Abstract
Objectives The aim of this postmarket clinical study was to assess the safety and efficacy of the latest generation polymer-free sirolimus-eluting stents (PF-SES) in an all-comers population comparing outcomes in stable coronary artery disease (CAD) versus acute coronary syndrome (ACS) in France. Background The efficacy and safety of the first-generation PF-SES have already been demonstrated by randomized controlled trials and "all-comers" observational studies. Methods For this all-comers observational, prospective, multicenter study, 1456 patients were recruited in 22 French centers. The primary endpoint was target lesion revascularization (TLR) rate at 12 months and secondary endpoints included major adverse cardiac events (MACE) and bleeding. Results 895 patients had stable CAD and 561 had ACS. At 12 months, 2% of patients had a TLR, with similar rates between stable CAD and ACS (1.9% vs 2.2%, p = 0.7). The overall MACE rate was 5.2% with an expected higher rate in patients with ACS as compared to those with stable CAD (7.3% vs 3.9%, p = 0.007). The overall bleeding event rate was 4.5%, with similar rates in stable CAD as compared to ACS patients (3.8% vs 5.6%, p = 0.3). Dual antiplatelet therapy (DAPT) interruptions prior to the recommended duration occurred in 41.7% of patients with no increase in MACE rates as compared to patients who did not prematurely interrupt DAPT (3.9% vs 6.1%, p = 0.073). Conclusions The latest generation PF-SES is associated with low clinical event rates in these all-comers patients. There was a high rate of prematurely terminated DAPT, without any effect on MACE at 12 months. This trial is registered with NCT03809715.

Abstract
Vasospastic angina, also described as Prinzmetal angina, was first described as a variant form of angina at rest with transient ST-segment elevation; it is common and present in many clinical scenarios, including chronic and acute coronary syndromes, sudden cardiac death, arrhythmia and syncope. However, vasospastic angina remains underdiagnosed, and provocative tests are rarely performed. The gold-standard diagnostic approach uses invasive coronary angiography to induce coronary spasm using ergonovine, methylergonovine or acetylcholine as provocative stimuli. The lack of uniform protocol decreases the use and performance of these tests, accounting for vasospastic angina underestimation. This position paper from the French Coronary Atheroma and Interventional Cardiology Group (GACI) aims to review the indications for provocative tests, the testing conditions, drug protocols and positivity criteria.

Abstract
BACKGROUND The polymer-free biolimus coated stent (BioFreedom) was shown to be superior to bare metal stents in the LEADERS FREE randomized trial in high bleeding risk (HBR) patients treated with 1-month dual antiplatelet therapy (DAPT). However, there is limited outcome data with this device in an all-comers' population. METHODS We conducted a prospective single-arm study of patients undergoing percutaneous coronary intervention with the polymer-free biolimus coated stent in 25 centers in France with wide inclusion criteria including multivessel disease, complex lesions, and acute coronary syndromes. The primary endpoint was the incidence of target lesion failure (TLF), a composite of cardiac death or target-vessel myocardial infarction (MI) or clinically indicated target lesion revascularization (ci-TLR) at 1-year. The patient population was classified according to the presence (or not) of HBR criteria according to the recent ARC-HBR definition. RESULTS Between April 2019 and April 2020, 1497 patients were enrolled. TLF occurred in 101 (6.9%) patients, including cardiac death in 35 (2.4%), target vessel MI in 20 (1.4%) and ci-TLR in 65 (4.5%) of them. There were 491 HBR patients (32.8%) and 1006 non-HBR patients. The median duration of DAPT was 74 days in the HBR group versus 348 days in the non-HBR group (p < 0.0001). TLF occurred in 44 (9.2%) of the HBR group and in 57 (5.8%) of the non-HBR group (relative risk 1.62 [95% confidence interval: 1.10-2.41], p = 0015). Compared to the non-HBR group, HBR patients had higher rates of cardiac death (4.4% vs. 1.4%, p = 0.0005) and target vessel MI (2.9% vs. 0.6%, p = 0.0003), but similar rates of ci-TLR. BARC 3-5 bleeding occurred in 6.2% of the HBR group versus 1.4% of the non-HBR group (p < 0.0001). CONCLUSION In this multicenter all-comers study, HBR patients treated with a polymer-free biolimus coated stent had, compared to non-HBR patients, an increased risk of cardiac death and MI, and despite a shorter duration of DAPT, continued to have higher rates of BARC 3-5 bleeding.

