Background and Purpose: General population studies have shown that elevated Lp(a) (lipoprotein[a]) levels are an emerging risk factor for cardiovascular disease and subsequent cardiovascular events. The role of Lp(a) for the risk of secondary MACE in patients undergoing carotid endarterectomy (CEA) is unknown. Our objective is to assess the association of elevated Lp(a) levels with the risk of secondary MACE in patients undergoing CEA. Methods: Lp(a) concentrations were determined in preoperative blood samples of 944 consecutive patients with CEA included in the Athero-Express Biobank Study. During 3-year follow-up, major adverse cardiovascular events (MACE), consisting of myocardial infarction, stroke, and cardiovascular death, were documented. Results: After 3 years follow-up, Kaplan-Meier cumulative event rates for MACE were 15.4% in patients with high Lp(a) levels (>137 nmol/L; >80th cohort percentile) and 10.2% in patients with low Lp(a) levels (≤137 nmol/L; ≤80th cohort percentile; log-rank test: P =0.047). Cox regression analyses adjusted for conventional cardiovascular risk factors revealed a significant association between high Lp(a) levels and 3-year MACE with an adjusted hazard ratio of 1.69 (95% CI, 1.07–2.66). One-third of MACE occurred within 30 days after CEA, with an adjusted hazard ratio for the 30-day risk of MACE of 2.05 (95% CI, 1.01–4.17). Kaplan-Meier curves from time point 30 days to 3 years onward revealed no significant association between high Lp(a) levels and MACE. Lp(a) levels were not associated with histological carotid plaque characteristics. Conclusions: High Lp(a) levels (>137 nmol/L; >80th cohort percentile) are associated with an increased risk of 30-day MACE after CEA. This identifies elevated Lp(a) levels as a new potential risk factor for secondary cardiovascular events in patients after carotid surgery. Future studies are required to investigate whether Lp(a) levels might be useful in guiding treatment algorithms for carotid intervention.

SummaryWe aimed at challenging the prognostic accuracies of myeloperoxidase (MPO) and antibodies anti-apolipoprotein A-1 (anti-apoA-1 IgG), alone or in combination, for major adverse cardiovascular events (MACE) prediction, one year after carotid endarterectomy (CEA). In this prospective single centre study, 178 patients undergoing elective CEA were included. Serum anti-apoA-1 IgG and MPO were assessed by enzyme-linked immunosorbent assay prior to the surgery. Post-hoc determination of the MPO cut-off was performed by receiver operating characteristics (ROC) analyses. MACE was defined by the occurrence of fatal or non-fatal acute coronary syndromes or stroke during one year follow-up. Prognostic accuracy of anti-apoA-1 IgG was assessed by ROC curve analyses, survival analyses and reclassification statistics. During follow-up, 5% (9/178) of patients presented a MACE, and 29% (52/178) were positive for anti-apoA-1 IgG. Patients with MACE had higher median MPO and anti-apoA-1 IgG levels at admission (p=0.01), but no difference for the 10-year global Framingham risk score (FRS) was observed (p=0.22). ROC analyses indicated that both MPO and anti-apoA-1 IgG were significant predictors of subsequent MACE (area under the curve [AUC]: 0.75, 95% confidence interval [95%CI]: 0.61–0.89, p=0.01; and 0.74, 95%CI: 0.59–90; p=0.01), but combining anti-apoA-1 IgG positivity and MPO>857 ng/ml displayed the best predictive accuracy (AUC: 0.78, 95%CI: 0.65–0.91; p=0.007). It was associated with a poorer MACE-free survival (98.2% vs. 57.1%; p<0.001, LogRank), with a positive likelihood ratio of 13.67, and provided incremental predictive ability over FRS. In conclusion, combining the assessment of anti-apoA-1 IgG and MPO appears as a promising risk stratification tool in patients with severe carotid stenosis.

Background Systemic lupus erythematosus is associated with an increased risk of cardiovascular disease. Low-dose aspirin, hydroxychloroquine and statins have been suggested to play a prophylactic role of cardiovascular events. This study is devoted to reviewing the literature on the topic and assessing the effects of these drugs in preventing a first cardiovascular event in a two-centre Italian series. Methods A PubMed search on cardiovascular prevention in systemic lupus erythematosus was performed. Moreover, systemic lupus erythematosus patients admitted to two centres from 2000–2015, who at admission had not experienced any cardiovascular event, were investigated. Aspirin, hydroxychloroquine and statin use, and the occurrence of any cardiovascular event, were recorded at each visit. Kaplan-Meier and Cox regression analyses were performed to evaluate the role of traditional, disease-related cardiovascular risk factors and of each of the three drugs in the occurrence of new cardiovascular events. Results The literature search produced conflicting results. Two hundred and ninety-one systemic lupus erythematosus patients were included in the study and followed for a median of eight years. During follow-up, 16 cardiovascular events occurred. At multivariate analysis, taking aspirin (hazard ratio: 0.24) and hydroxychloroquine for more than five years (hazard ratio: 0.27) reduced, while antiphospholipid antibody positivity (hazard ratio: 4.32) increased, the risk of a first cardiovascular event. No effect of statins emerged. Conclusion Our study confirms an additive role of aspirin and hydroxychloroquine in the primary prophylaxis of cardiovascular events in Italian patients with systemic lupus erythematosus. The lack of any detected effect in previous reports may depend on the design of studies and their short follow-up period.

