Journal article (peer-reviewed)abstract
- Background Sex-differences in the pathobiology of myocardial infarction are well established but incompletely understood. Improved knowledge on this topic may help clinicians to improve management of men and women with myocardial infarction. Methods In this registry-based cohort study (SWEDEHEART), we analyzed 175 circulating biomarkers reflecting various pathobiological axes in 856 men and 243 women admitted to Swedish coronary care units because of myocardial infarction. Two multimarker panels were applied (Proximity Extension Assay [Olink Bioscience], Multiple Reaction Monitoring mass spectrometry). Lasso analysis (penalized logistic regression), multiple testing-corrected Mann- Whitney tests and Cox regressions were used to assess sex-differences in the concentrations of these biomarkers and their implications on all-cause mortality and major adverse events (median follow-up up to 6.6 years). Results Biomarkers provided a very high discrimination between both sexes, when considered simultaneously (c-statistics 0.972). Compared to women, men had higher concentrations of six biomarkers with the most pronounced differences seen for those reflecting atherogenesis, myocardial necrosis and metabolism. Women had higher concentrations of 14 biomarkers with the most pronounced differences seen for those reflecting activation of the reninangiotensin- aldosterone axis, inflammation and for adipokines. There were no major variations between sexes in the associations of these biomarkers with outcome. Conclusions Severable sex-differences exist in the expression of biomarkers in patients with myocardial infarction. While these differences had no impact on outcome, our data suggest the presence of various sex-related pathways involved in the development of coronary atherosclerosis, the progression to plaque rupture and acute myocardial damage, with a greater heterogeneity in women.

In: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 32:11, s. 1331-1336
-
Journal article (peer-reviewed)abstract
- Aims The main purpose of the present study was to analyse the contemporary use of cardiovascular medications and diagnostic coronary angiography in men and women with suspected coronary artery disease (CAD). Furthermore, we examined the association of outcomes (death, myocardial infarction, repeat coronary angiography, procedural complications) with angiographic findings.Methods All patients with stable chest pain (n = 12 200) referred for a first-time elective diagnostic coronary angiography during 2006-08 and registered in the Swedish Coronary Angiography and Angioplasty Register (SCAAR) were included. Significant CAD was defined as ≥50% luminal narrowing in any epicardial coronary artery.Results In the youngest age group (≤59 years), more women than men (78.8 vs. 42.3%, P< 0.001) had normal/non-significant CAD, whereas more men had either left-main or three-vessel disease (18.2 vs. 4.2%, P < 0.001). Event rates were similarly low for men and women with normal/non-significant CAD, except for a higher procedural complication rate in women. Prior to angiography, fewer women than men with high-risk features were prescribed aspirin (83 vs. 86.1%, P = 0.001).Conclusion In women, normal/non-significant CAD was highly prevalent, especially among younger women, and associated cardiovascular event rates were low. In men, findings of advanced disease were more common than in women, even younger men. Fewer high-risk women than men were initially prescribed aspirin. The observed sex differences suggest a need for improved identification of women appropriate for investigation with coronary angiography, earlier diagnostics in men, and heightened attention in the evidence-based use of aspirin in risk patients, especially women.

