Abstract Background Traditional cardiovascular risk factors and a large number of biomarkers are well known in their association with the diagnosis and prognosis of coronary artery disease (CAD). Cyclophilin C (CypC) is a subfamily of immunophilins that modulates macrophage activation and redox homeostasis. Purpose This study is aimed at investigating the changes in serum CypC levels and their relationship with cardiovascular events at 12 months of follow-up in CAD patients. Methods The study included a total of 125 subjects (40 patients with acute CAD, 40 patients with chronic CAD and 45 control volunteers). We analyzed plasma CypC levels from baseline to 6 and 12 months for a better understanding of its behaviour in atherosclerosis. Results Serum CypC levels were shown to be gradually increased in CAD patients [(30.63 pg/mL ± 3.77 at baseline, 38.70 pg/mL ± 6.41 at 6 months (p=0.25) and 47.27 pg/mL ± 5.65 at 12 months (p=0.007)]. In addition, serum CypC levels during the follow-up were a significant predictor of CAD (c- statistic 0.76 at 6 months and 0.89 at 12 months; p<0.001). Despite it, there was no significant association between CypC and cardiovascular events, but serum CypC levels tended to be higher in patients suffering cardiovascular events during the follow-up (29.02 pg/mL ± 6.39 vs 79.96 pg/mL ± 22.18; p=0.029). In this regard, plasma levels of hsCRP >2.3 mg/L plus NT-proBNP >300pg/mL together were significant predictors of cardiovascular events during the follow-up in CAD patients with CypC levels >17.5 pg/mL (p=0.048). Conclusions Taken together, our results suggest that serum CypC levels increase during the follow-up in CAD patients and could be a novel biomarker with a possible prognostic value in combination with hsCRP and NT-proBNP.

Abstract Background In the COMPASS trial, low dose rivaroxaban (2.5 mg/12h) on top of aspirin showed a 26% reduction in major cardiovascular events in patients with stable coronary artery disease (sCAD). However, information about external applicability of these results is limited. Our objective was to assess potential eligibility for this treatment in a “real world” cohort of Spanish patients with sCAD and to evaluate the incidence of major events in the long-term follow up in this population. Methods The CICCOR registry (“Chronic ischemic heart disease in Cordoba”, in Spanish “Cardiopatía isquémica crόnica en Cordoba”) is a prospective, monocentric study. From February 1, 2000 to January 31, 2004, all consecutive patients with sCAD attended at two outpatient cardiology clinics in a city of the south of Spain were included in the study and prospectively followed. The COMPASS inclusion and exclusion criteria were applied to this cohort, and the proportion of patients potentially eligible for this trial was described. The rate of the main COMPASS end-point (the composite of acute myocardial infarction, stroke, or cardiovascular death), as well as mortality rates, were investigated in this subset of patients, and compared with those of sCAD patients included in the aspirin alone group of the COMPASS trial. Results From a total population of 1268 patients, 1246 subjects presented enough data to assess eligibility. Among these, 575 patients (46%) had exclusion criteria, and another 229 (18%) did not fulfill the inclusion criteria and were not eligible. The main reasons for exclusion were requirement for dual antiplatelet therapy within 1 year of an acute coronary syndrome or coronary stent implantation (70%), high-bleeding risk (33%), other non-aspirin antiplatelet therapy (13%), atrial fibrillation (12%), anticoagulant use (11%), history of ischemic stroke (5%) and heart failure with severe left ventricular dysfunction (4%). The reason for not fulfilling inclusion criteria was the absence of additional high risk factors in patients younger than 65 years. The potentially eligible population included 442 patients (35% of evaluable patients), with up to 17 years of follow-up (median 9 years, IQR 4–15 years, only 1 patient lost in follow-up, 4174 patients-years of observation). These patients experienced higher primary outcome event rates than coronary patients actually enrolled in the aspirin alone arm of COMPASS (5.1% versus 2.9% per year), and higher rates of cardiovascular (4.0% versus 1.1%) and all-cause mortality (6.3 versus 2.1%, p<0.00005 for all comparisons). Conclusion More than one third of “real world” patients with sCAD of this prospective Spanish registry could be potentially eligible for low dose rivaroxaban therapy, according to COMPASS inclusion and exclusion criteria. This population had a higher risk of cardiovascular events and mortality than COMPASS participants with sCAD in the reference aspirin group. Funding Acknowledgement Type of funding source: None

