RESUMO
INTRODUCTION: Data on the prognostic value of hypertensive response to exercise in cardiovascular disease are limited. The aim was to determine whether SBP reactions during exercise have any prognostic value in relation to the long-term risk of stroke and myocardial infarction (MI). PATIENTS AND METHODS: A representative cohort of men from Gothenburg, Sweden, born in 1913, who performed a maximum exercise test at age 54 years, (nâ=â604), was followed-up for a maximum of 44 years with regard to stroke and MI. RESULTS: Among the 604 men, the mean resting and maximum SBP was 141.5 (SD 18.8) and 212.1 (SD 24.6)âmmHg, respectively. For maximum SBP, the risk of stroke increased by 34% (hazard ratio 1.34, 95% confidence interval 1.11-1.61) per 1-SD increase, while no risk increase was observed for MI. The highest risk of stroke among blood pressure groups was observed among men with a resting SBP of at least 140âmmHg and a maximum SBP of at least 210âmmHg with an hazard ratio of 2.09 (95% confidence interval 1.29-3.40), compared with men with a resting SBP of less than 140âmmHg and a maximum SBP of less than 210âmmHg, independent of smoking, blood glucose, cholesterol and BMI. CONCLUSION: Among middle-aged men with high resting and maximum blood pressure during maximum exercise workload, an increased risk of stroke was observed but not for MI. Further studies with larger sample sizes are needed to investigate the underlying mechanisms of the increased risk of stroke among individuals with hypertensive response to exercise.

Background and Purpose- To further improve preventive strategies against stroke, there is a need for epidemiological long-term studies. The study aimed at a prospective investigation of stroke determinants in the general male population. Methods- During a period of 48 years, from 50 to 98 years of age, a population-based sample of 854 men was followed using repeated medical examinations, lifestyle questionnaires, data from hospital records and the National Cause of Death Register. Results- Determinants of ischemic stroke were atrial fibrillation (hazard ratio [HR], 6.61; 95% CI, 4.47-9.77); mother dead from cardiovascular disease (HR, 1.53; 1.09-2.17); high education (HR, 0.81; 0.69-0.96); and high physical activity level during leisure time (HR, 0.68; 0.50-0.93). For hemorrhagic stroke heart rate (HR, 1.04; 1.01-1.06) and mother dead from stroke (HR, 3.56; 1.43-8.87) constituted an increased risk. Statistically significant determinants for all stroke were atrial fibrillation (HR, 5.34; 3.68-7.75); high diastolic blood pressure (HR, 1.02; 1.01-1.03); high body weight (HR, 0.96; 0.94-0.99); high educational level (HR, 0.79; 0.68-0.92); wide waist circumference (HR, 1.04; 1.01-1.07); smoking (HR, 1.25; 1.06-1.48); mother dead from cerebrovascular disease (HR, 1.43; 1.05-1.94); and diabetes mellitus (HR, 1.65; 1.02-2.68). Of all men diagnosed with atrial fibrillation, 88% had a stroke during follow-up. Conclusions- Atrial fibrillation was by far the strongest determinant of stroke during 48 years of follow-up in a male population sample followed until the age of 98 years. The results warrant improved prophylaxis through intense treatment of modifiable determinants.

