Abstract Background Coronary artery ectasia (CAE) bears high risk of death and myocardial infarction. Risk stratification in CAE patients is crucial for their management, but there were no risk score systems intended for risk evaluation of CAE patients so far. Methods In a retrospective cohort of 595 patients with CAE, we collected the baseline characteristics (clinical history, biomarkers and quantitative coronary angiography variables). Follow-up were conducted and the end-point event was the composite of all-cause death and non-fatal myocardial infarction. The candidate predictors of end-point event were analyzed using Cox proportional hazards regression models to derive a risk score in the form of nomogram. The predictive performance and discriminative ability of the novel nomogram were determined by concordance index (C-index) and calibration curve, that were validated internally. Risk stratification by nomogram-predicted risk score was further evaluated. Results During a median follow-up time of 62.3 months, 26 all-cause deaths and 37 non-fatal myocardial infarctions were identified. The final risk-prediction model named ABCD-CAE score included four items: age (A), Brain natriuretic peptide (B), high sensitivity C-reactive protein (C) and maximum Dilated area of ectatic lesions (D). The nomogram yielded a C-index for end-point event of 0.72 (95% confidence interval, 0.64 - 0.79). The calibration curve demonstrated that there is good agreement between prediction by nomogram and actual observation of end-point events. Compared with the low-risk group (score ≤100), the risk of composite events was significantly increased in the intermediate-risk group (score: 100–130) and high-risk group (score >130) [hazard ratio (95% confidence interval): 2.23 (1.23–4.06), P=0.008 and 7.02 (3.81–12.97), P<0.001 respectively]. ABCD-CAE nomogram for risk prediction Conclusions The ABCD-CAE score is a simple four-item risk score, that provides a clinically useful tool for the risk prediction of all-cause death and myocardial infarction in patients with CAE. This user-friendly tool might support clinical decision making for the management of CAE.

Abstract Background There is existing evidence to suggest a correlation between coronary artery calcification (CAC) measured using ECG-triggered chest computed tomography and cardiovascular disease. Further evidence has emerged to suggest a correlation between CAC measured using non-gated CT scans and cardiovascular disease. Herein, we sought to ascertain the utility of incidental findings of CAC on non-triggered high resolution CT (HRCT) thorax used for patients undergoing lung cancer screening or follow-up for interstitial lung disease and Framingham risk score (FRS) in predicting cardiovascular events. Methods The Computerised Radiology Information Service (CRIS) database was manually searched to determine all HRCT scans performed in a single trust from 05/2015 to 05/2016. The reports issued by Radiologists and images of selected studies were reviewed. For patients with CAC, we calculated the calcium score for patients using the Agatston method. Clinical events were determined from the electronic medical record without knowledge of patients' CAC findings. For these patients, the Framingham Risk Score (FRS) was also calculated. The primary end point of the study was composite of all-cause mortality and cardiac events (non-fatal myocardial infarction, coronary revascularization, new atrial fibrillation or heart failure episode requiring hospitalization). Results We selected 300 scans from a total of approximately 2000 scans performed over this time. Data at follow up was available for 100% of the patients, with a median duration of follow up of 1.6 years. Moderate to severe CAC was found in 35% of people. Multivariable analysis showed good concordance between CAC and FRS in predicting composite clinical end point. The Odds Ratio for cardiac events in patients with moderate to severe CAC was 5.3 (p&lt;0.01) and for composite clinical end point was 3.4 (p&lt;0.01). This is similar to the OR predicted by the FRS: 4.8; p&lt;0.01 and 3.1; p&lt;0.01 respectively. Only 6.2% of patients with moderate to severe CAC were currently statin treated. Conclusion In this retrospective study of patients with respiratory disease attending for HRCT scanning, co-incidentally detected CAC predicts cardiac events, with good concordance with the FRS. The incidental finding of CAC on non-gated CT scanning should be reported with Agatston score calculation allowing consideration of intervention to mitigate cardiovascular risk and optimize. Further multi-centre prospective studies of this strategy, with a larger patient cohort should be conducted to clarify the utility of CAC as a prediction tool to modify cardiac risk.

