- Background: The W allele of the G460W polymorphism in the adducin-1 gene has been occasionally associated with increased blood pressure (BP). The aim of this study was to test whether the G460W variant is associated with BP levels and BP progression rate and whether G460W associations with BP are affected by sex, body mass index (BMI), or age. Methods: The G460W polymorphism was genotyped in the population-based Malmo Diet and Cancer-cardiovascular arm (MDC-CVA; n = 6103), of whom 53% had also been examined 11 +/- 4.4 years earlier in the Malmo Preventive Project (MPP). Results: Among subjects without antihypertensive treatment (AHT) in the MDC-CVA (n = 5009), there was no difference between carriers (38%) and noncarriers (62%) of the W allele in systolic BP (139.2 +/- 18.2 v 139.2 +/- 18.5 mm Hg; P = .99) or diastolic BP (85.9 +/- 9.1 v 86.1 +/- 9.2 mm Hg; P = .49). In subjects free from AHT in the MPP and MDC (n = 2637) there was no difference between carriers (38%) and noncarriers (62%) in progression of systolic BP (2.0 +/- 2.5 v 2.0 +/- 2.7 mm Hg/year; P = .45) or diastolic BP (0.59 +/- 1.6 v 0.56 +/- 1.5 mm Hg/year; P = .66) from MPP to MDC. At MDC-CVA BP was influenced by interaction between the G460W and BMI (P = .02 for systolic BP and P = .002 for diastolic BP) and by interaction between G460W and sex (P = .03 for systolic BP and P = .02 for diastolic BP), a result further confirmed by stratified analysis showing that female carriers of the W allele belonging to the upper tertile of BMI had increased systolic BP (146.1 +/- 18.6 v 141.2 +/- 18.6 mm Hg; P < .001), diastolic BP (88.7 +/- 8.7 v 86.1 +/- 8.7 mm Hg; P < .001), and prevalence of hypertension (72.5% v 61.8 %; P = .001). Conclusions: Our data suggest that the G460W polymorphism influences BP when BMI and sex are taken into account.

- Background: Blunted nocturnal blood pressure dipping (NBPD) as well as high variability in blood pressure (BPV) and low variability in heart rate (HRV), are associated with increased cardiovascular morbidity and mortality. The aim of this study was to determine whether these traits are heritable. Methods: We studied 260 healthy siblings without antihypertensive drugs from 118 Swedish families. The BPV and HRV were defined as the standard deviation of BP and heart rate values recorded during 24 h, daytime (6 AM to 10 Pm), and night-time (10 Pm to 6 AM). The NBPD was defined as the ratio between night-time and daytime BP. Heritability was estimated with a maximal likelihood method implemented in the Solar software package with and without adjustment for significant covariates. Results: At night, significant heritability was found for systolic (33%, P <.05), diastolic (36%, P <.05), and mean (42%, P <.01) BPV. After covariate adjustment the corresponding heritability values were 23% (P =.08), 29% (P <.05), and 37% (P <.05). Daytime BPV was not heritable. The heritability of NBPD was 38% (P <.05) for systolic, 9% (P =.29) for diastolic, and 36% (P <.05) for mean BP, but after adjustment only systolic NBPD was significant (29%, P <.05). Heart rate was highly heritable both during daytime (57%, P <.001) and night-time (58%, P <.001), but the variability of heart rate, after adjustment, was only significant at night (37%, P <.05). Conclusions: Our data suggest that BPV and HRV are partially under genetic control and that genetic loci of importance for these traits could be mapped by linkage analysis.

- BackgroundThe presence of orthostatic hypotension (OH) predicts all-cause mortality and incident cardiovascular disease. Whether or not OH is associated with the development of heart failure (HF) remains unknown.MethodsIn this Swedish population-based prospective study (the Malmö Preventive Project), the incidence of HF in relation to baseline OH, defined as decrease in systolic (SBP) >/=20 mm Hg and/or diastolic blood pressure (DBP) >/=10 mm Hg upon standing, was studied in 32,669 middle-aged individuals (68.2% men; mean age, 45.6 +/- 7.4 years) over a mean follow-up period of 24 years.ResultsAt baseline, 1,991 (6.1%) participants were found to have OH. During follow-up, 1,293 persons (4.0%, mean age at presentation: 67.9 +/- 7.9 years) were hospitalized for HF, 912 (2.8%) of whom without previous or concurrent myocardial infarction (MI) ("nonischemic HF"). Among those who had OH, the corresponding numbers were 6.5% (n = 129) and 4.6% (n = 92), respectively. In multivariable Cox proportional hazard models, taking conventional HF risk factors into account, OH was associated with both all-cause and "nonischemic" HF events (hazard ratio (HR): 1.22, 1.01-1.46, and 1.31, 1.05-1.63, respectively). The association between OH and HF was more pronounced in younger (aged <45 years) than older individuals (2.05; 1.31-3.22 vs. 1.12, 0.92-1.38, respectively, P < 0.001 for interaction between age and OH on incident HF).ConclusionsThe presence of OH among middle-aged adults predicts long-term incidence of HF hospitalizations independently of conventional risk factors. Our findings add to the available data indicating that OH is a potential independent cardiovascular risk factor, especially with regard to younger individuals and nonischemic HF.American Journal of Hypertension (2010). doi:10.1038/ajh.2010.150.

- BACKGROUND: Women with a history of hypertensive disorders of pregnancy (HDP) are at increased risk of hypertension, cardiovascular disease, and type 2 diabetes. Offspring from pregnancies complicated by HDP also have worse cardiometabolic status in childhood and young adulthood, but the offspring risk of clinical hypertension in adulthood is largely unknown.METHODS: We studied 13,893 first-born adult offspring (49.4% female) who attended a structured population-based primary care visit (The Västerbotten Health Survey) at age 40 years in Sweden between 1994 and 2013. Data on maternal HDP were collected from a population-based birth register. We investigated the association between maternal HDP and the risk of adult offspring hypertension and worse cardiometabolic risk factor status utilizing multivariable poisson and linear regression models. We also conducted a sibling comparison, which inherently accounted for familial factors shared by siblings (N = 135).RESULTS: Offspring participants of women with HDP (N = 383, 2.8%) had increased relative risk of hypertension (1.67, 95% confidence interval: 1.38, 2.01) and also higher mean body mass index, systolic blood pressure, diastolic blood pressure, and worse 2-hour 75 g oral glucose tolerance test result at age 40 years. No difference was observed for serum cholesterol. Point estimates for the cardiometabolic risk factors were attenuated in the sibling analyses.CONCLUSION: Offspring born to mothers with a history of HDP are on an adverse cardiometabolic trajectory and should be considered as concomitant targets for primordial prevention of hypertension in the maternal post-pregnancy period.
