  • Smokeless tobacco (snus) and risk of heart failure : results from two Swedish cohorts
  • 2012
  • Ingår i: European Journal of Cardiovascular Prevention & Rehabilitation. - : Sage Publications. - 1741-8267 .- 1741-8275. ; 19:5, s. 1120-1127

    • Background: Oral moist snuff (snus) is discussed as a safer alternative to smoking, and its use is increasing. Based on its documented effect on blood pressure, we hypothesized that use of snus increases the risk of heart failure.Design: Two independent Swedish prospective cohorts; the Uppsala Longitudinal Study of Adult Men (ULSAM), a community-based sample of 1076 elderly men, and the Construction Workers Cohort (CWC), a sample of 118,425 never-smoking male construction workers. Methods: Cox proportional hazards models were used to investigate possible associations of snus use with risk of a first hospitalization for heart failure.Results: In ULSAM, 95 men were hospitalized for heart failure, during a median follow up of 8.9 years. In a model adjusted for established risk factors including past and present smoking exposure, current snus use was associated with a higher risk of heart failure [hazard ratio (HR) 2.08, 95% confidence interval (CI) 1.03-4.22] relative to non-use. Snus use was particularly associated with risk of non-ischaemic heart failure (HR 2.55, 95% CI 1.12-5.82). In CWC, 545 men were hospitalized for heart failure, during a median follow up of 18 years. In multivariable-adjusted models, current snus use was moderately associated with a higher risk of heart failure (HR 1.28, 95% CI 1.00-1.64) and non-ischaemic heart failure (HR 1.28, 95% CI 0.97-1.68) relative to never tobacco use.Conclusion: Data from two independent cohorts suggest that use of snus may be associated with a higher risk of heart failure.

  • Collaborative meta-analysis of individual participant data from observational studies of Lp-PLA2 and cardiovascular diseases
  • 2007
  • Ingår i: European Journal of Cardiovascular Prevention & Rehabilitation. - : Oxford University Press. - 1741-8267 .- 1741-8275. ; 14:1, s. 3-11
  • Forskningsöversikt (refereegranskat)abstract
    • BACKGROUND: A large number of observational epidemiological studies have reported generally positive associations between circulating mass and activity levels of lipoprotein-associated phospholipase A2 (Lp-PLA2) and the risk of cardiovascular diseases. Few studies have been large enough to provide reliable estimates in different circumstances, such as in different subgroups (e.g., by age group, sex, or smoking status) or at different Lp-PLA2 levels. Moreover, most published studies have related disease risk only to baseline values of Lp-PLA2 markers (which can lead to substantial underestimation of any risk relationships because of within-person variability over time) and have used different approaches to adjustment for possible confounding factors. OBJECTIVES: By combination of data from individual participants from all relevant observational studies in a systematic 'meta-analysis', with correction for regression dilution (using available data on serial measurements of Lp-PLA2), the Lp-PLA2 Studies Collaboration will aim to characterize more precisely than has previously been possible the strength and shape of the age and sex-specific associations of plasma Lp-PLA2 with coronary heart disease (and, where data are sufficient, with other vascular diseases, such as ischaemic stroke). It will also help to determine to what extent such associations are independent of possible confounding factors and to explore potential sources of heterogeneity among studies, such as those related to assay methods and study design. It is anticipated that the present collaboration will serve as a framework to investigate related questions on Lp-PLA2 and cardiovascular outcomes. METHODS: A central database is being established containing data on circulating Lp-PLA2 values, sex and other potential confounding factors, age at baseline Lp-PLA2 measurement, age at event or at last follow-up, major vascular morbidity and cause-specific mortality. Information about any repeat measurements of Lp-PLA2 and potential confounding factors has been sought to allow adjustment for possible confounding and correction for regression dilution. The analyses will involve age-specific regression models. Synthesis of the available observational studies of Lp-PLA2 will yield information on a total of about 15 000 cardiovascular disease endpoints.

