Gallstone Disease and the Risk of Ischemic Heart Disease.

ABSTRACT: Gallstone disease (GSD) is related to multiple cardiovascular risk factors; the present study was to prospectively examine the association between GSD and ischemic heart disease (IHD).We examined the association of GSD with IHD among 199 292 men and 288 081 women aged 30-79 years in the China Kadoorie Biobank study. Participants with cancer, heart disease, and stroke at baseline were excluded. Cox proportional hazards regression model was used to estimate the association of GSD with IHD. The prevalence of self-reported GSD was 3.7% in men and 7.3% in women at baseline. During 3 431 124 person-years of follow-up between 2004 and 2013 (median, 7.2 years), we documented 10 245 incident IHD cases in men and 14 714 in women. As compared with men without GSD at baseline, the multivariate-adjusted hazard ratio for IHD was 1.11 (95% confidence interval, 1.02-1.22) for men with GSD; the respective hazard ratio was 1.27 (95% confidence interval, 1.20-1.34) in women and 1.23 (95% confidence interval, 1.17-1.28) in the whole cohort. The sex difference in IHD risk associated with GSD was statistically significant (P=0.009 for interaction with sex). In addition, we found that the association between GSD and IHD was stronger in nonhypertensive than in hypertensive women (P<0.001 for interaction).In this large prospective study, the presence of GSD was associated with an increased risk of incident IHD, independent of other risk factors of cardiovascular disease. Our findings suggest novel prevention strategy to mitigate heart disease through improvement of gastrointestinal health.

Project description:BackgroundWomen who deliver pre-term have been reported to have increased future risks of cardiometabolic disorders. However, their long-term risks of ischemic heart disease (IHD) and whether such risks are due to shared familial factors are unclear. A better understanding of these risks may help improve long-term clinical follow-up and interventions to prevent IHD in women.ObjectivesThe purpose of this study was to determine the long-term risks of IHD in women by pregnancy duration.MethodsA national cohort study was conducted of all 2,189,190 women with a singleton delivery in Sweden from 1973 to 2015, who were followed up for IHD through the end of 2015. Cox regression was used to compute adjusted hazard ratios (aHRs) for IHD associated with pregnancy duration, and cosibling analyses assessed the influence of shared familial (genetic and/or environmental) factors.ResultsIn 47.5 million person-years of follow-up, 49,955 (2.3%) women were diagnosed with IHD. In the 10 years following delivery, the aHR for IHD associated with pre-term delivery (<37 weeks) was 2.47 (95% confidence interval [CI]: 2.16 to 2.82), and further stratified was 4.04 (95% CI: 2.69 to 6.08) for extremely pre-term (22 to 27 weeks), 2.62 (95% CI: 2.09 to 3.29) for very pre-term (28 to 33 weeks), 2.30 (95% CI: 1.97 to 2.70) for late pre-term (34 to 36 weeks), and 1.47 (95% CI: 1.30 to 1.65) for early-term (37 to 38 weeks), compared with full-term (39 to 41 weeks). These risks declined but remained significantly elevated after additional follow-up (pre-term vs. full-term, 10 to 19 years: aHR: 1.86; 95% CI: 1.73 to 1.99; 20 to 29 years: aHR: 1.52; 95% CI: 1.45 to 1.59; 30 to 43 years: aHR: 1.38; 95% CI: 1.32 to 1.45). These findings did not appear attributable to shared genetic or environmental factors within families. Additional pre-term deliveries were associated with further increases in risk.ConclusionsIn this large national cohort, pre-term delivery was a strong independent risk factor for IHD. This association waned over time but remained substantially elevated up to 40 years later. Pre-term delivery should be recognized as a risk factor for IHD in women across the life course.

Project description:ImportancePreterm birth has previously been associated with increased risks of hypertension and diabetes, but not ischemic heart disease (IHD), in adulthood. The reasons for this lack of association with IHD despite associations with its risk factors have been elusive, but may be associated with methodologic issues, such as survivor bias, in prior studies.ObjectiveTo determine whether preterm birth is associated with an increased risk of IHD in adulthood in a large population-based cohort.Design, setting, and participantsThis national, population-based cohort study included all 2 141 709 persons who were born as singleton live births in Sweden during 1973 to 1994. The data were analyzed in September 2018.ExposuresGestational age at birth, identified from nationwide birth records in the Swedish Birth Registry.Main outcomes and measuresIschemic heart disease that was identified from nationwide inpatient and outpatient diagnoses through 2015 (maximum age, 43 years). A Cox regression was used to examine gestational age at birth in association with IHD in adulthood while adjusting for other perinatal and maternal factors. Cosibling analyses assessed for potential confounding by unmeasured shared familial factors.ResultsOf 2 141 709 participants, 1 041 906 (48.6%) were female and there were 1921 persons (0.09%) who received a diagnosis of IHD in 30.9 million person-years of follow-up. Gestational age at birth was inversely associated with IHD risk in adulthood. At ages 30 to 43 years, adjusted hazard ratios for IHD associated with preterm (gestational age <37 weeks) and early-term birth (37-38 weeks) were 1.53 (95% CI, 1.20-1.94) and 1.19 (1.01-1.40), respectively, compared with full-term birth (39-41 weeks). Preterm-born women had lower IHD incidence than preterm-born men (15.16 vs 22.00 per 100 000 person-years) but had a higher adjusted hazard ratio (1.93; 95% CI, 1.28-2.90 vs 1.37; 95% CI, 1.01-1.84). These associations did not appear to be explained by shared genetic or environmental factors in families.Conclusions and relevanceIn this large national cohort, preterm and early-term birth were associated with an increased IHD risk in adulthood. Persons born prematurely need early evaluation and preventive actions to reduce the risk of IHD.

Project description:BackgroundThe objective of this study was to evaluate whether modifiable cardiovascular risk conditions and lifestyle factors were temporally associated with an increased risk for ischemic heart disease and overall mortality in a cohort of hematopoietic cell transplantation (HCT) survivors.MethodsHCT recipients who had survived for ≥1 year, were ≥20 years old, and had undergone transplantation between 1970 and 2010 at a transplant referral center were surveyed in 2010-2011 about cardiovascular health and lifestyle factors (n = 3833). Respondents (n = 2360 [61.6%]) were followed to 2016 for incident ischemic heart disease and overall mortality.ResultsAmong the 2360 transplant survivors (median age at the baseline survey, 55.9 years; median time since transplantation, 10.8 years), 162 (6.9%) reported ischemic heart disease at the baseline survey. Among those without ischemic heart disease at the baseline survey (n = 2198), the 5-year cumulative incidence of subsequent ischemic heart disease was 4.3%. Obesity, dyslipidemia, diabetes, and physical inactivity at baseline were associated with an increased risk for subsequent ischemic heart disease (hazard ratio [HRs] ≥ 1.8). Greater physical activity and fruit/vegetable intake at baseline were associated with subsequent lower overall mortality (HRs ≤ 0.7). When jointly considered, each additional cardiovascular risk condition and each adverse lifestyle factor were independently associated with subsequent ischemic heart disease (HR for risk conditions, 1.4; 95% confidence interval [CI], 1.0-1.9; HR for lifestyle factors, 1.9; 95% CI, 1.2-2.9), and adverse lifestyle factors remained associated with overall mortality (HR, 1.8; 95% CI, 1.5-2.3).ConclusionsThese results support strong efforts to promote healthy lifestyle behaviors and to treat cardiovascular risk factors aggressively in HCT survivors. This may reduce future ischemic heart disease and overall mortality in this high-risk population. Cancer 2018;124:1507-15. © 2018 American Cancer Society.
