- Objectives. To explore nation-wide use of anticoagulation in stroke patients with atrial fibrillation, in routine clinical practice in Sweden.Design. Cross-sectional cohort study.Setting. Patients included in Riks-Stroke, the Swedish national quality register for stroke care, during 2001.Subjects. Hospitals with incomplete coverage were excluded, leaving 4538 stroke patients with atrial fibrillation amongst 18 276 stroke patients from 75 hospitals in six health care regions.Main outcome measure. Treatment with oral anticoagulants.Results. At stroke onset, the proportion of patients with atrial fibrillation and first-ever stroke, receiving oral anticoagulants as primary prevention was 11.0% (range 8.4–13.5% between regions and 2.5–24.4% between hospitals). Younger age, male sex and diabetes at stroke onset independently predicted primary prevention with oral anticoagulants. The proportion of stroke patients with atrial fibrillation receiving oral anticoagulants as secondary prevention at discharge was 33.5% (range 29.9–40.6% between regions and 16.4–61.9% between hospitals). Independent predictors for secondary prevention were younger age, male sex and independent activities of daily life (ADL) function before the stroke, being discharged to home, being fully conscious on admission and health care region.Conclusion. There were variations between hospitals and regions that differences in age, sex, functional impairments and comorbidities could not fully explain. This indicates that evidence-based primary and secondary prevention of embolic stroke is insufficiently practised. Local factors seem to determine whether patients with atrial fibrillation gain access to optimal prevention of stroke or not.

- Objectives. Low heart rate variability (HRV) is associated with poor prognosis after acute coronary events in men. In women, the prognostic impact is not well documented. The objective of this study was to assess the long-term predictive power of HRV on mortality amongst middle-aged women with coronary heart disease (CHD). Design, Settings and Subjects. Consecutive women below 65 years hospitalized for an acute coronary syndrome during a 3-year period in Stockholm were examined for cardiovascular prognostic factors including HRV, and followed for a median of 9 years. An ambulatory 24-h electrocardiograph was recorded during normal activities, 3-6 months after hospitalization. SDNN index (mean of the standard deviations of all normal to normal intervals for all 5-min segments of the entire recording) and the following frequency domain parameters were assessed: total power, high-frequency (HF) power, low-frequency (LF) power, very-low frequency (VLF) power and LF/HF ratio. Using Cox proportional hazards regression, the hazard ratios (HR) for each 25% decrease of the HRV parameters were assessed. Results. After controlling for the independent, significant predictors of mortality amongst the clinical variables, the following HRV parameters were found to be significant predictors of all-cause mortality: SDNN index [HR 1.56, 95% confidence intervals (CI) 1.19-2.05], total power (HR 1.21, 95% CI 1.08-1.35), VLF power (HR 1.22, 95% CI 1.09-1.36), LF power (HR 1.18 95%, CI 1.07-1.30) and HF power (HR 1.18, 95% CI 1.05-1.33). The results were essentially the same when cardiovascular mortality was used as end-points. The HRV parameters were stronger predictors of mortality in the first 5 years following the index event. Conclusion. Low HRV is a predictor of long-term mortality amongst middle-aged women with CHD when measured 3-6 months after hospitalization for an acute coronary syndrome, even after controlling for established clinical prognostic markers.

Tidskriftsartikel (refereegranskat)abstract
- In 787 patients with acute myocardial infarction originally participating in the Göteborg Metoprolol Trial, mortality and morbidity during 5 years' follow-up were assessed and related to whether patients had diabetes mellitus. Diabetes occurred in 78 patients (10%). Patients with diabetes had a different risk factor pattern, including higher age, higher occurrence of angina pectoris and hypertension, whereas smoking habits did not differ. In the early phase (hospitalization), patients with diabetes had a higher mortality (12% versus 8%), required more treatment for heart failure and stayed longer in hospital. Other morbidity aspects, such as severity of pain, occurrence of severe supraventricular and ventricular arrhythmias, high-degree AV-block and infarct size did not differ. During 5 years' follow-up mortality rate in patients with diabetes mellitus was 55% as compared with 30% among patients with no diabetes (P<0.001). Reinfarction rate during 5 years was 42% in daibetics versus 25% in non-diabetics (P<0.001). In a multivariate analysis, taking into account the differences in risk factor pattern, diabetes turned out to be an independent determinant for long-term mortality and reinfarction (P<0.001). We conclude that patients with diabetes mellitus, developing acute myocardial infarction, is a group with particularly high risk of death and reinfarction. Interventions aiming at its reduction have priority.

Tidskriftsartikel (refereegranskat)abstract
- The regression of the ECG signs of myocardial infarction has been studied in 101 patients. A significant increase in R wave amplitude and decrease in Q wave depth on the standard ECG was observed over three months. In 21% of the patients, Q waves disappeared completely. In inferior infarction, these changes were more apparent in the lateral V leads than in the inferior limb leads. Patients with intraventricular conduction defects were excluded. Two factors associated with the Q and R wave changes have been identified. Lower heart rates appeared to facilitate the recovery of R waves, and smaller infarcts, as assessed by peak LDH, showed greater ECG recovery. This study raises the interesting possibility that modification of the heart rate may affect favourably the healing process after an acute myocardial infarction.

