Abstract
OBJECTIVE to determine the time delay from symptom onset to diagnosis and treatment of patients with persistant ST segment elevation myocardial infarction (STEMI). DESIGN prospective observational study. METHOD patients with symptoms onset < 24 h admitted in all 10 cardiac intensive care units in one French administrative region (Alsace). Data were recorded by doctors on duty soon after hospital admission. Patients with STEMI during hospital stay or as a complication of cardiac interventional procedure were excluded. The Kruskal-Wallis test was used to assess statistical differences between the groups (p value < 0.05). RESULT from April to October 2004, 326 patients were admitted for STEMI. Median time between the symptoms onset and the patient's call for medical help was 60 minutes. General practitioners were the first medical contact in 41%. The time from symptoms onset to first medical intervention and from first medical intervention to coronary care unit admission were markedly shorter in patients who had directly called the Emergency Medical Services (group 15-110 patients i.e. 33% of the study population): 44 min vs 75 min otherwise (p=0,003). Median transport time was 60 min. Sixty two percent of the pts were transported by the Emergency Medical Services. The median time from symptoms onset to initiation of reperfusion therapy was 240 min. It was significantly lower in group 15 (170 min vs 286 min - p < 0,001) and for thrombolytic therapy (190 min versus 245 min for primary angioplasty, p=0,007). When thrombolysis (THL) was used, 89% of the pts could be treated during 6 hours of symptoms onset and 44% in 3 hours. For angioplasty only 4% of the pts were treated in the first 90 minutes, 9% in the 2 hours and 30% in the 3 hours of symptoms onset. If the time delay is evaluated from the 1 st medical intervention, call to reperfusion intervention was significatly shorter for THL: 91 versus 157 min, p< 0,003. Angioplasty represented 75% of reperfusion strategy in our area and THL alone only 2,7% and combine therapy 5,4%. CONCLUSION our study documents the beneficial effect of a direct call to Emergency Medical Services. Our results also underscore the need for an effort to reduce the time to offer the best appropriate reperfusion techniques in STEMI pts: speed up the admission in the cath-lab, think about pre-hospital thrombolysis followed by coronary angioplasty if necessary.

Abstract
OBJECTIVES Estimation of long-term outcome for patients suffering from acute myocardial infarction treated with primary angioplasty in an alsatian public center. PATIENTS AND METHODS Two-hundred and ninety-eight patients who underwent an urgent coronarography in a non-university center, with a view to immediate angioplasty, between January 1999 and December 2001. RESULTS Two-hundred and sixty-four patients (88.6%) were actually treated with urgent angioplasty, which has been successful in 87.1% of cases. Hospital mortality was of 7.7%. The population was composed of 16.4% patients older than 75 and of 11.7% patients with Killip 3 or 4 at admission. Mean follow-up was 34 months, lost to follow-up rate was of 4.7%. The global survival rate was of 78.9% and event-less survival rate of 41.9%. CONCLUSION Our results confirm the efficiency of angioplasty in real-life conditions as well at short-term as at long-term.

Abstract
A consecutive cohort including 1080 patients undergoing "off-pump" myocardial revascularization was reviewed. An average of 2.22 bypass/patients was performed. The death-rate during the first 30 days after surgery was 0.65%. Four cases needed cross-over to on-pump. The postoperative events were: need of inotropic drugs (2.7%), atrial fibrillation (12.4%), myocardial infarction (6.6%). The extubation was performed before the first postoperative 24 h in 91.9% of cases. The majority of patients was discharged from hospital before 8 days after surgery. Off pump coronary artery bypass surgery exhibit good results for most of the patients even if they present multiple vessel disease and high operating risk.

Abstract
The guidelines of the European Society of Cardiology, published in 2003, consider primary angioplasty as the preferred treatment strategy in acute coronary syndromes with ST-segment elevation, if the procedure can be performed within 90 min after first medical contact. We report the experience of three Alsacian centers running a common prospective registry with 2504 consecutive patients enroled between January 1999 and December 2004. The average age of the patients was 62 years with a proportion of 24% women. The time delay "pain to admission" was > or =3 hours in 55.9% of the cases. The treatment delay "door to catheterisation needle" was 59 min and the mean delay "door-to-reperfusion" was 79 min. The study population was representative of the real world including subsets of patients with a particulary high risk profile: age > or =70 years in 33%, a Killip grade > or =3 in 11.5%, rescucitated sudden death in 6.6% and cardiogenic shock in 10.9% of the patients respectively. The immediate procedural success rate (Timi 3 flow) in the treated coronary artery was 96.5%. The overall inhospital mortality-rate was 9.3%. The combinations of rescucitated sudden death--cardiogenic shock or age > or =75 years--cardiogenic shock were associated with a poor clinical outcome and mortality rates of 69% and 72.6% respectively, where as in the absence of abovementioned clinical high risk settings, the mortality rate was as low as 1.4%. The overall bleeding complication rate was 1.4%. The policy of systematic primary angioplasty in acute coronary syndromes with ST-Segment elevation appears to be coherent. The procedural complications and the in-hospital mortality rates were low, except in the presence of above mentioned clinical high risk settings.

