Multiple lines of evidence suggest that fatty acid (FA) binding affinity, viscosity, and cellular membrane fluidity together may play important roles in cardiovascular pathophysiology. Conventional classifications also incompletely capture the wide heterogeneity of diverse FAs. Via a novel etiologic paradigm, we investigate the Lipophilic Index (LI) and risk of coronary heart disease (CHD). Prospective nested case-control study in a cohort of 32,826 U.S. women who provided baseline blood in 1989 –1990. During 6-years follow-up, 166 incident CHD cases were matched with 327 controls. Assaying full FA profiles via gas chromatography, 43 FAs were identified in plasma and erythrocytes. We developed a novel FA risk index based on molecular properties of fat lipophilicity, constructed upon FA melting points, and parameterized via individual weighted summation of melting points; the LI was constructed upon 32 unique FAs with official melting points. Among controls, mean (SD) lipophilicity was 16.8°C (2.48) for Plasma-LI and 17.1°C (1.5) for Erythrocyte-LI, r=0.54. In prospective analyses, increasing Plasma-LI and Erythrocyte-LI were strongly associated with greater risk of CHD in both crude and multivariable models: RR=3.56 (95%CI: 1.48 – 8.67, P-trend=0.001) for Plasma-LI, and RR=3.80 (1.12–12.9, P-trend=0.03) for Erythrocyte-LI, comparing extreme quintiles. Individuals with higher LI also exhibited adverse lipid profiles, hyperglycemia, hypertension, and endothelial dysfunction. Notably, higher Plasma-LI was associated with having low HDL<40mg/dl (OR per-SD=2.71, 1.91–3.84; P<0.0001), elevated triglycerides>=150mg/dl (OR=3.89, 2.83–5.35; P<0.0001), hypertension (OR=1.34, 1.07–1.66; P=0.009), elevated HbA1c>=6% (OR=1.50, 1.17–1.91; P=0.001), and highest quintile of E-selectin (OR=1.92, 1.47–2.50; P<0.0001). LI trends with CHD risk also persisted after adjustment for these metabolic risk factors, plus trans and total fat intakes. The Lipophilic Index of plasma and erythrocyte fatty acids is strongly associated with adverse metabolic profiles and higher risk of CHD development. Findings support a novel mechanism that fatty acid lipophilicity is important in CHD pathogenesis.

Introduction: Studies indicate dietary types of fats are associated with risk of coronary heart disease (CHD). Traditional broad classifications may incompletely capture the diversity of fatty acids on CHD. The novel lipid index Dietary Lipophilic Load (DLL) reflects a unique combination of fatty acid fluidity, intermolecular attraction, plus relative fat quantity, while Dietary Lipophilic Index (DLI) is a measure of average fat fluidity, regardless of fat quantity. Thus, we evaluated the association, DLL and DLI, with risk of incident CHD. METHODS: Participants included 30,932 women in the Women’s Health Study (WHS), who were free of major chronic diseases at baseline. DLL was calculated by weighted summation of the multiplicative product of each fatty acid’s intakes (g/day) and its melting points (Celcius); DLI was calculated by dividing DLL by total fat intake (g/day). Hazard ratios (HRs) were adjusted for established risk factors, with updated dietary data, and potential mediators. We also investigated hypothesized interactions with C-Reactive Protein (CRP). RESULTS: There were 1137 cases of incident CHD in 525,828 person-years over 19 years follow-up. At baseline in over 27,000 women with blood samples, DLL and DLI were not correlated with serum cholesterol, triglyceride, HbA1c, ICAM-1, or CRP biomarkers (r<0.02 for all). In overall multivariate analysis, DLL was associated with higher risk of CHD (extreme quintile HR=1.40, 95%CI: 1.11-1.76, P trend=0.0002), while DLI was not (HR=0.83, 95%CI: 0.67-1.03, P trend=0.75). DLL results were independent beyond adjustment for dietary trans, saturated, monounsaturated, and polyunsaturated fats, nor their aggregate adjustment or the P:S ratio. DLL effects persisted even adjusting for CRP (HR=1.29, P-trend=1 mg/dL for DLL (extreme quintile HR=1.38, 1.02-1.88), than among individuals with low CRP <1 mg/dl for DLL (HR=1.08, 0.68-1.72), with P-interaction<0.0001. Furthermore, CRP also modified DLI, where effects again diverged among higher CRP (HR=0.98, 0.73-1.31) versus low CRP (HR=0.45, 0.27-0.74), with P-interaction<0.0001. Moreover, adjustment of triglycerides, HbA1c, ICAM-1, LDL or HDL cholesterol also did not materially affect overall results. CONCLUSION: Results indicate that DLL is associated with increased risk of incident CHD, independent of traditional risk factors, conventional dietary fat classifications, and major CHD biomarkers. Effects of DLL and DLI appear to be modified by levels of CRP. DLL appears to be an important novel dietary fat index that captures additional CHD risk information beyond biomarkers and traditional dietary fat categories. Further studies are warranted.