Tidskriftsartikel (refereegranskat)abstract
- Inflammatory diseases and inflammatory markers secreted by the liver, including C-reactive protein (CRP) and ceruloplasmin, have been associated with incident atrial fibrillation (AF). Genetic studies have not supported a causal relationship between CRP and AF, but the relationship between ceruloplasmin and AF has not been studied. The purpose of this Mendelian randomization study was to explore whether genetic polymorphisms in the gene encoding ceruloplasmin are associated with elevated ceruloplasmin levels, and whether such genetic polymorphisms are also associated with the incidence of AF.

Tidskriftsartikel (refereegranskat)abstract
- Red blood cell distribution width (RDW), a measure of variation in erythrocyte volume, has been associated with several cardiovascular disorders, but the relationship with atrial fibrillation (AF) remains unclear. We investigated the association between RDW and incidence of first hospitalization due to AF in a population-based cohort.

- RDW is a new and easily available risk marker for adverse cardiovascular outcomes and we agree that this may encourage a wider use in clinical practice. As pointed out by Balta et al [2], the underlying causal links are unclear. The causal links could hypothetically involve some of the factors mentioned by Balta et al [2], but also properties of the red cells per se. This article is protected by copyright.

Tidskriftsartikel (refereegranskat)abstract
- Objective. The aim of this study was to investigate the effects of a healthy Nordic diet (ND) on cardiovascular risk factors. Design and subjects. In a randomized controlled trial (NORDIET) conducted in Sweden, 88 mildly hypercholesterolaemic subjects were randomly assigned to an ad libitum ND or control diet (subjects' usual Western diet) for 6 weeks. Participants in the ND group were provided with all meals and foods. Primary outcome measurements were low-density lipoprotein (LDL) cholesterol, and secondary outcomes were blood pressure (BP) and insulin sensitivity (fasting insulin and homeostatic model assessment-insulin resistance). The ND was rich in high-fibre plant foods, fruits, berries, vegetables, whole grains, rapeseed oil, nuts, fish and low-fat milk products, but low in salt, added sugars and saturated fats. Results. The ND contained 27%, 52%, 19% and 2% of energy from fat, carbohydrate, protein and alcohol, respectively. In total, 86 of 88 subjects randomly assigned to diet completed the study. Compared with controls, there was a decrease in plasma cholesterol (-16%, P < 0.001), LDL cholesterol (-21%, P < 0.001), high-density lipoprotein (HDL) cholesterol (-5%, P < 0.01), LDL/HDL (-14%, P < 0.01) and apolipoprotein (apo)B/apoA1 (-1%, P < 0.05) in the ND group. The ND reduced insulin (-9%, P = 0.01) and systolic BP by -6.6 +/- 13.2 mmHg (-5%, P < 0.05) compared with the control diet. Despite the ad libitum nature of the ND, body weight decreased after 6 weeks in the ND compared with the control group (-4%, P < 0.001). After adjustment for weight change, the significant differences between groups remained for blood lipids, but not for insulin sensitivity or BP. There were no significant differences in diastolic BP or triglyceride or glucose concentrations. Conclusions. A healthy ND improves blood lipid profile and insulin sensitivity and lowers blood pressure at clinically relevant levels in hypercholesterolaemic subjects.

Glucose levels and insulin secretion during a 75 g glucose challenge test in normal pregnancy
- 1996

