[Evaluation of the ExSel® self-questionnaire to screen for an excess salt intake in patients followed in a nephrology consultation]. / Évaluation de l'autoquestionnaire ExSel® pour dépister une consommation excessive de sel chez les patients consultant en néphrologie.

AIM: To evaluate the reliability of the ExSel® self-questionnaire to detect an excess salt intake (≥12g/24h) in patients consulting for hypertension and/or renal failure. METHODS: Results of the ExSel® self-questionnaire were compared to 24h sodium excretion using the Cohen's kappa test and a Chi2 test. Sensitivity, specificity, VPP and VPN were calculated. A ROC curve was realized to find an accurate cut-off. RESULTS: Mean characteristics of the 101 patients with reliable results were: age of 67±12 years, Body Mass Index 28.4±5.6kg/m2, SBP/DBP 139±23/74±13mmHg (98% were hypertensives. Mean salt intake was 7.5±3.1g/24h and mean creatininuria was 13.9±20.1mmol/24h. An excess salt intake (≥12g/24h) was observed in 8% of the patients. The Kappa test at 0.17 and the Chi2 at 0.66 signify that the agreement was very low. Sensitivity was 37%, specificity 90%, PPV 20% and NPV 94%. The AUC under the ROC curve was too low (0.665) to determine a threshold adapted to the renal patients. CONCLUSIONS: The ExSel® autoquestionnaire is not adapted to outpatients, mainly hypertensives (98%) followed in a nephrology consultation to detect an excess salt consumption.

Management of resistant hypertension: expert consensus statement from the French Society of Hypertension, an affiliate of the French Society of Cardiology.

To improve the management of resistant hypertension, the French Society of Hypertension, an affiliate of the French Society of Cardiology, has published a set of eleven recommendations. The primary objective is to provide the most up-to-date information based on the strongest scientific rationale and that is easily applicable to daily clinical practice. Resistant hypertension is defined as uncontrolled blood pressure on office measurements and confirmed by out-of-office measurements despite a therapeutic strategy comprising appropriate lifestyle and dietary measures and the concurrent use of three antihypertensive agents including a thiazide diuretic, a renin-angiotensin system blocker (ARB or ACEI) and a calcium channel blocker, for at least 4 weeks, at optimal doses. Treatment compliance must be closely monitored, as must factors that are likely to affect treatment resistance (excessive dietary salt intake, alcohol, depression, drug interactions and vasopressor drugs). If the diagnosis of resistant hypertension is confirmed, the patient should be referred to a hypertension specialist to screen for potential target organ damage and secondary causes of hypertension. The recommended treatment regimen is a combination therapy comprising four treatment classes, including spironolactone (12.5-25 mg per day). In the event of a contraindication or a non-response to spironolactone, or if adverse effects occur, a ß-blocker, an α-blocker, or a centrally acting antihypertensive drug should be prescribed. Because renal denervation is still undergoing assessment for the treatment of hypertension, this technique should only be prescribed by a specialist hypertension clinic.

Can we identify response markers to antihypertensive drugs? First results from the IDEAL Trial.

Current antihypertensive strategies do not take into account that individual characteristics may influence the magnitude of blood pressure (BP) reduction. Guidelines promote trial-and-error approaches with many different drugs. We conducted the Identification of the Determinants of the Efficacy of Arterial blood pressure Lowering drugs (IDEAL) Trial to identify factors associated with BP responses to perindopril and indapamide. IDEAL was a cross-over, double-blind, placebo-controlled trial, involving four 4-week periods: indapamide, perindopril and two placebo. Eligible patients were untreated, hypertensive and aged 25-70 years. The main outcome was systolic BP (SBP) response to drugs. The 112 participants with good compliance had a mean age of 52. One in every three participants was a woman. In middle-aged women, the SBP reduction from drugs was -11.5 mm Hg (indapamide) and -8.3 mm Hg (perindopril). In men, the response was significantly smaller: -4.8 mm Hg (indapamide) and -4.3 (perindopril) (P for sex differences 0.001 and 0.015, respectively). SBP response to perindopril decreased by 2 mm Hg every 10 years of age in both sexes (P=0.01). The response to indapamide increased by 3 mm Hg every 10 years of age gradient in women (P=0.02). Age and sex were important determinants of BP response for antihypertensive drugs in the IDEAL population. This should be taken into account when choosing drugs a priori.

