RESUMO
BACKGROUND: In patients with newly diagnosed heart failure (HF) and left ventricular ejection fraction (LVEF) <50%, little is known whether LVEF per se or presence of coronary artery disease (CAD) provides independent prognostic information on all-cause mortality. METHODS AND RESULTS: Using the WDHR (Western Denmark Heart Registry), we identified 3620 patients with newly diagnosed HF and LVEF 10% to 49% referred for first-time coronary angiography as part of general workup of HF. Patients were stratified by LVEF (10%-35% versus 36%-49%) and presence of CAD. We estimated 10-year all-cause mortality risk and calculated hazard ratios adjusted for relevant comorbidities and risk factors (aHRs). CAD was present in 1592 (44%) patients. Lower LVEF was associated with a relative 15% increased 10-year mortality: 37% for LVEF 36% to 49% versus 42% for LVEF 10% to 35% (aHR, 1.15 [95% CI, 0.99-1.34]). This result did not change when stratified into those with CAD (52% versus 56%; aHR, 1.11 [95% CI, 0.91-1.35]) and those without CAD (27% versus 33%; aHR, 1.24 [95% CI, 0.97-1.57]). In comparison, presence and extent of CAD were associated with a relative 43% increased 10-year mortality (CAD versus no CAD, 55.0% versus 31.5%; aHR, 1.43 [95% CI, 1.25-1.64]). Compared with a matched general population, excess mortality risk was higher for patients with HF and CAD (54.7% versus 26.3%; aHR, 2.10 [95% CI, 1.85-2.39]) versus those with HF and no CAD (31.4% versus 17.2%; aHR, 1.76 [95% CI, 1.52-2.02]). CONCLUSIONS: Among newly diagnosed patients with HF and LVEF <50%, presence and extent of CAD are associated with substantial higher all-cause mortality risk than lower LVEF.

BACKGROUND: Some autoimmune diseases carry elevated risk for atherosclerotic cardiovascular disease (ASCVD), yet the underlying mechanism and the influence of traditional risk factors remain unclear. OBJECTIVES: This study sought to determine whether autoimmune diseases independently correlate with coronary atherosclerosis and ASCVD risk and whether traditional cardiovascular risk factors modulate the risk. METHODS: The study included 85,512 patients from the Western Denmark Heart Registry undergoing coronary computed tomography angiography. A diagnosis of 1 of 18 autoimmune diseases was assessed. Adjusted OR (aOR) for any plaque, any coronary artery calcification (CAC), CAC of >90th percentile, and obstructive coronary artery disease as well as adjusted HR (aHR) for ASCVD were calculated. RESULTS: During 5.3 years (Q1-Q3: 2.8-8.2 years) of follow-up, 3,832 ASCVD events occurred. A total of 4,064 patients had a diagnosis of autoimmune disease, which was associated with both presence of any plaque (aOR: 1.29; 95% CI: 1.20-1.40), any CAC (aOR: 1.28; 95% CI: 1.19-1.37), and severe CAC of >90th percentile (aOR: 1.53; 95% CI: 1.39-1.68), but not with having obstructive coronary artery disease (aOR: 1.04; 95% CI: 0.91-1.17). Patients with autoimmune diseases had a 46% higher risk (aHR: 1.46; 95% CI: 1.29-1.65) for ASCVD. Traditional cardiovascular risk factors were strongly associated with future ASCVD events, and a favorable cardiovascular risk factor profile in autoimmune patients was associated with â¼54% lower risk compared to patients with presence of risk factors (aHR: 0.46; 95% CI: 0.27-0.81). CONCLUSIONS: Autoimmune diseases were independently associated with higher burden of coronary atherosclerosis and higher risk for future ASCVD events, with risk accentuated by traditional cardiovascular risk factors. These findings suggest that autoimmune diseases increase risk through accelerated atherogenesis and that cardiovascular risk factor control is key for improving prognosis in patients with autoimmune diseases.

