Background:
Despite the inference about the cardiotoxicity induced by Carfilzomib, no validated risk prediction models for adverse cardiovascular events in a real-life population are available.
Objectives:
The aim of this study was to evaluate the performance of the risk stratification score for Carfilzomib-induced cardiotoxicity of the Heart Failure Association of the European Society of Cardiology and the International Cardio-Oncology Society (HFA-ICOS) in patients with multiple myeloma (MM).
Methods:
This is a prospective, real-world study including MM patients consecutively enrolled prior to starting Carfilzomib, divided into levels of risk according to the HFA-ICOS proforma.
Results:
Of 169 patients, 11.8% were classified as 'low risk', 38.5% as 'medium risk', 45.6% as 'high risk' and 4.1% as 'very high risk' at baseline. A total of 89 (52.7%) patients experienced one of the following events: 36 (21.3%) had at least one cardiovascular event and 77 (45.6%) had almost one hypertension-related event. No significant differences were observed for the incidence of any cardiovascular events between the different levels of risk (p > 0.05), even considering the HFA-ICOS score as a continuous variable. The integration of the score with the baseline systolic blood pressure and pulse wave velocity enhanced the accuracy of the score (AUC 0.557 vs. 0.736).
Conclusions:
The HFA-ICOS score did not discriminate between patients at low, medium and high risk, showing a limited discriminatory power in predicting the risk of events in our population. The integration of other parameters in the HFA-ICOS score, such as systolic blood pressure and pulse wave velocity, improved the performance of the score.