INTRODUCTION: Hypothyroidism is a common disorder, appearing mainly in women although less frequently found in women with polycystic ovary syndrome (PCOS). The objective was to test the hypothesis that hyperandrogenism might protect against hypothyroidism. MATERIAL AND METHODS: The data from three prospective follow-up studies (up to 21 years) and one register study were compared: women with PCOS (Rotterdam criteria), n = 25, women with Turner syndrome, n = 217, a random population sample of women, n = 315, and men, n = 95 (the WHO MONICA study). Findings were to be verified or rejected in all females, n = 553 716, from the same region. The proportion of hypothyroidism was calculated and thyroid peroxidase antibodies (TPO) in serum were measured. RESULTS: Hypothyroidism at >50 years of age was found in 8% of women with PCOS, 4% in men (PCOS vs. men; ns), 43% of women with Turner syndrome, irrespective of karyotype (p < 0.001 vs. PCOS), and in 17% of postmenopausal women in the population (p < 0.01 vs. PCOS). Elevated TPO were similar in PCOS and women and men in the population but higher in Turner syndrome. Hypothyroidism increased with age in all groups except PCOS women and men. In the register study, hypothyroidism was less common in women with PCOS >25 years (5.5%) than in women without PCOS (6.8%) from the same region (p < 0.01). CONCLUSIONS: Hypothyroidism was less frequently seen in women with PCOS and in men compared with women in the general population and among women with Turner syndrome. This was not explained by altered autoimmunity or the Y-chromosome. Androgens seem to protect against hypothyroidism.

BACKGROUND: Low aerobic capacity has been associated with increased mortality in short-term studies. The aim of this study was to evaluate the predictive power of aerobic capacity for mortality in middle-aged men during 45-years of follow-up. DESIGN: The study design was a population-based prospective cohort study. METHODS: A representative sample from Gothenburg of men born in 1913 was followed from 50-99 years of age, with periodic medical examinations and data from the National Hospital Discharge and Cause of Death registers. At 54 years of age, 792 men performed an ergometer exercise test, with 656 (83%) performing the maximum exercise test. RESULTS: In Cox regression analysis, low predicted peak oxygen uptake ([Formula: see text]), smoking, high serum cholesterol and high mean arterial blood pressure at rest were significantly associated with mortality. In multivariable analysis, an association was found between predicted [Formula: see text] tertiles and mortality, independent of established risk factors. Hazard ratios were 0.79 (95% confidence interval (CI) 0.71-0.89; p < 0.0001) for predicted [Formula: see text], 1.01 (1.002-1.02; p < 0.01) for mean arterial blood pressure, 1.13 (1.04-1.22; p < 0.005) for cholesterol, and 1.58 (1.34-1.85; p < 0.0001) for smoking. The variable impact (Wald's χ(2)) of predicted [Formula: see text] tertiles (15.3) on mortality was secondary only to smoking (31.4). The risk associated with low predicted [Formula: see text] was evident throughout four decades of follow-up. CONCLUSION: In this representative population sample of middle-aged men, low aerobic capacity was associated with increased mortality rates, independent of traditional risk factors, including smoking, blood pressure and serum cholesterol, during more than 40 years of follow-up.

IMPORTANCE: The prevalence of cardiometabolic multimorbidity is increasing. OBJECTIVE: To estimate reductions in life expectancy associated with cardiometabolic multimorbidity. DESIGN, SETTING, AND PARTICIPANTS: Age- and sex-adjusted mortality rates and hazard ratios (HRs) were calculated using individual participant data from the Emerging Risk Factors Collaboration (689,300 participants; 91 cohorts; years of baseline surveys: 1960-2007; latest mortality follow-up: April 2013; 128,843 deaths). The HRs from the Emerging Risk Factors Collaboration were compared with those from the UK Biobank (499,808 participants; years of baseline surveys: 2006-2010; latest mortality follow-up: November 2013; 7995 deaths). Cumulative survival was estimated by applying calculated age-specific HRs for mortality to contemporary US age-specific death rates. EXPOSURES: A history of 2 or more of the following: diabetes mellitus, stroke, myocardial infarction (MI). MAIN OUTCOMES AND MEASURES: All-cause mortality and estimated reductions in life expectancy. RESULTS: In participants in the Emerging Risk Factors Collaboration without a history of diabetes, stroke, or MI at baseline (reference group), the all-cause mortality rate adjusted to the age of 60 years was 6.8 per 1000 person-years. Mortality rates per 1000 person-years were 15.6 in participants with a history of diabetes, 16.1 in those with stroke, 16.8 in those with MI, 32.0 in those with both diabetes and MI, 32.5 in those with both diabetes and stroke, 32.8 in those with both stroke and MI, and 59.5 in those with diabetes, stroke, and MI. Compared with the reference group, the HRs for all-cause mortality were 1.9 (95% CI, 1.8-2.0) in participants with a history of diabetes, 2.1 (95% CI, 2.0-2.2) in those with stroke, 2.0 (95% CI, 1.9-2.2) in those with MI, 3.7 (95% CI, 3.3-4.1) in those with both diabetes and MI, 3.8 (95% CI, 3.5-4.2) in those with both diabetes and stroke, 3.5 (95% CI, 3.1-4.0) in those with both stroke and MI, and 6.9 (95% CI, 5.7-8.3) in those with diabetes, stroke, and MI. The HRs from the Emerging Risk Factors Collaboration were similar to those from the more recently recruited UK Biobank. The HRs were little changed after further adjustment for markers of established intermediate pathways (eg, levels of lipids and blood pressure) and lifestyle factors (eg, smoking, diet). At the age of 60 years, a history of any 2 of these conditions was associated with 12 years of reduced life expectancy and a history of all 3 of these conditions was associated with 15 years of reduced life expectancy. CONCLUSIONS AND RELEVANCE: Mortality associated with a history of diabetes, stroke, or MI was similar for each condition. Because any combination of these conditions was associated with multiplicative mortality risk, life expectancy was substantially lower in people with multimorbidity.

