  • Association of Long-Term Diet Quality with Hippocampal Volume : Longitudinal Cohort Study
  • 2018
  • Ingår i: American Journal of Medicine. - 0002-9343 .- 1555-7162. ; 131:11, s. 1372-1381.e4

    • Background: Diet quality is associated with brain aging outcomes. However, few studies have explored in humans the brain structures potentially affected by long-term diet quality. We examined whether cumulative average of the Alternative Healthy Eating Index 2010 (AHEI-2010) score during adult life (an 11-year exposure period) is associated with hippocampal volume.Methods: Analyses were based on data from 459 participants of the Whitehall II imaging sub-study (mean age [standard deviation] (SD) = 59.6 [5.3] years in 2002-2004, 19.2% women). Multimodal magnetic resonance imaging examination was performed at the end of follow-up (2015-2016). Structural images were acquired using a high-resolution 3-dimensional T1-weighted sequence and processed with Functional Magnetic Resonance Imaging of the Brain Software Library (FSL) tools. An automated model-based segmentation and registration tool was applied to extract hippocampal volumes.Results: Higher AHEI-2010 cumulative average score (reflecting long-term healthy diet quality) was associated with a larger total hippocampal volume. For each 1 SD (SD = 8.7 points) increment in AHEI-2010 score, an increase of 92.5 mm3 (standard error = 42.0 mm3) in total hippocampal volume was observed. This association was independent of sociodemographic factors, smoking habits, physical activity, cardiometabolic health factors, cognitive impairment, and depressive symptoms, and was more pronounced in the left hippocampus than in the right hippocampus. Of the AHEI-2010 components, no or light alcohol consumption was independently associated with larger hippocampal volume.Conclusions: Higher long-term AHEI-2010 scores were associated with larger hippocampal volume. Accounting for the importance of hippocampal structures in several neuropsychiatric diseases, our findings reaffirm the need to consider adherence to healthy dietary recommendation in multi-interventional programs to promote healthy brain aging.

  • Quantitative ST-depression in Acute Coronary Syndromes : the PLATO Electrocardiographic Substudy
  • 2013
  • Ingår i: American Journal of Medicine. - 0002-9343 .- 1555-7162. ; 126:8, s. 723-
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: We evaluated whether electrocardiogram (ECG) characteristics were aligned with clinical outcomes and the effect of ticagrelor within the diverse spectrum of non-ST-elevation acute coronary syndrome patients enrolled in the PLATelet inhibition and patient Outcomes (PLATO) trial. METHODS: There were 8884 PLATO patients who had baseline ECGs assessed by a core laboratory; of these, 4935 had an ECG at hospital discharge that also was assessed. Associations with study treatment on vascular death or myocardial infarction within 1 year were examined. RESULTS: At baseline, most patients had either no or <= 0.5 mm of ST-segment depression (57%); 26% had 1.0 mm, and 17% had more extensive depression (>1.0 mm). Across the baseline ST-segment depression strata, there was a consistent treatment benefit with ticagrelor versus clopidogrel on vascular death/myocardial infarction. The extent of residual ST-segment depression at discharge was similar in the treatment groups, and the treatment effect did not differ by the extent of discharge ST-segment depression. There was a progressive increase in vascular death/myocardial infarction with increasing extent of baseline ST-segment depression (1.0 mm [vs no/0.5 mm]: hazard ratio [HR] 1.22; 95% confidence interval [CI], 1.03-1.45; > 1.0 mm: HR 1.49; 95% CI, 1.24-1.78; P < .001) and at discharge (HR 1.28; 95% CI, 1.02-1.61; HR 2.13; 95% CI, 1.54-2.95; P <. 001). CONCLUSION: The treatment effect of ticagrelor among non-ST-segment-elevation acute coronary syndrome patients was consistently expressed across all baseline ST-segment depression strata. There was no indication of an anti-ischemic benefit of ticagrelor as reflected on the discharge ECG. Our data affirm the independent prognostic relationship of both baseline and hospital discharge ST-segment depression on outcomes within 1 year in non-ST-segment-elevation acute coronary syndrome patients.

  • Impact on long-term mortality of presence of obstructive coronary artery disease and classification of myocardial infarction.
  • Ingår i: The American journal of medicine. - : Elsevier. - 1555-7162 .- 0002-9343. ; 129:4, s. 398-406
  • Tidskriftsartikel (refereegranskat)abstract
    • In contrast to the associated with thromboembolic event type 1 myocardial infarction, type 2 myocardial infarction is caused by acute imbalance between oxygen supply and demand of myocardium. Type 2 myocardial infarction may be present in patients with or without obstructive coronary artery disease, but knowledge about patient characteristics, treatments, and outcome in relation to coronary artery status is lacking. We aimed to compare background characteristics, triggering mechanisms, treatment and long-term prognosis in large real-life cohort of patients with type 1 and type 2 myocardial infarction with and without obstructive coronary artery disease.

