RESUMO
Magnetic resonance (MR) imaging (MRI) is routinely used to evaluate organ morphology and pathology in the human body at rest or in combination with pharmacological stress as an exercise surrogate. With MR during actual physical exercise, we can assess functional characteristics of tissues and organs under real-life stress conditions. This is particularly relevant in patients with limited exercise capacity or exercise intolerance, and where complaints typically present only during physical activity, such as in neuromuscular disorders, inherited metabolic diseases, and heart failure. This review describes practical and physiological aspects of exercise MR of skeletal muscles, the heart, and the brain. The acute effects of physical exercise on these organs are addressed in the light of various dynamic quantitative MR readouts, including phosphorus-31 MR spectroscopy (31P-MRS) of tissue energy metabolism, phase-contrast MRI of blood flow and muscle contraction, real-time cine MRI of cardiac performance, and arterial spin labeling MRI of muscle and brain perfusion. Exercise MR will help advancing our understanding of underlying mechanisms that contribute to exercise intolerance, which often proceed structural and anatomical changes in disease. Its potential to detect disease-driven alterations in organ function, perfusion, and metabolism under physiological stress renders exercise MR stress testing a powerful noninvasive imaging modality to aid in disease diagnosis and risk stratification. Although not yet integrated in most clinical workflows, and while some applications still require thorough validation, exercise MR has established itself as a comprehensive and versatile modality for characterizing physiology in health and disease in a noninvasive and quantitative way. EVIDENCE LEVEL: 5 TECHNICAL EFFICACY: Stage 1.
RESUMO
BACKGROUND: Little is known about the association between fear of movement (kinesiophobia) and objectively measured physical activity (PA), the first 12 weeks after cardiac hospitalization. PURPOSE: To assess the longitudinal association between kinesiophobia and objectively measured PA and to assess the factor structure of kinesiophobia. METHODS: We performed a longitudinal observational study. PA was continuously measured from hospital discharge to 12 weeks using the Personal Activity Monitor. The PAM measures time spent per day in PA-intensity categories: light, moderate and heavy. Kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK) at four time points (hospital discharge, 3, 6 and 12 weeks). The longitudinal association between PA-intensity and kinesiophobia was studied with a random intercept cross lagged panel model (RI-CLPM). A RI-CLPM estimates effects from kinesiophobia on objectively measured PA and vice versa (cross-over effects), and autoregressive effects (e.g. kinesiophobia from one occasion to the next). RESULTS: In total, 116 patients (83.6% male) with a median age of 65.5 were included in this study. On no occasion did we find an effect of kinesiophobia on PA and vice versa. Model fit for the original model was poor (X2: = 44.646 P<0.001). Best model fit was found for a model were kinesiophobia was modelled as a stable between factor (latent variable) and PA as autoregressive component (dynamic process) (X2 = 27.541 P<0.12). CONCLUSION: Kinesiophobia and objectively measured PA are not associated in the first 12 weeks after hospital discharge. This study shows that kinesiophobia remained relatively stable, 12 weeks after hospital discharge, despite fluctuations in light to moderate PA-intensity.

Objective: Despite clear evidence on the effectiveness of secondary prevention, patients with coronary artery disease frequently fail to reach guideline-based risk factor targets. Integrating patients' preferences into treatment decisions has been recommended to reduce this gap. However, this requires knowledge about patient treatment preferences. Therefore, through a survey study, we aimed to explore which risk factors patients self-perceived, prioritised for improvement, and needed support with after a recent hospitalisation for coronary heart disease. Methods: A digital questionnaire was presented to patients > 18 years recently discharged (≤3 months) from an acute coronary care unit in the Netherlands (Europe). Patients could select from eight cardiovascular risk factors that they (1) self-perceived, (2) prioritised for improvement, and (3) needed support to improve. Patients' perceived risk factors were compared to those documented in the medical records. Results: Respondents (N = 254, 26 % women), mean age 64 (SD 10) years, identified 'physical inactivity' more frequently than their medical records (140 patients vs. 91 records, p < 0.001), while three other risk factors were reported with equal and four with lower frequency. 'Physical inactivity', 'overweight' and 'stress' were most frequently prioritised for improvement (82 %, 88 % and 78 %) and professional support (64 %, 50 % and 58 %), with 87 % preferring lifestyle optimisation if this would reduce drug use. Conclusions: Patients with a recent coronary event show significant disparities in identifying risk factors compared to their medical records. They tend to prefer improving lifestyle- over drug-modifiable risk factors, particularly physical inactivity, overweight and stress, and indicate the need for support in improving these factors.
