Abstract Background Dypiridamol stress echocardiography (DSE) is an important tool for detecting reversible ischemia in patients with suspected coronary artery disease (CAD); nonetheless the results of the test are related to visualization of wall motion abnormalities, moderately operator-dependent, and left anterior descending (LAD) artery reserve, resulting in a moderate sensibility and specificity. Aim of our study was to evaluate whether an an easy-to-use parameter like mitral annular plane systolic excursion (MAPSE) could be useful to identify CAD during DSE. Methods We prospectively enrolled 300 patients with suspected CAD and perform a DSE; at rest and peak MAPSE was acquired. 59 patients with reversibile ischemia during stress echocardiography (positive) were referred to perform coronary angiography. Patients were divided according to MAPSE behaviour during DSE: group 1 (MAPSE ≤ 0) and group 2 (delta MAPSE > 0 mm). Results The mean age of was 63 ± 11 years, male gender was prevalent (73%); no differences were found in risk factors and left vetnricular ejection fraction (LV-EF) between two groups.Coronary arteries were normal in 14 patients (23%), while significant stenosis (>70%) was found in 45 patients (77%); in 31 patients (53%) left main (LM) or proximal LAD artery were involved, while in 17 (29%) and 22 (37%) right coronary artery and circumflex artery were affected respectively. Patients with CAD showed a lower (blunted or no increase) MAPSE after dypiridamole infusion, with a significative difference in Delta Mapse (Mapse peak-Mapse rest) between groups (0,2 mm vs 2,8 mm p = 0,004) (Figure 1B). By using a Receiver Operating Curve, the Area under the curve was 0,757, with the best cut-off value for CAD prediction at Delta Mapse= +2.5 mm (sensibility 0,667 and specificity 0,809 – p = 0.012 - Figure 1b). In particular, Delta Mapse was able to predict LM/LAD stenosis (Figure 1B AUC = 0.679 ;p = 0.019), rather than right coronary artery and circumflex artery disease, with higher predictivity than delta LV-EF (AUC = 0.577; p = 0.077). Discussion To our knowledge, this is the first study that compared the behaviour of MAPSE during dypiridamole infusion in patient with and withouth coronary artery disease. MAPSE is a well-known surrogate of longitudinal systolic function and have increased sensitivity over traditional methods of systolic performance such as LV-EF; in this context, dypiridamole induced reversible ischemia could affect prematurely MAPSE then EF or wall motion abnormalities. In our study, in patients with evidence of reversible ischemia during DSE, a blunted or no increase of MAPSE was able to predict CAD, mostly driven by LM/LAD disease, on top of other well known markers of ischemia. Incorporating this easy-to-use parameter could improve specificity of DSE and strenghten the suspect of reversibile ischemia when clear wall motion abnormalities are not found.

Multi-vessel coronary artery disease is quite a common state, which is often diagnosed by coronary angiography in patients with both stable coronary artery disease and acute coronary syndromes. Major difficulties in percutaneous coronary intervention include stent thrombosis and the need for antiplatelet therapy (aspirin and a P2Y12 inhibitor). Stent thrombosis leads to the recurrence of myocardial infarction and may occur within the first few hours after percutaneous coronary intervention. The use of dual antiplatelet therapy, especially that combined with low-molecular-weight heparin in the first days after myocardial infarction, poses a risk of bleeding, which often occurs in real clinical practice. Among P2Y12  inhibitors, ticagrelor causes bleeding somewhat more frequently than clopidogrel. A case of multi-vessel coronary artery disease is described in this paper. Coronary angiography revealed right-dominant circulation; occlusion of the proximal and medial segments of the right coronary artery, thrombolysis in myocardial infarction flow grade 0; stenosis of the left main coronary artery (50-60%), thrombolysis in myocardial infarction flow grade 2; diffuse stenosis of the medial and distal segments of the left anterior descending artery, thrombolysis in myocardial infarction flow grade 1; stenosis of the proximal segment of the left circumflex artery (> 75%), thrombolysis in myocardial infarction flow grade 1. The patient underwent percutaneous coronary intervention; the stents were implanted in the infarct-dependent right coronary artery. The clinical course was complicated by early stent thrombosis with subsequent thrombus extraction; a day later melena developed. Bleeding was stopped, the intensity of antithrombotic therapy was reduced: the combination of aspirin and ticagrelor was replaced by the combination of aspirin and clopidogrel. Six weeks after stenting of the infarct-dependent coronary artery, complete myocardial revascularization (hybrid intervention) was performed: coronary artery bypass grafting [the left internal mammary artery → the left anterior descending artery], coronary autogenous bypass grafting [the aorta → the right coronary artery and the aorta → the left circumflex artery]. The role of fractional flow reserve or instantaneous wave-free ratio-controlled complete myocardial revascularization techniques is discussed. The following algorithm for myocardial revascularization was used: percutaneous coronary intervention for the right coronary artery + coronary artery bypass grafting-3: the left internal mammary artery → the left anterior descending artery, the aorta → the left circumflex artery, the aorta → the right coronary artery.

Background: Postoperative atrial fibrillation (PoAF) is observed at a rate of 25-40% in the postoperative period after coronary artery bypass graft (CABG) surgery and can increase mortality, morbidity, and treatment costs. Inflammation and coronary artery disease (CAD) severity are important parameters to predict PoAF. Methods: Patients with right coronary artery (RCA) disease who underwent isolated CABG operation between January 1, 2017 and April 15, 2020, were included in the study retrospectively. Demographic features, preoperative total Gensini score (TGS), right coronary Gensini score (RCGS), systemic immune inflammation index (SII), and postoperative characteristics were recorded. Results: A total of 283 patients were included in the study. Those who did not develop PoAF were included in Group 1 (N = 211, median age=60 (33-82) years), and those who did were included in Group 2 (N = 72, median age=68 (42-85) years). There were no statistically significant differences between the two groups, in terms of gender, hypercholesterolemia, cerebrovascular event/trans-ischemic attack history, body mass index, diabetes mellitus, smoking, beta blocker/angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use, ejection fraction and left atrium diameters. As a result of multivariate analysis, advanced age (OR: 2.816 CI 95%: 1.687-3.498 P < .001), hypertension (OR:0.896, CI 95%: 0.578-0.965, P = .022), SII (OR: 1.548 CI 95%: 1.265-2.896, P = .003), TGS (OR: 1.235, CI 95%: 1.096-2.424, P = .012), and RCGS (OR: 2.112, CI 95%: 1.665-4.156, P < .001) values were determined as independent predictors for predicting postoperative atrial fibrillation. Conclusion: In this study, we showed that RCGS and SII values were independent predictors of PoAF after CABG operations in patients with right coronary artery disease.
