Background: Contrast induced nephropathy (CIN) is a common complication in patients receiving intravascular contrast media. In 2020, the American College of Radiology and the National Kidney Foundation issued a new contrast induced acute kidney injury (CI-AKI) criteria. Therefore, we aimed to explore the potential risk factors for CIN under the new criteria, and develop a predictive model for patients with coronary artery disease (CAD) with relatively normal renal function (NRF).Methods: Patients undergoing coronary angiography or percutaneous coronary intervention at Zhongshan Hospital, Fudan University between May 2019 and April 2020 were consecutively enrolled. Eligible candidates were selected for statistical analysis. Univariate and multivariate logistic regression analyses were used to identify the predictive factors. A stepwise method and a machine learning (ML) method were used to construct a model based on the Akaike information criterion. The performance of our model was evaluated using the area under the receiver operating characteristic curves (AUC) and calibration curves. The model was further simplified into a risk score.Results: A total of 2,009 patients with complete information were included in the final statistical analysis. The results showed that the incidence of CIN was 3.2 and 1.2% under the old and new criteria, respectively. Three independent predictors were identified: baseline uric acid level, creatine kinase-MB level, and log (N-terminal pro-brain natriuretic peptide) level. Our stepwise model had an AUC of 0.816, which was higher than that of the ML model (AUC = 0.668, P = 0.09). The model also achieved accurate predictions regarding calibration. A risk score was then developed, and patients were divided into two risk groups: low risk (total score < 10) and high risk (total score ≥ 10).Conclusions: In this study, we first identified important predictors of CIN in patients with CAD with NRF. We then developed the first CI-AKI model on the basis of the new criteria, which exhibited accurate predictive performance. The simplified risk score may be useful in clinical practice to identify high-risk patients.

Abstract Background The COMPASS trial demonstrated that a combination of rivaroxaban and aspirin improved cardiovascular (CV) outcomes in high-risk patients with either peripheral artery disease (PAD) or stable coronary artery disease (CAD) compared with aspirin alone, at the price of increased bleeding. A previous analysis of the REACH Registry reported an eligibility rate of 52.9% within a population with stable vascular disease. However, most of cardiologists actually treat patients with stable CAD, rather than PAD. Data regarding eligibility to COMPASS in CAD patients from real life practice are scarce. Purpose We aimed to describe the proportion of patients eligible to COMPASS within the CLARIFY Registry. Additionally, we aimed to describe their management and outcomes, comparing patients excluded from the trial (COMPASS Excluded), patients eligible for the trial (COMPASS Eligible), and patients who did not meet the “enrichment criteria” for enrolment (COMPASS Not Included). Methods We used the CLARIFY Registry, an international observational registry of more than 30.000 patients with stable CAD. In accordance with COMPASS exclusion criteria, patients with a REACH bleeding risk score >10, heart failure (HF), severe renal insufficiency, need for dual antiplatelet therapy (DAPT), or anticoagulant (AC) therapy were excluded. Then, COMPASS inclusion criteria were applied: CAD patients had to be 65 years or more, or, if younger, have documented atherosclerosis (PAD or revascularization involving at least two vascular beds) or at least two enrichment criteria (current smoker, diabetes mellitus, GFR <60 mL/min, or non lacunar ischemic stroke).The ischemic outcome was a composite of CV death, MI, or stroke and bleeding outcome was a composite of bleeding leading to either admission or transfusion, or haemorrhagic stroke. Results Among 15.185 patients with comprehensive data allowing precise assessment of eligibility, 43.1% (n=6.540) had at least one exclusion criteria (COMPASS-Excluded), 23.1% (n=3.503) did not have enrichment criteria (COMPASS-Not Included) and 33.9% (n=5.142) were eligible. The vast majority of excluded patients were excluded due to high bleeding risk (62.7% needing DAPT, and 52.7% for high REACH bleeding risk score). The rates (100 patients/year) of ischemic and bleeding outcome were 2.3 [2.1–2.5] and 0.5 [0.4–0.6] respectively for COMPASS-Eligible, 3.0 [2.8–3.2] and 0.6 [0.5–0.7] for COMPASS-Excluded and 1.2 [1.0–1.4] and 0.2 [0.2–0.3] for COMPASS-Not Included. Ischemic and bleeding events Conclusion In a large contemporary registry of stable CAD patients, approximately one of three patients was potentially eligible for adjunction of low-dose rivaroxaban to aspirin. This group is at particularly high risk of ischemic outcome. Patients with exclusion criteria for COMPASS had the worse ischemic and bleeding outcomes and represent a group in need of improved therapy. Acknowledgement/Funding None

