Poor oral health has been linked to coronary heart disease (CHD). Clustering clinical oral conditions routinely recorded in adults may identify their CHD risk profile. Participants from the Paris Prospective Study 3 received, between 2008 and 2012, a baseline routine full-mouth clinical examination and an extensive physical examination and were thereafter followed up every 2 y until September 2020. Three axes defined oral health conditions: 1) healthy, missing, filled, and decayed teeth; 2) masticatory capacity denoted by functional masticatory units; and 3) gingival inflammation and dental plaque. Hierarchical cluster analysis was performed with multivariate Cox proportional hazards regression models and adjusted for age, sex, smoking, body mass index, education, deprivation (EPICES score; Evaluation of Deprivation and Inequalities in Health Examination Centres), hypertension, type 2 diabetes, LDL and HDL serum cholesterol (low- and high-density lipoprotein), triglycerides, lipid-lowering medications, NT-proBNP and IL-6 serum level. A sample of 5,294 participants (age, 50 to 75 y; 37.10% women) were included in the study. Cluster analysis identified 3,688 (69.66%) participants with optimal oral health and preserved masticatory capacity (cluster 1), 1,356 (25.61%) with moderate oral health and moderately impaired masticatory capacity (cluster 2), and 250 (4.72%) with poor oral health and severely impaired masticatory capacity (cluster 3). After a median follow-up of 8.32 y (interquartile range, 8.00 to 10.05), 128 nonfatal incident CHD events occurred. As compared with cluster 1, the risk of CHD progressively increased from cluster 2 (hazard ratio, 1.45; 95% CI, 0.98 to 2.15) to cluster 3 (hazard ratio, 2.47; 95% CI, 1.34 to 4.57; P < 0.05 for trend). To conclude, middle-aged individuals with poor oral health and severely impaired masticatory capacity have more than twice the risk of incident CHD than those with optimal oral health and preserved masticatory capacity (ClinicalTrials.gov NCT00741728).

Assess the feasibility and benefit of a health educational program on global metabolic status in prediabetic deprived subjects.Case control study.693 subjects (466 men, 227 women), aged 16 to 95 years with prediabetes and low socioeconomic status, consulting at the IPC Center were included between September 2015 and June 2016. Subjects were invited to participate in 4 workshops (2 nutrition, 2 physical activities). One year after their inclusion (visit 1), they were offered a second health check-up (visit 2). Participants were classified into 3 groups: 1) Intervention group (INTG, N=133): complete process 2) Control group (CG, N=415): Only a second health check-up, no workshop participation; 3) Abandoned group (AG, N=145). All groups were compared.After considered confounding factors, fasting blood glucose and SBP levels variation between visit 1 and visit 2 differed significantly between the CG and INTG. In the INTG with higher diminution of fasting glucose, 90% reported eating healthy food since nutrition workshop and 51%. reached objectives (The same trend was observed for physical activity.An educational program among deprived prediabetic tended to limit fasting glucose increment, improve metabolic status and encourage healthy lifestyle despite difficulties in convincing subjects to participate.

Aims The EURO-ENDO registry aimed to study the management and outcomes of patients with infective endocarditis (IE). Methods and results Prospective cohort of 3116 adult patients (2470 from Europe, 646 from non-ESC countries), admitted to 156 hospitals in 40 countries between January 2016 and March 2018 with a diagnosis of IE based on ESC 2015 diagnostic criteria. Clinical, biological, microbiological, and imaging [echocardiography, computed tomography (CT) scan, 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT)] data were collected. Infective endocarditis was native (NVE) in 1764 (56.6%) patients, prosthetic (PVIE) in 939 (30.1%), and device-related (CDRIE) in 308 (9.9%). Infective endocarditis was community-acquired in 2046 (65.66%) patients. Microorganisms involved were staphylococci in 1085 (44.1%) patients, oral streptococci in 304 (12.3%), enterococci in 390 (15.8%), and Streptococcus gallolyticus in 162 (6.6%). 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed in 518 (16.6%) patients and presented with cardiac uptake (major criterion) in 222 (42.9%) patients, with a better sensitivity in PVIE (66.8%) than in NVE (28.0%) and CDRIE (16.3%). Embolic events occurred in 20.6% of patients, and were significantly associated with tricuspid or pulmonary IE, presence of a vegetation and Staphylococcus aureus IE. According to ESC guidelines, cardiac surgery was indicated in 2160 (69.3%) patients, but finally performed in only 1596 (73.9%) of them. In-hospital death occurred in 532 (17.1%) patients and was more frequent in PVIE. Independent predictors of mortality were Charlson index, creatinine > 2 mg/dL, congestive heart failure, vegetation length > 10 mm, cerebral complications, abscess, and failure to undertake surgery when indicated. Conclusion Infective endocarditis is still a life-threatening disease with frequent lethal outcome despite profound changes in its clinical, microbiological, imaging, and therapeutic profiles.

AIMS: To examine the relationships between glycated haemoglobin (HbA1c) and cardiovascular (CV) events in people beginning insulin in routine clinical practice in Europe, North America and Asia in a non-interventional study, the Cardiovascular Risk Evaluation in people with Type 2 Diabetes on Insulin Therapy (CREDIT) study. METHODS: Data on 2999 people were collected prospectively over 4 years from physician reports. The primary outcome was the composite of stroke or myocardial infarction (MI) or CV-specific death. Events were blindly adjudicated. The relative hazards of CV events were described from Cox proportional hazards models incorporating patient risk factors, with updated average HbA1c as a time-dependent covariate. The relationship of severe and symptomatic hypoglycaemia (collected during the 6 months before yearly ascertainment) with CV and all-cause mortality was examined. RESULTS: A total of 147 primary events were accrued during up to 54 months of follow-up. In all, 60 CV-specific deaths, 44 non-fatal MIs and 57 non-fatal strokes occurred, totalling 161 events. There was a significant positive relationship between updated mean HbA1c and primary outcome: hazard ratio (HR) 1.25 [95% confidence interval (CI) 1.12-1.40; p

Aim: To use baseline characteristics of the Cardiovascular Risk Evaluation in people with type 2 Diabetes on Insulin Therapy study population to identify factors that could explain the choice of insulin therapy when beginning insulin. Methods: The source, non-interventional, longitudinal, long-term study involves 314 centres in 12 countries in five regions. People were enrolled having started any insulin regimen in the previous 12 months. To identify factors associated with the choice of insulin regimen, multivariable backward logistic regression was performed on eligible physician and participant explanatory variables. Results: Participants (N = 3031) had mean age 62 years, diabetes duration 11 years, body mass index 29.3 kg/m2 and an HbA1c of 9.5%. Participants in Japan had less hypertension, smoked more and used fewer concomitant medications than those of other regions. Only physician location (rural or urban) influenced the choice of insulin in Japan. In the other four-regions-combined, physician location, specialty, sex and practice type influenced choice of insulin as did participant location, baseline HbA1c, use of glucose-lowering therapies and prior insulin secretagogue use. Conclusion: Choice of initial insulin regimen was influenced by several physician and participant characteristics in Canada and Europe, but only by physician location in Japan.

