    • Cardiopulmonary diseases are major causes of death worldwide, but currently recommended strategies for diagnosis and prevention may be outdated because of recent changes in risk factor patterns. The Swedish CArdioPulmonarybioImage Study (SCAPIS) combines the use of new imaging technologies, advances in large-scale 'omics' and epidemiological analyses to extensively characterize a Swedish cohort of 30 000 men and women aged between 50 and 64 years. The information obtained will be used to improve risk prediction of cardiopulmonary diseases and optimize the ability to study disease mechanisms. A comprehensive pilot study in 1111 individuals, which was completed in 2012, demonstrated the feasibility and financial and ethical consequences of SCAPIS. Recruitment to the national, multicentre study has recently started.

  • Cardiovascular autonomic neuropathy associated with carotid atherosclerosis in Type 2 diabetic patients.
  • 2003
  • Ingår i: Diabetic Medicine. - : Wiley. - 1464-5491 .- 0742-3071. ; 20:6, s. 495-499

    • AimsTo clarify if cardiovascular autonomic neuropathy is associated with carotid artery atherosclerotic plaques in Type 2 diabetic patients. MethodsCardiovascular autonomic nerve function was related to carotid artery ultrasound in 61 Type 2 diabetic patients 5-6 years after diagnosis of diabetes. ResultsCardiovascular autonomic neuropathy [abnormal age corrected expiration/inspiration (E/I) ratio or acceleration index (AI)] was found in 13/61 (21%) patients. Patients with cardiovascular autonomic neuropathy showed increased degree of stenosis in the common carotid artery (24.6 ± 13.2% vs. 14.7 ± 9.2%; P = 0.014) and a tendency towards a higher plaque score (4.0 ± 1.7 vs. 3.2 ± 1.6; P = 0.064). Controlled for age, AI correlated inversely with degree of stenosis (r = -0.39; P = 0.005), plaque score (r = -0.39; P = 0.005), and mean (r = -0.33; P = 0.018) and maximum (r = -0.39; P = 0.004) intima-media thickness in the common carotid artery. In contrast, E/I ratio correlated only slightly with mean intima-media thickness in the common carotid artery (r = -0.28; P = 0.049). ConclusionsCardiovascular autonomic neuropathy was associated with carotid atherosclerosis in Type 2 diabetic patients. Abnormal E/I ratios reflect efferent structural damage to parasympathetic nerves whereas abnormal AI reflects afferent autonomic dysfunction possibly due to impaired baroreceptor sensitivity secondary to carotid atherosclerosis.

  • Effects of body fatness and physical activity on cardiovascular risk: risk prediction using the bioelectrical impedance method.
  • 2006
  • Ingår i: Scandinavian Journal of Public Health. - : SAGE Publications. - 1651-1905 .- 1403-4948. ; 34:6, s. 568-575
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To explore the effects of body fat percentage (BF%) on incidence of and mortality from cardiovascular disease (CVD) and to study the cardio-protective effect of physical activity in relation to BF%. Methods: A total of 26,942 men and women, aged 45-73 years, without history of CVD were followed up for incidence of coronary events (CE), ischaemic stroke, and CVD mortality over seven years in relation to sex-specific quartiles (Q1-Q4) of BF%. The cardio-protective effect of leisure-time physical activity was studied in relation to BF%. Results: In men, the relative risk (RR) for CE and CVD mortality increased progressively with BF%. RR for CE in Q4 was 1.37 (95% confidence interval: 1.07-1.74), adjusted for age, height, smoking, high alcohol intake, and physical activity, compared with Q1. In women, BF% was significantly associated with incidence of CE and stroke. BF% was more strongly correlated to body mass index (BMI) (r=50.83) and waist circumference (r=0.76) in women than in men (r=0.59 and r=50.66, respectively). BF% was a stronger risk factor than BMI in women, and equally strong as waist circumference. A significant interaction (p=0.013 for incidence of CE, p=0.026 for ischaemic stroke) was found between BF% and sex. The raised cardiovascular risk was reduced by physical activity in subjects with high BF%. Conclusions: BF% is a risk factor for CE, ischaemic stroke, and CVD mortality. An interaction between BF% and sex suggests that BF% is a stronger CVD risk factor in women. The raised cardiovascular risk associated with high BF% is reduced by physical activity.