Abstract Background High lipoprotein(a) [Lp(a)] levels have been shown to increase Myocardial Infarction (MI) and all-cause mortality. However, studies evaluating the optimal preventive measures for that subset of cardiac patients are scarce. This study aims to study the outcomes of aspirin use versus no aspirin for the prevention of all-cause mortality and myocardial infarction in patients with high Lp(a) levels. Purpose We sought to determine the effect of Aspirin in reducing the rate of MI and all-cause mortality among patients with high lipoprotein(a) [Lp(a) ≥50mg/dL] Methods Patients who attended the preventive cardiology clinic from 2005 to 2016 and included in the Preventive Cardiology Database were included in the current single-center, retrospective, observational cohort study that was conducted according to the guidelines of the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology Statement) checklist. The primary outcome was the incidence of myocardial infarction and the secondary outcome was all-cause mortality. Patients were excluded in cases of I) Lp(a)a <50mg/dL, II) history of malignancy, or III) being on anticoagulation/ dual antiplatelet therapy. The median duration of follow-up was 92 months from time of Lp(a) measurement to the last follow-up. Continuous variables were expressed as means ± standard deviation or median (IQR), and categorical variables were expressed as percentages (%). All statistical tests were two-sided. A propensity score-matched analysis was performed with 1:1 nearest match for Age, Gender, Race, Smoking status, BMI, Diabetes, Peripheral artery disease, Carotid artery disease, coronary artery disease, chronic kidney disease, Heart failure, Hypertension, Dyslipidemia, Stroke, family history of coronary artery disease, Lp (a), LDL, HDL, Triglycerides, glucose and total cholesterol. Results 1,805 patients fulfilled the inclusion and exclusion criteria out of 7,410 patients initially identified with recorded Lp(a) levels in the Preventive Cardiology Database. Of these, 376 patients were taking aspirin, and 1429 patients were not receiving aspirin. After propensity score matching for different baseline characteristics and comorbidities as mentioned above, 316 patients were matched in each group. Patients who were on Aspirin had a significantly lower rate of MI events compared to patients who were not on aspirin (6.96% vs 12.02%, P=0.03) and a lower rate, however statistically non-significant, of all-cause mortality (2.84% vs 4.11%, P=0.385). Conclusion The use of aspirin in patients with elevated Lp(a) levels significantly lowers the rate of myocardial infarction events. Larger randomized clinical trials are warranted to evaluate the use of aspirin for primary and secondary prevention of major adverse cardiovascular events in patients with high Lp(a) levels.

TG-rich lipoprotein (TRL)-related biomarkers, including TRL-cholesterol (TRL-C), remnant-like lipoprotein particle-cholesterol (RLP-C), and apoC-III have been associated with atherosclerosis. However, their prognostic values have not been fully determined, especially in patients with previous CAD. This study aimed to examine the associations of TRL-C, RLP-C, and apoC-III with incident cardiovascular events (CVEs) in the setting of secondary prevention of CAD. Plasma TRL-C, RLP-C, and total apoC-III were directly measured. A total of 4,355 participants with angiographically confirmed CAD were followed up for the occurrence of CVEs. During a median follow-up period of 5.1 years (interquartile range: 3.9–6.4 years), 543 (12.5%) events occurred. Patients with incident CVEs had significantly higher levels of TRL-C, RLP-C, and apoC-III than those without events. Multivariable Cox analysis indicated that a log unit increase in TRL-C, RLP-C, and apoC-III increased the risk of CVEs by 49% (95% CI: 1.16–1.93), 21% (95% CI: 1.09–1.35), and 40% (95% CI: 1.11–1.77), respectively. High TRL-C, RLP-C, and apoC-III were also independent predictors of CVEs in individuals with LDL-C levels ≤1.8 mmol/l (n = 1,068). The addition of RLP-C level to a prediction model resulted in a significant increase in discrimination, and all three TRL biomarkers improved risk reclassification. Thus, TRL-C, RLP-C, and apoC-III levels were independently associated with incident CVEs in Chinese CAD patients undergoing statin therapy.

Abstract Background Current hypertension guidelines necessitate an individualized cardiovascular risk assessment through a process that includes several parameters and remains challenging. Exercise capacity has been strongly associated with prognosis in cardiovascular disease and can be easily assessed by the exercise treadmill test (ETT). Purpose The aim of the present study was to investigate theprognostic role of exercise capacity for future cardiovascular events in a cohort of essential hypertensive subjects. Methods We followed up 1037 hypertensive adults (mean age 56 years, 53% males) with no previous history of cardiovascular disease, for a mean period of 6±3 years. During the baseline visit all subjects underwent a complete echocardiographic study, office blood pressure measurements, ECG, routine blood testing and an ETT with a Bruce protocol.During follow-up, all subjects were reviewed at least annually. Exercise capacity was expressedwithexercise duration the distribution of which was split by the median (9min). Accordingly, the subjects were classified into those with high (51%) and low exercise capacity (49%). The cardiovascular endpoint of interest was the composite of coronary artery disease and stroke. Results The incidence of cardiovascular eventsduring the follow-up period was 4.1% (35 cases of coronary artery disease and 10 cases of stroke).Cox regression analysis revealed that high exercise capacity was associated with a lower risk for future cardiovascular events (HR = 0.35 (95% CI 0.172–0.741, p=0.006). In multivariate models adjusting for standard clinical and laboratory cardiovascular risk factors this association was sustained. Conclusion Exercise duration shows a significant prognostic value for future CV events among hypertensivepatients. Exercise capacity assessment by means of TTE could enhance the identification of asymptomatic hypertensives at higher risk. Funding Acknowledgement Type of funding source: None
