Forskningsöversikt (refereegranskat)abstract
- BACKGROUND: A large number of observational epidemiological studies have reported generally positive associations between circulating mass and activity levels of lipoprotein-associated phospholipase A2 (Lp-PLA2) and the risk of cardiovascular diseases. Few studies have been large enough to provide reliable estimates in different circumstances, such as in different subgroups (e.g., by age group, sex, or smoking status) or at different Lp-PLA2 levels. Moreover, most published studies have related disease risk only to baseline values of Lp-PLA2 markers (which can lead to substantial underestimation of any risk relationships because of within-person variability over time) and have used different approaches to adjustment for possible confounding factors. OBJECTIVES: By combination of data from individual participants from all relevant observational studies in a systematic 'meta-analysis', with correction for regression dilution (using available data on serial measurements of Lp-PLA2), the Lp-PLA2 Studies Collaboration will aim to characterize more precisely than has previously been possible the strength and shape of the age and sex-specific associations of plasma Lp-PLA2 with coronary heart disease (and, where data are sufficient, with other vascular diseases, such as ischaemic stroke). It will also help to determine to what extent such associations are independent of possible confounding factors and to explore potential sources of heterogeneity among studies, such as those related to assay methods and study design. It is anticipated that the present collaboration will serve as a framework to investigate related questions on Lp-PLA2 and cardiovascular outcomes. METHODS: A central database is being established containing data on circulating Lp-PLA2 values, sex and other potential confounding factors, age at baseline Lp-PLA2 measurement, age at event or at last follow-up, major vascular morbidity and cause-specific mortality. Information about any repeat measurements of Lp-PLA2 and potential confounding factors has been sought to allow adjustment for possible confounding and correction for regression dilution. The analyses will involve age-specific regression models. Synthesis of the available observational studies of Lp-PLA2 will yield information on a total of about 15 000 cardiovascular disease endpoints.

- Background There is growing evidence that erectile dysfunction is a sentinel for future coronary artery disease. Recently published studies have shown signs of impaired coronary endothelial function in patients with erectile dysfunction, without clinical cardiovascular disease and diabetes. We evaluated the magnitude of coronary vasodilatory dysfunction in men with erectile dysfunction, as compared with men with impaired glucose metabolism (impaired fasting glucose or diabetes) and healthy controls. Methods We investigated men aged 68-73 years with erectile dysfunction (n=12), age-matched men with impaired glucose metabolism, who all proved to have erectile dysfunction (n=15), and age-matched male controls (n=12). Erectile dysfunction was evaluated using the International Index of Erectile Function (IIEF)-5 questionnaire. Coronary flow velocity reserve in the left anterior descending artery was examined using Doppler ultrasound and intravenous adenosine provocation. Results Coronary flow velocities at rest did not differ between the three groups, but maximum coronary flow velocity was significantly lower in the erectile dysfunction group (P= 0.004) and in the impaired glucose metabolism group (P= 0.019), as compared with controls. There was no difference between the erectile dysfunction and impaired glucose metabolism groups. Coronary flow velocity reserve was reduced in the erectile dysfunction group (P=0.026) compared to controls, but was similar compared to the impaired glucose metabolism group. In multivariate analysis including all groups, erectile dysfunction score was the only independent predictor of reduced coronary flow velocity reserve (P=0.020). Conclusions The magnitude of early coronary endothelial and smooth muscle cell dysfunction in otherwise healthy men with erectile dysfunction was comparable to that of patients with impaired glucose metabolism: a well known risk factor for coronary artery disease.

- Background Complement factor C3 and C4 have been associated with atherosclerosis and cardiovascular risk factors. This study explored whether plasma levels of C3 and C4 are risk factors for the incidence of cardiovascular disease (CVD). Design A population-based prospective study of 5850 initially healthy men, 28-61 years old at baseline. Methods Plasma levels of C3 and C4 were analysed at the baseline examination. The incidence of coronary events (i.e. fatal or non-fatal myocardial infarction), ischaemic stroke and cardiovascular events (i.e. myocardial infarction, ischaemic stroke or cardiovascular death) was studied over 18 years of follow-up. Results Adjusted for age, C3 in the fourth quartile (versus the first quartile) was associated with an increased incidence of coronary events [relative risk (RR) 1.54, 95% confidence interval (CI) 1.2-1.91, cardiovascular events (RR 1.56, 95% CI 1.3-1.9), and non-significantly with the incidence of ischaemic stroke (RR 1.31, 95% CI 0.89-1.8). However, after adjustments for smoking, body mass index (BMI), cholesterol, diabetes and systolic blood pressure, these relationships were completely attenuated and non-significant. The relationships were similar for C4 concentrations within the normal range. However, for men with C4 in the top 10% of the distribution (>0.34 g/l), a significantly increased incidence of coronary events was found, which persisted after adjustments for risk factors. Conclusion C3 and C4 show substantial correlations with cardiovascular risk factors, including blood pressure, BMI, and lipids. This relationship accounts for the increased incidence of CVD in men with high C3 levels. However, very high C4 levels may be associated with the incidence of CVD, independently of traditional cardiovascular risk factors.