BACKGROUND: Low-density lipoprotein cholesterol (LDL-C) and apolipoprotein B (apoB) are highly correlated measures of atherogenic lipoproteins. OBJECTIVES: The study investigators hypothesized that excess apoB is associated with an increased risk of myocardial infarction (MI), atherosclerotic cardiovascular disease (ASCVD), and all-cause mortality. METHODS: The study included 53,484 women and 41,624 men not taking statins from the Copenhagen General Population Study. Associations of excess apoB with the risk of MI, ASCVD, and all-cause mortality were estimated by Cox proportional hazards regressions with 95% CIs. Excess apoB was defined as measured levels of apoB minus expected levels of apoB from LDL-C alone; expected levels were defined by linear regressions of LDL-C levels vs apoB levels in individuals with triglycerides ≤1 mmol/L (89 mg/dL). RESULTS: During a median follow-up of 9.6 years, 2,048 MIs, 4,282 ASCVD events, and 8,873 deaths occurred. There was a dose-dependent association between excess apoB and the risk of MI and ASCVD in both women and men, as well as an association with the risk of all-cause mortality in women. For ASCVD in women compared with those with excess apoB <11 mg/dL, the multivariable adjusted HR was 1.08 (95% CI: 0.97-1.21) for excess apoB 11 to 25 mg/dL, 1.30 (95% CI: 1.14-1.48) for 26 to 45 mg/dL, 1.34 (95% CI: 1.14-1.58) for 46 to 100 mg/dL, and 1.75 (95% CI: 1.08-2.83) for excess apoB >100 mg/dL. Corresponding HRs in men were 1.14 (95% CI: 1.02-1.26), 1.41 (95% CI: 1.26-1.57), 1.41 (95% CI: 1.25-1.60), and 1.52 (95% CI: 1.13-2.05), respectively. Results were robust across the entire LDL-C spectrum. CONCLUSIONS: Excess apoB (ie, the value of apoB above that contributed by LDL-C levels alone) is associated dose-dependently with an increased risk of MI and ASCVD in women and men. This finding demonstrates that apoB provides important predictive value beyond LDL-C across the entire LDL-C spectrum.

AIMS: Assessment of residual cardiovascular risk in statin-treated patients with atherosclerotic cardiovascular disease (ASCVD) is pivotal for optimizing secondary preventive therapies. This study investigates if non-high-density lipoprotein cholesterol (non-HDL-C) is associated with residual ASCVD risk in statin-treated ischaemic heart disease (IHD) patients with and without diabetes. METHODS AND RESULTS: Using the Western Denmark Heart Registry, we identified statin-treated patients with IHD examined by coronary angiography (CAG) from 2011 to 2020. Non-HDL-C was assessed within 1 year after CAG. Outcomes were ASCVD (myocardial infarction, ischaemic stroke, and cardiovascular death) and all-cause death. Cox regression analyses obtained hazard ratios (HRs) adjusted for age, sex, smoking, and hypertension. A total of 42 057 patients were included: 8196 patients with diabetes and 33 861 without diabetes. During the median 4.6 years of follow-up, event rates per 1000 person-years of ASCVD were 28.8 (27.1-30.5) and 17.2 (16.5-17.8) among patients with and without diabetes. In patients with diabetes, the adjusted HRs of ASCVD as compared with non-HDL-C < 25th percentile were 1.0 (0.9-1.2), 1.3 (1.1-1.6), and 1.6 (1.2-2.1) for patients in the 25th-74th, 75th-94th, and ≥95th percentiles. In patients without diabetes, the corresponding adjusted HRs were 1.1 (0.9-1.1), 1.2 (1.1-1.4), and 1.7 (1.4-2.0). Results were consistent across sex, age, clinical presentation, and low-density lipoprotein cholesterol strata. CONCLUSION: In statin-treated IHD patients with and without diabetes, non-HDL-C, especially above the 75th percentile, is associated with residual cardiovascular risk. These results have implications for secondary prevention, targeting patients who may benefit most from intensified preventive therapy.
Relevant to individuals, both with and without diabetes, who receive cholesterol-lowering therapy due to ischaemic heart disease, having a high level of non-HDL cholesterol is associated with risk of heart attack, stroke, and death.In individuals with diabetes, having a high compared to a low non-HDL cholesterol level was associated with a 3060% increased risk of heart attack, stroke, and death. For individuals without diabetes, the high non-HDL cholesterol level was linked to an increased risk by up to 70%.In clinical practice, calculation of non-HDL cholesterol, from the standard lipid profile with no inconvenience to the patient, offers a possibility to identify patients who face a high risk of heart attack, stroke, and death. Patients with high levels of non-HDL cholesterol may benefit from optimized preventive therapy.

