Effect of a lifestyle intervention program's on breast cancer survivors' cardiometabolic health: Two-year follow-up.

The purpose of this study is to assess the cardiometabolic responses of a lifestyle intervention (LI) conducted at home among breast cancer (BC) survivors during the two years of COVID-19 pandemic. A 3-month LI focused on diet and exercise was performed on thirty BC survivors (women; stages 0-II; non-metastatic; aged 53.6 ± 7.6 years; non-physically active) with a risk factor related to metabolic/endocrine diseases. Anthropometrics, cardiorespiratory fitness (V˙O2max), physical activity level (PAL), adherence to the Mediterranean diet (MeDiet modified questionnaire), and several biomarkers (i.e., glycemia, insulin, insulin resistance [HOMA-IR] index, triglycerides, high- [HDL] and low- [LDL] density lipoproteins, total cholesterol, progesterone, testosterone, and hs-troponin) were evaluated before and 3-, 6-, 12-, and 24-month after the LI. Beneficial effects of the LI were observed on several variables (i.e., body mass index, waist circumference, MeDiet, PAL, V˙ O2max, glycemia, insulin, HOMA-IR index, LDL, total cholesterol, triglycerides, testosterone) after 3-month. The significant effect on Mediterranean diet adherence and V˙ O2max persisted up to the 24-month follow-up. Decreases in HOMA-IR index and triglycerides were observed up to 12-month, however did not persist afterward. This study provides evidence on the positive association between LI and cardiometabolic health in BC survivors.

[ANMCO statement: Uric acid and cardiovascular disease: evidence and therapeutic approach]. / Statement ANMCO: Acido urico e malattie cardiovascolari: evidenze e approccio terapeutico.

Pathophysiologic processes promoted by uric acid, including inflammation and oxidative stress, play a key role in the pathogenesis of several cardiovascular diseases. Furthermore, a number of epidemiological studies have shown an association between uric acid plasma levels and multiple cardiovascular risk factors. This ANMCO statement provides an update on available evidence regarding the association between elevated plasma uric acid levels and cardiovascular disease risk and the safety and efficacy of uric acid lowering agents (allopurinol and febuxostat) used in patients with urate crystal deposits. In addition, it summarizes practical indications for the use of these drugs in at-risk patients or in patients with cardiovascular disease.

Movement and health beyond care, MoviS: study protocol for a randomized clinical trial on nutrition and exercise educational programs for breast cancer survivors.

BACKGROUND: Breast cancer (BC) is the most common invasive cancer in women, and exercise can significantly improve the outcomes of BC survivors. MoviS (Movement and Health Beyond Care) is a randomized controlled trial aimed to evaluate the potential health benefits of exercise and proper nutritional habits. This study aims to assess the efficacy of aerobic exercise training in improving quality of life (QoL) and health-related factors in high-risk BC. METHODS: One hundred seventy-two BC survivor women, aged 30-70 years, non-metastatic, stage 0-III, non-physically active, 6-12 months post-surgery, and post chemo- or radiotherapy, will be recruited in this study. Women will be randomly allocated to the intervention arm (lifestyle recommendations and MoviS Training) or control arm (lifestyle recommendations). The MoviS training consists of 12 weeks of aerobic exercise training (2 days/week of supervised and 1 day/week of unsupervised exercise) with a progressive increase in exercise intensity (40-70% of heart rate reserve) and duration (20-60 min). Both arms will receive counseling on healthy lifestyle habits (nutrition and exercise) based on the World Cancer Research Fund International (WCRF) 2018 guidelines. The primary outcome is the improvement of the QoL. The secondary outcomes are improvement of health-related parameters such as Mediterranean diet adherence, physical activity level, flexibility, muscular fitness, fatigue, cardiorespiratory fitness (estimated maximal oxygen uptake), echocardiographic parameters, heart rate variability (average of the standard deviations of all 5 min normal to normal intervals (ASDNN/5 min) and 24 h very low and low frequency), and metabolic, endocrine, and inflammatory serum biomarkers (glycemia, insulin resistance, progesterone, testosterone, and high-sensitivity C-reactive protein). DISCUSSION: This trial aims to evaluate if supervised exercise may improve QoL and health-related factors of BC survivors with a high risk of recurrence. Findings from this project could provide knowledge improvement in the field of exercise oncology through the participation of a multidisciplinary team that will provide a coordinated program of cancer care to improve healthcare quality, improve prognosis, increase survival times and QoL, and reduce the risk of BC recurrence.