[Renal denervation for treating hypertension: experience at the University Hospital in Lyon]. / Dénervation rénale dans le traitement de l'hypertension artérielle résistante : expérience du CHU de Lyon.

AIM: We report the first experience of Lyon's university hospital regarding renal denervation to treat patients with resistant essential hypertension. PATIENTS AND METHODS: Over a one-year period, 17 patients were treated (12 men, 5 women) with renal denervation. Baseline characteristics were as follows: age 56.5±11.5 years, BMI 33±5kg/m(2) and ambulatory blood pressure 157±16/87±13mmHg with 4.2±1.5 anti-hypertensive treatment. RESULTS: We did not observe intra-operative or early complications. After a median follow-up of 3 months and with the same anti-hypertensive treatment, office systolic blood pressure (SBP) and diastolic blood pressure (DBP) decrease respectively of 20±15 (P<0.001) and 10±13mmHg (P=0.014) (n=17). After six months of follow-up, ambulatory blood pressure (ABPM) decrease of 17.5±14.9mmHg (P=0.027) for SBP and of 10.5±9.6mmHg (P=0.029) for DBP (n=6). Among these patients, five of them were controlled (ABPM inferior to 130/80mmHg) and electrical left ventricular hypertrophy indexes decreased: R wave in aVL lead of 4±3mm (P=0.031), Sokolow index of 3±3mm (P=0.205), Cornell voltage criterion of 9±7mm (P=0.027) and Cornell product of 1310±1104 (P=0.027). CONCLUSION: Our results are in accordance with data from other centers. On average blood pressure decreases significantly but important inter individual variations are observed. The procedure seems safe.

Is it useful to repeat an adrenal venous sampling in patients with primary hyperaldosteronism?

UNLABELLED: Adrenal venous sampling (AVS) is a challenging technical procedure and few patients had AVS procedure twice. AIM: To evaluate the reproducibility of the AVS, why AVS were repeated and the conclusions drawn from them. PATIENTS AND METHODS: From 1997-2012, 12 patients underwent two AVS. A cortisol level in the adrenal vein greater than or equal to 1.1 to inferior vena cava defined a successful catheterization and a lateralization of secretion corresponded to an aldosterone-to-cortisol vein ratio greater than or equal to 2 between the one side to another. RESULTS: The same side of lateralization of secretion was found in 75% of them. The second AVS were due to technical failure (n=4), unproven lateralization (n=2), a lateralization opposite to the main nodule and ipsilateral to hyperplasia (n=4) on first AVS. For two patients, as the CT was normal, AVS was required again. The second AVS was successful in all patients, including those with an initial technical failure but only patient with technical failure underwent surgery, as BP and kaliemia were controlled. Lateralization on the side of hyperplasia or opposite to the biggest nodule was confirmed in two of four cases. CONCLUSION: When AVS is unsuccessful for technical reasons, it is worth doing it again but after being sure that surgery is still possibly indicated.

[Microalbuminuria and urinary albumin excretion: French guidelines]. / Microalbuminurie et excrétion urinaire d'albumine: recommandations pour la pratique clinique.

