“…Using dobutamine stress echocardiography testing rather than exercise stress testing in pediatric patients with a history of KD [10], and in comparison with coronary angiography, the sensitivity was 19/21 or 90%, while the specificity was 100%. A recent review [11]suggested that exercise stress testing in adults with known or suspected coronary disease yielded sensitivities of 74–97%, with a pooled average of 85%. In the same article, the specificity varied from 64 to 100%, with a pooled average of 77%.…”

Patients with a history of Kawasaki’s disease (KD), particularly those not treated with intravenous γ-globulin, are at risk of coronary artery aneurysms and later obstruction. Twenty-eight patients with a history of KD (4 had coronary artery aneurysms) were examined with stress echocardiograms. Fourteen patients received γ-globulin ≤10 days of the onset, 8 patients received γ-globulin >10 days and 6 received no γ-globulin. The mean age at diagnosis was 7.2 ± 4.1 years; the median follow-up was 8.0 ± 7.4 years. All tests were negative. Using a binomial model, a power of 0.80, a sensitivity of each test of 80% and assuming uniform risk, the individual rate of failure to detect was <7%. At least 640 patients in each group would be needed to detect a difference of 3.5% vs. 7.0% and 184 in each group would be needed to detect a difference of 1.5% vs. 7.5%. We conclude that the probability of an abnormal stress echo in asymptomatic patients with a history of KD is at most 7% and that a more precise determination of the risk of an abnormal stress echo in KD requires a much larger study.

There were 133 cardiac events (54 cardiac deaths and 79 nonfatal MIs) during follow-up (median, three years). In a multiple-stepwise multivariate analysis model, clinical and exercise electrocardiography predictors of cardiac events were age, gender, hypertension, typical chest pain, previous MI, smoking, and resting ejection fraction. The percentage of ischemic segments at peak exercise provided additional information to the model (p = 0.0001). The presence of abnormalities in the left anterior descending (LAD) coronary artery distribution had an additional independent effect for the prediction of cardiac events (p = 0.001). Among patients with exercise echocardiographic abnormalities in a single vascular region, those with abnormalities in the left anterior descending coronary artery distribution had a higher event rate than patients with abnormalities elsewhere (3.2% vs. 2.1% at three years and 10.8% vs. 2.1% at five years; p = 0.009). CONCLUSIONS; Exercise WMAs in the distribution of the LAD coronary artery are associated with an increased risk of cardiac death and nonfatal MI. This risk is independent of the resting ejection fraction and the extent of WMAs during exercise.
