The CYBA gene encodes the regulatory subunit of NADPH oxidase, which maintains the redox state within cells and in the blood vessels. That led us to investigate the course of coronary artery disease (CAD) with regards to CYBA polymorphisms. Thus, we recruited 1197 subjects with coronary atherosclerosis and observed them during 7-year follow-up. Three CYBA polymorphisms: c.214C>T (rs4673), c.-932G>A (rs9932581), and c.*24G>A (1049255) were studied for an association with death, major adverse cardiovascular events (MACE) and an elective percutaneous coronary intervention or coronary artery bypass grafting (PCI/CABG). We found an association between the CYBA c.214C>T polymorphism and two end points: death and PCI/CABG. CYBA c.214TT genotype was associated with a lower risk of death than C allele (9.5% vs. 21%, p < 0.05) and a higher risk of PCI/CABG than C allele (69.3% vs. 51.7%, p < 0.01). This suggests that the CYBA c.214TT genotype may be a protective factor against death OR = 0.47 (95%CI 0.28–0.82; p < 0.01), while also being a risk factor for an elective PCI/CABG OR = 2.36 (95%CI 1.15–4.82; p < 0.05). Thus, we hypothesize that among patients with coronary atherosclerosis, the CYBA c.214TT genotype contributes to atherosclerotic plaque stability by altering the course of CAD towards chronic coronary syndrome, thereby lowering the incidence of fatal CAD-related events.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction There is some evidence suggesting that exaggerated hypertensive response to exercise (HRE) may be associated with higher risk of future cardiovascular events, however the relationship between systolic blood pressure (SPB) during exercise test and stroke is not fully understood. Purpose To evaluate the ability to predict the risk of stroke in patients with HRE in exercise test. Methods Single-center retrospective study of consecutive patients submitted to exercise test from 2012 to 2015 with HRE to stress test. HRE was defined as a peak systolic blood pressure (PSBP) &gt; 210 mmHg in men and &gt; 190 mmHg in women, or a rise of the SBP of 60 mmHg in men or 50 mmHg in women or as a diastolic blood pressure &gt; 90 mmHg or a rise of 10 mmHg. Patient’s demographics, baseline clinical characteristics, vital signs during the stress test and the occurrence of stroke during follow-up were analysed Results We included 458 patients with HRE (76% men, 57.5 ± 10.83 years). The most frequent comorbidities were hypertension (83%), dyslipidaemia (61%), previously known coronary disease (32%), diabetes (28%) and smoking (38%). Atrial fibrillation was present in 5.9% of patients. During a mean follow-up of 60 ± 2 months, the incidence of stroke was 2.1% (n = 8), all with ischemic origin. Considering the parameters analysed on exercise test, only PSBP demonstrated to be an independent predictor of stroke (HR 1.042, CI95% 1.002-1.084, p = 0.039,) with moderate ability to predict stroke (AUC 0.735, p = 0.0016) with a most discriminatory value of 203 mmHg (sensibility 56%, specify 67%). Regarding baseline characteristics, after age, sex and comorbidities adjustment, previously controlled hypertension was found to be an independent protective factor of stroke (OR 4.247, CI 95% 0.05-0.9, p = 0.036) and atrial fibrillation was an independent predictor of stroke occurrence (HR 8.1, CI95% 1.4-46.9, p = 0.018). Atrial fibrillation was also associated with hospitalization of cardiovascular cause and major cardiovascular events occurrence (mortality, coronary syndrome and stroke). Baseline SBP was associated with atrial fibrillation development (p = 0.008). Conclusion According to our results, PSBP during exercise test is an independent predictor of stroke occurrence and should be considered as a potencial additional tool to predict stroke occurrence, particularly in high risk patients. The identification of diagnosed hypertension as a protective factor of stroke may be explained by the cardioprotective effect of antihypertensive drugs.

