Intramural aortic stenting of an anomalous right coronary artery arising from the left valsalva sinus: A leap into the dark?

A 69-year-old man with unstable angina underwent coronary angiography showing no lesion in the left coronary artery and critical stenosis in the proximal right coronary artery (RCA) arising from the left sinus of Valsalva.

Complete surgical revascularization after NSTEMI and unstable angina in patients with multivessel coronary artery disease: Institutional experience.

INTRODUCTION: The feasibility and standardization of coronary artery bypass grafting (CABG) in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) and unstable angina (UA) remain topics of ongoing debate. In this study, feasibility and early-term outcomes of CABG in patients with NSTE-ACS and UA were discussed. METHODS: This study enrolled 79 patients who underwent on-pump CABG with complete revascularization between January 2020 and May 2022. the survival rates analyzed using Kaplan Meier test with log rank test. The p value of statistical significance was taken as below 0.05. RESULTS: Preoperatively, the patients had a mean age of 60.9 years and a BMI of 28.0. The medical history included hypertension (50.6%), peripheral arterial disease and atrial fibrillation (12.7%), and other comorbidities such as COPD (22.8%) and type 2 diabetes mellitus (44.3%). Intraoperatively, the mean distal anastomosis count was 3.4, with average cardiopulmonary bypass and aortic cross-clamp times of 84.0 and 49.0 min, respectively. Early-term outcomes revealed low rates of mortality (2.5%) and complications such as myocardial infarction (1.3%), acute kidney injury (5.1%) and transient ischemic attack (5.1%). Post-discharge outcomes demonstrated low cardiac and all-cause mortality rates (2.5% and 3.8%, respectively) and a high overall survival rate (93.7%) at 12-month follow-up. CONCLUSION: This study demonstrated the feasibility and positive outcomes of complete surgical revascularization in patients with UA and NSTE-ACS. It showed no graft occlusion or stroke, low complication rates and promising survival outcomes. Further research is needed for confirmation and to establish the procedure's efficacy and safety in this patient population.

Impact of Clinical Presentation on Outcomes After Rotational Atherectomy in Patients Who Underwent Percutaneous Coronary Intervention.

Rotational atherectomy (RA) is widely used in the percutaneous treatment of heavily calcified coronary artery lesions in patients with chronic coronary syndromes (CCS). However, the safety and efficacy of RA in acute coronary syndrome (ACS) is not well established and is considered a relative contraindication. Therefore, we sought to evaluate the efficacy and safety of RA in patients presenting with non-ST-elevation myocardial infarction (NSTEMI), unstable angina (UA), and CCS. Consecutive patients who underwent percutaneous coronary intervention with RA between 2012 and 2019 at a tertiary single center were included. Patients presenting with ST-elevation myocardial infarction (MI) were excluded. The primary end points of interest were procedural success and procedural complications. The secondary end point was the risk of death or MI at 1 year. A total of 2,122 patients who underwent RA were included, of whom 1,271 presented with a CCS (59.9%), 632 presented with UA (29.8%), and 219 presented with NSTEMI (10.3%). Although an increased rate of slow-flow/no-reflow was noted in the UA population (p = 0.03), no significant difference in procedural success or procedural complications, including coronary dissection, perforation, or side-branch closure, was noted (p = NS). At 1 year, there were no significant differences in death or MI between CCS and non-ST-elevation ACS (NSTE-ACS: UA + NSTEMI; adjusted hazard ratio 1.39, 95% confidence interval 0.91 to 2.12); however, patients who presented with NSTEMI had a higher risk of death or MI than CCS (adjusted hazard ratio 1.79, 95% confidence interval 1.01 to 3.17). Use of RA in NSTE-ACS was associated with similar procedural success without an increased risk of procedural complications compared with patients with CCS. Although patients presenting with NSTEMI remained at higher risk of long-term adverse events, RA appears to be safe and feasible in patients with heavily calcified coronary lesions presenting with NSTE-ACS.