Physical activity and the heart: from well-established cardiovascular benefits to possible adverse effects.

The favorable effects of physical activity on the cardiovascular system have been well described in scientific literature. Physical activity reduces cardiovascular morbidity and mortality in both healthy subjects and in patients with cardiovascular disease. However, different intensity levels of physical activity have a different impact on the cardiovascular system. Some data support the hypothesis of a "physical activity paradox": repetitive exposure to vigorous physical activity may induce biological effects that counteract the benefits of moderate intensity levels of physical activity. In this review, we report the main effects of acute and chronic physical activity on the cardiovascular system and we summarize the biochemical mechanisms that may explain these effects.

Effects of a Home-Based Lifestyle Intervention Program on Cardiometabolic Health in Breast Cancer Survivors during the COVID-19 Lockdown.

This study aimed to evaluate the cardiometabolic effects of a home-based lifestyle intervention (LI) in breast cancer survivors (BCSs) during the COVID-19 lockdown. In total, 30 BCSs (women; stages 0-II; non-metastatic; aged 53.5 ± 7.6 years; non-physically active; normal left ventricular systolic function) with a risk factor for recurrence underwent a 3-month LI based on nutrition and exercise. Anthropometrics, Mediterranean diet adherence, physical activity level (PAL), cardiorespiratory fitness (VO2max), echocardiographic parameters, heart rate variability (average standard deviation of NN intervals (ASDNN/5 min) and 24 h very- (24 hVLF) and low-frequency (24 hLF)), and metabolic, endocrine, and inflammatory serum biomarkers (glycemia, insulin resistance, progesterone, testosterone, and high-sensitivity C-reactive protein (hs-CRP)) were evaluated before (T0) and after (T1) the LI. After the LI, there were improvements in: body mass index (kg/m2: T0 = 26.0 ± 5.0, T1 = 25.5 ± 4.7; p = 0.035); diet (Mediet score: T0 = 6.9 ± 2.3, T1 = 8.8 ± 2.2; p < 0.001); PAL (MET-min/week: T0 = 647 ± 547, T1 = 1043 ± 564; p < 0.001); VO2max (mL·min-1·kg-1: T0 = 30.5 ± 5.8, T1 = 33.4 ± 6.8; p < 0.001); signs of diastolic dysfunction (participants: T0 = 15, T1 = 10; p = 0.007); AS-DNN/5 min (ms: T0 = 50.6 ± 14.4, T1 = 55.3 ± 16.7; p = 0.032); 24 hLF (ms2: T0 = 589 ± 391, T1 = 732 ± 542; p = 0.014); glycemia (mg/dL: T0 = 100.8 ± 11.4, T1 = 91.7 ± 11.0; p < 0.001); insulin resistance (HOMA-IR score: T0 = 2.07 ± 1.54, T1 = 1.53 ± 1.11; p = 0.005); testosterone (ng/mL: T0 = 0.34 ± 0.27, T1 = 0.24 ± 0.20; p = 0.003); hs-CRP (mg/L: T0 = 2.18 ± 2.14, T1 = 1.75 ± 1.74; p = 0.027). The other parameters did not change. Despite the home-confinement, LI based on exercise and nutrition improved cardiometabolic health in BCSs.

The present position statement reports the most recent epidemiological data on acute coronary syndrome in the setting of drug abuse, describes the main pathophysiological mechanisms underlying coronary artery disease and acute events in these patients, and provides practical recommendations on management and an overview of prognosis.

Reduction in acute coronary syndromes during coronavirus disease 2019 global pandemic: data from the Marche region of Italy.