Abstract
Abstract
Background
High dose statins prescription are strongly recommended in patients after acute myocardial infarction (AMI) in current guidelines.
Aim
We aimed to assess the clinical impact on major cardiovascular events (MACE) of high dose statins prescription at discharge according to the atherothrombotic risk stratification in a routine-practice population of AMI patients, and to determine the relative efficacy of currently recommended high dose statins according to risk level.
Methods
We used data from the 2005, and 2010 FAST-MI nationwide registries, including 7,839 patients with AMI (54% STEMI) admitted to cardiac intensive care units in France. Atherothrombotic risk stratification was performed using the TIMI Risk Score for Secondary Prevention (TRS-2P). Patients were defined in 3 categories: Group 1 (Low-risk; TRS-2P=0/1); Group 2 (Intermediate-risk; TRS-2P=2); and, Group 3 (High-risk; TRS-2P≥3). Baseline characteristics and the rate of MACE (defined as death, stroke or re-MI) at 5-years were analyzed according to TRS-2P categories, and the impact of high dose statins (i.e. atorvastatin 80mg/day or rosuvastatin 20mg/day) at discharge was compared using Cox multivariate analysis among the different risk groups.
Results
A total of 7,348 patients discharge alive and in whom TRS-2P was available. Prevalence of Groups 1, 2, and Group 3 was 41.5%, 25% and 33.5% respectively. Over the 5-year period, the overall risk of patients admitted for AMI decreased in Group 3 from 41% to 27% (P<0.001). Optimal medical therapy at discharge (defined by the use of dual antiplatelets therapy, statins for all; and, beta-blocker, ACE-I or ARB when appropriate) was 53% in Group 3, 67% in Group 2, and 80% in Group 1 (P<0.001). High dose statins prescription at discharge was 18.5% (Group 3), 31.3% (Group 2), and 41.3%% (Group 1). High dose statins prescription was associated with lower MACE at five-year in the overall population compared to patients with intermediate/low dose statins or without statin prescription (14.3% vs. 29.6%; Δ absolute risk= 15.3%; HR adjusted on baseline characteristics and management: 0.86, 0.76–0.97, P=0.018). The decrease in MACE at five-year was observed in all TRS-2P categories (Group 1: 8.1% vs. 10.7%, Δ= 2.6%; Group 2: 14.8% vs. 21.6%, Δ= 6.8%; Group 3: 30.8% vs. 51.6%, Δ= 20.8%). Finally, the benefits of high dose statins in low- and intermediate-risk was lower (HR=0.97; 95% CI, 0.74–1.26; P=0.81 and HR=1.06; 95% CI, 0.81–1.38; P=0.81) compared to high-risk patients (HR=0.78; 95% CI, 0.65–0.94; P=0.008).
Five-year events-free survival
Conclusions
High dose statins prescription at discharge after AMI was associated with lower MACE at five-year regardless of the atherothrombotic risk stratification, although the highest absolute reduction was found in the high risk TRS2P class.

Abstract
BACKGROUND Prolonged dual-antiplatelet therapy (DAPT) in high bleeding risk (HBR) patients undergoing percutaneous coronary intervention can be challenging. We assessed the clinical safety of bare-metal stent (BMS) implantation followed by drug-coated balloon (DCB) treatment in HBR patients for whom drug-eluting stent implantation could be problematic in maintaining low ischemic event rate without increasing hemorrhagic events. METHODS The study included patients with at least 1 de novo lesion who were either under long-term anticoagulant treatment or required semi-urgent non-coronary intervention. The strategy consisted of PRO-Kinetic Energy BMS stent (Biotronik AG) implantation followed by Pantera Lux DCB (Biotronik AG) and patients were followed for up to 12 months in 37 French centers. RESULTS Between October 2013 and April 2015, a total of 432 patients with 623 de novo lesions who were either under long-term anticoagulant treatment (n = 300) or required semi-urgent non-cardiac surgery (n = 132) were treated by BMS plus DCB. Mean patient age was 74.1 ± 9.1 years, 76.4% were men, and 38% were diabetic. The composite primary endpoint rate (defined as target-lesion failure at 12 months) was 5.6% (95% confidence interval, 3.3-7.9). Median duration for DAPT treatment was 33 days. Hemorrhagic events, as defined by the Bleeding Academic Research Consortium, occurred in 31 patients (7.2%) and definite stent thrombosis occurred in 5 patients (1.3%). CONCLUSIONS The combination of BMS plus DCB intervention is safe even with a short duration of DAPT. This strategy might be an alternative to DES implantation in HBR patients if future randomized trials support this approach.

