Predictive criteria for acute heart failure in emergency department patients with acute dyspnoea: the PREDICA study.

OBJECTIVES: The early identification of patients with Acute Heart Failure Syndrome (AHFS) among patients admitted to the Emergency Department (ED) with dyspnoea can facilitate the introduction of appropriate treatments. The objectives are to identify the predictive factors for AHFS diagnosis in patients with acute dyspnoea (primary objective) and the clinical 'gestalt' (secondary objective) in ED. METHODS: PREDICA is an observational, prospective, multicentre study. The enrolment of patients admitted to the ED for nontraumatic acute dyspnoea and data collection on admission were recorded by the patient's emergency physician. The AHFS endpoints were assessed following a duplicate expert evaluation by pairs of cardiologists and emergency physicians. Step-by-step logistic regression was used to retain predictive criteria, and the area under the receiver operating characteristic (ROC) curve of the model was constructed to assess the ability of the selected factors to identify real cases. The probability of AHFS was estimated on a scale from 1 to 10 based on the emergency physician's perception and understanding (gestalt). RESULTS: Among 341 patients consecutively enrolled in three centres, 149 (44%) presented AHFS. Eight predictive factors of AHFS were detected with a performance test showing an area under the model ROC curve of 0.86. Gestalt greater than or equal to five showed sensitivity of 78% and specificity of 90% (AUC 0.91) and diagnosed 88% of AHF in our population. CONCLUSIONS: We identified several independant predictors of final AHFS diagnosis. They should contribute to the development of diagnostic strategies in ED. However, unstructured gestalts seem to perform very well alone.

Intramyocardial transplantation of mesenchymal stromal cells for chronic myocardial ischemia and impaired left ventricular function: Results of the MESAMI 1 pilot trial.

BACKGROUND: The MESAMI 1 trial was a bicentric pilot study designed to test the feasibility and safety of intramyocardially injected autologous bone marrow-derived mesenchymal stromal cells (MSCs) for the treatment of ischemic cardiomyopathy. METHODS AND RESULTS: The study included 10 patients with chronic myocardial ischemia, left ventricular (LV) ejection fractions (EFs) of ≤35%, and reversible perfusion defects who were on stable optimal medical therapy and were not candidates for revascularization. MSCs (mean: 61.5×10(6) cells per patient) were injected into 10-16 viable sites at the border of the LV scar via a NOGA-guided catheter. Both primary endpoints, feasibility (successful harvest, expansion, and injection of autologous MSCs) and safety (absence of severe adverse events [SAEs]) were met in all 10 patients at the 1-month follow-up time point, and none of the SAEs reported during the full 2-year follow-up period were attributable to the study intervention. The results of secondary efficacy endpoint analyses identified significant improvements from baseline to Month 12 in LVEF (29.4±2.0% versus 35.7±2.5%; p=0.003), LV end-systolic volume (167.8±18.8mL versus 156.1±28.6mL; p=0.04), 6-min walk test and NYHA functional class. CONCLUSIONS: Our results suggest that autologous MSCs can be safely administered to the hearts of patients with severe, chronic, reversible myocardial ischemia and impaired cardiac function and may be associated with improvements in cardiac performance, LV remodeling, and patient functional status. A randomized, double blind, multicenter, placebo-controlled clinical trial (MESAMI 2) will evaluate the efficacy of this treatment approach in a larger patient population. CLINICAL TRIAL REGISTRATION: Unique identifier: NCT01076920.

No post-conditioning in the human heart with thrombolysis in myocardial infarction flow 2-3 on admission.