RESUMO
The incidence of aortic valve stenosis (AoS) increases with age, and once diagnosed, symptomatic severe AoS has a yearly mortality rate of 25%. AoS is diagnosed with transthoracic echocardiography (TTE), however, this gold standard is time consuming and operator and acoustic window dependent. As AoS affects the arterial blood pressure waveform, AoS-specific waveform features might serve as a diagnostic tool. Aim of the present study was to develop a novel, non-invasive, AoS detection model based on blood pressures waveforms. This cross-sectional study included patients with AoS undergoing elective transcatheter or surgical aortic valve replacement. AoS was determined using TTE, and patients with no or mild AoS were labelled as patients without AoS, while patients with moderate or severe AoS were labelled as patients with AoS. Non-invasive blood pressure measurements were performed in awake patients. Ten minutes of consecutive data was collected. Several blood pressure-based features were derived, and the median, interquartile range, variance, and the 1st and 9th decile of the change of these features were calculated. The primary outcome was the development of a machine-learning model for AoS detection, investigating multiple classifiers and training on the area under the receiver-operating curve (AUROC). In total, 101 patients with AoS and 48 patients without AoS were included. Patients with AoS showed an increase in left ventricular ejection time (0.02 s, p = 0.001), a delayed maximum upstroke in the systolic phase (0.015 s, p < 0.001), and a delayed maximal systolic pressure (0.03 s, p < 0.001) compared to patients without AoS. With the logistic regression model, a sensitivity of 0.81, specificity of 0.67, and AUROC of 0.79 were found. The majority of the population without AoS was male (85%), whereas in the population with AoS this was evenly distributed (54% males). Age was significantly (5 years, p < 0.001) higher in the population with AoS. In the present study, we developed a novel model able to distinguish no to mild AoS from moderate to severe AoS, based on blood pressure features with high accuracy. Clinical registration number: The study entailing patients with TAVR treatment was registered at ClinicalTrials.gov (NCT03088787, https://clinicaltrials.gov/ct2/show/NCT03088787 ). The study with elective cardiac surgery patients was registered with the Netherland Trial Register (NL7810, https://trialsearch.who.int/Trial2.aspx?TrialID=NL7810 ).
RESUMO
INTRODUCTION: The optimal pre-participation screening strategy to identify athletes at risk for exercise-induced cardiovascular events is unknown. We therefore aimed to compare the American College of Sports Medicine (ACSM) and European Society of Cardiology (ESC) pre-participation screening strategies against extensive cardiovascular evaluations in identifying high-risk individuals among 35-50-year-old apparently healthy men. METHODS: We applied ACSM and ESC pre-participation screenings to 25 men participating in a study on first-time marathon running. We compared screening outcomes against medical history, physical examination, electrocardiography, blood tests, echocardiography, cardiopulmonary exercise testing, and magnetic resonance imaging. RESULTS: ACSM screening classified all participants as "medical clearance not necessary." ESC screening classified two participants as "high-risk." Extensive cardiovascular evaluations revealed ≥1 minor abnormality and/or cardiovascular condition in 17 participants, including three subjects with mitral regurgitation and one with a small atrial septal defect. Eleven participants had dyslipidaemia, six had hypertension, and two had premature atherosclerosis. Ultimately, three (12%) subjects had a serious cardiovascular condition warranting sports restrictions: aortic aneurysm, hypertrophic cardiomyopathy (HCM), and myocardial fibrosis post-myocarditis. Of these three participants, only one had been identified as "high-risk" by the ESC screening (for dyslipidaemia, not HCM) and none by the ACSM screening. CONCLUSION: Numerous occult cardiovascular conditions are missed when applying current ACSM/ESC screening strategies to apparently healthy middle-aged men engaging in their first high-intensity endurance sports event.