Background: Clinical guidelines recommend that optimal management of acute coronary syndrome (ACS) should include patient risk stratification. Predicting the anatomical extension of coronary artery disease (CAD) is also potentially useful for clinical decision. Objective: The objective of our study was to determine whether the TIMI risk score correlates with the angiographic extent and severity of CAD in patients with NSTE- ACS. Materials and Methods: This was a cross-sectional observational study carried out in the Department of Cardiology, Chattogram Medical College Hospital (CMCH) from September 2017 to May 2018. A total of 200 patients diagnosed with NSTE- Acute Coronary Syndrome were included as sample by purposive sampling method. TIMI risk score for each patient was calculated and the patients were stratified into 3 groups according to the TIMI risk score: low risk (0-2); intermediate risk (3-4); high risk (5-7). The severity of the CAD was assessed by Vessel score and Gensini score. Result: The mean ± SD of the age of study population was 53.7 ±10.8 years (range 37–77) and 142 (71%) were male. Regarding cardiovascular risk factors, 137 (68.5%) patients had diabetes mellitus, 83 (41.5%) had dyslipidaemia, 155 (77.5%) had hypertension, 136 (68%) were current smoker and 70 (35%) had a family history of CAD. The Gensini score was higher in patients at high risk TIMI group (p<0.001). Moreover, there was a signiûcant positive correlation between the TIMI and Gensini score (r=0.446,p<0.001). TIMI score can predict significant CAD moderately well (area under the curve 0.661, p=0.001). Patients with TIMI score > 4 were more likely to have significant three vessel CAD (65.9%) versus those with TIMI risk score 3-4 (17.9%) and TIMI risk score < 3 (2%) (p< 0.001). Conclusion: Study showed the TIMI score is significantly correlated with the extent of CAD as assessed by the Gensini score. It is accurate for predicting severe CAD among NSTE-ACS patients.

Abstract Background Assessment of secondary event risk is now recommended for all coronary artery disease (CAD) patients. Many risk calculators have been developed for this purpose. However, their contribution to secondary prevention of CAD is limited because it is unknown whether high-risk patients would benefit more from intensive management. This study sought to apply a previously developed risk score of secondary event to predict readmission in CAD patients, and determine if higher-risk patients benefit more from intensive medical and interventional therapies. Methods This State-wide longitudinal study included 19,940 patients admitted to a hospital in 2010 with CAD as the principal diagnosis. Patients were followed up till the end of 2015. A previously developed and validated risk score (PEGASUS-TIMI54) was used to estimate risks of future adverse events and stratify all patients into either low risk (score&lt;6) or high risk (score≥6) as previously recommended. The primary outcome was all-cause readmission. Secondary outcomes included all-cause mortality and days alive and out of hospital within five years of hospital discharge. Cox proportional hazards regression and linear regression were used for analysis. Results The high risk patients (n=6,573) had a significantly higher proportion of males and Indigenous people, had greater comorbidities, and were more likely to be readmitted or dead (all p&lt;0.001) than their counterparts in the low risk group (n=13,367). Beta-blocker (hazards ratio HR=0.87 [95% CI: 0.79–0.95]), ACEi/ARB (HR=0.68 [95% CI: 0.62–0.73]) and PCI (HR=0.91 [95% CI: 0.88–0.95]) were negatively associated with readmission, and showed a negative interaction (p&lt;0.001) with patients' predicted risks – implicating greater benefits for high-risk patients. CABG, on the contrary, was positively associated with readmission (HR=1.44 [95% CI: 1.15–1.80]) and showed a negative interaction (p&lt;0.001) with patients' predicted risks. This finding suggests that patients receiving CABG were more likely to be readmitted than those not receiving CABG, but this trend reduced for patients with higher risks. Analysis of secondary outcomes suggest that all medical and interventional therapies reduced mortality risks, with the strongest effect size for CABG (HR=0.34 [95% CI: 0.29–0.48]). There was a negative interaction of statins, PCI and CABG with patients' predicted risks, implicating greater survival benefits for patients with higher risks. Conclusions CAD patients can be effectively risk-stratified. The use of this information for a risk-guided strategy may maximize benefits for high-risk patients.