Summary. Background: Platelet activation by antistreptokinase (SK) antibodies could impair the clinical effect of SK administration. Objective: To better describe anti-SK antibodies with particular emphasis on procoagulant activities as a result of platelet activation. Patients and methods: Sera were collected from 146 patients with coronary artery disease: non-SK-treated, 95 from mainland France, 31 from French Polynesia; 20 patients from mainland in year 2 after SK treatment. Serum-induced SK-dependent platelet activation resulting in procoagulant activities was assessed with washed platelets from five donors representative of the known patterns of reactivities to IgG. Results: Concentrations (2–5252 µg mL−1) and fibrinolytic neutralization titres ( 1280) were found in the expected wide range and correlated (ρ = 0.66, P

Homocysteine and vitamins B were correlated with coronary artery disease in patients undergoing diagnostic coronary angiography. 160 patients havingor =1 stenosis (G1), 55 patients having normal coronary arteries (G2) and 171 healthy volunteers (G3) were prospectively recruited. Homocysteine levels were significantly higher in patients, particularly in those with normal coronary angiograms, than in healthy subjects (13.8 +/-6.3 micromol/L in G1 (p0.0001) and 15.2 +/- 8.8 micromol/L in G2 (p0.0001) versus 10.1 +/- 3.1 micromol/L in G3). Homocysteine levels were not related to the extent of coronary artery disease. In patients with normal angiogram, vitamin B12 and folate levels were significantly higher compared with the other groups (p0.05 and p0.001, respectively) showing that vitamin B deficiency was not involved in the hyperhomocysteinemia. In conclusion, homocysteine and vitamins B levels do not contribute to discriminate for the presence of coronary artery disease in patients undergoing diagnostic coronary angiography. Homocysteine levels, however, were higher in patients referred for coronary angiography than in healthy controls.

To assess gender differences in characteristics, management, and hospital outcomes in patients participating in the French FAST-MI 2010 registry.Three thousand and seventy-nine patients hospitalised for ST-elevation (STEMI) or non-ST-elevation (NSTEMI) myocardial infarction in 213 French centres during a 1-month period at the end of 2010.Women account for 27% of the population and more frequently present with NSTEMI. They are 9 years older than men on average, although 25% of women with STEMI are less than 60 years of age. Management of STEMI is similar, after adjustment for baseline characteristics. However, fewer women are treated with primary percutaneous coronary angioplasty. In NSTEMI, although use of coronary angiography is similar, fewer women get treated with angioplasty. Most medications are used in a similar way in men and women, except thienopyridines, with fewer women receive prasugrel. After adjustment, in-hospital mortality is similar for men and women.Myocardial infarction is not specific to men: one out of four patients admitted for myocardial infarction is a woman. Initial management is rather similar for men and women, after taking into account differences in baseline characteristics. Percutaneous coronary angioplasty, however, remains less frequently used in women. In-hospital complications have become rarer and do not differ according to sex.

To evaluate incidence and determinants of arterial hypertension after 60 years.Four thousand nine hundred and forty one subjects aged 60 years or above (2505 men: 64.2±4.2 years; 2436 women: 64.8±4.3 years) were explored two times at the IPC center, Paris, between 1992 and 2007, and were normotensive at the first visit (V1): systolic BP (SBP) less than 140mmHg and diastolic BP (DBP) less than 90mmHg without treatment. The delay between the two visits was 5.8±2.2 years. At the second visit, population was analysed as normotensives and hypertensives. An age-adjusted Anova compared groups.In men, incidence of hypertension is 41.5% and 25.9% for isolated systolic hypertension. In women, incidences were 37.8% and 27.8% respectively. Baseline characteristics for V2-hypertensives showed higher SBP, DBP, BMI, heart rate, glycemia, ECG abnormalities thanV2-normotensives but they had lower physical activity. The determinants of hypertension were: SBP, age, BMI, DBP, glycemia, and lack of physical activity for this age class.From 60 years old, 6-year incidence of hypertension is about 40% and 26% for isolated systolic hypertension, this latter being higher in women. Regular physical activity is protective.

BACKGROUND The renarrowing process after successful percutaneous transluminal coronary angioplasty (PTCA) is now believed to be caused by a response-to-injury vessel wall reaction. The magnitude of this process can be assessed by the change in minimal lumen diameter (MLD) at follow-up angiography. The aim of the present study was to find independent patient-related, lesion-related, and procedure-related risk factors for this luminal narrowing process. A model that accurately predicts the amount of luminal narrowing could be an aid in patient or lesion selection for the procedure, and it could improve assessment of medium-term (6 months) prognosis. Modification or control of the identified risk factors could reduce overall restenosis rates, and it could assist in the selection of patients at risk for a large loss in lumen diameter. This population could then constitute the target population for pharmacological intervention studies. METHODS AND RESULTS Quantitative angiography was performed on 666 successfully dilated lesions at angioplasty and at 6-month follow-up. Multivariate linear regression analysis was performed to obtain variables with an independent contribution to the prediction of the absolute change in minimal lumen diameter. Diabetes mellitus, duration of angina < 2.3 months, gain in MLD at angioplasty, pre-PTCA MLD, lesion length > or = 6.8 mm, and thrombus after PTCA were independently predictive of change in MLD. Overall prediction of the model was poor, however, percentage-correct classification for a predicted change between -0.1 to -0.4 mm was approximately 10%. Lesions showing no change or regression (change > -0.1 mm) and lesions showing large progression (< or = -0.4 mm) were more predictable (correct classification, 59.5% and 49.7%, respectively). CONCLUSIONS Renarrowing after successful PTCA as determined with contrast angiography is a process that cannot be accurately predicted by simple clinical, morphological, and lesion characteristics.

Bivalirudin, with provisional GP IIb/IIIa inhibitor use allows the same protection against ischemic complications while reducing the hemorrhagic complications compared with the systematic association of a GP IIb/IIIa inhibitor plus heparin (The Randomized Evaluation in PCI Linking Angiomax to Reduced Clinical Events-2 [Replace-2]). In clinical practice, the use of heparin is not systematically associated with a GP IIb/IIIa inhibitor. That's why we studied the clinical and economic interest of bivalirudin only versus heparin (UFH) only. Opened pragmatic monocentric study carried out in 2007. We made a chronological matching: for each patient treated with bivalirudin, we included the next patient with the same clinical presentation treated with unfractionated heparin. Ninety-two patients were included (46 in each group). The need for a GP IIb/IIIa inhibitor during the PCI was not significantly different between the two groups (p=0.11). No major hemorrhagic complications were observed in the two groups. Prevalence of ecchymosis was not significantly different: 22 % in the UFH group versus 13 % in the bivalirudin group (p=0.27). The average troponin level the next day was significantly higher in the bivalirudin group (p=0,049), although the change in troponin levels before and after the procedure was similar in the two groups. The average cost by patient of anticoagulation by bivalirudin and HNF is very different, respectively 473+/-150 and 51+/-146 euro (p=0.0001). Bivalirudin can be an interesting alternative for patients with a high risk of having complications. But considering its cost this therapy must be used only for selected patients.