Objectives: To investigate the association between leisure time physical activity (LTPA) and MRI-based diastolic function and the mediating role of metabolic health. Methods: This cross-sectional analysis comprised 901 participants (46% women, mean age (SD): 56 (6) years (The Netherlands, 2008-2012)). LTPA was assessed via questionnaire, quantified in metabolic equivalent of tasks (METs)-minutes per week and participants underwent abdominal and cardiovascular MRI. Confirmatory factor analysis was used to construct the metabolic load factor. Piecewise structural equation model with adjustments for confounders was used to determine associations between LTPA and diastolic function and the mediating effect of metabolic load. Results: Significant differences in mitral early/late peak filling rate (E/A) ratio per SD of LTPA (men=1999, women=1870 MET-min/week) of 0.18, (95% CI= 0.03 to 0.33, p=0.021) were observed in men, but not in women: -0.01 (-0.01 to 0.34, p=0.058). Difference in deceleration time of mitral early filling (E-DT) was 0.13 (0.01 to 0.24, p=0.030) in men and 0.17 (0.05 to 0.28, p=0.005) in women. Metabolic load, including MRI-based visceral and subcutaneous adipose tissue, fasting glucose, high-density lipoprotein cholesterol and triglycerides, mediated these associations as follows: E/A-ratio of 0.030 (0.000 to 0.067, 19% mediated, p=0.047) in men but not in women: 0.058 (0.027 to 0.089, p<0.001) and E-DT not in men 0.004 (-0.012 to 0.021, p=0.602) but did in women 0.044 (0.013 to 0.057, 27% mediated, p=0.006). Conclusions: A larger amount of LTPA was associated with improved diastolic function where confirmatory factor analysis-based metabolic load partly mediated this effect. Future studies should assess whether improving indicators of metabolic load alongside LTPA will benefit healthy diastolic function even more.
RESUMO
OBJECTIVE: Low-density lipoprotein cholesterol (LDL-C) lowering constitutes a cornerstone of secondary prevention of atherosclerotic cardiovascular disease (ASCVD), yet a considerable number of patients do not achieve guideline-recommended LDLC targets. The 2016 European guidelines recommended titration of LDLC lowering medication in a set number of steps, starting with oral medication. We aimed to investigate the effects of this stepwise approach in post-acute coronary syndrome (ACS) patients. METHODS: In a multicentre, prospective, non-randomised trial, we evaluated a three-step strategy aiming to reduce LDLC to ≤â¯1.8â¯mmol/l in post-ACS patients with prior ASCVD and/or diabetes mellitus. Steps, undertaken every 4-6 weeks, included: 1) start high-intensity statin (HIST); 2) addition of ezetimibe; 3) addition of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i). The primary outcome was the proportion of patients achieving LDL-Câ¯≤ 1.8â¯mmol/l after Steps 1 and 2 (using oral medications alone). Secondary outcomes examined the prevalence of meeting the target throughout all steps ( https://onderzoekmetmensen.nl/nl/trial/21157 ). RESULTS: Out of 999 patients, 84% (95% confidence intervals (CI): 81-86) achieved the LDLC target using only statin and/or ezetimibe. In an intention-to-treat analysis, the percentages of patients meeting the LDLC target after each step were 69% (95% CI: 67-72), 84% (95% CI: 81-86), and 87% (95% CI: 85-89), respectively. There were protocol deviations for 23, 38 and 23 patients at each respective step. CONCLUSION: Through stepwise intensification of lipid-lowering therapy, 84% of very high-risk post-ACS patients achieved an LDLC target of ≤â¯1.8â¯mmol/l with oral medications alone. Addition of PCSK9i further increased this rate to 87% (95% CI: 85-89).
