Abstract
BACKGROUND In patients at high bleeding risk (HBR), the LEADERS FREE (LF) trial established the safety and efficacy of a polymer-free drug coated (Biolimus-A9) stainless steel stent (SS-DCS) with 30 days of dual antiplatelet treatment (DAPT). In LEADERS FREE III, we studied a new cobalt-chromium thin-strut stent (CoCr-DCS) in HBR patients. METHODS The CoCr-DCS shares all of the design features of the SS-DCS but has a CoCr stent platform with strut thickness of 84-88 μm. The primary safety endpoint was a composite of cardiac death, myocardial infarction (MI), and definite/probable stent thrombosis. The primary efficacy endpoint was clinically indicated target lesion revascularization. Outcomes were compared to those of LF (non-inferiority to SS-DCS for safety and superiority to SS-BMS for efficacy). Additional propensity-matched comparisons were performed to account for baseline differences. RESULTS We recruited 401 HBR patients using identical criteria to the LF trial. At 1 year, the primary safety endpoint was reached by 31/401 (8.0%) of patients treated with the CoCr-DCS versus 35/401 (8.9%) for the propensity-matched cohort (HR: 0.89, [0.55-1.44], p < 0.001 for non-inferiority, 0.62 for superiority). The efficacy endpoint was reached by 16/401 (4.2%) of CoCr-DCS patients versus 41/401 (10.6%) in the propensity-matched cohort (HR: 0.4 [0.2:0.7]) (p = 0.007 for superiority). There was no statistical difference between CoCr-DCS and SS-DCS in terms of efficacy (HR: 1.46 [0.68-3.15], p = 0.33). CONCLUSIONS The new thin-strut CoCr-DCS proved non-inferior to the SS-DCS for safety, and superior to the BMS for efficacy in HBR patients treated with 30 days of DAPT.

Abstract
Abstract
Aim
Radio-contrast agents are widely used in coronary, peripheral and structural interventions. Use of these iodine-containing agents can be associated with contrast-induced acute kidney injury (CI-AKI) that can cause substantial morbidity and mortality. The RenalGuard system induces a forced diuresis with a matched hydration and has been shown beneficial in patients requiring coronary angiogram and PCI.
Methods
STRENGTH is a prospective, randomised (1:1), open-labeled, parallel-group, multicenter (10 centers in Germany and France) study where patients at high risk of CI-AKI were randomly assigned to RenalGuard® therapy or conventional strategy including preventive hydration before complex percutaneous cardiovascular intervention (PCI, peripheral and structural). In the RenalGuard arm, matched fluid replacement was started 60 minutes pre-procedure and maintained for up to 4 hours afterwards. Patients were given an initial i.v. bolus of up to 250 ml of normal saline over 30 minutes and then an i.v. bolus of furosemide (0.5 mg/kg). To be enrolled, patients had to have moderate to severe renal failure (defined as 15≤eGFR≤40 mL/min/m2) and a high-volume contrast requiring cardiovascular procedure (estimated contrast volume>3 times eGFR value). The main exclusion criterion was administration of iodine contrast media within 5 days before index procedure. The primary endpoint was CI-AKI defined as an increase in sCr ≥0.3 mg/dL or an increase of 25% of basal value or requiring dialysis within 5 days after procedure. The primary analysis for efficacy is performed in a modified intention-to-treat basis. The trial was designed and monitored by an independent CRO (Cardiovascular European Research Center, CERC, Massy, France).
Results
A total of 259 patients aged 79.1±8.8 yrs were included in the study. Among them, 129 were assigned to RenalGuard therapy and 130 to preventive saline hydration. Their mean baseline eGFR was 32 (25; 37) vs. 33 (25; 39) mL/min/m2, respectively (p=0.88). Total fluid intake volume within 24hrs before the procedure was 2383±1146 vs. 1386±842mL, respectively (p<0.0001). Procedure type was complex PCI (48%), TAVI (25%), peripheral intervention (18%), other structural intervention (9%) with no difference between groups (p=0.56). The total amount of contrast used for the procedure was 116.3±68.2mL in the RenalGuard arm vs. 104.1±56.7 mL in the conventional arm (p=0.26). A staged procedure was performed in 24 patients, including 16 in the RenalGuard and 8 in the control arm with a mean interval from the first intervention of 43±29 days and 24±19 days, respectively. For this second procedure, the total amount of contrast was 80±59 vs. 87±73mL.
Conclusion
The primary and secondary endpoints of the Study To evaluate the use of RENalGuard to proTect patients at High risk of CI-AKI comparing RenalGuard therapy to conventional hydration in 259 patients requiring complex percutaneous cardiovascular intervention will be presented.