Drug-eluting stents (DES) are known to dramatically reduce restenosis. However, they are more expansive than bare-metal stents (BMS) and they require prolonged dual antiplatelet therapy. In France, the French Society of Cardiology and the "Haute Autorité de santé" have defined recommendations for the use of DES (restricted to patients in high-risk group). The aim of this work was to evaluate our practice (whether these recommendations were well respected or not in our center). Between November 2007 and January 2008 then November 2008 and January 2009 we evaluated all Percutaneous Coronary Interventions (PCI). Two hundred and sixteen (216) patients (mean age 65 ± 13 years, 164 (76 %) were males and, 41 (19 %) were diabetics) had a PCI for stable angina or silent ischemia (47 %), unstable angina or acute coronary syndrome (ACS) ST- (26 %), ACS ST+48 hours (24 %) or ACS ST+48 hours-1 month (3 %). Two hundred and seventy six (276) stents were used, including 35 % of DES. The recommendations were well respected in 82 % of cases. However, 27 % of BMS were implanted in patients in whom DES were indicated. The French recommendations for DES are a reference to help practitioners, but they require to be adapted to each patient, depending on clinical state and their ability to be treated with prolonged dual antiplatelet therapy.

Many patients at high cardiovascular risk still fail to achieve recommended LDL-C goals. Showing evidence of a difference between two statins at the same dose can significantly contribute to selecting the most appropriate strategy to reduce cardiovascular risk in these patients. ARIANE study was a randomized, open-label comparative study. 844 patients at high cardiovascular risk were recruited by primary care cardiologists in France. They were randomized to receive once-daily dose of 10 mg of rosuvastatin or atorvastatin. The primary objective of this study was to compare the efficacy of rosuvastatin with that of atorvastatin in achieving an LDL-C goal of1.00 g/1 at 12 weeks. High cardiovascular risk was defined by either history of cardiovascular event, or a type IIa or IIb dyslipidemia associated with more than 2 other cardiovascular risk factors or 2 risk factors and a 10-year coronary risk20% based on Framingham score. 790 patients were available for intention-to-treat analysis. At 12 weeks, LDL-C goal was reached by 211 of the 411 patients treated with rosuvastatin (51.3%) and 119 of 379 patients treated with atorvastatin (31.4%), the difference being statistically significant (p0.0001). Both treatments were well tolerated. Adverse events were equally observed in the 2 groups, one patient in the rosuvastatin group showed a CK elevation without clinical consequence. The risk profile for the patients in this study matched that which, in 2005, had led to the Afssaps lowering the LDL-C target below 1.00g/l. The doses of the two statins compared here correspond to the doses most commonly used in day-to-day clinical practice. The greater efficacy of rosuvastatin versus atorvastatin at the same dose demonstrated here confirms previous data. Therefore, in high risk patients treated by primary care cardiologists, rosuvastatin allows a significantly greater proportion to reach the LDL-C goal of1.00 g/l compared to atorvastatin at the same dose. However, many patients remain not at goal.

Elevated plasma homocysteine is a risk factor for coronary artery disease (CAD) and thromboembolic disorders that seems also to be associated with chronic heart failure.To evaluate the association between homocysteine and left ventricular dysfunction and to assess whether it is independent of CAD.A prospective study evaluated this relationship in 709 patients referred for diagnostic coronary angiography, including 515 CAD and 194 patients without evidence of coronary artery lesions.The homocysteine level was significantly higher in the 187 patients with a left ventricular ejection fraction (LVEF) dysfunction40% (P0.0001) than in those without ventricular dysfunction. LVEF, NYHA functional class II or III and CAD, stable angina and hypertension were clinical characteristics that influenced total homocysteine level in univariate analysis. Homocysteine was significantly associated with LVEF and N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) in univariate regression (r = -0.267, 95% CI -0.33 to -0.19, P0.0001, and r = 0.381, 95% CI 0.28-0.47, P0.0001, respectively) and in multiple regression (P = 0.0022 and P = 0.0001, respectively). Other determinants were creatinine and vitamin B(12), but not folate. LVEF was a predictor of homocysteine15 micromol L(-1) in the whole population (P for trendor = 0.0001) and in patients without documented CAD (P for trend = 0.0058).Our results showed an association of homocysteine with left ventricular systolic dysfunction and NT-pro-BNP that existed independently of documented CAD. Whether this association reflects a causative factor or a consequence of CHF and influences the prognosis of the disease remains an open question.

To evaluate the therapeutic management of cardiac failure after myocardial infarction (MI) in French intensive cardiac care units (USIC) in 2005.French cross-sectional observational study conducted in USIC of University Hospital Centres (CHU), General Hospital Centres (CHG), and private clinics. Included patients were hospitalized for MI, with a systolic ejection fractionor =40% and "having" or "having had" signs of acute heart failure during the hospitalization or diabetes.Overall, 59 sites, including 10 CHU (16.9%), 37 CHG (62.7%), and 12 private clinics (20.3%) included 447 patients. The majority of patients were male (64.9%),or =70 years (62.7%), hypertensive (53.5%) and diabetic (40.8%). They presented a class II (22.3%), class III (29.5%) and class IV (38.9%) cardiac failure severity according to NYHA classification and 20.4% had a creatinine clearance30 ml/min. The most prescribed treatments were statines (75.4%), IEC (73.6%), diuretics (71.8%) and betablockers (66.7%). The least prescribed were aldosterone antagonist (16.3%) and calcium channel blockers (6.5%). Treatments were prescribed according to age, degree of cardiac failure and renal function of the patient.The present observational study shows improved compliance with European and international guidelines, as regards the medications prescribed at hospital discharge after myocardial infarctions complicated with left ventricular dysfunction. Unfortunately, recommended medications remained less often prescribed in the patients with the most severe characteristics.

The interaction between the use of percutaneous coronary intervention (PCI) for non-ST-elevation acute coronary syndromes and the use of secondary prevention medications was analysed in the French S-Témoin Registry.The population consisted of 2433 patients seen by their cardiologists at an outpatient clinic 2-12 months after non ST-elevation ACS; the survey was carried out from September 2004 to April 2005.Overall, patients undergoing PCI (75% of the population) had higher levels of prescription of recommended secondary prevention medications. Multivariate logistic regression analysis showed that the use and type of coronary intervention (drug eluting versus bare metal stents) was an independent correlate of the use of dual antiplatelet therapy. In addition, time from the acute episode was also a strong correlate of dual antiplatelet therapy. Statins were also more often used in patients with PCI.Patients not treated with PCI are less likely to receive appropriate secondary prevention medications after non ST-elevation acute coronary syndromes. Specific efforts should be directed towards these patients, in particular as regards the prescription of dual antiplatelet therapy.