BACKGROUND AND AIMS: Exposure to air pollution has been linked to total and cardiopulmonary mortality. However, few studies have examined the effects of exposure over decades, or which time windows of long term exposure are most relevant. We investigated the long term effects of residential air pollution on total and cause-specific mortality and incidence of myocardial infarction in a well-characterized cohort of men in Sweden. METHODS: A cohort of 7494 men in Gothenburg was examined in 1970-1973 and followed subsequently to determine predictors of cardiovascular disease. We collected data on residential address and cause-specific mortality for the years 1973-2007. Each individual was assigned yearly nitrogen oxides (NOx) exposure based on dispersion models. Using multivariable Cox regression and generalized additive models with time-dependent exposure, we studied the association between three different time windows of residential NOx exposure, and selected outcomes. RESULTS: In the years 1973-2007, a total of 5669 deaths, almost half of which were due to cardiovascular diseases, occurred in the cohort. Levels of NOx exposure decreased during the study period, from a median of 38 µg/m(3) in 1973 to 17 µg/m(3) in 2007. Total non-accidental mortality was associated with participants' NOx exposure in the last year (the year of outcome) (HR 1.03, 95% CI 1.01-1.05, per 10 µg/m(3)), with the mean NOx exposure during the last 5 years, and with the mean NOx exposure since enrolment (HR 1.02, 95% CI 1.01-1.04 for both). The associations were similar (HR 1.01-1.03), but generally not statistically significant, for cardiovascular, ischemic heart disease, and acute myocardial infarction mortality, and weaker for cerebrovascular and respiratory mortality. There was no association between NOx exposure and incident myocardial infarction. DISCUSSION AND CONCLUSIONS: Long term residential exposure to NOx at these relatively low exposure levels in Gothenburg was associated with total non-accidental mortality. The association was as strong for NOx exposure in the last year as for longer exposure windows. The effect was near linear, and only marginally affected by confounders and effect modifiers. The improved air quality in Gothenburg has by these estimates led to a 6% decrease in excess non-accidental mortality during the study period.