UNLABELLED: Measurement of urinary albumin excretion (UAE) may be done on a morning urinary sample or on a 24 hour-urine sample. Values defining microalbuminuria are: - 24-hour urine sample: 30-300 mg/24 hours - Morning urine sample: 20-200 mg/mL or 30-300 mg/g creatinine or 2.5-25 mg/mmol creatinine (men) or 3.5-35 mg/mol (women). - Timed urine sample: 20-200 mug/min. The optimal use of semi-quantitative urine test-strip is not clearly defined. It is generally believed that microalbuminuria reflects a generalized impairment of the endothelium; however, no definite proof has been shown in humans. In diabetic subjects, microalbuminuria is a marker of increased risk of cardiovascular (CV) and renal morbidity and mortality in type 1 and type 2 diabetic subjects. The increase in UAE during follow-up is also a marker of CV and renal risk in type 1 and type 2 diabetic subjects; its decrease during follow-up is associated with lower risks. In non-diabetic subjects, microalbuminuria is a marker of increased risk for diabetes mellitus, deterioration of the renal function, CV morbidity and all-cause mortality. It is a marker of increased risk for the development of hypertension in normotensive subjects, and is associated with unfavorable outcome in patients with cancer and lymphoma. Persistence or elevation of UAE overtime is associated with deleterious outcome in some hypertensive subjects. Measurement of UAE may be recommended in hypertensive subjects with 1 or 2 CV risk factors in whom CV risk remains difficult to assess, and in those with refractory hypertension: microalbuminuria indicates a high CV risk and must lead to strict control of arterial pressure. Studies focused on microalbuminuria in non-diabetic, non-hypertensive subjects are limited; most of them suggest that microalbuminuria predicts CV complications and deleterious outcome as it is in diabetic or hypertensive subjects. Subjects with a history of CV or cerebrovascular disease have an even greater CV risk if microalbuminuria is present than if it is not; however, in all cases, therapeutic intervention must be aggressive regardless of whether microalbuminuria is present or not. It is not recommended to measure UAE in non-diabetic non-hypertensive subjects in the absence of history of renal disease. Monitoring of renal function (UAE, serum creatinine and estimation of GFR) is annually recommended in all subjects with microalbuminuria. MANAGEMENT: in patients with microalbuminuria, weight reduction, sodium restriction (< 6 g/day), smoking cessation, strict glucose control in diabetic subjects, strict arterial pressure control are necessary; in diabetic subjects: use of maximal doses of ACEI or ARB are recommended; ACEI/ARB and thiazides have synergistic actions on arterial pressure and reduction of UAE; in non-diabetic subjects, any of the five classes of anti-hypertensive medications (ACEI, ARB, thiazides, calcium channel blockers or beta-blockers) can be used.

Microalbuminuria and urinary albumin excretion: French clinical practice guidelines.

Urinary albumin excretion (UAE) may be assayed on a morning urinary sample or a 24 h-urine sample. Values defining microalbuminuria are: 1) 24-h urine sample: 30-300 mg/24 h; 2) morning urine sample: 20-200 mg/ml or 30-300 mg/g creatinine or 2.5-25 mg/mmol creatinine (men) or 3.5-35 mg/mmol (women); 3) timed urine sample: 20-200 mug/min. The optimal use of semi-quantitative urine test-strip is not clearly defined. It is generally believed that microalbuminuria reflects a generalized impairment of the endothelium; however, no definite proof has been obtained in humans. IN DIABETIC SUBJECTS: Microalbuminuria is a marker of increased risk of cardiovascular (CV) and renal morbidity and mortality in type 1 and type 2 diabetic subjects. The increase in UAE during follow-up is associated with greater CV and renal risks in type 1 and type 2 diabetic subjects; its decrease during follow-up is associated with lower risks. IN NON-DIABETIC SUBJECTS: Microalbuminuria is a marker of increased risk for diabetes mellitus, deterioration of renal function, CV morbidity and all-cause mortality. It is a marker of increased risk for the development of hypertension in normotensive subjects, and is associated with unfavorable outcome in patients with cancer and lymphoma. Persistence of elevated UAE during follow-up is associated with poor outcome in some hypertensive subjects. Measurement of UAE may be recommended in hypertensive medium-risk subjects with 1 or 2 CV risk factors in whom CV risk remains difficult to assess, and in those with refractory hypertension: microalbuminuria indicates a high CV risk and must lead to strict control of arterial pressure. Studies focused on microalbuminuria in non-diabetic non-hypertensive subjects are limited; most of them suggest that microalbuminuria predicts CV complications and deleterious outcome. Subjects with a history of CV or cerebrovascular disease have an even greater CV risk if microalbuminuria is present than if it is not; however, in all cases, therapeutic intervention must be aggressive regardless of whether microalbuminuria is present or not. It is not recommended to measure UAE in non-diabetic non-hypertensive subjects in the absence of history of renal disease. Monitoring of renal function (UAE, serum creatinine and estimation of GFR) is recommended annually in all subjects with microalbuminuria. MANAGEMENT: In patients with microalbuminuria, weight reduction, sodium restriction (<6 g per day), smoking cessation, strict glucose control in diabetic subjects, strict arterial pressure control are necessary; in diabetic subjects: use of maximal doses of angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) are recommended; ACEI/ARB and thiazides have synergistic actions on arterial pressure and reduction of UAE; in non-diabetic subjects, any of the five classes of anti-hypertensive medications (ACEI, ARB, thiazides, calcium channel blockers or beta-blockers) can be used.