  • Prospective Risk of Rheumatologic Disease Associated with Occupational Exposure in a Cohort of Male Construction Workers
  • 2015
  • Ingår i: American Journal of Medicine. - : Elsevier. - 0002-9343 .- 1555-7162. ; 128:10, s. 1094-1101
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The association between occupational exposure and autoimmune disease is well recognized for silica, and suspected for other inhalants. We used a large cohort to estimate the risks of rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, and dermatomyositis associated with silica and other occupational exposures. METHODS: We analyzed data for male Swedish construction industry employees. Exposure was defined by a job-exposure matrix for silica and for other inorganic dusts; those with other job-exposure matrix exposures but not to either of the 2 inorganic dust categories were excluded. National hospital treatment data were linked for International Classification of Diseases, 10th Revision-coded diagnoses of rheumatoid arthritis (seronegative and positive), systemic lupus erythematosus, systemic sclerosis, and dermatomyositis. The 2 occupational exposures were tested as independent predictors of prospective hospital-based treatment for these diagnoses using age-adjusted Poisson multivariable regression analyses to calculate relative risk (RR). RESULTS: We analyzed hospital-based treatment data (1997 through 2010) for 240,983 men aged 30 to 84 years. There were 713 incident cases of rheumatoid arthritis (467 seropositive, 195 seronegative, 51 not classified) and 128 cases combined for systemic lupus erythematosus, systemic sclerosis, and dermatomyositis. Adjusted for smoking and age, the 2 occupational exposures (silica and other inorganic dusts) were each associated with increased risk of rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, and dermatomyositis combined: RR 1.39 (95% confidence interval [CI], 1.17-1.64) and RR 1.31 (95% CI, 1.11-1.53), respectively. Among ever smokers, both silica and other inorganic dust exposure were associated with increased risk of rheumatoid arthritis (RRs 1.36; 95% CI, 1.11-1.68 and 1.42; 95% CI, 1.17-1.73, respectively), while among never smokers, neither exposure was associated with statistically significant increased risk of rheumatoid arthritis. CONCLUSION: This analysis reaffirms the link between occupational silica and a range of autoimmune diseases, while also suggesting that other inorganic dusts may also impart excess risk of such disease.

  • Prevalence of Anxiety and Depression Symptoms in Patients with Myocardial Infarction with Non-Obstructive Coronary Arteries
  • 2018
  • Ingår i: American Journal of Medicine. - 0002-9343 .- 1555-7162. ; 131:9, s. 1118-1124
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Myocardial infarction with non-obstructive coronary arteries is a working diagnosis for several heart disorders. Previous studies on anxiety and depression in patients with myocardial infarction with non-obstructive coronary arteries are lacking. Our aim was to investigate the prevalence of anxiety and depression among patients with myocardial infarction with non-obstructive coronary arteries. METHODS: We included 99 patients with myocardial infarction with non-obstructive coronary arteries together with age- and sex-matched control groups who completed the Beck Depression Inventory and the Hospital Anxiety and Depression Scale (HADS) 3 months after the acute event. RESULTS: Using the Beck Depression Inventory, we found that the prevalence of depression in patients with myocardial infarction with non-obstructive coronary arteries (35%) was higher than in healthy controls (9%; P = .006) and similar to that of patients with coronary heart disease (30%; P = .954). Using the HADS anxiety subscale, we found that the prevalence of anxiety in patients with myocardial infarction with non-obstructive coronary arteries (27%) was higher than in healthy controls (9%; P = .002) and similar to that of patients with coronary heart disease (21%; P = .409). Using the HADS depression subscale, we found that the prevalence of depression in patients with myocardial infarction with non-obstructive coronary arteries (17%) was higher than in healthy controls (4%; P = .003) and similar to that of patients with coronary heart disease (13%; P = .466). Patients with myocardial infarction with non-obstructive coronary arteries and takotsubo syndrome scored higher on the HADS anxiety subscale than those without (P = .028). CONCLUSIONS: This is the first study on the mental health of patients with myocardial infarction with non obstructive coronary arteries to show that prevalence rates of anxiety and depression are similar to those in patients with coronary heart disease.

