Cardiovascular risk in cancer patients: initial experience from a cardio-oncology clinic in Mexico

Objective: To describe the cardiovascular risk from Mexican patients scheduled to initiate cancer treatment and to compare the risk between oncological and hematological malignancies.Methods: We enrolled patients referred for echocardiography before initiating cancer therapies.Left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) was evaluated.To estimate the risk for developing cancer therapy-related cardiovascular toxicity (CTR-CVT) we used the Heart Failure Association-International Cardio-Oncology Society risk score (HFA-ICOS).Results: 106 patients were studied, 83% (n = 88) had an oncological, and 17% (n = 18) a hematological malignancy.Breast cancer represented 89.8% (n = 79) of the oncological and lymphoma 61.1% (n = 11) of the hematological malignancies.Patients with oncological malignancies were older (55 11 vs. 46 14 years; p = 0.020) and more frequently female (95.5 vs. 44.4%;p < 0.001).Metastasis was more prevalent in patients with hematological malignancies (38.9 vs. 13.6%;p = 0.011).Mean LVEF was 59.42 6.36 and mean GLS was 20.26 4.89.Prevalence of borderline (50-54%) and reduced LVEF (< 50%) was 4.7 and 3.8%, respectively.Abnormal GLS (< 18%) was identified in 10.4%.HFA-ICOS classified 14.7% of oncological and 10.2% of hematological malignancies in the high and very high-risk categories for developing CTR-CVT (p = 0.68).Conclusions: A high risk for developing CTR-CVT was identified in 14.2% of our population.This risk was comparable among oncological and hematological malignancies.
