- BACKGROUND: Atrial fibrillation (AF) affects about 3.2% of the adult population in the western world and incurs an annual stroke risk of 4.5%. The use of oral anticoagulant (OAC) drugs significantly reduces this risk. OAC drugs seem to be under-utilized, but little is known about why their use is restrained in routine clinical management. The aim of this study was to assess this issue and, from these data, to estimate the proportion of patients with AF in a general population who were eligible for treatment with OAC drugs.DESIGN: Retrospective study of medical records.METHODS: The study included all identified patients with AF in a well-defined catchment area of 65,532 people, among whom 1616 (3.2%) had documented AF. Of the patients with AF, 588 (36%) were originally reported not to be receiving OAC drugs. The patient-responsible physicians (n = 24) were requested to complete a standardized questionnaire to assess the reason for restraining the use of OAC drugs for each individual patient.RESULTS: Of the 588 patients originally reported not to be receiving OAC drugs, eight were shown to be using OAC drugs and seven were lost to follow up. Thus the reason for restraining OAC drugs was finally assessed in 573 patients. The primary reasons were: lack of indication, 26%; declined general condition, 14%; a history of bleeding, 12%; assumed poor compliance, 11%; repeated falls, 6%; and reason unknown, 9%.CONCLUSIONS: This is, to our knowledge, the first study to assess the reasons for restraining the use of OAC drugs in a geographically well-defined population including all hospital-based and non-hospital-based healthcare. Applying CHA2DS2-VASc and new strategies for OAC drugs to our study data indicated that between 72 and 88% of all patients with AF are eligible for treatment with OAC drugs.

- AimsSubclinical carotid atherosclerosis adds predictive value to traditional risk factors for cardiovascular diseases (CVDs). Systematic Coronary Risk Assessment 2 (SCORE2), an algorithm composed of traditional risk factors, is a state-of-the-art to estimate the 10-year risk of first-onset CVDs. We aim to investigate whether and how subclinical carotid atherosclerosis affects the performance of SCORE2.Methods and resultsCarotid plaque presence and intima media thickness (IMT) were measured with ultrasound. The SCORE2 was calculated in 4588 non-diabetic participants aged 46–68 years. The incremental value for predicting CVD events of adding carotid plaque or IMT to SCORE2 was evaluated using C-statistics, continuous net reclassification improvement (NRI), and integrated discrimination improvement (IDI). The predicted 10-year CVD risk by SCORE2 and the observed event rate were compared between participants with and without carotid plaque. Adding plaque or IMT to SCORE2 significantly improved performance for predicting CVDs. The improvements in C-statistics, IDI, and NRI of adding plaque to SCORE2 for events occurring during the first 10 years were 2.20%, 0.70%, and 46.1%, respectively (all P < 0.0001). The SCORE2 over-predicted the 10-year CVD risk in those without carotid plaque (3.93% observed vs. 5.89% predicted, P < 0.0001) while under-predicted the risk in those with carotid plaque (9.69% observed vs. 8.12% predicted, P = 0.043).ConclusionCarotid ultrasound adds predictive performance to SCORE2 for assessment of CVD risk. Using SCORE2 without considering carotid atherosclerosis could under- or over-estimate the risk.

- Background The increasing prevalence of atrial fibrillation and novel therapeutic tools to prevent cardioembolic stroke has increased the need for risk markers. Objectives This study explored the relationship between the midregional sequence of pro-atrial natriuretic peptide (MR-proANP) levels with the risk of atrial fibrillation and stroke, and whether measurement of MR-proANP improves the prediction of these outcomes. Methods MR-proANP was measured in fasting blood samples of 5130 subjects (69% men, mean age 69.2 ± 6.2 years) without a history of atrial fibrillation or stroke from the general population. The incidence of atrial fibrillation and stroke was monitored over a median follow-up of 5.6 years. C-statistics and net reclassification improvement was used to assess the predictive ability of MR-proANP in addition to conventional risk factors. Results Log-normalized MR-proANP was significantly associated with the incidence of atrial fibrillation (n = 362; hazard ratio (HR); 95% confidence interval (CI) per 1 standard deviation (SD) 2.05, 1.86-2.27) and stroke from all causes (n = 195; HR 1.30; 95% CI 1.12-1.50). The HR for stroke events related to atrial fibrillation was 1.79 (95% CI 1.25-2.58) per 1 SD. MR-proANP significantly improved the prediction of atrial fibrillation when added to a risk score of conventional risk factors (C statistic 0.69 vs. 0.75), mainly by down-classifying subjects who did not develop atrial fibrillation. A smaller improvement in predictive ability was observed for stroke (C statistic 0.66 vs. 0.68). Conclusion High plasma levels of MR-proANP are associated with the incidence of atrial fibrillation and stroke in the middle-aged and elderly population. MR-proANP may be useful to identify individuals with an increased risk of atrial fibrillation.

