Myocardial (muscle) bridges are a common congenital anomaly of coronary arteries which is characterized by running of a coronary artery segment under the myocardial layer. According to literary data, the most frequent localization of myocardial bridges is observed in the middle segment of the anterior interventricular branch. In the majority of cases, the presence of a muscular bridge is not accompanied by clinical manifestations, and patients have a favorable long-term prognosis.Under certain circumstances, the course of the intramural course of the coronary artery may be accompanied by development of acute coronary syndrome, a sudden cardiac death. The main method of the diagnosis is coronary angiography. The article presents brief data on the prevalence, clinical picture, diagnosis, treatment of patients with myocardial bridges. Also, it describes a clinical case of a patient havinga myocardial bridge in the middle segment of the anterior interventricular branch with characteristic clinical symptoms confirmed by tool research methods.

Artery Segment

Coronary artery aneurysm (CAA) is described as a localized dilatation of a coronary artery segment by more than 1.5-fold compared with the adjacent normal segments. The incidence of CAA varies from 0.3 to 5.3% with atherosclerosis, Takayasu arteritis, congenital disorders, Kawasaki disease, and percutaneous coronary intervention (PCI) being the common etiologic factors. Owing to its varying presentation and absence of robust treatment guidelines, management of CAA is a challenge. Management of every patient must be tailored according to the presentation and expertise of the cardiac team available. Here, we present case reports of two patients with CAA who presented with acute coronary syndrome. As a result of unstable presentation, both patients underwent immediate intervention (CABG and PCI respectively) with successful revascularization having no complication and mortality.

Abstract Objectives To evaluate computed tomography fractional flow reserve (FFRCT) values in distal parts of the coronaries in an asymptomatic cohort of marathon runners without any coronary stenosis for potentially false-positive values. Methods Ninety-eight asymptomatic male marathon runners (age 53 ± 7 years) were enrolled in a prospective monocentric study and underwent coronary computed tomography angiography (CCTA). CCTA data were analyzed for visual coronary artery stenosis. FFRCT was evaluated in 59 participants without coronary artery stenosis in proximal, mid, and distal coronary sections using an on-site software prototype. Results In participants without coronary artery stenosis, abnormal FFRCT values ≤ 0.8 in distal segments were found in 22 participants (37%); in 19 participants in the LAD; in 5 participants in the LCX; and in 4 participants in the RCA. Vessel diameters in participants with FFRCT values > 0.80 compared to ≤ 0.80 were 1.6 ± 0.3 mm versus 1.5 ± 0.3 mm for distal LAD (p = 0.025), 1.8 ± 0.3 mm versus 1.6 ± 0.5 mm for distal LCX (p = 0.183), and 2.0 ± 0.4 mm versus 1.5 ± 0.2 mm for distal RCA (p < 0.001). Conclusions Abnormal FFRCT values of ≤ 0.8 frequently occurred in distal coronary segments in subjects without any anatomical coronary artery stenosis. This effect is only to some degree explainable by small distal vessel diameters. Therefore, the validity of hemodynamic relevance evaluation using FFRCT in distal coronary artery segment stenosis is reduced. Key Points • Abnormal FFRCT values (≤ 0.8) occurred in over a third of the subjects in the distal LAD despite the absence of coronary artery stenosis.. • Therefore, the validity of hemodynamic relevance evaluation in distal coronary artery segment stenosis is reduced. • Decision-making based on abnormal FFRCT values in distal vessel sections should be performed with caution and only in combination with visual assessment of the grade of stenosis..