Abstract
The objective of the study was to assess the frequency of late stent-thrombosis-related acute myocardial infarction in patients with LAD stents. A series of 930 PCI procedures involving LAD stenting were performed in 920 patients (mean age: 63 years, 667 men) from January 1999 to December 2001. Among those 14 patients had late (> 30 days), thrombosis-related acute myocardial infarction after a mean delay of 135 +/- 131 days. Three-year thrombosis-free survival was 97.6%. By univariate analysis, risk of late thrombosis was associated with LAD-diagonal bifurcation stenting, placement of a stent on the ostium of a diagonal branch and number of stents implanted on the LAD. Patients with these risk factors might be appropriate candidates for long-term combined antiplatelet therapy.

Abstract
OBJECTIVES From a prospective multicenter registry, we evaluated in three non-academic interventional cardiologic centers (Alsace/France), the coverage and the feasibility of the percutaneous coronary angioplasty (PTCA) in the acute phase of STEMI in the elderly (patients 75-years old and more). METHODS We studied clinical characteristics and angiographic data of patients older than 75 years, and the PTCA results: the revascularisation rates and the intrahospital events were analysed. These data were compared with those of the younger patients and confronted with the literature data. RESULTS Of a total of 1672 patients admitted for a STEMI, 342 (20.45%) were older than 75 years. These patients represented a high-risk group with a high proportion of women (50%), and many co-morbidities (e.g.: hypertension and diabetes mellitus), and three-vessel disease was found more often than in younger patients. Mortality rate was high in this subgroup and always more severe as compared to younger subjects, but remains variable according to the initial clinical profile. The global mortality was 20.47% but fell to 5.41% if we excluded the patients with cardiogenic shock, in Killip III and after resuscitation. PTCA is a coronary reperfusion technique particularly indicated in the management of the elderly presenting a STEMI. It is an effective technique in term of revascularisation, the reperfusion success (exclusively TIMI III flow) was indeed raised in the elderly even though it is lower than in younger patients (93.88 vs 97.18%). It is a quickly accessible technique, cath-lab accessibility provided, allowing a fast reperfusion and reducing hospitalization to a minimum. The management of the elderly presenting a STEMI has to focus on reducing the preadmission delay since this subgroup of patients hesitates to call the emergency (SMUR) when presenting an acute coronary symptomatology. The shorter the delay till admittance, the better the outcome. CONCLUSION PTCA is a technique particularly indicated in the elderly in Alsace because of regional specificities: first of all geographic (proximity of the SMUR for virtually all the population of Alsace), and secondly the medical infrastructure since the strategy of exclusive primary PTCA is granted by numerous interventional cardiologic teams. In Alsace, the proportion of elderly patients (> or = 75 years) is going to increase significantly with a parallel rise of STEMI--"a frightening perspective". We have to take into account this evolution, this reperfusion technique presenting numerous advantages and very few complications.

Abstract
OBJECTIVE AND METHOD Evaluation of angioplasty for primary cardiogenic shock in acute myocardial infarction in three non-universitary alsacians centres between 1999 and 2002. RESULTS One hundred and eighty-two patients were included. Hospitalisation survival rate is 43.96% after hospital discharge. One hundred and forty-nine patients were treated by primary angioplasty. Angioplasty is successful in 79.12%. The predictives factors of death are: age > 75, TIMI = 0 at the admission, three vessels disease. Twenty-four months survival is 91% (follow-up data available on 28.75% of the patients alive at hospital discharge). CONCLUSION Angioplasty seems to be the right choice in case of acute myocardial infarction complicated by cardiogenic shock, the results are better than medical treatment at short- and mid-term.

Abstract
UNLABELLED The FACT registry is currently the French registry including the greatest number of patients with acute coronary syndromes. PURPOSE The study presents epidemiologic data, modalities and delays for medical admission. METHOD Three thousand nine hundred and two patients were included in FACT by 362 French centers of cardiology between 06/01/2003 and 03/02/2003. One thousand eight hundred and ten patients, who had been placed in the cardiology departments of French general hospitals, were isolated from this registry. The French general hospitals represented 50.8% of the 362 centers. In order to clarify the study, these patients were divided into three groups: group A: patients without ST segment elevation but with suggestive ECG modifications; group B: patients with ST segment elevation; group C: all other patients. The results were mainly studied for groups A and B and compared. These results were also compared to those of the FACT registry and of other registries. RESULTS The results show that the average delay for admission is 2.9 h after a first delay between the pain and the help of 6.7 h. The first intervening party is a general practitioner (36.4%) then the SAMU (31.6%) and finally the emergency departments (18.7%). 16.6% of the patients from group B undergo pre-hospital thrombolysis. The recommendations of the European Society of Cardiology are widely applied except for the most recent of them since only 27.6% of the patients from group A having a TIMI score > or = 5 receive an anti-GIIB IIIA treatment. The reasons of the non-prescription of the recommended classes are mostly linked to contra-indication and intolerance. The strategy of coronary reopening mainly depends on the presence or the absence in the department of an available medical equipment for angioplasty. If there is one, the percentage of primary angioplasty reaches 54.2% and the percentage of thrombolysis 7.9%. On the opposite, there is 8.3% of angioplasty and 54.2% of thrombolysis for the unequipped centers. The global mortality reaches 5.8% but is inversely proportional to the level of equipment of the departments: 5.9% for the departments with angioplasty, 11% for the departments with coronarography but without angioplasty and 13.8% for the departments without any interventional equipment. Nevertheless, the age of the patients is different and this influences the results: we notice that the less equipped the department is, the older the patients are. CONCLUSION The FACT registry and the data from the general hospitals give the opportunity to think about the possibilities to improve the delays of call to the first intervening party (more particularly to the SAMU) but it also allows us to think about how to better organize the geographical distribution giving access to a medical equipment for angioplasty. All these information will also help the cardiologists to gather around the recommendations by convincing them that the benefit/risk ratio is positive.