Effect of complete percutaneous revascularization on improving long-term outcomes of patients with chronic total occlusion and multi-vessel disease.

BACKGROUND: Limited data are available on the comparison of clinical outcomes of complete vs. incomplete percutaneous coronary intervention (PCI) for patients with chronic total occlusion (CTO) and multi-vessel disease (MVD). The study aimed to compare their clinical outcomes. METHODS: A total of 558 patients with CTO and MVD were divided into the optimal medical treatment (OMT) group ( n = 86), incomplete PCI group ( n = 327), and complete PCI group ( n = 145). Propensity score matching (PSM) was performed between the complete and incomplete PCI groups as sensitivity analysis. The primary outcome was defined as the occurrence of major adverse cardiovascular events (MACEs), and unstable angina was defined as the secondary outcome. RESULTS: At a median follow-up of 21 months, there were statistical differences among the OMT, incomplete PCI, and complete PCI groups in the rates of MACEs (43.0% [37/86] vs. 30.6% [100/327] vs. 20.0% [29/145], respectively, P = 0.016) and unstable angina (24.4% [21/86] vs. 19.3% [63/327] vs. 10.3% [15/145], respectively, P = 0.010). Complete PCI was associated with lower MACE compared with OMT (adjusted hazard ratio [HR] = 2.00; 95% confidence interval [CI] = 1.23-3.27; P = 0.005) or incomplete PCI (adjusted HR = 1.58; 95% CI = 1.04-2.39; P = 0.031). Sensitivity analysis of PSM showed similar results to the above on the rates of MACEs between complete PCI and incomplete PCI groups (20.5% [25/122] vs. 32.6% [62/190], respectively; adjusted HR = 0.55; 95% CI = 0.32-0.96; P = 0.035) and unstable angina (10.7% [13/122] vs. 20.5% [39/190], respectively; adjusted HR = 0.48; 95% CI = 0.24-0.99; P = 0.046). CONCLUSIONS: For treatment of CTO and MVD, complete PCI reduced the long-term risk of MACEs and unstable angina, as compared with incomplete PCI and OMT. Complete PCI in both CTO and non-CTO lesions can potentially improve the prognosis of patients with CTO and MVD.

Revascularization outcomes in diabetic patients presenting with acute coronary syndrome with non-ST elevation.

BACKGROUND: To compare the outcomes of diabetic patients hospitalized with non-ST elevation myocardial infarction (NSTEMI) or unstable angina (UA) referred for revascularization by either coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in a real-life setting. METHODS: The study included 1987 patients with diabetes mellitus enrolled from the biennial Acute Coronary Syndrome Israeli Survey between 2000 and 2016, who were hospitalized for NSTEMI or UA, and underwent either PCI (N = 1652, 83%) or CABG (N = 335, 17%). Propensity score-matching analysis compared all-cause mortality in 200 pairs (1:1) who underwent revascularization by either PCI or CABG. RESULTS: Independent predictors for CABG referral included 3-vessel coronary artery disease (OR 4.9, 95% CI 3.6-6.8, p < 0.001), absence of on-site cardiac surgery (OR 1.4, 95% CI 1.1-1.9, p = 0.013), no previous PCI (OR 1.5, 95% CI 1.1-2.2, p = 0.024) or MI (OR 1.7, 95% CI 1.2-2.6, p = 0.002). While at 2 years of follow-up, survival analysis revealed no differences in mortality risk between the surgical and percutaneous revascularization groups (log-rank p = 0.996), after 2 years CABG was associated with a significant survival benefit (HR 1.53, 95% CI 1.07-2.21; p = 0.021). Comparison of the propensity score matching pairs also revealed a consistent long-term advantage toward CABG (log-rank p = 0.031). CONCLUSIONS: In a real-life setting, revascularization by CABG of diabetic patients hospitalized with NSTEMI/UA is associated with better long-term outcomes. Prospective randomized studies are warranted in order to provide more effective recommendations in future guidelines.