OBJECTIVES: To examine causes of death for men above 80 years of age, and health status in centenarians in a cohort of men followed from age 50 years. Factors of importance for survival were studied. DESIGN: A representative sample of men born in 1913 was first examined in 1963 and re-examined at ages 54, 60, 67, 75, 80 and 100 years. RESULTS: Of 973 selected men, 855 (88%) were examined at age 50, and 10 were alive at age 100.Twenty-seven percent lived until 80 years. Cardiovascular disease was the most common cause of death after this age. Dementia was recorded in two of ten men at age 100. Long survival was related to the mothers' high age at death, to non-smoking, high social class at age 50 and high maximum working capacity at age 54 years. At age 100, the seven examined men had low/normal blood pressure. Serum values of troponin T, N-terminal pro-brain natriuretic peptides and C-reactive protein were elevated, but echocardiographic findings were normal. CONCLUSIONS: Ten men experienced their 100th birthday. Survival was related to non-smoking, mothers' high age at death, high social class and previous high physical working capacity. Age-adjusted reference levels for laboratory tests are needed for centenarians.

This study examined variations in stroke incidence across occupational classes over a 35-year follow-up period. We analyzed a random population-based sample of 6,994 men aged 47-56 years at baseline without prior history of stroke. Standardized incidence rates, subdistribution hazard ratios (SHRs) from competing risk regressions and cumulative incidence were calculated, after accounting for risk of death attributed to causes other than stroke. A total of 1,442 strokes were identified over the 35-year period with crude incidences of 5.50 (ischemic) and 1.16 (hemorrhagic) per 1,000 person-years. In the whole group, occupational class was not associated with either ischemic or hemorrhagic stroke. However, older men (≥51 years at baseline) with unskilled manual occupations had a significantly lower risk of ischemic stroke than those with high officials (referent). No association between occupation and stroke of either type was detected for men younger than 51 years. There was an inverse and graded risk of death from causes other than stroke; men in high official positions had the lowest cumulative risk and unskilled manual workers had the highest risk (P < 0.0001). The association between occupation and ischemic stroke in older men persisted after accounting for competing risks of death (SHR 0.62; 95 % CI 0.46-0.84). In conclusion, low socioeconomic status was not associated with an increased risk of incident hemorrhagic or ischemic stroke. Older men with the lowest occupational status i.e. unskilled manual had a significantly lower risk of ischemic stroke, even after controlling for other risk factors and competing risks of death.

AIMS: The aim of this study was to examine the short-term and long-term cumulative risk of coronary heart disease (CHD) and stroke separately based on age, sex, smoking status, systolic blood pressure, and total serum cholesterol. METHODS AND RESULTS: The Primary Prevention Study comprising 7174 men aged between 47 and 55 free from a previous history of CHD, stroke, and diabetes at baseline examination (1970-73) was followed up for 35 years. To estimate the cumulative effect of CHD and stroke, all participants were stratified into one of five risk groups, defined by their number of risk factors. The estimated 10-year risk for high-risk individuals when adjusted for age and competing risk was 18.1% for CHD and 3.2% for stroke which increased to 47.8 and 19.6%, respectively, after 35 years. The estimates based on risk factors performed well throughout the period for CHD but less well for stroke. CONCLUSION: The prediction of traditional risk factors (systolic blood pressure, total serum cholesterol, and smoking status) on short-term risk (0-10 years) and long-term risk (0-35 years) of CHD of stroke differs substantially. This indicates that the cumulative risk in middle-aged men based on these traditional risk factors can effectively be used to predict CHD but not stroke to the same extent.

BACKGROUND: Simple global self-ratings of health (SRH) have become increasingly used in national and international public health monitoring, and in recent decades recommended as a standard part of health surveys. Monitoring developments in population health requires identification and use of health measures, valid in relation to targets for population health. The aim of the present study was to investigate associations between SRH and sick leave, disability pension, hospital admissions, and mortality, adjusted for effects of significant covariates, in a large population-based cohort. METHODS: The analyses were based on screening data from eight population-based cohorts in southern and central Sweden, and on official register data regarding sick-leave, disability pension, hospital admissions, and death, with little or no data loss. Sampling was performed 1973-2003. The study population consisted of 11,880 women and men, age 25-99 years, providing 14,470 observations. Information on SRH, socio-demographic data, lifestyle variables and somatic and psychological symptoms were obtained from questionnaires. RESULTS: There was a significant negative association between SRH and sick leave (Beta -13.2, p<0.0001, and -9.5, p<0.01, in women and men, respectively), disability pension (Hazard ratio 0.77, p<0.0001 and 0.76, p<0.0001, in women and men, respectively), and mortality, adjusted for covariates. SRH was also significantly associated with hospital admissions in men (Hazard ratio 0.87, p<0.0001), but not in women (Hazard ratio 0.96, p0.20). Associations between SRH on the one hand, and sick leave, disability pension, hospital admission, and mortality, on the other, were robust during the follow-up period. CONCLUSIONS: SRH had strong predictive validity in relation to use of social insurance facilities and health care services, and to mortality. Associations were strong and robust during follow-up.

