AbstractObjectiveThe objective of the present study was to examine the relationship between plasma alkyresorcinol (AR) concentrations, which are biomarkers of whole-grain intake, and atherosclerotic progression over 3 years in postmenopausal women with coronary artery disease.DesignPlasma AR concentrations were measured by a validated GC–MS method in fasting plasma samples. Atherosclerosis progression was assessed using change in mean minimal coronary artery diameter (MCAD) and percentage diameter stenosis (%ST), based on mean proximal vessel diameter across up to ten coronary segments. Dietary intake was estimated using a 126-item interviewer-administered FFQ.SettingA prospective study of postmenopausal women participating in the Estrogen Replacement and Atherosclerosis trial.SubjectsFor the analysis of plasma AR concentrations and atherosclerotic progression, plasma samples and follow-up data on angiography were available for 182 women.ResultsMean whole-grain intake was 9·6 (se 0·6) servings per week. After multivariate adjustment, no significant associations were observed between plasma AR concentrations and change in mean MCAD or progression of %ST. Plasma AR concentrations were significantly correlated with dietary whole grains (r=0·35, P<0·001), cereal fibre (r=0·33, P<0·001), bran (r=0·15, P=0·05), total fibre (r=0·22, P=0·003) and legume fibre (r=0·15, P=0·04), but not refined grains, fruit fibre or vegetable fibre.ConclusionsPlasma AR concentrations were not significantly associated with coronary artery progression over a 3-year period in postmenopausal women with coronary artery disease. A moderate association was observed between plasma AR concentrations and dietary whole grains and cereal fibre, suggesting it may be a useful biomarker in observational studies.

Background: Higher whole-grain intake has been associated with lower risk of cardiovascular disease in prospective observational studies. Few observational studies have incorporated biomarkers of whole-grain intake to confirm self-reported diet-disease associations. Plasma alkylresorcinols (AR) have been used as biomarkers for whole-grain wheat and rye intake. Objective: To assess the relationship between plasma AR concentrations and atherosclerotic progression over a 3-y period. Methods: Plasma AR concentrations were measured by gas chromatography mass spectrometry in baseline samples from 163 post-menopausal women (aged 49-78 y; median BMI: 29.0 kg/m2) with established coronary artery disease (CAD) who participated in the Estrogen Replacement and Atherosclerosis Study (enrolled 1995-1996) and had baseline food frequency questionnaire (FFQ), baseline and follow-up angiography measures, and complete covariate data. Dietary fiber intake was estimated by FFQ and energy-adjusted. Atherosclerosis progression, defined as change in mean minimum coronary artery diameter (MCAD, mm) and change in percent stenosis (%ST), was regressed on plasma AR in mixed models accounting for within-person correlations of coronary segments, and adjusted for the baseline measure, treatment allocation, clinic, age, race, BMI and follow-up time. Results: Median plasma AR was 16.1 nmol/L (interquartile range: 10.9-25.7). Over 3.1±0.7 years of follow-up, MCAD decreased by approximately 0.09±0.02 mm, while %ST increased by approximately 3.2±0.7%. No significant association was observed between AR and change in MCAD or %ST: a 10% increment in AR was associated with a -0.0002±0.0008 mm (P=0.76) change in MCAD and a 0.008±0.03 change in %ST (P=0.79). Further adjustment for lifestyle and risk factors did not materially change these results. As expected, AR correlated with FFQ- derived intake of cereal fiber (Spearman r=0.27, P<0.001) and whole grains (Spearman r=0.28, P<0.001). Of note, this cohort reported low whole-grain and cereal fiber intakes (9.5 servings/wk and 5.3 g/d, respectively). Conclusions: Plasma AR concentrations were not significantly associated with coronary narrowing over a 3-y period in postmenopausal women with CAD. We cannot rule out that large measurement errors in the biomarker, owing to low intake and short half-life may explain the findings.