Differences in Revascularization Strategy and Outcomes by Clinical Presentations in Spontaneous Coronary Artery Dissection.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an important cause of myocardial infarction (MI). However, the role of revascularization for SCAD according to presentation remains unclear. METHODS: We analyzed patients with SCAD who presented acutely and were participating in the Canadian SCAD Cohort Study. We compared revascularization strategy and clinical outcomes (in-hospital major adverse events and major adverse cardiovascular event [MACE] including recurrent MI at 1-year) in patients with SCAD presenting with ST-elevation MI (STEMI) vs unstable angina or non-STEMI (UA-NSTEMI). RESULTS: Among 750 patients with SCAD (mean 51.7 ± 10.5years; 88.5% were women; median follow-up was 373 days), 234 (31.2%) presented with STEMI. More patients with SCAD-STEMI (27.8%) were treated with revascularization (98.5% percutaneous coronary intervention [PCI]) compared with 8.7% of patients with UA-NSTEMI (93.3% PCI). For patients with SCAD and STEMI, 93.9% were planned procedures vs 71.1% for UA-NSTEMI. Successful or partially successful PCI was 65.5% for STEMI and 76.9% for UA-NSTEMI (P < 0.001). In revascularized patients, 1-year MACE was not different between STEMI and UA-NSTEMI. Revascularization was associated with higher in-hospital major adverse events and its association was more prominent in UA-NSTEMI (STEMI: 26.2% vs 10.7%, P < 0.001; UA-NSTEMI: 37.8% vs 3.6%, P < 0.001). The difference in adverse events according to revascularization diminished over time and was not evident at 1 year. CONCLUSIONS: Despite higher in-hospital events with revascularization in patients with SCAD, and higher revascularization with SCAD-STEMI, 1-year MACE was not different compared with UA-NSTEMI. This is reassuring, as revascularization may be required for ongoing ischemia at the time of initial presentation in STEMI-SCAD, and emphasizes the need for careful patient selection for revascularization in UA-NSTEMI.

The uric acid to albumin ratio: a novel predictor of long-term cardiac mortality in patients with unstable angina pectoris after percutaneous coronary intervention.

The prognosis of unstable angina pectoris (UAP) differs from non-ST-segment elevation myocardial infarction, and percutaneous coronary intervention (PCI) is considered to improve outcomes of UAP. This study aimed to assess the prognostic value of uric acid to albumin ratio (UAR) for long-term mortality in UAP patients after PCI. Our study retrospectively enrolled 2298 patients hospitalized because of UAP in a tertiary hospital. Divided by medium UAR, the patients were classified into two groups. Baseline demographics, clinical features and laboratory characteristics were obtained from medical records. Post-discharge follow-up was performed either in outdoor clinic or through phone call. The primary endpoint in this study was cardiac death, while all-cause death and rehospitalization were designated as the secondary endpoints. The median follow-up time was 672 days. Among all patients, 58 (2.5%) died, 28 of which died of cardiac deaths (1.2%), and 467 were re-hospitalized (20.3%). Cardiac mortality and all-cause mortality were found to be significantly higher in the high UAR group than in the low UAR group (p = 0.007, p < 0.001), and Kaplan-Meier analysis showed patients with higher UAR may suffer from worse outcomes (p = 0.020). UAR, PCI history, and age were identified as independent predictors of cardiac mortality by multivariate Cox regression. A UAR value of >8.35 was demonstrated as an ideal cut-off point to predict post-PCI cardiac mortality (p <0.001). Overall, it is indicated that baseline UAR was independently correlated with long-term cardiac mortality in patients with UAP treated by PCI.

Effect of Cardiac Rehabilitation Therapy Combined with WeChat Platform Education on Patients with Unstable Angina Pectoris after PCI.