RESUMO
AIMS: The European Systematic Coronary Risk Evaluation 2 (SCORE2) and SCORE2-Older Persons (OP) models are recommended to identify individuals at high 10-year risk for cardiovascular disease (CVD). Independent validation and assessment of clinical utility is needed. This study aims to assess discrimination, calibration, and clinical utility of low-risk SCORE2 and SCORE2-OP. METHODS AND RESULTS: Validation in individuals aged 40-69 years (SCORE2) and 70-79 years (SCORE2-OP) without baseline CVD or diabetes from the European Prospective Investigation of Cancer (EPIC) Norfolk prospective population study. We compared 10-year CVD risk estimates with observed outcomes (cardiovascular mortality, non-fatal myocardial infarction, and stroke). For SCORE2, 19 560 individuals (57% women) had 10-year CVD risk estimates of 3.7% [95% confidence interval (CI) 3.6-3.7] vs. observed 3.8% (95% CI 3.6-4.1) [observed (O)/expected (E) ratio 1.0 (95% CI 1.0-1.1)]. The area under the curve (AUC) was 0.75 (95% CI 0.74-0.77), with underestimation of risk in men [O/E 1.4 (95% CI 1.3-1.6)] and overestimation in women [O/E 0.7 (95% CI 0.6-0.8)]. Decision curve analysis (DCA) showed clinical benefit. Systematic Coronary Risk Evaluation 2-Older Persons in 3113 individuals (58% women) predicted 10-year CVD events in 10.2% (95% CI 10.1-10.3) vs. observed 15.3% (95% CI 14.0-16.5) [O/E ratio 1.6 (95% CI 1.5-1.7)]. The AUC was 0.63 (95% CI 0.60-0.65) with underestimation of risk across sex and risk ranges. Decision curve analysis showed limited clinical benefit. CONCLUSION: In a UK population cohort, the SCORE2 low-risk model showed fair discrimination and calibration, with clinical benefit for preventive treatment initiation decisions. In contrast, in individuals aged 70-79 years, SCORE2-OP demonstrated poor discrimination, underestimated risk in both sexes, and limited clinical utility.
To effectively prevent heart disease, it is important to identify individuals who are at a higher risk of developing it. Researchers have developed models that can estimate the likelihood of a healthy person developing heart disease within the next 10 years. This study, involving 22 673 healthy individuals in the UK, aimed to determine if these risk estimation models are accurate and can guide decisions about who should receive preventive treatment.

BACKGROUND: In patients with ischaemic heart disease (IHD) aged >â¯70 years, Dutch and European guidelines recommend different treatment targets: low-density lipoprotein cholesterol (LDL-c) <â¯2.6 versus <â¯1.4â¯mmol/l and systolic blood pressure (SBP) <â¯140 versus <â¯130â¯mmâ¯Hg, respectively. How this impacts cardiovascular event-free life expectancy has not been investigated. The study objective was to compare estimated lifelong treatment benefits of implementing Dutch and European LDLc and SBP targets. METHODS: Data from patients aged 71-80 years hospitalised for IHD in 2017-2019 were extracted from the PHARMO Database Network, which links primary and secondary healthcare settings, with follow-up until 31 December 2020. Potential benefit according to treatment strategy (in gain in event-free years) was estimated using the SMART-REACH model. RESULTS: Of the 3003 eligible patients, 1186 (39%) had missing LDLc and/or SBP measurements. Of the 1817 included patients (36% women, median age at event: 74 years (interquartile range (IQR): 72-77), 84% achieved the Dutch targets for both LDLc and SBP; for European targets, this was 23% and 61%, respectively. If Dutch targets were met for LDLc and SBP (nâ¯= 1281), the additional effect of reaching European targets was a median gain of 0.6 event-free life years (IQR: 0.3-1.0). The greatest effect could be reached in patients not reaching Dutch targets (nâ¯= 501), with a median gain of 0.6 (IQR: 0.2-1.2) and 1.7 (IQR: 1.2-2.5) event-free years with Dutch versus European targets. CONCLUSION: In patients aged >â¯70 years with IHD, implementation of European targets resulted in a greater gain of event-free years compared with Dutch targets, especially in patients with poorer risk factor control. The considerable number of patients with missing risk factor documentation suggested additional opportunities for risk reduction.