BACKGROUND: The link between type 2 diabetes and hypertension is well established and the conditions often coexist. High normal blood pressure, defined by WHO-ISH as systolic blood pressure (SBP) 130-139 mm Hg or diastolic blood pressure (DBP) 85-89 mm Hg, has been found to be an independent predictor for type 2 diabetes in studies, although with relatively limited follow-up periods of approximately 10 years. The aim of this study was to investigate whether hypertension, including mildly elevated blood pressure within the normal range, predicted subsequent development of type 2 diabetes in men over an extended follow-up of 35 years. METHODS: Data were derived from the Gothenburg Primary Prevention Study where a random sample of 7 494 men aged 47-55 years underwent a baseline screening investigation in the period 1970-1973. A total of 7 333 men were free from previous history of diabetes at baseline. During a 35-year follow-up diabetes was identified through the Swedish hospital discharge and death registries. The cumulative risk of diabetes adjusted for age and competing risk of death was calculated. Using Cox proportional hazard models we calculated the multiple adjusted hazard ratios (HR) (95% confidence interval (CI)) for diabetes at different blood pressure levels. RESULTS: During a 35-year follow-up, 956 men (13%) were identified with diabetes. The 35-year cumulative risk of diabetes after adjusting for age and competing risk of death in men with SBP levels <130 mm Hg, 130-139 mm Hg, 140-159 mm Hg and ≥160 mm Hg were 19%, 30%, 31% and 49%, respectively. The HR for diabetes adjusted for age, body mass index (BMI), cholesterol, antihypertensive treatment, smoking, physical activity and occupation were 1.43 (95% CI 1.12-1.84), 1.43 (95% CI 1.14-1.79) and 1.95 (95% CI 1.55-2.46) for men with SBP 130-139 mm Hg, 140-159 mm Hg, and ≥ 160 mm Hg, respectively (reference; SBP<130 mm Hg). CONCLUSION: In this population, at mid-life, even high-normal SBP levels were shown to be a significant predictor of type 2 diabetes, independently of BMI and other conventional type 2 diabetes risk factors over an extended follow-up.

OBJECTIVE: To study secular trends in sex hormones, anthropometry, bone measures and fractures. DESIGN: A random population sample was studied twice and subjects of similar age group were compared 13 years apart. METHODS: X-ray-verified fractures were retrieved from a random population sample of 2400 men and women (participants 1616=67%) aged 25-64 years from the WHO, MONICA Project in Gothenburg, Sweden, in 1995 and 2008. Fasting serum hormones and calcaneal ultrasound were measured in every fourth subject. In fertile women, measurements were performed on cycle day interval 7-9. RESULTS: In 2008, men had lower serum free testosterone than men of similar age in 1995 (P<0.001). Body composition, physical activity and fracture incidence were similar. In women, hormone replacement therapy (HRT) was lower in 2008, 7 vs 28% (P<0.0001), as was serum oestradiol, although use of tranquilisers and leisure time physical activity were higher. In 2008, the fracture incidence was higher in postmenopausal women, 29 vs 17% (P<0.001), and vertebral crush had increased from 8 to 19% of all fractures (P=0.031). Serum cholesterol and triglycerides were lower in all subjects in 2008 compared with that in 1995. CONCLUSIONS: Secular trends were observed with lower serum testosterone in men in 2008, but no effect was seen on the fracture incidence of these fairly young men. In postmenopausal women in 2008, there was a higher fracture incidence along with more vertebral compressions. Lower HRT use, lower serum oestradiol and higher fall risk exposure due with more tranquilisers and leisure time physical activity in 2008 may explain the results.