Abstract
BACKGROUND The effectiveness of bivalirudin in patients undergoing percutaneous coronary intervention for acute myocardial infarction has been tested in clinical trials, but its use in a real-world scenario has never been reported. METHODS From the total number of patients enrolled in the EUROVISION registry, 678 subjects affected by ST-elevation myocardial infarction were selected and included in the analysis. Posology and usage patterns of bivalirudin, as evaluated by dose and time of drug bolus and infusion administered, were evaluated. The 30-day outcome has been assessed by efficacy and safety endpoints. RESULTS All patients received an initial intravenous bolus of bivalirudin (0.70±0.25 mg/kg) followed by an infusion (1.58±0.47 mg/kg/h; duration: 60 [30, 107] min) in 99.3% of cases. An additional bolus (0.49±0.06 mg/kg) was administered in 9.3% of patients. Bivalirudin infusion was prolonged after procedure in 62.2%. Death occurred in 2.1% of patients, non-fatal myocardial reinfarction in 0.3%, unplanned revascularization in 0.6% and non-fatal stroke in 0.4%. Acute stent thrombosis was not observed. Major bleeding occurred in 1.5% of patients. CONCLUSIONS Bivalirudin usage in the setting of primary PCI provided excellent results in terms of 30-day outcome even in a real-world population.

Abstract
Recently, Japanese authors have described a new clinical entity associating apical akidyskinesia and basal hyperkinesias without significant coronary artery disease under the name of the tako-tsubo syndrome. This syndrome is usually observed in elderly women and the clinical presentation is usually that of an acute coronary syndrome. The authors report 10 cases of patients investigated between June 2003 and August 2004. All patients were women with an average age of 66 +/- 15 years. Seven patients had chest pain on admission with, in three cases, signs of cardiac failure. In 8 patients, a causal factor was identified: emotional stress in 7 cases and anaphylactic shock in one case. All patients underwent coronary angiography and ventriculography which showed typical changes in left ventricular contractility without significant coronary disease. The peak CPK and troponin values were 222 +/- 115 UI/l and 3.32 +/- 1.50 microg/l, respectively. One patient died in cardiogenic shock. In the other cases, normalisation of wall motion was observed in the month following the onset of symptoms. One patient developed 3rd degree atrioventricular block and required implantation of a pacemaker. This clinical entity must be taken into consideration in elderly women with acute coronary syndromes.

Abstract
PURPOSE To define a subgroup of patients at increased risk of renal artery stenosis (RAS) in a population of patients undergoing cardiac catheterization. MATERIALS AND METHODS A total of 467 patients (mean age of 64 Years +/-11) underwent cardiac catheterization and aortography Results were evaluated to detect correlations between the presence or absence of RAS and clinical and biological parameters. RESULTS A total of 42 (9%) patients had a renal artery stenosis. Univariate analysis defined parameters correlated with the presence of RAS: systolic blood pressure (p=0.03), pulse pressure (p=0.005), age (p<0.0001), creatinine clearance (p<0.0001), 2-vessel (p=0.028) and 3-vessel (p=0.037) coronary artery diseases. Multivariate analysis showed that the presence of RAS correlated to creatinine clearance (p=0.02) and 2-vessel coronary artery disease. A creatinine clearance between 30 and 60 ml/min and multi-vessel coronary artery disease defined a subgroup at increased risk of RAS with sensitivity, specificity, positive and negative predictive values of: 47.6, 90.1, 32.3 and 94.6%. The prevalence of renal artery stenosis was 5.2% when both parameters were absent. CONCLUSION Patients with mild renal insufficiency and multi-vessel coronary artery disease defined a subgroup of patients at increased risk of RAS (32.5%) that may benefit from abdominal aortography performed at the time of cardiac catheterization.

Abstract
BACKGROUND Preliminary trials of direct coronary stenting have demonstrated the benefits of this approach. It lowers procedural cost, time, and radiation exposure compared with predilatation. Nevertheless, the long-term outcome after direct stenting remains less well known. METHODS Between January and September 1999, 338 patients were randomly assigned to either direct stent implantation (DS+, n = 173) or standard stent implantation with balloon predilatation (DS-, n = 165). Clinical follow-up was performed. RESULTS Baseline characteristics were similar in the 2 groups. Procedural success was achieved in 98.3% of patients assigned to DS+ and 97.5% of patients assigned to DS- (not significant). Clinical follow-up was obtained in 99% of patients (mean 16.4 +/- 4.6 months). Major adverse cardiac events--defined as whichever of the following occurred first; cardiac death, myocardial infarction, unstable angina, new revascularization--were observed at a higher rate in the DS+ group than in the DS-, but this difference was not significant (11.3% vs 18.2%, P = not significant). The difference in target lesion revascularization rate in the DS+ group (7%) and DS- group (5.2%) was also not significant. Multivariate analysis showed that direct stenting had no influence on long-term major adverse cardiac events rate. Independent relationships were found between long-term major adverse cardiac events rate and final minimal lumen diameter <2.48 mm (relative risk [RR] 0.449, CI 0.239-0.845, P =.013), prior myocardial infarction (RR 2.028, CI 1.114-3.69, P =.02), and hypertension (RR 1.859, CI 1.022-3.383, P =.042). CONCLUSION The main finding that emerges from this randomized study is that the influence of direct stenting on long-term need for new target lesion revascularization does not differ from that of stenting with balloon predilatation.