  • Immune responses against fibronectin modified by lipoprotein oxidation and their association with cardiovascular disease.
  • 2009

    • Abstract. Dunér P, To F, Alm R, Gonçalves I, Fredrikson GN, Hedblad B, Berglund G, Nilsson J, Bengtsson E (Malmö University Hospital, Lund University, Lund, Sweden). Immune responses against fibronectin modified by lipoprotein oxidation and their association with cardiovascular disease. J Intern Med 2009; doi: 10.1111/j.1365-2796.2008.02067.xObjectives. Accumulation and subsequent oxidation of LDL in the arterial wall are considered as key events in the development of atherosclerosis. We have investigated the possibility that LDL oxidation results in release of aldehydes that modify surrounding matrix proteins and that this may target immune responses against the plaque extracellular matrix and modulate the disease progression. Results. Using custom-made ELISAs we demonstrate that human plasma contains autoantibodies against aldehyde-modified fibronectin (FN) and to a lesser extent also other extracellular matrix proteins including collagen type I, type III, and tenascin-C. Immunohistochemistry and western blot analysis showed that aldehyde-modified FN is present in human atherosclerotic plaques and that aldehydes generated by oxidation of LDL formed adducts with FN in vitro. We also demonstrate that aldehyde-modification of FN results in a loss of its ability to promote basal secretion of cytokines and growth factors from cultured macrophages without affecting the ability of the cells to respond to stimulation with LPS. A prospective clinical study demonstrated that subjects that subsequently developed acute myocardial infarction or sudden cardiac death had lower baseline levels of autoantibodies against aldehyde-modified FN than matched controls. Conclusions. These observations demonstrate that oxidation of LDL in the arterial wall may lead to aldehyde-modification of surrounding extracellular matrix proteins and that these modifications may affect macrophage function and activate autoimmune responses of pathophysiological importance for the development of atherosclerosis.

  • Blood pressure increase and incidence of hypertension in relation to inflammation-sensitive plasma proteins.
  • 2002
  • Ingår i: Arteriosclerosis, Thrombosis and Vascular Biology. - 1524-4636. ; 22:12, s. 2054-2058

    • Objective— The reasons for the relationship between inflammation-sensitive plasma proteins (ISPs) and incidence of cardiovascular diseases are poorly understood. This study explored the hypothesis that ISPs are associated with future hypertension and age-related blood pressure increase. Method and Results— Blood pressure and plasma levels of fibrinogen, {alpha}1-antitrypsin, haptoglobin, ceruloplasmin, and orosomucoid were determined in 2262 healthy men aged 35 to 50 years, initially without treatment for hypertension. The cohort was re-examined after 15.7 (±2.2) years. Incidence of hypertension and blood pressure increase was studied in relation to number of elevated proteins (ie, in the top quartile) at baseline. Among men without treatment for hypertension at follow-up, mean (±SD) increase in systolic blood pressure was 18.8±17, 19.2±17, 19.3±17, and 22.1±18 mm Hg, respectively, for men with 0, 1, 2, and >=3 elevated proteins (P for trend=0.02, adjusted for confounders). The corresponding values for pulse pressure increase was 15.5±14, 15.8±14, 17.4±14, and 17.8±15 mm Hg, respectively (P=0.02). Incidence of hypertension (>=160/95 mm Hg or treatment) and future blood pressure treatment showed similar associations with ISPs. Increase in diastolic blood pressure showed no association with ISPs. Conclusions— Plasma levels of ISPs are associated with a future increase in blood pressure. This could contribute to the relationship between ISP levels and cardiovascular disease.

