for MISE and 83.3% (95% CI=73.3-93.4) for DSE, as well as the negative predictive value: for
MISE 72.7% (95% CI=54.5-90.9) and 81.8% (95% CI=69.0-94.7) for DSE (both p=NS). Overall accuracy for MISE did not differ from DSE –
84.9% (95% CI=76.5-93.3) and 82.7% (95% CI=74.8-90.7), p=NS.
Conclusions: MISE and DSE have a similar diagnostic value in detection of significant coronary lesions in suspected CAD patients.
However, MISE is easier to carry out, this method is less time consuming and less expensive compared to DSE.
