Background: Diabetes mellitus (DM) is one of the major risk factors contributing to Acute Coronary Syndromes (ACS) and is associated with an increased risk of adverse clinical outcomes following percutaneous coronary intervention (PCI), even when the second generation of drug-eluting stents (DES) is used. In order to overcome the disadvantages of permanent caging of a vessel with metallic DES, bioresorbable scaffold (BRS) technology has been recently developed. However, the prognosis of patients with DM and ACS treated with PCI via subsequent implantation of Magmaris (Biotronik, Berlin, Germany)—a novel magnesium-bioresorbable scaffold—is poorly investigated. Methods: A total of 193 consecutive subjects with non-ST elevation acute coronary syndrome (NSTE-ACS) who, from October 2016 to March 2020, received one or more Magmaris scaffolds were enrolled in this study. The diabetic group was compared with non-diabetic subjects. Results: There were no significant differences in the occurrence of primary endpoints (cardiovascular death, myocardial infarction, and in-stent thrombosis) and principal secondary endpoints (target-lesion failure, scaffold restenosis, death from any reason, and other cardiovascular events) between the two compared groups in a 1-year follow-up period. Conclusions: The early 1-year-outcome of magnesium bioresorbable scaffold (Magmaris) seems to be favorable and suggests that this novel BRS is safe and effective in subjects with NSTE-ACS and co-existing DM.

Introduction The benefits of short versus long-term dual antiplatelet therapy (DAPT) based on the third generation P2Y12 antagonists prasugrel or ticagrelor, in patients with acute coronary syndromes treated with percutaneous coronary intervention remain to be clearly defined due to current evidences limited to patients treated with clopidogrel. Methods All acute coronary syndrome patients from the REgistry of New Antiplatelets in patients with Myocardial Infarction (RENAMI) undergoing percutaneous coronary intervention and treated with aspirin, prasugrel or ticagrelor were stratified according to DAPT duration, that is, shorter than 12 months (D1 group), 12 months (D2 group) and longer than 12 months (D3 group). The three groups were compared before and after propensity score matching. Net adverse clinical events (NACEs), defined as a combination of major adverse cardiac events (MACEs) and major bleedings (including therefore all cause death, myocardial infarction and Bleeding Academic Research Consortium (BARC) 3–5 bleeding), were the primary end points, MACEs (a composite of all cause death and myocardial infarction) the secondary one. Single components of NACEs were co-secondary end points, along with BARC 2–5 bleeding, cardiovascular death and stent thrombosis. Results A total of 4424 patients from the RENAMI registry with available data on DAPT duration were included in the model. After propensity score matching, 628 patients from each group were selected. After 20 months of follow up, DAPT for 12 months and DAPT for longer than 12 months significantly reduced the risk of NACE (D1 11.6% vs. D2 6.7% vs. D3 7.2%, p = 0.003) and MACE (10% vs. 6.2% vs. 2.4%, p < 0.001) compared with DAPT for less than 12 months. These differences were driven by a reduced risk of all cause death (7.8% vs. 1.3% vs. 1.6%, p < 0.001), cardiovascular death (5.1% vs. 1.0% vs. 1.2%, p < 0.0001) and recurrent myocardial infarction (8.3% vs. 5.2% vs. 3.5%, p = 0.002). NACEs were lower with longer DAPT despite a higher risk of BARC 2–5 bleedings (4.6% vs. 5.7% vs. 6.2%, p = 0.04) and a trend towards a higher risk of BARC 3–5 bleedings (2.4% vs. 3.3% vs. 3.9%, p = 0.06). These results were not consistent for female patients and those older than 75 years old, due to an increased risk of bleedings which exceeded the reduction in myocardial infarction. Conclusion In unselected real world acute coronary syndrome patients treated with percutaneous coronary intervention, DAPT with prasugrel or ticagrelor prolonged beyond 12 months markedly reduces fatal and non-fatal ischaemic events, offsetting the increased risk deriving from the higher bleeding risk. On the contrary, patients >75 years old and female ones showed a less favourable risk–benefit ratio for longer DAPT due to excess of bleedings.

Abstract This study aimed to compare the strut coverage between Orsiro ultrathin struts biodegradable polymer sirolimus-eluting stents (O-SES) and Xience thin struts durable polymer everolimus-eluting stents (X-EES) in acute coronary syndrome (ACS) patients using optical coherence tomography (OCT). In BIOSTEMI trial, O-SESs were superior to X-EESs with respect to target lesion failure (TLF) in ACS patients. However, there were few reports comparing intravascular imaging between the two stents in ACS. Between August 2016 and February 2020, 50 lesions from 50 ACS patients who underwent OCT-guided percutaneous coronary intervention (PCI) were enrolled. We compared mid-term vascular healing using OCT between O-SESs and X-EESs at 8-month after stenting. The protocol was approved by the Osaka Rosai Hospiral ethics committee. Among 50 lesions, the X-EES group consisted of 25 lesions and the O-SES of 25 lesions. The percentage of covered strut, the percentage of malapposed strut and mean neointimal thickness at 8-month were evaluated. In the 8-month OCT analysis, the proportion of covered strut was significantly higher in the O-SES group than in in the X-EES group (97.3% vs. 86.0%; p = 0.001). On the other hand, there were no significant differences in the frequency of malapposed strut (0.4% vs 1.0%, p = 0.238). The O-SES group had the tendency of thinner neointima compared to the X-EES group (60µm vs 76µm, p = 0.089). Compared to X-EESs, O-SESs showed better mid-term vascular healing and tended to have thinner neointima in ACS patients. Ultra-thin strut may play a key role in better vascular healing.