Abstract
BACKGROUND Stenting has been demonstrated to be superior to balloon angioplasty in de novo focal lesions located in large native vessels. However, in small vessels, the benefit of stenting remains questionable. METHODS AND RESULTS A total of 381 symptomatic patients with de novo focal lesion located on a small coronary segment vessel (<3 mm) were randomly assigned to either stent implantation (192 patients; 197 lesions) or standard balloon angioplasty (189 patients; 198 lesions). The primary end point was the angiographic restenosis rate at 6 months, as determined by quantitative coronary angiography. On intention-to-treat analysis, angiographic success rate and major adverse cardiac events were comparable: 97.9% and 4.6% versus 93.9% and 5.8% in the stent group and the balloon group, respectively. After the procedure, a larger acute gain was achieved with stent placement (1.35+/-0.45 versus 0.94+/-0.47 mm, P=0.0001), resulting in a larger minimal lumen diameter (2.06+/-0.42 versus 1.70+/-0.46 mm, P=0.0001). At follow-up (obtained in 91% of patients), angiographic restenosis rate was 21% in the stent group versus 47% in the balloon group (P=0.0001), a risk reduction of 55%. Repeat target lesion revascularization was less frequent in the stent group (13% versus 25%, P=0.0006). CONCLUSIONS Elective stent placement in small coronary arteries with focal de novo lesions is safe and associated with a marked reduction in restenosis rate and subsequent target lesion revascularization rate at 6 months.

Abstract
The purpose of this study was to compare the effects of stent placement with and without balloon predilatation on duration of the procedure, reduction of procedure-related costs, and clinical outcomes. Although preliminary trials of direct coronary stenting have demonstrated promising results, the lack of randomized studies with long-term follow-up has limited the critical evaluation of the role of direct stenting in the treatment of obstructive coronary artery disease. Between January and September 1999, 338 patients were randomly assigned to either direct stent implantation (DS+; 173 patients) or standard stent implantation with balloon predilatation (DS-; 165 patients). Baseline clinical and angiographic characteristics were similar in the 2 groups. Procedural success was achieved in 98.3% of patients assigned to DS+ and 97.5% of patients assigned to DS- (p = NS), with a crossover rate of 13.9%. Compared with DS-, DS+ conferred a dramatic reduction in procedure-related cost ($956.4 +/- $352.2 vs $1,164.6 +/- $383.9, p <0.0001) and duration of the procedure (424.2 +/- 412.1 vs 634.5 +/- 390.1 seconds, p < 0.0001). At 6-month follow-up, the incidence of major adverse cardiac events including death, angina pectoris, myocardial infarction, congestive heart failure, repeat angioplasty, or coronary artery bypass graft surgery was 5.3% in DS+ and 11.4% in DS- (p = NS). Multivariate analysis demonstrated that major adverse cardiac events rates were related to stent length of 10 mm (relative risk [RR] 3.25, 95% confidence intervals [CI] 1.36 to 7.78; p = 0.008), stent diameter of 3 mm (RR 2.69, 95% CI 1.03 to 7.06; p = 0.043), and complex lesion type C (RR 2.83, 95% CI 1.02 to 7.85; p = 0.045). Thus, in selected patients, this prospective randomized study shows the feasibility of DS+ with reduction in procedural cost and length, and without an increase in in-hospital clinical events and major adverse cardiac events at 6-month follow-up.