  • Exercise and cardiovascular outcomes in hypertensive patients in relation to structure and function of left ventricular hypertrophy : the LIFE study.
  • 2009
  • Ingår i: European Journal of Cardiovascular Prevention & Rehabilitation. - 1741-8267 .- 1741-8275. ; 16:2, s. 242-248
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Exercise lowers blood pressure and improves cardiovascular function, but little is known about whether exercise impacts cardiovascular morbidity and mortality independent of left ventricular hypertrophy (LVH) and LV geometry. DESIGN: Observational analysis of prospectively obtained echocardiographic data within the context of a randomized trial of antihypertensive treatment. METHODS: A total of 937 hypertensive patients with ECG LVH were studied by echocardiography in the Losartan Intervention For Endpoint reduction in hypertension study. Baseline exercise status was categorized as sedentary (never exercise), intermediate (30 min twice/week). During 4.8-year follow-up, 105 patients suffered the primary composite endpoint of myocardial infarction (MI), stroke, or cardiovascular death. MI occurred in 39, stroke in 60, and cardiovascular death in 33 patients. RESULTS: Sedentary individuals (n = 212) had, compared with those physically active (n = 511), higher heart rate (P<0.001), weight (P<0.001), body surface area (P = 0.02), body mass index (P<0.001), LV mass (LVM, P = 0.04), LVM indexed for height or body surface area (P = 0.004); thicker ventricular septum (P = 0.012) and posterior wall (P = 0.016); and larger left atrium (P = 0.006). Systolic variables did not differ. In Cox regression analysis, physically active compared with sedentary patients had lower risk of primary composite endpoint [odds ratio (OR): 0.42, 95% confidence interval (CI): 0.26-0.68, P < 0.001], cardiovascular death (OR: 0.50, 95% CI: 0.22-0.1.10, NS), and stroke (OR: 0.26, 95% CI: 0.13-0.49, P < 0.001) without significant difference for MI (OR: 0.79, 95% CI: 0.35-1.75, NS) independent of systolic blood pressure, LVM index, or treatment. CONCLUSION: In hypertensive patients with LVH, physically active patients had improved prognosis for cardiovascular endpoints, mortality, and stroke that was independent of LVM.

  • Coronary flow velocity reserve reduction is comparable in patients with erectile dysfunction and in patients with impaired fasting glucose or well-regulated diabetes mellitus
  • 2007
  • Ingår i: European Journal of Cardiovascular Prevention & Rehabilitation. - : Lippincott Williams & Wilkins. - 1741-8275. ; 14:2, s. 258-264
  • Tidskriftsartikel (refereegranskat)abstract
    • Background There is growing evidence that erectile dysfunction is a sentinel for future coronary artery disease. Recently published studies have shown signs of impaired coronary endothelial function in patients with erectile dysfunction, without clinical cardiovascular disease and diabetes. We evaluated the magnitude of coronary vasodilatory dysfunction in men with erectile dysfunction, as compared with men with impaired glucose metabolism (impaired fasting glucose or diabetes) and healthy controls. Methods We investigated men aged 68-73 years with erectile dysfunction (n=12), age-matched men with impaired glucose metabolism, who all proved to have erectile dysfunction (n=15), and age-matched male controls (n=12). Erectile dysfunction was evaluated using the International Index of Erectile Function (IIEF)-5 questionnaire. Coronary flow velocity reserve in the left anterior descending artery was examined using Doppler ultrasound and intravenous adenosine provocation. Results Coronary flow velocities at rest did not differ between the three groups, but maximum coronary flow velocity was significantly lower in the erectile dysfunction group (P= 0.004) and in the impaired glucose metabolism group (P= 0.019), as compared with controls. There was no difference between the erectile dysfunction and impaired glucose metabolism groups. Coronary flow velocity reserve was reduced in the erectile dysfunction group (P=0.026) compared to controls, but was similar compared to the impaired glucose metabolism group. In multivariate analysis including all groups, erectile dysfunction score was the only independent predictor of reduced coronary flow velocity reserve (P=0.020). Conclusions The magnitude of early coronary endothelial and smooth muscle cell dysfunction in otherwise healthy men with erectile dysfunction was comparable to that of patients with impaired glucose metabolism: a well known risk factor for coronary artery disease.

