  Background The life-long exposure of the left heart chambers to systemic blood pressures may be important to changes in left atrial (LA) function with age, but long-term follow-up studies are scarce. We aimed to assess the impact of blood pressure in mid-life on LA function assessed by echocardiographic reservoir (LASr) and contractile (LASct) strain two decades later, in men and women. Methods Echocardiography was performed at ages 62–65 in 3706 participants born in 1950 of the prospective observational Akershus Cardiac Examination (ACE) 1950 Study. Data was linked with blood pressure measurements from the Age 40 Programme, a national health survey performed when the participants were 40–43 years of age. Participants were categorised into three groups representing normal blood pressure, elevated blood pressure and hypertension, based on measurements at ages 40–43. Linear regression models were used to assess associations between blood pressure and echocardiographic LA strain analysis. Results A total of 2399 participants (51.6% women) had available LA strain analysis from the ACE 1950 Study (mean age 63.9±0.6 years) and blood pressure data from the Age 40 Programme (mean age 40.1±0.3 years). At ages 62–65, mean LASr was 35.1±9.2% and LASct was 17.7±5.6%. Adjusted regression models showed a significant association between blood pressure category increase at ages 40–43 and LASct (adjusted β 1.03% (95% CI 0.37% to 1.69%), p=0.002) at ages 62–65, but not with LASr. In women, no associations were evident between blood pressure at ages 40–43 and LA strain two decades later. Conclusions Increased blood pressure in the early 40s was associated with higher LA contractile strain two decades later in men, but not in women.

  Background We investigated the impact of left atrial appendage (LAA) function by LAA strain, LAA morphology and subclinical atrial fibrillation (AF) on LAA thrombus presence and thromboembolic risk conditions (TRC) in patients with cryptogenic stroke and transient ischaemic attack (TIA). Methods 185 patients (mean age 68±13 years, 33% female) were included in this prospective cohort study and underwent clinical evaluation, comprehensive transthoracic and transoesophageal echocardiography shortly after index event. LAA function and morphology were evaluated by monoplane/multiplane/speckle tracking strain and three-dimensional echocardiography. Combination of LAA thrombus and/or spontaneous echo contrast (SEC) was defined as TRC. An insertable cardiac monitor was implanted in all patients to detect subclinical AF. Results LAA function by novel LAA strain and LAA chicken wing were independent predictors of LAA thrombus (OR 0.9 (95% CI 0.8 to 0.95), p<0.01 and OR 2.5 (95% CI 1.1 to 5.8), p=0.04, respectively). LAA chicken wing and multilobate LAA were independent predictors of TRC (OR 2.3 (95% CI 1.2 to 4.5), p=0.01 and OR 2.2 (95% CI 1.2 to 4.2), p=0.02, respectively). LAA morphology was characterised as chicken wing in 79 (43%), windsock in 64 (34%), cactus in 35 (19%), cauliflower in 7 (4%) and multilobate LAA in 115 (62%) patients. LAA thrombus was found in 29 (16%), TRC in 123 (67%) and subclinical AF in 60 (32%) patients. Duration of subclinical AF >6 hours was associated with SEC and recurrent stroke and TIA. Conclusion LAA function by novel LAA strain and LAA structure are independently associated with LAA thrombus and TRC in patients with cryptogenic stroke and TIA. Trial registration number NCT02725944.

  Purpose To assess left atrial (LA) function in individuals with known paroxysmal atrial fibrillation (AF) compared with healthy and nonhealthy individuals without atrial fibrillation. Methods The Akershus Cardiac Examination 1950 Study included 3,706 individuals all born in 1950. LA strain assessment of reservoir (LASr), conduit (LAScd) and contractile (LASct) functions were performed in all participants by investigators blinded to clinical data. Participants with cardiovascular disease, obesity, diabetes, pulmonary or renal disease were defined as nonhealthy, and those without as healthy. Patients with paroxysmal AF were identified through medical history and ECG documentation. Results LA strain assessment was feasible in 3,229 (87%) of the participants (50% women). The healthy group (n = 758) had significantly higher LASr and LAScd than the nonhealthy (n = 2,376), but LASct was similar between the groups. Participants with paroxysmal AF had significantly lower values of all strain parameters than the other groups. Multivariable logistic regression showed a significantly reduced probability of having AF per standard deviation increase in LASr and LASct. A nonlinear restricted cubic spline model fitted better with the association of LASr with paroxysmal AF than the linear model, and LA strain values below the population mean associated with an increased probability of having AF, but for values above the population mean no such association was present. Conclusion Compared to participants without AF, those with known paroxysmal AF had significantly lower values of all LA strain parameters during sinus rhythm. Lower values of LA strain were associated with a significantly increased probability of having AF.