Aim. We aimed to study in real clinical practice the clinical and anamnestic characteristics, the peculiarities of double antiplatelet therapy (DAPT) prescription as well the incidence of ischemic and hemorrhagic events in patients with ST-elevated myocardial infarction (MI) during a year of follow-up, taking into account the baseline PRECISE-DAPT scores.Material and methods. The study included 680 patients with MI from the database of Kemerovo observational registry for acute coronary syndrome (ACS). All the patients retrospectively underwent an individual calculation using the PRECISE-DAPT score. Then, depending on the number of the points, all the patients were divided into the low (less than 25 points) and high (25 or more points) risks groups. Differences in clinical and anamnestic parameters, the peculiarities of DAPT prescription, as well as the incidence of ischemic and hemorrhagic outcomes during a year of follow-up after MI were estimated in the groups.Results. The Russian patients with ST-elevated MI and the high PRECISE-DAPT hemorrhagic risk score had a history of renal pathology (р=0.010), multivessel coronary artery disease and polyvascular disease (р=0.002), prior angina pectoris (р=0.001), as well as the course of the index event with the manifestations of acute coronary failure (р=0.001) more often than the patients from the low-risk group. The patients of the high-risk group less often underwent coronary angiography with stenting (р=0.001), as well as coronary artery bypass grafting (р=0.010) at hospitalization and had a higher in-hospital mortality rate (р=0.002). The patients at high hemorrhagic risk according to the PRECISE-DAPT score were less often prescribed with DAPT within a year after MI (р=0.001) and aspirin monotherapy was preferred more often (р=0.001). At the same time, the patients at high hemorrhagic risk on the PRECISE-DAPT score had more often major bleedings, recurrent MI and deaths (р=0.001) within a year after MI.Conclusion. In the present study, the possibilities of risk assessment with the PRECISE-DAPT score were retrospectively tested on the sample of patients with MI from the ACS registry in Kemerovo city. Good identification of patients with the high risks of hemorrhagic events and ischemic outcomes within 12 months of the follow-up after index MI has been shown, which allows to recommend the PRECISE-DAPT score for a clinical practice in order to rationalize the approaches to DAPT prescription and to optimize the existing approaches to the comprehensive risk assessment of patients with ACS along with existing scales.

Abstract Background: The CADILLAC risk score was developed to identify patients at low risk for adverse cardiovascular events following ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PPCI). Methods: We performed a single center retrospective review of STEMI hospitalizations treated with PPCI from 2014 to 2018. Patients were stratified using the CADILLAC risk score into low risk group versus intermediate to high risk group. Patients presenting with cardiac arrest or cardiogenic shock were excluded from the study. The primary outcome was adverse clinical events during initial hospitalization. Secondary outcomes were adverse clinical events at 30 days and 1 year following index hospitalization. Results: The study included 314 patients. It was found that patients with a low CADILLAC score had significantly lower adverse clinical events compared to the intermediate-high CADILLAC score group (10/213 (4.7%) vs. 15/128 (11.7%), odds ratio = 0.37, 95% CI 0.16-0.85, p= 0.028). Additionally, patients with a low CADILLAC score had significantly lower adverse clinical event rates at 30 day and 1 year follow up. The mortality rate was 0% for patients defined at low risk by CADILLAC score during hospitalization, as well up to 1 year follow up. ROC curve predicting in hospital event rate showed CADILLAC (C=0.66, odds ratio 1.18; 95% CI 1.04 - 1.33; p=0.0064). Conclusion: Patients defined as low risk by the CADILLAC score following a STEMI were associated with lower event rates when compared to those with an intermediate-high CADILLAC score.

Background: Clinical guidelines recommend that optimal management of acute coronary syndrome should include patient risk stratification. Predicting the anatomical extension of coronary artery disease is also potentially useful for clinical decision. The objective of our study is to determine whether the GRACE risk score correlates with the angiographic extent and severity of coronary artery disease in patients with ST elevation myocardial infarction.Methodology: 50 patients diagnosed with Acute Myocardial Infarction were included as sample by purposive sampling method. GRACE risk score for each patient was calculated and the patients were divided into groups according to the GRACE risk score: low risk (<108); intermediate risk (109-140). The severity of the coronary artery disease was assessed by vessel score and Gensini score. Relation between Grace score and Gensini score was evaluated.Results: Mean GRACE score of study population was 128.3±22.7. Mean Gensini score was 23.88±17. Mean Gensini score were 15.47±10.4, 27.75±9.26 and 31.52±16.91 in low GRACE risk group, intermediate group and high risk group respectively and the difference of mean Gensini score was statistically significant (p=0.006). In our study correlation co-efficient between GRACE risk score and Gensini score was r=0.17 (p=0.04). Multiple regression analysis showed that age more than 50 years (p=0.02), ST segment deviation (p=0.01), smoking (p=0.02), hypertension (p=0.01) were able to independently predict patients with severe CAD.Conclusion: Our study demonstrates that the GRACE risk score carries a significant positive correlation with the coronary artery disease severity in patients with STEMI.Cardiovasc. j. 2015; 8(1): 30-34