The aim of this paper is to review and discuss current methods of risk stratification for cardiovascular disease (CVD) prevention, emerging biomarkers, and imaging techniques, and their relative merits and limitations. This report is based on discussions that took place among experts in the area during a special CardioVascular Clinical Trialists workshop organized by the European Society of Cardiology Working Group on Cardiovascular Pharmacology and Drug Therapy in September 2009. Classical risk factors such as blood pressure and low-density lipoprotein cholesterol levels remain the cornerstone of risk estimation in primary prevention but their use as a guide to management is limited by several factors: (i) thresholds for drug treatment vary with the available evidence for cost-effectiveness and benefit-to-risk ratios; (ii) assessment may be imprecise; (iii) residual risk may remain, even with effective control of dyslipidemia and hypertension. Novel measures include C-reactive protein, lipoprotein-associated phospholipase A(2) , genetic markers, and markers of subclinical organ damage, for which there are varying levels of evidence. High-resolution ultrasound and magnetic resonance imaging to assess carotid atherosclerotic lesions have potential but require further validation, standardization, and proof of clinical usefulness in the general population. In conclusion, classical risk scoring systems are available and inexpensive but have a number of limitations. Novel risk markers and imaging techniques may have a place in drug development and clinical trial design. However, their additional value above and beyond classical risk factors has yet to be determined for risk-guided therapy in CVD prevention.

This paper presents a summary of the potential practical and economic barriers to implementation of primary prevention of cardiovascular disease guided by total cardiovascular risk estimations in the general population. It also reviews various possible solutions to overcome these barriers. The report is based on discussion among experts in the area at a special CardioVascular Clinical Trialists workshop organized by the European Society of Cardiology Working Group on Cardiovascular Pharmacology and Drug Therapy that took place in September 2009. It includes a review of the evidence in favour of the "treat-to-target" paradigm, as well as potential difficulties with this approach, including the multiple pathological processes present in high-risk patients that may not be adequately addressed by this strategy. The risk-guided therapy approach requires careful definitions of cardiovascular risk and consideration of clinical endpoints as well as the differences between trial and "real-world" populations. Cost-effectiveness presents another issue in scenarios of finite healthcare resources, as does the difficulty of documenting guideline uptake and effectiveness in the primary care setting, where early modification of risk factors may be more beneficial than later attempts to manage established disease. The key to guideline implementation is to improve the quality of risk assessment and demonstrate the association between risk factors, intervention, and reduced event rates. In the future, this may be made possible by means of automated data entry and various other measures. In conclusion, opportunities exist to increase guideline implementation in the primary care setting, with potential benefits for both the general population and healthcare resources.

