- OBJECTIVE: In Sweden, previous favourable trends in blood cholesterol levels have recently levelled off or even increased in some age groups since 2003, potentially reflecting changing fashions and attitudes towards dietary saturated fatty acids (SFA). We aimed to examine the potential effect of different SFA intake on future coronary heart disease (CHD) mortality in 2025. METHODS: We compared the effect on future CHD mortality of two different scenarios for fat intake a) daily SFA intake decreasing to 10 energy percent (E%), and b) daily SFA intake rising to 20 E%. We assumed that there would be moderate improvements in smoking (5%), salt intake (1g/day) and physical inactivity (5% decrease) to continue recent, positive trends. RESULTS: In the baseline scenario which assumed that recent mortality declines continue, approximately 5,975 CHD deaths might occur in year 2025. Anticipated improvements in smoking, dietary salt intake and physical activity, would result in some 380 (-6.4%) fewer deaths (235 in men and 145 in women). In combination with a mean SFA daily intake of 10 E%, a total of 810 (-14%) fewer deaths would occur in 2025 (535 in men and 275 in women). If the overall consumption of SFA rose to 20 E%, the expected mortality decline would be wiped out and approximately 20 (0.3%) additional deaths might occur. CONCLUSION: CHD mortality may increase as a result of unfavourable trends in diets rich in saturated fats resulting in increases in blood cholesterol levels. These could cancel out the favourable trends in salt intake, smoking and physical activity.

Tidskriftsartikel (refereegranskat)abstract
- An evaluation of Vasterbotten Intervention Programme (VIP) was recently conducted by San Sebastian et al. (BMC Public Health 19:202, 2019). Evaluation of health care interventions of this kind require 1) an understanding of both the design and the nature of the intervention, 2) correct definition of the target population, and 3) careful choice of the appropriate evaluation method. In this correspondence, we review the approach used by San Sebastian et al. as relates to these three criteria. Within this framework, we suggest important explanations for why the conclusions drawn by these authors contradict a large body of research on the effectiveness of the VIP.

- OBJECTIVE: To evaluate the impact of the Västerbotten Intervention Programme (VIP) by comparing all eligible individuals (target group impact) according to the intention-to-treat principle and VIP participants with the general Swedish population.DESIGN: Dynamic cohort study.SETTING/PARTICIPANTS: All individuals aged 40, 50 or 60 years, residing in Västerbotten County, Sweden, between 1990 and 2006 (N=101 918) were followed from their first opportunity to participate in the VIP until age 75, study end point or prior death.INTERVENTION: The VIP is a systematic, long-term, county-wide cardiovascular disease (CVD) intervention that is performed within the primary healthcare setting and combines individual and population approaches. The core component is a health dialogue based on a physical examination and a comprehensive questionnaire at the ages of 40, 50 and 60 years.PRIMARY OUTCOMES: All-cause and CVD mortality.RESULTS: For the target group, there were 5646 deaths observed over 1 054 607 person-years. Compared to Sweden at large, the standardised all-cause mortality ratio was 90.6% (95% CI 88.2% to 93.0%): for women 87.9% (95% CI 84.1% to 91.7%) and for men 92.2% (95% CI 89.2% to 95.3%). For CVD, the ratio was 95.0% (95% CI 90.7% to 99.4%): for women 90.4% (95% CI 82.6% to 98.7%) and for men 96.8% (95% CI 91.7 to 102.0). For participants, subject to further impact as well as selection, when compared to Sweden at large, the standardised all-cause mortality ratio was 66.3% (95% CI 63.7% to 69.0%), whereas the CVD ratio was 68.9% (95% CI 64.2% to 73.9%). For the target group as well as for the participants, standardised mortality ratios for all-cause mortality were reduced within all educational strata.CONCLUSIONS: The study suggests that the VIP model of CVD prevention is able to impact on all-cause and cardiovascular mortality when evaluated according to the intention-to-treat principle.

- AIMS: To assess the prognostic importance of high-sensitive C reactive protein (hsCRP) in patients with mild to moderate aortic valve stenosis during placebo or simvastatin/ezetimibe treatment in Simvastatin and Ezetimibe in Aortic Stenosis (SEAS).METHODS AND RESULTS: In 1620 SEAS patients, we measured lipids and hsCRP at baseline and after 1 year of treatment and registered during 4 years of follow-up major cardiovascular events (MCE) composed of ischaemic cardiovascular events (ICE) and aortic valve-related events (AVE). Simvastatin/ezetimibe reduced low-density lipoprotein cholesterol (3.49 (2.94 to 4.15) to 1.32 (1.02 to 1.69) vs 3.46 (2.92 to 4.08) to 3.34 (2.81 to 3.92) mmol/L) and hsCRP (2.1 (0.9 to 4.1) to 1.2 (0.6 to 2.4) vs 2.2 (0.9 to 4.9) to 1.8 (0.85 to 4.35) mg/L, all p<0.05) during the first year of treatment. In multivariable Cox regression analysis adjusting for traditional risk factors and baseline hsCRP, ICE was associated with a 1-year increase of hsCRP (HR=1.19 (95% CI 1.12 to 1.25), p<0.001) but not with active treatment (HRTreatment=0.86 (0.67 to 1.13), p=0.28). Patients in the top quartile of baseline hsCRP versus the rest were associated with a higher risk of MCE (HR=1.34(1.09 to 1.64), p=0.02). The prognostic benefit of reduction in hsCRP after 1 year was significantly larger (p<0.01 for interaction) in patients with high versus low baseline hsCRP; hence, a reduction in hsCRP abolished the difference in incidence of MCE between high versus low baseline hsCRP in patients with reduced hsCRP (31.1 vs 31.9%, NS) in contrast to patients with increased hsCRP.CONCLUSIONS: The treatment-associated reduction in ICE was in part related to a reduction in hsCRP but not in lipids. hsCRP reduction was associated with less MCE, especially in patients with high baseline hsCRP.TRIAL REGISTRATION: NCT00092677.