AIMS: Proof-of-concept evidence suggests that mechanical ischaemic post-conditioning (PostC) reduces infarct size when applied immediately after culprit coronary artery re-opening in ST-elevation myocardial infarction (STEMI) patients with thrombolysis in myocardial infarction 0-1 (TIMI 0-1) flow grade at admission. Whether PostC might also be protective in patients with a TIMI 2-3 flow grade on admission (corresponding to a delayed application of the post-conditioning algorithm) remains undetermined. METHODS AND RESULTS: In this multi-centre, randomized, single-blinded, controlled study, STEMI patients with a 2-3 TIMI coronary flow grade at admission underwent direct stenting of the culprit lesion, followed (PostC group) or not (control group) by four cycles of (1 min inflation/1 min deflation) of the angioplasty balloon to trigger post-conditioning. Infarct size was assessed both by cardiac magnetic resonance at Day 5 (primary endpoint) and cardiac enzymes release (secondary endpoint). Ninety-nine patients were prospectively enrolled. Baseline characteristics were comparable between control and PostC groups. Despite comparable size of area at risk (AAR) (38 ± 12 vs. 38 ± 13% of the LV circumference, respectively, P = 0.89) and similar time from onset to intervention (249 ± 148 vs. 263 ± 209 min, respectively, P = 0.93) in the two groups, PostC did not significantly reduce cardiac magnetic resonance infarct size (23 ± 17 and 21 ± 18 g in the treated vs. control group, respectively, P = 0.64). Similar results were found when using creatine kinase and troponin I release, even after adjustment for the size of the AAR. CONCLUSION: This study shows that infarct size reduction by mechanical ischaemic PostC is lost when applied to patients with a TIMI 2-3 flow grade at admission. This indicates that the timing of the protective intervention with respect to the onset of reperfusion is a key factor for preventing lethal reperfusion injury in STEMI patients. CLINICAL TRIAL NUMBER: NCT01483755.

Plaque rupture and morphological characteristics of the culprit lesion in acute coronary syndromes without significant angiographic lesion: analysis by intravascular ultrasound.

PURPOSE: To evaluate by intravascular ultrasound (IVUS) the characteristics of the culprit lesion with plaque rupture without significant angiographic stenosis after acute coronary syndromes (ACS). PATIENTS AND METHODS: After ACS, IVUS was performed in 68 patients (46.8 years±11.9) without significant angiographic stenosis (31±15%). Plaque rupture was defined as a cavity within the plaque, communicating with the arterial lumen and having an overlying residual fibrous cap fragment. Qualitative analysis defined the type of plaque, and quantitative analysis evaluated plaque plus media area, plaque volume, plaque burden, and arterial remodeling index. Patients were divided into two groups: Group I with plaque rupture (25 patients) and Group II without plaque rupture (43 patients). RESULTS: All patients with rupture showed soft or mixed plaque but no calcified plaque. In Group I, plaque rupture was associated with a larger plaque burden (49.8±12.3% vs. 39.8±12.1%, P<.0005), a more significant plaque plus media area (7.44±2.9 vs. 5.24±2.4mm(2), P<.001), a greater plaque volume (151.9±103.4 vs. 99.2±81.6mm(3), P<.007), and a higher ratio of plaque volume over length (8.0±3.8 vs. 5.6±3.7mm(3)/mm, P<.003). In Group I, positive remodeling was more frequent than intermediate remodeling (P<.03) or negative remodeling (P<.005). In Group II, there was no significant difference between the three types of remodeling. CONCLUSION: The plaque ruptures responsible for ACS frequently appear on voluminous plaques with a large plaque burden and positive arterial remodeling.

Subarachnoid haemorrhage associated with midventricular Tako-Tsubo syndrome.

BACKGROUND: A new form of Tako-Tsubo cardiomyopathy has recently been described as a midventricular localisation, opposite to the apical typical form. CASE REPORT: We report the case of a patient who presented with a sudden cardiac death and an acute coronary syndrome. However, coronary arteries were normal and the left ventriculography showed a midventricular ballooning Tako-Tsubo syndrome associated with a hawk's beak. A cerebral CT scan revealed a massive subarachnoid haemorrhage in relation with a left sylvian aneurysm rupture leading to the death of the patient. CONCLUSION: This case relates for the first time, the association of a subarachnoid haemorrhage and the recently described midventricular form of Tako-Tsubo syndrome with a hawk's beak. It is an illustration of the complexity of the relationships between brain and heart.

Long-term clinical outcome after percutaneous coronary interventions in the elderly: results for 512 consecutive patients.