BACKGROUND: Although a coronary artery calcium (CAC) of ≥1,000 is a subclinical atherosclerosis threshold to consider combination lipid-lowering therapy, differentiating very high from high atherosclerotic cardiovascular disease (ASCVD) risk in this patient population is not well-defined. OBJECTIVES: Among persons with a CAC of ≥1,000, the authors sought to identify risk factors equating with very high-risk ASCVD mortality rates. METHODS: The authors studied 2,246 asymptomatic patients with a CAC of ≥1,000 from the CAC Consortium without a prior ASCVD event. Cox proportional hazards regression modelling was performed for ASCVD mortality during a median follow-up of 11.3 years. Crude ASCVD mortality rates were compared with those reported for secondary prevention trial patients classified as very high risk, defined by ≥2 major ASCVD events or 1 major event and ≥2 high-risk conditions (1.4 per 100 person-years). RESULTS: The mean age was 66.6 years, 14% were female, and 10% were non-White. The median CAC score was 1,592 and 6% had severe left main (LM) CAC (vessel-specific CAC ≥300). Diabetes (HR: 2.04 [95% CI: 1.47-2.83]) and severe LM CAC (HR: 2.32 [95% CI: 1.51-3.55]) were associated with ASCVD mortality. The ASCVD mortality per 100 person-years for all patients was 0.8 (95% CI: 0.7-0.9), although higher rates were observed for diabetes (1.4 [95% CI: 0.8-1.9]), severe LM CAC (1.3 [95% CI: 0.6-2.0]), and both diabetes and severe LM CAC (7.1 [95% CI: 3.4-10.8]). CONCLUSIONS: Among asymptomatic patients with a CAC of ≥1,000 without a prior index event, diabetes, and severe LM CAC define very high risk ASCVD, identifying individuals who may benefit from more intensive prevention therapies across several domains, including low-density lipoprotein-cholesterol lowering.

AIMS: It is unclear how serial high-sensitivity troponin-I (hsTnI) concentrations affect long-term prognosis in individuals with suspected acute coronary syndrome (ACS). METHODS AND RESULTS: Subjects who underwent two hsTnI measurements (Siemens TnI Flex® Reagent) separated by 1-7â h, during a first-time hospitalization for myocardial infarction, unstable angina, observation for suspected myocardial infarction, or chest pain from 2012 through 2019, were identified through Danish national registries. Individuals were stratified per their hsTnI concentration pattern (normal, rising, persistently elevated, or falling) and the magnitude of hsTnI concentration change (<20%, >20-50%, or >50% in either direction). We calculated absolute and relative mortality risks standardized to the distributions of risk factors for the entire study population. A total of 20 609 individuals were included of whom 2.3% had died at 30 days, and an additional 4.7% had died at 365 days. The standardized risk of death was highest among persons with a persistently elevated hsTnI concentration (0-30 days: 8.0%, 31-365 days: 11.1%) and lowest among those with two normal hsTnI concentrations (0-30 days: 0.5%, 31-365 days: 2.6%). In neither case did relative hsTnI concentration changes between measurements clearly affect mortality risk. Among persons with a rising hsTnI concentration pattern, 30-day mortality was higher in subjects with a >50% rise compared with those with a less pronounced rise (2.2% vs. <0.1%). CONCLUSION: Among individuals with suspected ACS, those with a persistently elevated hsTnI concentration consistently had the highest risk of death. In subjects with two normal hsTnI concentrations, mortality was very low and not affected by the magnitude of change between measurements.
In this Danish study of >20 000 individuals with suspected heart attack, we confirmed the clinical importance of drawing two consecutive blood samples for measurement of high-sensitivity troponin-I concentrations (a marker of damage to the heart): The risk of death was highest in persons with two elevated high-sensitivity troponin-I concentrations and lowest in those with two normal concentrations.Among persons who had a first normal and a subsequently elevated high-sensitivity troponin-I concentration, a >50% relative rise was associated with significantly higher risk of death at 30 days.