To compare processes of care for acute myocardial infarction among patients admitted to alpine vs other French hospitals.Prospective observational study of patients with ST-elevation and non ST-elevation myocardial infarction of less than 48 hours hospitalized in 369 intensive care units in November 2000.Fifty-five patients were enrolled in nine alpine hospitals and 2265 patients in 360 other French hospitals. Patients baseline characteristics did not differ between the two groups with the exception of ST-elevation myocardial infarction which was less frequent in patients admitted to alpine hospitals (71 vs. 83%, P = 0.02). Patients living in the alpine area were less likely to be admitted to hospitals with on-site cardiac catheterization facilities (42 vs. 60%, P0.01) although the use of primary (20%) and rescue (24%) percutaneous coronary intervention did not differ significantly between the two groups. There were no differences in the use of medical treatments between the two groups with the exception of low-molecular-weight heparin. The risk of in-hospital death and complications did not differ significantly between the two groups while the risk of death at one year was lower in patients admitted to alpine hospitals (5 vs. 16%, P = 0.04).In 2000, a lower proportion of patients living in the alpine area had access to hospitals with cardiac catheterization facilities compared to other French patients. This finding supports the creation of an additional cardiac catheterization laboratory with experienced operators performing percutaneous coronary interventions 24 hours/7 days and the implementation of an emergency medical care network for acute coronary syndromes in the alpine area.

A pharmacoepidemiological cross-sectional observational study was performed among a representative sample of French general practitioners and cardiologists. The aim of this study was to describe the prescription modalities of flecainide acetate, an Ic class antiarrhythmic, and how these modalities match the marketing authorization and the current summary of product characteristics. A total of 941 physicians participated in the study, 496 GPs and 445 cardiologists, and 1116 patients treated with flecainide for more than one month were included. On average, the patients were 68.7-years-old and 54% of them were women. Most of the initial flecainide prescriptions came from cardiologists (96%) and the check-up included an electrocardiogram (98%), a Holter monitoring (56%) and/or an echocardiography (71%). The preferred indication was supraventricular rhythm disorders (95%) and mostly atrial fibrillation (63%). A small proportion of coronary patients (7%) and of patient suffering from cardiac insufficiency (4%) was found. Flecainide was prescribed with a median posology of 150 mg per day, mostly as LP form (64%). Overall, the indications specified in the summary of product characteristics were respected in 90% of the cases, the contraindications in 91% of the cases and the patient follow-up was appropriate in 99% of the cases. In conclusion, the study showed that the prescription's conditions of flecainide in France complied with the summary of product characteristics data for most of the prescribing physicians with a respect of the indications, contraindications and management recommendations in 84% of the cases.

Little information is available as regards risk factor control and use of secondary prevention medications in elderly populations with documented atherosclerotic disease. The ELIAGE-MG survey included 3247 patients with cardiovascular disease seen in ambulatory practice. Overall, both the control of risk factors and the use of secondary prevention medications was suboptimal in these patients. However, those having consulted a cardiologist at any time during the previous year had better control of risk factors (and particularly LDL cholesterol and smoking) and were more often prescribed recommended secondary prevention medications.

The in-hospital management and short- and long-term outcomes was assessed in 2 registries of consecutive patients admitted for acute myocardial infarction, 5 years apart, in France. The 2000 cohort was younger and with a less frequent history of cardiac diseases, but was more often diabetic and with anterior infarcts. Time to admission was actually longer in 2000 than in 1995 (median 5.25 hours vs 4.00 hours). Overall, reperfusion therapy was used in 43% of the patients in both registries. However, the use of reperfusion therapy increased from 1995 to 2000 in patients admitted within 6 hours of symptom onset (64 vs 58%), with an increasing use of primary angioplasty (from 12 to 30%). Five-day mortality significantly improved from 7.7 to 6.1% (p0.03) and one-year survival was also less in the most recent period (85 vs 81%, p0.01). Multivariate analyses showed that the period of inclusion (2000 vs 1995) was an independent predictor of both short- and long-term mortality in patients admitted within 6 hours of symptom onset. Thus, in the real world setting, a continued decline in one-year mortality was observed in patients admitted to intensive care units for recent acute myocardial infarction, especially for patients admitted early. This goes along with a shift in reperfusion therapy towards a broader use of primary angioplasty, and with an increased use of the early prescription of recognised secondary prevention medications.

Pre-hospital management of chest pain is a difficult problem. The emergency doctor has to take triage decisions based on instantaneous data whereas the decisional rationale of the many pathologies concerned, including acute coronary syndromes, is often based on observation over several hours. There have been few studies of the efficacy of pre-hospital management of chest pain by an emergency ambulance service. Therefore, the DOLORES register was set up to assess this problem over a 6 month period by the emergency ambulance service of Necker Hospital in Paris. Between January and June 2004, the Necker emergency ambulance service was called out on 205 occasions for chest pain. Forty-three patients had acute coronary syndromes (ACS) with ST elevation. Of the remaining 162 patients, 32 stayed at home, 2 were admitted the following day by cardiologists for coronary angiography, 52 were admitted for observation to the emergency unit and 76 were admitted to the coronary care unit. In the latter two groups, the final diagnosis of ACS without ST elevation was retained in 11/52 and 57/76 patients respectively. Finally, 2 patients were admitted directly to the catheter laboratory. The clinical and paraclinical data noted by the emergency ambulance service and at hospital admission was concordant in all cases. Pre-hospital triage by the emergency ambulance service seems to be effective. These results require confirmation with a large scale study.

Several studies underlined the worse prognosis of myocardial infarction (MI) among patients with peripheral arterial disease (PAD). We sought to describe the presentation and management modalities of a cohort of PAD patients presenting an acute MI, compared to those without PAD.The USIC 2000 registry, a nationwide database on all patients admitted to a CCU for an acute MI48 hours in France in November 2000 was used for this study.Among the 2311 patients included, PAD was reported in 215 subjects (9.3%). In multivariate analysis, the following factors were positively related to the presence of PAD (Por = 0.05): age75 y (OR = 2.3), diabetes (OR = 2.0), hypertension (OR = 1.4), active smoking (OR = 4.6), renal failure (OR =3.1), and treatments with antiplatelets (OR = 3.9), anti-vitamin K (OR = 1.9), statins (OR = 1.7) and low molecular weight heparins (OR = 6.8). By introducing the data concerning the arrival in CCUs in the model, the following factors were also significantly more frequent among PAD patients: male sex (OR = 1.6), past history of coronary artery disease (OR = 2.2), left bundle branch block (OR = 1.8) and late management6 hours (OR = 1.4). Conversely, ST-segment elevation was less frequent (OR = 0.7). When the CCU stay data were introduced in the model, a lower rate of coronary stenting (OR = 0.7) and betablockers use within 48 hours of admission (OR = 0.6) were noted.Beyond the presence of PAD per se, several particularities do exist, especially the coexistence of a high number of pejorative factors and an under-utilization of treatments presenting prognostic benefits.