Abstract Background Emerging evidence indicates increased coronary atherosclerosis in amateur athletes. However, previous studies were limited by its cross-sectional design and limited sample size, preventing the exploration of sport specific associations with coronary atherosclerosis. Purpose We aimed to compare the incidence and progression of coronary artery calcification (CAC) between runners, cyclists and other types of athletes using a prospective cohort study with repetitive measurements. Methods Asymptomatic middle-aged men, who previously underwent a sports medical evaluation without abnormalities, were recruited in the Measuring Athlete's Risk of Cardiovascular events (MARC) study (n=318) and were asked to participate in this follow-up study. CT imaging was performed to assess CAC scores. Data was collected between 2012–2014 (i.e. baseline) and 2019–2020 (i.e. follow-up). We categorized participants as runners, cyclists or “other” sports (e.g. water polo, tennis, hockey, etc.) based on their dominant sport performance at baseline. Results We included 260 men in this interim analysis, with an average follow-up time of 6.3±0.5 years. Age (61.4±6.4 years), systolic blood pressure (143±20 mmHg), BMI (25.2±2.8 kg/m2), LDL-cholesterol (3.2±0.9 mmol/L), smoking (0.3 [0–8] pack years) and family history of coronary heart disease (28%) did not differ between runners (n=64), cyclists (n=75) and other athletes (n=121, all p&gt;0.05). CAC was present in 137 (53%) men at baseline, which increased to 181 (70%) at follow-up. CAC scores increased from 1 [0–33] to 33 [0–129]. Cyclists had a lower CAC prevalence and CAC scores compared to individuals performing other sports at follow-up (Figure 1). Of those without CAC at baseline (n=123, 47%), cyclists less often developed CAC during follow-up compared with runners (adjusted OR=0.36 [0.17–0.79], p=0.01). In the entire cohort, CAC progression (ln delta CAC+1) was less prominent in cyclists than runners (adjusted B=−0.75 [−1.39 to −0.11], p=0.02), whereas progression of CAC in participants performing other sports did not differ from the runners. In participants with CAC at baseline, cyclists also had less CAC progression than runners (B=−0.49 [−0.95 to −0.02], p=0.04). Conclusion Cyclists have a lower incidence and less progression of CAC during 6 years of follow-up compared with runners and individuals performing other sports. Figure 1.

Abstract Objective Insulin resistance has been linked to development and progression of atherosclerosis and is present in most patients with type 2 diabetes. Whether the degree of insulin resistance predicts adverse outcomes in patients with type 2 diabetes and acute coronary syndrome (ACS) is uncertain. Design The Effect of Aleglitazar on Cardiovascular Outcomes after Acute Coronary Syndrome in Patients with Type 2 Diabetes Mellitus trial compared the peroxisome proliferator-activated receptor-α/γ agonist aleglitazar with placebo in patients with type 2 diabetes and recent ACS. In participants not treated with insulin, we determined whether baseline homeostasis model assessment of insulin resistance (HOMA-IR; n = 4303) or the change in HOMA-IR on assigned study treatment (n = 3568) was related to the risk of death or major adverse cardiovascular events (cardiovascular death, myocardial infarction, and stroke) in unadjusted and adjusted models. Because an inverse association of HOMA-IR with N-terminal pro-B-type natriuretic peptide (NT-proBNP) has been described, we specifically examined effects of adjustment for the latter. Results In unadjusted analysis, twofold higher baseline HOMA-IR was associated with lower risk of death [hazard ratio (HR): 0.79, 95% CI: 0.68 to 0.91, P = 0.002]. Adjustment for 24 standard demographic and clinical variables had minimal effect on this association. However, after further adjustment for NT-proBNP, the association of HOMA-IR with death was no longer present (adjusted HR: 0.99, 95% CI: 0.83 to 1.19, P = 0.94). Baseline HOMA-IR was not associated with major adverse cardiovascular events, nor was the change in HOMA-IR on study treatment associated with death or major adverse cardiovascular events. Conclusions After accounting for levels of NT-proBNP, insulin resistance assessed by HOMA-IR is not related to the risk of death or major adverse cardiovascular events in patients with type 2 diabetes and ACS.

