OBJECTIVES: Previous studies have suggested that abnormal levels of cortisol and testosterone might increase the risk of serious somatic diseases. To test this hypothesis, we conducted a 5-year follow-up study in middle-aged men. METHODS: A population-based cohort study conducted in 1995 amongst 141 Swedish men born in 1944, in whom a clinical examination supplemented by medical history aimed to disclose the presence of cardiovascular disease (CVD) (myocardial infarction, angina pectoris, stroke), type 2 diabetes and hypertension were performed at baseline and at follow-up in the year 2000. In addition, salivary cortisol levels were measured repeatedly over the day. Serum testosterone concentrations were also determined. Using the baseline data, an algorithm was constructed, which classified the secretion pattern of cortisol and testosterone from each individual as being normal or abnormal. RESULTS: By the end of follow-up, men with an abnormal hormone secretion pattern (n = 73) had elevated mean arterial pressure (P = 0.003), fasting insulin (P = 0.009) and insulin : glucose ratio (P = 0.005) compared with men with a normal secretion pattern (n = 68). Body mass index, waist circumference, and waist : hip ratio were significantly elevated in both groups. However, the 5-year incidence of CVD, type 2 diabetes, and hypertension were significantly higher (P
Changes in the incidence of myocardial infarction, and associated mortality and lethality rates are reviewed over a 8-year period in an Novosibirsk district. Data on late postinfarction outcomes, obtained in a WHO-sponsored study, "Acute myocardial infarction register", are also presented. The incidence, mortality and lethality rates are showing a stabilization trend at present; in late outcomes, the greatest mortality and lethality rates fall to the first postinfarction year.
BACKGROUND: Previous studies of the risk of heart disease after shift work reached different estimates and review authors disagree about the validity of some of the studies. A cross sectional study showed that shift workers had a higher prevalence of nearly every unfavourable work environment factor investigated. Conflicts at work and low decision latitude were more frequent among shift workers, and all-day walking or standing work and part-time jobs were more often found among female shift workers. OBJECTIVES: To estimate the risk of circulatory disease in a prospective follow up of a representative sample of gainfully employed Danes, considering known or suspected confounding factors. METHODS: A cohort of 5517 people who were gainfully employed in 1990 were followed up for all hospital treatments due to circulatory diseases (390-458, ICD-8; I00-I99, ICD-10) from 1991 to 2002 inclusive. A log linear Poisson regression model was applied to control confounding factors and calculate the relative risk for 927 men and women working nights, evenings, or other non-day shifts compared to 4579 day workers. RESULTS: Non-day workers compared to day workers had a relative risk (RR) for all circulatory diseases of 1.31 (95% CI 1.06-1.63). Without control for BMI and smoking, the RR estimate was 1.33 (95% CI 1.07-1.65). For a subgroup of workers with at least three years' seniority, the RR was 1.40 (95% CI 1.09-1.81). The population based aetiological fraction of shift work was estimated to 5%. CONCLUSION: This study adds to a growing body of evidence suggesting that shift work carries an excess risk of circulatory diseases.
AIM: To reveal trends in incidence rates of acute cardiovascular diseases (ACD) in a large industrial city of the West Siberia. MATERIALS AND METHODS: Studies on WHO programs "Acute Myocardial Infarction Register" and "MONICA" have been performed in three districts of Novosibirsk. The diagnostic categories were detected without difference. The observation covered stable population of 500,000 residents aged 25-64 years. Trends in the myocardial infarction (MI) mortality, morbidity and lethality were analysed for 1977-1996. RESULTS: The above trends were stable except for 1986 when MI mortality, morbidity and lethality decreased and 1988 and 1994 when they went up. The reduction was due to 7-year prevention program while the rise was consequent to discontinuation of the preventive measures. Major risk factors of ischemic heart disease, according to screenings conducted in 1984, 1988 and 1994 remained at about the same level. Social stress closely correlates with a rise in MI morbidity and mortality. The latter in 1994 grew owing to higher rates of MI mortality and morbidity among the oldest men and females of different age groups. CONCLUSION: Urgent intensification of prophylactic measures is needed both at the populational level and the level of high risk strategy.
To study peculiar features of daily AP rhythm and profile in men with cardiovascular risk factors residing in the Far North.
The study included 115 servicemen divided into 3 groups (hypertensive disease (HD), hypertonic type neurocirculatory asthenia (NCA) and risk factor of cardiovascular diseases other than AH). HD was diagnosed based on multiple AP measurements and 24-hr monitoring.
HD was associated with elevated mean AP, load indices and AP variability All patients had pathological type of morning dynamics. Normal daily rhythm of systolic AP (SAP) was documented in 66.1% of the patients with HD and in 68% with cardiovascular risk factors without AH. Normal daily rhythm ofdiastolic AP (DAP) was recorded in 63.5% of the patients with HD and in 72% with cardiovascular risk factors without AH. In group 2, normal daily rhythms of SAP and DAP were found in 44 and 56% of the cases respectively.