Abstract
The annual inquiry by the "Angiography and Interventional Cardiology Group" of the French Society of Cardiology has allowed the evolution of interventional cardiology in France between 1991 and 2000 to be monitored. The results of the 2000 inquiry have been analysed in particular. The number of coronarography centres has increased by 27% in 10 years, growing from 173 in 1991 to stabilise at 220, and the number of centres performing percutaneous coronary angioplasty grew from 128 to 175 (+27%) at the same time. The number of coronarographies increased by 79% (131,636 to 236,111), and angioplasties increased by 197% (30,885 to 91,901). In the year 2000, angiographic procedures represented 39% of coronarographies, against 23% in 1991. Endoprosthesis implantation constitutes the principal revolution of this decade, the number of procedures growing from 393 to 77,388 between 1991 and 2000, some 84.2% of angioplasties, and a total number of endoprostheses of 107,869 (1.39 stents per procedure). The other revascularisation techniques remain anecdotal, representing only 1.9% of procedures. In 2000, at the 135 centres supplying detailed information, direct stenting represented 38.5% of procedures, and the indications for restenosis were 9.9%. The number of interventions performed in the public or private sector is almost identical for each category, only morphological or functional explorations remain the privilege of the public sector in the university setting. The activity of the University Hospitals Centres has noticeably and regularly decreased since 1991, falling from 39.2% to 28.7% of coronarographies and from 41.8% to 31.1% of angioplasties in 2000.

Abstract
This study presents data on the management of acute coronary syndromes collected in a national registry organized by the french Collège national des cardiologues des hôpitaux généraux in September 2000. In all 86 institutions participated and data from 607 patients (mean age: 67 years; 413 men) were analysed. The final diagnosis was unstable angina in 38%, non-Q wave myocardial infarction in 21% and Q-wave myocardial infarction in 40.5%. Median time to admission was 4 h. At symptom onset, patients called their general practitioners in 46% of cases, emergency ambulatory units in 31% of cases and arrived to the hospital on their own in 23% of cases. Observance of the European Society of Cardiology guidelines was good for patients without ST segment elevation. In patients with ST segment elevation, 9% had pre-hospital thrombolysis, 28% hospital thrombolysis, and 27% had angioplasty within 48 h of admission, including 9% with rescue angioplasty. Overall, 57% of patients with ST segment elevation received reperfusion therapy. In hospital mortality was 6% for the whole cohort, and 11% for patients with acute myocardial infarctions. By multivariate analysis, predictors of in-hospital mortality were age, type of acute coronary syndrome, absence of beta-blocker therapy, and absence of coronary angiography.

Abstract
A consecutive series of 746 patients undergoing heart beating myocardial revascularization was reviewed. An average of 2.30 grafts/patients was performed. The rate of mortality in the first 30 postoperative days was 0.28%. Two cases had to be terminated on-pump. We used the inotropic drugs in 0.6% of cases. The postoperative events were: atrial fibrillation (12.6%), myocardial infarction (0.3%). The rate of transfusion was 7.4%. The extubation was performed in the first 24 h postoperatively in 94.7% of cases. The majority of patients (91.3%) left the hospital in the first 8 d postoperatively. Off pump coronary artery bypass grafting gives good result for the most of the patients even for those with multiple vessel disease and high operating risk.

Abstract
OBJECTIVES We conducted an international, prospective, randomized, double-blind, placebo-controlled phase 2 trial in patients undergoing thrombolytic therapy or primary angioplasty for acute ST-elevation myocardial infarction (MI) to investigate the effect of eniporide on infarct size and clinical outcome. BACKGROUND Experimental studies suggest that the activity of the Na(+)/H(+) exchange (NHE) plays an important role in the unfavorable sequels of myocardial ischemia and reperfusion. Eniporide specifically inhibits the NHE-1 isoform and has been shown to limit infarct size in experimental models. METHODS The primary efficacy end point was the infarct size measured by the cumulative release of alpha-hydroxybutyrate dehydrogenase (alpha-HDBH) (area under the curve [AUC] 0 to 72 h). In stage 1, 50, 100, 150 or 200 mg eniporide given as a 10-min infusion before start of reperfusion therapy were compared with placebo in 430 patients, and in stage 2, 100 and 150 mg eniporide were compared with placebo in 959 patients. RESULTS In stage 1, the administration of 100 mg and 150 mg eniporide resulted in smaller infarct sizes (mean alpha-HBDH AUC in U/ml x h, placebo: 44.2, 100 mg eniporide: 40.2, 150 mg eniporide: 33.9), especially in the angioplasty group. In contrast, in stage 2 there was no difference in the enzymatic infarct size between the three groups (placebo: 41.2, 100 mg eniporide: 43.0, 150 mg eniporide: 41.5). Overall there was no effect of eniporide on clinical outcome (death, cardiogenic shock, heart failure, life-threatening arrhythmias). However, there was a significant reduction of the incidence of heart failure in patients reperfused late (>4 h). CONCLUSIONS In this large study administration of the NHE-1 inhibitor eniporide, before reperfusion therapy in patients with acute ST elevation MI, did not limit infarct size or improve clinical outcome.

