Late-onset Mitochondrial Cardiomyopathy Triggered by Anticancer Treatment
نویسندگان
چکیده
We report the case of a 62-year-old woman with a history of bilateral hearing impairment, who developed mitochondrial cardiomyopathy after chemotherapy. The patient underwent postoperative cisplatin chemotherapy after the surgical treatment of cervical cancer. The systolic function of her left ventricle decreased significantly. A tissue examination of the left ventricle revealed mitochondrial cardiomyopathy. Genetic testing revealed mutations in mitochondrial 3,243 A→G. Nine hundred fifty-five individual mutations were identified by next-generation sequencing. Since cardiovascular complications are the second leading cause of morbidity and mortality in patients undergoing cancer treatment, mitochondrial cardiomyopathy should be considered a potential cause of heart failure.

متن کاملOPA1 Mutation and Late-Onset Cardiomyopathy: Mitochondrial Dysfunction and mtDNA Instability
BACKGROUND Mitochondrial fusion protein mutations are a cause of inherited neuropathies such as Charcot-Marie-Tooth disease and dominant optic atrophy. Previously we reported that the fusion protein optic atrophy 1 (OPA1) is decreased in heart failure. METHODS AND RESULTS We investigated cardiac function, mitochondrial function, and mtDNA stability in a mouse model of the disease with OPA1 mu...
متن کاملEvaluation of Cardiac Mitochondrial Function by a Nuclear Imaging Technique using Technetium-99m-MIBI Uptake Kinetics
Mitochondria play an important role in energy production for the cell. The proper function of a myocardial cell largely depends on the functional capacity of the mitochondria. Therefore it is necessary to establish a novel and reliable method for a non-invasive assessment of mitochondrial function and metabolism in humans. Although originally designed for evaluating myocardial perfusion, 99mTc...