AIMS: During the novel severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019) pandemic, a worldwide reduction in total acute coronary syndrome (ACS) has been reported. In early 2020, Italy became the most affected country and national lockdown was declared early on in March. We described trends in ACS from all the Marche coronary catheterization laboratories (CCL) during the global pandemic. METHODS: Retrospective study of all consecutive patients admitted to the four regional CCL. The coronavirus disease 2019 period (20 February 2020 to 15 April 2020) was compared with the interyear control period (1 January 2020 to 19 February 2020) and to the intrayear control period (20 February 2019 to 15 April 2019). All patients with an initial diagnosis of ACS were included in the analysis, and further stratified into ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI)/unstable angina. RESULTS: A total of 1239 patients were enrolled. Daily incidence of ACS was 6.1, 6.3 and 4.5 for the interyear control period, the intrayear control period and the case period, respectively. There was no difference in overall STEMI daily incidence while NSTEMI/unstable angina fell from 3.6 and 3.3-1.8 during the case period (P = 0.01). Incidence rate ratios were significantly lower when the case period was compared with the intrayear control period (incidence rate ratios: 0.49, 95% confidence interval 0.41-0.59, P = 0.001) and the interyear control period (incidence rate ratios: 0.67, 95% confidence interval 0.50-0.90, P = 0.008). CONCLUSION: During the global pandemic there was a significant reduction in total ACS and NSTEMI in the Marche region. Unlike previous reports, there was no difference in overall access to CCL for STEMI during the same period.

Temporal Trends and Temperature-Related Incidence of Electrical Storm: The TEMPEST Study (Temperature-Related Incidence of Electrical Storm).

BACKGROUND: The occurrence of ventricular tachyarrhythmias seems to follow circadian, daily, and seasonal distributions. Our aim is to identify potential temporal patterns of electrical storm (ES), in which a cluster of ventricular tachycardias or ventricular fibrillation, negatively affects short- and long-term survival. METHODS AND RESULTS: The TEMPEST study (Circannual Pattern and Temperature-Related Incidence of Electrical Storm) is a patient-level, pooled analysis of previously published data sets. Study selection criteria included diagnosis of ES, absence of acute coronary syndrome as the arrhythmic trigger, and ≥10 patients included. At the end of the selection and collection processes, 5 centers had the data set from their article pooled into the present registry. Temperature data and sunrise and sunset hours were retrieved from Weather Underground, the largest weather database available online. Total sample included 246 patients presenting with ES (221 men; age: 65±9 years). Each ES episode included a median of 7 ventricular tachycardia/ventricular fibrillation episodes. Fifty-nine percent of patients experienced ES during daytime hours (P<0.001). The prevalence of ES was significantly higher during workdays, with Saturdays and Sundays registering the lowest rates of ES (10.4% and 7.2%, respectively, versus 16.5% daily mean from Monday to Friday; P<0.001). ES occurrence was significantly associated with increased monthly temperature range when compared with the month before (P=0.003). CONCLUSIONS: ES incidence is not homogenous over time but seems to have a clustered pattern, with a higher incidence during daytime hours and working days. ES is associated with an increase in monthly temperature variation. CLINICAL TRIAL REGISTRATION: https://www.crd.york.ac.uk. Unique identifier: CRD42013003744.

IntErnationaL eLeCTRicAl storm registry (ELECTRA): Background, rationale, study design, and expected results.

