Inflammatory biomarkers as predictors of heart failure in women without obstructive coronary artery disease: A report from the NHLBI-sponsored Women's Ischemia Syndrome Evaluation (WISE).

ABSTRACT: Women with signs and symptoms of ischemia, no obstructive coronary artery disease (CAD) and preserved left ventricular ejection fraction (EF) often have diastolic dysfunction and experience elevated rates of major adverse cardiac events (MACE), including heart failure (HF) hospitalization with preserved ejection fraction (HFpEF). We evaluated the predictive value of inflammatory biomarkers for long-term HF hospitalization and all-cause mortality in these women.We performed a cross-sectional analysis to investigate the relationships between inflammatory biomarkers [serum interleukin-6 (IL-6), C-reactive protein (hs-CRP) and serum amyloid A (SAA)] and median of 6 years follow-up for all-cause mortality and HF hospitalization among women with signs and symptoms of ischemia, non-obstructive CAD and preserved EF. Multivariable Cox regression analysis tested associations between biomarker levels and adverse outcomes.Among 390 women, mean age 56 ± 11 years, median follow up of 6 years, we observed that there is continuous association between IL-6 level and HF hospitalization (adjusted hazard ratio [AHR] 2.5 [1.2-5.0], p = 0.02). In addition, we found significant association between IL-6, SAA levels and all-cause mortality AHR (1.8 [1.1-3.0], p = 0.01) (1.5 [1.0-2.1], p = 0.04), respectively.In women with signs and symptoms of ischemia, non-obstructive CAD and preserved EF, elevated IL-6 predicted HF hospitalization and all-cause mortality, while SAA level was only associated with all-cause mortality. These results suggest that inflammation plays a role in the pathogenesis of development of HFpEF, as well all-cause mortality.

Project description:BackgroundWomen presenting with signs and symptoms of myocardial ischemia frequently have no or nonobstructive coronary artery disease (CAD).ObjectiveThis study aimed to investigate the associations between angiographic measures and longer-term clinical outcomes among women with signs and symptoms of ischemia referred for coronary angiography.MethodsA prospective cohort analysis of women referred for coronary angiography and enrolled in the National Heart, Lung, and Blood Institute-sponsored WISE was performed. An angiographic severity score was prospectively developed, assigning points for any stenosis weighted by stenosis severity, location, and collaterals and was then tested for prediction for adverse outcome in 917 women, over a median of 9.3 years.SettingThe study was conducted in referral centers.PatientsWomen with signs and/or symptoms of myocardial ischemia referred for coronary angiography were consecutively consented and enrolled in a prospective study.Main outcome measuresMain outcomes included first occurrence of cardiovascular death or nonfatal myocardial infarction. Hospitalization for angina was a secondary outcome.ResultsCardiovascular death or myocardial infarction at 10 years occurred in 6.7%, 12.8%, and 25.9% of women with no, nonobstructive, and obstructive CAD (P < .0001), respectively. Cumulative 10-year cardiovascular death or myocardial infarction rates showed progressive, near-linear increases for each WISE CAD severity score range of 5, 5.1 to 10, 10.1 to 20, 20.1 to 50, and >50. The optimal threshold in the WISE severity score classifications for predicting cardiovascular mortality was >10 (eg, 5.0-10 vs 10.1-89), with both a sensitivity and specificity of 0.64 and an area under the curve of 0.64 (P = .02, 95% CI 0.59-0.68).ConclusionsAmong women with signs and symptoms of ischemia, nonobstructive CAD is common and associated with adverse outcomes over the longer term. The new WISE angiographic score appears to be useful for risk prediction in this population.

Project description:Paraoxonase (PON), a high-density lipoprotein-associated enzyme, is believed to protect against low-density lipoprotein oxidation and thus affects the risk of coronary artery disease (CAD). Three polymorphisms in the PON1 (Leu55Met and Gln192Arg) and PON2 (Ser311Cys) genes have been shown to be associated with the risk of CAD in several European or European-derived populations. In the present study, we examined the associations between these three markers and the severity of CAD as determined by the number of diseased coronary artery vessels in 711 subjects (589 whites and 122 blacks) from the Women's Ischemia Syndrome Evaluation (WISE) study. WISE is a National Heart, Lung, and Blood Institute-sponsored multicenter study designed to address issues related to ischemic-heart-disease recognition and diagnosis in women. Subjects were classified as having normal/minimal CAD (<20% stenosis), mild CAD (20%-49% stenosis), and significant CAD (>/=50% stenosis). The women who had >/=50% stenosis were further classified into groups with one-, two-, or three-vessel disease if any of the three coronary arteries had diameter stenosis >/=50%. No significant association was found between the PON polymorphisms and stenosis severity in either white or black women. However, among white women, when data were stratified by the number of diseased vessels, the frequency of the PON1 codon 192 Arg/Arg genotype was significantly higher in the group with three-vessel disease than in the other groups (those with one-vessel and two-vessel disease) combined (17.02% vs. 4.58%; P=.0066). Similarly, the frequency of the PON2 codon 311 Cys/Cys genotype was significantly higher in the group with three-vessel disease than in the other groups combined (15.22% vs. 4.61%; P=.018). The adjusted odds ratios for the development of three-vessel disease were 2.80 (95% confidence interval 1.06-7.37; P=.038) for PON1 codon 192 Arg/Arg and 3.68 (95% confidence interval 1.26-10.68; P=.017) for PON2 codon 311 Cys/Cys. Our data indicate that the severity of CAD, in terms of the number of diseased vessels, may be affected by common genetic variation in the PON gene cluster, on chromosome 7.
