Despite doxorubicin (Dox) being one of the most widely used chemotherapy agents for breast, blood and lung cancers, its use in colon cancer is limited due to increased drug resistance and severe cardiotoxic side effects that increase mortality associated with its use at high doses. Therefore, better adjuvant therapies are warranted to improve the chemotherapeutic efficacy and to decrease cardiotoxicity. We have recently shown that aldose reductase inhibitor, fidarestat, increases the Dox-induced colon cancer cell death and reduces cardiomyopathy...

Cardio-oncology is a rapidly growing field aimed at improving the quality of care of cancer patients by preventing and monitoring cardiovascular complications resulting from cancer treatment. Cardiac imaging, and in particular, transthoracic echocardiography, plays an essential role in the baseline assessment and serial follow-up of cardio-oncology patients. Areas covered: This review article discusses the role of cardiac imaging with a focus on advanced echocardiography for the detection and management of cancer therapy related cardiovascular complications, in particular, left ventricular dysfunction and heart failure...

We present the case of a 51-year-old woman admitted to our intensive care unit following an intentional overdose of a calcium channel antagonist and a beta blocker. The resultant hypotension was reversed with glucagon, noradrenaline, calcium and high-dose insulin. Despite these interventions, she remained vasoplegic and received a delayed, standard dose of intralipid. Subsequently, the vasoplegia resolved rapidly, and the vasopressor was stopped. Here, we review the management of overdose of calcium channel and beta-adrenergic receptor blockers, concentrating on the pharmacology of lipid emulsion therapy...

The prediction of cancer therapeutics-related cardiac dysfunction (CTRCD) is an essential aspect of care for individuals who receive potentially cardiotoxic oncologic treatments. Certain clinical risk factors have been described for incident CTRCD, and measurement of left ventricular (LV) longitudinal strain by speckle tracking 2-dimensional echocardiography (2DE) is the best-validated myocardial mechanical imaging assessment to detect subtle changes in LV function during cancer treatment. However, the direct integration of clinical and imaging risk factors to predict CTRCD has not yet been extensively examined...

How fish respond to hypoxia, a common stressor, can be altered by simultaneous exposure to pollutants like bisphenol A (BPA), a plasticizer. BPA is cardiotoxic and interferes with the hypoxia inducible factor pathway (HIF-1α), therefore disrupting the hypoxic response. Co-exposure to hypoxia and BPA also causes severe bradycardia and reduced cardiac output in zebrafish larvae. The purpose of this work was to determine how the cardiovascular effects of co-exposure vary with BPA concentration and persist beyond exposure...

Candidate patients for cardiac surgery procedures with a history of malignancies and antitumour therapy or with an active cancer and on antineoplastic treatment are increasingly common in daily practice. Oncological therapy can lead to cardiovascular injury and, therefore, has the potential for impacting operative risks and surgical strategies. This means that a number of considerations are essential to take into account prior to cardiac surgery. These include the type of cancer, previous cardiotoxicity or concomitant antitumour therapy, reversibility or irreversibility of such complications, the interaction between cancer disease course and extracorporeal circulation, the need for associated surgery and the impact of cancer on early and long-term outcomes...

Tyrosine kinase inhibitors (TKIs) are targeted therapies rapidly becoming favored over conventional cytotoxic chemotherapeutics. Our study investigates two FDA approved TKIs, DASATINIB; indicated for IMATINIB-refractory chronic myeloid leukemia, and SORAFENIB; indicated for hepatocellular carcinoma and advanced renal cell carcinoma. Limited but crucial evidence suggests that these agents can have cardiotoxic side effects ranging from hypertension to heart failure. A greater understanding of the underlying mechanisms of this cardiotoxicity are needed as concerns grow and the capacity to anticipate them is lacking...

The voltage-gated KCNQ1 potassium ion channel interacts with the type I transmembrane protein minK (KCNE1) to generate the slow delayed rectifier (IKs) current in the heart. Mutations in these transmembrane proteins have been linked with several heart-related issues, including long QT syndromes (LQTS), congenital atrial fibrillation, and short QT syndrome. Off-target interactions of several drugs with that of KCNQ1/KCNE1 ion channel complex have been known to cause fatal cardiac irregularities. Thus, KCNQ1/KCNE1 remains an important avenue for drug-design and discovery research...