Background: Despite the developments in percutaneous coronary interventions (PCI), women are still more likely than men to have unfavorable outcomes after PCI performed in Acute Coronary Syndrome (ACS). The mechanisms of this phenomena are not fully understood. Potential benefits of bioresorbable scaffolds (BRS) may be particularly expressed in the female population. Nevertheless, the data available currently are inconsistent and limited. This study evaluated the gender-related differences in the short-term clinical outcomes in ACS patients treated with implantation of two generations of BRS (first generation, Absorb; second generation, Magmaris). Methods: The study was divided into two arms. To the first one, we qualified 160 patients with ACS treated with PCI who received 210 Absorb scaffolds. The second arm was composed of 193 patients with ACS who underwent PCI with Magmaris implantation. Results: There were no significant sex-related differences in primary endpoints (cardiovascular-death, myocardial infarction, in-stent thrombosis) or principal secondary endpoints (of target-lesion failure, scaffold restenosis, death from any reason, other cardiovascular events) in either generation of BRS in a 1-year follow-up. Conclusions: Both genders tended to have a similar outcome in routine clinical practice following BRS implantation due to ACS. The magnesium bioresorbable scaffold (Magmaris) early outcome seemed to be more favorable in comparison to the Absorb scaffold.

Over the last decades, inflammation proved to play a pivotal role in atherosclerotic plaque formation, progression and destabilization. Several studies showed that the patients presenting with acute coronary syndrome are at increased risk of adverse cardiovascular events at both short- and long-term follow-up. Results from different clinical trials highlighted that a residual inflammatory risk exist and targeting inflammation is a successful strategy in selected cases associated to an increased inflammatory burden. Recently, the optimization of intracoronary and multimodality imaging allowed to also assess the entity of local inflammation, thus encouraging the individuation of plaque characteristics that portend a higher risk of future cardiovascular events. In this short review, we aim to highlight the role of systemic and local inflammation in acute coronary syndromes, to provide a summarized overview of the possible medical strategies applicable in selected cases and to underline the diagnostic and prognostic potential of multimodality imaging.

Background. COVID-19 increases the risk of developing thromboembolic complications, including acute myocardial infarction, in the acute period of the disease. The long-term consequences of COVID-19 are poorly understood. At the same time, the available data on an increased risk of acute coronary syndrome after infectious diseases allow us to make an assumption about a similar risk in COVID-19. The aim of the study was to study the anamnestic and laboratory diagnostic data in patients with acute coronary syndrome after COVID-19. Methods. The study included 185 patients with acute coronary syndrome who were admitted to the State Clinical Hospital No. 13 in Moscow in the period from May to December 2020. 2 groups were identified: group 1 109 patients with ACS who had previously suffered COVID-19, group 2 76 patients with ACS without COVID-19 in the past. The patients were collected anamnesis, including: the fact of smoking and alcohol consumption, heredity, previous diseases, including diabetes mellitus, acute myocardial infarction, previously performed PCI. Information about the COVID-19 infection has been collected (the duration of the disease, the course of the disease). A clinical and laboratory examination was conducted, including the determination of body mass index (BMI), examination for antibodies to COVID-19, determination of the lipid profile level (total cholesterol, LDL, HDL, triglycerides), blood glucose level, C-RB. The analysis was performed on automatic biochemical analyzers Hitachi-902, 912 (Roche Diagnostics, Japan). All patients underwent coronary angiography. Results. In patients with ACS with previously transferred COVID-19, the development of the disease occurred at a younger age compared to patients without transferred COVID-19. Among the patients with COVID-19, body weight was significantly lower, there were fewer smokers, concomitant type 2 diabetes mellitus and transferred ONMC were less common. In laboratory parameters, lower triglyceride levels were observed in patients with ACS with COVID-19 compared with those of patients without COVID-19. In the laboratory parameters of blood clotting in patients with ACS with COVID-19, higher APTT, thrombin time, fibrinogen level, D-dimer were noted. The indicated laboratory parameters in the groups had statistically significant differences. In ACS patients with a previous COVID-19, compared with patients without COVID-19, the lesion of 2 or more coronary vessels was more common in the anamnesis. Conclusion. According to the results of our study, it was revealed that multivessel coronary artery damage in patients after COVID-19 in comparison with patients without COVID-19 develops significantly more often, while these patients are significantly less likely to have DM and previously suffered ONMC, the level of TG is significantly lower.

Background Long‐term use of antiplatelet agents after acute coronary syndrome in diabetic patients is not well known. Here, we describe antiplatelet use and outcomes in such patients enrolled in the EPICOR Asia (Long‐Term Follow‐up of Antithrombotic Management Patterns in Acute Coronary Syndrome Patients in Asia) registry. Methods and Results EPICOR Asia is a prospective, observational study of 12 922 patients with acute coronary syndrome surviving to discharge, from 8 countries/regions in Asia. The present analysis included 3162 patients with diabetes mellitus (DM) and 9602 patients without DM. The impact of DM on use of antiplatelet agents and events (composite of death, myocardial infarction, and stroke, with or without any revascularization; individual components, and bleeding) was evaluated. Significant baseline differences were seen between patients with DM and patients without DM for age, sex, body mass index, cardiovascular history, angiographic findings, and use of percutaneous coronary intervention. At discharge, ≈90% of patients in each group received dual antiplatelet therapy. At 2‐year follow‐up, more patients with DM tended to still receive dual antiplatelet therapy (60% versus 56%). DM was associated with increased risk from ischemic but not major bleeding events. Independent predictors of the composite end point of death, myocardial infarction, and stroke in patients with DM were age ≥65 years and use of diuretics at discharge. Conclusions Antiplatelet agent use is broadly comparable in patients with DM and patients without DM, although patients with DM are more likely to be on dual antiplatelet therapy at 2 years. Patients with DM are at increased risk of ischemic events, suggesting an unmet need for improved antithrombotic treatment.