Abstract
The Tenax coronary stent is laser sculpted from high precision 316 L stainless steel using advanced production procedures. An a-SiC: H (hydrogen-rich amorphous silicon carbide) coating reduces its thrombogenicity and improves its biocompatibility. From April to July 1998, 266 stents were implanted in 241 patients (aged 62.7 +/- 10.5 years) in five centers. The clinical indication for intervention was unstable angina (33.2%) and recent myocardial infarction (29.5%) in many cases. Most lesions (53.8%) had complex characteristics (Class B2 or C). The target vessel was the LAD in 42.5% and the right coronary artery in 36.8% of all cases. Four primary stent deployment failures occurred and implantation was successful in 259 (97.4%) of 266 stents. No death and no Q-wave myocardial infarction or emergency CABG occurred during hospital stay. Clinical success, defined as successful deployment without procedural or clinical event, was achieved in 230 (95.4%) of 241 patients. One-year clinical follow-up shows a low need for target lesion revascularization (17/237 [7.1%] patients) and a 15.8% rate of major adverse cardiac events (36/237 patients). The clinical and angiographic outcomes of our study suggest that the hybrid, amorphous hydrogenated silicon carbide coated design is promising and merits further evaluation in larger clinical trials.

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
The aims of myocardial revascularisation are to treat angina, reduce ischaemia and improve life expectancy. Patients with multivessel disease have a poor prognosis, especially when the lesions are proximal, when the preseptal left anterior descending artery is involved and when left ventricular dysfunction is present. In this particular group of patients, coronary bypass surgery has been shown to improve 10 year survival. Coronary angioplasty has been compared with surgical treatment in many clinical trials. The medium-term survival is the same in both groups, but with a higher number of repeat procedures except in diabetic patients in whom mortality is higher after angioplasty. The use of coronary stents should reduce the number of post-angioplasty procedures. Constant technical improvements, the introduction of surgery without cardiopulmonary bypass, combined revascularisation procedures, new antiplatelet drugs, the absence of long-term comparative results, all this results in a personalized choice of revascularisation procedure based on the overall clinical and angiography features of each particular case.

Abstract
Restenosis in the months following a successful percutaneous transluminal coronary angioplasty (PTCA) remains the main limitation to this technique for myocardial revascularisation. Despite intensive investigation in this area, no pharmacological therapy has yet been found to be useful in preventing restenosis after conventional balloon angioplasty. The occurrence of restenosis, which is now known to be caused by both vessel remodelling and neointimal hyperplasia, might be reduced in the future by a combined mechanical and pharmacological approach. Although systemic administration of 'antirestenosis' drugs has not yet been tested to prevent restenosis after coronary stenting, it is very likely that pharmacological inhibition of neointimal hyperplasia within coronary stents will take advantage of local delivery techniques. In addition to local drug delivery catheters that are available, the stent itself may be coated with polymers and serve as a platform for drug delivery. The continued attractiveness of PTCA, as an alternative to medical treatment or bypass surgery for patients with coronary artery disease, will depend upon our ability to control the restenotic process.

Abstract
Plasma noradrenaline is little used in evaluating the prognosis of cardiac failure because of the theoretical necessity of interrupting treatment for a few days before blood sampling. The present study reevaluated the prognostic value of this parameter with blood sampling performed during treatment and then 48 hours after withdrawal of treatment in 192 patients with chronic stable cardiac failure at an advanced stage (64% of patients in Classes III or IV with an average ejection fraction of 28.5 +/- 13.5%). During follow-up (average 43 months) there were 51 deaths and 17 transplants. None of the patients were lost to follow-up. Univariate analysis of 52 variable observers during the initial phase of evaluation found in decreasing order of predictive value for death plasma noradrenaline levels before and after withdrawal of treatment for 48 hours. Serum sodium, age, systolic mean and diastolic pulmonary artery pressures. In multivariate analysis: noradrenaline with or without withdrawal of treatment, hyponatraemia and systolic pulmonary artery pressure. Actuarial survival curves distinguished the following parameters: noradrenaline levels became predictive at concentrations of over 210 pg/mL and there was a significant difference in survival with respect to 4 levels of serum noradrenaline (with or without treatment) > 300 pg/mL, 300 to 600 pg/mL and > 900 pg/mL. This serum noradrenaline measured without withdrawal of treatment (especially angiotensin converting enzyme inhibitors) is a powerful predictor of mortality, carrying a progressively poorer prognosis as the concentration increases.