Abstract Background: The clinical predictors of inflammation in atherosclerosis remain controversial. The objective of this study was to compare the associations of metabolic factors vs. infectious burden (IB) with inflammation, the severity of coronary atherosclerosis, and major adverse cardiovascular events (MACEs). Design, Setting, and Patients: Coronary angiography with Gensini score was applied to assess the severity of coronary atherosclerosis in 568 patients with coronary artery disease. Metabolic syndrome (MS) score (0–5) was defined according to the modified criteria of National Cholesterol Education Program Adult Treatment Panel III. IB score (0–7) was defined as the number of seropositivities to several agents. Results: IB score was not associated with plasma C-reactive protein (CRP) concentration, Gensini score, or the risk of MACE. In contrast, MS score significantly correlated with both plasma CRP concentration and Gensini score (P &lt; 0.001 for both). MS score and plasma CRP concentration were also significantly associated with the risk of MACE (hazard ratios 1.51, P &lt; 0.001; and 1.90, P = 0.002, respectively). Conclusion: Compared with IB, metabolic abnormalities have a more prominent association with the degree of inflammation, the severity of coronary atherosclerosis, and the risk of MACE in patients with coronary artery disease.

Aim. To assess the long-term results of different approaches to treating patients with non-ST-segment elevation acute coronary syndrome (NSTE ACS) and multivessel coronary artery disease (MVCAD). Subjects and methods. A total of 150 patients with NSTE ACS, in whom coronary angiography revealed MVCAD, were examined. The patients were divided into 3 groups according to the selected treatment policy: 1) percutaneous coronary intervention (PCI) (n=91 (60.6%)); 2) coronary artery bypass grafting (CABG) (n=40 (26.6%)); and 3) only medical treatment (n=9 (6%)). The mean follow-up was 27.6±3.5 months. Results. The medical treatment policy in this patient sample demonstrates the worst results, with the majority of cardiovascular events developing in the hospital period. PCI in patients with NSTE ACS and multiple coronary atherosclerosis has a number of objective limitations in this patient sample, leading to suboptimal treatment outcomes Conclusion. The use of CABG or PCI as a myocardial revascularization technique in patients with NSTE ACS and MVCAD is characterized by a comparable satisfactory survival in the hospital and long-term follow-up periods. 12% of patients do not receive revascularization due to the extremely high risk from any of coronary blood restoring methods, which results in very many deaths largely occurring during the hospital period.

Introduction: Cardiovascular disease and cancer co-exist due to shared risk factors. The utility of coronary artery calcium (CAC) scoring in this population to predict cardiovascular events is not certain. Methods: We studied all patients enrolled in the CLARIFY registry of no-charge CAC (Clinicaltrials.gov NCT04075162) with diagnosis of any cancer. We followed patients for major adverse cardiovascular events (myocardial infarction, stroke, heart failure, coronary revascularization or mortality). Results: A total of 3,432 patients with cancer were identified. Mean age was 64±9 years, 1965 (57%) were women and 2937 (86%) were white. Overall distribution of CAC scores were as follows: CAC 0 in 35%, CAC 1-99 in 31%, CAC 100-399 in 20%, and CAC ≥ 400 in 15%. CAC distribution varied by cancer type (figure A). At a median follow-up of 663 [294-1086] days, 343 patients had MACE event. Compared with CAC 0, patients with CAC ≥ 400 had increased unadjusted risk of MACE (HR 2.57 [1.93-3.41], P<0.001), which was not attenuated after adjusting for age and sex (HR 2.09 [1.50-2.90], P<0.001). Conclusions: In this large cohort of patients with cancer, coronary artery atherosclerotic calcifications are common, vary by cancer type, and are associated with major adverse cardiovascular events, independently of age and sex. Further research should focus on utility of routine CAC for cardiovascular risk stratification in patients with cancer.