AbstractCirculating microRNAs (miRNAs) could improve colorectal cancer (CRC) risk prediction. Here, we derive a blood-based miRNA panel and evaluate its ability to predict CRC occurrence in a population-based cohort of adults aged 50–75 years. Forty-one miRNAs are preselected from independent studies and measured by quantitative-real-time-polymerase-chain-reaction in serum collected at baseline of 198 participants who develop CRC during 14 years of follow-up and 178 randomly selected controls. A 7-miRNA score is derived by logistic regression. Its predictive ability, quantified by the optimism-corrected area-under-the-receiver-operating-characteristic-curve (AUC) using .632+ bootstrap is 0.794. Predictive ability is compared to that of an environmental risk score (ERS) based on known risk factors and a polygenic risk score (PRS) based on 140 previously identified single-nucleotide-polymorphisms. In participants with all scores available, optimism-corrected-AUC is 0.802 for the 7-miRNA score, while AUC (95% CI) is 0.557 (0.498–0.616) for the ERS and 0.622 (0.564–0.681) for the PRS.

AbstractThe purpose of this study was to assess early and late vascular healing in response to bioresorbable-polymer sirolimus-eluting stents (BP-SESs) for the treatment of patients with ST-elevation myocardial infarction (STEMI) and stable coronary artery disease (CAD). A total of 106 patients with STEMI and 101 patients with stable-CAD were enrolled. Optical frequency-domain images were acquired at baseline, at 1- or 3-month follow-up, and at 12-month follow-up. In the STEMI and CAD cohorts, the percentage of uncovered struts (%US) was significantly and remarkably decreased during early two points and at 12-month (the STEMI cohort: 1-month: 18.75 ± 0.78%, 3-month: 10.19 ± 0.77%, 12-month: 1.80 ± 0.72%; p < 0.001, the CAD cohort: 1-month: 9.44 ± 0.78%, 3-month: 7.78 ± 0.78%, 12-month: 1.07 ± 0.73%; p < 0.001 respectively). The average peri-strut low-intensity area (PLIA) score in the STEMI cohort was significantly decreased during follow-up period (1.90 ± 1.14, 1.18 ± 1.25, and 1.01 ± 0.72; p ≤ 0.001), whereas the one in the CAD cohort was not significantly changed (0.89 ± 1.24, 0.67 ± 1.07, and 0.64 ± 0.72; p = 0.59). In comparison with both groups, differences of %US and PLIA score at early two points were almost disappeared or close at 12 months. The strut-coverage and healing processes in the early phase after BP-SES implantation were significantly improved in both cohorts, especially markedly in STEMI patients. At 1 year, qualitatively and quantitatively consistent neointimal coverage was achieved in both pathogenetic groups.

Abstract Background The recent reperfusion therapy for ST-elevation myocardial infarction (STEMI) has made the length of hospital stay shorter without adverse events. CADILLAC risk score is reportedly one of the risk scores predicting the long-term prognosis in STEMI patients. Purpose To invenstigate the usefulness of CADILLAC risk score for predicting short-term outcomes in STEMI patients. Methods Consecutive patients admitted to our university hospital and our medical center with STEMI (excluding shock, arrest case) who underwent primary PCI between January 2012 and April 2018 (n=387) were enrolled in this study. The patients were classified into 3 groups according to the CADILLAC risk score: low risk (n=176), intermediate risk (n=87), and high risk (n=124). Data on adverse events within 30 days after hospitalization, including in-hospital death, sustained ventricular arrhythmia, recurrent myocardial infarction, heart failure requiring intravenous treatment, stroke, or clinical hemorrhage, were collected. Results In the low risk group, adverse events within 30 days were significantly less observed, compared to the intermediate and high risk groups (n=13, 7.4% vs. n=13, 14.9% vs. n=58, 46.8%, p&lt;0.001). In particular, all adverse events occurred within 3 days in the low risk group, although adverse events, such as heart failure (n=4), recurrent myocardial infarction (n=1), stroke (n=1), and gastrointestinal bleeding (n=1), were substantially observed after day 4 of hospitalization in the intermediate and high risk groups. Conclusions In STEMI patients with low CADILLAC risk score, better short-term prognosis was observed compared to the intermediate and high risk groups, and all adverse events occurred within 3 days of hospitalization, suggesting that discharge at day 4 might be safe in this study population. CADILLAC risk score may help stratify patient risk for short-term prognosis and adjust management of STEMI patients.

