PURPOSE: Chronic myeloid leukemia (CML) is one of the common hematological malignancies in Nigeria. Cardiac abnormalities are associated with CML irrespective of treatment with tyrosine kinase inhibitors such as imatinib, which is available gratis in Nigeria.

OBJECTIVE: To assess the prevalence and patterns of cardiac dysfunction among patients with CML irrespective of treatment with imatinib using transthoracic echocardiography, and 12-lead surface electrocardiography.

PATIENTS AND METHODS: CML patients without Imatinib, CML patients with imatinib, and apparently healthy (age- and sex-matched) controls were 70 each in the study. Various echocardiographic parameters were measured and data obtained were analyzed, and the level of significance was taken as p < 0.05.

RESULTS: Of 70 CML patients with imatinib, 54.3% were men and 45.7% were women, while the CML group without imatinib had 62.9% men and 37.1% women, non-CML control had 54.3% men and 45.7% women. The average hematocrit was significantly lower in the CML group without Imatinib compared with the other groups (p

CONCLUSION: Cardiac abnormalities are present in CML patients with or without Imatinib treatment, with significant prevalence than what is seen in the non-CML control group.
