Background and Objective. Atherosclerotic extent was proved to be associated with adverse cardiac events. Risk scores derived by coronary computed tomography angiography (CCTA) could identify high-risk group among patients with nonobstructive coronary artery disease (CAD), but the ability is still uncertain in the presence of diabetes mellitus (DM). The purpose of this study was to investigate the prognostic value of the atherosclerotic extent shown by CCTA in diabetic patients with nonobstructive CAD. Methods and Results. 813 DM patients (mean age 58.9 ± 9.9 years, 48.1% male) referred for CCTA due to suspected CAD in 2015-2017 were consecutively included. During a median follow-up of 31.77 months, 50 major adverse cardiovascular events (MACEs) (6.15%) were experienced, including 2 cardiovascular deaths, 14 nonfatal myocardial infarctions, 27 unstable anginas requiring hospitalization, and 7 strokes. Three groups were defined based on coronary stenosis combined with Leiden score as normal, nonobstructive Leiden < 5 , and nonobstructive Leiden ≥ 5 . Cox models were used to assess the prognosis of plaque burden within these groups. An incremental incidence of MACE rates was observed. After adjustment for age, gender, and presence of high-risk plaque, the group of Leiden ≥ 5 showed a higher risk than Leiden < 5 (HR: 1.88, 95% CI: 1.03-3.42, p = 0.039 ). Similar results were observed when segment involvement score (SIS) was used for sensitivity analysis. Conclusion. Atherosclerotic extent was associated with the prognosis of DM patients with nonobstructive coronary artery disease, highlighting the importance of better risk stratification and management.

Background: Cardiovascular disease is a major cause of morbidity and mortality in diabetics. However diabetic patients do not present with typical anginal symptoms or may be even asymptomatic and silent coronary artery disease (CAD) is prevalent in diabetics. Moreover silent CAD is not different from symptomatic CAD with respect to prognosis and adverse effects. Aim: The study was done to demonstrate the prevalence of silent myocardial ischemic changes in asymptomatic type 2 diabetes mellitus patients with normal resting ECG by doing a stress exercise test. Methodology: This descriptive study was done in 100 patients with type 2 diabetes more than 2 years who did not have any history of cardiovascular disease or symptoms. Detailed history was taken and investigations such as HbA1c, fasting and postprandial blood sugar, serum creatinine, urine examination were done. Resting ECG, Echocardiogram was found to be normal and they were subjected to a treadmill test. Results: Among the 100 participants 18 persons (18%) had positive ECG findings in treadmill test. A positive association was found between the duration of diabetes and prevalence of positive treadmill test. Conclusion: There is significant prevalence of silent CAD in diabetic patients and they tend to present with advanced disease at presentation and have poorer prognosis compared to non diabetic population. Hence it is necessary to screen early for silent CAD in diabetics to improve disease outcomes.

Bypass Angioplasty Revascularization Investigation

Background— The Bypass Angioplasty Revascularization Investigation trial demonstrated that symptomatic diabetics with multivessel coronary artery disease had a survival advantage with initial coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI). No published study has examined different treatments and outcome in asymptomatic diabetics. Methods and Results— This study group consisted of 826 asymptomatic diabetics (age 62±12 years; 76% men) without known coronary artery disease who had abnormal myocardial perfusion during stress single photon emission computed tomography (SPECT). SPECT images were classified as low-, intermediate-, and high-risk. Early revascularization (CABG or PCI ≤4 months after SPECT) was performed in 76 patients. Survival (follow-up, 5.3±3.3 years) was compared in patients treated with CABG, PCI, or medical therapy. Revascularization (CABG or PCI) was performed in 54 of 261 patients with high-risk scans and was independently associated with improved survival (χ 2 =4.55; P =0.03 after multivariate adjustment). Subset analysis demonstrated that the survival advantage was confined to patients treated with CABG (n =39), with a 5-year survival CABG at 85%, PCI at 72%, and medical therapy at 67% ( P =0.02 for 3 groups). Although CABG was associated with better survival, mortality remained high (3% per year). There was no survival advantage by treatment for patients with less-severe SPECT abnormalities. Conclusions— These nonrandomized data suggest that CABG improves survival in asymptomatic diabetic patients with high-risk SPECT, although revascularization was performed infrequently in these patients. These results parallel those of the Bypass Angioplasty Revascularization Investigation trial in symptomatic diabetic patients.

Abstract Background and Objective: Atherosclerotic extent was approved to be associated with adverse cardiac events. Risk score derived by coronary computed tomography angiography (CCTA) could identify high-risk group among patients with non-obstructive coronary artery disease (CAD) but its ability is still uncertain in the presence of diabetes mellitus (DM). The purpose of this study was to investigate the prognostic value of the plaque burden shown by CCTA in diabetic patients with non-obstructive CAD.Methods and Results: 813 DM patients (age 58.9±9.9 years, 48.1% male) referred for CCTA due to suspect CAD in 2015-2017 were consecutively included. During a median follow-up of 31.77 months, 50 MACEs (6.15%) were experienced, including 2 cardiovascular deaths, 14 non-fatal myocardial infarction, 27 unstable angina requiring hospitalization and 7 strokes. 3 groups were defined based on coronary stenosis combined with Leidon score, as normal, non-obstructive Leidon<5, and non-obstructive Leidon≥5. Cox models was used to assess the prognosis of plaque burden within these groups. An incremental incidence of outcome event rates was observed. After adjustment for age, gender, and presence of high-risk plaque, the group of Leidon≥5 showed a higher risk than Leidon<5 in non-obstructive CAD (HR:1.88 95%CI:1.03-3.42, p＝0.039). Similar results were illustrated when segment involvement score was used for sensitivity analysis.Conclusion: Atherosclerotic extent was associated with the prognosis of DM patients with non-obstructive coronary disease, highlighting the importance of better risk stratification and management.