BACKGROUND: Contemporary data on cardiovascular disease (CVD) risk in patients with newly diagnosed type 2 diabetes mellitus (T2DM) is needed to guide appropriate preventive management. OBJECTIVES: The authors sought to investigate sex- and age-specific 10-year CVD risk in patients with newly diagnosed T2DM compared with the general population. METHODS: A cohort study was conducted of all Danish patients with T2DM diagnosed between 2006 and 2013 (n = 142,587) and sex- and age-matched individuals from the general population (n = 388,410), all without prior atherosclerotic CVD. Ten-year CVD risk (myocardial infarction, stroke, and fatal CVD) was estimated. RESULTS: A total of 52,471 CVD events were recorded. Compared with the general population, the 10-year CVD risks were higher in patients with T2DM in both sexes and across all age groups, especially among younger individuals. For example, patients aged 40 to 49 years had the largest 10-year CVD risk difference (T2DM 6.1% vs general population 3.3%; risk difference: 2.8%, subdistribution HR: 1.91; 95% CI: 1.76-2.07). The age when a given CVD risk was reached differed substantially between the cohorts. Thus, a 10-year CVD risk of 5% was reached at age 43 in men with T2DM compared with 12 years later, at age 55, in men without T2DM. A 10-year CVD risk of 5% was reached at age 51 in women with T2DM and 10 years later, at age 61, in women without T2DM. CONCLUSIONS: Newly diagnosed T2DM increased 10-year CVD risk across both sexes and all age groups, especially among younger patients, with CVD occurring ≤12 years earlier than in general population individuals.

Icosapent ethyl (IPE) is a purified eicosapentaenoic acid-only omega-3 fatty acid that significantly reduced cardiovascular (CV) events in patients receiving statins with established cardiovascular disease (CVD) and those with diabetes and additional risk factors in the pivotal REDUCE-IT trial. Since the publication of REDUCE-IT, there has been global interest in determining IPE eligibility in different patient populations, the proportion of patients who may benefit from IPE, and cost effectiveness of IPE in primary and secondary prevention settings. The aim of this review is to summarize information from eligibility and cost effectiveness studies of IPE to date. A total of sixteen studies were reviewed, involving 2,068,111 patients in the primary or secondary prevention settings worldwide. Up to forty-five percent of patients were eligible for IPE, depending on the selection criteria used (ie, REDUCE-IT criteria, US Food and Drug Administration label, Health Canada label, practice guidelines) and the population studied. Overall, eight cost-effectiveness studies across the United States, Canada, Germany, Israel, and Australia were included in this review and findings indicated that IPE is particularly cost effective in patients with established CVD.
RESUMO
Objective: To investigate whether hs-CRP and IL-6 provide additional diagnostic value beyond that achieved by the HEART score in patients with chest pain suggestive of acute coronary syndrome (ACS) admitted to the emergency department (ED). Methods: This was a post hoc analysis using data from the RACING-MI study. Baseline data, including hs-CRP and IL-6 levels, were analyzed using the plasma from the biobank. A total of 818 patients with chest pain suggestive of ACS were included in this analysis. Of these, 98 were diagnosed with ACS (12%). Logistic regression was used to identify the independent predictors of ACS development in patients with chest pain. Results: hs-CRP levels >2 mg/L were observed in 50% of all ACS cases. IL-6 levels >1.3 pg/mL were observed in 71% of all ACS cases. hs-CRP had a sensitivity of 50% and specificity of 51% for the diagnosis of ACS, whereas IL-6 had a sensitivity of 71% and specificity of 29%. The diagnostic likelihood ratios for ACS was 1.0 for hs-CRP>2 mg/L and IL-6 > 1.3 pg/mL, respectively. Logistic regression analysis revealed that age, male gender, and ongoing smoking were associated with ACS in patients with acute chest pain. No association was found between IL-6 or hs-CRP level and ACS. This was observed for both IL-6 and hs-CRP, whether assessed on a continuous scale or using prespecified cut-off values. Conclusion: Among the 818 patients admitted to the ED with chest pain suggestive of ACS, neither hs-CRP nor IL-6 provided an independent added diagnostic value. Our results suggest that inflammatory markers have limited diagnostic value in detecting patients with ACS in the ED.
