- Background - Despite a decline in mortality rates from cardiovascular disease (CVD) in the past few decades, the burden of CVD in a contemporary population remains inadequately addressed. Therefore, this study was aimed to investigate secular trends in mortality from coronary artery disease and all-cause mortality over 2 decades, by comparing 2 cohorts of men born 30 years apart and evaluate the prediction of the risk of CVD and all-cause death in a contemporary random sample of Swedish men.Methods and Results - Two cohorts of randomly selected men born in 1913 (855 men) and 1943 (798 men) were first examined at age 50 in 1963 and 1993, respectively, and followed longitudinally over 21 years. All-cause mortality and coronary artery disease death were lower in 50-to 71-year-old men born in 1943 compared with those born in 1913, with unadjusted hazard ratios of 0.57 (0.45-0.71) and 0.34 (0.22-0.53), respectively. After adjustment for risk factors (smoking, serum cholesterol, hypertension, systolic blood pressure, diabetes mellitus, body mass index, and physical activity), the differences between the cohorts remained significant for coronary artery disease, hazard ratios 0.57 (0.34-0.94), P=0.029, but not for all-cause mortality hazard ratios 0.82 (0.62-1.07), P=0.14. However, the rate of CVD events during follow-up was still high (30.7%) for the men born in 1943. No statistically significant interaction by birth cohort in contribution of risk factors to death was found between 2 cohorts except physical inactivity.Conclusions - Despite a marked reduction in the rate of coronary artery disease death over the past 30 years, the burden of CVD events and all-cause mortality remains high. Therefore, intensified efforts to modify contributing risk factors are still required.

Tidskriftsartikel (refereegranskat)abstract
- To investigate potential gender differences in the role of hypertension as a risk factor for metabolic syndrome (MetS) we used a random population sample of 50-year-old men (n=595) and women (n=667; all born in 1953) who were examined in 2003-2004. Systolic (SBP) and diastolic (DBP) blood pressure values were dichotomized at >/=140 mm Hg and >/=90 mm Hg, respectively. MetS was defined using NCEP (National Cholesterol Education Programme) and IDF (International Diabetes Federation) criteria. MetS was more prevalent in men than in women (NCEP 16% versus 10%, P=0.003; IDF 26% versus 16%, P=0.000) and systolic hypertension was more common in men than in women (high SBP 24% versus 18%, P=0.003; high DBP 29% versus 24%, P=0.074). Women with high SBP had about a seven-fold increased NCEP risk compared with normotensive women (odds ratio (OR) 6.91, confidence interval (CI) 2.90-16.42), whereas high SBP in men was associated with about a three-fold increased NCEP risk (OR 2.72, CI 1.69-4.38). A similar pattern was observed for the IDF criterion of MetS. All interaction terms (sex x hypertension) were significant at P<0.01. At middle age, despite that fewer women had hypertension or MetS than men, hypertension carries a relatively greater risk for MetS in women than in men.Journal of Human Hypertension advance online publication, 1 December 2011; doi:10.1038/jhh.2011.106.

- OBJECTIVE: To relate lipid levels in middle-aged men to that of their fathers at 50 years of age measured 30 years earlier. DESIGN AND SUBJECTS: In 1963, 855 men born in 1913 took part in a cardiovascular risk factor survey when they were at 50 years of age. In 1993, 475 sons to these men, aged 44-56, were invited to another examination; 263 of these men were examined (response rate: 56%) and compared with their 217 fathers when they were examined at 50 years of age in 1963. In the 1993 survey, 798 men aged 50, were also examined, from a general population sample of men born in 1943 (response rate: 55%). SETTING: City of Goteborg, Sweden. MAIN OUTCOME MEASURES: Serum lipids in sons as a function of lipids in their fathers. RESULTS: Compared with the men born in 1913, both sons and men born in 1943 had lower mean serum cholesterol, but higher body mass index (BMI) and serum triglycerides. There was a significant relation between serum cholesterol in sons and their fathers (r = 0.25; P < 0.0001). Amongst sons to fathers in the highest cholesterol quartile (>6.9 mmol x L(-1)), 37% had serum cholesterol above 6.5 mmol x L(-1), compared with 16% amongst sons to fathers in the lowest quartile (<5.7 mmol x L(-1)) [adjusted odds ratio 3.73 (1.52-9.12)]. Sons to fathers with the highest serum cholesterol levels had slightly lower BMI; otherwise there was no relation between serum cholesterol in the father and any other lifestyle or biological risk factor in the sons. Serum triglyceride concentration in the father was unrelated to any variable in the son. CONCLUSIONS: There was a moderately strong association between serum cholesterol concentration in fathers and sons at middle age. However, secular trends were also important in determining serum cholesterol concentrations in those born at a later period, indicating a major role of environmental factors.