Introduction: The toxic side effects of doxorubicin (DOX) have limited its use in chemotherapy. Neither liposomal DOX nor pegylated liposomal DOX are able to completely resolve this issue. This is a proof-of-concept study testing aptamer-drug conjugate (ApDC) targeted delivery systems for chemotherapeutic drugs. Methods: Aptamer library targeting human epidermal growth factor receptor 3 (HER3) was screened and affinity was determined by enzyme-linked immunosorbent assay...

BACKGROUND: Loperamide has been increasing in popularity recently for its effects separate from treatment of diarrhea. In large doses or in combination with other agents, it can lead to desirable effects in the central nervous system. However, cardiotoxicity has been reported with its abuse. CASE REPORT: A 49-year-old male who had been chronically abusing loperamide was found to have Brugada-like changes on his electrocardiogram (ECG). He had no other clinical symptoms associated with Brugada syndrome and did not have similar findings on previous ECGs...

Although Danhong injection (DHI) has been clearly shown to attenuate ischemic myocardial injury and improve heart function, there is no research regarding its role in doxorubicin (DOX)-induced cardiomyopathy. In this study, we aimed to investigate the reverse effect of DHI on DOX-induced cardiotoxicity in H9c2 cells. The results of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay demonstrated that DHI had no cytotoxicity towards the relevant cell line unless the concentration was as high as 50 μL/mL...

Anagrelide is a phosphodiesterase-3 inhibitor used in the treatment of essential thrombocythaemia. Cardiovascular side effects such as ventricular tachycardia and cardiomyopathy are rare but potentially fatal and should be made known to patients before starting the medication. It usually arises within the first 6 months after initiation of therapy and may be dose related. The elderly population are particularly susceptible. These cardiotoxicities result from an increase in cyclic AMP that induces positive inotropic and chronotropic effects and are often reversible with cessation of use...

Cardiovascular disease (CVD) remains the leading cause of mortality in women, yet many people perceive breast cancer to be the number one threat to women's health. CVD and breast cancer have several overlapping risk factors, such as obesity and smoking. Additionally, current breast cancer treatments can have a negative impact on cardiovascular health (eg, left ventricular dysfunction, accelerated CVD), and for women with pre-existing CVD, this might influence cancer treatment decisions by both the patient and the provider...

<u>Rationale:</u> Dipeptidyl peptidase-4 (DPP-4) inhibitors have increased the risk of heart failure events in both randomized clinical trials and observational studies, but the mechanisms that underlie their deleterious effect remain to be elucidated. Previous work has implicated a role of these drugs to promote cardiac fibrosis. <u>Objective:</u> This paper postulates that DPP-4 inhibitors increase the risk of heart failure events by activating the sympathetic nervous system to stimulate cardiomyocyte cell death, and it crystallizes the findings from both experimental studies and clinical trials that support the hypothesis...

Oxidative stress and apoptosis serve an essential role in cisplatin-induced cardiotoxicity, which limits its clinical use, and increases the risk of cardiovascular disease. As a natural drug, the antioxidant and antitumor effects of cyanidin have been recognized, but its protective effect on cisplatin-induced cardiomyocyte cytotoxicity remains unclear. H9c2 cells were treated with cisplatin (1-40 µM) in the presence or absence of cyanidin (40-80 µM), subsequently; oxidative stress, apoptosis and mitochondrial function were assessed using several techniques...

Over the past few decades, the number of long term survivors of childhood cancers has been increased exponentially. However, among these survivors, treatment-related toxicity, especially cardiotoxicity, is becoming the essential cause of morbidity and mortality. Thus, preventing the treatment-related adverse effects is important to increase the event free survival during the treatment of cancer in children and adolescents. Accumulating evidence has demonstrated that hydrogen sulfide (H2S) exerts a protective role on cardiomyocytes through a variety of mechanisms...

Cardiotoxicity is a dose-limiting and potentially lethal complication of anthracycline administration. Previous studies failed to determine definitive toxic doses or cardioprotective factors. Current dosing strategies may utilize unnecessarily high anthracycline doses, such that survival benefit may not outweigh increased toxicity rates. A systematic review of randomized controlled trials and prospective/retrospective studies investigating anthracycline treatment in pediatric solid tumors was performed from PubMed/MEDLINE and Cochrane databases...

Current screening guidelines are available for anthracycline-induced cardiotoxicity. However, the utility of echocardiogram screening for late-onset anthracycline cardiotoxicity especially in the decade immediately after end of therapy is debatable. A retrospective chart review of patients seen in the Thriving after Cancer Clinic at Rady Children's Hospital January 2006 to December 2013 was performed. Treatment data, echocardiogram results, cardiology referral notes and cardiac medication data were abstracted from anthracycline-exposed survivors...