AIMS: Elderly patients are increasingly being referred for percutaneous coronary intervention (PCI), but there is a paucity of current data on the long-term outcome of elective PCI in elderly patients. We sought to define the risks facing elderly patients undergoing contemporary PCIs. METHODS AND RESULTS: Retrospectively, in a single-centre registry, we studied the mortality and the outcome of 512 consecutive patients > 75 years old who underwent PCI, between January 1st 2000 and December 31st 2001. Clinical endpoints included in-hospital mortality; major adverse cardiovascular and cerebro-vascular events (MACCE) defined by the components of death, myocardial infarction, stroke, and repeat coronary revascularisation (target vessel revascularisation or not) by surgery or PCI, within the hospitalisation period and at long-term follow up. We compared 315 patients 75-79 years old (group I) with 197 patients > 80 years old (group II). In-hospital mortality and MACCE rates were not different between the two groups. Independent predictors of in-hospital major events found by multivariate analysis were: ST-segment elevation myocardial infarction or STEMI (Odds Ratio [OR]=2.58, 95% CI=1.15-5.78), left ventricular ejection fraction or LVEF <40% (OR=4.98, 95% CI=2.19-11.36) and prior coronary artery bypass grafting or CABG (OR=3.13, 95% CI=1.06-9.26). Mean long-term follow-up was 51.3 months. Death was significantly more frequent in the older group (42% vs 26%, p<0.0001). Independent predictors of long-term mortality found by multivariate analysis were: LVEF < 40% (Hazard Ratio=4.12, 95% CI=2.69-6.32), creatinine rate (HR=1.00, 95% CI=1.00-1.006) use cut-off see table and prior carotid surgery or stroke (HR=2.2, 95% CI=1.19-4.14). CONCLUSIONS: Although age is not an independent predictive factor of morbidity or mortality, co-morbidities in the elderly strongly influence long-term clinical outcomes after PCI.

NMR and cDNA array analysis prior to heart failure reveals an increase of unsaturated lipids, a glutamine/glutamate ratio decrease and a specific transcriptome adaptation in obese rat heart.

Obesity is a risk factor for heart failure through a set of hemodynamic and hormonal adaptations, but its contribution at the molecular level is not clearly known. Therefore, we investigated the kinetic cardiac transcriptome and metabolome in the Spontaneous Hypertensive Heart Failure (SHHF) rat. The SHHF rat is devoid of leptin signaling when homozygous for a mutation of the leptin receptor (ObR) gene. The ObR-/- SHHF rat is obese at 4 months of age and prone to heart failure after 14 months whereas its lean counterpart ObR-/+ is prone to heart failure after 16 months. We used a set of rat pangenomic high-density macroarrays to monitor left ventricle cardiac transcriptome regulation in 4- and 10-month-old, lean and obese animals. Comparative analysis of left ventricle of 4- and 10-month-old lean rat revealed 222 differentially expressed genes while 4- and 10-month-old obese rats showed 293 differentially expressed genes. (1)H NMR analysis of the metabolome of left ventricular extracts displayed a global decrease of metabolites, except for taurine, and lipid concentration. This may be attributed to gene expression regulation and likely increased extracellular mass. The glutamine to glutamate ratio was significantly lower in the obese group. The relative unsaturation of lipids increased in the obese heart; in particular, omega-3 lipid concentration was higher in the 10-month-old obese heart. Overall, several specific kinetic molecular patterns act as a prelude to heart failure in the leptin signaling deficient SHHF obese rat.

[Angiotensin receptor blockers and cardiac rhythm disorders]. / Antagonistes des récepteurs de l'angiotensine II et troubles du rythme.

Angiotension Receptor Blockers (ARB) are able to prevent the occurrence of atrial fibrillation (AF) through various mechanisms among them: neurhumoral antagonism and hemodynamic control. This occurs during arterial hypertension and chronic heart failure both diseases known to be associated with left atrial dysfunction. In the CHARM program, candesartan reduced by 20% the incidence of AF and thus also mortality and the incidence of hospitalisation for heart failure related to AF This beneficial effect is also observed with ACE inhibitors but is more important and potentated by ARB. In the Val-Heft study, valsartan on the top of standard treatment including ACE inhibitors, significantly lowered the cases of AF In hypertensive patients, ARB are more powerful than ACE inhibitors for the prevention of AF In the LIFE study, patients in the losartan arm had 33% less AF than patients from the other arm, despite treatment with atenolol and similar blood pressure reduction. Moreover ARB beside their specific effects are also able to increase efficiency of anti-arrhythmic agent; since after cardioversion patients treated with amiodarone plus irbesartan had a lower rate of recurrence of atrial fibrillation than patients treated with amiodarone alone. Finally ARB may reduce the risk of sudden death by ventricular arrhythmias in patients with diabetes mellitus.

[Cardiac asystole during acute anterior myocardial infarction: a consequence of endocardiac reflexes]. / Asystolie en phase aiguë d'infarctus du myocarde antéroseptal: une manifestation de la mise en jeu de réflexes endocardiaques.