Abstract
This study was undertaken to determine the feasibility and safety of coronary stenting in acute myocardial infarction (AMI). In AMI, primary percutaneous transluminal coronary angioplasty (PTCA) is accepted as the preferred method of reperfusion for patients presenting at highly experienced centres. Until recently, however, stenting has been avoided during AMI because of a potential high risk of thrombosis. This prospective observational study carried out in 20 centres and included 648 consecutive patients who underwent PTCA with stent implantation for AMI. Of these 648 patients, 269 (41.5%, Group 1) were dilated early (< 24 hr) after the onset of the symptoms (75% treated by direct PTCA) and 379 (58.5%, Group 2) were dilated between 24 hr and 14 days after AMI. Combined therapy with ticlopidin and aspirin was used after the procedure. Bailout stenting occurred more often in Group 1 than in Group 2 (17% vs. 9.5%)(P < 0.05). Angiographic successful stenting was similar in both groups of patients (96% vs. 97%). During the hospital follow-up period, stent thrombosis occurred in eight patients (3%) in Group 1 and in six patients (1.6%) in Group 2 (NS). There was 14 deaths (5.2%) in Group 1 and 11 deaths (3.9%) in Group 2 (NS). After multivariate analysis bailout stenting was identified as the sole predictor of stent thrombosis (P < 0.0001). Vascular access-site complications occurred in six patients (1%) with no difference between the two groups. This study indicates that patients who receive a coronary stent in AMI can be managed safely with antiplatelet therapy. Randomized studies are needed to determine the precise indication for coronary stenting as an adjunct to primary PTCA.

Abstract
BACKGROUND Stenting reduces both acute complications of coronary angioplasty and restenosis rates but increases subacute thrombosis rates and hemorrhagic complications when used with coumadin anticoagulation. METHODS AND RESULTS To simplify postcoronary stenting treatment and to reduce these drawbacks, we evaluated the 1-month outcome of a prospective registry of 2900 patients in whom successful coronary artery stenting was performed without coumadin anticoagulation. Patients received 100 mg/d aspirin and 250 mg/d ticlopidine for 1 month. Low-molecular-weight heparin (LMWH) treatment was progressively reduced in four consecutive stages, from 1-month treatment to none. Event-free outcome at 1 month was achieved in 2816 patients (97.1%). Major stent-related cardiac events were subacute closure in 51 patients (1.8%), including death in 12 (0.5%), acute myocardial infarction in 17 (0.6%), and coronary artery bypass graft surgery in 9 (0.3%). Stent thrombosis was more frequent with balloon size of < 3.0 mm (< or = 2.5 mm, 10%; 3.0 mm, 2.3%; > or = 3.5 mm, 1.0%; P < .001), bail-out situations (6.67% versus 1.38%, P < .001), and patients with unstable angina or acute myocardial infarction (2.2% versus 1.12%, P = .02). Bleeding complications that required transfusion, surgical repair, or both occurred in 55 patients (1.9%). Bleeding complications were related to female gender (4.0% versus 1.51%, P < .001), duration of LMWH treatment (3.83% in phase II/III versus 0.69% in phase IV/V, P < .001), sheath size (6F, 0.52%; 7F, 1.04%; > or = 8F, 4.23%; P < .001), bail-out situations (4.76% versus 1.67%, P < .01), and saphenous graft stenting (4.38% versus 1.75%, P = .04). CONCLUSIONS These results suggest that poststenting treatment by ticlopidine/aspirin is an effective alternative to coumadin anticoagulation, achieving low rates of subacute closure and bleeding complications. LMWH treatment does not improve subacute reocclusion rates but increases bleeding complications. Furthermore, as bleeding complications were independently related to sheath size, we suggest that stenting with 6F guiding catheters may prevent local complications. Furthermore, the ticlopidine/aspirin combination allows a low-cost stenting strategy without ultrasound assessment of stent deployment and permits short inhospital stay.

Abstract
A registry was set up by the national college of cardiologists practicing in general hospitals in February 1993. The data concerned mode of admission, demographic details, initial clinical and haemodynamic evaluation and hospital outcome. Special attention was given to the electrocardiographic changes before and, in patients receiving thrombolytic therapy, after treatment. An analysis of predictive factors for mortality was performed both in the group of patients "revascularised" and in the group treated conventionally. One thousand and twenty three cases from 327 centres were analysed. There were 1292 men and 531 women, with an average age of 67.9 years. The average time interval from onset of symptoms to hospital admission was 5 h 30 min, 56.8% of patients arriving within 6 hours. 36.4% of the population underwent thrombolysis or angioplasty, 75% of patients under 75 years of age admitted before the 5th hours underwent a procedure of myocardial revascularisation. The hospital mortality was 14%, 8.7% in those revascularised and 17% in patients treated conventionally. Factors predictive of mortality were age, female gender, Killip Classes III or IV, systolic blood pressure of less than 100 mmHg, heart rate of more than 100/min and contraindications of thrombolysis. The maximum ST depression, the sum of ST depression, the sum of ST elevation and depression, were also significant predictive factors of a fatal hospital outcome in the whole population group and in patients treated conventionally. In the reperfused group, only the initial sum of ST elevation and depression was predictive of mortality: 120 minutes after the beginning of thrombolysis, the sum of ST elevations and of elevations and depressions was predictive of twice the mortality when the values exceeded 0.6 mv and 1.4 mv respectively.