Insulin, C-peptide and proinsulin for the biochemical diagnosis of hypoglycaemia related to endogenous hyperinsulinism.

OBJECTIVE: We evaluated the respective value of insulin, C-peptide and proinsulin levels in 33 patients with endogenous hyperinsulinism and in 67 controls to determine the best parameters and thresholds to make or to rule out the diagnosis of endogenous hyperinsulinism. RESULTS: When blood glucose levels were below 2.5 mmol/l, insulin was <21 pmol/l in 8-35% of the patients and in all controls; C-peptide was >0.2 nmol/l in all insulinomas but not in the nesidioblastosis or in the controls; proinsulin was >5 pmol/l in all patients but not in the controls. When fasting blood glucose levels reached 2.5-3.3 mmol/l, proinsulin was <22 pmol/l in all the controls and >22 pmol/l in 74% of the patients. Proinsulin after an overnight fast was below 22 pmol/l in all non-obese controls and above 22 pmol/l in 73% of non-obese patients. CONCLUSION: Proinsulin levels above 5 pmol/l with blood glucose levels below 2.5 mmol/l during a 72 h fast test represent the best criterion for the diagnosis of endogenous hyperinsulinism, reaching 100% diagnostic specificity and sensitivity. Concomitant C-peptide levels above 0.2 nmol/l also make the diagnosis of all our insulinoma patients, not the diagnosis of nesidioblastosis, while insulin levels have much less diagnostic accuracy. Whether proinsulin levels above 22 pmol/l could also make the diagnosis of endogenous hyperinsulinism in part of the patients at the time of fasting blood glucose levels between 2.5 and 3.3 mmol/l or after an overnight fast in non-obese subjects needs further study.

GH responsiveness in a large multinational cohort of SGA children with short stature (NESTEGG) is related to the exon 3 GHR polymorphism.

OBJECTIVE: The polymorphic deletion of exon 3 of the GH receptor (d3-GHR) has recently been linked to the magnitude of growth response to recombinant human GH (rhGH) therapy in short children with or without GH deficiency. We investigated this association in a large multinational cohort from the Network of European Studies of Genes in Growth (NESTEGG), comprising short children born small for gestational age (SGA). DESIGN: The study included short prepubertal SGA children treated with rhGH for 1 or 2 years. POPULATION: Two hundred and forty white Caucasian SGA children (138 male, 102 female) aged 6.6 +/- 2.3 years with a height at -3.0 +/- 0.7 SDS at start of rhGH treatment; 193 ethnically matched controls. METHODS: The GHR polymorphism (fl/fl, fl/d3 or d3/d3) was genotyped by polymerase chain reaction (PCR) multiplex assay. Growth velocity (G/V) in cm/year and changes in GV during the first and second year of rhGH treatment were evaluated. RESULTS: The change in GV was significantly greater in SGA children carrying one or two copies of the d3-GHR allele (P = 0.038 for the first year and P = 0.041 for the second year of GH treatment), but the change in height was not significantly different. Birthweight was significantly lower in SGA children with the d3/d3 genotype than in SGA children with the fl/fl genotype (P = 0.034) and in those with the fl/d3 genotype (P = 0.016). CONCLUSION: Our data, based on a large cohort, showed that the exon 3 GHR polymorphism is associated with responsiveness to rhGH treatment in SGA children with short stature.

[Percutaneous closure of three septal defects by two Amplatz occluders implanted during the same procedure]. / Fermeture percutanée de 3 communications interauriculaires par 2 dispositifs d'Amplatz implantés au cours d'un même cathétérisme.

Multiple atrial septal defects can be closed by interventional catheterisation. The procedure requires an accurate morphological evaluation: number of defects, distance from their edges to the main cardiac structures, resistance of the septum. The authors report the case of a 63 year old woman presenting with cardiac failure in whom 3 atrial septal defects were diagnosed. All 3 defects were successfully closed by the implantation of two Amplatz devices. Control echocardiography at 6 months showed the occluders in a normal position with no residual shunt and the patient was asymptomatic.