The authors report a case of paroxysmal, complete atrioventricular block during an anterior acute myocardial infarction, leading to asystolia. The different possible physiopathological mechanisms are discussed, suggesting a paroxysmal nodal conduction defect, secondary to transient parasympathetic stimulation, triggered by a Bezold-Jarish type of cardiac reflex. This reflex is frequently involved in various pathologic situations or diagnostic procedures, usual in cardiology. Although it is frequently observed in inferior myocardial infarction, it can occur during an anterior acute myocardial infarction.

[Myocardial infarction in a young female smoker taking oral contraception]. / Infarctus du myocarde chez une jeune femme fumeuse sous contraception orale.

A 33 year old woman suffered a lateral myocardial infarction for the first time, and was treated by pre-hospital thrombolysis and secondary angioplasty on the diagonal artery. Fifteen days before the cardiac event she had undergone a left ovarian cyst excision and left salpingectomy for an ectopic pregnancy. She was a moderate smoker and had been taking a second-generation biphasic minidose oral contraceptive (ethinyl-estradiol 30-40mg and levonorgestrel 150-200 mg) for about ten years. Fifteen days before the myocardial infarction and due to the ectopic pregnancy she had changed to a combined monophasic minidose oral contraceptive pill containing ethinylestradiol (30 mg) and drospirenone (3 mg). The eventual outcome was favourable, with no complications. In this article we discuss the possible implications of the various factors (oral contraceptive, tobacco use, and surgical intervention) in this young woman with a myocardial infarction.

[Identification of viable myocardium in ischemic heart disease with severe left ventricular contractile dysfunction: comparison of myocardial scintigraphy with 99mTc-sestamabi and with 201-thallium]. / Identification du myocarde viable dans les cardiopathies ischémiques avec atteinte sévère de la fonction contractile du ventricule gauche: comparaison de la scintigraphie myocardique <> au 99mtechnétium-sestamibi et de la scintigraphie myocardique au 201thallium.

The aim of this study was to compare quantitatively uptake of 99mTc-Sestamibi at rest and that of late redistribution of 201Tl in the same patients with severe ischaemic left ventricular dysfunction, and to correlate the uptake of the tracer to regional ventricular dysfunction studied by ECG grated 99Tc-Sestamini. A double isotope myocardial scintigraphy, 201 Thallium at rest/redistribution and 99Tc-Sestamibi at rest and on exercise, was performed in 28 patients with severe postinfarction ischaemic cardiomyopathy (EF= 29 +/- 4%). Quantitative analysis for each patient and each isotope were performed with respect to the number of hits expressed in percentage of the activity of a normal zone in 17 circumferential profiles distributed in 4 zones, that is to say in 476 segments. A score allowed counting of viable and non-viable segments and evaluation of contractile function of the 17 segments with respect to wall motion and systolic thickening. Total concordance of global uptake of the two isotopes was observed in 430 of the 476 segments (90.3%) (r= 0.814, p< 0.0001), but the 99mTc-Sestamibi uptake was less than 201 Th (71 +/- 23% vs 73 +/- 21%, p= 0.0001). With respect to left ventricular wall motion, uptake of 99mTc-Sestamibi was greater than that of 201Tl in normal or hypokinetic segments but less in akinetic and dyskinetic segments. The difference between the two isotopes was most marked in segments with very severe contractile dysfunction. The authors conclude that the uptake of 99mTc-Sestamibi is correlated with that of late distribution of 201Tl when left ventricular contraction is not too poor and should no longer be considered as only a marker of perfusion but can also be useful in the investigation of myocardial viability.

[Cardiac cellular therapy: from cells to the first clinical uses]. / Thérapie cellulaire cardiaque: des cellules aux premières indications cliniques.

Despite the improvement in revascularisation techniques, coronary artery disease remains the principal aetiology of cardiac failure in developed countries. The therapeutic management of cardiac failure has been improved over recent years, yet cardiac failure is still associated with significant morbidity and mortality. As cardiac transplantation lacks donors, techniques that allow myocardial regeneration represent an attractive alternative. To date, several types of cells are under study and are suitable for implantation into infarcted myocardium (myoblasts, medullary stem cells...). Following good preclinical study results, the first human cell therapy trials, using the intramyocardial route, have begun, in the course of aorto-coronary bypass surgery in patients with chronic ischaemic cardiopathy and little altered left ventricular function, and then in those with ventricular dysfunction. Different modes of administration of these cell therapy products are under study and could be envisaged in clinical situations such as just after infarction in order to improve ventricular remodelling with an intracoronary injection technique. As for every new treatment, there are numerous problems to resolve, from understanding the relevant mechanisms of cellular transplantation, to the secondary effects that it could entail. Nevertheless, cardiac cellular transplantation is expanding rapidly and with the evolution of techniques it allows a glimpse of a new field of treatment for cardiac failure.

