COVID-19 vaccination in patients with heart failure: a position paper of the Heart Failure Association of the European Society of Cardiology.

Patients with heart failure (HF) who contract SARS-CoV-2 infection are at a higher risk of cardiovascular and non-cardiovascular morbidity and mortality. Regardless of therapeutic attempts in COVID-19, vaccination remains the most promising global approach at present for controlling this disease. There are several concerns and misconceptions regarding the clinical indications, optimal mode of delivery, safety and efficacy of COVID-19 vaccines for patients with HF. This document provides guidance to all healthcare professionals regarding the implementation of a COVID-19 vaccination scheme in patients with HF. COVID-19 vaccination is indicated in all patients with HF, including those who are immunocompromised (e.g. after heart transplantation receiving immunosuppressive therapy) and with frailty syndrome. It is preferable to vaccinate against COVID-19 patients with HF in an optimal clinical state, which would include clinical stability, adequate hydration and nutrition, optimized treatment of HF and other comorbidities (including iron deficiency), but corrective measures should not be allowed to delay vaccination. Patients with HF who have been vaccinated against COVID-19 need to continue precautionary measures, including the use of facemasks, hand hygiene and social distancing. Knowledge on strategies preventing SARS-CoV-2 infection (including the COVID-19 vaccination) should be included in the comprehensive educational programmes delivered to patients with HF.

Role of serum biomarkers in cancer patients receiving cardiotoxic cancer therapies: a position statement from the Cardio-Oncology Study Group of the Heart Failure Association and the Cardio-Oncology Council of the European Society of Cardiology.

Serum biomarkers are an important tool in the baseline risk assessment and diagnosis of cardiovascular disease in cancer patients receiving cardiotoxic cancer treatments. Increases in cardiac biomarkers including cardiac troponin and natriuretic peptides can be used to guide initiation of cardioprotective treatments for cancer patients during treatment and to monitor the response to cardioprotective treatments, and they also offer prognostic value. This position statement examines the role of cardiac biomarkers in the management of cancer patients. The Cardio-Oncology Study Group of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) in collaboration with the Cardio-Oncology Council of the ESC have evaluated the current evidence for the role of cardiovascular biomarkers in cancer patients before, during and after cardiotoxic cancer therapies. The characteristics of the main two biomarkers troponin and natriuretic peptides are discussed, the link to the mechanisms of cardiovascular toxicity, and the evidence for their clinical use in surveillance during and after anthracycline chemotherapy, trastuzumab and HER2-targeted therapies, vascular endothelial growth factor inhibitors, proteasome inhibitors, immune checkpoint inhibitors, cyclophosphamide and radiotherapy. Novel surveillance clinical pathways integrating cardiac biomarkers for cancer patients receiving anthracycline chemotherapy or trastuzumab biomarkers are presented and future direction in cardio-oncology biomarker research is discussed.

Role of cardiovascular imaging in cancer patients receiving cardiotoxic therapies: a position statement on behalf of the Heart Failure Association (HFA), the European Association of Cardiovascular Imaging (EACVI) and the Cardio-Oncology Council of the European Society of Cardiology (ESC).

Cardiovascular (CV) imaging is an important tool in baseline risk assessment and detection of CV disease in oncology patients receiving cardiotoxic cancer therapies. This position statement examines the role of echocardiography, cardiac magnetic resonance, nuclear cardiac imaging and computed tomography in the management of cancer patients. The Imaging and Cardio-Oncology Study Groups of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) in collaboration with the European Association of Cardiovascular Imaging (EACVI) and the Cardio-Oncology Council of the ESC have evaluated the current evidence for the value of modern CV imaging in the cardio-oncology field. The most relevant echocardiographic parameters, including global longitudinal strain and three-dimensional ejection fraction, are proposed. The protocol for baseline pre-treatment evaluation and specific surveillance algorithms or pathways for anthracycline chemotherapy, HER2-targeted therapies such as trastuzumab, vascular endothelial growth factor tyrosine kinase inhibitors, BCr-Abl tyrosine kinase inhibitors, proteasome inhibitors and immune checkpoint inhibitors are presented. The indications for CV imaging after completion of oncology treatment are considered. The typical consequences of radiation therapy and the possibility of their identification in the long term are also summarized. Special populations are discussed including female survivors planning pregnancy, patients with carcinoid disease, patients with cardiac tumours and patients with right heart failure. Future directions and ongoing CV imaging research in cardio-oncology are discussed.

Baseline cardiovascular risk assessment in cancer patients scheduled to receive cardiotoxic cancer therapies: a position statement and new risk assessment tools from the Cardio-Oncology Study Group of the Heart Failure Association of the European Society of Cardiology in collaboration with the International Cardio-Oncology Society.