- Background Athletes competing in athletics (track and field) at international level may be participating with underlying undiagnosed life-threatening cardiovascular conditions. Our objective was to analyse variations in pre-participation cardiac evaluation prevalence among athletes participating in two International Association of Athletics Federations (IAAF) World Athletics Championships, with regard to the human developmental level and global region of their home countries, as well as athletes’ age category, gender, event group and medical insurance type.Design Cross-sectional web-based survey.MethodsA total of 1785 athletes competing in the IAAF World Under 18 Championships Nairobi 2017 and World Championships London 2017 were invited to complete a pre-participation health questionnaire investigating the experience of a pre-participation cardiac examination.Results A total of 704 (39%) of the athletes participated. Among these, 59% (60% of women; 58% of men) reported that they had been provided at least one type of pre-participation cardiac evaluation. Athletes from very high income countries, Europe and Asia, showed a higher prevalence of at least one pre-participation cardiac evaluation.Conclusions The prevalence of pre-participation cardiac evaluation in low to middle income countries, and the African continent in particular, needs urgent attention. Furthermore, increases in evaluation prevalence should be accompanied by the development of cost-effective methods that can be adopted in all global regions.

- AIMS: Participation in exercise-based cardiac rehabilitation (exCR) increases aerobic capacity and improves outcomes in patients following myocardial infarction (MI) and is therefore universally recommended. While meta-analyses consistently report that participation in exCR reduces cardiovascular mortality, there are conflicting results regarding effects on total mortality. Presently, many eligible patients do not receive exCR in clinical practice. We aimed to investigate the relation between participation in exCR post-MI and total mortality in men and women in a nationwide real-world cohort from the SWEDEHEART registry.DESIGN: Longitudinal, observational cohort study.METHODS AND RESULTS: In total, 20 895 patients from the SWEDEHEART registry were included. Mortality data were obtained from the Swedish National Population Registry. During a mean of 4.55 (±2.33) years of follow-up, 1000 patients died. Using Cox regression for proportional odds and taking a wide range of potential confounders into consideration, participation in exCR was related to significantly lower total mortality [hazard ratio (HR) 0.72, 95% confidence interval 0.62-0.83]. Excluding patients with shorter follow-up than 2 years did not alter the results. Exercise-based CR participation was related to lowered total mortality in most of the investigated subgroups. The risk reduction was more pronounced in women than in men (HR 0.54 vs. 0.81, respectively).CONCLUSION: Participation in exCR was associated with reduced total mortality, and more pronounced in women, compared with men. Our results further support the recommendations to participate in exCR, and hence we argue that exCR should be a mandatory part of comprehensive CR programmes, offered to all patients post-MI.

- AIMS: This study aimed to evaluate the association between physical activity and the incidence of coronary heart disease (CHD) in individuals with and without CHD risk factors.METHODS AND RESULTS: EPIC-CVD is a case-cohort study of 29 333 participants that included 13 582 incident CHD cases and a randomly selected sub-cohort nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Self-reported physical activity was summarized using the Cambridge physical activity index (inactive, moderately inactive, moderately active, and active). Participants were categorized into sub-groups based on the presence or the absence of the following risk factors: obesity (body mass index ≥30 kg/m2), hypercholesterolaemia (total cholesterol ≥6.2 mmol/L), history of diabetes, hypertension (self-reported or ≥140/90 mmHg), and current smoking. Prentice-weighted Cox regression was used to assess the association between physical activity and incident CHD events (non-fatal and fatal).Compared to inactive participants without the respective CHD risk factor (referent), excess CHD risk was highest in physically inactive and lowest in moderately active participants with CHD risk factors. Corresponding excess CHD risk estimates amongst those with obesity were 47% [95% confidence interval (CI) 32-64%] and 21% (95%CI 2-44%), with hypercholesterolaemia were 80% (95%CI 55-108%) and 48% (95%CI 22-81%), with hypertension were 80% (95%CI 65-96%) and 49% (95%CI 28-74%), with diabetes were 142% (95%CI 63-260%), and 100% (95%CI 32-204%), and amongst smokers were 152% (95%CI 122-186%) and 109% (95%CI 74-150%).CONCLUSIONS: In people with CHD risk factors, moderate physical activity, equivalent to 40 mins of walking per day, attenuates but does not completely offset CHD risk.