[Home blood pressure monitoring in addition to office blood pressure determination is useful in patients with systolic hypertension before their inclusion into a drug trial]. / L'automesure tensionnelle en complément de la mesure de consultation est utile pour l'inclusion dans un essai clinique de sujets avec une HTA systolique.

OBJECTIVE: In patients with uncontrolled systolic hypertension, to estimate the value of home blood pressure monitoring in addition to office blood pressure for inclusion in a trial. METHODS: 80 patients with systolic hypertension, defined as SBP > or =140 mmHg and pulse pressure > or =60 mmHg, were treated for 4 weeks with a thiazide diuretic at usual dose (25 mg HCTZ or 1.5 mg indapamide or methyclothiazide 5 mg). Blood pressure was measured using an automatic monitor (Omron M6) at office and at home in the 3 days prior the visit. Subjects with an uncontrolled hypertension were included in the second part of the trial only if there fulfilled inclusion criteria: office SBP > or =140 mmHg and home SBP > or =135 mmHg (mean of 18 measurements obtained on 3 consecutive days) and office pulse pressure > or =60 mmHg. RESULTS: After 4 weeks with diuretic treatment, 62% of patients fulfilled 3 criteria and were included in the second part of the trial. It was observed 76% of patients with office SBP > or =140 mmHg, 72% with office pulse pressure > or =60 mmHg and 70% with both office SBP and PP criteria. However, only 67% of patients had home SBP > or =135 mmHg. Discrepancy between office and home SBP was observed and subjects with a white coat hypertension was noticed in 14% and masked hypertension in 5%. CONCLUSION: If patients with systolic hypertension have to be included into a drug trial because there are uncontrolled, home blood pressure monitoring in addition to office blood pressure is a very useful criteria for inclusion because misclassifications due to white coat or masked hypertension is frequent in these patients.

[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.

Persistent and moderate hypercalcemia related to an ovarian clear cell adenocarcinoma: Pre- and postoperative parathyroid hormone related-peptide and 1,25-dihydroxyvitamin D3 levels.

OBJECTIVE: To evaluate the role of PTH-related peptide (PTH-rP) and 1,25-dihyhydroxyvitamin D3 in a case of hypercalcemia related to an ovarian adenocarcinoma. DESIGN: We report a case of humoral hypercalcemia in a patient aged 74 yr with a clear cell adenocarcinoma of the right ovary at an early stage of its development (stage T1aN0M0) revealed by moderate and persistent hypercalcemia (variable level between 2.7 and 3.2 mmol/l without any treatment) over six months. METHODS: PTH-rP and 1,25-dihydroxyvitamin D3 were measured in blood samples taken before and after hysterectomy and bilateral salpingooophorectomy and in blood samples taken intraoperatively from the right ovarian vein and a peripheral vein. RESULTS: High levels of plasma PTH-rP and 1,25-dihydroxyvitamin D3 concomitant with high serum calcium and low PTH levels were found before surgery, which was followed by normalisation of all parameters studied. A concentration gradient was found regarding plasma PTHrP (right ovarian vein 60.4 pmol/l, peripheral vein 4.5 pmol/l), not 1,25-dihydroxyvitamin D3. CONCLUSION: 1) moderate and persistent hypercalcemia can be observed at an early stage of an ovarian carcinoma; 2) the gradient of PTH-rP concentration between the samples taken from the right ovarian vein and a peripheral vein provides evidence for a direct secretion of PTH-rP by the ovarian tumor; 3) the increased 1,25-dihydroxyvitamin D3 level is not related to a direct ovarian production, but is a consequence of PTH-rP secretion.

[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.

[Management of hypertension and obesity: the observatory of management of uncontrolled hypertensives with respect to the presence or absence of overweight (PHYSIObs)]. / Prise en charge de l'hypertension artérielle et surcharge pondérale Observatoire de la prise en charge de patients hypertendus non contrôlés en fonction de la présence ou non d'un surpoids (PHYSIObs).