Objective: The aim of this study is to explore the effect of cardiac rehabilitation therapy combined with WeChat platform education on patients with unstable angina pectoris (UAP) after percutaneous coronary intervention (PCI). Methods: Eighty-eight UAP patients undergoing PCI in our hospital from June 2018 to June 2021 were chosen as the study subjects and were grouped according to the intervention methods. Specifically, patients receiving routine treatment only were included as the control group (CG) and those receiving cardiac rehabilitation therapy combined with WeChat platform education based on the routine treatment were included as the study group (SG), with 44 cases in each group. The clinical efficacy was compared between the two groups after intervention. Results: Compared with CG, SG achieved notably better biochemical indexes of TC, TG, FBG, FIB, LDL-c, and HDL-c after 12 months of intervention (P < 0.05), lower systolic pressure (SBP), and diastolic pressure (DBP) after intervention (P < 0.05), and higher scores of limited mobility, anginal stability, anginal frequency, subjective perception, treatment satisfaction, and total SAQ after 12 months of intervention (P < 0.05). The LVEF levels of both groups increased after intervention (P < 0.05), and the LVEF level was higher in SG than in CG (P < 0.05). The incidence of adverse cardiac events such as heart failure, ventricular arrhythmia, and sudden cardiac death was slightly higher in CG than in SG within 12 months of intervention, with no statistical difference (P > 0.05). The UAP recurrence rate and incidence of myocardial infarction in CG were obviously higher than those in SG (P < 0.05). Conclusion: Cardiac rehabilitation therapy combined with WeChat platform education intervention measures for UAP patients after PCI can effectively control the biochemical indexes such as blood lipid and blood glucose, improve the cardiac function, stabilize the disease condition, lower the recurrence rate, and reduce the incidence of other cardiac adverse events.

Impact of Race/Ethnicity on Long Term Outcomes After Percutaneous Coronary Intervention with Drug-Eluting Stents.

Cardiovascular disease constitutes the leading cause of mortality worldwide, irrespective of race/ethnicity. Previous studies have shown that minority patients with acute coronary syndrome have distinct clinical, anatomic, and socioeconomic characteristics which may affect clinical outcomes. We included patients who underwent percutaneous coronary intervention with drug-eluting stents for ST-segment elevation myocardial infarction (STEMI), non-STEMI, or unstable angina in a single center. Patients were stratified into Caucasian, African-American, Hispanic, and Asian. Caucasians were the reference group. The primary end point was major adverse cardiac and cerebrovascular events, composite of death, spontaneous myocardial infarction, or stroke at 1 year. Of 6,800 patients included, 49.7% were Caucasian, 20.7% Hispanic, 17.0% Asian and 12.6% African-American. Caucasians were the oldest, Hispanics and Asians had the highest prevalence of diabetes mellitus whereas African-Americans had more chronic kidney disease. Hispanics and African-Americans had the highest STEMI rates, whereas Asians were more likely to present with unstable angina. Compared with Caucasians, Asians had a lower rate of major adverse cardiac and cerebrovascular events at 1 year (3.9% vs 7.1%; p <0.01) whereas Hispanics (6.2% vs 7.1%; p = 0.17) and African-Americans (8.0% vs 7.1%; p = 0.38) had comparable outcomes. Differences were driven by mortality. Findings remained unchanged after adjustment. In conclusion, in acute coronary syndrome patients who underwent percutaneous coronary intervention, Asian race/ethnicity was associated with favorable cardiovascular outcomes compared with Caucasians. No significant differences were observed for Hispanics and African-Americans.

Burden and Predictors of Chest Pain-Related Health-Care Utilization Following Percutaneous Coronary Intervention.