BACKGROUND: Although cardiovascular disease (CVD) is the biggest global cause of death, CVD mortality is falling in developed countries. There is concern that this trend may be offset by increasing levels of obesity. DESIGN: We used the Systematic Coronary Risk Evaluation (SCORE) data set to examine relationships between body mass index (BMI), conventional risk factors and CVD mortality. METHODS: The SCORE data set comprises data from 12 European cohort studies. The relationship between BMI and CVD mortality was examined in each BMI category using univariable and multivariable (Cox) analyses. The SCORE population was also divided into gender and age strata: under 40, 40-49, 50-59, and over 60. The rate of CVD mortality in each BMI category was calculated within each gender and age stratum. Relationships between BMI and other CVD risk factors were also examined. RESULTS: There was a strong, graded but J-shaped univariable relationship between BMI and CVD mortality in both genders. Each 5-unit increase in BMI was associated with an increase in CVD mortality of 34% in men and 29% in women. The hazard ratios remained significant when adjusted for age, self-reported smoking status, total cholesterol, and systolic blood pressure (SBP). On additional adjustment for diabetes and high-density lipoprotein cholesterol (HDL), the association between BMI and CVD mortality did not persist. In all age groups except those over 60 there were significant relationships between increased BMI and CVD mortality. In the over-60 age group the only significant relationships with mortality were in underweight and severely overweight women and mildly obese men. After adjustment for age, each 1-unit increase in BMI was associated with a 1.14 mmHg increase in SBP, 0.055 mmol/l increase in total cholesterol, and a 0.024 mmol/l decrease in HDL in men. Figures were slightly lower in women. CONCLUSIONS: Overall, overweight and obesity relate to CVD mortality in a strong and graded manner. The effects are greater in women and markedly so in younger persons. It is likely that a substantial part of the BMI-associated risk of CVD mortality is mediated through other known CVD risk factors. This increases the public health importance of BMI as both a simple indicator and mediator of CVD risk.

BACKGROUND: Population-based study of a random sample of 50-year-old men and women in Gothenburg, Sweden. OBJECTIVE: To examine the determinants of perceived health and the differences between 50-year-old men and women. METHODS: Men and women born in 1953 were examined between 2003 and 2004. Participation rate was 60% among the men and 67% among the women. Questionnaires were used, including one on perceived health that was ranked on a 7-point scale from 1 (excellent) to 7 (very poor). The participants' medical histories were obtained through a questionnaire, and risk factors were measured. RESULTS: Women generally perceived their health as poorer than men. Women experienced more symptoms than men, and most symptoms were more prevalent among women than men. Poor perceived health was strongly related to number of symptoms. In multivariable analyses 5 factors were related to perceived health in both men and women: working full or part time (women OR [odds ratio] = 0.3, men OR = 0.3) and physical activity (women OR = 0.6, men OR = 0.6) had a positive effect, whereas a low level of social activities (women OR = 1.9, men OR = 1.7), still feeling tired after normal hours of sleep (women OR = 4.5, men OR = 4.0), and feeling burned out during the past 12 months (women OR = 2.3, men OR = 3.0) had a negative effect on perceived health. CONCLUSIONS: Women perceive their health as "worse" in comparison with men. Perceived health is a multifaceted condition related to social circumstances, physical activity, various symptoms, and tiredness after normal hours of sleep both in women and men.

BACKGROUND: Drug costs are increasing despite the introduction of cheaper generic drugs. The aim of the present study was to analyse the entire costs of hospital care, out-patient care, and the cost of drugs for 16 months following a myocardial infarction (MI) to see to what extent drug costs contribute to the overall costs of care. METHODS: Diagnoses and costs for care as well as mortality data obtained from the Västra Götaland Region, Sweden, and drug costs from the Swedish Board of Health and Welfare, were merged in a computer file. Patients registered from 1 July 2005 to 30 June 2006 were followed from 28 days after an MI, with follow-up until 31 October 2006. RESULTS: Of 4,725 patients, 711 died before the start of the study and 721 during follow-up. Higher age [hazard ratio (HR, 95%CI) = 1.06 (1.05-1.07)], previous MI [HR = 1.31 (1.13-1.53)] and diabetes mellitus [HR = 1.34 (1.13-1.58)] were associated with increased mortality, which decreased with coronary interventions: CABG/PCI [HR = 0.19 (0.14-0.27)]. In a multivariable analysis, mortality was lower for patients taking simvastatin [HR = 0.62 (0.50-0.76)] and clopidogrel [HR = 0.58 (0.46-0.74)]. CONCLUSION: Costs for out-patient care accounted for 25% and drugs for 5% of total costs. If patients not treated with simvastatin or clopidogrel had received these drugs, an additional 154-306 lives might have been saved. Drug costs would be higher, but total costs lower. Thus, even expensive drugs may reduce overall costs.