- Background The ankle brachial index (ABI) is related to risk of cardiovascular events independent of the Framingham risk score (FRS). The aim of this study was to develop and evaluate a risk model for cardiovascular events incorporating the ABI and FRS. Design An analysis of participant data from 18 cohorts in which 24,375 men and 20,377 women free of coronary heart disease had ABI measured and were followed up for events. Methods Subjects were divided into a development and internal validation dataset and an external validation dataset. Two models, comprising FRS and FRS + ABI, were fitted for the primary outcome of major coronary events. Results In predicting events in the external validation dataset, C-index for the FRS was 0.672 (95% CI 0.599 to 0.737) in men and 0.578 (95% CI 0.492 to 0.661) in women. The FRS + ABI led to a small increase in C-index in men to 0.685 (95% CI 0.612 to 0.749) and large increase in women to 0.690 (95% CI 0.605 to 0.764) with net reclassification improvement (NRI) of 4.3% (95% CI 0.0 to 7.6%, p = 0.050) and 9.6% (95% CI 6.1 to 16.4%, p < 0.001), respectively. Restricting the FRS + ABI model to those with FRS intermediate 10-year risk of 10 to 19% resulted in higher NRI of 15.9% (95% CI 6.1 to 20.6%, p < 0.001) in men and 23.3% (95% CI 13.8 to 62.5%, p = 0.002) in women. However, incorporating ABI in an improved newly fitted risk factor model had a nonsignificant effect: NRI 2.0% (95% CI 2.3 to 4.2%, p = 0.567) in men and 1.1% (95% CI 1.9 to 4.0%, p = 0.483) in women. Conclusions An ABI risk model may improve prediction especially in individuals at intermediate risk and when performance of the base risk factor model is modest.

- Aims Our objective was to assess changes in the birth prevalence of CHD over a half-century in a high-resource, nationwide setting, as well as changes in the prevalence of cardiac interventions in this population. Methods and results The Swedish National Patient and Cause of Death registers were linked to estimate the annual rates of CHD and cardiac interventions among live-born infants from 1970 to 2017. Additionally, separate estimates were obtained by lesion complexity, from mild to the most complex forms of CHD. Overall, the numbers of live-born infants with a CHD identified varied from 624 to 2459 annual cases, with rates increasing steadily from 5.7 to an average of 20 per 1000 live births at the end of the study period, and with a more pronounced increase from 1996 to 2005. The largest increase over time was observed for mild CHD lesions. Overall, the proportion of cardiac interventions among patients with CHD declined from 40.7% in 1970 to below 15.0% after 2014. However, in the most complex CHD lesion groups, overall cardiac interventions increased from 57.1 to 76.8% in patients with conotruncal defects and from 32.8 to 39.5% in those with severe non-conotruncal defects. Conclusion The live-birth prevalence of CHD in Sweden more than tripled during the past half-century, most likely resulting from more accurate diagnostic capabilities. The largest increase over time was observed among patients with simple defects. During the same period, overall cardiac interventions decreased whereas interventions for the most complex CHD groups increased.

- Background: Guidelines recommend considering workload in interpretation of the systolic blood pressure (SBP) response to exercise, but reference values are lacking. Design: This was a retrospective, consecutive cohort study. Methods: From 12,976 subjects aged 18–85 years who performed a bicycle ergometer exercise test at one centre in Sweden during the years 2005–2016, we excluded those with prevalent cardiovascular disease, comorbidities, cardiac risk factors or medications. We extracted SBP, heart rate and workload (watt) from ≥ 3 time points from each test. The SBP/watt-slope and the SBP/watt-ratio at peak exercise were calculated. Age- and sex-specific mean values, standard deviations and 90th and 95th percentiles were determined. Reference equations for workload-indexed and peak SBP were derived using multiple linear regression analysis, including sex, age, workload, SBP at rest and anthropometric variables as predictors. Results: A final sample of 3839 healthy subjects (n = 1620 female) were included. While females had lower mean peak SBP than males (188 ± 24 vs 202 ± 22 mmHg, p < 0.001), workload-indexed SBP measures were markedly higher in females; SBP/watt-slope: 0.52 ± 0.21 versus 0.41 ± 0.15 mmHg/watt (p < 0.001); peak SBP/watt-ratio: 1.35 ± 0.34 versus 0.90 ± 0.21 mmHg/watt (p < 0.001). Age, sex, exercise capacity, resting SBP and height were significant predictors of the workload-indexed SBP parameters and were included in the reference equations. Conclusions: These novel reference values can aid clinicians and exercise physiologists in interpreting the SBP response to exercise and may provide a basis for future research on the prognostic impact of exercise SBP. In females, a markedly higher SBP in relation to workload could imply a greater peripheral vascular resistance during exercise than in males.
