- BACKGROUND AND OBJECTIVE:Major risk factors for congestive heart failure (CHF) are myocardial infarction, hypertension, diabetes, atrial fibrillation, smoking, left ventricular hypertrophy (LVH) and obesity. However, since these risk factors only explain part of the risk of CHF, we investigated whether persistent organic pollutants (POPs) might also play a role.METHODS:In the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study, left ventricular ejection fraction, (EF), E/A-ratio and isovolumic relaxation time (IVRT), were determined by echocardiography and serum samples of 21 POPs were analyzed in serum measured by high-resolution chromatography coupled to high-resolution mass spectrometry (HRGC/HRMS) in 998 subjects all aged 70 years.RESULTS:In this cross-sectional analysis, high levels of several of the polychlorinated biphenyls (PCB congeners 99, 118, 105, 138, 153, and 180) and octachlorodibenzo-p-dioxin (OCDD) were significantly related to a decreased EF. Some POPs were also related to a decreased E/A-ratio (PCBs 206 and 209). All the results were adjusted for gender, hypertension, diabetes, smoking, LVH and BMI, and subjects with myocardial infarction or atrial fibrillation were excluded from the analysis.CONCLUSIONS:Circulating levels of POPs were related to impairments in both left ventricular systolic and diastolic function independently of major congestive heart failure risk factors, suggesting a possible role of POPs in heart failure.

- Background:Established risk factors for left ventricular hypertrophy (LVH) are hypertension, diabetes, and obesity. However, as these risk factors explain only part of the variation in left ventricular mass, we investigated whether persistent organic pollutants (POPs) might also play a role in LVH, because exposure to polychlorinated biphenyl 126 induced cardiac growth in rats.Methods:In the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS), left ventricular mass index (LVMI), relative wall thickness (RWT), and geometric groups of LVH, were determined by echocardiography and 21 POPs were measured by high-resolution chromatography coupled to high-resolution mass spectrometry (HRGC/HRMS) in 1016 individuals aged 70 years. All individuals with a history of myocardial infarction were excluded from analysis (n=72).Results:Several of the POPs were related to abnormal left ventricular geometry before adjustment for established risk factors, but lost in significance following adjustment. However, the pesticide hexachlorobenzene (HCB) levels were significantly related to RWT, and concentric left ventricular remodeling, also following adjustment for sex, blood pressure, antihypertensive treatment, diabetes, and BMI (Pandlt;0.0001).Conclusion:In this cross-sectional study, circulating levels of HCB were related to increased wall thickness of the left ventricle and concentric left ventricular remodeling, independently of LVH risk factors, suggesting a role of this environmental contaminant in abnormal growth of the left ventricle.