  Abstract Aims Left atrial (LA) strain is promising in prediction of clinical atrial fibrillation (AF) in stroke patients. However, prediction of subclinical AF is critical in patients with embolic strokes of undetermined source (ESUS). The aim of this prospective study was to investigate novel LA and left atrial appendage (LAA) strain markers in prediction of subclinical AF in ESUS patients. Methods and results A total of 185 patients with ESUS, mean age 68 ± 13years, 33% female, without diagnosed AF, were included. LAA and LA function by conventional echocardiographic parameters and reservoir strain (Sr), conduit strain (Scd), contraction strain (Sct), and mechanical dispersion (MD) of Sr were assessed with transoesophageal and transthoracic echocardiography. Subclinical AF was detected by insertable cardiac monitors during follow-up. LAA strain was impaired in 60 (32%) patients with subclinical AF compared to those with sinus rhythm: LAA-Sr, 19.2 ± 4.5% vs. 25.6 ± 6.5% (P &amp;lt; 0.001); LAA-Scd, −11.0 ± 3.1% vs. −14.4 ± 4.5% (P &amp;lt; 0.001); and LAA-Sct, −7.9 ± 4.0% vs. −11.2 ± 4% (P &amp;lt; 0.001), respectively, while LAA-MD was increased, 34 ± 24 ms vs. 26 ± 20 ms (P = 0.02). However, there was no significant difference in phasic LA strain or LA-MD. By ROC analyses, LAA-Sr was highly significant in prediction of subclinical AF and showed the best AUC of 0.80 (95% CI 0.73–0.87) with a sensitivity of 80% and a specificity of 73% (P &amp;lt; 0.001). LAA-Sr and LAA-MD were both independent and incremental markers of subclinical AF in ESUS patients. Conclusion LAA function by strain and mechanical dispersion predicted subclinical AF in ESUS patients. These novel echocardiographic markers may improve risk stratification in ESUS patients.

  Background Echocardiographic measures of left atrial volumes are powerful predictors of cardiovascular events and important for assessing diastolic dysfunction. Despite this, there is limited knowledge of factors influencing left atrial remodeling. In particular, the impact of blood pressure in those in their early 40s on left atrial volumes later in life has not been sufficiently elucidated. Methods and Results We linked data from individuals born in 1950 who participated in the Age 40 Program, and the ACE (Akershus Cardiac Examination) 1950 Study. We divided the study population into quartiles of systolic blood pressure in their early 40s and assessed the proportion of individuals with an enlarged left atrium in their mid‐60s. The associations between blood pressure and left atrial volumes were assessed in linear regression analyses. Of the 2591 individuals included in this study, 1302 (50.3%) were women, and the mean age in the Age 40 Program was 40.1±0.3 years. Systolic blood pressure was 128.1±13.6 mm Hg and diastolic blood pressure was 78.3±9.5 mm Hg. Mean age in the ACE 1950 Study was 64.0±0.6 years. The proportion of individuals with an enlarged left atrium increased across the quartiles of systolic blood pressure (P=0.001). Systolic blood pressure was independently associated with left atrial volumes; the end‐systolic volume was 0.09 mL (95% CI, 0.04–0.14 mL) larger per 1‐mm Hg higher systolic blood pressure. Conclusions Our findings suggest that increased blood pressure in those in their early 40s is relevant for left atrial remodeling later in life.

  Background A high intake of linoleic acid (LA), the major dietary polyunsaturated fatty acid (PUFA), has previously been associated with reduced cardiovascular (CV) morbidity and mortality in observational studies. However, recent secondary analyses from clinical trials of LA-rich diet suggest harmful effects of LA on CV health. Methods A total of 3706 participants, all born in 1950, were included in this cross-sectional study. We investigated associations between plasma phospholipid levels of LA and CV risk factors in a Norwegian general population, characterized by a relative low LA and high marine n-3 PUFA intake. The main statistical approach was multivariable linear regression. Results Plasma phospholipid LA levels ranged from 11.4 to 32.0 wt%, with a median level of 20.8 wt% (interquartile range 16.8–24.8 wt%). High plasma LA levels were associated with lower serum low-density lipoprotein cholesterol levels (standardized regression coefficient [Std. β-coeff.] −0.04, p = 0.02), serum triglycerides (Std. β-coeff. −0.10, p < 0.001), fasting plasma glucose (Std. β-coeff. −0.10, p < 0.001), body mass index (Std. β-coeff. −0.13, p < 0.001), systolic and diastolic blood pressure (Std. β-coeff. −0.04, p = 0.03 and Std. β-coeff. −0.02, p = 0.02, respectively) and estimated glomerular filtration rate (Std. β-coeff. −0.09, p < 0.001). We found no association between plasma LA levels and high-density lipoprotein cholesterol levels, glycated hemoglobin, carotid intima-media thickness, or C-reactive protein. Conclusion High plasma LA levels were favorably associated with several CV risk factors in this study of a Norwegian general population.