- A random sample of men born in 1943 were asked about their views just before their 65th birthday (the common age of retirement in Sweden). 786 (64%) responded. They were divided into 4 groups: Group 1 (11%) retired before the age of 60, group 2 (25%) retired between the ages of 60 and 64, group 3 (22%) planned to retire around the age of 65, and group 4 (42%) planned to continue working after the age of 65. Men in group 1 reported more diseases and lower education than men in the other groups. Men in group 4 had higher education, more often office work, a partner who was still working and felt healthier than the other men. The men in group 4 were also happier with their work and had more influence on their working conditions than the other men, but they were worried about retiring too early.

- BACKGROUND: We have previously shown that insulin is not a major risk factor for CHD. Our data have been re-analysed with longer follow-up and the homeostasis model assessment (HOMA) method. DESIGN: Prospective cohort study of 57- and 67-year-old men. METHODS: Insulin resistance was estimated with the HOMA equation. Standard methods were used to measure risk factors. The endpoint (CHD) was the combination of non-fatal myocardial infarction and fatal CHD during 13 years of follow-up. RESULTS: The risk of CHD increased 2.5-fold in known diabetics compared with those with normal glucose tolerance, 2.2-fold among those in the highest compared with the lowest quintile of insulin resistance, and 2.4-fold among those in the highest compared with the lowest quintile of fasting insulin. Increased physical activity decreased the risk of CHD by 65%. Cholesterol was also a significant risk factor for CHD but blood pressure, obesity and smoking were not related to the incidence of CHD. CONCLUSION: Insulin resistance is a significant risk factor for CHD. Whether it is a causal risk factor remains to be proven. Regular physical activity protects against CHD.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND Random samples of 50-year-old men living in Gothenburg have been examined every 10th year since 1963 with a focus on cardiovascular risk factors. The aims of the study were to acquire up-to-date information about risk factors in the fifth cohort of 50-year-old men and women, to re-examine those who were 50 years of age in 1993, and to analyse the prevalence of the metabolic syndrome (MetSyn) using different definitions. METHODS A random sample of men and women born in 1953 were examined in 2003-2004 for cardiovascular risk factors. Men born in 1943 and that participated in the examination in 1993 were also invited. Descriptive statistics were calculated. RESULTS The participation rate among men and women born in 1953 was 60 and 67% respectively. Among men born in 1943, the participation rate was 87%. The prevalence of obesity was from 15 to 17% (body mass index, BMI >or= 30) in the three samples. The prevalence of known diabetes was 4% among the 50-year-old men and 6% among the 60-year-old men, and 2% among the women. Increased fasting plasma glucose varied substantially from 4 to 33% depending on cut-off level and gender. Mean cholesterol was 5.4 to 5.5 mmol/l. Smoking was more common among women aged 50 (26%) than among men aged 50 (22%) and 60 years (15%). The prevalence of the MetSyn varied with the definition used: from 10 to 15.8% among the women, from 16.1 to 26% among 50-year-old men, and from 19.9 to 35% among the 60-year-old men. Only 5% of the men and women had no risk factors. CONCLUSION This study provides up-to-date information about the prevalence of cardiovascular risk factors and the MetSyn in middle-aged Swedish men and women. Different definitions of the MetSyn create confusion regarding which definition to use.