Low-Density Lipoprotein Oxidation and Renal Dysfunction : New Markers of Poor Prognosis in Patients with Unstable Coronary Artery Disease
- 2006
-
Doctoral thesis (other academic/artistic)abstract
- In patients with unstable coronary artery disease (CAD) biochemical markers are emerging as useful tools in clinical management. In this thesis we studied the use of markers of low-density lipoprotein (LDL) oxidation and renal function.Our study populations consisted of unstable CAD patients included in the Fast Revascularisation during Instability in Coronary artery disease (FRISC)-II trial and healthy controls. Patients were followed for 2 years regarding death and myocardial infarction (MI).Using receiver operating characteristic curve analysis, we found that oxidized low-density lipoprotein (OxLDL), especially when combined with high-density lipoprotein, compared to traditionally measured lipids/lipoproteins, and a new lipoprotein marker, lipoprotein associated-phospholipase A2, was better at discriminating between healthy controls and CAD patients. In patients, OxLDL was found to be an independent prognostic marker associated with an increased risk of MI, of particular use in patients with no evidence of myocardial necrosis. In our study on the effects of an early invasive treatment strategy in unstable CAD patients with mild to moderate renal dysfunction (i.e. creatinine clearance <90mL/min) we found that in patients randomized to invasive treatment, the rates of death/MI and MI alone were significantly lower than in patients randomized to non-invasive treatment. In patients treated invasively, no detrimental effects were seen on renal function at follow-up at 6 months. In healthy controls, we investigated new markers of renal (cystatin C) and cardio-renal function (N-terminal probrain natriuretic peptide, [NT-proBNP]) regarding reference levels and physiological determinants. We found that cystatin C is influenced by age whereas NT-proBNP is influenced by age and gender.Our studies suggest that OxLDL and renal dysfunction are associated with a poor prognosis in unstable CAD patients and that these markers demonstrate potential for clinical use. In the search for new markers related to renal function we have contributed with reference levels of cystatin C and NT-proBNP.

Systematic reviews : causes of non-adherence to P2Y12 inhibitors in acute coronary syndromes and response to intervention
- 2016
-
In: Open heart. - : BMJ. - 2053-3624. ; 3:2
-
Research review (peer-reviewed)abstract
- To understand the factors associated with non-adherence to oral antiplatelet (OAP) therapy in acute coronary syndromes (ACS), and where interventions have modified these factors. Linked systematic reviews were undertaken in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analysis guidelines, using CINAHL Plus, MEDLINE, PsycINFO and PubMed databases. The searches were limited to studies available in English and published from 2000 onwards; last run in June 2015. Review 1: factors. Fifteen articles were identified that reported 25 different factors associated with OAP non-adherence. Factors were categorised into: Demographic, Treatment, Healthcare System Processes, Clinical, Opportunity (ie, factors outside the patients, such as cost and healthcare access) and Psychosocial. It was not possible to determine if any of these factors were more impactful than others, either overall or temporally. Review 2: interventions. Six articles were identified that described interventions targeting adherence in patients with acute coronary syndromes (ACS)/coronary artery disease (CAD). Four broad categories of intervention were identified: treatment counselling and education, educational materials, SMS reminders and telephone monitoring and reinforcement delivered different practitioners. Only reminder-based interventions had a consistently successful impact on adherence outcomes at both 3 and 12 months. A number of factors are associated with OAP non-adherence, and encouragingly, there is some evidence of the effectiveness of intervention to modify treatment adherence in patients with ACS/CAD. Future evaluations ensuring a better cohesion between the factors studied as associated with non-adherence and those targeted by intervention would further increase understanding and lead to improved results.

