Echocardiography and cancer therapeutics-related cardiac dysfunction

This article reviews the utility of GLS for early detection of cardiotoxicity in patients during and after cancer chemotherapy, and future perspectives for the management of such patients.

ConclusionOne year of trastuzumab increases the risk of cardiac events, though most consist of asymptomatic or mildly symptomatic LVEF drops. Adjuvant trastuzumab should be considered a safe treatment from a cardiac standpoint for most patients. Trastuzumab-associated cardiotoxicity is the main cause of discontinuation and further research is needed to individualize prevention and management.

Left ventricular systolic dysfunction (LVSD) and overt heart failure are well known manifestations of chemotherapy-induced cardiotoxicity. The development of LVSD is clinically significant because it can impact the delivery of lifesaving chemotherapy and increase the risk of developing heart failure, compromising quality of life and survival years after cure of the cancer. Cancer treatment –related cardiomyopathy is most commonly associated with anthracyclines and trastuzumab. Several interventions have been identified to prevent cancer-induced cardiomyopathy. Anthracyclines is a major culprit, and prevention strateg...

ConclusionsA high incidence of CV events, with no apparent correlation with CV comorbidities or risk factors, was observed.

ConclusionAdjuvant CT-P6 demonstrated comparable efficacy and safety to trastuzumab at 1  year in patients with HER2-positive EBC, supporting CT-P6 and trastuzumab comparability.

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

The nuclear DNA encoding near all of the protein machinery necessary to cell function is constantly damaged and constantly repaired. The repair mechanisms are highly efficient, and are backed up by numerous other systems intended to destroy cells that suffer particularly critical DNA damage, mutations that can lead to cancer or severe dysfunction. Nonetheless, damage accumulates. Near all of this damage is irrelevant, as it occurs randomly in single somatic cells with a limited life span, in genes that the cell isn't using. Unfortunately, there are ways for DNA damage to become significant. The first is obviously ca...

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.

In this study, we used large-scale electronic health records data from multiple linked UK databases to address these evidence gaps.MethodsFor this population-based cohort study, we used linked primary care, hospital, and cancer registry data from the UK Clinical Practice Research Datalink to identify cohorts of survivors of the 20 most common cancers who were 18 years or older and alive 12 months after diagnosis and controls without history of cancer, matched for age, sex, and general practice. We compared risks for a range of cardiovascular disease outcomes using crude and adjusted Cox models. We fitted interactions to in...

Anthracycline (doxorubicin) and trastuzumab treatments for cancer patients have been known to cause cardiotoxicity. The current recommendations for prevention of cardiac events from cancer chemotherapies are largely based on opinion. The American Society of Clinical Oncology recommends active screening and prevention of modifiable cardiovascular risk factors. The risk factors are defined as tobacco use, high blood pressure, high cholesterol, alcohol use, obesity, and physical inactivity. Beta-adrenergic blockers and angiotensin converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs) have been the mainstay o...

CONCLUSIONS: In vessels from adult subjects, acute treatment with Dox in clinically relevant doses caused significant impairment of coronary arteriolar function, whereas vessels from pediatric subjects showed only marginal impairment to the same stressor. This interesting finding might explain the delayed onset of future adverse CV events in children compared to adults after anthracycline therapy. PMID: 31397169 [PubMed - as supplied by publisher]