AbstractCyproterone acetate (CPA) is a synthetic steroid hormone. We assessed the association between the use of CPA and the risk of developing meningioma.In a historical prospective cohort study, using Danish national healthcare registers we included a cohort of 5,730,654 individuals, among whom 1,982 were exposed to CPA. During follow-up, we identified 8,957 cases of meningioma, of which 16 were exposed to CPA. From 2013 to 2019 the number of new users increased from 18.1 to 62.3 new users per million, while the proportion of new users who were transgender increased from 18.4 to 68.3%. Analyses showed a significantly increased risk of meningioma according to cumulative dose of CPA; 0.1-10 grams of CPA, incidence rate 78.8 (95% CI 15.7-141.9) per 100.000 person years and adjusted hazard ratio 7.0 (3.1-15.6); >10 grams of CPA, incidence 187.5 (71.3-303.7) and adjusted hazard ratio 19.2 (10.3-35.8), as compared to the background population.In conclusion, the cumulative dose of CPA was associated with an increased incidence and hazard ratio of meningioma, showing a dose-response relationship. The number of new CPA users increased more than 3-fold from 2013 to 2019, primarily driven by new transgender users.

Abstract INTRODUCTION: Type 1 Diabetes (T1D) patients have an increased risk for major adverse cardiovascular events (MACE). Pancreas Transplantation Alone (PTA) in patients with T1D achieves near normal glucose control for a prolonged period but limited data are available to date regarding MACE during a 10 year follow up period after the procedure. OBJECTIVE: We studied incidence of MACE after PTA in T1D patients over a 10 year follow-up period. METHODS: Retrospectively, we studied 113 T1D recipients of PTA at Mayo Clinic, Rochester with the procedure performed between January 1998 and August 2018 and follow up of at least 1 year. Data were collected before transplantation and up to 10 year follow up after the first PTA. MACE data were gathered until primary non function, re-transplantation, or complete loss of c-peptide (&lt;0.01ng/ml). We report vascular risk factors including hypertension, hyperlipidemia, smoking and BMI along with MACE (defined as cardiac events as unstable angina, Myocardial Infarction (MI), need for re-vascularization, cardiac death, cerebral events as Transient ischemic attack (TIA), stroke, need for re-vascularization and peripheral arterial disease as need for re-vascularization, gangrene and amputation). RESULTS: Eighteen subjects had pre-transplant MACE. A total of 14 subjects had graft failure within 24 to 36 hours due to thrombosis, with 3 in pre-transplant MACE cohort and 11 in no MACE cohort. Thus, we followed 99 subjects for the development of post-transplant MACE for a period of 6.3 ± 3.6 years. T1D subjects with MACE (n=15) had baseline characteristics: Age 48± 7.8 years, gender F/M 9/6,, duration of diabetes 33 ± 12 years, BMI 26± 3.1(Kg/m2), HbA1c 9.3 ± 1.5% and C-peptide 0.09 ng/ml. 84 T1D patients without MACE were age 42 ± 10.6 years, gender F/M 55/29, duration of diabetes 26.5 ± 10.7 years, BMI 26 ± 5.2(Kg/m2), HbA1c 6.7 ± 2.5 and C-peptide 0.09 ng/ml. There are a total of 584 person-years of follow up to first MACE event and 632 person-years of graft failure, death or last follow-up. Nine patients developed 11 MACE events post-PTA. Therefore, the event rate is 1.5 MACE events per 100 person-years for first MACE event and the total event rate is 1.7 MACE events per 100 person-years of follow-up. Age, smoking (yes), gender, duration of diabetes, HTN and Hyperlipidemia presence did not show any significant impact on post-transplant MACE outcome based on univariate Cox regression but the pre-transplant BMI (HR = 1.14; CI = (1.04, 1.26); p = 0.008) and pre-transplant HbA1c (HR = 1.26; CI = (1.06, 1.51); p = 0.01) showed statistically significant impact. CONCLUSIONS: At our center, MACE is low in PTA recipients. There is no impact of presence of pre-transplant MACE on development of post-transplant MACE but pre-transplant BMI and HbA1c account for risk of MACE.