  • Distribution and determinants of ischaemic heart disease in an urban population. A study from the myocardial infarction register in Malmo, Sweden
  • 2000
  • Ingår i: Journal of Internal Medicine. - : Wiley. - 1365-2796 .- 0954-6820. ; 247:5, s. 588-596
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: Age adjusted incidence of myocardial infarction has been found to vary substantially between the residential areas of the city of Malmo. The objective of this study was to assess the extent to which major biological risk factors and socio-economic circumstances account for the differences in incidence of and mortality from myocardial infarction. DESIGN: Ecological study of risk factor prevalence and incidence and mortality from myocardial infarction. SETTING: Seventeen administrative areas in Malmo, Sweden. SUBJECTS: Assessment of risk factor prevalence was based on 28 466 men and women, ranging from 45 to 73 years old, who were recruited as participants in the Malmo Diet and Cancer study. Information on serum lipids was available in a random subsample of 5362 subjects. Information about socio-economic level of the residential area was based on statistics from the Malmo City Council and Statistics Sweden. MAIN OUTCOME MEASURES: Weighted least square regressions between prevalence of risk factors (i.e. smoking, hypertension, obesity, diabetes, hypercholesterolemia and hypertriglyceridemia), a myocardial infarction risk score, a socio-economic score and incidence and mortality from myocardial infarction. RESULTS: The risk factor prevalence and myocardial infarction incidence was highest in areas with low socio-economic level. Prevalence of smoking, obesity and hypertension was significantly associated with myocardial infarction incidence and mortality rates amongst men (all r > 0.60). Prevalence of smoking was significantly associated with incidence and mortality from myocardial infarction amongst women (r = 0.66 and r = 0.61, respectively). A myocardial infarction risk score based on four biological risk factors explained 40-60% of the intra-urban geographical variation in myocardial infarction incidence and mortality. The socio-economic score added a further 2-16% to the explained variance. CONCLUSION: In an urban population with similar access to medical care, well-known biological cardiovascular risk factors account for a substantial proportion of the intra-urban geographical variation of incidence of and mortality from myocardial infarction. The socio-economic circumstances further contribute to the intra-urban variation in disease.

  • Incidence of myocardial infarction in women. A cohort study of risk factors and modifiers of effect
  • 2000
  • Ingår i: Journal of Epidemiology and Community Health. - 1470-2738. ; 54:2, s. 104-107
  • Tidskriftsartikel (refereegranskat)abstract
    • STUDY OBJECTIVE: To assess whether the increased incidence of myocardial infarction and death associated with smoking, hypertension, hyperlipidaemia and diabetes varies significantly between groups defined in terms of occupation, education and marital status. SETTING: Malmo, Sweden. PARTICIPANTS: 9351 women, aged 28-55, with a mean follow up of 10.7 years. MAIN RESULTS: Smoking, hypertension (> or = 160/95 mm Hg or treatment), hyperlipidaemia (cholesterol > or = 6.5 mmol/l or triglycerides > or = 2.3 mmol/l), diabetes, low occupation and education levels were significantly more common among women who experienced a fatal or nonfatal myocardial infarction during the follow up (n = 104) than in other women (n = 9247). Exposure to smoking, hypertension and hyperlipidaemia showed substantial differences between groups defined in terms of education, occupation and marital status. The association between low occupation and myocardial infarction remained statistically significant after adjustments for several potential confounders (RR = 2.6, 95% CI 1.1, 6.0). Single women had similarly higher adjusted mortality rates than married women (RR = 1.4, 95% CI 1.1, 1.8). When other major risk factors were taken into account, the relative risk for mortality and myocardial infarction associated with smoking was 2.6 (95% CI 2.0, 3.4) and 7.8 (95% CI 4.4, 13.9), respectively. CONCLUSION: In this urban female population, short education and low occupation level were both associated with an increased prevalence of smoking, hypertension, hyperlipidaemia and diabetes. Low occupation level increases the rate of cardiac events caused by exposure to these four risk factors.

