- Objective Incidence of cardiovascular disease (CVD) is higher in men than in women. The aim of this study was to investigate whether the gender differential can be modified by pharmacological intervention in a population-based setting. Design and method In a prospective population-based cohort - the Malmo Diet and Cancer study - a total of 3608 hypertensives (1559 men, 2049 women), 45-73 years old, with a mean of 10 years' treatment at baseline examination, participated in the study. Information on blood pressure-lowering medication was collected in a questionnaire. Incidences of first-ever cardiac event, stroke or CVD death were followed. The mean period of follow-up was 7.4 years. Results During follow-up, 341 first-ever CVD events and 128 CVD deaths occurred. The risk of CVD morbidity or mortality was significantly higher in hypertensive men than in hypertensive women: cardiac event [relative risk (RR) = 3.11; 95% confidence interval (CI): 2.13 - 4.54], stroke (RR U 1.50; 95% CI: 1.01 - 2.22) and CVD death (RR = 2.96; 95% CI: 1.86 - 4.20). However, the gender gap in CVD risks was reduced with advancing age. Two background factors - single household and concomitant diabetes - are apt to have an independent sex-specific impact on CVD risk. Conclusions Gender remains a strong independent predictor for CVD morbidity and mortality, irrespective of antihypertensive intervention or other risk factors. Increased clinical attention should be given to hypertensive men living alone and hypertensive women with diabetes.

- OBJECTIVE: Serum and glucocorticoid regulated kinase 1 (SGK1) expression is increased by aldosterone and is a key regulator of the amiloride-sensitive sodium channel (ENaC) in the distal nephron. We have previously shown that two SNPs in SGK1 (rs1057293 and rs1743966) are associated with blood pressure variation and blood pressure progression in the general population. Therefore, we tested the association of these variants with ischaemic stroke. METHODS: Using logistic regression, we analysed rs1057293 and rs1743966 for association with ischaemic stroke in two independent age-matched and sex-matched case-control groups from the twin cities of Lund (cases n = 1837 and controls n = 947) and Malmö (cases n = 888 and controls n = 893) in the Scania region of southern Sweden. RESULTS: In additive models adjusted for hypertension, smoking and diabetes, the major allele (G) of rs1057293 was associated (odds ratio, 95% confidence interval; P value) with ischaemic stroke with similar effect size in both studies; in Lund (1.35, 1.11-1.64; P = 0.002) and Malmö (1.30, 1.03-1.65; P = 0.027). When the two studies were pooled, the overall association was 1.32, 1.14-1.52; P < 0.001. The major allele of rs1743966 (A), which was in linkage disequilibrium with rs1057293, showed a similar trend as rs1057293 G-allele but with slightly weaker effect size and P value. CONCLUSION: In two independent but ethnically similar populations, we observed an association between genetic variants in SGK1 and ischaemic stroke. Interestingly, the association seems to be at least partially independent of blood pressure. This could imply that cerebrovascular ENaC or other SGK1-regulated proteins may be of importance for development of ischaemic stroke.

- BACKGROUND: Although age is associated with increasing blood pressure, there is a substantial heterogeneity within a certain birth cohort. Whether increase in systolic and diastolic blood pressure is related to pulmonary function is largely unknown. OBJECTIVE: To study blood pressure elevation between 55 and 68 years of age in relation to vital capacity (VC) and forced expiratory volume (FEV1.0) at 55. DESIGN: Population-based cohort study. PARTICIPANTS: A total of 375 men without antihypertensive medication at baseline. MAIN OUTCOME MEASURE: Change in systolic blood pressure (SBP) and diastolic blood pressure (DBP) over 13 years. RESULTS: Blood pressure increase between 55 and 68 years was highest among men who at 55 years had low vital capacity. Average increase in systolic blood pressure for men with vital capacity in the first, second, third and fourth quartile was 20.4, 18.7, 16.5 and 11.1 mmHg, respectively (P for trend = 0.005). Average increase in diastolic blood pressure was 10.6, 9.9, 9.0 and 6.3 mmHg, respectively (P= 0.02). The trends remained statistically significant after adjustments for baseline blood pressure, tobacco consumption, smoking cessation between 55 and 68, weight change between 55 and 68, physical activity and diabetes. Further analysis showed that the relationships could be found among men with blood pressures < or = 140/ 90 mmHg at baseline, whereas no significant association was found for men whose baseline SBP or DBP exceeded 140/90 mmHg. FEV1.0 showed similar associations with change in blood pressure. CONCLUSION: Lung function is inversely associated with future blood pressure increase. It is suggested that this association could contribute to the relationships between lung function and incidence of cardiovascular disease.