Objectives: This study aimed to investigate the relation between ApoE gene polymorphisms and major adverse cardiovascular events (MACE) in patients with acute coronary syndrome (ACS) during a 6-month follow-up. Methods: From October 2016 to July 2017, 211 patients were admitted to a cardiology clinic with a diagnosis of ACS. Blood samples were obtained from all patients on the first day. The primary end point was a 6-month incidence of MACE. ApoE gene polymorphism was genotyped by real-time PCR using TaqMan® SNP Genotyping Assay. Results: The patients with the E4 allele were associated with higher low-density lipoprotein (LDL) cholesterol and total cholesterol (TC) levels compared with the patients without the E4 allele (p = 0001 and p = 0.001). The patients with the E4 allele were associated with a higher rate of MACE compared with the patients without the E4 allele (ApoE4 allele(+) 23.1% vs. ApoE4 allele(−) 9.3%; p = 0.03). Multivariable analysis suggested that E4 allele carriers showed an 85% risk increment of 6-month MACE (odds ratio 2.48, 95% confidence interval 2.37–5.95; p = 0.01). Conclusions: The trial shows that E4 allele carriers were correlated with not only higher LDL cholesterol and TC levels, but also with a higher incidence of MACE during a 6-month follow-up.

Abstract Takotsubo syndrome is a clinical condition characterized by transient impairment of left ventricular contractility, in association with symptoms, increase in indices of myocardial necrosis, as well as electrocardiographic changes, but without a coronary culprit lesion, and often after a significant psychological or physical stress. Albeit very similar to acute coronary syndrome (ACS) as far as presentation and clinical course, Takotsubo syndrome was considered, up until recently, a condition with very favourable long-term prognosis, in view of the frequent complete functional recovery. More recently, several retrospective observational studies as well as registers, unexpectedly called attention to a significant incidence of major adverse cardiovascular events, not limited to the recovery period but also during the long-term follow-up, in a way very similar to the outcome of patients after ACS. Several negative prognostic factors have been isolated, such as physical stress as trigger of the condition, the presence of severe left ventricular dysfunction, and the consequent cardiogenic shock during the acute phase. These factors are able to classify better the patient’s prognosis, both in the short- and long-term, and identify patients requiring a more stringent clinical follow-up, considering the higher likelihood of adverse cardiovascular events.

Background. One of the key concerns of the clinician is to identify and manage risk factors for major adverse cardiovascular events (MACEs) in nondiabetic and diabetic patients with acute coronary syndrome (ACS) undergoing stent implantation. Mean corpuscular volume (MCV) is a marker of erythrocyte size and activity and is associated with prognosis of cardiovascular disease. However, the role of admission MCV in predicting MACEs following stent implantation in diabetes mellitus (DM), non-DM, or whole patients with ACS remains largely unknown. Methods and Results. A total of 437 ACS patients undergoing stent implantation, including 294 non-DM (59.08±10.24 years) and 143 DM (63.02±9.92 years), were analyzed. Admission MCV was higher in non-DM than DM patients. During a median of 31.93 months follow-up, Kaplan-Meier curve demonstrated that higher admission MCV level was significantly associated with increased MACEs in whole and non-DM, but not in DM patients. In Cox regression analysis, the highest MCV tertile was associated with higher MACEs in whole ([HR] 1.870, 95% CI 1.113-3.144, P=0.018), especially those non-DM ([HR] 2.089, 95% CI 1.077-4.501, P=0.029) patients after adjustment of several cardiovascular risk factors. MCV did not predict MACEs in DM patients. During landmark analysis, admission MCV showed better predictive value for MACEs in the first 32 months of follow-up than in the subsequent period. Finally, the receiver operating characteristic (ROC) curve was conducted to confirmed the value of admission MCV within 32 months. Conclusion. In patients with ACS, elevated admission MCV is an important and independent predictor for MACEs following stent implantation, especially amongst those without DM even after adjusting for lifestyle and clinical risk factors. However, as the follow-up period increased, the admission MCV lost its ability to predict MACEs.