RESUMO
OBJECTIVE: Longitudinal consequences and potential interactions of COVID-19 and elite-level sports and exercise are unclear. Therefore, we determined the long-term detrimental cardiac effects of the interaction between SARS-CoV-2 infection and the highest level of sports and exercise. METHODS: This prospective controlled study included elite athletes from the Evaluation of Lifetime participation in Intensive Top-level sports and Exercise cohort. Athletes infected with SARS-CoV-2were offered structured, additional cardiovascular screenings, including cardiovascular MRI (CMR). We compared ventricular volumes and function, late gadolinium enhancement (LGE) and T1 relaxation times, between infected and non-infected elite athletes, and collected follow-up data on cardiac adverse events, ventricular arrhythmia burden and the cessation of sports careers. RESULTS: We included 259 elite athletes (mean age 26±5 years; 40% women), of whom 123 were infected (9% cardiovascular symptoms) and 136 were controls. We found no differences in function and volumetric CMR parameters. Four infected athletes (3%) demonstrated LGE (one reversible), compared with none of the controls. During the 26.7 (±5.8) months follow-up, all four athletes resumed elite-level sports, without an increase in ventricular arrhythmias or adverse cardiac remodelling. None of the infected athletes reported new cardiac symptoms or events. The majority (n=118; 96%) still participated in elite-level sports; no sports careers were terminated due to SARS-CoV-2. CONCLUSIONS: This prospective study demonstrates the safety of resuming elite-level sports after SARS-CoV-2 infection. The medium-term risks associated with SARS-CoV-2 infection and elite-level sports appear low, as the resumption of elite sports did not lead to detrimental cardiac effects or increases in clinical events, even in the four elite athletes with SARS-CoV-2 associated myocardial involvement.

Background.The hemodynamic cardiac profiler (HCP) is a new, non-invasive, operator-independent screening tool that uses six independent electrode pairs on the frontal thoracic skin, and a low-intensity, patient-safe, high-frequency applied alternating current to measure ventricular volume dynamics during the cardiac cycle for producing ventricular volume-time curves (VTCs).Objective.To validate VTCs from HCP against VTCs from MRI in healthy volunteers.Approach.Left- and right-ventricular VTCs were obtained by HCP and MRI in six healthy participants in supine position. Since HCP is not compatible with MRI, HCP measurements were performed within 20 min before and immediately after MRI, without intermittent fluid intake or release by participants. Intraclass correlation coefficients (ICCs) were calculated to validate HCP-VTC against MRI-VTC and to assess repeatability of HCP measurements before and after MRI. Bland-Altman plots were used to assess agreement between relevant HCP- and MRI-VTC-derived parameters. Precision of HCP's measurement of VTC-derived parameters was determined for each study participant by calculating the coefficients of variation and repeatability coefficients.Main results.Left- and right-ventricular VTC ICCs between HCP and MRI were >0.8 for all study participants, indicating excellent agreement between HCP-VTCs and MRI-VTCs. Mean (range) ICC of HCP right-ventricular VTC versus MRI right-ventricular VTC was 0.94 (0.88-0.99) and seemed to be slightly higher than the mean ICC of HCP left-ventricular VTC versus MRI-VTC (0.91 (0.80-0.96)). The repeatability coefficient for HCP's measurement of systolic time (tSys) was 45.0 ms at a mean value of 282.9 ± 26.3 ms. Repeatability of biventricular HCP-VTCs was excellent (ICC 0.96 (0.907-0.995)).Significance.Ventricular volume dynamics measured by HCP-VTCs show excellent agreement with VTCs measured by MRI. Since abnormal tSys is a sign of numerous cardiac diseases, the HCP may potentially be used as a diagnostic screening tool.