Chest pain (CP) has been reported in 20% to 40% of patients 1 year after percutaneous coronary intervention (PCI), though rates of post-PCI health-care utilization (HCU) for CP in nonclinical trial populations are unknown. Furthermore, the contribution of noncardiac factors - such as pulmonary, gastrointestinal, and psychological - to post-PCI CP HCU is unclear. Accordingly, the objectives of this study were to describe long-term trajectories and identify predictors of post-PCI CP-related HCU in real-world patients undergoing PCI for any indication. This retrospective cohort study included patients receiving PCI for any indication from 2003 to 2017 through a single integrated health-care system. Post-PCI CP-related HCU tracked through electronic medical records included (1) office visits, (2) emergency department (ED) visits, and (3) hospital admissions with CP or angina as the primary diagnosis. The strongest predictors of CP-related HCU were identified from >100 candidate variables. Among 6386 patients followed an average of 6.7 years after PCI, 73% received PCI for acute coronary syndrome (ACS), 19% for stable angina, and 8% for other indications. Post-PCI CP-related HCU was common with 26%, 16%, and 5% of patients having ≥1 office visits, ED visits, and hospital admissions for CP within 2 years of PCI. The following factors were significant predictors of all 3 CP outcomes: ACS presentation, documented CP >7 days prior to the index PCI, anxiety, depression, and syncope. In conclusion, CP-related HCU following PCI was common, especially within the first 2 years. The strongest predictors of CP-related HCU included coronary disease attributes and psychological factors.

Flow reserve fraction: the optimal choice in lesion assessing and interventional guiding for patient with unstable angina pectoris and intermediate lesion wrapped with myocardial bridge: a case report.

BACKGROUND: It is difficult to choose correctly interventional strategy for coronary intermediate lesions combined with myocardial bridge. Endovascular imaging is advocated to guide treatment, but flow reserve fraction (FFR) is not recommended to guide the interventional treatment of myocardial bridge disease because of the inaccurate judgment misled by myocardial bridge. CASE PRESENTATION: In this study, we reported a case of a 56-year-old male patient with unstable angina pectoris (UAP). From his coronary angiography, we found diffuse stenosis near the midsection of the left anterior descending (LAD) branch and the presence of a severe myocardial bridge in the lesion area. We were sure that the LAD was culprit vessel and this lesion was culprit lesion. Both FFR and intravenous ultrasound (IVUS) were performed and the conclusions of them are different. Although stent implantation is not usually recommended in the myocardial bridge area. However, after careful examination, a stent was finally implanted under the precise guidance of FFR. And the patient recovered well up-to now. CONCLUSIONS: This case illustrates that FFR functional test was complimentary to intravascular imaging test for the coronary intermediate lesion, especially the lesion wrapped with myocardial bridges, both in assessing the lesion and in guiding treatment.

Comparison of multiple risk scores in assessing medium-to long-term clinical outcomes in unstable angina / non-ST-elevation myocardial infarction patients undergoing multi vessel percutaneous coronary intervention: An observational, registry-based study in India.

OBJECTIVE: Post-revascularization mortality in multivessel coronary artery disease (MVCAD) has been explored via several risk scores. Here, we assessed and compared various risk scores in predicting medium to long-term clinical outcomes in unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI) patients with MVCAD undergoing percutaneous coronary intervention (PCI). METHODS: We analyzed a cohort of a tertiary care center registry enrolling patients in South India, Kerala, with MVCAD (N = 200) who had undergone PCI between 2010 and 2018. The outcomes evaluated were all-cause mortality and major adverse cardiac events (MACE). The risk scores assessed included SYNTAX score (SS), residual SYNTAX score (rSS), SYNTAX revascularization index (SRI), age, creatinine, and ejection fraction (ACEF) score, clinical SYNTAX score (cSS), and SYNTAX score II (SSII). RESULTS: Of the analyzed risk scores, SSII had the best predictive capability with the area under the curve (AUC) of 0.79 in c-statistics, followed by ACEF score and cSS with AUCs of 0.74 and 0.65, respectively for all-cause mortality (p < 0.01). Kaplan-Meier survival curves and multivariate analysis by Cox regression showed SSII with cut-offs of >35.15 and > 29.55 to be the only score associated with higher mortality and MACE, respectively. CONCLUSIONS: In UA/NSTEMI patients with relatively less complex MVCAD treated by PCI, the SSII, ACEF and cSS risk scores could predict the outcomes better. The SSII showed the best predictive performance for all-cause mortality and MACE. Scores based on baseline and residual atherosclerotic burden (SS, rSS, and SRI) performed poorly in predicting the mortality and MACE.