- Background: During the past decades, declining trends in mean cholesterol levels and smoking have been observed in Western Europe, whereas obesity and a sedentary lifestyle have increased. Simultaneously, there has been a marked decrease in mortality from cardiovascular (CV) diseases. Methods: The aim of the study was to determine whether these trends in CV risk factors continued over a period of 50 years. Six systematic or random population samples of 50-year-old men (n = 3563) living in Gothenburg, Sweden, were investigated between 1963 and 2013. Results: During the 50 years, mean body mass index (BMI) at 50 years of age increased by 2 kg/m(2), from 24.8 kg/m(2) in 1963 to 26.8 kg/m(2) in 2013 (p< 0.001). A decrease in systolic blood pressure of nearly 10mmHg was observed from 1963 to 1993, but was not sustained through the past two decades. Mean serum cholesterol fell from 6.42 (SD 1.12) mmol/L to 5.34 (SD 0.97) mmol/L. The prevalence of smoking at 50 years of age decreased markedly from 56.1% in 1963 to 11.9% in 2013. The number of participants with a sedentary lifestyle during leisure time decreased until 1993, but has remained unchanged since. In 2013, 50-year-old men had a 6.9-times higher likelihood of lacking CV risk factors than 50-year-old men in 1963 (95% confidence interval (CI): 3.5-13.3, p< 0.001). The odds ratio for having four or more risk factors was only 0.13 (95% CI: 0.062-0.29, p< 0.001). Conclusion: Despite increasing body weight, the total CV risk factor burden has decreased in 50-year-old men over the past 50 years.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- The emergence of multidrug-resistant strains of Mycobacterium tuberculosis (MTB), the bacterium responsible for tuberculosis (TB), has rekindled the interest in the role of nutritional supplementation of micronutrients, such as vitamin D, as adjuvant treatment. Here, the growth of virulent MTB in macrophages obtained from the peripheral blood of patients with and without TB was studied. The H37Rv strain genetically modified to express Vibrio harveyi luciferase was used to determine the growth of MTB by luminometry in the human monocyte-derived macrophages (hMDMs) from study subjects. Determination of cytokine levels in culture supernatants was performed using a flow cytometry-based bead array technique. No differences in intracellular growth of MTB were observed between the different study groups. However, stimulation with 100nM 1,25-dihydroxyvitamin D significantly enhanced the capacity of hMDMs isolated from TB patients to control the infection. This effect was not observed in hMDMs from the other groups. The interleukin (IL)-1β and IL-10 release by hMDMs was clearly increased upon stimulation with 1,25-dihydroxyvitamin D. Furthermore, the 1,25-dihydroxyvitamin D stimulation also led to elevated levels of TNF-α (tumor necrosis factor-alpha) and IL-12p40. It was concluded that vitamin D triggers an inflammatory response in human macrophages with enhanced secretion of cytokines, as well as enhancing the capacity of hMDMs from patients with active TB to restrict mycobacterial growth.

