N2 - Asymptomatic diastolic dysfunction (DD) with preserved left ventricular ejection fraction (LVEF) is suspected to precede late cardiac events in cancer survivors treated by chemotherapy. We conducted the first multicenter study of early DD induced by chemotherapy. Patients who were candidates for standard dose chemotherapy were screened for the absence of cardiovascular risk factors, LVEF ≥50%, normal-for-age diastolic function at echocardiography (E/A ratio, E wave deceleration time; DT), normal levels of potential DD biomarkers like Nt-proBNP (≤125 pg/mL), and cardiac troponin I (cTnI, ≤0.05 ng/mL). Mitral Doppler (E/E’) was left at the investigator’s discretion. Chemotherapy-induced DD with preserved LVEF was diagnosed for patients showing LVEF ≥50% and any of the following: Nt-proBNP > 125 pg/mL, cTnI > 0.05 ng/mL, and out-of-range E/A and DT. Eighty patients (68 males, 12 females, median age 49 years) were evaluated at 1 week after chemotherapy (T1). Thirty-three protocol-defined diastolic events were observed (15 Nt-proBNP > 125 pg/mL, 14 grade I DD by E/A and DT, 4 cTnI > 0.05 ng/mL). The events occurred in 29 asymptomatic patients with LVEF ≥50% (36% incidence of DD with preserved LVEF). Interactions occurred between biomarkers and grade I DD. E/E’ abnormalities were not observed. Both anthracycline-based and nonanthracycline regimens induced DD. These findings show that biomarkers and echocardiography intercept early DD in otherwise asymptomatic low-risk cancer patients treated by standard dose chemotherapy. These findings therefore call for the adequate cardiac management of cancer patients.