RESUMO
BACKGROUND AND AIMS: Coronary computed tomography angiography (CCTA) can guide downstream preventive treatment and improve patient prognosis, but its use in relation to education level remains unexplored. METHODS: This nationwide register-based cohort study assessed all residents in Denmark between 2008-2018 without coronary artery disease (CAD) and 50-80 years of age (n = 1 469 724). Residents were divided according to four levels of education: low, lower-mid, higher-mid, and high. Outcomes were CCTA, functional testing, invasive coronary angiography (ICA), revascularization, and major adverse cardiovascular and cerebrovascular events (MACCE). RESULTS: Individuals with the lowest education level underwent CCTA (absolute risk [AR] 3.95% individuals aged ≥ 50-59, AR 3.62% individuals aged ≥ 60-69, AR 2.19% individuals aged ≥ 70-80) less often than individuals of lower-mid (AR 4.16%, AR 3.90%, AR 2.41%), higher-mid (AR 4.38%, AR 4.30%, AR 2.45%) and highest education level (AR 3.98%, AR 4.37%, AR 2.30%). Similar differences were observed for functional testing. Conversely, use of ICA, and risks of revascularization and MACCE were more common among individuals of lowest education level. Among patients examined with CCTA (n = 50 234), patients of lowest education level less often underwent functional testing and more likely initiated preventive medication, underwent ICA, revascularization, and experienced MACCE. CONCLUSION: Despite tax-financed healthcare in Denmark, individuals of lowest education level were less likely to undergo CCTA and functional testing than persons of higher education level. ICA utilization, revascularization and MACCE risks were higher for individuals of lowest education level. Among CCTA-examined patients, patients of lowest education level were more likely to initiate preventive medication and had the highest risks of revascularization and MACCE when compared to higher education level groups. These findings suggest that the preventive potential of CCTA is underutilized in individuals of lower education level, a proxy for socioeconomic status. Socioeconomic differences in CAD assessment, care, and outcomes are likely even larger without tax-financed healthcare.
RESUMO
BACKGROUND: The representation of women in heart failure studies has been inadequate, resulting in a knowledge gap regarding the prognostic impact of coronary artery disease (CAD) on all-cause mortality in women with newly diagnosed heart failure and reduced ejection fraction (HFrEF). OBJECTIVES: This study aims to assess the prognostic impact of CAD in women with HFrEF. METHODS: Using the Western Denmark Heart Registry, the authors identified 891 women and 2,403 men referred for first-time coronary angiography because of HFrEF. The authors stratified for presence of CAD, estimated 10-year all-cause mortality, and calculated crude and adjusted HRs (aHRs) with 95% CIs. RESULTS: The 10-year mortality was 60% in women with CAD and 27% in women without CAD; for men, the corresponding numbers were 54% and 36%. When adjusted for comorbidities, women without CAD had a lower relative 10-year mortality than men without CAD (aHR: 0.73; 95% CI: 0.58-0.91), whereas women with CAD had similar relative mortality as men with CAD (aHR: 1.00; 95% CI: 0.81-1.24) (Pinteraction = 0.037). Assessed by the number of coronary vessels with significant stenosis, CAD extent was associated with mortality for both women (P < 0.01) and men (P < 0.01). However, compared to those without CAD, the aHR was higher for women with any degree of CAD (aHR ranging from 1.61 [95% CI: 1.09-2.38] for diffuse CAD to 2.01 [95% CI: 1.19-3.40] for 3-vessel disease) than for men with 3-vessel disease (aHR: 1.51; 95% CI: 1.19-1.91). CONCLUSIONS: In patients with newly diagnosed HFrEF, the presence and extent of CAD has significantly greater prognostic impact among women than among men.