  • Myocardial Infarction with Non-Obstructive Coronary Arteries : The Importance of Achieving Secondary Prevention Targets
  • 2018
  • Ingår i: ; 131:5, s. 524-531
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Around 5-10% of all myocardial infarction patients have non-obstructive coronary arteries. Studies investigating the importance of follow-up and achievement of conventional secondary prevention targets in these patients are lacking.METHODS: In this analysis from the SWEDEHEART registry, we investigated 5830 myocardial infarction patients with non-obstructive coronary arteries (group 1) and 54,637 myocardial infarction patients with significant coronary artery disease (≥50% stenosis; group 2). Multivariable- and propensity score-adjusted statistics were used to assess the reduction in the one-year risk of major adverse events associated with prespecified secondary preventive measures: participation in follow-up at 6-10 weeks after the hospitalization; achievement of secondary prevention targets (blood pressure and low-density lipoprotein cholesterol levels in the target ranges, non-smoking, participation in exercise training).RESULTS: Patients in group 1 were less often followed up compared to patients in group 2 and less often achieved any of the secondary prevention targets. Participation in the 6-10 week follow-up was associated with a 3-20% risk reduction in group 1, similar as for group 2 according to interaction analysis. The improvement in outcome in group 1 was mainly mediated by achieving target range low-density lipoprotein cholesterol levels (24-32% risk reduction) and, to a smaller extent, by participation in exercise training (10-23% risk reduction).CONCLUSIONS: Selected secondary preventive measures are associated with prognostic benefit in myocardial infarction patients with non-obstructive coronary arteries, in particular achieving target range low-density lipoprotein cholesterol levels. Our results indicate that these patients should receive similar follow-up as myocardial infarction patients with significant coronary stenoses.

    • BACKGROUND:Approximately 5% to 10% of all patients with myocardial infarction have nonobstructive coronary arteries. Studies investigating the importance of follow-up and achievement of conventional secondary prevention targets in these patients are lacking.METHODS:In this analysis from the Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART) registry, we investigated 5830 patients with myocardial infarction with nonobstructive coronary arteries (group 1) and 54,637 patients with myocardial infarction with significant coronary artery disease (≥50% stenosis; group 2). Multivariable- and propensity score-adjusted statistics were used to assess the reduction in the 1-year risk of major adverse events associated with prespecified secondary preventive measures: participation in follow-up at 6 to 10 weeks after the hospitalization and achievement of secondary prevention targets (blood pressure and low-density lipoprotein cholesterol levels in the target ranges, nonsmoking, and participation in exercise training).RESULTS:Patients in group 1 were less often followed up compared with patients in group 2 and less often achieved any of the secondary prevention targets. Participation in the 6- to 10-week follow-up was associated with a 3% to 20% risk reduction in group 1, similar as for group 2 according to interaction analysis. The improvement in outcome in group 1 was mainly mediated by achieving target range low-density lipoprotein cholesterol levels (24%-32% risk reduction) and, to a smaller extent, by participation in exercise training (10%-23% risk reduction).CONCLUSIONS:Selected secondary preventive measures are associated with prognostic benefit in patients with myocardial infarction with nonobstructive coronary arteries, in particular achieving target range low-density lipoprotein cholesterol levels.

  • Unstable Angina in the Era of Cardiac Troponin Assays with Improved Sensitivity-A Clinical Dilemma
  • 2017
  • Ingår i: ; 130:12, s. 1423-1430
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: There is an expectation that with the adoption of more sensitive cardiac troponin (cTn) assays, unstable angina would become a rarity. However, recent data from the SWEDEHEART registry demonstrated that 15% of patients admitted with non-ST-elevation acute coronary syndrome still were regarded as having unstable angina. We aimed to further investigate the clinical characteristics and outcome of these patients. METHODS: This was a retrospective, registry-based analysis (SWEDEHEART) including 3204 unstable patients, 18,194 non-ST-elevation myocardial infarction (NSTEMI) patients, and 977 controls without acute cardiovascular disease. All patients had available data on peak cTnT levels (more sensitive assay) and 1-year outcome. RESULTS: The annual proportions of patients with unstable angina (2009-2013) among those with non-STelevation acute coronary syndrome ranged from 9.4% to 15.3%. Only 1239 unstable angina patients (39.7%) had a peak cTnT level = 14 ng/L. Patients with unstable angina tended to be younger than those with NSTEMI but had higher prevalence of most cardiovascular risk factors and more advanced coronary artery disease. Compared with controls, the adjusted hazard ratios (95% confidence interval) regarding major cardiovascular events were 2.97 (1.30-6.78) and 5.44 (2.54-11.65) in unstable angina patients with peak cTnT = 14 ng/L and > 14 ng/L, respectively. CONCLUSION: The diagnosis of unstable angina is still commonly used, even in the era of more sensitive cTn assays. Minor cTnT elevation is common, which makes unstable angina difficult to distinguish from NSTEMI. Patients with unstable angina have a nonneglectable cardiovascular risk. We suggest that the clinical management of patients presenting with unstable symptoms should depend on their estimated cardiovascular risk rather than on strictly applied diagnostic criteria.