Abstract
Platelet activation is accompanied by characteristic morphological changes: smooth-disc platelets become more spherical in shape and develop psudopods. The purpose of this study is to investigate whether platelets change after extracorporeal bypass. Twenty-two patients undergoing cardiopulmonary bypass (CPB) were studied prior to anesthesia and immediately after the operation. Platelets activated by different agonists were monitored simultaneously for morphological changes, ATP release and aggregation. While shape change measured before surgery was large, it was significantly reduced after bypass surgery (p < 0.01); morphological changes were quicker postoperatively. Several other parameters also changed: the time lapse between administration of the agonist and the start of ATP secretion decrease significantly (p < 0.01). After activation with high concentrations of ADP, ATP release was significantly increased (p < 0.01). On the other hand, less ATP was released after platelet activation with collagen and arachidonic acid, suggesting a change in platelet adhesion or a downregulation of endoperoxide synthesis. In our study, the importance of preactivation change in shape, estimated quantitatively by percent loss in ability of changing shape, can be compared using various agonists, with proportional defects in release and aggregation. These data provide evidence for different intrinsic levels in platelet defects after CPB.

Coronary angioplasty is sometimes thought to be insufficiently validated considering the considerable development it has undergone and its place in modern cardiological practice. Nevertheless, several randomised clinical trials comparing angioplasty with medical therapy in stable angina (ACME) and with surgical treatment in stable and unstable angina (RITA) have provided more scientific support for the technique. The serious perioperative complications have become rare, the limiting factor being restenosis which is responsible for a large number of clinical recurrences and the reappearance of documented myocardial ischaemia. It is therefore logical to make restenosis the first objective of evaluation of PTCA. There are two possible approaches to this problem. The first relies on automatic quantitative operator-independent angiography as a gold standard. However, this method is methodologically complex, technically fastidious and only takes into consideration the anatomical appearances, the correlations with clinical outcome and prognosis of which are poor. It allows measurement of the amplitude of the process which is an unquestionable advantage, but it is only a partial view of the problem. The second method considers that only stenosis causing ischaemia is significant and that the criterion of evaluation should be the rate of new events and that the necessity of repeated attempts at revascularisation is the criterion of failure of the method. This overlooks the possibility of an anti-restenosis drug producing clinical results independents of its anatomical effect. Both methods have their advantages and drawbacks, which necessitates using them both in all trials of new tools or new molecules designed to prevent restenosis.

Abstract
Complications arising during stent implantations in coronary arteries have been reduced by technological progress and the accumulated experience of interventional cardiologists. Retrospective and prospective randomized studies with several types of stents are currently available and show improved short and mid-term results. Wiktor stent provides increased flexibility for ease of implantation particularly in curved lesions. However, the flexibility of the Wiktor stent is also associated with low resistance in the longitudinal axis. We report four cases (in 4 out of 6 ostial lesions treated and 4 out of 43 Wiktor stents implanted during a 9-month period) in which stents have become unraveled during procedures on ostial lesions (2 saphenous venous grafts and 2 native coronary arteries). Death occurred in one case and one patient was treated by emergency coronary bypass surgery. In three cases the distal extremity of the guiding catheter stretched the stent meshes during the final control angiograms, and in one case the stent was stretched during withdrawal of the deflated balloon into the guiding catheter. We believe that it is preferable to avoid using this stent in ostial lesions.

Abstract
Spasm of healthy native coronary arteries is rare but a serious cause of perioperative ischaemia after coronary bypass surgery. The authors report five characteristic cases. In each case, the spasm presented with giant ST elevation and haemodynamic changes. In one case, further coronary bypass surgery was required. In three cases, symptomatic treatment of the hypotension associated with diltiazem completely cured the problem. One case was complicated by a small myocardial infarction. There were no fatalities. Previously reported cases often describe very heavy therapeutic protocols, justified by the high risks of this condition. Due to the fact that it is not possible to identify a target-population, simple prophylactic treatment with diltiazem seems to be justified in patients undergoing coronary artery bypass surgery.

Abstract
Intracoronary thrombolysis showed the chronological order of clinical electric and biological changes following the reestablishment of coronary flow. These changes make up the reperfusion syndrome; ST segment changes are part of this syndrome. They occur in practically all cases at the moment of reperfusion. The ST elevation may regress more or less rapidly or, on the contrary, increase transiently to a greater or lesser degree. When associated with other criteria of reperfusion-enzyme changes, arrhythmias, ST changes contribute to the indirect diagnosis of reestablishment of coronary flow. Rapid decrease in ST segment elevation is usually associated with a good myocardial outcome. The prognostic significance of transient increases in ST elevation--so called "reperfusion ischaemia"--is not fully understood, in particular its relationship to myocardial reperfusion injury. The myocardial prognosis after reperfusion may be the "biological" sum of cellular lesions due to ischaemia and reperfusion.

Abstract
A national enquiry carried out in 1990 in the departments of cardiology of general and private non-profit making hospitals established the status of these departments and the evolution of their personnel and equipment since their creation. The enquiry involved two thirds of the cardiology departments of the general hospitals (119/180) and showed that most (66%) were established between 1974 and 1988. Implanted in fairly important cities with catchment areas of 100,000 to 400,000 people, they have an average of 32 beds (range 11 to 100) and 7.25 coronary care beds (range 4 to 19); 347 doctors work full (211) or part time (136) in these departments. These two types of work are allowed in the majority of these units (64/119). Specialist certified cardiologists practice in 62 departments (56%). The usual technical equipment is available in 80% of the units (Doppler echocardiography, exercise stress testing, Holter monitoring, right heart catheterisation). Permanent pacing is performed in 65% of these hospitals, more so in the provinces than in the Paris region. Coronary angiography is only available in 21%, radioisotopic investigations in 15% and coronary angioplasty in 12% of these centres. A prospective study performed in 1990 concerning 110 hospitals recruited 1,030 myocardial infarctions, which enabled the total number of infarcts hospitalised in the coronary care units of the general hospitals to be estimated at about 21,000 (60% of French myocardial infarctions).

