Abstract Objectives Micro ribonucleic acids (miRNAs) are small non-coding RNA molecules that control gene expression by translational inhibition. Exercise has been shown to affect several miRNAs’ expression in healthy subjects, but this has not yet been studied in patients with coronary artery disease (CAD). Since exercise training confers beneficial long-term effects and may also trigger acute coronary events, it is of utmost interest to be able to identify those who are risk for untoward effects. Therefore, we set out to assess miRNA expression in response to maximal ergospirometry in patients with CAD. Methods Total RNA was extracted from blood drawn immediately before and 5 min after maximal cycle-ergospirometry (10 male and 10 female CAD patients). A qRT-PCR was performed for 187 target miRNAs associated with endothelial function/dysfunction, cardiovascular disease, myocardial infarction, and sudden cardiac death. Results In response to a maximal ergospirometry, 33 miRNAs significantly changed their expression levels. Of these miRNAs 16 were significantly differently expressed between gender. Using multi-variance analysis, nine miRNAs (let-7e-5p; miR-1; miR-19b-1-5p; miR-103a-3p; miR-148b-3p; miR-181b-5p; miR-188-5p; miR-423-5p; miR-874-3p) showed significantly different responses to maximal ergospirometry between genders. Conclusions We report for the first time that in patients with CAD, miRNA expression is amenable to maximal ergospirometry and that the extent of changes differs between genders. Affected by exercise and gender were miRNAs that are associated, among others, with pathways for glucose metabolism, oxidative stress, and angiogenesis. Future studies should assess whether disease-specific miRNA expression in response to maximal exercise might serve as a marker for patient outcome.

Plasma concentrations of HDL-C have long been shown to correlate inversely with risk of coronary artery disease (CAD), however the causal nature of this association has not been established. Here we examine the chemical composition and phosphoshingolipidome of HDL in a cohort of subjects with premature CAD, despite having HDL levels ≥90th percentile. We hypothesized that HDL from hyperalphalipoproteinemic subjects with CAD would have distinct compositional changes compared to healthy hyperalphalipoproteinemic subjects, which may relate a reduction in HDL functionality and a pro-atherogenic state. Subjects with HDL ≥90th percentile and CAD (HHDL+CAD, n=25) were compared to healthy subjects with HDL ≥90th percentile (HHDL, n=23). A group of healthy controls with HDL between the 25th and 75th percentile (n=11) was used as reference. HDL subfractions were isolated from EDTA plasma using isopycnic density gradient ultracentrifugation and their chemical composition was assayed using commercial enzymatic assay kits. Quantification of >160 molecular species of total HDL phospho- and sphingolipids was accomplished via a novel method using LC-ESI/MS/MS analysis. The most striking differences were observed in total HDL phospho- and sphingolipid subclasses between groups. When expressed as a percentage of total phosphosphingolipid, phosphatidylcholine (PC) and phosphatidylinositol (PI) were depleted in HHDL+CAD group compared to HHDL, while sphingomyelin (SM) was increased, resulting in a lower PC/SM ratio. The HDL PC/SM ratio has previously been shown to correlate with HDL surface fluidity and antioxidative activity. Additionally, enrichment of PI, a minor, negatively charged phospholipid, has been shown to stimulate cholesterol efflux to reconstituted HDL. Reduction in these two metrics, observed in the HHDL+CAD group, may indicate functionally deficient HDL and may represent pro-atherogenic, HDL-associated biomarkers of CAD in hyperalphalipoproteinemia.

Single ultrasound assessment of either intima-media thickness (IMT) or plaque echolucency of carotid artery is considered a surrogate for systemic atherosclerotic burden and provides prognostic information for coronary events. The assessment of IMT and plaque echolucency of carotid artery has the advantage of obtaining structural and compositional information on atherosclerotic plaques in a single session. This study examined the hypothesis that the combined ultrasound assessment of IMT and echolucency in a carotid artery may have an additive effect on the prediction of coronary events in patients with coronary artery disease (CAD). Ultrasound assessment of carotid IMT and plaque echolucency with integrated backscatter (IBS) analysis (intima-media IBS value minus adventitia IBS) was performed in 411 patients with CAD and carotid plaques (IMT ≥ 1.1 mm). The plaque with the greatest axial thickness in carotid arteries was the target for measurement of maximum IMT (plaque-IMTmax) and echolucency (lower IBS reflects echolucent plaque). All patients were prospectively followed up for 70 months or until the occurrence of one of the following coronary events: cardiac death, nonfatal myocardial infarction, or unstable angina pectoris requiring revascularization. During follow-up, 49 coronary events occurred (cardiac death in 2, myocardial infarction in 10, unstable angina in 37). In a multivariate Cox hazards analysis, plaque-IMTmax and plaque echolucency (lower IBS value) were significant predictors of coronary events (HR; 1.82 and 0.85, 95% CI 1.2 – 2.9 and 0.80 – 0.91, respectively, both p < 0.01) independently of age, LDL-C levels, and diabetes. When outcomes were stratified according to plaque-IMTmax and plaque echolucency in combination or alone, the combination of plaque-IMTmax and plaque echolucency was the strongest predictor of events, followed by plaque echolucency and plaque-IMTmax, on the basis of the c -statistic (area under the ROC curve; 0.80, 0.73, and 0.71, respectively). Combined ultrasound assessment of IMT and echolucency of carotid plaque had an additive value on the prediction of coronary events, and these simultaneous ultrasound measurements may be useful for risk stratification in CAD.

SummaryThrombus formation after rupture of an atherosclerotic plaque plays a crucial role in coronary artery disease (CAD). A decreased endogenous fibrinolytic system and prothrombotic factors are supposed to influence coronary thrombosis. It was our aim to investigate the predictive value of tissue plasmino-gen activator (t-PA) antigen, von Willebrand Factor, Lipoprotein (a) and anti-cardiolipin antibodies for major adverse coronary events in patients with stable CAD in a prospective cohort study of more than 10 years.We observed 141 patients with angiographically proven CAD for a median follow-up period of 13 years. t-PA antigen was the only marker predicting coronary events (logistic regression, p = 0.044) with a poor prognosis for patients in the 5th quintile with an odds ratio of 7.3 (compared to the 1st quintile). The odds ratio even increased to 10.0 for coronary events associated with the “natural course” of CAD excluding events due to restenosis. t-PA antigen had a slightly higher prognostic power (ROC curve; AUC = 0.69) than fasting glucose (AUC = 0.68) and cholesterol (AUC = 0.67). Triglycerides influenced plasma levels of t-PA antigen (regression, p < 0.001). The predictive value of t-PA antigen remained significant after adjustment for inflammation (logistic regression, p = 0.013) and extent of CAD (p = 0.045) but disappeared adjusting for insulin resistance (p = 0.12).In conclusion t-PA antigen predicted coronary events during a very long-term follow-up with a comparable prognostic power to established cardiovascular risk factors. Markers of insulin resistance influenced t-PA antigen and its predictive value.Part of this paper was originally presented at the joint meetings of the 16th International Congress of the International Society of Fibrinolysis and Proteolysis (ISFP) and the 17th International Fibrinogen Workshop of the International Fibrinogen Research Society (IFRS) held in Munich, Germany, September 2002.