- Background To evaluate potential sex differences, this study aimed to investigate blood pressure and lipid control and other risk factors for cardiovascular disease in treated hypertensive (tHT) patients from primary healthcare. Design and methods This cross-sectional survey of tHT patients was carried out between 2002 and 2005 by 264 primary care physicians from Sweden who consecutively recruited 6537 tHT patients (48% men and 52% women) from medical records. Results tHT men more often reached the treatment goal for systolic/diastolic blood pressure, less than 140/90 mmHg, than tHT women (30 vs. 26%, P < 0.01). Men had lower systolic blood pressure than women, however, women had lower diastolic blood pressure and higher pulse pressure. More tHT women had total cholesterol >= 5.0 mmol/l than corresponding men (75 vs. 64% P < 0.001). Men more often had diabetes (25 vs. 20% P < 0.001), left ventricular hypertrophy (20 vs. 16% P < 0.001), and microalbuminuria (24 vs. 16% P < 0.001). Women were more often treated with diuretics (64 vs. 48%) and P-receptor blockers, (54 vs. 51%), and men more often treated with angiotensin-converting enzyme inhibitors (27 vs. 18%), calcium channel blockers (34 vs. 26%), and lipid-lowering drugs (34 vs. 29%). Conclusion A need still exists for more intensified treatment of elevated blood pressure and hypercholesterolemia, especially in women. In hypertensives of both sexes, smoking and other risk factors also need to be addressed to reduce the risk of cardiovascular disease.