Abstract
BACKGROUND The value of thrombolytic therapy in unstable angina is unclear. METHODS AND RESULTS To study this problem, 159 patients were studied in a double-blind, placebo-controlled multicenter trial. Patients without a previous myocardial infarction, with a typical history of unstable angina, and ECG abnormalities indicative of ischemia were included. After baseline angiography, study medication (anistreplase or placebo) was given. Angiography was repeated after 12-28 hours. A significant decrease occurred in diameter stenosis between the first and second angiogram in the anistreplase group compared with the placebo group (11% versus 3%, p = 0.008). This difference was caused by reopening of occluded vessels in the thrombolytic group. However, no beneficial clinical effects of thrombolytic treatment were found. Bleeding complications were significantly higher in patients who received thrombolytic therapy (21 versus seven patients, p = 0.001). CONCLUSIONS Thus, angiographic but no clinical improvement after thrombolytic treatment with anistreplase was found in patients with unstable angina with an excess of bleeding complications. Therefore, thrombolytic treatment cannot be recommended in patients diagnosed as having unstable angina until proven otherwise.

Abstract
Myocardial infarction is an anatomical and therefore functional amputation of some of the myocardial tissues. Moments after acute coronary occlusion, a cascade of metabolic, mechanical and electrical ischaemia related events is observed. Contraction stops and regional left ventricular akinesis (then dyskinesis) occurs in the zone at risk of irreversible myocardial damage. This is partially compensated by hyperkinetic motion of non-ischaemic myocardium. The degree of alteration of the global ejection fraction is the resultant of these akinetic and hyperkinetic wall motions. It is lower in cases of anterior myocardial infarction, of occlusion of the proximal segment of the left anterior descending artery and of multivessel disease. Its eventual outcome depends on coronary blood flow. If the artery responsible is recanalized early, the global ejection fraction stabilises or improves. When this does not happen, the global ejection fraction decreases. The end-diastolic volume, an indicator of left ventricular remodeling, increases in relation to the size of the infarct and to the persistence of coronary artery occlusion. The delay before the appearance of the first irreversible lesions, the rate of their propagation within the myocardial wall and the presence of reperfusion lesions are poorly understood factors in the clinical setting and influence the efficacy of methods of myocardial protection.

Abstract
Myocardial reperfusion is associated with a number of clinical, electrocardiographic (arrhythmias, conduction defects, ST segment changes), haemodynamic and biological events. The commonest arrhythmias are ventricular extra-systoles, rapid ventricular tachycardias, and accelerated idio-ventricular rhythms. Reperfusion bradycardias are less common. When the arrhythmia is related to ischaemia it usually regresses when perfusion is restored. Reperfusion of the inferior wall of the left ventricle is often associated with sinus bradycardia and hypotension. The ST segment changes may evolve in two different ways: progressive regression or accentuation of ST elevation. When the responsible artery is recanalized, there is an immediate rise in plasma enzyme and myoglobin concentrations. The peak CPK concentration is usually observed after the 12th hours. The diagnostic value of the reperfusion syndrome lies in the interpretation of rapid ventricular tachycardias, accelerated idio-ventricular rhythms, ST segment changes and immediate rise in plasma CPK levels. The clinical risks of the reperfusion syndrome are low, practically never rhythmic and only exceptionally haemodynamic.

Abstract
IRS II (Invasive reperfusion study II) was a multicentre randomized trial comparing the efficacy of a 2-5-min 30 U anistreplase intravenous injection with a 1,500,000 U 60-min streptokinase (SK) intravenous infusion in acute myocardial infarction. 116 patients were randomized within 6 h of onset of symptoms. Early coronary patency was assessable in 107 patients by coronary angiogram performed 102 min after thrombolytic treatment (range: 30-297 min) in the anistreplase group and 93 min (range: 22-330 min) in the SK group. The early coronary patency rate was significantly higher in the anistreplase group than in the SK group: respectively, 70% (38/54) and 51% (27/53), P less than 0.05). Fifty patients had assessable coronary angiograms at 90 min and 24 h. The 24-h patency rate was 92.3% (24/26) in the anistreplase group vs 87.5% (21/24) in the SK group. No early reocclusion occurred in the anistreplase group vs 15.4% (2/13) in the SK group (NS). Fibrinogen fell to 13.2 +/- 19.8% on anistreplase vs 9.4 +/- 10.3% on SK (NS). Bleeding complications occurred in 12% (7/58) of treated patients in the anistreplase group vs 20.7% (13/58) in the SK group (NS). Two cerebrovascular accidents occurred after thrombolytic treatment with anistreplase (3.4%) vs one after SK (1.7%) (NS). Thus, anistreplase is more effective than intravenous SK and easier to administer.

