The clinical value of echocardiography and acoustic cardiography to monitor patients undergoing anthracycline chemotherapy.

Abstract：

BACKGROUND:Investigate the usefulness of echocardiography and acoustic cardiography to monitor patients exposed to anthracycline chemotherapy. HYPOTHESIS:Serial echocardiographies to monitor systolic function may not be neccessary in all patients undergoing anthracycline chemotherapy. METHODS:In a prospective study, consecutive patients undergoing anthracycline-containing chemotherapy were evaluated with echocardiography and acoustic cardiography at baseline, after completion of chemotherapy, and after a median follow-up of 3.8 years. Systolic dysfunction was defined as a left ventricular ejection fraction≤50%. RESULTS:A total of 187 patients (83% female) with a mean age of 55±14 years underwent chemotherapy for breast cancer (73%), malignant lymphoma (23%), and sarcoma (4%). None of the patients had systolic dysfunction at baseline. Patients were treated with doxorubicin 276±74 mg/m2 or epirubicin 317±55 mg/m2. After chemotherapy, 170 (91%) had normal systolic function, 8 (4%) developed systolic dysfunction, and 9 (5%) had died. Of those 8 patients with systolic dysfunction, 4 (50%) improved to normal systolic function, 1 (13%) remained unchanged, and 3 (37%) died. Patients with normal systolic function after chemotherapy had a mortality rate of 3.5%, and 1.8% developed late systolic dysfunction. Acoustic cardiography-derived percent electromechanical activation time>12.4% had a sensitivity of 88% and a specificity of 84% to identify patients with systolic dysfunction (area under the receiver operating characteristic curve 0.87). CONCLUSIONS:Patients with systolic dysfunction early after anthracycline treatment had worse outcome. Acoustic cardiography was able to identify these patients with a high sensitivity and specificity. Based on the findings of this study, we propose a simple algorithm to monitor patients undergoing anthracycline-containing chemotherapy.