- AIMS: The intention of this study is to investigate the relationship of the demands/control/strain model with hard coronary events in an epidemiological, prospective, multicenter, European study. METHODS AND RESULTS: Six cohorts (Brussels, Ghent, Lille, Barcelona, Goteborg and Malmo) from four European countries (Belgium, France, Spain and Sweden) consisting of 21 111 middle-aged male subjects participated between 1993 and 1996 in the baseline survey of the Job Stress, Absenteeism and Coronary Heart Disease in Europe (JACE) study. The Karasek strain model of psychological demands (five items)/control (nine items) was used. During a mean follow-up of 40 months 185 acute coronary events or coronary deaths were observed. Age-adjusted hazard ratios (HRs) for developing an acute coronary event were 1.46 [CI 95% confidence interval (1.08-1.97)] for high against low psychological demands and 1.53 (95% CI 1.0-2.35) for strained (high demands plus low control) against relaxed (low demands plus high control) groups. After adjustment for standard cardiovascular risk factors the HR for developing a coronary event for those above or equal to the median against those below the median of psychological demands was 1.46 (95% CI 1.08-1.97) whereas the HR for strained against relaxed groups is 1.46 (95% CI 0.96-2.25). Sensitivity analyses confirmed the robustness of the results. CONCLUSION: In this European, multicenter, prospective, epidemiological study the Karasek job strain model was an independent predictor of acute coronary events, with the psychological demands scale emerging as the important component.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Few earlier studies have analysed smoking as a risk factor for myocardial infarction (MI) or stroke in type 2 diabetic patients. DESIGN AND METHODS: A longitudinal study involved 13 087 female and male patients with type 2 diabetes from the Swedish National Diabetes Register with no previous MI or stroke at baseline, aged 30-74 years, and with data available for all analysed variables, followed up for mean 5.7 years. RESULTS: Adjusted hazard ratios (HRs) for smoking and first-incident fatal/nonfatal MI, stroke and total mortality were 1.7 [95% confidence interval (CI): 1.4-2.0; P<0.001], 1.3 (95% CI: 1.1-1.6; P = 0.006) and 1.8 (95% CI: 1.5-2.2; P<0.001), respectively, by Cox regression analysis, adjusted for age, sex, diabetes duration, hypoglycaemic treatment, haemoglobin A1c, blood pressure, body mass index, microalbuminuria, antihypertensive and lipid-lowering drugs. Adjusted HR was higher for fatal MI, 2.1 (95% CI: 1.7-2.7; P<0.001), than for nonfatal MI, 1.4 (95% CI: 1.2-1.7; P<0.001). The highest HRs were observed in more frequently smoking (22%), middle-aged patients (age <60 years) for fatal/nonfatal MI, 2.3 (95% CI: 1.8-3.1; P<0.001) and for total mortality, 2.5 (95% CI: 1.6-3.8, P<0.001), whereas lower HRs were observed in older and less smoking patients. With predicted cessation of smoking in patients aged below 60 years, 24% (95% CI: 15-33%) of cases of fatal/nonfatal MI and 24% (11-37%) of cases of total mortality may have been prevented. CONCLUSION: The risk for MI and total mortality associated with smoking is high in type 2 diabetes, especially in more frequently smoking, middle-aged patients, and was higher for MI than for stroke, and also higher for fatal than for nonfatal events. Smoking cessation would strongly affect risk reduction.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: As cardiovascular disease (CVD) is one of the most common causes of mortality worldwide, much interest has been focused on reliable methods to predict cardiovascular risk.DESIGN: A cross-sectional, population-based screening study with 17-year follow-up in Southern Sweden.METHODS: We compared a non-laboratory, consultation-based risk assessment method comprising age, sex, present smoking, prevalent diabetes or hypertension at baseline, blood pressure (systolic >/=140 or diastolic >/=90), waist/height ratio and family history of CVD to Systemic COronary Risk Evaluation (SCORE) and a third model including several laboratory analyses, respectively, in predicting CVD risk. The study included clinical baseline data on 689 participants aged 40-59 years without CVD. Blood samples were analyzed for blood glucose, serum lipids, insulin, insulin-like growth factor-I, insulin-like growth factor binding protein-1, C-reactive protein, asymmetric dimethyl arginine and symmetric dimethyl arginine. During 17 years, the incidence of total CVD (first event) and death was registered.RESULTS: A non-laboratory-based risk assessment model, including variables easily obtained during one consultation visit to a general practitioner, predicted cardiovascular events as accurately [hazard ratio (HR): 2.72; 95% confidence interval (CI): 2.18-3.39, P<0.001] as the established SCORE algorithm (HR: 2.73; 95% CI: 2.10-3.55, P<0.001), which requires laboratory testing. Furthermore, adding a combination of sophisticated laboratory measurements covering lipids, inflammation and endothelial dysfunction, did not confer any additional value to the prediction of CVD risk (HR: 2.72; 95% CI: 2.19-3.37, P<0.001). The c-statistics for the consultation model (0.794; 95% CI: 0.762-0.823) was not significantly different from SCORE (0.767; 95% CI: 0.733-0.798, P=0.12) or the extended model (0.806; 95% CI: 0.774-0.835, P=0.55).CONCLUSION: A risk algorithm based on non-laboratory data from a single primary care consultation predicted long-term cardiovascular risk as accurately as either SCORE or an elaborate laboratory-based method in a defined middle-aged population.

- Background: Guidelines for the prevention of coronary artery disease (CAD) have been developed both in Europe and in the USA. However, several surveys have shown that these guidelines are poorly implemented in clinical practice. Design/methods: The Swedish Quality Control Programme on Secondary Prevention of CAD includes patients after myocardial infarction, or having undergone coronary artery surgery or percutaneous coronary intervention. Fifty of Sweden's 79 hospital districts are currently participating. Patients are asked to send report-cards regarding risk factor management to a central registry after discharge from hospital, at a 3-6 month visit and then yearly for 5 years. Results: Results based on data from 1 year after the index event show that a majority of patients reach targets for serum cholesterol (70%), and low-density lipoprotein (LDL)-cholesterol (71%). Mean value for total cholesterol is 4.6 (± SD 0.9) mmol/l, LDL-cholesterol 2.7 (± SD 0.8) mmol/l. Blood pressure targets are less often achieved, with 58% reaching the European Society of Cardiology target for systolic (< 140 mmHg) and 81% for diastolic (< 90 mmHg) blood pressure. A large proportion of patients are prescribed preventive drugs: aspirin (96%), beta-blockers (78%) and lipid-lowering drugs (83%). Conclusions: The Swedish Quality Control Programme is one of the first attempts to assess implementation of guidelines on a national level based on patient participation. It is hoped that shared care programmes and increased patient involvement with feedback on achieved treatment goals in relation to guidelines will improve outcomes in patients with CAD. © 2004 The European Society of Cardiology.