The recognition of myocarditis as a rare side effect of SARS-CoV-2 mRNA vaccination has sparked a global debate on vaccine safety, especially in the realm of sports. The main proposed mechanisms in the pathogenesis of COVID-19 mRNA vaccination-associated myocarditis (C-VAM) are based on the activation of the innate- and adaptive immune system against a susceptible immune-genetic background, including the recognition of mRNA as an antigen by the immune system, molecular mimicry between SARS-CoV-2 spike glycoprotein and cardiac tissue antigens and inflammatory sex-hormone signalling. The relatively younger age of the athlete population hypothetically constellates an increased risk of C-VAM. A subgroup analysis in individuals under 40 years revealed a low incidence of myocarditis following COVID-19 mRNA vaccination when compared to positive SARS-CoV-2 tests. No confirmed cases of athletes experiencing cardiac complications after mRNA vaccination have been reported. Most athletes only reported mild side effects after COVID-19 vaccination. A small but statistically significant decrease in maximal oxygen consumption in recreational athletes occurred after BNT162b2 mRNA booster vaccine administration. The clinical relevance and temporality of which remain to be determined. Many speculative social media reports attribute sudden cardiac arrest/death (SCA/D) in athletes to mRNA vaccination. Large media outlets have thoroughly debunked these claims. There is currently no evidence to support the claim that COVID-19 mRNA vaccination increases the risk of myocardial sequelae or SCA/D in athletes. However, specific vaccine regimen selection and timing may be appropriate to prevent detrimental performance effects.

BACKGROUND: Sudden cardiac death (SCD) is the leading medical cause of death in athletes. To prevent SCD, screening for high-risk cardiovascular conditions (HRCC) is recommended. Screening strategies are based on a limited number of studies and expert consensus. However, evidence and efficacy of athlete HRCC screening is unclear. OBJECTIVE: To determine methodological quality and quality of evidence of athlete screening, and screening efficacy to detect HRCC in a systematic review. METHODS: We performed a systematic search of Medline, Embase, Scopus and Cochrane Library up to June 2021. We included articles containing original data of athlete cardiovascular screening, providing details of screening strategies, test results and HRCC detection. We assessed methodological quality of the included articles by QUADAS-2, quality of evidence of athlete HRCC screening by GRADE, and athlete HRCC screening efficacy by SWiM. RESULTS: Of 2720 citations, we included 33 articles (1991-2018), comprising 82 417 athletes (26.7% elite, 73.4% competitive, 21.7% women, 75.2% aged ≤35). Methodological quality was 'very low' (33 articles), caused by absence of data blinding and inappropriate statistical analysis. Quality of evidence was 'very low' (33 articles), due to observational designs and population heterogeneity. Screening efficacy could not be reliably established. The prevalence of HRCC was 0.43% with false positive rate (FPR) 13.0%. CONCLUSIONS: Methodological quality and quality of evidence on athlete screening are suboptimal. Efficacy could not be reliably established. The prevalence of screen detected HRCC was very low and FPR high. Given the limitations of the evidence, individual recommendations need to be prudent.