Abstract Background Drug-coated balloon has been widely used to treat In-Stent Restenosis as recommended by ESC/EACT coronary intervention guideline. However, trials of effectiveness of DCB in treating de novo lesions in diabetic patients are limited. This study will highlight the impact of DCB in diabetic patients with only de novo lesions against non-diabetic patients. Aim To compare the outcomes of Paclitaxel Drug Coated Balloon (DCB) in Diabetic and non-diabetic patients with only de novo coronary artery disease. Methods A retrospective, single center study was conducted from January 2016 till December 2018. All diabetic and non-diabetic patients underwent angioplasty to only de novo coronary artery lesions were included in the study. Patients' baseline characteristic, angiographic data, post procedural and 12 months follow-up outcomes including major adverse coronary artery event (MACE), target lesion revascularization (TLR) and myocardial infarction (MI) are compared. Results A total of 1257 patients (726 diabetic and 531 non-diabetic patients) with total 1385 de novo coronary artery lesions (791 lesions in diabetic group and 594 lesions in non-diabetic group) were included in this study. Mean age for non-diabetic group was 57.6±10.6 years and diabetic group was 59.6±9.6 years with male predominance (91.1% in non-diabetic group, n=484 and 79.2% in diabetic group, n=575). Majority of diabetic group has hypertension (83.7%, n=608 vs 58.6%, n+311), chronic renal failure (10.3%, n=75 vs 1.9%, n=10), documented coronary artery disease (55.6%, n=404 vs 47.5%, n=252) and previous coronary angioplasty 39.5%, n=287 vs 28.8%, n=153). Adequate pre-dilatation was done in both groups (98.5%, n=585 in non-diabetic group and 99.4%, n=786 in diabetic group; p=0.000). Mean DCB diameter and length were almost similar in both groups. Mean residual stenosis after DCB was 11.15±16.9% in non-diabetic group and 13.13±13.4% in the diabetic group (p=0.008). 74.6% of non-diabetic group (n=396) and 77.1% of diabetic group (n=560) were on double antiplatelet therapy for 12 months. 86.8% (n=461) of non-diabetic and 88.4% (n=642) of diabetic patients were available for follow up. MACE events were significantly higher (p=0.000) in diabetic group (4.3%, n=31) as compare to non-diabetic group (0.6%, n=3). Target lesion revascularization (TLR) and myocardial infarction (MI) was also significantly higher in diabetic group (TLR 1.4%, N=10 vs 0.6%, n=3, p=0.049; MI 2.6%, n=19 vs 0.4%, n=2, p=0.002). Conclusion Treating de novo coronary lesions in diabetic patients with DCB associated with significantly higher MACE events, target lesion revascularization and myocardial infarction. Diabetic patients appear to have a greater volume of atherosclerotic plaque and increased propensity for atherosclerotic plaque rupture. Funding Acknowledgement Type of funding source: None

Background —Although coronary angioplasty and myocardial bypass surgery are routinely used, there is no conclusive evidence that these interventional methods offer greater benefit than medical therapy alone. This study is intended to evaluate, in a prospective, randomized, and comparative analysis, the benefit of the 3 current therapeutic strategies for patients with stable angina and single proximal left anterior descending coronary artery stenosis. Methods and Results —In a single institution, 214 patients with stable angina, normal ventricular function, and severe proximal stenosis (>80%) on the left anterior descending artery were selected for the study. After random assignment, 70 patients were referred to surgical treatment, 72 to angioplasty, and 72 to medical treatment. The primary end points were the occurrence of acute myocardial infarction or death and presence of refractory angina. After a 5-year follow-up, these combined events were reported in only 6 patients referred to surgery as compared with 29 patients treated with angioplasty and 17 patients who only received medical treatment ( P =0.001). However, no differences were noted in relation to the occurrence of cardiac-related death in the 3 treatment groups ( P =0.622). No patient assigned to surgery needed repeat operation, whereas 8 patients assigned to angioplasty and 8 patients assigned to medical treatment required surgical bypass after the initial random assignment. Surgery and angioplasty reduced anginal symptoms and stress-induced ischemia considerably. However, all 3 treatments effectively improved limiting angina. Conclusions —Bypass surgery for single-vessel coronary artery disease is associated with a lower incidence of medium-term and long-term events as well as fewer anginal symptoms than that found in the patients who underwent angioplasty or medical therapy. In this study, coronary angioplasty was only superior to medical strategies in relation to the anginal status. However, the 3 treatment regimens yielded a similar incidence of acute myocardial infarction and death. Such information should be useful when choosing the best therapeutic option for similar patients.