Electrical storm (ES) is defined as three or more episodes of ventricular fibrillation (VF) or ventricular tachycardia (VT) within 24 h and is associated with an increased cardiac and all-cause mortality. ES is a full arrhythmic emergency, its prevalence steadily increasing along with the number of implantable cardioverter-defibrillator implanted every year in developed countries. Nowadays, little evidence exists regarding clinical predictors of ES and their potential association on mortality and heart failure (HF), nor optimal pharmacological and non-pharmacological treatment has ever been codified. The intErnationaL eLeCTRicAl storm registry (ELECTRA) is a multicentre, observational, prospective clinical study with two major aims. First, to create an international database on ES encompassing clinical features, pharmacological management, and interventional treatment strategies. Second, to describe mortality and rehospitalization rates in patients with ES over a long follow-up. The primary endpoint is all-cause mortality 3 years after the ES index event. The main secondary endpoint is hospitalization for all causes 3 years after the ES index event. Other secondary endpoints includes ES recurrences, unclustered VTs/VFs recurrences, and hospitalizations for HF worsening. A minimum of 500 patients will be included in the registry, and all patients will be followed-up for a minimum of three years. The present paper describes the background and current rationale of the ELECTRA study and details the study design, from enrolment strategy to data collection methods to planned data analysis. A brief overview of the expected results and their potential clinical and research implications will also be presented (NCT02882139).

Electrical storm and heart failure worsening in implantable cardiac defibrillator patients.

AIMS: In patients with an implantable cardiac defibrillator (ICD), electrical storm (ES) is associated with increased sudden and non-sudden cardiac mortality, the latter largely due to worsening heart failure (HF). Aim of this study is to test the association between ES and impending pump failure in patients with known chronic HF and ICD. METHODS AND RESULTS: Inclusion criteria were a previous history of chronic HF, former ICD implant, and hospital admission for HF worsening, or ES, or unclustered ventricular tachyarrhythmias (VTs/VFs). Patients with concomitant stable HF or HF worsening due to another specific cause were excluded. Primary endpoint was all cause mortality. Main secondary endpoint was time to first rehospitalization. Prospective, observational study on 146 patients: 34 with ES, 30 with unclustered VTs/VFs, and 82 with HF worsening. During the 5 years of follow-up, there was no significant difference between survival estimates between ES and HF worsening (P = 0.7), while both were significantly lower than survival of unclustered VT/VF patients (all log rank P < 0.05). Hospitalization-free time was significantly lower in both the ES group and in the HF worsening group when compared with unclustered VT/VF patients (all log rank P < 0.05). There was no significant difference between hospitalization estimates between ES and HF worsening. CONCLUSION: Heart failure patients admitted for ES have major similarities with patients admitted for HF clinical decompensation such as similar survival, cause of death and time to first rehospitalization. There is evidence suggesting that, in this population, ES could be considered as a clinical manifestation of HF worsening.

Role of electrical storm as a mortality and morbidity risk factor and its clinical predictors: a meta-analysis.

AIMS: Electrical storm (ES) is a devastating and life-threatening event in clinical practice, but its real weight as a risk factor and its clinical predictors remain unclear. Our objective was to evaluate ES as a mortality and morbidity risk factor and to define the clinical variables associated with ES. METHODS AND RESULTS: The meta-analysis was performed according to the PRISMA guidelines. At the end of the selection process, 13 studies were collected and included in the quantitative analysis. Mortality and morbidity due to ES were assessed. The most acknowledged ES predictors were taken into account in separate sub-analyses. The whole cohort included 5912 patients (857 with ES). Risk of death was increased in the ES group [risk ratio (RR) 3.15; 95% confidence interval (CI) 2.22-4.48]. Electrical storm was also associated with increased composite risk of all-cause death, cardiac transplantation, and hospitalization for acute heart failure (RR 3.39; 95% CI 2.31-4.97). These results were confirmed by comparing the ES group with patients with or without previous unclustered episodes of ventricular arrhythmias. Moreover, implantable cardioverter-defibrillator (ICD) for secondary prevention, lower ejection fraction, monomorphic ventricular tachycardia as triggering arrhythmia, and class I anti-arrhythmic drugs therapy were all associated with ES. CONCLUSION: Electrical storm is a strong mortality risk factor and it is associated with an increased combined risk of death, heart transplantation, and hospitalization for heart failure. Implantable cardioverter-defibrillator for secondary prevention, monomorphic ventricular tachycardia as triggering arrhythmia, lower ejection fraction, and class I anti-arrhythmic drugs therapy are all associated with ES and could be used to define specific populations with higher risk to develop ES.