Abstract Purpose Tobacco cigarette smoking and decreased concentrations of testosterone are major risk factors of erectile dysfunction (ED) and independent predictors of cardiovascular disease (CVD). We investigated, whether testosterone deficiency has a complementary predictive value for CVD events in smokers with ED. Methods A cohort of 398 men with ED and without known atherosclerotic CVD (mean age: 55±10 years) were followed for the occurrence of major adverse cardiovascular events (MACE), (CVD death, coronary artery disease, stroke). Total testosterone (TT) levels were measured in all patients. Results Among the study population, 205 (52%) were smokers. During a mean follow-up of 6 years (range: 1–11 years), 30 (7.5%) patients demonstrated a MACE. Baseline TT levels were significantly lower and prevalence of smoking was higher in the CV-event group than the event-free survival group (P&lt;0.01 and P&lt;0.05, respectively). Kaplan–Meier analysis showed that patients with low TT (≤4.0 ng/mL) had a worse prognosis than patients with TT &gt;4.0 ng/mL (log rank: 6.52, P=0.011), and that smokers had a greater risk of adverse events than never smokers (log rank: 4.42, P=0.04). We then stratified all patients into four groups, on the basis of smoking status (current/never smokers) and low or high TT (≤ or &gt;4.0 ng/mL) and cardiac event-free survival curves were constructed by Kaplan–Meier analysis (figure). The event-free rate in smokers with low TT is significantly lower than that of smokers with low TT or never smokers with normal TT (log rank: 11.3, P=0.02). Smokers with low TT had an almost 4-fold higher risk of MACEs compared to never smokers with normal TT (adjusted hazard ratio: 3.91; P=0.030). Conclusion Cigarette smoking combined with low TT concentration is associated with a shorter event-free period compared with either smoking or testosterone deficiency alone. The measurement of testosterone concentration may be useful to further stratify the risk of ED smokers without known CVD. FUNDunding Acknowledgement Type of funding sources: None.

Abstract Background: Suppression of tumorigenesis-2 is implicated in the myocardial overload and it was long been recognized as an inflammation marker related to heart failure and acute coronary syndromes, but the data on prognostic value of suppression of tumorigenesis-2 on patients with coronary artery disease remains limited. The study ought to investigate the prognostic value of suppression of tumorigenesis-2 in patients with established coronary artery disease.Methods: In this prospective cohort study, a total of 3641 consecutive patients were included. The primary end point was major adverse cardiovascular events. Kaplan-Meier survival estimates indicated that the patients with higher levels of ST2 (ST2> 19 ng/ml) had a significantly increased risk of MACEs (log-rank p＜0.001) and all-cause death (log-rank p＜0.001). The secondary end point was all-cause death. The association between suppression of tumorigenesis-2 and outcomes was investigated using multivariable COX regression.Results: During a median follow up of 6.4 years, there were 775 patients had the occurrence of major adverse cardiovascular events and 275 patients died. Kaplan-Meier survival estimates indicated that the patients with higher levels of ST2 (ST2> 19 ng/ml) had a significantly increased risk of MACEs (log-rank p＜0.001) and all-cause death (log-rank p＜0.001). Multiple COX regression models showed that higher level of suppression of tumorigenesis-2 was an independent predictor in developing major adverse cardiovascular events (HR=1.36, 95% CI 1.17-1.56, p＜0.001) and all-cause death (HR=2.01, 95%CI 1.56-2.59, p＜0.001). The addition of suppression of tumorigenesis-2 to established risk factors significantly improved risk prediction of the composite outcome of major adverse cardiovascular events and all-cause death (c-statistic, net reclassification index, and integrated discrimination improvement, all p＜0.05).Conclusions: Higher level of suppression of tumorigenesis-2 is significantly associated with long-term all-cause death and major adverse cardiovascular events. Suppression of tumorigenesis-2 may provide incremental prognostic value beyond traditional risk factors.

Abstract BackgroundThe relationship between small dense low-density lipoprotein cholesterol (sdLDL-C) and different cardiovascular events has been observed in several large community studies, and the results have been controversial. However, there is currently no cross-sectional or longitudinal follow-up study on sdLDL-C in the Chinese hypertension population.MethodsWe analyzed the association of plasma sdLDL-C levels with major adverse cardiovascular events in 1325 subjects from a longitudinal follow-up community-based population in Beijing, China.ResultsDuring the follow-up period, a total of 191 subjects had MACEs. Cox regression analysis showed that sdLDL-C is a major risk factor for MACEs independent of sex, age, BMI, hypertension, diabetes, smoking, SBP, DBP, FBG, eGFR in the general community population (1.013 (1.001 -1.025, P <0.05)), but the correlation disappeared after adjusting for TC and HDL-C in Model 3. Cox analysis showed that hypertension combined with high level of sdLDL-C was still the risk factor for MACEs ((2.079 (1.039-4.148)).ConclusionsOur findings in the Chinese cohort support that sdLDL-C is a risk factor for major adverse cardiovascular events in hypertension subjects.