- BACKGROUND AND OBJECTIVE: Although hypertension is associated with increased cardiovascular risk, many individuals remain free from disease. This study is aimed to investigate whether this variation in individual susceptibility is associated with lung function. DESIGN: Population-based prospective cohort study. PARTICIPANTS: 'Men born in 1914', Malmo, Sweden. Subjects (n = 639) were examined and considered free from prevalent cardiovascular disease at age 55 years. MAIN OUTCOME MEASURES: Mortality, fatal and non-fatal stroke and cardiac events (fatal or non-fatal myocardial infarction) during 28-years follow-up. RESULTS: Of the men, 467 had normal blood pressure and 172 (27%) had hypertension (> or = 160/95 mmHg or treatment for hypertension). Hypertensive men with height-adjusted forced expiratory volume during 1 s (FEV1.0) below median had significantly higher rates of stroke (13.4 versus 5.8/1,000 person-years), cardiac events (27.1 versus 12.8/1,000 person-years) and all cause mortality (52.5 versus 28.6/1,000 person-years) than hypertensive men with high FEV1.0. These differences remained statistically significant after adjustment for potential confounders. Men with normal blood pressure and FEV1.0 below median had higher rates of stroke (5.4 versus 4.2/1,000 person-years), cardiac events (13.3 versus 11.6/1,000 person-years) and all cause mortality (29.9 versus 21.2/1,000 person-years) than men with normal blood pressure and high FEV1.0. After adjustments for potential confounders, FEV1.0 was significantly associated with mortality among men with normal blood pressure, whereas the associations with stroke and cardiac events did not reach significance. CONCLUSION: The incidence of cardiovascular disease and death associated with hypertension is increased among men with reduced lung function. The synergistic interaction between hypertension and lung function was independent of smoking and other potential confounders.

- A recently published genome wide association study identified 29 single nucleotide polymorphisms (SNPs) influencing blood pressure (BP). Case-control studies suggest that a genetic risk score (GRS) based on these 29 SNPs affect the risk of cardiovascular disease (CVD), but its role for CVD at population level is unknown. Here, we prospectively evaluate the impact of this polygenetic BP component on CVD morbidity and mortality in a large urban-based middle-aged population.

- BACKGROUND: As recently pinpointed by a genome-wide association study the serine/threonine kinase 39 (STK39) is a candidate gene for hypertension. This kinase is strongly implicated in sodium reabsorption by the kidney through its modulating effect on furosemide-sensitive and thiazide-sensitive channels. The aim of our study was to test the effects of the STK39 rs35929607A>G polymorphism on blood pressure (BP) levels and the prevalence and incidence of hypertension in middle-aged Swedes participating in two urban-based surveys in Malmö (Sweden). METHODS: The rs35929607A>G polymorphism was genotyped in 5634 participants included in the cardiovascular cohort of the 'Malmö Diet and Cancer-cardiovascular arm' (MDC-CVA) study and successively in 17 894 participants of the 'Malmö Preventive Project' (MPP) both at baseline and at reinvestigation after a mean of 23 years. The effect of the same single nucleotide polymorphism on salt sensitivity was tested in 39 participants of the Salt Reduction to Avoid Hypertension study. RESULTS: Both before and after adjustment for covariates, the functional rs35929607A>G polymorphism was associated with higher SBP and DBP values in the MDC-CVA, but not in the MPP. In both surveys, the polymorphism was associated with hypertension prevalence; after adjustment using the autosomal-dominant model, the odds ratio for hypertension ranged between 1.077 (MPP at baseline) and 1.151 (MDC-CVA) with P-value less than 0.05. After stratification for sex, the results remained statistically significant in women, but not in men. Carriers of the G-allele displayed an increase in salt sensitivity. CONCLUSION: Our results from two large cohort studies support previous evidence about the association of the STK39 rs35929607A>G variant with hypertension, especially in women. If further confirmed in successive studies, owing to its pivotal role in sodium reabsorption at the renal tubule level, STK39 might prove to be a suitable target for antihypertensive therapy. The greater effect of the STK39 rs35929607A>G polymorphism in women with respect to men deserves further investigation.