High-Risk Percutaneous Coronary Intervention of Native Coronary Arteries Without Mechanical Circulatory Support in Acute Coronary Syndrome Without Cardiogenic Shock.

Widespread utilization of mechanical circulatory support (MCS) for high-risk percutaneous coronary intervention (PCI) remains controversial, with a lack of randomized supporting evidence and associated risk of device-related complications. We investigated whether high-risk PCI of native coronary arteries without elective MCS in patients with acute coronary syndrome (ACS) is safe and feasible. We performed a single-center, retrospective analysis for ACS patients meeting American College of Cardiology high-risk criteria: unprotected left main disease, last remaining conduit, ejection fraction <35%, 3-vessel coronary artery disease, severe aortic stenosis, or severe mitral regurgitation. Patients with cardiogenic shock and those undergoing PCI of the bypass grafts were excluded. Major in-hospital and 30-day cardiovascular outcomes were assessed. From 2003 through 2018, 499 patients (847 lesions) with unstable angina pectoris (UAP), 1218 patients (1807 lesions) with non-ST-elevation myocardial infarction (NSTEMI), and 868 patients (1260 lesions) with ST-segment elevation myocardial infarction (STEMI) underwent high-risk PCI. Procedural success was achieved in 97.2% of UAP, 98.3% of NSTEMI, and 96.6% of STEMI patients. In-hospital and 30-day all-cause mortality were as follows: UAP, 2%; NSTEMI, 2.1%; and STEMI 4.7%. Bailout intra-aortic balloon pump was required in 1.6% of UAP, 3.1% of NSTEMI, and 10.3% of STEMI patients. Major complications for UAP, NSTEMI, and STEMI were, respectively: target lesion revascularization (2.3%, 1.4%, and 1.5%), stroke or transient ischemic attack (0.8%, 0.6%, and 1.3%), acute renal failure (8.2%, 7.2%, and 10.2%), major bleeding (1.6%, 3.1%, and 8.5%). In conclusion, our results show that high-risk PCI without elective MCS is safe and feasible in most ACS patients, challenging professional societies' current recommendations. A randomized trial comparing unprotected versus protected high-risk PCI for non-shock ACS patients is warranted.

Comparison of Long-Term Outcomes Following Coronary Revascularization in Men-vs-Women with Unprotected Left Main Disease.

Gender differences have been recognized in several aspects of coronary artery disease (CAD). However, evidence for gender differences in long-term outcomes after left main coronary artery (LMCA) revascularization is limited. We sought to evaluate the impact of gender on outcomes after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for unprotected LMCA disease. We evaluated 4,320 patients with LMCA disease who underwent CABG (n = 1,456) or PCI (n = 2,864) from the Interventional Research Incorporation Society-Left MAIN Revascularization registry. The primary outcome was a composite of death, myocardial infarction (MI), or stroke. Among 4,320 patients, 968 (22.4%) were females and 3,352 (77.6%) were males. Compared to males, females were older, had a higher prevalence of hypertension and insulin-requiring diabetes, more frequently presented with acute coronary syndrome, but had less extensive CAD and less frequent left main bifurcation involvement. The adjusted risk for the primary outcome was not different after PCI or CABG in females and males (hazard ratio [HR] 1.09; 95% confidence interval [CI]: 0.73-1.63 and HR 0.97; 95% CI: 0.80-1.19, respectively); there was no significant interaction between gender and the revascularization strategy (P for interaction = 0.775). In multivariable analysis, gender did not appear to be an independent predictor for the primary outcome. In revascularization for LMCA disease, females and males had a comparable primary composite outcome of death, MI, or stroke with either CABG or PCI without a significant interaction of gender with the revascularization strategy.