  • Lung function, insulin resistance and incidence of cardiovascular disease: a longitudinal cohort study.
  • 2003
  • Ingår i: Journal of Internal Medicine. - : Wiley. - 1365-2796 .- 0954-6820. ; 253:5, s. 574-581
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives. To explore whether a reduced lung function is a risk factor for developing diabetes and insulin resistance (IR), and whether such relationship contributes to the largely unexplained association between lung function and incidence of cardiovascular disease (CVD). Design. Forced vital capacity (FVC) was assessed at baseline. Incidence of diabetes and IR [according to the homeostasis model assessment (HOMA) model] was assessed in a follow-up examination after 13.9 ± 2.6 and 9.4 ± 3.6 years for men and women, respectively. After the follow-up examination, incidence of CVD (stroke, myocardial infarction or cardiovascular death) was monitored over 7 years. Setting. Populations-based cohort study. Subjects. Initially nondiabetic men (n = 1436, mean age 44.6 years) and women (n = 896, mean age 49.8 years). Results. Prevalence of IR at the follow-up examination was 34, 26, 21 and 21%, respectively, for men in the first (lowest), second, third and fourth quartile of baseline FVC (P for trend <0.0001). The corresponding values for women were 30, 29, 25 and 17%, respectively (P for trend <0.001). Adjusted for potential confounders, the odds ratio (OR) for IR (per 10% increase in FVC) was 0.91 (CI: 0.84-0.99) for men and 0.89 (CI: 0.80-0.98) for women. FVC was similarly significantly associated with the incidence of diabetes (OR = 0.90, CI: 0.81-1.00), adjusted for sex and other confounders. The incidence of CVD after the follow-up examination was significantly increased only amongst subjects with low FVC who had developed IR (RR = 1.7, CI: 1.02-2.7). Conclusion. Subjects with a moderately reduced FVC have an increased risk of developing IR and diabetes. This relationship seems to contribute to the largely unexplained association between reduced lung function and incidence of CVD.

  • Plasma levels of complement C3 is associated with development of hypertension: a longitudinal cohort study.
  • 2007
  • Ingår i: Journal of Human Hypertension. - : Springer Science and Business Media LLC. - 1476-5527 .- 0950-9240. ; 21, s. 276-282
  • Tidskriftsartikel (refereegranskat)abstract
    • Hypertension has been associated with raised plasma levels of complement factor 3 and 4 (C3 and C4). The nature of this association is unclear. This population-based longitudinal study explored whether C3 or C4 is associated with development of hypertension. Blood pressure and plasma levels of C3 and C4 were determined in 2178 healthy men, aged 35-50 years, initially without treatment for hypertension. Incidence of hypertension and blood pressure increase over 15.7 (+/- 2.2) years follow-up was studied in relation to C3 and C4 at baseline. Among men with initially normal blood pressure (<160/95 mm Hg), incidence of hypertension (>= 160/95 mm Hg or treatment) was 32, 42, 37 and 47%, respectively, for men with C3 in the first, second, third and fourth quartile (trend: P = 0.001). This relationship remained significant after adjustment for confounding factors. Among men without blood pressure treatment, systolic BP increase (mean + standard error, adjusted for age, initial blood pressure and follow-up time) was 17.5 + 0.8, 19.6 + 0.9, 19.8 + 0.8 and 20.8 + 0.8 mm Hg, respectively, in the C3 quartiles (trend: P = 0.004). C3 was not associated diastolic blood pressure at follow-up. Although C4 was associated with blood pressure at the baseline examination, there was no relationship between C4 and development of hypertension or future blood pressure increase. It is concluded that C3 in plasma is associated with future blood pressure increase and development of hypertension.