Abstract
OBJECTIVES In a multicenter, randomized trial, systematic stenting using the Wiktor stent was compared to conventional balloon angioplasty with provisional stenting for the treatment of acute myocardial infarction (AMI). BACKGROUND Primary angioplasty in AMI is limited by in-hospital recurrent ischemia and a high restenosis rate. METHODS A total of 211 patients with AMI <12 h from symptom onset, with an occluded native coronary artery, were randomly assigned to systematic stenting (n = 101) or balloon angioplasty (n = 110). The primary end point was the binary six-month restenosis rate determined by core laboratory quantitative angiographic analysis. RESULTS Angiographic success (Thrombolysis in Myocardial Infarction [TIMI] flow grade 3 and residual diameter stenosis <50%) was achieved in 86% of the patients in the stent group and in 82.7% of those in the balloon angioplasty group (p = 0.5). Compared with the 3% cross-over in the stent group, cross-over to stenting was required in 36.4% of patients in the balloon angioplasty group (p = 0.0001). Six-month binary restenosis (> or = 50% residual stenosis) rates were 25.3% in the stent group and 39.6% in the balloon angioplasty group (p = 0.04). At six months, the event-free survival rates were 81.2% in the stent group and 72.7% in the balloon angioplasty group (p = 0.14), and the repeat revascularization rates were 16.8% and 26.4%, respectively (p = 0.1). At one year, the event-free survival rates were 80.2% in the stent group and 71.8% in the balloon angioplasty group (p = 0.16), and the repeat revascularization rates were 17.8% and 28.2%, respectively (p = 0.1). CONCLUSIONS In the setting of primary angioplasty for AMI, as compared with a strategy of conventional balloon angioplasty, systematic stenting using the Wiktor stent results in lower rates of angiographic restenosis.

Abstract
Thallium-201 and technetium-99m-MIBI uptake are comparable in "maimed" (i.e., partially viable) and hibernating myocardium. The appreciation of myocardial viability should be based not only on the presence of a regional contractility improvement, but also on the evaluation of the initial level of contractility and of tracer uptake in the concerned area.

Abstract
The aim of this study was to assess the value of resting 99m Tc-Sestamibi scintigraphy for the detection of hibernating myocardium in zones of contractile dysfunction. Based on a series of 25 patients, 27 segments of supposedly hibernating myocardium were identified. All these segments corresponded to left ventricular wall motion abnormalities confirmed by contrast angiography and were perfused by a stenosed coronary artery: none of these zones were infarcted. Before revascularisation, comparison of the results of ventriculography and scintigraphy showed a correlation (p < 0.001) between the severity of regional contractile dysfunction appreciated by the center line method and the degree of myocardial hypofixation of 99m Tc MIBI. Three months after revascularisation, improvement of regional wall motion, assessed by control contrast angiography, was observed in 21 of the 27 segments studied (78%). Of these 21 segments, the viability of which was confirmed, 13 had a non-transmural uptake defect and 8 were normal on pre-revascularisation scintigraphy. The 6 segments without improvement at the 3 month control, had a transmural uptake defect on scintigraphy in 67% of cases. The authors concluded that when a residual uptake defect of 99m Tc sestamibi is present, viable myocardium may also be present.

Abstract
The myocardial uptake of rest-injected technetium 99m sestamibi on single-photon-emission computed tomographic images was assessed in 25 patients. All had an area of myocardial dysfunction that could be related to a coronary artery stenosis. None of the patients had clinical evidence of a myocardial infarction. Three months after revascularization, viability was demonstrated by contrast angiography and center-line analysis in 21 (78%) of the 27 formerly hibernating territories. Among these, none had a transmural defect, and 38% had a normal technetium 99m-sestamibi uptake. The four transmural preoperative defects were located in territories without viability. Eight of the 9 territories that were normal at scintigraphy proved to be viable postoperatively. It is concluded that as long as some residual technetium 99m-sestamibi uptake is present, viable myocardium is also present.

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
Silent ischaemic heart disease was looked for by exercise stress testing in 418 patients with chronic obliterative arterial disease of the lower limbs with no clinical or electrocardiographic signs of myocardial ischaemia. In the initial work-up, 6.2% of patients had a positive exercise test and the results were suspect in 9.2% of patients. These patients were followed up for 5 years. There were 42 deaths (10%). The cause of death was cardiovascular in 53.7% of cases (myocardial infarction 40.4%) and malignant disease in 35.7%. During the 5 year follow-up, ischaemic heart disease present as angina pectoris or myocardial infarction in 115 cases (27.5%). Patients who had a positive exercise stress test initially had a particularly high death rate (23%) and developed clinical signs of coronary insufficiency in 57.5% of cases. On the other hand, the peripheral vascular complications were relatively rare in this series: cerebrovascular accidents: 1.4%; retinal vascular accident: 1.1%; carotid surgery: 1.6%; lower limb amputation: 1.9%; lower limb vascular surgery: 17.7%. Silent ischaemic heart disease is very prevalent in patients with obliterative arterial disease of the lower limbs and is a main vital prognostic factor in these patients. These results confirm the need for a complete cardiovascular check-up in all patients with peripheral arterial disease.