Biochemical biomarkers associated with peripheral artery disease contribute to prediction of outcome during long-term follow up after myocardial infarction
-
Other publication (other academic/artistic)abstract
- AbstractBackground: Few studies have investigated biomarkers and their association to cardiovascular (CV) outcomes in patients with myocardial infarction (MI) and peripheral artery disease (PAD). Tumor necrosis factor receptor 1(TNFR-1), tumor necrosis factor receptor 2(TNFR-2) and growth differentiation factor 15 (GDF-15) are inflammatory biomarkers found to predict PAD.Aim: To evaluate whether pathological ankle brachial index (ABI) and the group of biomarkers TNFR-1, TNFR-2 and GDF-15 analyzed early after a MI, were associated with all-cause mortality and the risk of new cardiovascular events during long-term follow up. Method: 388 patients with MI included in the REBUS (Relevance of Biomarkers for future risk of Thromboembolic Events in Unselected Post-myocardial Infarction Patients) study were examined with ABI to diagnose PAD (defined as an ABI score <0.9 or > 1.4 on at least one side). TNFR-1, -2 and GDF-15 was measured using the Proseek Multiplex CVD III ⁹⁶˟⁹⁶ proximity extension assay (www.olink.com/products/cvd-i and iii-panel). The composite results for these 3 biomarkers were dichotomized into two groups (i.e high and low values) We evaluated pathological ABI and the group with higher biomarkers values with the association to long-term outcome, and if the group of biomarkers for inflammation could further improve prediction of recurrence of cardiovascular events (mortality, new acute coronary syndrome (ACS) and the composite of mortality, new ACS, stroke/TIA and PAD) after an MI. Results: The mean follow-up time was 5.5 years. After adjustment for established CV risk factors, pathological ABI was associated with a higher risk of new ACS, HR 1.97, 95 % CI 1.12-3.49, p = 0.019, and the composite endpoint; HR 1.97, 95 % CI 1.29-3.01, p=0.002, compared to patients with normal ABI. The group with the higher biomarker value was associated with a higher risk for all-cause mortality; HR 1.84, 95 % CI 1.00-3.38, p=0.049 and the composite endpoint; HR 1.62, 95 % CI 1.03-2.53, p=0.035. In the ROC analyses pathological ABI added to established CV risk factors improved the AUC for a new ACS from 0.753 (95% C.I. 0.684-0.822, p<0.001) to 0.763 (95% C.I. 0.697-0.830, p<0.001). When the group with higher biomarker values was added to established CV risk factors AUC for all-cause mortality increased from 0.789 (95% C-I. 0.729-0.849, p<0.001) to 0.805 (95% C.I. 0.746-0.863, p<0.001).Conclusion: Despite a high proportion of revascularization and guideline-recommended secondary medical treatment, both pathological ABI and the group with higher values of the inflammatory biomarkers (TNFR-1, TNFR-2, GDF-15) predictive for PAD were associated with the risk of new CV events and mortality in patients with a recent MI. The group of inflammatory biomarkers provide additional information to established risk factors in prediction of CV outcome in this cohort with recent MI.

Importance of peripheral arterial disease as a risk marker in patients with myocardial infarction
- 2019
-
Doctoral thesis (other academic/artistic)abstract
- The purpose of this thesis was to describe the true prevalence of widespread arterial disease in a cohort with patients with a recent myocardial infarction (MI) to find valuable clinical methods to detect these patients. Our aim was also to investigate biomarker relationships with peripheral artery disease (PAD) and the importance of PAD in patients’ long-term outcomes.We studied patients with a recent MI in a prospective observational study, the REBUS ((Relevance of Biomarkers for Future Risk of Thromboembolic Events in Unselected Post-myocardial Infarction Patients) trial. A total of 421 patients were included in the study, 390 of whom had their ankle-brachial index (ABI) measured and a mean-time follow up of 5.5 years. Atherosclerotic changes were assessed in three arterial beds by coronary angiography, measuring the ABI and carotid ultrasound. Ninety-two biochemical biomarkers were assessed at baseline by a proximity extension assay (PEA) chip. 263 out of 421 filled in a self-administered Walking Impairment Questionnaire (WIQ). Polyvascular (PvD) disease was defined as pathological findings in all three arterial beds.We found that PAD and PvD are underdiagnosed in patients who suffered a recent MI. We also found the ABI to be a strong and useful method to identify patients with PAD as well as patients with more widespread arterial disease, such as PvD (paper I).The results of the scoring system, the WIQ, showed it is useful for finding patients with PAD and PvD, even when completed soon after an acute MI event (paper II).We also found that biochemical biomarkers associated with the inflammatory pathway – tumour necrosis factor receptor 1 (TNFR-1), tumor necrosis factor receptor 2 (TNFR-2) and growth differentiation factor 15 (GDF-15) – were able to predict pathological ABI, i.e. PAD, in these MI patients. These results could also be validated in another observational study and cohort of MI patients, the VaMIS cohort (paper III). Pathological ABI was also found to be a strong predictor for cardiovascular events of all-cause mortality, new ACS, and a composite endpoint of all-cause mortality, new ACS, new stroke/TIA or new PAD event. When evaluating the three inflammatory biomarkers as a surrogate marker for ABI, they showed a similar association with all-cause death and the composite endpoint (paper IV).