Abstract Background Anemia is a frequent comorbidity in patients with coronary artery disease (CAD). Besides a complemental effect on myocardial oxygen undersupply of CAD and anemia, available data suggests that it may independently impact the prognosis in CAD patients. We aimed to determine the association of anemia with long-term survival in a longitudinal registry of patients undergoing conventional coronary angiography. Methods The present analysis is based on the ECAD registry of patients undergoing conventional coronary angiography at the Department of Cardiology and Vascular Medicine at the University Clinic Essen between 2004 and 2019. For this analysis, we excluded all patients with missing hemoglobin levels at baseline admission or missing follow-up information. Anemia was defined as a hemoglobin level of &lt;13.0g/dl for male and &lt;12.0g/dl for female patients according to the world health organization's definition. Cox regression analysis was used to determine the association of anemia with morality, stratifying by clinical presentation of patients. Hazard ratio and 95% confidence interval are depicted for presence vs. absence of anemia. Results Overall, data from 28,917 patient admissions (mean age: 65.3±13.2 years, 69% male) were included in our analysis (22,570 patients without and 6,347 patients with anemia). Prevalence of anemia increased by age group (age &lt;50 years: 16.0%, age ≥80 years: 27.7%). During a mean follow-up of 3.2±3.4 years, 4,792 deaths of any cause occurred (16.6%). In patients with anemia, mortality was relevantly higher as compared to patients without anemia (13.4% vs. 28.0% for patients without and with anemia, respectively, p&lt;0.0001, figure 1). In univariate regression analysis, anemia was associated with 2.4-fold increased mortality risk (2.27–2.55, p&lt;0.0001). Effect sizes remained stable upon adjustment for traditional risk factors (2.38 [2.18–2.61], p&lt;0.0001). Mortality risk accountable to anemia was significantly higher for patients receiving coronary interventions (2.62 [2.35–2.92], p&lt;0.0001) as compared to purely diagnostic coronary angiography examinations (2.31 [2.15–2.47], p&lt;0.0001). Likewise, survival probability was slightly worse for patients with anemia in acute coronary syndrome (2.70 [2.29–3.12], p&lt;0.0001) compared to chronic coronary syndrome (2.60 [2.17–3.12], p&lt;0.0001). Interestingly, within the ACS entity, association of anemia with mortality was relevantly lower in STEMI patients (1.64 [1.10–2.44], p=0.014) as compared to NSTEMI and IAP (NSTEMI: 2.68 [2.09–3.44], p&lt;0.0001; IAP: 2.67 [2.06–3.47], p&lt;0.0001). Conclusion In this large registry of patients undergoing conventional coronary angiography, anemia was a frequent comorbidity. Anemia relevantly influences log-term survival, especially in patients receiving percutaneous coronary interventions. Our results confirm the important role of anemia for prognosis in patients with coronary artery disease, demonstrating the need for specific treatment options. Figure 1.

Background: Long term outcomes of culprit multi-vessel and left main patients who presented with Non-ST Elevation Acute Coronary Syndrome (NSTE-ACS) and underwent either coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) are not well defined. Randomized trials comparing the two modalities constituted mainly of patients with stable coronary artery disease (SCAD). We performed a meta-analysis of studies that compared the long term outcomes of CABG vs. PCI in NSTE-ACS. Methods: Medline, EmCare, CINAHL, Cochrane databases were queried for relevant articles. Studies that included patients with SCAD and ST-elevation myocardial infarction were excluded. Our primary outcome was major adverse cardiac events (MACE) at 3-5 years, defined as a composite of all-cause mortality, stroke, re-infarction and repeat revascularization. The secondary outcome was re-infarction at 3 to 5 years. We used the Paule-Mandel method with Hartung-Knapp-Sidik-Jonkman adjustment to estimate risk ratio (RR) with 95% confidence interval (CI). Heterogeneity was assessed using Higgin’s I 2 statistics. All statistical analysis was carried out using R version 3.6.2 Results: Four observational studies met our inclusion criteria with a total number of 6695 patients. At 3 to 5 years, the PCI group was associated with a higher risk of MACE as compared to CABG, (RR): 1.52, 95% CI: 1.28 to 1.81, I 2 =0% (PANEL A). The PCI group also had a higher risk of re-infarctions during the period of follow up, RR: 1.88, 95% CI 1.49 to 2.38, I 2 =0% (PANEL B). Conclusion: In this meta-analysis, CABG was associated with a lower risk of MACE and re-infarctions as compared to PCI during 3 to 5 years follow up period.

Spontaneous coronary artery dissection (SCAD) is a rare but increasingly recognised cause of acute coronary syndrome. While numerous risk factors are associated with SCAD, one potential cause is coronary artery vasospasm. The use of cabergoline—an ergot derivative and dopamine agonist that may induce vasospasm—has been associated with SCAD in one other case report worldwide. Here, we describe SCAD in a 37-year-old woman on long-term cabergoline therapy with no other cardiac risk factors. Cabergoline-induced SCAD should be considered in patients presenting with an acute coronary syndrome who are treated with this medication.