[Therapeutic education for cardiac failure patients: the I-care programme]. / Education thérapeutique des patients insuffisants cardiaques: le programme I-care.

Therapeutic education is becoming increasingly important in the management of chronic diseases including cardiac failure. The I-CARE programme consists of an evaluation of the role of therapeutic education in France, creating standardised tools and setting up training sessions for therapeutic education in the context of cardiac failure. Approximately two thirds of the French centres contacted perform therapeutic education with their available means. The lack of personnel, space, and training tools represent obstacles to the development of therapeutic education. The tools developed in the programme fall into 5 areas: diagnosis education, understanding the illness, diet, physical activity/daily life, and treatment. Training sessions were organised for the teams, consisting of at least one cardiologist and nurse. The I-CARE programme should allow the expansion of therapeutic education for cardiac failure and improve the multidisciplinary management of this disease which increasingly affects often elderly subjects.

[Long-term follow-up after primary angioplasty: is stenting beneficial?]. / Angioplastie primaire a long-terme: quel bénéfice des endoprothèses?

BACKGROUND: Primary stenting leads to a better short-term outcome than balloon angioplasty for acute myocardial infarction in randomised trials. However few data are available about the long-term outcome of primary stenting in acute myocardial infarction (AMI). OBJECTIVES: The aim of this study was to compare the three-year outcome after primary stenting versus balloon angioplasty in patients with acute myocardial infarction. METHODS: We conducted a retrospective study including 157 patients with AMI in a single center. Patients underwent balloon angioplasty (N = 48) or primary stenting (N = 109) within six hours after the onset of chest pain. We looked at the outcome during three years focusing on global mortality, major adverse cardiac events (MACE), reinterventions and target vessel revascularization (TVR). RESULTS: The two groups are similar for their baseline characteristics. No difference was noted for in-patient mortality in the balloon angioplasty group and the primary stenting group (2.1 vs 2.8%; P = ns). The three-year mortality was not significantly different in the two groups. Regarding MACE (27.8 vs 31.7; P = 0.95), reinterventions (20.4 vs 24.7%; P = 0.98) and TVR (18.6 vs 17.8%; P = 0.69), both groups were statistically not different. CONCLUSION: In the long-term patients treated with stent placement have similar rates of MACE, reinterventions or TVR than patients undergoing balloon angioplasty. If few studies noted a benefit in short-term outcomes, primary stenting doesn't improve the prognosis of acute myocardial infarction on long-term follow-up, which is dependent on atherosclerosis.

[Obesity and cardiac failure]. / Obésité et insuffisance cardiaque.

Obesity alone is the cause of 11% of cases of cardiac failure in men and 14% of cases in women in the United States. The frequency of obesity continues to rise in our country, 41% of our compatriots being obese or overweight. It is expected that obesity will become an important cause of cardiac failure in the coming years. The Framingham study showed that, after correction for other risk factors, for every point increase in body mass index, the increase in risk of developing cardiac failure was 5% in men and 7% in women. There are three physiopathological mechanisms to explain the adverse effects of obesity on left ventricular function: an increase in ventricular preload secondary to increased plasma volume induced by the high fatty mass; an increase in left ventricular afterload due to the common association of hypertension generated by activation of the sympathetic nervous system by hyperinsulinism; and systolic and diastolic dysfunction due to changes in the myocardial genome and coronary artery disease induced by risk factors of atherosclerosis aggravated by obesity. The adipocyte also secretes a number of hormones which act directly or indirectly on the myocardium: angiotensin II, leptin, resistin, adrenomedulin, cytokines. These haemodynamic and hormonal changes profoundly modify the genetic expression of the myocardium in obesity, favourising hypertrophy of the myocyte and the development of interstitial fibrosis. Whether it be eccentric in the absence of hypertension or concentric when hypertension is associated with obesity, left ventricular hypertrophy, although normalising left ventricular wall stress, has adverse consequences causing abnormal relaxation and decreased left ventricular compliance. Therefore, in obese patients, two forms of cardiac failure may be observed. The more common is due to diastolic dysfunction, obesity being one of the principal causes of cardiac failure with preserved systolic function. Cardiac failure due to systolic dysfunction is less common and may be observed in cases with inappropriate left ventricular hypertrophy which does not normalise abnormal left ventricular wall stress leading to cardiomyopathy, and in cases with associated coronary artery disease. Whatever the underlying mechanism, the diagnosis of cardiac failure is made more difficult by obesity. From the prognostic point of view, in the global population of patients with cardiac failure, obesity improves survival because it counteracts the adverse effect of cachexia; however, obesity increases the risk of sudden death. In fact, obesity is associated with dynamic change in QT interval. In cases of cardiac failure secondary to obesity-related cardiomyopathy, loss of weight leads to an improved functional status and a reduction of left ventricular remodelling and an increase of the ejection fraction.

