Abstract

Since its introduction 6 years ago, imatinib mesylate, a selective tyrosine kinase inhibitor, has been a phenomenon in treating chronic myelogenous leukemia (CML) with remarkably superior cytogenetic and molecular response rates at all stages of CML followed by longer progression free survival. Despite its extraordinarily high efficacy, adverse effects of imatinib mesylate such as edema, liver toxicity and fluid retention syndromes have been reported. Here we, for the first time, report development of heart failure in patients on imatinib mesylate medication and the possibility of brain natriuretic peptide (BNP) as a potential diagnostic (or predicting) marker for heart failure. Since plasma BNP levels in the two patients were exceptionally high, we then explored the possibility of genetic association of BNP with the development of heart failure to find no positive association.
