Bevacizumab: A Rare Cause of Nonischemic Cardiomyopathy.

ABSTRACT: Left ventricular dysfunction is a rare side effect of bevacizumab occurring in 2-4% of cases. We report the case of a 68-year-old woman who presented to the emergency department (ED) with sudden onset of shortness of breath, orthopnea, and paroxysmal nocturnal dyspnea. She was tachypneic and in respiratory distress. Physical examination revealed jugular venous distention, diffuse expiratory wheeze, and bipedal edema. She had been started on bevacizumab for the treatment of hereditary hemorrhagic telangiectasia 1 month prior to presentation. Laboratory tests revealed BNP of 1697?pg/ml with slightly elevated troponin 0.05?ng/ml. Chest X-ray showed interstitial edema with cardiomegaly, and transthoracic echocardiogram showed ejection fraction of 30% with global hypokinesia. Left heart catheterization revealed widely patent coronary arteries. Flash pulmonary edema secondary to acute left ventricular dysfunction in this case was attributed to recent treatment with bevacizumab after ruling out other possible etiologies. This case highlights the importance of early recognition of this rare but potentially reversible side effect of bevacizumab to prevent long-term sequelae.

Project description:BACKGROUND:Ischemic cardiomyopathy (ICM) and dilated cardiomyopathy (DCM) differ in histopathology and prognosis. Although transendocardial delivery of mesenchymal stem cells is safe and provides cardiovascular benefits in both, a comparison of mesenchymal stem cell efficacy in ICM versus DCM has not been done. METHODS AND RESULTS:We conducted a subanalysis of 3 single-center, randomized, and blinded clinical trials: (1) TAC-HFT (Transendocardial Autologous Mesenchymal Stem Cells and Mononuclear Bone Marrow Cells in Ischemic Heart Failure Trial); (2) POSEIDON (A Phase I/II, Randomized Pilot Study of the Comparative Safety and Efficacy of Transendocardial Injection of Autologous Mesenchymal Stem Cells Versus Allogeneic Mesenchymal Stem Cells in Patients With Chronic Ischemic Left Ventricular Dysfunction Secondary to Myocardial Infarction); and (3) POSEIDON-DCM (Percutaneous Stem Cell Injection Delivery Effects on Neomyogenesis in Dilated Cardiomyopathy). Baseline and 1-year cardiac structure and function and quality-of-life data were compared in a post hoc pooled analysis including ICM (n=46) and DCM (n=33) patients who received autologous or allogeneic mesenchymal stem cells. Ejection fraction improved in DCM by 7% (within-group, P=0.002) compared to ICM (1.5%; within-group, P=0.14; between-group, P=0.003). Similarly, stroke volume increased in DCM by 10.59 mL (P=0.046) versus ICM (-0.2 mL; P=0.73; between-group, P=0.02). End-diastolic volume improved only in ICM (10.6 mL; P=0.04) and end-systolic volume improved only in DCM (17.8 mL; P=0.049). The sphericity index decreased only in ICM (-0.04; P=0.0002). End-diastolic mass increased in ICM (23.1 g; P<0.0001) versus DCM (-4.1 g; P=0.34; between-group, P=0.007). The 6-minute walk test improved in DCM (31.1 m; P=0.009) and ICM (36.3 m; P=0.006) with no between-group difference (P=0.79). The New York Heart Association class improved in DCM (P=0.005) and ICM (P=0.02; between-group P=0.20). The Minnesota Living with Heart Failure Questionnaire improved in DCM (-19.5; P=0.002) and ICM (-6.4; P=0.03; ? between-group difference P=0.042) patients. CONCLUSIONS:Mesenchymal stem cell therapy is beneficial in DCM and ICM patients, despite variable effects on cardiac phenotypic outcomes. Whereas cardiac function improved preferentially in DCM patients, ICM patients experienced reverse remodeling. Mesenchymal stem cell therapy enhanced quality of life and functional capacity in both etiologies. CLINICAL TRIAL REGISTRATION:URL: http://www.clinicaltrials.gov.