Low Walking Impairment Questionnaire score after a recent myocardial infarction identifies patients with polyvascular disease
- 2019
-
In: JRSM Cardiovascular Disease. - : SAGE Publications. - 2048-0040. ; 8, s. 1-9
-
Journal article (peer-reviewed)abstract
- Objectives: To evaluate whether the Walking Impairment Questionnaire score could identify patients with polyvascular disease in a population with recent myocardial infarction and their association with cardiovascular events during two-year follow-up.Design: A prospective observational study.Setting: Patients admitted to the acute coronary care unit, the Department of Cardiology, Uppsala University Hospital.Participants: Patients admitted with acute Non-STEMI- or STEMI-elevation myocardial infarction.Main outcome measures: The Walking Impairment Questionnaire, developed as a self-administered instrument to assess walking distance, speed, and stair climbing in patients with peripheral artery disease, predicts future cardiovascular events and mortality. Two hundred and sixty-three patients with recent myocardial infarction answered Walking Impairment Questionnaire. Polyvascular disease was defined as abnormal findings in the coronary- and carotid arteries and an abnormal ankle-brachial index. The calculated score for each of all three categories were divided into quartiles with the lowest score in first quartile.Results: The lowest (worst) quartile in all three Walking Impairment Questionnaire categories was associated with polyvascular disease, fully adjusted; distance, odds ratio (OR) 5.4 (95% confidence interval (CI) 1.8-16.1); speed, OR 7.4 (95% CI 1.5-36.5); stair climbing, OR 8.4 (95% CI 1.0-73.6). In stair climbing score, patients with the lowest (worst) score had a higher risk for the composite cardiovascular endpoint compared to the highest (best) score; hazard ratio 5.3 (95% CI 1.5-19.0). The adherence to medical treatment was high (between 81.7% and 99.2%).Conclusions: The Walking Impairment Questionnaire is a simple tool to identify myocardial infarction patients with more widespread atherosclerotic disease and although well treated medically, stair climbing predicts cardiovascular events.

Medical students' self-reported gender discrimination and sexual harassment over time
- 2020
-
In: BMC Medical Education. - : Springer Science and Business Media LLC. - 1472-6920. ; 20:1
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Gender discrimination (GD) and sexual harassment (SH) occur at all academic institutions worldwide. Medical students report high prevalence of GD and SH, which may negatively affect their education and health. There are indications that policies and reforms on reducing GD/SH are insufficient. Swedish medical students' experiences of GD/SH are monitored by course-evaluations and bi-annual student union evaluations; however, the response rate is usually low. The aim of this study was to compare the exposure to and context of self-reported GD/SH over an 11-year period amongst medical students at a Swedish university.METHODS: In 2002, a questionnaire (n = 622) was mailed to medical students' home addresses. It was repeated in 2013 and then distributed during mandatory lectures (n = 856). The questions used a behavioristic approach and asked about specific GH/SH experiences. Participation was voluntary and anonymous. The changes in prevalence over time were calculated by sampling weights in order to obtain comparable estimates, representative of both cohorts.RESULTS: The response frequency was 55% (62% women) in 2002 and 81% (59% women) in 2013. The prevalence of GD tended to decrease for male and clinical students in comparison to female and pre-clinical peers. However, the prevalence of SH increased for female compared to male students. The ratio of SH for female pre-clinical students doubled in many instances; most often, the mistreatment occurred in the clinic. Medical doctors were indicated as perpetrators up to five times more often by all students in 2013.CONCLUSION: Our results show a disproportional change in exposure to GD/SH between female and male medical students, resulting in a widening of the gender gap regarding prevalence of GD and SH between 2002 and 2013. In particular, personal experiences of SH increased for both sexes. It is proof that institutional efforts to fight mistreatment might be ineffective.