RESUMO
BACKGROUND AND AIM: The efficacy of pre-COVID-19 and post-COVID-19 infection 12-lead ECGs for identifying athletes with myopericarditis has never been reported. We aimed to assess the prevalence and significance of de-novo ECG changes following COVID-19 infection. METHODS: In this multicentre observational study, between March 2020 and May 2022, we evaluated consecutive athletes with COVID-19 infection. Athletes exhibiting de-novo ECG changes underwent cardiovascular magnetic resonance (CMR) scans. One club mandated CMR scans for all players (n=30) following COVID-19 infection, despite the absence of cardiac symptoms or de-novo ECG changes. RESULTS: 511 soccer players (median age 21 years, IQR 18-26 years) were included. 17 (3%) athletes demonstrated de-novo ECG changes, which included reduction in T-wave amplitude in the inferior and lateral leads (n=5), inferior leads (n=4) and lateral leads (n=4); inferior T-wave inversion (n=7); and ST-segment depression (n=2). 15 (88%) athletes with de-novo ECG changes revealed evidence of inflammatory cardiac sequelae. All 30 athletes who underwent a mandatory CMR scan had normal findings. Athletes revealing de-novo ECG changes had a higher prevalence of cardiac symptoms (71% vs 12%, p<0.0001) and longer median symptom duration (5 days, IQR 3-10) compared with athletes without de-novo ECG changes (2 days, IQR 1-3, p<0.001). Among athletes without cardiac symptoms, the additional yield of de-novo ECG changes to detect cardiac inflammation was 20%. CONCLUSIONS: 3% of athletes demonstrated de-novo ECG changes post COVID-19 infection, of which 88% were diagnosed with cardiac inflammation. Most affected athletes exhibited cardiac symptoms; however, de-novo ECG changes contributed to a diagnosis of cardiac inflammation in 20% of athletes without cardiac symptoms.

BACKGROUND: Most patients with atherosclerotic cardiovascular disease remain at (very) high risk for recurrent events due to suboptimal risk factor control. AIMS: This study aimed to quantify the potential of maximal risk factor treatment on 10-year and lifetime risk of recurrent atherosclerotic cardiovascular events in patients 1 year after a coronary event. METHODS AND RESULTS: Pooled data from six studies are as follows: RESPONSE 1, RESPONSE 2, OPTICARE, EUROASPIRE IV, EUROASPIRE V, and HELIUS. Patients aged ≥45 years at ≥6 months after coronary event were included. The SMART-REACH score was used to estimate 10-year and lifetime risk of recurrent atherosclerotic cardiovascular events with current treatment and potential risk reduction and gains in event-free years with maximal treatment (lifestyle and pharmacological). In 3230 atherosclerotic cardiovascular disease patients (24% women), at median interquartile range (IQR) 1.1 years (1.0-1.8) after index event, 10-year risk was median (IQR) 20% (15-27%) and lifetime risk 54% (47-63%). Whereas 70% used conventional medication, 82% had ≥1 drug-modifiable risk factor not on target. Furthermore, 91% had ≥1 lifestyle-related risk factor not on target. Maximizing therapy was associated with a potential reduction of median (IQR) 10-year risk to 6% (4-8%) and of lifetime risk to 20% (15-27%) and a median (IQR) gain of 7.3 (5.4-10.4) atherosclerotic cardiovascular disease event-free years. CONCLUSIONS: Amongst patients with atherosclerotic cardiovascular disease, maximizing current, guideline-based preventive therapy has the potential to mitigate a large part of their risk of recurrent events and to add a clinically important number of event-free years to their lifetime.
Patients with heart disease are at high risk of new cardiac events. This study amongst 3230 patients who had a heart attack or received a stent or bypass surgery shows missed potential for healthy life after a heart attack. The average age of study patients was 61 years, and 24% were women. At 1 year after the cardiac event, nearly one in three (30%) continued smoking, 79% were overweight, 45% reported insufficient physical activity, 40% had high blood pressure, and 65% had a too high LDL ('bad') cholesterol. We calculated that adherence to lifestyle advice and medications could on average halve the risk for another heart attack and add over 7 healthy years of life after a heart attack. This highlights the importance of healthy lifestyle and medication adherence after a heart attack. Key finding:⢠adherence to lifestyle advice and medications could add over 7 healthy years of life after a heart attack.

