Doxorubicinol (dxol) is the major metabolite formed in the hearts of cancer patients being treated with the widely used chemotherapeutic agent, doxorubicin (dox). The well-documented cardiomyopathy associated with dox treatment has been studied in vitro and ex vivo providing evidence that the C-13 hydroxy metabolite, dxol, might play a key role in the development of dox-induced cardiotoxicity. ...

Fluorouracil (5-FU) is an antimetabolite that has become the cornerstone chemotherapeutic agent used to treat tumors of the gastrointestinal tract. Although proven to be effective, 5-FU can cause cardiotoxicity, which can be life-threatening. Adverse cardiac-related events induced by 5-FU include angina pectoris, myocardial infarction, supraventricular tachycardia, and atrial fibrillation. Nurs...

Of 38 patients referred with suspected cardiotoxicity after administration of antineoplastic drugs, 11 patients with signs of manifest or latent anthracycline cardiotoxicity were selected for heart catheterisation with endomyocardial biopsy. Ultrastructural abnormalities of the myocytes with myofibrillar loss and cytoplasmic vacuolation were present in most patients and these findings were more...

This study examined the value of blood marker S100A1 in detecting cardiotoxicity induced by chemotherapy agents; trastuzumab and lapatinib, in normal rat heart. The rats were divided into three groups: control (n = 8, no treatment), T (n = 8, one time ip treatment with 10 mg/kg trastuzumab) and L (n = 8, oral treatment with 100 mg/kg/day lapatinib for 7 days). The activities of oxidative stress...

The chronic cardiotoxicity of the cytotoxic agents such as anthracyclines is one of the main factors, which limits their prolonged use. Clinically, this cardiotoxicity results in a cardiomyopathy with irreversible congestive heart failure, with high mortality. The molecular mechanisms, which could explain this cardiac toxicity, are complex but it seems distinct from the anticancer mechanism. Se...

Doxorubicin (DOX) is a potent and currently available antitumor therapeutic agent; however, its clinical application is limited by the occurrence of cardiotoxicity. Preliminary evidence indicates that hydrogen sulfide (H2S) may exert protective effects against DOX cardiotoxicity. Therefore, the aim of the present study was to investigate whether calreticulin (CRT) is involved in the cardioprote...

background: nt-probnp is a marker that is released from ventricles in response to pressure and volume overload. raised plasma level of nt-probnp is seen in ventricular dysfunction, ventricular muscular mass reduction or ventricular ischemia. anthracyclines are widely used in treatment of pediatric cancer but their use is associated with cardiotoxicity which increases mortality and morbidity. we...

The cardiac toxicity has been recognized as a major medical problem that negatively affecting quality of life and prognosis in cancer survivors within chemotherapies and after ending of the treatment. The mini review is focused on the innate mechanisms of cardiotoxicity and the techniques regarding the cardiac evaluation of cancer patients. It has discussed radial and circumferential strain rat...

This report presents a case of tacrolimus cardiotoxicity in an adult patient who received tacrolimus immunosuppression for orthotopic liver transplant (OLT). Tacrolimus-associated cardiotoxicity has been described in the literature, however this is the first case to document the development of a dilated cardiomyopathy in a patient shortly after initiating tacrolimus therapy post transplant. Wit...

The growing number of aged patients with cancer and protracted periods treatment chemotherapic drugs radiotheraphy have made the administration cardiovascular side effects treatment-related cardiotoxicity an important issue. For these reason, Cardio-oncology has received increasing attention. cases cardiotoxicity, especially atherosclerotic lesions increased, making involvement onco-cardiologis...
