- Cardiopulmonary diseases are major causes of death worldwide, but currently recommended strategies for diagnosis and prevention may be outdated because of recent changes in risk factor patterns. The Swedish CArdioPulmonarybioImage Study (SCAPIS) combines the use of new imaging technologies, advances in large-scale 'omics' and epidemiological analyses to extensively characterize a Swedish cohort of 30 000 men and women aged between 50 and 64 years. The information obtained will be used to improve risk prediction of cardiopulmonary diseases and optimize the ability to study disease mechanisms. A comprehensive pilot study in 1111 individuals, which was completed in 2012, demonstrated the feasibility and financial and ethical consequences of SCAPIS. Recruitment to the national, multicentre study has recently started.

- Background Calcium antagonists are a first-line treatment for hypertension. The effectiveness of diltiazem, a nondihydropyridine calcium antagonist, in reducing cardiovascular morbidity or mortality is unclear. We compared the effects of diltiazem with that of diuretics, beta-blockers, or both on cardiovascular morbidity and mortality in hypertensive patients. Methods In a prospective, randomised, open, blinded endpoint study, we enrolled 10 881 patients, aged 50-74 years, at health centres in Norway and Sweden, who had diastolic blood pressure of 100 mm Hg or more. We randomly assigned patients diltiazem, or diuretics, beta-blockers, or both. The combined primary endpoint was fatal and non-fatal stroke, myocardial infarction, and other cardiovascular death. Analysis was done by intention to treat. Findings Systolic and diastolic blood pressure were lowered effectively in the diltiazem and diuretic and beta-blocker groups (reduction 20.3/18.7 vs 23.3/18.7 mm Hg, difference in systolic reduction p<0.001). A primary endpoint occurred in 403 patients in the diltiazem group and in 400 in the diuretic and beta-blocker group (16.6 vs 16.2 events per 1000 patient-years, relative risk 1.00 [95% CI 0.87-1.15], p=0.97). Fatal and non-fatal stroke occurred in 159 patients in the diltiazem group and in 196 in the diuretic and beta-blocker group (6.4 vs 7.9 events per 1000 patient-years, 0.80 [0.65-0.99], p=0.04) and fatal and non-fatal myocardial infarction in 183 and 157 patients (7.4 vs 6.3 events per 1000 patient-years, 1.16 [0.94-1.44], p=0.17). Interpretation Diltiazem was as effective as treatment based on diuretics, beta-blockers, or both in preventing the combined primary endpoint of all stroke, myocardial infarction, and other cardiovascular death.

- Background The aim of the Nordic Diltiazem (NORDIL) Study was to compare patients with essential hypertension receiving calcium-antagonist-based treatment with diltiazem and similar patients receiving conventional diuretic/beta-blocker-based treatment, with respect to cardiovascular morbidity and mortality. Objective To assess the influence of age, sex, severity of hypertension and heart rate on treatment effects, in a sub-analysis. Methods The NORDIL study was prospective, randomized, open and endpoint-blinded. It enrolled, at health centres in Norway and Sweden, 10881 patients aged 50-74 years who had diastolic blood pressure (DBP) of 100 mmHg or more. Systolic blood pressure (SBP) and DBP were decreased by 20.3/18.7 mmHg in the diltiazem group and by 23.3/18.7 mmHg in the diuretic/beta-blocker group - a significant difference in SBP (P < 0.001). Results The incidence of the primary endpoint - a composite of cardiovascular death, cerebral stroke and myocardial infarction - was similar for the two treatments. Fatal and non-fatal stroke occurred in 159 patients in the diltiazem group and in 196 patients in the conventional treatment group [relative risk MR) 0.80, 95% confidence interval (CO 0.65 to 0.99, P = 0.0401, whereas there was a non-significant inverse tendency with respect to all myocardial infarction. Three Were significantly fewer cerebral strokes ip atiepts receiving diltiazem in the subgroups with baseline SBP > 170 mmHg (n = 5420, RR 0.75,95% CI 0.58 to 0.98, P = 0.032), DBP 105 mmHg (n = 5881, RR 0.74,95% Cl 0.57 to 0.97, P = 0.030) and pulse pressure greater than or equal to 66 mmHg (n = 5461, RR 0.76, 95% Cl 0.58 to 0.99, P = 0.041), and more myocardial infarctions in those with heart rate less than 74 beats/min (n = 5303, RR 1.13, 95% Cl 1.01 to 1.87, P = 0.040). However, the tendencies for fewer strokes and greater incidence of myocardial infarction were present across subgroups when results were analysed for age, sex, severity of hypertension and heart rate, and treatment-subgroup interaction analyses were not statistically significant. Conclusions Compared with a conventional diuretic/beta-blocker-based anti hypertensive regimen, there were additional 25% reductions in stroke in the diltiazem-treated patients with blood pressure or pulse pressure greater than the medians, and an increase in myocardial infarction in those with heart rate less than the median. Such findings may be attributable to chance, but the consistency of, in particular, the stroke findings may also suggest an ability of diltiazem, beyond conventional treatment, to prevent cerebral stroke in hypertensive patients with the greatest cardiovascular risk.

- Objectives. A common nonsynonymous single nucleotide polymorphism (SNP) in the CD93 gene (rs3746731, Pro541Ser) has been associated with risk of coronary artery disease (CAD). CD93 is a transmembrane glycoprotein, which is detectable in soluble form in human plasma. We investigated whether the concentration of soluble CD93 in plasma is related to risk of myocardial infarction (MI) and CAD, using a case-control study of premature MI (n = 764) and a nested case-control analysis of a longitudinal cohort study of 60-year-old subjects (analysis comprising 844 of 4232 subjects enrolled at baseline). In addition, SNPs in the CD93 gene were studied in relation to plasma CD93 concentration and CD93 mRNA expression. Methods and Results. A sensitive and specific enzyme-linked immunosorbent assay was established for determination of the plasma CD93 concentration. Subjects were divided into three groups according to tertiles of the distribution of CD93 concentration. Lower odds ratios for risk of MI and incidence of CAD were observed in the middle CD93 tertile (142-173 mu g L(-1)): odds ratio (95% confidence interval), 0.69 (0.49-0.97) and 0.61 (0.40-0.94), respectively. These associations were independent of traditional CAD risk factors. The minor allele of a SNP in the 3' untranslated region of CD93(rs2749812) was associated with increased plasma CD93 concentrations (P = 0.03) and increased CD93 mRNA expression levels (P = 0.02). Conclusion. The results of the present study suggest that the concentration of soluble CD93 in plasma is a potential novel biomarker for CAD, including MI.
