BACKGROUND: Chemotherapy-induced cardiomyopathy (CICM) and heart failure are major complications of cancer therapeutics and can result in significant morbidity and mortality. There is limited data on the incidence and risk factors of CICM in African American and Afro-Caribbean patients. METHODS: We performed a retrospective chart review to evaluate the baseline characteristics that may predispose to CICM. Patients were African American and Afro-Caribbean ethnicity. Data was collected between 2014 to 2018. Patients had transthoracic echocardiogram (TTE) or multigated acquisition scan (MUGA) prior to cancer therapy and every 3 months thereafter, until the end of the regimen. CICM was defined as a ≥16% reduction in LVEF or ≥10% reduction in LVEF to a value <50%. RESULTS: A total of 230 patients were studied, with a mean age of 54±12 years with 91% were females, BMI 30±4, 81% were taking anthracyclines, 87% were on Trastuzumab while 5% were receiving both medications. The prevalence of comorbidities was as follows: hypertension 8%, diabetes mellitus 8%, ESRD 8%, dyslipidemia 8%, CAD 7%. The incidence of CICM was 7% overall, while it was 6% and 8% for patients taking Anthracyclines and Trastuzumab, respectively. CICM was associated with dyslipidemia (r= .22, p= .001), hypertension (r= .12, p= .05), baseline ejection fraction (r= -.21, p= .001) and concomitant use of radiation therapy (r= .147, p= .02), but not with age, gender, beta blocker use, angiotensin converting enzyme inhibitor use, number of chemotherapy cycles or stage of the malignancy. On multivariate analysis CICM was independently associated with baseline ejection fraction (β= -.193, P= .003) and dyslipidemia (β= -.20, P= .003). CONCLUSION: The incidence of CICM in African Americans and Afro-Caribbean is higher than reported in the general population. Dyslipidemia and baseline ejection fraction were seen as the major risk factors associated with the higher incidence of CICM.