Introduction: The cardiovascular benefits of physical exercise are well-known. However, vigorous exercise has also been associated with adverse cardiac effects. To improve our understanding of cardiovascular adaptation to exercise versus maladaptation and pathology, the limits of adaptation should be firmly established using state-of-the-art diagnostic modalities. We therefore initiated the Evaluation of Lifetime participation in Intensive Top-level sports and Exercise (ELITE) cohort to investigate the longitudinal (beneficial and pathological) cardiovascular effects of intensive elite sports and exercise. Methods and analysis: ELITE is a prospective, multicentre, longitudinal cohort study. Elite athletes, from the age of sixteen, are recruited in The Netherlands. The primary objective is to determine the association between elite sports and exercise-induced cardiac remodelling, cardiac pathology, and health benefits over time. Secondary objectives include determining and identifying genetic profiles of elite athletes, and how these are associated with cardiac indices. ELITE will collect data from consultations, electrocardiography, echocardiography and cardiac magnetic resonance imaging, and training- and injury data. ELITE will also collect blood for biobanking and cardiogenetics. Follow-up will take place at intervals of two to five years, and after the elite athletes' professional careers have ended. In addition, a subcohort of ELITE has been established to investigate cardiac sequelae following infections associated with myocardial involvement, including SARS-CoV-2. ELITE is a prospective observational study; therefore, analyses will be primarily explorative. Ethics and dissemination: This study has been approved by the Medical Ethics Review Board of the Amsterdam University Medical Centers (NL71682.018.19). The results of the study will be disseminated by publication in peer-reviewed journals (Netherlands Trial Register number: NL9328).
RESUMO
Conventionally, scuba diving has been discouraged for adult patients with congenital heart disease (ACHD). This restrictive sports advice is based on expert opinion in the absence of high-quality diving-specific studies. However, as survival and quality of life in congenital heart disease (CHD) patients have dramatically improved in the last decades, a critical appraisal whether such restrictive sports advice is still applicable is warranted. In this review, the cardiovascular effects of diving are described and a framework for the work-up for ACHD patients wishing to engage in scuba diving is provided. In addition, diving recommendations for specific CHD diagnostic groups are proposed.
RESUMO
(A) BACKGROUND: Home-based cardiac rehabilitation (CR) is an attractive alternative for frail older patients who are unable to participate in hospital-based CR. Yet, the feasibility of home-based CR provided by primary care physiotherapists (PTs) to these patients remains uncertain. (B) OBJECTIVE: To investigate physiotherapists' (PTs) clinical experience with a guideline-centered, home-based CR protocol for frail older patients. (C) METHODS: A qualitative study examined the home-based CR protocol of a randomized controlled trial. Observations and interviews of the CR-trained primary care PTs providing home-based CR were conducted until data saturation. Two researchers separately coded the findings according to the theoretical framework of Gurses. (D) RESULTS: The enrolled PTs (n = 8) had a median age of 45 years (IQR 27-57), and a median work experience of 20 years (IQR 5-33). Three principal themes were identified that influence protocol-adherence by PTs and the feasibility of protocol-implementation: 1) feasibility of exercise testing and the exercise program; 2) patients' motivation and PTs' motivational techniques; and 3) interdisciplinary collaboration with other healthcare providers in monitoring patients' risks. (E) CONCLUSION: Home-based CR for frail patients seems feasible for PTs. Recommendations on the optimal intensity, use of home-based exercise tests and measurement tools, and interventions to optimize self-regulation are needed to facilitate home-based CR.

An accelerated idioventricular rhythm was seen on a routine preparticipation electrocardiogram of a 19-year-old healthy and symptom-free athlete. Family history was negative for cardiac disease. Additional investigations revealed a hypertrophic cardiomyopathy, confirmed with cardiac magnetic resonance imaging and genetic analysis. Accelerated idioventricular rhythm in young athletes warrants careful clinical evaluation. (Level of Difficulty: Advanced.).