AbstractAssociation between body mass index (BMI) and coronary heart disease (CHD) in cancer survivors is not clearly established. This study analyzed the prediagnosis BMI-CHD association by examining 13,500 cancer survivors identified from the National Health Insurance Service-Health Screening Cohort from January 1, 2004 to December 31, 2009 including the patients who were free of cardiovascular disease at enrollment. The Cox proportional hazards model (adjusted for socioeconomic, health behavior, health status, and medical characteristics) was used for calculating hazard ratios (HR) and 95% confidence intervals (95% CI) for CHD in each prediagnosis BMI category among cancer survivors. Compared to cancer survivors with a prediagnosis BMI between 18.5 and 22.9 kg/m2, those with a prediagnosis BMI of 23.0–24.9 kg/m2 and ≥ 25.0 kg/m2 had significantly higher CHD risk (HR = 1.51; 95% CI: 1.13–2.01 and HR = 1.38; 95% CI: 1.04–1.84, respectively). Cancer survivors with a low prediagnosis BMI (< 18.5 kg/m2) also had significantly higher CHD risk (HR = 1.97; 95% CI: 1.20–3.24) compared to those with a BMI of 18.5–22.9 kg/m2. Similar associations were found after stratifying analyses based on first cancer site and sociodemographic and medical characteristic subgroups. Our study suggests that prediagnosis underweight among patients with cancer is a predictor of CHD risk.

AbstractDuring the development of atherosclerotic lesion, s-RNYs (small RNAs of about 24/34 nucleotides) are derived by the processing of long Ro-associated non-coding RNAs (RNYs) in macrophages. The levels of serum s-RNYs have been found significantly upregulated in patients with coronary heart disease (CHD) compared to age-matched CHD-free individuals. The present study aimed to examine the predictive value of serum s-RNYs for CHD events in the general male population. Within the frame of nested-case–control study, the GENES study, we measured the absolute expression of a RNY-derived small RNA, the s-RNY1-5p, in the serum of individuals (without CHD at baseline) who encountered a CHD event within 12 years of follow-up (n = 30) (Cases) and compared them to individuals who remained event-free (Controls) (n = 30). The expression of s-RNY1-5p in serum was significantly upregulated in Cases compared to Controls (p = 0.027). The proportion of CHD event-free was significantly higher among individuals with serum s-RNY1-5p below the median value (631 molecules/mL). In a multivariable model adjusted for age, smoking, hypertension, diabetes and dyslipidemia, the risk of CHD events increased more than fourfold in individuals with serum s-RNY1-5p above the median value (HR, 4.36; 95% CI 1.22–15.60). A positive association with CHD events was also observed when considering s-RNY1-5p as a continuous variable (p = 0.022). Based on our results, we conclude that serum s-RNY1-5p is an independent predictor of CHD events in a general male population and might be a relevant biomarker for early detection of cardiovascular diseases.

At a workshop to update the science linking saturated fatty acid (SAFA) consumption with the risk of coronary heart disease (CHD) and ischemic stroke, invited participants presented data on the consumption and bioavailability of SAFA and their functions in the body and food technology. Epidemiological methods and outcomes were related to the association between SAFA consumption and disease events and mortality. Participants reviewed the effects of SAFA on CHD, causal risk factors, and surrogate risk markers. Higher intakes of SAFA were not associated with higher risks of CHD or stroke apparently, but studies did not take macronutrient replacement into account. Replacing SAFA by cis-polyunsaturated fatty acids was associated with significant CHD risk reduction, which was confirmed by randomized controlled trials. SAFA reduction had little direct effect on stroke risk. Cohort studies suggest that the food matrix and source of SAFA have important health effects.