This position statement from the Heart Failure Association of the European Society of Cardiology Cardio-Oncology Study Group in collaboration with the International Cardio-Oncology Society presents practical, easy-to-use and evidence-based risk stratification tools for oncologists, haemato-oncologists and cardiologists to use in their clinical practice to risk stratify oncology patients prior to receiving cancer therapies known to cause heart failure or other serious cardiovascular toxicities. Baseline risk stratification proformas are presented for oncology patients prior to receiving the following cancer therapies: anthracycline chemotherapy, HER2-targeted therapies such as trastuzumab, vascular endothelial growth factor inhibitors, second and third generation multi-targeted kinase inhibitors for chronic myeloid leukaemia targeting BCR-ABL, multiple myeloma therapies (proteasome inhibitors and immunomodulatory drugs), RAF and MEK inhibitors or androgen deprivation therapies. Applying these risk stratification proformas will allow clinicians to stratify cancer patients into low, medium, high and very high risk of cardiovascular complications prior to starting treatment, with the aim of improving personalised approaches to minimise the risk of cardiovascular toxicity from cancer therapies.

Mechanisms of the Multitasking Endothelial Protein NRG-1 as a Compensatory Factor During Chronic Heart Failure.

Heart failure is a complex syndrome whose phenotypic presentation and disease progression depends on a complex network of adaptive and maladaptive responses. One of these responses is the endothelial release of NRG (neuregulin)-1-a paracrine growth factor activating ErbB2 (erythroblastic leukemia viral oncogene homolog B2), ErbB3, and ErbB4 receptor tyrosine kinases on various targets cells. NRG-1 features a multitasking profile tuning regenerative, inflammatory, fibrotic, and metabolic processes. Here, we review the activities of NRG-1 on different cell types and organs and their implication for heart failure progression and its comorbidities. Although, in general, effects of NRG-1 in heart failure are compensatory and beneficial, translation into therapies remains unaccomplished both because of the complexity of the underlying pathways and because of the challenges in the development of therapeutics (proteins, peptides, small molecules, and RNA-based therapies) for tyrosine kinase receptors. Here, we give an overview of the complexity to be faced and how it may be tackled.

Recent advances in cardio-oncology: a report from the 'Heart Failure Association 2019 and World Congress on Acute Heart Failure 2019'.

While anti-cancer therapies, including chemotherapy, immunotherapy, radiotherapy, and targeted therapy, are constantly advancing, cardiovascular toxicity has become a major challenge for cardiologists and oncologists. This has led to an increasing demand of cardio-oncology units in Europe and a growing interest of clinicians and researchers. The Heart Failure 2019 meeting of the Heart Failure Association of the European Society of Cardiology in Athens has therefore created a scientific programme that included four dedicated sessions on the topic along with several additional lectures. The major points that were discussed at the congress included the implementation and delivery of a cardio-oncology service, the collaboration among cardio-oncology experts, and the risk stratification, prevention, and early recognition of cardiotoxicity. Furthermore, sessions addressed the numerous different anti-cancer therapies associated with cardiotoxic effects and provided guidance on how to treat cancer patients who develop cardiovascular disease before, during, and after treatment.

Combination Antihypertensive Therapy with Perindopril and Indapamide in Patients with Essential Hypertension: Effect on Endothelial and Cognitive Markers of Vascular Improvement.

INTRODUCTION: The objective of this study was to assess the impact of a single-pill combination (SPC) of perindopril/indapamide (PER/IND) at full doses (10/2.5 mg) on endothelial and cognitive function as a clinical intermediate marker of vascular improvement. METHODS: This open-label, uncontrolled, observational study enrolled 30 patients (20 females and 10 males) with grade II-III uncontrolled arterial hypertension (SBP/DBP ≥ 160/100 mmHg) and no evidence of cerebrovascular disease. All patients underwent assessment of macro- and microvascular endothelial function parameters at baseline and after 12 months of treatment with SPC PER/IND using photoplethysmography and video capillaroscopy. Cognitive function was assessed using the Montreal Cognitive Assessment scale (MoCA). RESULTS: All patients (mean age 60.06 ± 10.19 years) were at high risk for cardiovascular events: mean body mass index (BMI) 31.2 ± 3.9 kg/m2, 33% diagnosed with coronary artery disease angina class I, 30% with impaired glucose tolerance, and 7% with type 2 diabetes. Impaired endothelial function was observed at the both micro- and macrovascular levels. Endothelial function parameters improved after 12-month treatment with SPC PER/IND with an increase in occlusion index from 1.4 to 1.8 (P < 0.00005) and phase shift from 5.0 to 10.8 (P < 0.00001); all values achieved levels in the normal range. Resting capillary network density (CND) increased from 44.8 to 52 cap/mm2 (P < 0.00007), and CND after a venous occlusion test increased from 55 to 61 cap/mm2 (P < 0.006). Signs of cognitive impairment were present at baseline with a mean MoCA score of 23 (normal cognitive function score ≥ 26), but improved after 12-month treatment with a mean MoCA score of 27 (P< 0.0001). Treatment was well tolerated. CONCLUSION: SPC PER/IND at full doses for 12 months improves endothelial function, structural and functional parameters of the microcirculation, as well as cognitive function in patients with arterial hypertension at high cardiovascular risk.