Abstract
Objectives The French Ebiomatrix registry aimed to confirm the results of the Leaders trial in an all‐comer population in France. Background The Leaders trial showed the Biolimus‐eluting‐sent (BES) to be equivalent to the Cypher stent in terms of safety and efficacy at 1 year and superior regarding stent thrombosis after 1 year. Methods BES recipients were enrolled in 42 French centers with up to 24‐month clinical follow up. Results 2365 patients were included. Mean age: 65.7 ±11.2 years, 76.1% males, 31.8% had diabetes, 36.5% ACS (28.7% non‐ST‐elevation MI and 7.8% with ST‐elevation MI). 1.7 ± 1.0 stents/patient were implanted and procedural success was 99.5%. 12‐month follow‐up was completed in 94.3% patients and 24 months in 91.4%. MACCE rates at 12 and 24 months were 5.8% and 9% (all cause‐death 1.5% and 2.2%; stent thrombosis definite/probable 0.4% and 0.6%), respectively. MACCE were not significantly higher in diabetic patients compared with non‐diabetics but cardiac death was higher (1.6% vs. 0.6%, P = 0.01 at 1 year and 1.9% vs. 0.6, P = 0.005 at 2 years) as was stent thrombosis (0.9% vs. 0.2%, P = 0.009 and 1.2 vs. 0.3% P = 0.008). Compared with non‐ACS patients, MACCE was significantly higher in the ACS subgroup (7.5% vs. 4.8%, P = 0.001 at 1 year and 10.3% vs.8.1%, P = 0.07 at 2 years). Conclusion In this large real‐world registry, the BES with biodegradable polymer showed excellent acute and mid‐term outcomes with a 5.8% and 9% rate of MACCE at one and 2 years and a very low rate of stent thrombosis between 1 and 2 years (0.2%), thus demonstrating the replicability of the LEADERS trial in a registry population. © 2017 The Authors Catheterization and Cardiovascular Interventions Published by Wiley Periodicals, Inc.

Abstract
The signal-averaged electrocardiogram (SA-ECG) was studied in 148 patients undergoing myocardial revascularisation either by coronary bypass surgery (CBS) (64 cases) or transluminal angioplasty (PTCA) (84 cases). The investigation was performed before the procedure, at day 7 (D7) and after 3 months (D120). No difference was observed in the SA-ECG between the two groups before revascularisation. The CBS population was older, more symptomatic and had more severe lesions than the PTCA population. One hundred and thirty-nine patients were followed up until the end of the study protocol (CBS = 63; PTCA = 76). Two criteria of the SA-ECG were significantly modified after CBS: QRS duration (p < 0.05) and Under 40 (p < 0.01). No significant changes were observed after PTCA. In the patients with late potentials (LP) before revascularisation, the mean value of these criteria (Under 40 and Last 40) were significantly modified after CBS (U40 = 54.3 +/- 16 to 35.4 +/- 15; p < 0.01) (L40 = 11.9 +/- 4.7 to 26.1 +/- 24.3; p < 0.01). No changes in these criteria were observed after PTCA. The value of negativation of the criteria of LP for patients with two criteria of positivity was 71.1% after CBS compared with 25% after PTCA (not significant). These observations support the hypothesis of a favourable modification of the arrhythmogenic substrate after myocardial revascularisation, especially by CBS.

Abstract
Exercise thallium-201 single photon emission computed tomography images were compared prospectively with 4-hour redistribution images, with 4-hour reinjection images, and with images obtained at rest on a separate day in 37 patients with documented coronary artery disease. Exercise images were abnormal in 35 patients (95%). On the basis of an improvement in thallium-201 distribution between exercise and nonexercise images, overall sensitivity for the detection of coronary artery stenosis was significantly higher with reinjection at 4 hours (p < 0.05) or with a rest injection on a separate day (p < 0.05) than with redistribution imaging (84%, 83%, and 70%, respectively). Reinjection and rest injection were positive more frequently in patients with a wall-motion abnormality (76% and 80%, respectively, vs 64% at redistribution; p < 0.05 for both) or with > 90% stenosis (77% and 76%, respectively, vs 58% at redistribution; p < 0.05 for both). Among the 11 patients who had no evidence of redistribution at 4 hours, five (45%) demonstrated ischemia with reinjection and five demonstrated ischemia in the separate rest study; a total of seven patients showed improvement either at reinjection or rest. Among these 86% had a wall-motion abnormality associated with stenosis of > 90%, whereas in the other 30 patients these two conditions were observed concomitantly in only 43%. This study demonstrates that the thallium-201 4-hour postexercise reinjection technique is as sensitive as the 2-day rest/exercise method for the detection of coronary artery stenosis and provides additional information when a severe stenosis is associated with a wall-motion abnormality.

Abstract
The authors report the case of a 35 year old man with no known previous cardiac disease. One month after a tic bite causing diffuse abdominal erythema, he was admitted to hospital with fever, breathlessness and bradycardia. The electrocardiogramme showed first degree atrioventricular block with a sinoatrial block (SA = 200 ms, AH = 240 ms). Echocardiography eliminated the diagnosis of pericardial effusion. Thallium 201 myocardial scintigraphy was pathological and showed irregular global uptake suggesting cardiomyopathy. Gallium 67 scintigraphy showed increased uptake in the left ventricle. The evolution was uncomplicated with normalisation of clinical, ECG and radiological changes. Cardiac catheterisation and angiography eliminated ischaemic and primary cardiomyopathy. Control radionuclide investigations were normal at one month: there was no persistent abnormal Gallium uptake. The diagnosis of Lyme's syndrome was confirmed by positive serology with successive titres of 1/1024 and 1/2048 (significant at titres over 1/256). This unusual case illustrates: the risk of myocardial disease in Lyme's syndrome; the diagnostic value of Gallium 67 scintigraphy in acute myocarditis: Gallium seems to fix specifically on inflamed tissues, so distinguishing myocarditis from primary cardiomyopathies.