Tidskriftsartikel (refereegranskat)abstract
- 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. 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. 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. 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 AND PURPOSE: The NeuroThera Effectiveness and Safety Trial-1 (NEST-1) study evaluated the safety and preliminary effectiveness of the NeuroThera Laser System in the ability to improve 90-day outcomes in ischemic stroke patients treated within 24 hours from stroke onset. The NeuroThera Laser System therapeutic approach involves use of infrared laser technology and has shown significant and sustained beneficial effects in animal models of ischemic stroke.METHODS: This was a prospective, intention-to-treat, multicenter, international, double-blind, trial involving 120 ischemic stroke patients treated, randomized 2:1 ratio, with 79 patients in the active treatment group and 41 in the sham (placebo) control group. Only patients with baseline stroke severity measured by National Institutes of Health Stroke Scale (NIHSS) scores of 7 to 22 were included. Patients who received tissue plasminogen activator were excluded. Outcome measures were the patients' scores on the NIHSS, modified Rankin Scale (mRS), Barthel Index, and Glasgow Outcome Scale at 90 days after treatment. The primary outcome measure, prospectively identified, was successful treatment, documented by NIHSS. This was defined as a complete recovery at day 90 (NIHSS 0 to 1), or a decrease in NIHSS score of at least 9 points (day 90 versus baseline), and was tested as a binary measure (bNIH). Secondary outcome measures included mRS, Barthel Index, and Glasgow Outcome Scale. Primary statistical analyses were performed with the Cochran-Mantel-Haenszel rank test, stratified by baseline NIHSS score or by time to treatment for the bNIH and mRS. Logistic regression analyses were conducted to confirm the results.RESULTS: Mean time to treatment was >16 hours (median time to treatment 18 hours for active and 17 hours for control). Time to treatment ranged from 2 to 24 hours. More patients (70%) in the active treatment group had successful outcomes than did controls (51%), as measured prospectively on the bNIH (P=0.035 stratified by severity and time to treatment; P=0.048 stratified only by severity). Similarly, more patients (59%) had successful outcomes than did controls (44%) as measured at 90 days as a binary mRS score of 0 to 2 (P=0.034 stratified by severity and time to treatment; P=0.043 stratified only by severity). Also, more patients in the active treatment group had successful outcomes than controls as measured by the change in mean NIHSS score from baseline to 90 days (P=0.021 stratified by time to treatment) and the full mRS ("shift in Rankin") score (P=0.020 stratified by severity and time to treatment; P=0.026 stratified only by severity). The prevalence odds ratio for bNIH was 1.40 (95% CI, 1.01 to 1.93) and for binary mRS was 1.38 (95% CI, 1.03 to 1.83), controlling for baseline severity. Similar results held for the Barthel Index and Glasgow Outcome Scale. Mortality rates and serious adverse events (SAEs) did not differ significantly (8.9% and 25.3% for active 9.8% and 36.6% for control, respectively, for mortality and SAEs).CONCLUSIONS: The NEST-1 study indicates that infrared laser therapy has shown initial safety and effectiveness for the treatment of ischemic stroke in humans when initiated within 24 hours of stroke onset. A larger confirmatory trial to demonstrate safety and effectiveness is warranted.