  Intake of industrially produced trans fatty acids (iTFAs) has previously been associated with dyslipidemia, insulin resistance, hypertension and inflammation, as well as increased cardiovascular (CV) morbidity and mortality. iTFA intake declined in Norway after the introduction of legislative bans against iTFA consumption. However, the relationship between the current iTFA intake and CV health is unclear. The aim of the present study was to investigate the association between current iTFA intake, reflected by plasma iTFA levels, and established CV risk factors. We also examined the associations between plasma ruminant TFA levels and CV risk factors. In this cross-sectional study, we included 3706 participants from a Norwegian general population, born in 1950 and residing in Akershus County, Norway. The statistical method was multivariable linear regression. Plasma iTFA levels were inversely associated with serum triglycerides (p &lt; 0.001), fasting plasma glucose (p &lt; 0.001), body mass index (p &lt; 0.001), systolic and diastolic blood pressure (p = 0.001 and p = 0.03) and C-reactive protein (p = 0.001). Furthermore, high plasma iTFA levels were associated with higher education and less smoking and alcohol consumption. We found that plasma ruminant trans fatty acids (rTFA) levels were favorably associated with CV risk factors. Furthermore, plasma iTFA levels were inversely associated with CV risk factors. However, our results might have been driven by lifestyle factors. Overall, our findings suggest that the current low intake of iTFAs in Norway does not constitute a threat to CV health.

  Abstract Purpose A high intake of marine n-3 polyunsaturated fatty acids (PUFAs) might improve cardiovascular (CV) health. We conducted a cross-sectional study to investigate associations between plasma phospholipid levels of marine n-3 PUFAs and CV risk factors, educational level, physical activity and smoking habits. Methods A total of 3706 individuals from a general population, all born in 1950 and residing in Akershus County, Norway, were included in this study. The main statistical approach was multivariable adjusted linear regression. Results Plasma marine n-3 PUFA levels ranged from 2.7 to 20.3 wt%, with a median level of 7.7 wt% (interquartile range 4.3–11.1 wt%). High levels of plasma marine n-3 PUFAs were associated with lower serum triglycerides [Standardized regression coefficient (Std.β-coeff.) − 0.14, p < 0.001], body mass index (Std. β-coeff. −0.08, p < 0.001), serum creatinine (Std. β-coeff. -0.03, p = 0.05), C-reactive protein levels (Std. β-coeff. – 0.03, p = 0.04), higher levels of serum high-density lipoprotein cholesterol (Std. β-coeff. 0.08, p < 0.001) and low-density lipoprotein cholesterol (Std. β-coeff. 0.04, p = 0.003). High levels of plasma marine n-3 PUFAs were also associated with lower glycated hemoglobin (Std. β-coeff. – 0.04, p = 0.01), however, only in individuals without diabetes. We found no associations between plasma marine n-3 PUFA levels and fasting plasma glucose or carotid intima-media thickness. High levels of plasma marine n-3 PUFAs were associated with higher educational level, more physical activity and lower prevalence of smoking. Conclusion In this cross-sectional study of Norwegian individuals born in 1950, high levels of plasma marine n-3 PUFAs were favourably associated with several CV risk factors, suggesting that fish consumption might improve CV health.