BACKGROUND: Observational studies have reported that mortality rates after ST-segment elevation myocardial infarction (STEMI) have been stable since 2006 to 2010. OBJECTIVES: The aim of this study was to evaluate the temporal trends in 1-year, 30-day, and 31- to 365-day mortality after STEMI in Western Denmark where primary percutaneous coronary intervention (PCI) has been the national reperfusion strategy since 2003. METHODS: Using the Western Denmark Heart Registry, the study identified first-time PCI-treated patients undergoing primary PCI (pPCI) for STEMI from 2003 to 2018. Based on the year of pPCI, patients were divided into 4 time-interval groups and followed up for 1 year using the Danish national health registries. RESULTS: A total of 19,613 patients were included. Median age was 64 years, and 74% were male. One-year mortality decreased gradually from 10.8% in 2003-2006, 10.4% in 2007-2010, 9.1% in 2011-2014, to 7.7% in 2015-2018 (2015-2018 vs 2003-2006: adjusted HR [aHR]: 0.71; 95% CI: 0.62-0.82). The largest absolute mortality decline occurred in the 0- to 30-day period with a 2.3% reduction (aHR: 0.69; 95% CI: 0.59-0.82), and to a lesser extent in the 31- to 365-day period (risk reduction: 1.0%; aHR: 0.71; 95% CI: 0.56-0.90). CONCLUSIONS: In a high-income European country with a fully implemented pPCI strategy, 1-year mortality in pPCI-treated patients with STEMI decreased substantially between 2003 and 2018. Approximately three-quarters of the absolute mortality reduction occurred within the first 30 days after pPCI. These results indicate that optimization of early management of pPCI-treated patients with STEMI offers great opportunities for improving overall survival in contemporary clinical practice.

BACKGROUND: Elevated triglyceride levels are a clinically useful marker of remnant cholesterol. It is unknown whether triglycerides are associated with residual cardiovascular risk in CVD-naïve patients with newly diagnosed type 2 diabetes mellitus (T2DM), who are already on statin therapy. We aimed to assess the association between triglyceride levels and risk of major cardiovascular events (MACE) in statin-treated patients with newly diagnosed T2DM managed in routine clinical care. METHODS: This cohort study included newly diagnosed T2DM patients without a previous diagnosis of cardiovascular disease in Northern Denmark during 2005-2017. Individual triglyceride levels while on statin treatment were assessed within 1 year after T2DM diagnosis. The primary outcome was a composite of myocardial infarction, ischemic stroke, or cardiac death (MACE). Patients were followed from one year after T2DM diagnosis until 30 April 2021, MACE, emigration, or death. We used Cox regression to compute hazard ratios (HRs) controlling for confounding factors. RESULTS: Among 27,080 statin-treated patients with T2DM (median age 63 years; 53% males), triglyceride levels were < 1.0 mmol/L in 17%, 1.0-1.9 mmol/L in 52%, 2.0-2.9 mmol/L in 20%, and ≥ 3.0 mmol/L in 11%. During follow-up, 1,957 incident MACE events occurred (11.0 per 1000 person-years). Compared with triglyceride levels < 1.0 mmol/L, confounder-adjusted HRs for incident MACE were 1.14 (95% CI 1.00-1.29) for levels between 1.0 and 1.9 mmol/L, 1.30 (95% CI 1.12-1.51) for levels between 2.0 and 2.9 mmol/L, and 1.44 (95% CI 1.20-1.73) for levels ≥ 3.0 mmol/L. This association was primarily driven by higher rates of myocardial infarction and cardiac death and attenuated only slightly after additional adjustment for LDL cholesterol. Spline analyses confirmed a linearly increasing risk of MACE with higher triglyceride levels. Stratified analyses showed that the associations between triglyceride levels and MACE were stronger among women. CONCLUSIONS: In statin-treated patients with newly diagnosed T2DM, triglyceride levels are associated with MACE already from 1.0 mmol/L. This suggests that high triglyceride levels are a predictor of residual cardiovascular risk in early T2DM and could be used to guide allocation of additional lipid-lowering therapies for CVD prevention.