A large proportion of patients with a ST-elevation acute coronary syndrome do not receive reperfusion therapy. In order to contribute to a better understanding of the clinical decision making process, we analyzed which factors are associated with the application of reperfusion therapy.From the Euro Heart Survey of Acute Coronary Syndromes I, 4,260 patients with ST-elevation acute coronary syndrome were selected for the current analysis, of which 1,539 (36%) patients received fibrinolysis and 904 (21%) primary percutaneous coronary intervention (PCI). The analysis contained 32 variables on demographics, medical history, admission parameters and reperfusion therapy.A short pre-hospital delay, arrival in a hospital with PCI facilities, severe ST-elevation, and participation in a clinical trial were the strongest predictors for receiving reperfusion therapy. Primary PCI was more likely to be performed than fibrinolysis in patients with a long pre-hospital delay, arriving in a hospital with PCI facilities, not participating in a clinical trial, and with at least one previous PCI.Hospital facilities and culture, pre-hospital delay and infarction size play a major role in management decisions regarding reperfusion therapy in ST-elevation acute coronary syndrome. This analysis indicates which factors require special attention when implementing and reviewing the reperfusion guidelines.

The ANCOR survey was designed to assess the evolution of the prescription of secondary prevention medications in patients undergoing myocardial revascularisation, from the preoperative period to 3-6 months post-procedure. A total of 1535 patients (mean age: 64 years, 79% men), 321 after coronary surgery and 1214 after percutaneous coronary intervention, were included. Of them 37% still described anginal symptoms (Canadian class 1 in 80% of them); 38% still had elevated blood pressure (or = 140 mm HG systolic and/oror = 90 mmHg diastolic) and 27% of previous smokers still smoked after the procedure. All classes of secondary prevention medications were more often prescribed after than before intervention, antiplatelet agents (63.5 to 89%), beta-blockers (53 to 73.5%), statins (51 to 3%), ACE inhibitors (27 to 39%) and nicorandil (14 to 21%). Factors associated with the prescription of the different classes of medications were both expected (such as hypertension for ACE inhibitors or statins in hyperlipidemic patients) or unsupported by scientific evidence (less beta-blockers in diabetic patients). Overall this survey shows that myocardial revascularisation constitutes a key point in the management of patients with coronary disease, and that cardiologists consider that treatment of the atherosclerotic process is as important as the treatment of focal coronary artery stenoses.

More and more elderly people are hospitalised with myocardial infarction. Little is known on their pre-hospital management. In 2001 and 2002, 105 patients aged 80 years or more with suspected ST elevation infarction were managed by the mobile intensive care unit system of the SAMU de Paris-Necker. Diagnosis of infarction was confirmed in 92 (88%). Over 60% of the patients were women. Median time delay from symptom onset to call to the emergency service was 127 minutes, longer in nonagenarians (175 vs 101 minutes). Prehospital use of aspirin was 81% and 39% received an intravenous bolus of heparin. A reperfusion strategy was decided in only 30% (primary PCI: 23/26). One-month mortality was 21% and was related to older age, time when the call to the Samu was made, and absence of current smoking. Overall, the prehospital management of very elderly patients with suspected ST elevation infarction appears far from optimal.

Limited data are available regarding drug prescription for cardiovascular prevention in elderly patients seen by cardiologists.The ELIAGE survey was conducted in France between March and September 2003 among 507 cardiologists. 1952 consecutives elderly patients (or = 70 years old) were enrolled. Mean age was 76 years, 40% were between 70 and 74, and 26% were more than 80. Sixty-two of patients were men. Sixteen percent of patients had no history of cardiovascular disease but presented at least one of major cardiovascular risk factor: hypertension (91%), hyperlipemia (58%), diabetes (28%), and/or smoking (6%). Eighty-four percent had a known history of occlusive, atherosclerotic vascular disease: coronary heart disease in 76%, peripheral artery disease in 17%, and prior stroke or transient ischemic attack in 13%. Heart failure was observed in 21%.The rates of prescription in the overall survey population were respectively 68% for antiplatelet agents, 67% for lipid lowering drugs (of which 85% were on a statin), 51% for beta-blockers and 41% for angiotensin converting enzyme inhibitors. Among patients with coronary heart disease, prescription rates were 42% for ACE-inhibitors, 58% for beta-blockers, 76% for antiplatelet agents and 72% for lipid-lowering agents, 85% of whom received a statin. The ELIAGE survey shows a high prevalence of persistent dyslipidemia, with 46% of patients having a LDL-cholesterol equal to or greater than 1.25 g/l and 15%or = 1.60 g/l. Despite lipid-lowering therapy, LDL-cholesterol remained equal to or greater than 1.25 g/l in 40% of treated patients andor = 1.60 g/l in 13%. Blood pressure control was not better with 61% of patients having systolic blood pressureor = 140 mmHg and 21%or = 160 mmHg. In multivariate analysis, increase was inversely associated with the prescription of lipid-lowering therapy.The ELIAGE survey in France shows the persistence of poor control of modifiable risk factors among elderly patients seen by cardiologists. Both primary and secondary cardiovascular prevention appear to be unsatisfactory. Improved utilisation of proven therapeutic classes may lead to improvements in cardiovascular prevention.

We assessed the in-hospital management and short- and long-term outcomes of two series of patients admitted for acute myocardial infarction, 5 years apart, in France. The most recent cohort was younger and with a less frequent history of cardiac diseases, but was more often diabetic and with anterior infarcts. Five-day mortality significantly improved from 7.7% to 6.1% (P0.03) and 1-year survival was also less in the most recent period (15% versus 19%, P0.01). Multivariate analyses showed that the period of inclusion (2000 versus 1995) was an independent predictor of both short- and long-term mortality. In analyses restricted to the patients who were alive by day 5, initial treatment with statins was associated with a 38% decrease in the risk of death at 1 year. Likewise, in patients with left ventricular ejection fractionor = 35%, the early prescription of ACE inhibitors was associated with a 41% reduction in the risk of 1-year mortality. Thus, in the real world setting, a continued decline in 1-year mortality is observed in patients admitted to intensive care units for recent acute myocardial infarction. This goes along with a shift in reperfusion therapy towards a broader use of coronary angioplasty and with an increased use of the early prescription of recognised secondary prevention medications.