Initial Invasive or Conservative Strategy for Stable Coronary Disease
- 2020
-
In: New England Journal of Medicine. - 0028-4793 .- 1533-4406. ; 382:15, s. 1395-1407
-
Journal article (peer-reviewed)abstract
- Background: Among patients with stable coronary disease and moderate or severe ischemia, whether clinical outcomes are better in those who receive an invasive intervention plus medical therapy than in those who receive medical therapy alone is uncertain.Methods: We randomly assigned 5179 patients with moderate or severe ischemia to an initial invasive strategy (angiography and revascularization when feasible) and medical therapy or to an initial conservative strategy of medical therapy alone and angiography if medical therapy failed. The primary outcome was a composite of death from cardiovascular causes, myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest. A key secondary outcome was death from cardiovascular causes or myocardial infarction.Results: Over a median of 3.2 years, 318 primary outcome events occurred in the invasive-strategy group and 352 occurred in the conservative-strategy group. At 6 months, the cumulative event rate was 5.3% in the invasive-strategy group and 3.4% in the conservative-strategy group (difference, 1.9 percentage points; 95% confidence interval [CI], 0.8 to 3.0); at 5 years, the cumulative event rate was 16.4% and 18.2%, respectively (difference, -1.8 percentage points; 95% CI, -4.7 to 1.0). Results were similar with respect to the key secondary outcome. The incidence of the primary outcome was sensitive to the definition of myocardial infarction; a secondary analysis yielded more procedural myocardial infarctions of uncertain clinical importance. There were 145 deaths in the invasive-strategy group and 144 deaths in the conservative-strategy group (hazard ratio, 1.05; 95% CI, 0.83 to 1.32).Conclusions: Among patients with stable coronary disease and moderate or severe ischemia, we did not find evidence that an initial invasive strategy, as compared with an initial conservative strategy, reduced the risk of ischemic cardiovascular events or death from any cause over a median of 3.2 years. The trial findings were sensitive to the definition of myocardial infarction that was used. (Funded by the National Heart, Lung, and Blood Institute and others; ISCHEMIA ClinicalTrials.gov number, .) Patients with stable coronary disease were randomly assigned to an initial invasive strategy with angiography and revascularization if appropriate or to medical therapy alone. At 3.2 years, there was no significant difference between the groups with respect to the estimated rate of ischemic events. The findings were sensitive to the definition of myocardial infarction.

Survival in Patients With Suspected Myocardial Infarction With Nonobstructive Coronary Arteries : A Comprehensive Systematic Review and Meta-Analysis From the MINOCA Global Collaboration
- 2021
-
In: Circulation. Cardiovascular Quality and Outcomes. - : Lippincott Williams & Wilkins. - 1941-7713 .- 1941-7705. ; 14:11
-
Research review (peer-reviewed)abstract
- BACKGROUND: Suspected myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA) occurs in ≈5% to 10% of patients with MI referred for coronary angiography. The prognosis of these patients may differ to those with MI and obstructive coronary artery disease (MI-CAD) and those without a MI (patients without known history of MI [No-MI]). The primary objective of this study is to evaluate the 12-month all-cause mortality of patients with MINOCA.METHODS: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the terms "MI," "nonobstructive," "angiography," and "prognosis" were searched in PubMed and Embase databases from inception to December 2018, including original, English language MINOCA studies with >100 consecutive patients. Publications with a heterogeneous cohort, unreported coronary stenosis, or exclusively focusing on MINOCA-mimicking conditions, were excluded. Unpublished data were obtained from the MINOCA Global Collaboration. Data were pooled and analyzed using Paule-Mandel, Hartung, Knapp, Sidik & Jonkman, or restricted maximum-likelihood