- Objective To investigate relations between inflammation and aortic valve stenosis (AS) by measuring high-sensitivity C-reactive protein, at baseline (hsCRP(0)) and after 1year (hsCRP(1)) and exploring associations with aortic valve replacement (AVR). Design We examined 1423 patients from the Simvastatin and Ezetimibe in Aortic Stenosis study. Results During first year of treatment, hsCRP was reduced both in patients later receiving AVR (2.3 [0.9-4.9] to 1.8 [0.8-5.4] mg/l, p<0.001) and not receiving AVR (1.90 [0.90-4.10] to 1.3 [0.6-2.9] mg/l, p<0.001). In Cox-regression analyses, hsCRP(1) predicted later AVR (HR=1.17, p<0.001) independently of hsCRP(0) (HR=0.96, p=0.33), aortic valve area (AVA) and other risk factors. A higher rate of AVR was observed in the group with high hsCRP(0) and an increase during the first year (AVR(highCRP0CRP1inc)=47.3% versus AVR(highCRP0CRP1dec)=27.5%, p<0.01). The prognostic benefit of a 1-year reduction in hsCRP was larger in patients with high versus low hsCRP(0) eliminating the difference in incidence of AVR between high versus low hsCRP(0) (AVR(highCRP0CRP1dec)=27.5% versus AVR(lowCRP0CRP1dec)=25.8%, p=0.66) in patients with reduced hsCRP during the first year. Conclusions High hsCRP(1) or an increase in hsCRP during the first year of follow-up predicted later AVR independently of AVA, age, gender and other risk factors, although no significant improvement in C-statistics was observed.

- We conducted a pilot trial of a remote blood pressure (BP) monitoring system, in which subjects measured their own BP at a primary healthcare centre. The data were wirelessly transmitted to the general practitioner. A total of 132 subjects with a new or prior diagnosis of hypertension were enrolled. Their mean age was 61 years and 77 were men (58%). They were followed for an average of 487 days (range 19-1110). The median number of BP measurements made was 6 per patient (range 2-49). The mean blood pressure decreased from 137/85 to 132/78 mmHg (P < 0.001) and the percentage of subjects with adequately controlled BP (defined as < 140/90 mmHg) increased from 47 to 66% (P < 0.01). Randomised trials are now required to confirm these findings.

- Background: To explore the relationships between anaemia or iron deficiency (ID) and symptoms, quality of life (QoL), morbidity, and mortality.Methods: A post-hoc, non-prespecified, explorative substudy of the prospective randomized PREFER trial. One centre study of outpatients with severe HF and palliative need managed with advanced home care. Associations between anaemia, ID, and the Edmonton Symptom Assessment Scale (ESAS), Euro QoL (EQ-5D), Kansas City Cardiomyopathy Questions (KCCQ) were examined only at baseline but at 6months for morbidity and mortality.Results: Seventy-two patients (51 males, 21 females), aged 79.2±9.1years. Thirty-nine patients (54%) had anaemia and 34 had ID (47%). Anaemia was correlated to depression (r=0.37; p=0.001), anxiety (r=0.25; p=0.04), and reduced well-being (r=0.26; p=0.03) in the ESAS; mobility (r=0.33; p=0.005), pain/discomfort (r=0.27; p=0.02), and visual analogue scale of health state (r=-0.28; p=0.02) in the EQ-5D; and physical limitation (r=-0.27; p=0.02), symptom stability; (r=-0.43; p<0.001); (r=-0.25; p=0.033), social limitation;(r=-0.26; p=0.03), overall summary score; (r=-0.24, p=0.046) and clinical summary score; (r=-0.27; p=0.02) in the KCCQ. ID did not correlate to any assessment item. Anaemia was univariably associated with any hospitalization (OR: 3.0; CI: 1.05-8.50, p=0.04), but not to mortality. ID was not significantly associated with any hospitalization or mortality.Conclusion: Anaemia, but not ID, was associated although weakly with symptoms and QoL in patients with advanced HF and palliative home care.

- INTRODUCTION: In COMET (Carvedilol or Metoprolol European Trial), carvedilol reduced mortality compared with metoprolol in patients with chronic heart failure. We hypothesized that carvedilol might have greater effects on endothelial derived haemostatic factors than metoprolol. We aimed to study the effects of carvedilol or metoprolol on tissue plasminogen activator (tPA), its inhibitor PAI-1 and Von Willebrand factor (VWF) in patients with heart failure. MATERIAL AND METHODS: We recruited 260 patients (134 on carvedilol, 126 on metoprolol), mean age 66 years and 84% of them men. Plasma mass concentrations of tPA and PAI-1and percent of VWF were measured at baseline and after one and two years of treatment. RESULTS: Plasma tPA, PAI-1 and VWF were similar between treatment groups at baseline and no significant differences between groups emerged after one or two years of treatment. In paired analyses in patients assigned to carvedilol, median PAI-1 level decreased from 37.2 to 32.1 microg/l at two years (p=0.034) and of VWF decreased from baseline to one year (240 vs. 218%, p=0.023) in patients assigned to carvedilol but were not reduced at any time in patients assigned to metoprolol. Plasma tPA increased over time in both treatment groups (p=0.013 and 0.027 respectively). CONCLUSION: We found no significant difference in the effects of carvedilol or metoprolol on tPA, PAI-1 and VWF. Comparison over time within treatment groups suggested that PAI-1 and VWF might have declined on carvedilol but not on metoprolol. Our hypothesis is not proved but this may reflect an inadequate sample size rather than lack of an effect.

- 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.