Justification. The results of endovascular revascularization are largely determined by the type of stents used. The use of baremetal coronary stents significantly worsens the long-term results of endovascular treatment of coronary artery disease. Given the widespread use of bare-metal coronary stents in the Russian Federation for the treatment of coronary artery disease and acute coronary syndrome, in particular, the issue of the impact of the above-mentioned endovascular interventions on the long-term results of coronary artery bypass grafting (CABG) performed after endovascular revascularization of the clinically related artery in patients with acute coronary syndrome and multivessel lesions does not lose relevance.Aim. To compare the long-term results of the staged strategies of revascularization of the coronary bed: CABG performed after stenting the clinically related artery with third-generation biodegradable polymer-based sirolimus-eluting stents for acute coronary syndrome and CABG performed after stenting the clinically related artery with bare-metal coronary stents for acute coronary syndrome.Material and Methods. The analysis used the data of two-year follow-up of patients who underwent two-stage revascularization: at the first stage, patients received stenting of the clinically related artery for acute coronary syndrome and, at the second stage, they received coronary artery bypass grafting no later than 90 days from the date of stenting. The study included 218 patients with multivessel lesions of the coronary bed, admitted with clinical manifestation of acute coronary syndrome. The long-term follow-up period was 24 months. The following end points were analyzed: cardiovascular mortality, myocardial infarction, re-revascularization, and combined MACCE end point (cardiovascular mortality, myocardial infarction, acute cerebrovascular accident, and re-revascularization). The observation was carried out at the hospital stage and, then, on an outpatient basis once every three months.Results. There were no significant differences between the groups. The frequency of repeated revascularization, including repeated revascularization of the stented artery, and recurrence of angina were significantly higher in the group with baremetal coronary stents. There were no significant differences between the groups in regard to cardiovascular mortality, nonfatal myocardial infarction and acute cerebrovascular accidents. The frequency of MACCE events was significantly higher in the group of bare-metal coronary stents, mainly due to the frequency of repeated revascularizations.Conclusion. Coronary artery bypass grafting performed in the early period after stenting of the clinically related artery using bare-metal coronary stents in patients with acute coronary syndrome and multivessel lesions was associated with a significantly larger number of repeated coronary revascularizations and higher rate of recurrent angina compared to a similar strategy, but with the use of modern third-generation biodegradable polymer-based sirolimus-eluting stents.

Background: Little is known about the effect of gender and race on outcomes in patients after revascularization of proximal coronary lesions (PCL). We investigated their effect on outcomes using the NHLBI Dynamic Registry. Methods: Of the 9962 patients receiving PCI, 3918 (39%) were treated for disease in a proximal coronary artery segment. Left main and PCI for graft lesions were excluded. Primary outcomes were death/MI or need for repeat revascularization at 1 year after the index procedure. Results: 80% of the patients were white (n=3144), 11% black (n=469), 63% male (n=2461), and 37% female (n=1457). Patients with PCL had lower rates of HTN, prior MI, but where older and had more concomitant medical disease. Compared to non-proximal lesions, patients with PCL had higher rate of death (5.4% vs. 4%, p=0.001) and repeat revascularization (16.3% vs. 14.3%, p=0.01). The effect of gender and race were then included in the multivariate model for predicting risk in patients with PCL (Table 1 ). Race did not modify the risk associated with PCL but females had a 32% greater relative risk (p=0.002) of repeat revascularization when compared to men. Conclusions: Treatment of proximal coronary lesions is associated with a more adverse outcomes compared to non-proximal coronary lesions. In this high-risk population, female gender is an independent predictor for the need for repeat revascularization.

Abstract Endothelial dysfunction is involved in the development of atherosclerosis, which precedes asymptomatic structural vascular alterations as well as clinical manifestations of cardiovascular disease (CVD). Endothelial function can be assessed non-invasively using the flow-mediated dilation (FMD) technique. Flow-mediated dilation represents an endothelium-dependent, largely nitric oxide (NO)-mediated dilatation of conduit arteries in response to an imposed increase in blood flow and shear stress. Flow-mediated dilation is affected by cardiovascular (CV) risk factors, relates to coronary artery endothelial function, and independently predicts CVD outcome. Accordingly, FMD is a tool for examining the pathophysiology of CVD and possibly identifying subjects at increased risk for future CV events. Moreover, it has merit in examining the acute and long-term impact of physiological and pharmacological interventions in humans. Despite concerns about its reproducibility, the available evidence shows that highly reliable FMD measurements can be achieved when specialized laboratories follow standardized protocols. For this purpose, updated expert consensus guidelines for the performance of FMD are presented, which are based on critical appraisal of novel technical approaches, development of analysis software, and studies exploring the physiological principles underlying the technique. Uniformity in FMD performance will (i) improve comparability between studies, (ii) contribute to construction of reference values, and (iii) offer an easy accessible and early marker of atherosclerosis that could complement clinical symptoms of structural arterial disease and facilitate early diagnosis and prediction of CVD outcomes.