The data with respect to stable coronary artery disease (SCAD) are mainly confined to main vessel disease. However, there is a lack of information and long-term outcomes regarding isolated side branch disease. This study aimed to evaluate long-term major adverse cardiac and cerebrovascular events (MACCEs) in patients with isolated side branch coronary artery disease (CAD). A total of 437 patients with isolated side branch SCAD were included. After a median follow-up of 38 months, the overall MACCE and all-cause mortality rates were 14.6% and 5.9%, respectively. Among angiographic features, 68.2% of patients had diagonal artery and 82.2% had ostial lesions. In 28.8% of patients, the vessel diameter was ≥2.75 mm. According to the American College of Cardiology lesion classification, 84.2% of patients had either class B or C lesions. Age, ostial lesions, glycated hemoglobin A1c, and neutrophil levels were independent predictors of MACCE. On the other hand, side branch location, vessel diameter, and lesion complexity did not affect outcomes. Clinical risk factors seem to have a greater impact on MACCE rather than lesion morphology. Therefore, the treatment of clinical risk factors is of paramount importance in these patients.

Abstract Introduction Smoking and obesity are recognized as important modifiable risk factors for coronary artery disease (CAD). However, the general perception that smoking protects against obesity is a common reason for starting, and/or not quitting smoking. Purpose To detect the quantity, quality and relative distribution of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) estimated by abdominal computed tomography in smokers versus non- smokers. Methods The abdominal muscular wall was traced manually to calculate SAT and VAT areas (cm2) (outside and inside abdominal muscular wall respectively) as well as SAT density [Hounsfield units (HU)] at L4-L5 in 409 consecutive patients referred for evaluation of chest pain by multi-slice computed tomography coronary angiography (MSCT-CA). Results 26% of the studied patients (n=107) were current smokers, while the remaining 74% (n=302) never smoked. Coronary artery atherosclerosis was more prevalent in smokers compared to non-smokers (64.5% vs 55.0%; p=0.09). Smokers had statistically significantly lower body mass index (BMI) (31.2±4.3 vs. 32.5±4.7 kg/m2; p=0.015), hip circumference (HC) (98.6±22.5 vs. 103.9±20.9 cm; p=0.031), total fat area (441.62±166.34 vs. 517.95±169.51cm2; p&lt;0.001), and SAT area (313.07±125.54 vs. 390.93±143.28 cm2; p&lt;0.001) as compared to non-smokers. However, smokers had statistically significantly greater waist-to-hip ratio (0.98±0.08 vs. 0.96±0.08; p=0.010), VAT/SAT area ratio (0.41±0.23 vs. 0.35±0.20; p=0.013), and denser SAT depot (−98.91±7.71 vs. −102.08±6.44 HU; p&lt;0.001). Conclusion Smoking contributes to CAD and to the pathogenic redistribution of body fat towards VAT, through limiting SAT potential to expand. Funding Acknowledgement Type of funding source: None

The Impact

Background: Postmenopausal women experience rapid progression of coronary artery disease. Vitamin D deficiency appears to be a modifiable risk factor for cardiovascular diseases. This study aimed to analyze the impact of 25-hydroxyvitamin D3 (25(OH)D) level on the severity of coronary atherosclerosis and its potential cardioprotective effect in postmenopausal women. Material and Methods: The study prospectively recruited 351 women in postmenopausal age undergoing coronary angiography. The severity of coronary atherosclerosis was assessed using the Coronary Artery Surgery Study Score (CASSS). A level of 25(OH)D was measured with electrochemiluminescence. Results: Women with more severe coronary atherosclerosis have significantly lower 25(OH)D serum level (p = 0.0001). Vitamin D (β = −0.02; p = 0.016), hypertension (β = 0.44; p = 0.025), age (β = 0.02; p = 0.003), and history of MI (β = 0.63; p < 0.0001), were shown as CASSS determinants. Age, hyperlipidemia, and history of MI were found to determine the level of vitamin D (all p < 0.05). Women with a three-vessel disease hospitalized due to ACS, with a history of MI, hyperlipidemia and hypertension presented the lowest vitamin D level. Conclusions: Our study showed that lower serum 25(OH)D in postmenopausal women is associated with more significant stenosis in the coronary arteries. Therefore, we suggest considering low vitamin D level as a potential risk factor for coronary artery disease.
