Filter by:This study aimed to investigate the role of impedance cardiography (ICG) in evaluating hemodynamic changes during the 6-minute walk test (6MWT) in patients with locally advanced non-small cell lung cancer (LA-NSCLC) who underwent combined concurrent chemoradiotherapy (CCRT) and immunotherapy. Additionally, It sought to analyze the predictive significance of cardiac parameters to both treatment toxicity and survival prognosis.
Cancer therapy-related cardiac dysfunction (CTRCD) is when the heart's ability to pump oxygenated blood to the body is compromised. It is a side effect of cancer therapy which can occur as commonly as in 1 in 5 patients. When this occurs, heart failure medications are started to protect the heart from progressing to heart failure. With early detection and treatment, heart function recovers to normal in >80% of patients. Unfortunately, heart failure medications are associated with an undesirable long-term pill burden, financial costs, and side-effects (e.g., dizziness and fatigue). As a result, cancer survivors frequently ask if they can safely stop their heart failure medications once their heart function has returned to normal. Currently there is no scientific evidence in this area of Cardio-Oncology. To address this knowledge gap, the investigators have designed a randomized control trial to assess the safety of stopping heart failure medication in patients with CTRCD and recovered heart function. The investigators will enrol patients who have completed their cancer therapy and are on heart medications for their CTRCD, which has now normalized. The investigators will randomize patients with no other reasons to continue heart failure medications (e.g., kidney disease) to continuing or stopping their heart medications safely. All patients will undergo a cardiac MRI at baseline, 1 and 5 years with safety assessments at 6-8 weeks, 6 and 9 months and 3 and 5 years. The investigators will determine if stopping medications is non-inferior to continuing medications by counting the numbers of patients who develop heart dysfunction by 1 year in each group.
Childhood cancer survivors are at an increased risk of cardiac toxicity due to prior anti-cancer therapy. However, adherence to cardiac screening in this population remains low. This study aims to assess the feasibility of an mHealth motivational interviewing platform called Computerized Authoring Intervention Software (CIAS) in childhood cancer survivors. Participants will be recruited from the Childhood Cancer Survivorship Study.
Spinal anesthesia remains a mainstay in lower limbs- as in day-case surgeries as well. It consists in injecting a local anesthetic drug into the intrathecal space of a patient's spinal canal. To achieve a suitable sensory and motor block for elective or emergent surgery, the anesthetist must adapt his choice of local anesthetic to the surgery's requirements and the patient's comorbidities, too. Spinal anesthesia is often associated with adverse cardiovascular events, notably hypotension which is a major concern in current anesthetic practice, especially in specific patient populations. Spinal induced hypotension is reported to be commonly related to the sympathetic block level and may be linked to perioperative cardiac and renal complications. Several mechanisms might play a role in the incidence of perioperative hypotension after spinal puncture. A decrease in peripheric systemic vascular resistance from arterial vasodilatation, a reduction of cardiac output due to a decrease in preload from a redistribution of venous blood into lower limbs or even an occurrence or increment of cardiac dysfunction, might compound proper blood flow towards noble organs such as brain, heart and kidneys. Spinal induced hypotension may also be related to a direct reduction of cardiac contractibility by the local anesthetic injection. Compensating mechanisms might be inhibited depending on the level of sympathetic blockade, usually related to the dose of the local anesthetic. Former studies found that intrinsic left ventricular depression might occur during spinal anesthesia as left ventricular volumes per se remain stable. One noticed that diastolic and systolic function (i.e., ventricular outflow tract velocity) decreased significantly after intrathecal levobupivacaine plus fentanyl injection based on transthoracic ultrasound assessment. Other authors use Pro-Brain Natriuretic Peptide to assess myocardial stress induced by surgery and anesthetic management. Other serum markers such as Cortisol, Adreno Cortico-Trope Hormone, Angiotensin are identified to screen and monitor myocardial stress as for instance acute myocardial dysfunction. Hyperbaric prilocaine is an intermediate-acting local anesthetic, whereas bupivacaine may be intermediate- or long-acting depending on the employed dose. Both drugs provide comparable sensory and motor block that meet the anesthesia level requirements in various surgical procedures. In regard to the hemodynamic effects, hypotension has been largely reported following hyperbaric bupivacaine in a dose-dependent way. However, discrepancy exists between the rare studies having investigated prilocaine's effects, probably related to the methodology and the employed doses. Moreover, the hemodynamics effects of these local anesthetics have been barely specifically investigated in a non-cesarean section context. The aim of this study is to compare the cardiovascular effects inflicted by hyperbaric prilocaine and bupivacaine under spinal anesthesia. Cardiovascular response will be assessed by non-invasive hemodynamic monitoring whereas metabolic stress will be evaluated using serum stress markers.