A recent meta-analysis of all randomised trials assessing the efficacy and safety of glycoprotein IIb/IIIa agents with acute coronary syndromes showed that there was a significant interaction with sex. Explaining this difference requires an analysis of whether it has any pathophysiological basis, whether antithrombotic medications are indeed less efficacious in women in different clinical situations, and whether there are any specific reasons that may have led to the provocative results of the meta-analysis.

To compare the results of two readings of Intima Media thickness (EIM): one performed during measurement by the cardiologist, the other by a technician in a reading unit. To evaluate the consequences of these readings on the principal criterion of a study conducted into cardiovascular risk (RCV) for hypertensives followed up in ordinary medical practice.The EIM was measured in 991 hypertensives with the aid of the M'Ath program by cardiologists specially trained in the technique, within the framework of a study aimed at evaluating the RCV according to the WHO/ISH classification. The re-reading of source data by a reference centre was performed with the same program.The analysis was performed in 973 patients after eliminating duplicates and missing values (2%). The average cardiologist value of EIM was 0.761 +/- 0.168 mm, after centralised reading it was 0.743 +/- 0.128 mm. The difference between the measurements was -0.020 +/- 0.150 (p0.0001). According to the OMS/ISH classification, the presence of a vascular condition categorizes a hypertensive as being at "high risk" of a cardiovascular complication occurring. The calculation of RCV was performed by taking a value of EIM0.7 mm and/or presence of a plaque to define a vascular condition. The appreciation of risk was identical for the subjects at low risk and at very high risk. There was a shift from medium risk towards high risk: General Medicine 15%, Cardio 49%, after re-reading 68%.Despite the simplicity and the good inter observer reproducibility of the measurement of EIM by the M'Ath program, centralization of the reading is recommended during clinical trials.

Ticlopidine or clopidogrel combined with aspirin decrease major cardiac events (Mace) after PTCA with stent implantation. It has not be proven yet that pretreatment by T or C was superior to conventional post-treatment, especially in unstable patients. The aim of the present study was to determine the influence of thienopyridine pretreatment on the risk of Mace (death, Q wave myocardial infarction, need for repeat PTCA or surgery, angina recurrence, stent thrombosis) during the hospitalization period in a population prospectively included in 2 multicentre registries of patients undergoing placement of a S670 or S7 stent (Medtronic) implanted in native coronary arteries (or = 3.0 mm). Among the 2929 patients included into the registries, 1205 had unstable angina (41%). 50.2% of the patients were pretreated by T or C (T = 15.7%, C = 34.5%); 85.5% received aspirin before the procedure; definition of pretreatment was the administration of drug at least 6 hours before stent implantation. GPIIb-IIIa antagonists were administered in only 13.9% of patients. Mace were observed in 2% of the patients. Factors correlated with Mace by univariate and multivariate analyses were: age73 years (RR: 2.37; 95% CI: 1.05-5.36, P0.037), previous myocardial infarction (RR: 2.56; 95% CI: 1.08-6.11, P0.034), pretreatment by T or C (RR: 0.389; 95% CI: 0.16-0.95, P0.038). In patients who did not receive GPIIb-IIIa antagonists, age73, and pretreatment by T or C were the only independent predictors of Mace.

The use of cardiovascular secondary prevention medications in patients with acute coronary syndromes was compared in 4 sequential observational surveys carried out in France from 1995 to 2000. The Usik 1995 and Usic 2000 surveys included patients admitted for acute myocardial infarction, while the 2 Prevenir surveys (1998 and 1999) assessed the medications prescribed in patients with acute coronary syndromes. Antiplatelet agents were prescribed in 91% of the patients in 1995, 93% in 1998 and 1999 and 96% in 2000; for beta-blockers, the respective figures were: 64%, 68%, 75% and 76%. For ACE-Inhibitors, the figures were: 46%, 41%, 41% and 50%. For statins, the prescription increased from 10% to 36%, 59% and 64%. In 1995, 8% of the patients received both antiplatelet agents, beta-blockers and statins (4% of them also had an ACE-Inhibitor); in 2000, the respective figures were 53% and 27%. The results of the recent trials of secondary prevention medications have had a considerable impact on real-life practice in France during the late 1990s.

Three cases reports illustrate the concept of beating heart cardiac surgery and its advantages regarding the prevention of arterial emboli.

Of 2,626 patients admitted for acute coronary syndromes and participating in the PREVENIR 1 and 2 registries, 202 (8%) were aged less than 45 years. Younger patients were more often smokers (79% versus 37%), but systemic hypertension and diabetes were less frequent. Reperfusion therapy was more frequently used in the younger patients (63% versus 46%). At hospital discharge, aspirin and angiotensin converting enzyme inhibitors were prescribed as often in younger and older patients. In contrast, beta-blocking agents and statins were used more often in the younger patients. More younger patients participated in a cardiac rehabilitation programme. Left ventricular ejection fraction was less altered in the younger age group and none of the younger patients died between hospital discharge and six months follow-up.

The role of early reperfusion therapy at the acute stage of myocardial infarctus in elderly patients is debated. The aim of this study was to analyze the prognostic role of reperfusion with i.v. thrombolysis or primary PTCA in the nationwide USIK database, which prospectively included all pts admitted to a CCU for an AMI48 hours in France in November 1998. For the purpose of the present study, only patients admitted within 24 hours of AMI and with one-year follow-up available were included. Of the 1838 patients included, 785 were70 years-old, of whom 225 (29%) had early reperfusion therapy with thrombolysis (N = 173) or primary PTCA (N = 52). Patients treated with early reperfusion had a baseline profile that differed substantially from that of patients treated conventionally: women (31% vs 50%, p0.001), admission within six hours of symptom onset (84% vs 55%, p0.001), history of systemic hypertension (48% vs 60%, p0.002), stroke (5% vs 11%, p0.01), peripheral arterial disease (8% vs 18%, p0.001); congestive heart failure (5% vs 20%, p0.001) or previous MI (12% vs 25%, p0.001), more anterior location of current MI (40% vs 28%, p0.002). Overall one-year Kaplan-Meier survival was 78% for patients with versus 64% for those without reperfusion therapy (p0.01). In patients with Q wave myocardial infarction, Cox multivariate analysis showed that reperfusion therapy was an independent predictor of survival (RR 0.66; 95% Confidence Interval: 0.45-0.96), along with age, anterior location and history of congestive heart failure. Therefore, data from this large "real life" registry indicate that reperfusion therapy with either thrombolysis or primary PTCA is associated with improved one-year survival in patients over 70 years of age.

