  • Interaction of apolipoprotein E genotype with smoking and physical inactivity on coronary heart disease risk in men and women.
  • 2012
  • Ingår i: Atherosclerosis. - 1879-1484. ; 220:2
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: Apolipoprotein E genotype (APOE) polymorphism affects lipid levels and coronary heart disease (CHD) risk. However, these associations may be modified by lifestyle factors. Therefore, we studied whether smoking, physical inactivity or overweight interact with APOE on cholesterol levels and CHD risk. METHODS: Combining two Swedish case-control studies yielded 1735 CHD cases and 4654 population controls (3747 men, 2642 women). Self-reported questionnaire lifestyle data included smoking (ever [current or former regular] or never) and physical inactivity (mainly sitting leisure time). We obtained LDL cholesterol levels and APOE genotypes. CHD risk was modelled using logistic regression to obtain odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for relevant covariates. RESULTS: Smoking interacted with APOE on CHD risk; adjusted ORs for ever versus never smoking were 1.45 (95% CI 1.00-2.10) in ɛ2 carriers, 2.25 (95% CI 1.90-2.68) in ɛ3 homozygotes and 2.37 (95% CI 1.85-3.04) in ɛ4 carriers. Female ɛ4 carriers had OR 3.62 (95% CI 2.32-5.63). The adjusted ORs for physical inactivity were 1.09 (95% CI 0.73-1.61), 1.34 (95% CI 1.12-1.61), and 1.79 (95% CI 1.38-2.30) in ɛ2, ɛ3ɛ3 and ɛ4 groups, respectively. No interaction was seen between overweight and APOE for CHD risk, or between any lifestyle factor and APOE for LDL cholesterol levels. CONCLUSION: The APOE ɛ2 allele counteracted CHD risk from smoking in both genders, while the ɛ4 allele was seen to potentiate this risk mainly in women. Similar ɛ2 protection and ɛ4 potentiation was suggested for CHD risk from physical inactivity.

  • The association between plasma homocysteine and coronary heart disease is modified by the MTHFR 677C>T polymorphism.
  • 2013
  • Ingår i: Heart (British Cardiac Society). - 1468-201X. ; 99:23, s. 1761-1765
  • Tidskriftsartikel (refereegranskat)abstract
    • An elevated level of total plasma homocysteine (tHcy) has been associated with risk of coronary heart disease (CHD). The level of tHcy is affected by lifestyle, in addition to genetic predisposition. The methylene tetrahydrofolate reductase (MTHFR) 677C>T polymorphism (rs1801133) is among the strongest genetic predictors of tHcy. We examined whether the association between tHcy and CHD is modified by the MTHFR 677C>T polymorphism.

  • Apolipoprotein C-I genotype and serum levels of triglycerides, C-reactive protein and coronary heart disease
  • 2010
  • Ingår i: Metabolism. - 0026-0495. ; 59:12, s. 1736-1741
  • Tidskriftsartikel (refereegranskat)abstract
    • Apolipoprotein C-I (apoCI) is implicated in lipid metabolism and inflammatory response, both important risk factors for human heart disease. However, most findings come from in vitro or animal studies, whereas data on human apoCI are sparse. To elucidate the role of apoCI in human disease, we analyzed a functional polymorphism in the promoter region of the apoCI gene in relation to blood lipids, C-reactive protein (CRP), coronary artery disease (CAD), and myocardial infarction (MI). Rs11568822 is a 4-base pair insertion/deletion (Ins/Del) polymorphism, and the Ins allele leads to a higher transcription in vitro compared with the Del allele. This polymorphism was analyzed in the Intergene study, a case-control study for CAD (N = 1236), and the Stockholm Heart Epidemiology Program, a case-control study for MI (N = 2774). Subjects homozygous for the Ins genotype had significantly higher serum levels of triglycerides (P = .01 and P = .006) and lower serum levels of CRP (P = .02 and P < .0001) compared with all other subjects in both studies. Similar results were obtained when analyzing only the controls of both studies (P = .002 and P = .0002, triglycerides; P = .002 and P < .0001, CRP). However, apoCI was not associated with CAD or MI. In conclusion, our data show that apoCI genotype is associated with serum levels of triglycerides and CRP, confirming the role of apoCI in lipid metabolism and suggesting that it also influences inflammation.

  • Comparison of Apolipoprotein (apoB/apoA-I) and Lipoprotein (Total Cholesterol/HDL) Ratio Determinants. Focus on Obesity, Diet and Alcohol Intake.
  • 2012
  • Ingår i: PloS one. - 1932-6203. ; 7:7
  • Tidskriftsartikel (refereegranskat)abstract
    • The ratio between apolipoprotein B and apolipoprotein A-I (apoB/apoA-I) has been suggested to be a powerful and more accurate predictor of future cardiovascular disease risk than total cholesterol and HDL cholesterol. Since diet and lifestyle can directly influence dyslipidemia, it is of interest to identify modifiable factors that are associated with high levels of the apolipoprotein ratio and if they can have a different association with a more traditional indicator of cardiovascular risk such as total cholesterol/HDL. The relationship between obesity and dyslipidemia is established and it is of interest to determine which factors can modify this association. This study investigated the cross-sectional association of obesity, diet and lifestyle factors with apoB/apoA-I and total cholesterol/HDL respectively, in a Swedish population of 2,907 subjects (1,537 women) as part of the INTERGENE study. The apolipoprotein and lipoprotein ratios were highly correlated, particularly in women, and obesity was strongly associated with both. Additionally, age, cigarette smoking and alcohol intake were important determinants of these ratios. Alcohol was the only dietary factor that appreciably attenuated the association between obesity and each of the ratios, with a stronger attenuation in women. Other dietary intake and lifestyle-related factors such as smoking status and physical activity had a lower effect on this association. Because the apolipoprotein and lipoprotein ratios share similar diet and lifestyle determinants as well as being highly correlated, we conclude that either of these ratios may be a sufficient indicator of dyslipidemia.

  • Midlife homocysteine and late-life dementia in women. A prospective population study.

    • Elevated serum total homocysteine (tHcy) is an established risk factor for cardiovascular disease. Its role in dementia is still controversial, and no study has examined the role of midlife tHcy, or reports longer than 8 years of follow-up. We examined the relation between midlife tHcy and late-life dementia in women followed for 35 years. The Prospective Population Study of Women in Gothenburg began in 1968-1969, comprising a representative population of women aged 38-60 years. Four extensive follow-ups were conducted by 2003. Serum samples from 1968 to 1969 were analysed for tHcy in 1368 women. In total, 151 women developed dementia. The highest tHcy tertile was related to a hazard ratio of 1.7 (95% CI 1.1-2.6) for developing any dementia, 2.1 (95% CI 1.2-3.7, n=100) for AD and 2.4 (95% CI 1.3-4.7, n=68) for AD without cerebrovascular disease. Kaplan-Meier plots showed divergence with respect to dementia after 22 years of follow-up. In conclusion, high homocysteine in midlife is an independent risk factor for the development of late-life Alzheimer dementia in women.