The object of this study was to compare the management of uncontrolled hypertensives (BP > 140/90 mmHg) by general practitioners with respect to the presence or absence of overweight (BMI > or =25 Kg/m2). A 2/1 stratification allowed comparison of 4080 patients who were overweight and 1951 patients with a normal body weight (normal BMI < 25 Kg/m2). The BP of patients who were overweight (> or =25 Kg/m2) was slightly higher than those with a normal BMI (161 +/- 12 mmHg vs. 159 +/- 12 mmHg, p < 0.001). The presence of a metabolic syndrome (43% vs. 7%, ATPIII criteria) was, logically, commoner in the patients overweight. However, the practitioners only recognised the presence of a metabolic syndrome in 65% of the overweight patients (28% true positives and 37% true negatives). The practitioners fixed their target value of systolic BP at 136.5 +/- 5.6 mmHg, in accordance with the recent recommendations of the Health Authorities. The targets were judged to be difficult to obtain in 18% of the overweight group and in 5% of patients with normal body weights. This optimism contrasted with the prescriptions, especially in the overweight patients, 46% of whom were treated by monotherapy and who remained for 44% on monotherapy at the end of the consultation. This descriptive study confirms the lack of awareness of the metabolic syndrome in overweight patients and identifies barriers to effective management of the hypertension of these high risk patients.

[Prescriptions following acute coronary syndrome]. / Ordonnance de sortie après syndrome coronaire aigu.

Each year in France, 150,000 to 180,000 new patients are the subject of prescriptions following acute coronary syndrome with or without ST segment elevation. There are two targets of the treatment, atherosclerosis, a diffuse, evolving trouble which, in this situation, is coming out of an unstable phase, and the myocardium, which has often been revascularised and has suffered deterioration of its contractile and electrophysiological characteristics to a greater or lesser extent. Prescriptions, based on proven factors and always centred on hygiene and dietary advice and the use of a combination of statins and aspirin, are adapted to suit the atherosclerotic and myocardial risk assessed for the individual patient. The prescription starts off the secondary preventive phase. It marks the first stage of the follow up, which is inevitable though of variable duration, for a disease which may evolve. It is the first step in the accompaniment of an attentive, informed patient whose confidence has been restored and who must now avoid falling into the double trap of not taking the treatment sufficiently seriously or of obsessively over-reacting.

[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.

[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.

[Association between blood pressure level and the follow up of the guidelines concerning the use of self blood pressure measurement]. / Association entre le niveau tensionnel en consultation et le suivi d'un protocole d'automesure.

OBJECTIVES: To evaluate the characteristics of hypertensive subjects who practise self measurement of blood pressure (SMBP) and their conditions of use, and to identify the properties of subjects using SMBP according the usual guidelines. METHODS: In 531 consecutive hypertensive subjects, referred to hypertension specialists, possessing a SMBP a questionnaire evaluating the condition of use of SMBP was given. Subjects following the guidelines about the use of SMBP have been compared to those using SMBP without specific design of supervision. RESULTS: In this population, aged 62 +/- 14 years, with 57% of men and a mean blood pressure of 147 +/- 23/82 +/- 12 mmHg, the SMBP devices have been bought without medical advice in 50% of cases (265/531). In 45% of cases (239/531), SMBP were made at the wrist. SMBP device was used every days in 26% of cases, every weeks in 27% of cases, every month or more in 22% of cases and only in case of uneasiness in 25% of cases. Blood pressure was measured only in the morning in 25% of cases, in the morning and evening in 31%, only the evening in 8% and at any time of the day in 36% of cases. More frequently 2 BP measurements were realized (47%) and in 19% of cases 3 measurements have been performed. In 15% of cases, the measurements were performed on 3 or 4 days consecutively, more frequently (85%) the measurements were realized without specific design ("once in awhile"). The data of SMBP were noted and showed to the doctor in 34% of cases. Only 12% (64/531) of subjects followed the usual guidelines concerning the use of SMBP (2 or 3 measurements, in the morning and the evening, during 3 or 4 consecutive days). Subjects following the guidelines for SMBP use have a higher SBP at the office than those using SMBP without specific design of supervision (155 +/- 25 mmHg vs 146 +/- 22 mmHg; p<0.01). CONCLUSION: Among hypertensives referred to hypertension specialists most of subjects use SMBP device without a specific design of supervision. Subjects with the most severe hypertension are those who have the best formation for SMBP.