Introduction: The ESC recently classified European countries into 4 cardiovascular risk regions. However, whether Europeans from higher-risk countries living in lower-risk regions may benefit from intensive cardiovascular prevention efforts is unknown. We described the burden of risk factors and cardiovascular disease (CVD) among European-born immigrants living in Catalonia, a low-risk region. Material and methods: A retrospective cohort study of 5.6 million adults of European origin living in Catalonia in 2019, including 282,789 European-born immigrants, was performed. We used the regionwide healthcare database and classified participants into 5 groups: low-, moderate-, high-, and very high-risk, and local-born. Age-standardized prevalence was estimated as of December 31st, 2019 and incidence was computed during 2019 among at-risk individuals. Results: The very high-risk group was the largest immigrant group (N = 136,910; 48.4%), while the high-risk group was the smallest (N = 15,739; 5.6%). These two had the highest burden of coronary heart disease across all groups evaluated, in both men and women. The very high-risk group also had the highest prevalence of hypertension and obesity at young-to-middle age, and the burden of risk factors newly diagnosed during 2019 was highest in high- and very high-risk participants. The mean age at first diagnosis of risk factors and CVD was lower in these groups. Conclusions: In Catalonia, residents born in high- and very-high-risk European countries are at increased risk of coronary heart disease and newly diagnosed risk factors. Low-risk European countries may consider tailored prevention efforts, early screening of risk factors, and adequate healthcare resource planning to better address the health needs of men and women from higher-risk countries.
RESUMO
PURPOSE OF REVIEW: To provide a summary of recent literature on coronary artery calcium testing (CAC) for risk stratification in young adults <45âyears old. RECENT FINDINGS: One of every ten young adults in the general population, and one out of every three young adults with traditional atherosclerotic cardiovascular disease (ASCVD) risk factors, have CAC. While the definition of premature CAC has yet to be formally defined in guidelines, it has become increasingly clear that any prevalent CAC among adults <45âyears old should be considered premature. Traditional risk factors are strong predictors of CAC in young adults; however, this association has been found to wane over the life course which suggests that the onset and severity of risk factors for calcific atherosclerosis varies as individuals age. Though CAC is a robust predictor of both ASCVD and cancer-related mortality in old age, CAC in young adults confers a stepwise higher risk uniquely for incident ASCVD mortality, and not for non-ASCVD causes. New tools are available to assist in interpretation of CAC in the young, and for estimating the ideal age to initiate CAC scoring. SUMMARY: The identification of premature CAC is important because it suggests that calcific plaque can be detected with modern imaging earlier in the natural history than previously thought. Taken together, these findings underline a utility of selective use of CAC scoring on non-contrast computed tomography among at-risk young adults to facilitate timely lifestyle modification and pharmacotherapies for the prevention of later life ASCVD.

BACKGROUND: Low-density lipoprotein cholesterol (LDL-C) is an important causal risk factor for atherosclerotic cardiovascular disease (ASCVD). However, a sizable proportion of middle-aged individuals with elevated LDL-C level have not developed coronary atherosclerosis as assessed by coronary artery calcification (CAC). Whether presence of CAC modifies the association of LDL-C with ASCVD risk is unknown. We evaluated the association of LDL-C with future ASCVD events in patients with and without CAC. METHODS: The study included 23 132 consecutive symptomatic patients evaluated for coronary artery disease using coronary computed tomography angiography (CTA) from the Western Denmark Heart Registry, a seminational, multicenter-based registry with longitudinal registration of patient and procedure data. We assessed the association of LDL-C level obtained before CTA with ASCVD (myocardial infarction and ischemic stroke) events occurring during follow-up stratified by CAC>0 versus CAC=0 using Cox regression models adjusted for baseline characteristics. Outcomes were identified through linkage among national registries covering all hospitals in Denmark. We replicated our results in the National Heart, Lung, and Blood Institute-funded Multi-Ethnic Study of Atherosclerosis. RESULTS: During a median follow-up of 4.3 years, 552 patients experienced a first ASCVD event. In the overall population, LDL-C (per 38.7 mg/dL increase) was associated with ASCVD events occurring during follow-up (adjusted hazard ratio [aHR], 1.14 [95% CI, 1.04-1.24]). When stratified by the presence or absence of baseline CAC, LDL-C was only associated with ASCVD in the 10 792/23 132 patients (47%) with CAC>0 (aHR, 1.18 [95% CI, 1.06-1.31]); no association was observed among the 12 340/23 132 patients (53%) with CAC=0 (aHR, 1.02 [95% CI, 0.87-1.18]). Similarly, a very high LDL-C level (>193 mg/dL) versus LDL-C <116 mg/dL was associated with ASCVD in patients with CAC>0 (aHR, 2.42 [95% CI, 1.59-3.67]) but not in those without CAC (aHR, 0.92 [0.48-1.79]). In patients with CAC=0, diabetes, current smoking, and low high-density lipoprotein cholesterol levels were associated with future ASCVD events. The principal findings were replicated in the Multi-Ethnic Study of Atherosclerosis. CONCLUSIONS: LDL-C appears to be almost exclusively associated with ASCVD events over ≈5 years of follow-up in middle-aged individuals with versus without evidence of coronary atherosclerosis. This information is valuable for individualized risk assessment among middle-aged people with or without coronary atherosclerosis.