Abstract
The authors report their preliminary results with the Rotacs system in the reopening of chronic coronary artery occlusion by low-speed rotational angioplasty. This system improves the percentage of coronary recanalisation in cases where it is impossible to pass the guide wire alone. It seems to be an effective, low-cost complementary tool for the treatment of this type of lesion.

Abstract
Thirteen years after its introduction transluminal balloon catheter angioplasty is a widely used technique. Owing to major technological advances and to the experience acquired by surgical teams, the primary success rate now reaches 90 p. 100. Hospital mortality has fallen down to 1 p. 100 and the need for emergency aorto-coronary bypass has been reduced to 4 p. 100 of the cases. However, despite repeated attempts at pharmacological or mechanical prevention, the restenosis rate remains around 30 p. 100. Coronary angioplasty is part of a wider strategy of myocardial reperfusion. Its indications are roughly the same as those of surgery. In patients with one-vessel coronary disease angioplasty is the first choice treatment, except for unprotected restenosis of the common trunk or very proximal lesions of the anterior interventricular artery. In multiple vessel disease the more complex the anatomical situation the more pronounced the left ventricular dysfunction and the greater the need for surgery. The acute phase of myocardial infarction is a legitimate indication for angioplasty, notably when thrombolytic agents are contraindicated or have failed when given intravenously, or in case of recurrence after an initially successful thrombolysis.

Abstract
Coronary recanalisation rate is one of the parameters utilized to evaluate the effectiveness of a thrombolytic agent. This parameter can only be measured when the occlusion and reopening of the coronary artery involved are demonstrated by angiography. Moreover, this type of study enables the kinetics of drug activity to be accurately determined. When injected intravenously in doses of 30 units less than four hours after the onset of chest pain and when studied by this method, Eminase produces recanalisation in more than 60 per 100 of the cases. The time elapsed between injection and action is 45 minutes on average. The risk of early reocclusion is low (about 5%). The recanalisation rate obtained with Eminase is similar to that obtained with intracoronary streptokinase.

Abstract
In a multicentre randomized open study conducted on two parallel groups the effectiveness of APSAC was compared with that of streptokinase (SK) in 116 cases of myocardial infarction treated during the first 2.75 hours. APSAC (30 IU) was administered by intravenous bolus injection over 2 to 5 minutes, and SK (1.5 million IU) by intravenous infusion over 60 minutes. The patency of the coronary artery responsible for myocardial infarction was evaluated by coronary arteriography performed 1.74 h on average after the beginning of treatment; it was 70 p. 100 in the APSAC group and 51 p. 100 in the SK group (p less than 0.05). The fall in plasma fibrinogen was similar in both groups (mean minimum level; 0.2 g/l). Haemorrhages occurred in 9/58 patients treated with APSAC (15.5 p. 100) and in 13/58 patients treated with SK (22.4 p. 100); these haemorrhages took place during the first 24 hours in 4 patients of the APSAC group and in 10 patients of the SK group. Five patients died: 2 in the APSAC group and 3 in the SK group. In a subgroup of 38 patients who underwent 3 control coronary arteriographies (at 90 min, 24 hours and 3 weeks), the patency rates were 63 p. 100, 82 p. 100 and 93 p. 100 respectively with APSAC and 44 p. 100, 86 p. 100 and 92 p. 100 respectively with SK (NS). No coronary reocclusion occurred in the APSAC group, as against 3 (1 early, 2 delayed) in the SK group. It is concluded that APSAC seems to be more effective than intravenous streptokinase; it is easier to administer (bolus injection) and does not carry a higher risk of haemorrhage.

Abstract
Idiopathic bilateral atrial dilatation is extremely rare. We are reporting a case in a 79 year-old patient, presenting a picture of total cardiac insufficiency. The positive diagnosis was established by bi-dimensional sonography and right angiography. Nuclear magnetic resonance confirmed the diagnosis and specified the size of the various cavities. From a rhythm standpoint, there was an atrial fibrillation without conduction disorders. The main factor of the cardiac insufficiency seems to be a low atrio-ventricular output, since the valvular insufficiency due to annular dilatation is only a secondary factor. The etiology is unknown, but a congenital origin seems most probable without excluding the possibility of an acquired structural disorder.

Abstract
An unusual case of transient electro-mechanical dissociation concomitant with myocardial reperfusion is reported. The patient had myocardial infarction caused by occlusion of the middle anterior interventricular artery relieved by injection of urokinase and plasminogen in situ. The dissociation could be documented by simultaneous ECG recording on 3 leads and direct intravascular recording of femoral arterial pressure, the patency of that artery, and its maintenance, being demonstrated by angiography. This clinical case can be added to the list of events which occur during reperfusion of the myocardium after prolonged ischaemia. Its mechanisms, so far, are purely conjectural.

Abstract
86 patients with a first myocardial infarction presenting within 6 hours of the onset of symptoms were randomly allocated to treatment with intravenous streptokinase or anisoylated plasminogen streptokinase activator complex (APSAC). Side effects were observed in 34.1% of patients (15 of 44) in the streptokinase group and 23.8% (10 of 42) in the APSAC group. These effects included injection related effects (in 4 patients on streptokinase versus 6 on APSAC) and neurological complications (0 vs 2 patients, respectively). Femoral haematoma accounted for the majority of bleeding events. Death occurred as a consequence of haemorrhage in 2 patients (1 receiving streptokinase and the other APSAC).
