- OBJECTIVE: To determine whether men with possible angina (from their responses to the World Health Organization angina questionnaire) but a normal exercise ECG differ in long term rates of coronary heart disease events from men with no symptoms of angina. DESIGN: During 1972-75, 2014 apparently healthy men aged 40-59 years underwent an examination programme including case history, clinical examination, exercise ECG to exhaustion, and various other tests. All men completed the WHO angina questionnaire. SUBJECTS: Of 2014 men, 68 had possible angina, 1831 had no symptoms of angina, and 115 were excluded because they had definite angina or pathological exercise ECGs. All 68+1831 had normal exercise ECGs and none developed chest pain during the exercise test. RESULTS: At 26 years, men with possible angina had a coronary heart disease mortality of 25.0% (17/68) v 13.8% (252/1831) among men with no symptoms of angina (p < 0.013). They also had a higher incidence of coronary artery bypass grafting (CABG) (p < 0.0004) and acute myocardial infarction (p < 0.026). The excess coronary heart disease mortality among men with possible angina only started after 15 years, whereas differences in CABG/acute myocardial infarction started early. Multivariate analysis including well recognised coronary heart disease risk factors showed that possible angina was an independent risk factor (relative risk 1.79, 95% confidence interval 1.26 to 2.10). CONCLUSIONS: Men with possible angina, even with a normal exercise test, have a greater risk of dying from coronary heart disease, having an acute myocardial infarct, or needing a CABG than age matched counterparts with no symptoms of angina.

- BACKGROUND: Previous studies have shown that ST depressions > or =1.0 mm during or post-exercise increase long-term risk of dying from coronary heart disease (CHD), the need for coronary artery bypass grafting (CABG) or the development of acute myocardial infarction (AMI) in healthy men. In the present prospective cohort study we investigate whether less marked ST depressions may influence CHD mortality, incidence of AMI, the need for a CABG or having a non-fatal stroke. METHODS: During 1972-75, 2014 men aged 40-59 years, free from somatic diseases and not using any drugs, underwent an examination programme including case history, clinical examination, various blood tests and a symptom-limited exercise ECG-test. ECG was registered during exercise and at 30 s, 1, 2, 3 and 5 min post-exercise. The possible prognostic impact of ST-changes of 0.50-0.99 mm and > or =1.00 mm compared with normal ST-segments were studied separately and combined. Horizontal, down-sloping and slowly up-sloping ST-segment patterns were combined. RESULTS: After adjustment for age, smoking, blood pressure, cholesterol, maximal heart rate, left ventricular hypertrophy and physical fitness ST depressions > or =0.50 mm--during and/or post-exercise--were associated with a 1.47-fold [95% confidence interval (CI) 1.10-1.95], and 1.54-fold (95% CI of 1.17-2.04) increased 26 years risk of CHD-mortality, respectively. The same ST-changes also increased 22 years risk of developing non-fatal AMI or needing CABG but not developing non-fatal stroke. CONCLUSIONS: Even an ST depression > or =0.50 mm during and/or after exercise increases the long-term risk of CHD-death, developing an AMI or needing CABG. No association was found between ST-changes and incidence of non-fatal strokes.