Abstract Cardiovascular disease is the biggest driver of mortality in people with diabetes. Cardiovascular disease and diabetes share the same risk factors, the so-called “common soil” hypothesis. Asians and more specifically Indians are predisposed to cardiovascular disease, that too at an earlier age. The cost of management of cardiovascular disease in India is prohibitive. Thus, screening for asymptomatic coronary artery disease in people with type 2 diabetes and referring them for further evaluation will go a long way in preventing cardiovascular mortality. 560 consenting previously diagnosed people with type 2 diabetes, undergoing treatment for type 2 diabetes at our center, were recruited in the study. We used the risk score model for the assessment of coronary artery disease in asymptomatic patients with type 2 diabetes (1) because it was easy to use, specific for Asian population and validated with coronary computed tomographic angiography in asymptomatic people with type 2 diabetes. Questions regarding smoking, past history of stroke and duration of diabetes were recorded as per the risk score and accordingly the subjects were labelled low, intermediate and high risk. Anthropometric measurements were recorded, lipid profile was measured, neuropathy assessment was done using the DNS score. Results: 48.9%subjects were females,51.1% were males, mean duration of diabetes was 3.5 years, mean HbA1c was 8.5%, mean BMI 26.5kg/m2, mean age was 51.4 years, mean CAD score was 4.1 44.2% of the subjects were in a low risk category, 44.9% were in the intermediate risk category and 10.9% in the high-risk category. The maximum people had intermediate to high risk and were in the age group of 50–60 years (21.3%), followed by 13% in the 60–70 age group. Surprisingly, 12.6% people in the 40-50year age group had an intermediate to high risk score for ASCVD. The high prevalence of intermediate to high risk in relatively younger populations with shorter duration of diabetes (mean duration of diabetes 3.5 years) mandates universal screening for asymptomatic coronary artery disease in all people with type 2 diabetes mellitus. Our study highlights the importance of identifying asymptomatic coronary artery disease using locally relevant risk models and their timely referral to prevent excessive cardiovascular mortality in people with type 2 diabetes mellitus. This would ensure optimum utilization and prioritization of scarce resources in resource crunch situations. Keywords: Screening, asymptomatic CAD, type 2 diabetes mellitus. References: 1.

Coronary artery disease (CAD) is the leading cause of mortality and morbidity worldwide. Left main coronary artery disease (LMCAD) is a severe phenotype of CAD and has a genetic component. Previous studies identified 3 inflammation-related single nucleotide polymorphisms (SNPs) contributing to the development of LMCAD. We integrated these SNPs into a genetic risk score for the prediction of LMCAD. We enrolled 1544 patients with CAD between 2007 and 2011. The individual associations of the 3 SNPs with LMCAD were assessed. We then calculated the genetic risk score for each patient and stratified patients into low-risk, intermediate-risk, and high-risk categories of genetic risk. In univariable logistic regression analysis, the odds of LMCAD for the high-risk group were 2.81 (95% confidence interval [CI]: 1.72-4.60; P = 0.02) times those of the low-risk group. After adjustment for CAD-related clinical variables, the high-risk group (adjusted OR: 2.78; 95% CI: 1.69-4.58; P = 0.02) had increased odds of LMCAD when compared with the low-risk group. Comparison of model c-statistics showed greater predictive value with regard to LMCAD for the genetic risk score model than the models including single SNPs.

Abstract Background Galectin-1 modulates acute and chronic inflammation, and is associated with glucose homeostasis and chronic renal disease. Whether serum Galectin-1 levels could predict the short-term and long-term renal outcomes after contrast exposure in patients with suspected coronary artery disease remains uncertain. Purpose This study aimed to evaluate the relationship between serum Galectin-1 levels and the incidence of contrast-induced nephropathy and to investigate the predictive role of circulating galectin-1 levels in renal function decline in patients undergoing coronary angiography. Methods In total, 798 patients who had received coronary angiography were enrolled. Serum galectin-1 levels were determined before administration of contrast media. Contrast-induced nephropathy was defined as a rise in serum creatinine of 0.5 mg/dL or a 25% increase from baseline within 48 h after the procedure. Progressive renal function decline was defined as >30% decrease in estimated glomerular filtration rate after discharge. All patients were followed up for at least one year or until the occurrence of death after coronary angiography. Results Overall, contrast-induced nephropathy occurred in 41 (5.1%) patients. During a median follow-up of 1.4±1.1 years, 80 (10.0%) cases had subsequent decline in renal function. After adjustment for demographic characteristics, kidney function, traditional risk factors, and medications, higher galectin-1 level was found to be independently associated with a higher risk for mortality and renal function decline (tertile 2, HR=3.12 95% CI,1.25–7.78; tertile 3, HR=3.25, 95% CI,1.42–7.41) but not for contrast-induced nephropathy, regardless of the presence of diabetes. Conclusions Higher baseline serum galectin-1 levels were associated with a higher risk of mortality and renal function decline in patients undergoing coronary angiography. Galectin-1 may play a pivotal role in progressive renal dysfunction, but further studies are needed to verify these results.