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: The aim of the study was to evaluate glucose levels and insulin secretion early in pregnancy and at a time when gestational diabetes mellitus frequently occurs in order to define reference values for glucose tolerance during pregnancy. The results were also related to maternal factors that might identify subjects at risk of developing gestational diabetes mellitus as well as foetal factors that might be a result of impaired glucose tolerance during pregnancy. DESIGN: A prospective study. SETTING: All Caucasian women attending one antenatal out-patient care unit were offered a 75 g oral glucose tolerance test at the 17th and 32nd week of gestation. SUBJECTS: A total of 586 consecutive pregnant women were included in the study. All 586 women were examined by repeated blood glucose measurements and 298 agreed to perform oral glucose tolerance tests as well. MAIN OUTCOME MEASURES: Venous whole blood glucose values were measured in the fasting state and in samples obtained 15, 30, 45, 60, 75, 90 and 120 min after oral intake of 75 g glucose. Serum insulin and C-peptide were also measured at these times. In all subjects, a random blood glucose sample was taken at the first visit, and thereafter at the 20th, 30th and 36th week of gestation. Information was also obtained from all subjects regarding body mass index, weight gain during pregnancy, smoking habits, family history of diabetes and hypertension, hypertension during pregnancy, past obstetric history, parity, and fetal outcome. RESULTS: The glucose tolerance was significantly impaired at the 32nd week of gestation compared with the 17th week of gestation. The mean +2SD 2 h glucose value during the oral glucose tolerance test at the 32nd week of gestation was 8.0 mmol L-1. Impaired glucose tolerance was characterised by increased insulin resistance, with a significant rise in serum insulin and C-peptide concentrations and in the insulin/glucose index during the oral glucose tolerance test at the 32nd week of gestation. Maternal factors associated with an impaired glucose tolerance were a family history of diabetes mellitus, smoking, a weight gain more than 18 kg during pregnancy, and glucosuria, while a family history of hypertension and hypertension present during pregnancy were not. Foetal factors that might be a result of impaired glucose tolerance during pregnancy, e.g. macrosomia and prematurity as well as complicated deliveries such as vacuum extraction/forceps or Caesarean section, all tended to be associated with higher blood glucose values. The same pattern was seen when the Apgar score was < 7. CONCLUSIONS: The results from this study show that the present cut-off values for diagnosis of gestational diabetes mellitus should be revised. Even if some maternal factors might indicate an increased risk for impaired glucose tolerance during pregnancy, they are probably not enough to detect women with gestational diabetes mellitus. Therefore, a screening programme for gestational diabetes should be considered.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: The objective was to analyse whether a favourable change in risk factors, caused by a comprehensive risk factor modification programme, affected intima-media thickness (IMT) in the common carotid artery, and whether any such change was associated with a change in cardiovascular events during a 6-year follow-up. DESIGN: Patients were randomized 1 : 1 to special intervention or usual care. SETTING: Hypertension Unit at university hospital. SUBJECTS: A total of 164 patients were randomized. Inclusion criteria were male, aged 50-72 years (at randomization) and one or more of the following: Serum cholesterol level > 6.5 mmol L(-1), smoking or diabetes mellitus. All patients were prescribed antihypertensive treatment since many years. In 142 men good quality ultrasound recording of the common carotid IMT were achieved at baseline, 119 were re-examined after 3.3 years, and 97 patients were available for examination after mean follow-up time of 6.2 years. Cardiovascular events were available for all randomized patients. INTERVENTIONS: The nonpharmacological special intervention programme was based on one information meeting followed by five weekly 2-h sessions with participation of patients and spouses. The diet recommendations were similar to established guidelines. Overweight patients were instructed to lose weight, and diabetic patients were systematically taught self-monitoring of blood glucose. Smokers were invited to a smoking cessation programme with five weekly meetings. Follow-up visits were thereafter scheduled every 6 months. Lipid lowering drugs were recommended in the intervention group if the treatment goals using nonpharmacological measures were not achieved. Patients in the usual care group were told to quit smoking and to lower their consumption of fat and glucose. Antihypertensive treatment (i.e., selection of drugs) was on purpose kept similar in the two groups. MAIN OUTCOME MEASURES: The IMT of the common carotid artery as measured by ultrasound. Cardiovascular events during follow-up. RESULTS: Significant net reductions were seen for serum cholesterol, triglycerides, fasting glucose and smoking. No difference in change in IMT was observed during follow-up between the two randomization groups. The explanation was that patients with positive plaque status at baseline had a much larger increase in IMT over time than patients with negative plaque status, and that patients with positive plaque status more often survived and were available for re-examination after 6 years in the intervention group than in the usual care group. Total mortality was lower in the intervention group, compared with the usual care group, 13 and 29%, respectively (P=0.028). CONCLUSIONS: In high risk populations, long-term studies with surrogate endpoints may be misleading because of missing data in patients where a large increase in IMT would have been observed, had they been re-examined. Another important conclusion from our study was that the gloomy prognosis for this patient category may be improved by a dedicated risk factor intervention programme. The improved prognosis was observed mainly in those patients at highest risk judged from history of cardiovascular disease or positive ultrasound plaque status at baseline.

Tidskriftsartikel (refereegranskat)abstract
- Background: Previous studies have reported an increased fracture risk after bariatric surgery. Objective: To investigate the association between different bariatric surgery procedures and fracture risk. Methods: Incidence rates and hazard ratios for fracture events were analysed in the Swedish Obese Subjects study; an ongoing, nonrandomized, prospective, controlled intervention study. Hazard ratios were adjusted for risk factors for osteoporosis and year of inclusion. Information on fracture events were captured from the Swedish National Patient Register. The current analysis includes 2007 patients treated with bariatric surgery (13.3% gastric bypass, 18.7% gastric banding, and 68.0% vertical banded gastroplasty) and 2040 control patients with obesity matched on group level based on 18 variables. Median follow-up was between 15.1 and 17.9 years for the different treatment groups. Results: During follow-up, the highest incidence rate for first-time fracture was observed in the gastric bypass group (22.9 per 1000 person-years). The corresponding incidence rates were 10.4, 10.7 and 9.3 per 1000 person-years for the vertical banded gastroplasty, gastric banding and control groups, respectively. The risk of fracture was increased in the gastric bypass group compared with the control group (adjusted hazard ratio [adjHR] 2.58; 95% confidence interval [CI] 2.02–3.31; P < 0.001), the gastric banding group (adjHR 1.99; 95%CI 1.41–2.82; P < 0.001), and the vertical banded gastroplasty group (adjHR 2.15; 95% CI 1.66–2.79; P < 0.001). Conclusions: The risk of fracture is increased after gastric bypass surgery. Our findings highlight the need for long-term follow-up of bone health for patients undergoing this treatment.