  • Independent associations of physical activity and cardiovascular fitness with cardiovascular risk in adults.
  • 2010
  • Ingår i: European Journal of Cardiovascular Prevention & Rehabilitation. - 1741-8267 .- 1741-8275. ; 17:2, s. 175-80
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Uncertainty still exists whether physical activity (PA) and cardiovascular fitness (CF) contribute separately to cardiovascular disease (CVD) risk. This study examined the associations of PA and CF on individual as well as clustered CVD risk factors. DESIGN: Cross-sectional. METHODS: Seven hundred and eighty-one men and 890 women, aged 20-65 years, from two random population-based samples of Swedish women and men were included. PA was assessed by questionnaire and CF was predicted by a submaximal cycle ergometry test. Waist circumference, blood pressure, and fasting levels of blood lipids were assessed and dichotomized by conventional cut-off points. RESULTS: Participants reporting high PA level benefited from lower triglycerides and atherogenic cholesterol levels, regardless of CF. Higher CF level was, regardless of PA, associated with lower risk for all risk factors. With regard to clustering of risk factors, each higher CF level was associated with a gradually reduced risk by half or more, independent of PA. Furthermore, being unfit but reporting high PA was associated with a 50% lower risk compared with being unfit and inactive. Furthermore, high reported PA was associated with an additional reduced risk among fit participants. In addition, an excess risk of interaction was found for waist circumference, triglycerides, and the clustered CVD risk between neither being sufficiently active nor being fit. CONCLUSION: This study suggests that both PA and CF are independently associated with lower cardiovascular risk, and that both variables should be taken into account when CVD risk is estimated.

  • Blood lipids in 75,048 type 2 diabetic patients: a population-based survey from the Swedish National diabetes register.
  • 2011
  • Ingår i: European journal of cardiovascular prevention and rehabilitation : official journal of the European Society of Cardiology, Working Groups on Epidemiology & Prevention and Cardiac Rehabilitation and Exercise Physiology. - : Lippincott Williams & Wilkins. - 1741-8275 .- 1741-8267. ; 18:1, s. 97-105
  • Tidskriftsartikel (refereegranskat)abstract
    • Type 2 diabetes and diabetic dyslipidemia are high-risk conditions for cardiovascular disease. However, the description of the distribution of blood lipids in diabetic patients has not been based on population-based surveys. The aim of this study was to describe diabetic dyslipidemia in a large unselected sample of patients from the Swedish National Diabetes Register.

  • Trends in incidence and outcome of out-of-hospital cardiac arrest among people with validated myocardial infarction
  • 2013
  • Ingår i: European Journal of Cardiovascular Prevention & Rehabilitation. - London, England : Sage Publications. - 1741-8267 .- 1741-8275. ; 20:2, s. 260-267
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To describe trends in incidence, outcome, and background characteristics among people who suffered an out-of-hospital cardiac arrest with validated myocardial infarction aetiology (OHCA-V).Methods and results: People from the northern Sweden MONICA myocardial registry (1989-2007) with OHCA-V (n = 2977) were divided in two age groups (25-64 and 65-74 years). Both those who were resuscitated outside hospital and those who died before resuscitation was started were included in the study. The younger age group was studied during 1989-2007 and the older group during 2000-2007. The incidence of OHCA-V decreased in both the younger group (men p < 0.0001, women p = 0.04) and the older group (men p < 0.0001, women p < 0.0007, respectively). The proportion with a history of ischaemic heart disease prior to the event decreased (p < 0.0001). The proportion of previous myocardial infarction decreased (p < 0.0001), diabetes mellitus increased (p = 0.001), coronary interventions increased (p < 0.0001), and survival after OHCA-V increased (p < 0.0001) in the younger group but not in the older group. Long-term survival after OHCA-V was better in the younger than in the older group (p = 0.026).Conclusion: The incidence of OHCA-V decreased in both sexes. The proportion surviving after OHCA-V was small but increased, and long-term survival (≥28 days) was better in the younger age group. Primary preventive measures may explain most of the improvements. However, the effects of secondary preventive measures cannot be excluded.