random-effects meta-analysis methodology. Heterogeneity was assessed using Cochran's Q and I2 statistics. The primary outcome was 12-month all-cause mortality in patients with MINOCA, with secondary comparisons to MI-CAD and No-MI.RESULTS: The 23 eligible studies yielded 55 369 suspected MINOCA, 485 382 MI-CAD, and 33 074 No-MI. Pooled meta-analysis of 14 MINOCA studies accounting for 30 733 patients revealed an unadjusted 12-month all-cause mortality rate of 3.4% (95% CI, 2.6%-4.2%) and reinfarction (n=27 605; 10 studies) in 2.6% (95% CI, 1.7%-3.5%). MINOCA had a lower 12-month all-cause mortality than those with MI-CAD (3.3% [95% CI, 2.5%-4.1%] versus 5.6% [95% CI, 4.1%-7.0%]; odds ratio, 0.60 [95% CI, 0.52-0.70], P<0.001). In contrast, there was a statistically nonsignificant trend towards increased 12-month all-cause mortality in patients with MINOCA (2.6% [95% CI, 0%-5.9%]) compared with No-MI (0.7% [95% CI, 0.1%-1.3%]; odds ratio, 3.71 [95% CI, 0.58-23.61], P=0.09).CONCLUSIONS: In the largest contemporary MINOCA meta-analysis to date, patients with suspected MINOCA had a favorable prognosis compared with MI-CAD, but statistically nonsignificant trend toward worse outcomes compared to those with No-MI.

Journal article (peer-reviewed)abstract
- Adverse pregnancy outcomes are recognized risk enhancers for cardiovascular disease, but the prevalence of subclinical coronary atherosclerosis after these conditions is unknown.To assess associations between history of adverse pregnancy outcomes and coronary artery disease assessed by coronary computed tomography angiography screening.Cross-sectional study of a population-based cohort of women in Sweden (n=10528) with 1 or more deliveries in 1973 or later, ascertained via the Swedish National Medical Birth Register, who subsequently participated in the Swedish Cardiopulmonary Bioimage Study at age 50 to 65 (median, 57.3) years in 2013-2018. Delivery data were prospectively collected.Adverse pregnancy outcomes, including preeclampsia, gestational hypertension, preterm delivery, small-for-gestational-age infant, and gestational diabetes. The reference category included women with no history of these exposures.Coronary computed tomography angiography indexes, including any coronary atherosclerosis, significant stenosis, noncalcified plaque, segment involvement score of 4 or greater, and coronary artery calcium score greater than 100.A median 29.6 (IQR, 25.0-34.9) years after first registered delivery, 18.9% of women had a history of adverse pregnancy outcomes, with specific pregnancy histories ranging from 1.4% (gestational diabetes) to 9.5% (preterm delivery). The prevalence of any coronary atherosclerosis in women with a history of any adverse pregnancy outcome was 32.1% (95% CI, 30.0%-34.2%), which was significantly higher (prevalence difference, 3.8% [95% CI, 1.6%-6.1%]; prevalence ratio, 1.14 [95% CI, 1.06-1.22]) compared with reference women. History of gestational hypertension and preeclampsia were both significantly associated with higher and similar prevalence of all outcome indexes. For preeclampsia, the highest prevalence difference was observed for any coronary atherosclerosis (prevalence difference, 8.0% [95% CI, 3.7%-12.3%]; prevalence ratio, 1.28 [95% CI, 1.14-1.45]), and the highest prevalence ratio was observed for significant stenosis (prevalence difference, 3.1% [95% CI, 1.1%-5.1%]; prevalence ratio, 2.46 [95% CI, 1.65-3.67]). In adjusted models, odds ratios for preeclampsia ranged from 1.31 (95% CI, 1.07-1.61) for any coronary atherosclerosis to 2.21 (95% CI, 1.42-3.44) for significant stenosis. Similar associations were observed for history of preeclampsia or gestational hypertension among women with low predicted cardiovascular risk.Among Swedish women undergoing coronary computed tomography angiography screening, there was a statistically significant association between history of adverse pregnancy outcomes and image-identified coronary artery disease, including among women estimated to be at low cardiovascular disease risk. Further research is needed to understand the clinical importance of these associations.