Objective: The aim of this study is to examine the prevalence of coronary heart disease (CHD)–related disability (hereafter also “disability”) and the impact of CHD risk factors on disability in older adults in the Republic of Ireland (ROI) and Northern Ireland (NI). Method: Population attributable fractions were calculated using risk factor relative risks and disability prevalence derived from The Irish Longitudinal Study on Ageing and the Northern Ireland Health Survey. Results: Disability was significantly lower in ROI (4.1% vs. 8.8%). Smoking and diabetes prevalence rates, and the fraction of disability that could be attributed to smoking (ROI: 6.6%; NI: 6.1%), obesity (ROI: 13.8%; NI: 11.3%), and diabetes (ROI: 6.2%; NI: 7.2%), were comparable in both countries. Physical inactivity (31.3% vs. 54.8%) and depression (10.2% vs. 17.6%) were lower in ROI. Disability attributable to depression (ROI: 16.3%; NI: 25.2%) and physical inactivity (ROI: 27.5%; NI: 39.9%) was lower in ROI. Discussion: Country-specific similarities and differences in the prevalence of disability and associated risk factors will inform public health and social care policy in both countries.

Atherosclerosis Prevention

PEDIATRIC GENESIS OF ATHEROSCLEROSIS Atherosclerosis results from a variety of pathophysiologic disturbances, some currently recognized, and many undoubtedly not yet recognized, which in aggregate are identified as risk factors. Genetic and environmental influences conjointly affect the incidence and the severity of these risk factors and, thus, coronary heart disease (CHD) risk. Prophylaxis should be designed to prevent or retard the development of arterial plaques. This suggests that diagnostic and preventive efforts should begin in childhood. Eating habits are also probably established in childhood, allowing their early modification. The atherosclerotic plaque appears to have its genesis in childhood. The data from wartime autopsies confirm the presence of mature atherosclerotic lesions by the end of the second decade and emphasize the importance of primary atherosclerosis prevention beginning in the first and second decades. While there are clearly genetic factors in CHD, variation in rates in differing geographic areas appears less likely to be related to genetic than to environmental differences. Marked differences in plasma cholesterol levels are found in children in different geographic areas, generally paralleling pediatric cholesterol and saturated fat intake and the incidence of adult coronary heart disease. The relationships of elevated total plasma cholesterol levels to the incidence of coronary heart disease are clearly established in adults.

Objective: The independent prognostic value of prehypertension (preHTN) for incident coronary heart disease (CHD) remains unsettled. Using the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort study, we examined associations between preHTN and incident acute CHD and CVD death. Methods: REGARDS includes 30,239 black and white community-dwelling adults age 45 and older at baseline. Recruitment occurred from 2003-7, with baseline interviews and in-home data collection for physiologic measures. Follow-up is conducted by telephone every 6 months to detect events and deaths, which are adjudicated by experts. Systolic BP was categorized into <120 mmHg (n=4385), 120-129 mmHg (n=4000), 130-139 (n=2066), and hypertension was categorized into controlled (<140/90 mmHg on treatment) (n=8378), and uncontrolled (>140/90 mmHg) (n=5364). Incident acute CHD was defined as definite or probable myocardial infarction (MI) or acute CHD death. CVD death was defined as acute CHD, stroke, heart failure or other cardiovascular disease related. Cox proportional hazards models estimated the hazard ratios (HR) for incident CHD by BP categories, adjusting for sociodemographics and CHD risk factors. Results: The 23,393 participants free of CHD at baseline were followed for a median of 4.4 years. Mean age was 64.1, 58% were women and 42% were black. There was a significant interaction between sex and BP categories, therefore analyses were stratified by sex. There were 252 non-fatal and fatal acute CHD events among women and 407 among men. Among women, compared with SBP<120 mmHg, BP categories above SBP 120 mmHg were associated with incident CHD (adjusted HR for SBP120-129 mmHg=1.94 {95% CI 1.04-3.62]; SBP 130-139 mmHg=1.92 {0.95-3.87}; controlled HTN=2.16 {1.25-3.75}; uncontrolled HTN=3.25 {1.87-5.65}) in fully adjusted models. Among men, only uncontrolled HTN was associated with incident CHD (HR=1.55 {1.11-2.17}). Conclusion: In this sample, preHTN may be associated with incident CHD among women but not men.