The difficulty in controlling hypertension in coronary patients has been underlined. The aim of the study was to assess blood pressure profile (BP) at hospital discharge in a large population of survivors of an acute coronary syndrome.An observational study was conducted in France in 77 cardiological centers. The medical records of all patients admitted in these hospitals on January 1998 for a myocardial infarction or unstable angina and who survived were studied. Clinical characteristics and BP at hospital discharge were recorded. Patients with blood pressureor = 140/90 mmHg were considered as uncontrolled hypertensives (HT).Data were available in 1327 of the 1394 patients recruited: at hospital discharge, 344 patients (25.9%) were controlled and 431 (32.4%) were uncontrolled hypertensives. Among these patients, 406 (94.1%) had systolic blood pressureor = 140 mmHg, 139 (32.2%) had diastolic blood pressureor = 90 mmHg and 292 patients (67.7%) had systolic blood pressureor = 140 mmHg and diastolic blood pressure90 mmHg. Pulse pressure in controlled hypertensives (51.02 +/- 10.93 mmHg) was quite similar to that in normotensives (47.81 +/- 9.84 mmHg) whereas pulse pressure was significantly higher in uncontrolled hypertensives (65.86 +/- 13.29 mmHg).At hospital discharge after a coronary event, arterial hypertension is uncontrolled in 32.4% of patients mainly because of poor systolic blood pressure control. Achieving normal blood pressure throughout the hospitalisation should improve long term blood pressure control, reduce pulse pressure and improve the prognosis in this high risk population.

The aim of this study was to evaluate the distribution and hospital treatment of cardiovascular risk factors in coronary patients. A transverse observational study was carried out in 77 cardiological centres throughout France. All patients with a history of myocardial infarction or of unstable angina during the month of January 1998 were enrolled. The clinical features of 1334 patients (71.4% men, 746 myocardial infarction, 588 unstable angina) on hospital admission were analysed. The prevalence of smoking, dyslipidaemia, hypertension and obesity was 49, 45, 42, 19 and 11% respectively in the men and 17, 46, 63, 23 and 10% respectively in the women. The number of treatable risk factors slightly decreased in the oldest age group. The prevalence of hypertension increased with age whereas smoking and dyslipidaemia decreased in both men and women. Obese and diabetic patients had more risk factors than the others. A little less than half of patients with dyslipidaemia were under no preventive measures (diet and/or lipid-lowering drugs) and 40% of men with a previous history of coronary artery disease continued to smoke. The authors conclude that men over 85 and women over 75 years of age have fewer risk factors than other age groups and the type of risk factor varies with age. The treatment of dyslipidaeamia and smoking is still inadequate and should be improved.

Patients with acute myocardial infarction (AMI) who do not receive early reperfusion therapy are at high risk of reinfarction or death, and the efficacy and safety of antithrombotic therapy in this group of patients has not been evaluated. Enoxaparin is a low-molecular-weight heparin (LMWH) that has previously been shown to reduce the incidence of ischemic events in patients with unstable angina or non-Q-wave MI. The principal aims of the TETAMI study are to investigate the efficacy and safety of treatment with enoxaparin or tirofiban (a glycoprotein IIb/IIIa receptor antagonist) alone or in combination for 2 to 8 days in patients with AMI who are not eligible for early reperfusion therapy. In this 2 by 2 factorial design study approximately 900 patients will be randomly assigned, in a blinded manner, to one of four treatments: enoxaparin alone, enoxaparin plus tirofiban, unfractionated heparin (UFH), or UFH plus tirofiban, with appropriate matched placebos. The primary end point is the composite of death, recurrent AMI, and recurrent angina, analyzed at 30 days after AMI. The design and methods of the TETAMI study are described in this article.

The aim of this study was to evaluate the risks and benefits, immediate and at long term, of coronary angioplasty associated with stent implantation in patients with severe left ventricular dysfunction. It was a retrospective study in which all patients with left ventricular ejection fractions 35% who underwent angioplasty between December 1994 and January 1998 were included. Seventy eight patients with an average ejection fraction of 29 +/- 6% who were haemodynamically stable were retained, excluding acute myocardial infarctions and cases of cardiogenic shock. The population was mainly masculine (6(men and 13 women) with a mean age of 65 +/- 11 years. The primary success rate was 97%. The loss of a collateral branch during the procedure, causing a non-Q wave infarction and the impossibility of implanting the stent at the desired site in another patient, were the only two failures. Hospital mortality was nil. The mean follow-up period was 450 +/- 290 days; long-term mortality was 17%. All deaths were of cardiovascular origin. The probability of survival at 6 months, 1 year and 800 days, was 88, 85 and 75% respectively. The good initial results were not maintained at long-term, but this could not be attributed to restenosis or to the pre-existing left ventricular dysfunction.

The transmembrane sodium/hydrogen exchanger maintains myocardial cell pH integrity during myocardial ischemia but paradoxically may precipitate cell necrosis. The development of cariporide, a potent and specific inhibitor of the exchanger, prompted this investigation of the potential of the drug to prevent myocardial cell necrosis.A total of 11 590 patients with unstable angina or non-ST-elevation myocardial infarction (MI) or undergoing high-risk percutaneous or surgical revascularization were randomized to receive placebo or 1 of 3 doses of cariporide for the period of risk. The trial failed to document benefit of cariporide over placebo on the primary end point of death or MI assessed after 36 days. Doses of 20 and 80 mg every 8 hours had no effect, whereas a dose of 120 mg was associated with a 10% risk reduction (98% CI 5.5% to 23.4%, P=0.12). With this dose, benefit was limited to patients undergoing bypass surgery (risk reduction 25%, 95% CI 3.1% to 41.5%, P=0.03) and was maintained after 6 months. No effect was seen on mortality. The rate of Q-wave MI was reduced by 32% across all entry diagnostic groups (2.6% versus 1.8%, P=0.03), but the rate of non-Q-wave MI was reduced only in patients undergoing surgery (7.1% versus 3.8%, P=0.005). There were no increases in clinically serious adverse events.No significant benefit of cariporide could be demonstrated across a wide range of clinical situations of risk. The trial documented safety of the drug and suggested that a high degree of inhibition of the exchanger could prevent cell necrosis in settings of ischemia-reperfusion.

The predictive value of several diagnostic strategies after myocardial infarction was assessed in 178 patients (mean age 55 +/- 9 years) treated medically after a primary Q wave myocardial infarction. Within 6 weeks of onset of symptoms the authors performed exercise stress test coupled with Thallium 201 scintigraphy, isotopic left ventriculography and conventional coronary angiography with ventriculography. The average left ventricular ejection fraction was 45 +/- 12%. Two non-invasive diagnostic strategies with and without results of scintigraphy and two invasive strategies with and without ventricular volumes were studied. The average follow-up period was 58 +/- 22 months. Sixteen cardiac deaths occurred. Multivariate Cox analysis showed that, in contrast to left ventricular volumes, coronary angiography did not provide additional prognostic value compared with the non-invasive model with Thallium scintigraphy and did not appear to be essential in terms of predictive value in this population. Moreover, the size of reversible defect on Thallium scintigraphy was an independent predictive factor of cardiac death and provided additional and independent prognostic information in the non-invasive and invasive strategies. Therefore, the reduction of residual ischaemia by coronary revascularisation could improve the long-term prognosis after myocardial infarction.