Modern-day cardio-oncology: a report from the 'Heart Failure and World Congress on Acute Heart Failure 2018'.

During the 'Heart Failure and World Congress on Acute Heart Failure 2018', many sessions and lectures focused on cardio-oncology. This important field of research is constantly growing, and therefore, a great amount of time during the congress focused on it. Prevention and early recognition of side effects is very important in cancer patients. One of the most common and potentially severe problems during antineoplastic therapy is cardiotoxicity. Hence, cardio-oncology is vital in managing cancer patients. This paper will summarize the topics discussed in three main sessions and many additional lectures throughout the 'Heart Failure and World Congress on Acute Heart Failure 2018'. The covered topics included pathophysiological mechanisms in the development of heart failure, risk factors, and early signs of cardiotoxicity detectable with different circulating and imaging biomarkers, as well as cardioprotective treatments recommended by different guidelines and position papers.

Cancer diagnosis in patients with heart failure: epidemiology, clinical implications and gaps in knowledge.

Cancer and heart failure (HF) are common medical conditions with a steadily rising prevalence in industrialized countries, particularly in the elderly, and they both potentially carry a poor prognosis. A new diagnosis of malignancy in subjects with pre-existing HF is not infrequent, and challenges HF specialists as well as oncologists with complex questions relating to both HF and cancer management. An increased incidence of cancer in patients with established HF has also been suggested. This review paper summarizes the epidemiology and the prognostic implications of cancer occurrence in HF, the impact of pre-existing HF on cancer treatment decisions and the impact of cancer on HF therapeutic options, while providing some practical suggestions regarding patient care and highlighting gaps in knowledge.

Antioxidants decreases the intensification of low density lipoprotein in vivo peroxidation during therapy with statins.

The oxidative modification of low density lipoprotein (LDL) is thought to play an important role in atherogenesis. Drugs of beta-hydroxy-beta-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) family are usually used as a very effective lipid-lowering preparations but they simultaneously block biosynthesis of both cholesterol and ubiquinone Q10 (coenzyme Q), which is an intermediate electron carrier in the mitochondrial respiratory chain. It is known that reduced form of ubiquinone Q10 acts in the human LDL as very effective natural antioxidant. Daily per os administration of HMG-CoA reductase inhibitor simvastatin to rats for 30 day had no effect on high-energy phosphates (adenosin triphosphate, creatine phosphate) content in liver but decreased a level of these substances in myocardium. We study the Cu2+-mediated susceptibility of human LDL to oxidation and the levels of free radical products of LDL lipoperoxidation in LDL particles from patients with atherosclerosis after 3 months treatment with natural antioxidants vitamin E as well as during 6 months administration of HMG-CoA reductase inhibitors such as pravastatin and cerivastatin in monotherapy and in combination with natural antioxidant ubiquinone Q10 or synthetic antioxidant probucol in a double-blind placebo-controlled trials. The 3 months of natural antioxidant vitamin E administration (400 mg daily) to patients did not increase the susceptibility of LDL to oxidation. On the other hand, synthetic antioxidant probucol during long-time period of treatment (3-6 months) in low-dose (250 mg daily) doesn't change the lipid metabolism parameters in the blood of patients but their high antioxidant activity was observed. Really, after oxidation of probucol-contained LDL by C-15 animal lipoxygenase in these particles we identified the electron spin resonance signal of probucol phenoxyl radical that suggests the interaction of LDL-associated probucol with lipid radicals in vivo. We observed that 6 months treatment of patients with pravastatine (40 mg daily) or cerivastatin (0.4 mg daily) was followed by sufficiently accumulation of LDL lipoperoxides in vivo. In contrast, the 6 months therapy with pravastatin in combination with ubiquinone Q10 (60 mg daily) sharply decreased the LDL initial lipoperoxides level whereas during treatment with cerivastatin in combination with probucol (250 mg daily) the LDL lipoperoxides concentration was maintained on an invariable level. Therefore, antioxidants may be very effective in the prevention of atherogenic oxidative modification of LDL during HMG-CoA reductase inhibitors therapy.