Tidskriftsartikel (refereegranskat)abstract
- AIM: It has recently been suggested that exercise testing may be more valuable prognostically than it is diagnostically in apparently healthy subjects. We wanted to compare the accuracy of CHD risk assessment based on classical risk factors with an assessment also based on multiple exercise test parameters. METHODS AND RESULTS: In 1972-75, 2014 apparently healthy men aged 40-60 had a symptom limited exercise test during a cardiovascular survey. Three hundred died from CHD during 26 years of follow-up. Compared to Cox regression models solely including classical risk factors (CRF), models also including multiple exercise test parameters (CRF+X) were clearly superior (P < 0.0001). Risk scores were computed based on the models. CRF and CRF+X risk scores often differed markedly; CRF+X scores were generally most reliable in both the high and low risk range. In smokers with cholesterol >6.5 mmol/l (n = 470), the CRF and CRF+X models identified 67 vs. 110 men at the highest CHD risk level according to European guidelines (34.2% vs. 38.2% CHD mortality). Three in five CRF+X-identified smokers with cholesterol >6.5 mmol/l had CHD mortality similar to the mean of all 2014 men. CONCLUSION: Integration of multiple exercise test parameters and conventional risk factors improved CHD risk assessment substantially--especially in smokers with high cholesterol.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: We evaluated mortality from cardiovascular disease (CVD), coronary heart disease (CHD) and all causes in relation to use of any hormone therapy (HT) and HT with oestradiol and norethisterone or levonorgestrel. DESIGN: Population-based cohort study. SETTING AND SUBJECTS: Women in three Norwegian counties were invited to a health survey in 1985-88 and 82.8% participated. In all 14 324 post- or perimenopausal women aged 35-62 years, including 702 HT users with a mean age of 48.8 years, were followed for 14 years. RESULTS: Women using HT had mortality from all causes and CVD comparable with that of nonusers. The relative risk (RRs) for CVD mortality amongst all women were 0.69 (95% CI: 0.35-1.33) for users of HT, and 0.96 (95% CI: 0.43-2.17) for users of HT with norethisterone or levonorgestrel. Amongst women free of self-reported cardiovascular health problems at baseline all-cause, CVD and CHD mortality tended to be lower amongst users of HT whilst HT use was linked with increased mortality amongst women with cardiovascular health problems. CONCLUSIONS: In this cohort of women around the usual age of menopause all-cause or CVD mortality amongst users of HT, most often oestradiol combined with norethisterone or levonorgestrel, was not markedly different from that of nonusers. Early CHD events amongst HT users prior to the baseline survey, together with selective inclusion of healthy subjects, may in part explain protective effects of HT on CHD reported from previous observational studies.

- Pulsed tissue Doppler can measure myocardial velocities with high temporal resolution. Our aim was to determine the onset timing of the regional left ventricular longitudinal early lengthening (e) in relation to the mitral inflow (E) in acute coronary syndromes. We applied pulsed tissue Doppler to the septal, lateral, inferior, and anterior left ventricular basal walls of 160 patients with acute coronary syndromes and 60 control subjects. Maximum systolic and early diastolic velocities were lower for patient than for control walls (6.1 +/- 1.7 vs 7.9 +/- 1.4 cm/s, P <.0001, and 6.9 +/- 2.3 vs 10.0 +/- 2.3 cm/s, P <.0001, respectively) and e started later than E (12 +/- 30 vs 2 +/- 19 milliseconds later, P <.0001). All 3 variables related to the degree of visual left ventricular wall pathology. The intraindividual time range for all 4 e starts was wider for patients (43 +/- 27 vs 30 +/- 18 milliseconds, P <.0001). Our results show that pulsed tissue Doppler can identify a delayed and asynchronous initial wall lengthening in acute coronary syndromes.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To examine whether increasing cumulative deprivation has an incremental effect on total as well as cause specific mortality. DESIGN: Census data on housing conditions as indicators of deprivation from 1960, 1970, and 1980 were linked to 1990-98 death registrations. Relative indices of inequalities were computed for housing conditions to measure the cumulative impact of differences in social conditions. PARTICIPANTS: 97 381 (71.1%) 30-49 year old and 70701 (80.0%) 50-69 year old inhabitants of Oslo, Norway, in 1990 with census information on housing conditions and recorded length of education. MAIN RESULTS: Mortality risk was increased when all censuses' housing conditions were summed in both age groups and sex. The cause specific analysis indicated such an effect particularly for coronary heart disease, chronic obstructive lung disease, and smoking related cancers. Violent deaths were essentially associated with housing conditions closer to the time of death in men in both age groups and in young women. CONCLUSIONS: To fully account for socially mediated risk of death, a full life course approach should be adopted. The relative importance of each stage seems to vary by cause of death.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To examine the long-term incidence of diabetes in relation to coffee consumption in Swedish women. DESIGN: Prospective longitudinal cohort study. SETTING: City of Goteborg, Sweden. SUBJECTS: A random population sample of 1361 women, aged 39-65 years, without prior diabetes or cardiovascular disease took part in a screening study in 1979-1981 with questionnaires, physical examination and blood sampling. MAIN OUTCOME MEASURES: The development of diabetes until 1999 was identified by questionnaires in a second screening and the Swedish hospital discharge register. RESULTS: Altogether, there were 74 new cases of diabetes. The risk of developing diabetes was 475 per 100 000 person-years in women who consumed two cups of coffee or less per day, 271 in women who consumed three to four cups per day, 202 with a consumption of five to six cups per day, and 267 in drinkers of seven cups or more per day. Associated hazard ratios, after adjustment for age, smoking, low physical activity, education and body mass index were 0.55 (0.32-0.95), 0.39 (0.20-0.77) and 0.48 (0.22-1.06) for daily consumption of three to four, five to six and seven cups or more, respectively, with a consumption of less than two per day as reference. Additional adjustment for serum cholesterol and triglycerides attenuated the relation between coffee and diabetes slightly, indicating a possible mediating effect on the effect of coffee by serum lipids. CONCLUSIONS: The findings of the present study support the hypothesis that coffee consumption protects from the development of diabetes in women.