Carotid Atherosclerosis is Associated with Middle Cerebral Artery Pulsatility Index. Journal of Neuroimaging (JON). ISSN 1051-2284. doi: 10.1111/jon.12684. Fulltekst i vitenarkiv Vis sammendrag

  BACKGROUND AND PURPOSE Pulsatility index (PI) in the middle cerebral artery (MCA) is considered a measure of peripheral vascular resistance. Several established cardiovascular risk factors are common for both MCA PI and carotid atherosclerosis. Accordingly, in the present study we hypothesized an association between ultrasound‐derived indices of carotid atherosclerosis and MCA PI. METHODS All residents in Akershus County, born in 1950, were invited to a cardiovascular examination, The Akershus Cardiac Examination (ACE) 1950 Study (2012‐2015). A thorough ultrasound examination was performed to assess indices of atherosclerosis in the carotid arteries, and PI in the MCAs. In all, 3154 (85.1%) had adequate transcranial and carotid data. Associations between indices of carotid atherosclerosis and MCA PI were assessed by regression analyses adjusted for established cardiovascular risk factors. RESULTS Mean age was 64 (standard deviation [SD]: .6) years, and 1,357 (43%) were women. Mean MCA PI was .97 (SD: .17). Participants in the upper quartile of MCA PI had higher pulse pressure, more frequently hypertension, diabetes mellitus, and a history of coronary artery disease. Both carotid plaque score (B .007 [95% CI: .003‐.010]) and carotid intimamedia thickness (B .173 [95% CI: .120‐.226]) were significantly associated with MCA PI in adjusted analysis. The model R 2 was .055. CONCLUSION In a population‐based sample of middle‐aged adults, ultrasound‐derived indices of carotid atherosclerosis were independently associated with MCA PI. However, the overall explained variance of MCA PI was low, suggesting other factors than atherosclerosis and cardiovascular risk factors to play an important role for MCA PI.

  Objective: We assessed the impact of a single time-point measurement of SBP, DBP and pulse pressure at the age of 40, on carotid plaque burden, echolucent plaques and carotid intima–media thickness late midlife. Methods: Individuals participating in two separate studies, 23 years apart, defined our cohort (n = 2714). ‘The Age 40 Program’, a nationwide Norwegian cardiovascular screening survey, performed 1985–1999, assessed cardiovascular risk factors and lifestyle variables at age 40. ‘The ACE 1950 Study’, a population-based cohort study on individuals born in 1950, performed 2012–2015, included ultrasound examinations of the carotid arteries. Blood pressure (BP) determinants of carotid atherosclerosis were assessed by regression models adjusted for cardiovascular risk factors at age 40, and late midlife BP. Results: The participants, 50.3% women, had a mean age of 40 (SD 0.3) years in the first study, and 64 (SD 0.6) years in the second. At age 40, mean SBP was 128 (SD 14) mmHg, mean DBP was 78 (SD 10) mmHg and mean pulse pressure was 50 (SD 9) mmHg. SBP and DBP at age 40 predicted carotid plaque burden in late midlife. Only DBP predicted echolucent plaques, and none of the BP components predicted carotid intima–media thickness. Conclusion: A single time-point measurement of SBP and DBP at age 40 is associated with carotid plaque burden late midlife, also after adjustment for other cardiovascular risk factors at age 40, and of late midlife BP. Our findings emphasize the strong association between BP and atherosclerosis.

  Background New data on extracranial carotid atherosclerosis are needed, as improved ultrasound techniques may detect more atherosclerosis, the definition of plaque has changed over the years, and better cardiovascular risk control in the population may have changed patterns of carotid arterial wall disease and actual prevalence of established cardiovascular disease. We investigated the prevalence of atherosclerotic carotid plaques and carotid intima–media thickness (cIMT) and their relation to cardiovascular risk factors in a middle‐aged cohort from the general population. Methods and Results We performed carotid ultrasound in 3683 participants who were born in 1950 and included in a population‐based Norwegian study. Carotid plaque and cIMT were assessed according to the Mannheim Carotid Intima–Media Thickness and Plaque Consensus, and a carotid plaque score was used to calculate atherosclerotic burden. The participants were aged 63 to 65 years, and 49% were women. The prevalence of established cardiovascular disease was low (10%), but 62% had hypertension, 53% had hypercholesterolemia, 11% had diabetes mellitus, and 23% were obese. Mean cIMT was 0.73±0.11 mm, and atherosclerotic carotid plaques were present in 87% of the participants (median plaque score: 2; interquartile range: 3). Most of the cardiovascular risk factors, with the exception of diabetes mellitus, obesity and waist–hip ratio, were independently associated with the plaque score. In contrast, only sex, hypertension, obesity, current smoking, and cerebrovascular disease were associated with cIMT. Conclusions We found very high prevalence of carotid plaque in this middle‐aged population, and our data support a greater association between cardiovascular risk factors and plaque burden, compared with cIMT.