- BACKGROUND AND PURPOSE: The NeuroThera Effectiveness and Safety Trial-1 (NEST-1) study evaluated the safety and preliminary effectiveness of the NeuroThera Laser System in the ability to improve 90-day outcomes in ischemic stroke patients treated within 24 hours from stroke onset. The NeuroThera Laser System therapeutic approach involves use of infrared laser technology and has shown significant and sustained beneficial effects in animal models of ischemic stroke. METHODS: This was a prospective, intention-to-treat, multicenter, international, double-blind, trial involving 120 ischemic stroke patients treated, randomized 2:1 ratio, with 79 patients in the active treatment group and 41 in the sham (placebo) control group. Only patients with baseline stroke severity measured by National Institutes of Health Stroke Scale (NIHSS) scores of 7 to 22 were included. Patients who received tissue plasminogen activator were excluded. Outcome measures were the patients' scores on the NIHSS, modified Rankin Scale (mRS), Barthel Index, and Glasgow Outcome Scale at 90 days after treatment. The primary outcome measure, prospectively identified, was successful treatment, documented by NIHSS. This was defined as a complete recovery at day 90 (NIHSS 0 to 1), or a decrease in NIHSS score of at least 9 points (day 90 versus baseline), and was tested as a binary measure (bNIH). Secondary outcome measures included mRS, Barthel Index, and Glasgow Outcome Scale. Primary statistical analyses were performed with the Cochran-Mantel-Haenszel rank test, stratified by baseline NIHSS score or by time to treatment for the bNIH and mRS. Logistic regression analyses were conducted to confirm the results. RESULTS: Mean time to treatment was >16 hours (median time to treatment 18 hours for active and 17 hours for control). Time to treatment ranged from 2 to 24 hours. More patients (70%) in the active treatment group had successful outcomes than did controls (51%), as measured prospectively on the bNIH (P=0.035 stratified by severity and time to treatment; P=0.048 stratified only by severity). Similarly, more patients (59%) had successful outcomes than did controls (44%) as measured at 90 days as a binary mRS score of 0 to 2 (P=0.034 stratified by severity and time to treatment; P=0.043 stratified only by severity). Also, more patients in the active treatment group had successful outcomes than controls as measured by the change in mean NIHSS score from baseline to 90 days (P=0.021 stratified by time to treatment) and the full mRS ("shift in Rankin") score (P=0.020 stratified by severity and time to treatment; P=0.026 stratified only by severity). The prevalence odds ratio for bNIH was 1.40 (95% CI, 1.01 to 1.93) and for binary mRS was 1.38 (95% CI, 1.03 to 1.83), controlling for baseline severity. Similar results held for the Barthel Index and Glasgow Outcome Scale. Mortality rates and serious adverse events (SAEs) did not differ significantly (8.9% and 25.3% for active 9.8% and 36.6% for control, respectively, for mortality and SAEs). CONCLUSIONS: The NEST-1 study indicates that infrared laser therapy has shown initial safety and effectiveness for the treatment of ischemic stroke in humans when initiated within 24 hours of stroke onset. A larger confirmatory trial to demonstrate safety and effectiveness is warranted.

- Background: Atrial fibrillation is one of the most common arrhythmias in clinical practice and it is often diagnosed after a complication occurs. The study aimed to evaluate the predictive value of atrial natriuretic peptide (ANP) for atrial fibrillation in a male population-based study. Methods and results: This study is a part of the "Study of Men Born in 1913 and 1923", a longitudinal prospective cohort study of men, living in the city of Gothenburg in Sweden. A population-based sample of 528 men was investigated in 1988 when they were aged 65 years (n = 134) and 75 years (n = 394), and they were followed up for 16 years. Blood samples were collected from all 528 men at baseline and plasma ANP levels were analyzed by radioimmunoassay. Hazard ratios were estimated by competing-risk regression analysis. One hundred five participants were excluded because of a prior diagnosis of atrial fibrillation, congestive heart failure, severe hypertension, or severe chronic renal insufficiency. Of the remaining 423 participants, 90 men were diagnosed with atrial fibrillation over the 16-year follow-up. In multivariable analysis, men in the two highest quartiles of ANP levels had a significantly higher risk for atrial fibrillation compared with men in the lowest ANP quartile. The adjusted ratio was 3.14 (95% CI 1.59-6.20) for the third ANP quartile and 3.36 (95% CI 1.72-6.54) for the highest quartile of ANP level. Conclusions: In this population-based longitudinal study, we found that elevated ANP levels at baseline predicted atrial fibrillation during a follow-up time of 16 years.

- Aim This study aimed to estimate the prevalence, incidence rate, and lifetime risk of developing atrial fibrillation (AF) in a population-based study of Swedish men. Methods and results The study is a part of 'The Study of Men Born in 1913', which is a longitudinal prospective cohort study of 855 men born in 1913 and living in the city of Gothenburg in Sweden. They were followed from the age of 50 years until 98 years with repeated examinations and data from the Swedish National Hospital Discharge Register. A total of 185 (21.6%) men developed AF. The prevalence of AF increased from 0.4% at 50 years old, to 1.9% by 60 years old, to 4.6% by 70 years old, to 12.5% by 80 years old, and to 15.7% by 90 years old. The lifetime risk of developing AF was 22.5%. Conclusion Atrial fibrillation is rare at the age of 50 in Swedish men, but it increases exponentially with age, markedly accelerating after 70 years old. In nonagenarians, one of five men has or has had AF.

- 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.