AIMS: Beyond 1 year after percutaneous coronary intervention (PCI), guidelines recommend anticoagulant monotherapy in patients with atrial fibrillation (AF) rather than dual therapy with an anticoagulant and an antiplatelet drug. The risks and benefits of this strategy, however, remain uncertain. We examined hospitalization for bleeding and ischaemic risk beyond 1 year after PCI in patients with AF treated with monotherapy vs. dual therapy. Furthermore, among patients treated with monotherapy, we compared direct oral anticoagulant (DOAC) therapy and vitamin K antagonist (VKA) therapy. METHODS AND RESULTS: We included all patients with AF undergoing first-time PCI between 2003 and 2017 from the Western Denmark Heart Registry and followed them for up to 4 years. Follow-up started 15 months after PCI to enable assessment of medical treatment after 12 months. Using a Cox regression model, we computed weighted hazard ratios (HRw) of hospitalization for bleeding and major adverse cardiac events (MACEs). Analyses comparing monotherapy vs. dual therapy included 3331 patients, and analyses comparing DOAC vs. VKA monotherapy included 1275 patients. Risks of hospitalization for bleeding [HRw 0.90, 95% confidence interval (CI) 0.75-1.09] and MACE (HRw 1.04, 95% CI 0.90-1.19) were similar with monotherapy and dual therapy. Similarly, risks of hospitalization for bleeding (HRw 1.27, 95% CI 0.84-1.92) and MACE (HRw 1.15, 95% CI 0.87-1.50) were equal with DOAC and VKA monotherapy. CONCLUSION: Our results support long-term OAC monotherapy beyond 1 year after PCI in patients with atrial fibrillation and suggest that DOAC monotherapy is as safe and effective as VKA monotherapy.

BACKGROUND: Long-term prognostic implications of serial high-sensitivity troponin concentrations in subjects with suspected acute coronary syndrome are unknown. METHODS AND RESULTS: Individuals with a first diagnosis of myocardial infarction, unstable angina, observation for suspected myocardial infarction, or chest pain from 2012 through 2019 who underwent two high-sensitivity troponin-T (hsTnT) measurements 1-7 h apart were identified through Danish national registries. Absolute and relative risks for death at days 0-30 and 31-365, stratified for whether subjects had normal or elevated hsTnT concentrations, and whether these concentrations changed by <20%, > 20 to 50%, or >50% in either direction from first to second measurement, were calculated through multivariable logistic regression with average treatment effect modeling. Of the 28 902 individuals included, 2.8% had died at 30 days, whereas 4.9% of those who had survived the first 30 days died between days 31-365. The standardized risk of death was highest among subjects with two elevated hsTnT concentrations (0-30 days: 4.3%, 31-365 days: 7.2%). In this group, mortality was significantly higher in those with a > 20 to 50% or >50% rise from first to second measurement, though only at 30 days. The risk of death was very low in subjects with two normal hsTnT concentrations (0-30 days: 0.1%, 31-365 days: 0.9%) and did not depend on relative or absolute changes between measurements. CONCLUSIONS: Individuals with suspected acute coronary syndrome and two consecutively elevated hsTnT concentrations consistently had the highest risk of death. Mortality was very low in subjects with two normal hsTnT concentrations, irrespective of changes between measurements.