Incidence and severity of cancer-therapy-related cardiac dysfunction during contemporary breast cancer therapy in a real-world cohort. Fulltekst i vitenarkiv Vis sammendrag

  Background: Cancer therapy-related cardiac dysfunction (CTRCD) is a well-known complication in breast cancer patients exposed to anthracyclines and Human Epidermal Growth Factor Receptor 2 (HER2) targeted therapy. However, the incidence of CTRCD in unselected contemporary breast cancer populations treated according to current standard-of-care regimens remains incompletely investigated. Purpose: To determine the incidence of CTRCD in women receiving (neo-)adjuvant breast cancer therapy in a real-world setting. Methods: In this prospective observational study, women scheduled for (neo-)adjuvant breast cancer therapy were included. Participants were categorized into three treatment regimen groups: 1) anthracycline therapy only, 2) HER2-targeted therapy only, and 3) sequential treatment with anthracycline therapy followed by HER2-targeted therapy. The primary endpoint was the incidence of CTRCD, defined according to the echocardiographic criteria included in the 2022 ESC Cardio-Oncology Guidelines (Figure 1), from baseline to 12 months after completion of scheduled therapy. Echocardiography was assessed at baseline, after completion of scheduled therapy, and 12 months thereafter. In addition, echocardiography was performed every 3 months during HER2-targeted therapy and when clinically indicated. Results: In total, 515 women were included (median age: 53 years (IQR 45,64)). During follow-up, 123 (24%) developed CTRCD. Of these, 78% were classified as mild, 19% moderate, and 2% severe. The highest incidence of CTRCD was observed among participants receiving sequential anthracycline therapy (EC90 x 4) and HER2-targeted therapy (Table 1). This regimen also had the highest incidence of moderate and severe CTRCD (13%), compared with 4% in the anthracycline-only group and 1% in the HER2-only group. Overall, severe CTRCD was observed in 0.6% of all study participants. The cumulative incidence of the worst observed severity of CTRCD during follow-up, overall and by treatment regimen, is summarized in Table 1. Conclusion: In this real-world breast cancer cohort, nearly one in four women developed CTRCD during follow-up; however, most cases were categorised as mild. Moderate and severe cardiac dysfunction were primarily observed in patients receiving sequential anthracycline and HER2-targeted therapy. Severe CTRCD was rare in the overall study population.

  Background: Anthracycline and Human Epidermal Growth Factor Receptor 2 (HER2) targeted therapy may induce cancer therapy-related cardiac dysfunction (CTRCD). Current guidelines recommend risk stratification using the Heart Failure Association–International Cardio-Oncology Society (HFA-ICOS) risk assessment tool. However, data on the incidence of CTRCD in contemporary breast cancer populations treated according to current standard-of-care regimens remain limited. Moreover, the actual cardiovascular risk associated with the HFA-ICOS risk categories in breast cancer treatment remains uncertain. Real-world evaluation of whether this consensus-based stratification appropriately separates patients according to subsequent CTRCD risk has been highlighted as a key research priority. Purpose: Overall, the study aims to determine the incidence of CTRCD and to evaluate cardiovascular risk stratification using the HFA-ICOS tool and its association with subsequent CTRCD. Methods: CARE is a prospective observational study including women scheduled for (neo)adjuvant anthracycline therapy and/or HER2-targeted therapy. Echocardiography, using standard and novel echocardiographic parameters, and circulating cardiac biomarkers were assessed at baseline (visit 1), after completion of scheduled therapy (visit 2), and 12 months after completion of scheduled therapy (visit 3). Participants were categorized into three treatment regimen groups: 1) Anthracycline therapy only, 2) HER2-targeted therapy only, and 3) HER2-targeted therapy sequentially to anthracyclines (Figure 1). The primary outcome is incidence of CTRCD. Secondary outcomes include HFA-ICOS risk stratification in relation to subsequent CTRCD. Results: In total, 515 women (median age (Q1,Q3): 53 (45,64) years) were included. Overall, 335 (63%) participants received anthracycline therapy only, 100 (15%) received HER2-targeted therapy only, and 80 (19%) received anthracycline therapy followed by HER2-targeted therapy. Baseline cardiovascular risk factors included hypertension in 20%, current smoking in 13%, diabetes in 7%, and a history of heart disease in 7.6%, while 3.5% had received previous anti-cancer treatment (Table 1). Conclusion: The CARE study is a large prospective observational cardio-oncology study evaluating the incidence of CTRCD after contemporary breast cancer therapy regimens. With systematic echocardiographic and biomarker assessment, the study will provide important insights into the incidence of CTRCD, the performance of the HFA-ICOS risk stratification tool and follow-up strategies in routine cardio-oncology care.Table 1Baseline Characteristics CARE  Figure 1Consort Diagram