The Oslo Health Study: The impact of self-selection in a large, population-based survey
- 2004
-
Ingår i: Int J Equity Health. - 1475-9276. ; 3:1
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Research on health equity which mainly utilises population-based surveys, may be hampered by serious selection bias due to a considerable number of invitees declining to participate. Sufficient information from all the non-responders is rarely available to quantify this bias. Predictors of attendance, magnitude and direction of non-response bias in prevalence estimates and association measures, are investigated based on information from all 40 888 invitees to the Oslo Health Study. METHODS: The analyses were based on linkage between public registers in Statistics Norway and the Oslo Health Study, a population-based survey conducted in 2000/2001 inviting all citizens aged 30, 40, 45, 59-60 and 75-76 years. Attendance was 46%. Weighted analyses, logistic regression and sensitivity analyses are performed to evaluate possible selection bias. RESULTS: The response rate was positively associated with age, educational attendance, total income, female gender, married, born in a Western county, living in the outer city residential regions and not receiving disability benefit. However, self-rated health, smoking, BMI and mental health (HCSL) in the attendees differed only slightly from estimated prevalence values in the target population when weighted by the inverse of the probability of attendance.Observed values differed only moderately provided that the non-attending individuals differed from those attending by no more than 50%. Even though persons receiving disability benefit had lower attendance, the associations between disability and education, residential region and marital status were found to be unbiased. The association between country of birth and disability benefit was somewhat more evident among attendees. CONCLUSIONS: Self-selection according to sociodemographic variables had little impact on prevalence estimates. As indicated by disability benefit, unhealthy persons attended to a lesser degree than healthy individuals, but social inequality in health by different sociodemographic variables seemed unbiased. If anything we would expect an overestimation of the odds ratio of chronic disease among persons born in non-western countries.

- OBJECTIVE: Earlier studies and trials have shown a serum cholesterol raising effect of unfiltered coffee, which is reduced by about 80% in filtered coffee. Recent cross-sectional studies and trials, however, have indicated that filtered coffee may have a more pronounced serum cholesterol raising effect than previously anticipated. The objective of this controlled study was to assess the effects of the intake and abstention of filtered brewed coffee on blood lipids. DESIGN: A prospective, controlled study with four consecutive trial periods. The first and third periods were 3 weeks of total coffee abstention. The second and fourth periods consisted of 4 weeks with the subjects consuming 600 ml filter brewed coffee/day. SETTING: Free-living population. Volunteers. SUBJECTS: A total of 121 healthy, nonsmoking men and women aged 29-65 y. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Serum total cholesterol, serum HDL cholesterol, serum triglycerides, serum lipoprotein (a) (Lp(a)), blood pressure and heart rate. RESULTS: The two coffee abstention periods were associated with a decline in serum cholesterol of 0.22 mmol/l (95% CI -0.31, -0.13) and 0.36 mmol/l (95% CI -0.46, -0.26), respectively. Filtered coffee/day 600 ml increased serum cholesterol by 0.25 mmol/l (95% CI 0.15, 0.36) and 0.15 mmol/l (95% CI 0.04, 0.26) during the two coffee drinking periods. CONCLUSIONS: Coffee abstention for 3 weeks decreased total serum cholesterol by 0.22-0.36 mmol/l. A volume of 600 ml (about four cups) of filtered coffee/day during 4 weeks raised total serum cholesterol by 0.15-0.25 mmol/l.