Sildenafil (Viagra), an inhibitor of phosphodiesterase 5, has a powerful vasodilatory effect on the corpus cavernosa. An evaluation of coronary risk is necessary before its prescription in order to answer two questions: does taking this drug expose the patient to any special risk? Does the return to sexual activity itself carry any risk? Sildenafil is associated with a slight decrease in systolic (10 mmHg) and diastolic (7 mmHg) blood pressure which does not seem to be accentuated by the concommittant use of antihypertensive drugs. The co-administration of nitrate derivatives (before or after taking sildenafil) causes potentially dangerous falls in blood pressure (on average 40 mmHg for the systolic blood pressure). Co-administration of sildenafil and NO-donors is formally contra-indicated. The safety of sildenafil has been shown to be satisfactory in clinical trials: in particular, the risk of myocardial infarction is no greater in treated patients. Sexual activity is a generally moderately intense physical exercise and only rarely causes myocardial infarction. In practice, in patients without known coronary artery disease, the clinical history should be sufficient to determine whether the return of sexual relations is possible without risk. In known cardiac patients, sildenafil is contra-indicated in unstable situations; in stable coronary disease, it would seem wise to take advantage of the annual exercise stress testing to make sure of the absence of ischaemia on effort. In all cases, the patient must be warned that co-administration of nitrate derivatives is an absolure contra-indication to sildenafil treatment.

Percutaneous transluminal coronary angioplasty (PTCA) has become the most widely used major intervention in western medicine. However, there is disparate use of this technique among different European countries and the U.S.A. In an attempt at quality assurance, the working group Coronary Circulation of the European Society of Cardiology has carried out a study on appropriateness, necessity, and performance of PTCA in Europe. The present paper reports on the procedural results of this survey.In a multicentre case-control study in Europe, 750 patients (544 men, 206 women) with documented vascular disease of the From the countries participating in the European Registry of Coronary Intervention, the three countries with the highest absolute PTCA volume (Germany, France, and the United Kingdom) and two randomly selected countries (Belgium and Italy) were chosen for investigation. In these countries, five centres were selected at random according to the following criteria: one centre with1000, three centres with 300-1000, and one centre with300 procedures per year. In each of these, 10 cases from the first half of 1997 were randomly identified and all pertinent documentation was collected.In 250 cases, 325 stenoses were addressed as target lesions. Single vessel disease was present in 41%. History included stable angina in 49%, unstable angina in 32%, atypical chest pain in 6%, no anginal pain in 12%, and acute/subacute myocardial infarction in 13%. The percentage of patients with either positive stress test and/or unstable angina, acute/subacute infarction, previous infarction (within 6 months) or coronary revascularization amounted to 98%. Single vessel intervention accounted for 90%. In 41% balloon-only angioplasty was performed and in 54% at least one stent was implanted with considerable variation among countries. The use of other new devices amounted to only 3%. In 92%, the operators documented a successful procedure. Major complications (myocardial infarction, emergency bypass surgery, or death) were found in 4.8%.Based on scrutinized hospital and operator data, the present study revealed a satisfactorily high percentage of justifiable indications, an adequate procedural success rate, and an acceptably low complication rate. Further analysis by an expert panel will address appropriateness, necessity, and procedural performance of the individual cases.

The purpose of this study was to determine whether antianginal medications modify the prognostic significance of exercise single photon emission computed tomography (SPECT) ischemia.Antianginal medications (especially beta-adrenergic blocking agents) limit exercise SPECT ischemia, but it is not known whether such medications also modify the prognostic effect of exercise SPECT ischemia.We included 352 patients with coronary heart disease, who had exercise Tl-201 SPECT and coronary angiography, and who were initially treated medically. Survival Cox models were applied in patients for whom classes of antianginal medications taken at exercise SPECT were the same as those prescribed for follow-up (GI; n = 136), and in patients for whom new classes of antianginal medications, including beta-blockers (GII; n = 79) or not including beta-blockers (GIII; n = 113), were added for follow-up.During a mean 5.3+/-1.6 years of follow-up, 45 patients had cardiac death or myocardial infarction. Variables reflecting necrosis (irreversible defect extent, left ventricular ejection fraction) and those from coronary angiography provided equivalent prognostic information in the three groups. In contrast, the SPECT variable reflecting ischemia (reversible defect extent), which provided comparable prognostic information in GI (p = 0.005) and GIII (p = 0.004), lost its prognostic significance (p = 0.54) in GII, and was associated with a lower relative risk in GII than in GI or GIII (both p0.05).In patients with coronary heart disease, the introduction of antianginal medications, when including beta-blockers, appears to have a favorable effect on the deleterious prognostic effect of exercise ischemia.

We report the case of a 59-year-old man with a dilated nonischemic cardiomyopathy who had chronic rapid atrial fibrillation despite several therapies. Radiofrequency modification of the atrioventricular (AV) junction slowed the mean ventricular rate from 120 beats per minute (bpm) to 60 bpm. Five hours after the procedure and during the following 1 week, despite ventricular pacing at 90 bpm, the patient developed nonsustained or sustained polymorphic ventricular tachycardias. Finally, pacing at 90 bpm was successfully used in this patient. In conclusion, patients who have undergone modification of AV conduction may be at high risk of life-threatening ventricular arrhythmias in the first week following the procedure.

The initial phase of the epidemiological USIK study has recensed data concerning 2,563 patients admitted to hospital for acute myocardial infarction. The second phase of this study has documented the 1 year survival of 2,152 patients (84%). The population comprised 1,533 men and 619 women with a mean age of 67 years. Severe left ventricular dysfunction (LVEF35%) was observed in 18% of patients and clinical signs of cardiac failure were present in 35% of patients in the first 5 days of infarction. The mortality was 8.2% at 5 days, 13.2% at 28 days and 19.5% at one year. In multivariate analysis, the principal predictive factor of mortality at 1 year was age (RR = 1.06, p = 0.0001): the mortality increased by 6% per year of age. In survivors 5 days after the onset of infarction, the 1 year prognosis was significantly correlated with age (RR = 1.05, p = 0.0001) and with cardiac failure (LVEF: RR = 1.57, p = 0.0001) and Killip class (RR = 1.66, p = 0.0001). The prescription of an ACE inhibitor or a betablocker in the first 5 days of infarction was associated with a reduction in 1 year mortality of 27% (p = 0.04) and 37% (p = 0.01) respectively. In conclusion, this study has determined the features of patients admitted to the Intensive Care Unit for acute myocardial infarction in France and to identify the factors influencing 1 year survival.