This study proposes that the addition of statins reduces the treatment delays or early discontinuations secondary to cardiotoxicity in patients with Stage I-III HER2 positive breast being treated with anti-HER2 therapy.
Breast cancer is the most commonly cancer in women in the overall global population. According to the World Cancer Research Fund International, there were more than 2.25 million new cases of breast cancer in women in 2020. Although the modern treatment strategies, based on the complex care, which consists of surgery, radiotherapy, hormone therapy, and targeted chemotherapy directed at specific cancer molecules have substantially reduced the risk of death due to breast cancer, their wide adoption results in the wider prevalence of cardiotoxicity, defined as either symptomatic heart failure, or asymptomatic contractile dysfunction. The occurrence of cardiotoxicity induced by anti-cancer therapies is estimated at 5-15%, and its development is the primary cause of therapy termination, which significantly reduces the probability of the efficacy of treatment. Several attempts have been made to determine the efficacious preventive strategy, which could diminish the risk of cancer-therapy induced cardiotoxicity. The results of the prior studies indicated a trend towards lower risk of troponin elevation, or left ventricular contractile dysfunction with the introduction of drugs interfering with the renin-angiotensin-aldosterone (RAA) axis, which constitute the primary treatment modality in heart failure with reduced ejection fraction (HFrEF). Sacubitril/valsartan, the novel therapeutic agent, has been demonstrated to significantly improve prognosis in patients with HFrEF. Prior retrospective, small, single-center studies have shown that treatment with sacubitril/valsartan may reduce the risk of cancer-therapy induced cardiotoxicity, or reverse contractile dysfunction caused by anti-cancer therapy. However, no large randomized data confirmed these findings. Therefore, the Sacubitril/Valsartan in PriMAry preventIoN of the cardiotoxicity of systematic breaST canceR trEAtMent) study, has been designed to verify, whether the preventive use of sacubitril/valsartan administered in the doses recommended in patients with HFrEF in breast cancer patients undergoing adjuvant chemotherapy with anthracyclines or anthracyclines and HER-2 monoclonal antibodies, will reduce the incidence of cardiotoxicity defined as impaired left ventricular systolic function on cardiac magnetic resonance imaging (MRI). In the trial, a total of 480 patients with histologically confirmed breast cancer, who are eligible for chemotherapy with anthracyclines or anthracyclines and HER-2 monoclonal antibodies, will undergo 1:1 randomization to either preventive treatment with sacubitril/valsartan or placebo. The patients will be followed for 24 months, and will have repetitive efficacy and safety examinations, including echocardiography, MRI, electrocardiography including 24-h Holter monitoring, blood tests, functional capacity tests and quality of life assessment.
Patients with loco-regional NSCLC planned for curative treatment with chemoradiotherapy will be invited to participate in a prospective study; besides routine treatment, the patients will be followed with an ECG and cardiac MR for at least two years after radiotherapy treatment.
This is a prospective, multicenter, cohort study aiming to explore the cardiotoxicity of targeted therapy for HER-2 positive breast cancer patients who lives in high altitude area. One hundred and thirty two HER-2 positive breast cancer patients who will receive neoadjuvant, adjuvant, or palliative targeted therapy will be enrolled. The cardiotoxicity of targeted therapy will be observed and recorded during the treatment and one year after the end of treatment. The subjects will be stratified by age, baseline cardiac risk factors, and anthracyclines.