Men residing in the Far North under conditions of anomalous photoperiod need medicamentous correction of AP regardless of AH type. Ambulatory BP monitoring should be preferred for the assessment of the efficacy of antihypertensive therapy.
OBJECTIVE: To investigate the longitudinal relationship between body mass index (BMI), a major vascular risk factor, and cerebral atrophy, a marker of neurodegeneration, in a population-based sample of middle-aged women. METHODS: A representative sample of 290 women born in 1908, 1914, 1918, and 1922 was examined in 1968 to 1969, 1974 to 1975, 1980 to 1981, and 1992 to 1993 as part of the Population Study of Women in Göteborg, Sweden. At each examination, women completed a survey on a variety of health and lifestyle factors and underwent anthropometric, clinical, and neuropsychiatric assessments and blood collection. Atrophy of the temporal, frontal, occipital, and parietal lobes was measured on CT in 1992 when participants were age 70 to 84. Univariate and multivariate regression analyses were used to assess the relationship between BMI and brain measures. RESULTS: Women with atrophy of the temporal lobe were, on average, 1.1 to 1.5 kg/m2 higher in BMI at all examinations than women without temporal atrophy (p

Persons with Alzheimer's disease (AD) have been suggested to receive suboptimal treatment. We studied the 30-day mortality after ischemic stroke, hemorrhagic stroke, or myocardial infarction in individuals with or without AD.
An exposure matched cohort of all Finnish community-dwellers diagnosed with clinically verified AD in 2005-2012 (n?=?73,005) and 1-4 matched comparison persons/AD-affected person (n?=?215,449). Data on 30-day mortality after ischemic stroke (n?=?16,419; deaths: n?=?2,748), hemorrhagic stroke (n?=?3,570; deaths: n?=?1,224), and myocardial infarction (n?=?15,304; deaths: n?=?3,804) were obtained from the National Hospital Discharge register. The main analyses were restricted to first-ever events.
Persons with AD had slightly higher 30-day mortality after ischemic stroke (adjusted HR 1.36, 95% Confidence interval (CI) 1.24,1.49), hemorrhagic stroke (adjusted HR 1.11, 95% CI 0.98,1.25), or myocardial infarction (adjusted HR, 1.40, 9% CI 1.30,1.51). The associations were not affected by age, gender, or co-morbidities and remained similar when patients with previous ischemic strokes or infarctions were included. The absolute risk increase in 30-day mortality after ischemic or hemorrhagic stroke and myocardial infarction were 4.9% (95% CI 3.3,6.5), 3.3% (95% CI - 1.6,8.2), and 7.5% (95% CI 5.0,10.0), respectively.
Although the 30-day mortality was somewhat higher in the AD cohort, the absolute differences were small indicating that acute treatment was not notably inferior in AD patients. The slightly higher mortality was not explained by co-morbidities but may reflect the higher mortality of AD persons in general, or treatment practice of patients with severe cognitive impairment.
We describe the 40-year weight history and adult morbidity and mortality in a cohort of 504 overweight children, aged 2 months to 16 years, who were admitted for investigation of their overweight to four children's hospitals in Stockholm between 1921 and 1947. Follow-up information was gathered by questionnaire at 10-year intervals, most recently in 1980-1983 (n = 458), on weight history (based on the body mass index (BMI = kg/m2)), as well as prevalence of cardiovascular disease (n = 143), diabetes (n = 39), and cancer (all types (n = 20)), reported during the 40 years of follow-up, and mortality from all causes (n = 55), determined from death certificate. The sample of overweight children remained overweight as adults; after age 55 years, the BMI began to decline for both genders. Female subjects were heavier than their male counterparts from postpuberty onward. Subjects who died by the 40-year follow-up and those reporting cardiovascular disease were significantly (P
To provide updated, evidence-based recommendations for the diagnosis and assessment of adults with hypertension.
MEDLINE searches were conducted from November 2008 to October 2009 with the aid of a medical librarian. Reference lists were scanned, experts were contacted, and the personal files of authors and subgroup members were used to identify additional studies. Content and methodological experts assessed studies using prespecified, standardized evidence-based algorithms. Recommendations were based on evidence from peer-reviewed full-text articles only.
Recommendations for blood pressure measurement, criteria for hypertension diagnosis and follow-up, assessment of global cardiovascular risk, diagnostic testing, diagnosis of renovascular and endocrine causes of hypertension, home and ambulatory monitoring, and the use of echocardiography in hypertensive individuals are outlined. Changes to the recommendations for 2010 relate to automated office blood pressure measurements. Automated office blood pressure measurements can be used in the assessment of office blood pressure. When used under proper conditions, an automated office systolic blood pressure of 135 mmHg or higher or diastolic blood pressure of 85 mmHg or higher should be considered analogous to a mean awake ambulatory systolic blood pressure of 135 mmHg or higher and diastolic blood pressure of 85 mmHg or higher, respectively.
All recommendations were graded according to strength of the evidence and voted on by the 63 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. To be approved, all recommendations were required to be supported by at least 70% of task force members. These guidelines will continue to be updated annually.