Comparison of Long-Term Outcomes in Men versus Women Undergoing Percutaneous Coronary Intervention.

There has been a significant decrease in mortality associated with coronary artery disease (CAD) in recent decades, although at discordant rates between men and women. Using a well-established multicenter registry, we sought to examine the impact of gender on long-term mortality stratified by indication for percutaneous coronary intervention (PCI). Data from 54,440 consecutive patients (12,805, 23.5% women) undergoing PCI from the Victorian Cardiac Outcomes Registry (2013 to 2018) were analyzed. We aimed to compare gender-related differences of patients undergoing PCI for stable angina pectoris (SAP), non-ST-elevation acute coronary syndrome (NSTEACS) and ST-elevation myocardial infarction (STEMI). The primary outcome was long-term all-cause mortality. Female patients were older across all indications (SAP: 67 vs 71 years, NSTEACS: 64 vs 69 years, STEMI 61 vs 67 years; p value for all <0.001), with age-adjusted higher rates of diabetes mellitus (p value for all <0.02) and renal impairment (p value for all <0.001), and were more likely to have femoral artery access for intervention (p value for all <0.001). Unadjusted in-hospital and 30-day mortality rates were comparable between men and women across all indications. Compared to men, women had a higher rate of unadjusted long-term mortality (9.0% vs 7.37%; p <0.001). However, after adjusting for variables significant on univariate analysis, female gender was independently associated with improved long-term survival (HR 0.76, 95% CI 0.66 to 0.87; p <0.001). In conclusion, contrary to previous studies, despite being older with a differing clinical profile and interventional approach, women undergoing PCI have a long-term survival advantage.

Epicardial adipose tissue volume predicts long term major adverse cardiovascular events in patients with Type 2 diabetes.

OBJECTIVE: Epicardial adipose tissue (EAT) is a metabolically active visceral fat depot that plays an important role in coronary atherosclerosis. In this study, our aim was to investigate the relationship between long-term major adverse cardiovascular events (MACEs) and EAT volume detected by coronary computed tomography angiography (CCTA) in patients with Type 2 diabetes mellitus (T2-DM) without previous coronary events. METHODS: A total of 127 patients with diabetes who underwent CCTA between 2012 and 2014 were enrolled retrospectively. The study population was divided into 2 groups according to whether they experienced or did not experience MACE, which was defined as cardiac death, non-fatal myocardial infarction or unstable angina requiring hospitalization, coronary revascularizations (percutaneous coronary intervention or coronary artery bypass grafting surgery), heart failure, peripheral arterial disease, or ischemic stroke. In both groups, EAT volumes were measured by CCTA. RESULTS: During 60±7 months follow-up period, 22 participants experienced MACEs. Data were evaluated with univariate and multivariate analyses and receiver operating characteristic (ROC) analysis. Age, male sex, coronary artery disease, hemoglobin A1c, glucose, creatinine, C- reactive protein, and cholesterol levels were found to be associated with MACE. EAT volume (odds ratio [OR]: 1.027; 95% confidence interval [CI]: 1.010‒1.044, p=0.002) and low-density lipoprotein (OR: 1.015; 95% CI: 1.000‒1.030, p=0.050) were found to be independent predictors for MACE. ROC analysis indicated that EAT volumes >123.2 mL had a 72.7% sensitivity and a 77.1% specificity for predicting long-term MACE in patients with T2-DM (area under the curve: 0.820; 95% CI: 0.733-0.908). CONCLUSION: EAT volume is an independent predictor of long-term MACE in patients with T2-DM without previous coronary events. EAT volume may be used additionally in risk stratification for MACE besides the well-known vascular risk factors in patients with T2-DM.