[Prognosis scores to help revascularization for ischemic heart failure]. / Scores pronostiques pour la revascularisation des myocardiopathies ischémiques.

AIMS: Patients suffering from coronary heart disease with ventricular systolic dysfunction present a bad prognosis and should be potentially revascularized. Up to now, surgery appeared to be the most feasible revascularization technique for such patients. Aims of this study were to assess the influence of different treatments (surgery, angioplasty or exclusively medical treatment) on clinical outcome and to establish a prognostic score practitioners to select the most appropriate therapy adapted to their patient profiles. METHOD: From 1995 to 2000, 492 patients were included in this cohort: 365 in the angioplasty group, 96 in the surgical group and 31 in the medical group. Kaplan Meier curves were made with a multivariate analysis to determine the significant predictive factors of mortality and major adverse cardiac events. RESULTS: After a mean follow-up of 32 +/- 19 months, there was no statistical difference in mortality rate between the groups. However, the survival rate without MACE is higher in the surgical group, intermediate in the angioplasty group and lower in the medical group. Using the significant predictive factors of MACE in multivariate analysis, a prognostic score has been established in order to discriminate three categories of severity. For each category, angioplasty was compared with surgery in terms of the event-free-survival rate. For the two extreme categories (severe and non-severe), both treatments were equal. For the intermediate category, surgery obtained greater results. CONCLUSION: This prognostic score could help physicians in choosing the appropriate revascularization technique to treat patients with severe ischemic heart failure.

Pre-hospital fibrinolysis followed by angioplasty or primary angioplasty in acute myocardial infarction: the long-term clinical outcome.

BACKGROUND: Randomized trials comparing primary angioplasty and in-hospital fibrinolysis in acute myocardial infarction (AMI) have shown an advantage for primary angioplasty. The long-term follow-up of pre-hospital fibrinolysis followed by elective or rescue coronary angioplasty versus primary angioplasty is not well established after acute myocardial infarction. This study sought to assess the long-term clinical outcome of patients with AMI having either received pre-hospital fibrinolysis optimized by coronary angioplasty or primary angioplasty. METHODS: We conducted a retrospective analysis involving 318 patients who either underwent primary angioplasty ( n = 157) or received pre-hospital fibrinolysis followed by an angioplasty (rescue or elective) ( n = 161) within 6 hours of the onset of chest pain. RESULTS: The groups were similar regarding their baseline characteristics except for the ages. No difference was noted for in-hospital mortality (primary PTCA group: 2.48%, combined group: 2.54%; p = ns) with no increased risk of hemorrhage. The 3-year mortality was not significantly different in the two groups (9.7% vs. 4.9%; p = 0.15). Regarding major adverse cardiac events (29.5% vs. 37.5%; p = 0.23), reintervention (22.5% vs. 23.2%; p = 0.99) or target lesion revascularization (16.1% vs. 14.7%; p = 0.68), the groups were statistically similar. CONCLUSION: These data from real-life practice emphasize the safety and similar benefits on the long-term clinical outcome of AMI patients having undergone either pre-hospital fibrinolysis followed by angioplasty or primary angioplasty.

[Revascularization of acute myocardial infarction. Doing better and doing more]. / Revascularisation de l'infarctus du myocarde aigu. Faire mieux et faire plus.

Effectiveness, safety, moderation, complementary, network, consensus, strategy and evaluation are the key words in the therapeutic management of acute myocardial infarction. They focus the development of pharmacological and interventional tools of recanalisation, and the decisions for those who use them. In order to cover a condition for which the patient and doctor alike choose neither time nor place, they lead to linking methods and disciplines together for a united approach. They take account of practice in order to adapt scientific data to the realities of exercise, to justify the given means, and to propose clear, realistic and useful management guidelines to first contact doctors. They deliver the best to the greatest number of patients.