Do self-reported pregnancy complications add to risk evaluation in older women with established cardiovascular disease?
- 2019
-
In: BMC Women's Health. - : Springer Science and Business Media LLC. - 1472-6874. ; 19:1
-
Journal article (peer-reviewed)abstract
- BACKGROUND: In postmenopausal women with established cardiovascular disease (CVD), it is unknown whether a history of pregnancy complications are related to multisite artery disease (MSAD), defined as atherosclerotic lesions in at least two major vascular beds. Pregnancy complications are an established risk factor for CVD. This study aimed to investigate the frequency of pregnancy complications and their association to specific atherosclerotic manifestations and prediction of MSAD in older women with and without CVD.METHODS: In total, 556 women were invited to participate in the study. Of these women 307 reported former pregnancy from a cohort of women with (n = 233) and without CVD (n = 74). The self-reported frequency of pregnancy complications were surveyed retrospectively by a questionnaire that included miscarriage, subfertility, gestational hypertension (GHT) and/or preeclampsia (PE), low birth weight, preterm birth, bleeding in late pregnancy, gestational diabetes mellitus and high birth weight. Three vascular beds were examined, the peripheral, carotid and coronary arteries.RESULTS: The mean age was 67.5 (SD 9.5) years. GHT and/or PE tended to be more common, but not significant, in women with CVD than in women without (20.3% vs 10.8%, p = 0.066). Among women with GHT and/or PE, hypertension later in life were more frequent than in women without (66.7% vs 47.4%, p = 0.010). GHT and/or PE were not associated with specific atherosclerotic manifestations or prediction of MSAD.CONCLUSIONS: In older women with established CVD, pregnancy complications was not associated to specific atherosclerotic manifestations and may not provide additional value to the risk evaluation for MSAD.

Journal article (peer-reviewed)abstract
- The aim of this study was to conduct a nationwide all comer description of incidence, contemporary management and outcome in Swedish spontaneous coronary artery dissection (SCAD) patients. The incidence of SCAD as well as the management and outcome of these patients is not well described.A nationwide observational study.All patients with SCAD registered in the Swedish Coronary Angiography and Angioplasty Register from 2015 to 2017 were included. The index angiographies of patients with registered SCAD were re-evaluated at each centre to confirm the diagnosis. Patients with non-SCAD myocardial infarction (MI) (n=32 601) were used for comparison.Outcomes included all-cause mortality, reinfarction or acute coronary reangiography.This study found 147 SCAD patients, rendering an incidence of 0.74 per 100 000 per year and a prevalence of 0.43% of all MIs. The average age was 52.9 years, 75.5% were women and 47.6% presented with ST-segment elevation MI. Median follow-up time for major adverse cardiac event was 17.3 months. Percutaneous coronary intervention was attempted in 40.1% of SCAD patients and 30.6% received stent. The use of antithrombotic agents was similar between the groups and there was no difference regarding outcomes, 10.9% vs 13.4%, p=0.75. Mortality was lower in SCAD patients, 2.7% vs 8.0%, p=0.03, whereas SCAD patients more often underwent acute reangiography, 9.5% vs 4.6%, p<0.01.In this nationwide, all comer Swedish study, the overall incidence of SCAD was low, including 25% men which is more and in contrast to previous studies. Compared with non-SCAD MI, SCAD patients were younger, with lower cardiovascular risk burden, yet suffered substantial mortality and morbidity and more frequently underwent acute coronary reangiography.
