Abstract
Abstract
Background
Cardiovascular diseases are the leading cause of death in women, killing sevenfold more women than breast cancer. Rates of hospital death for myocardial infarction in women, although decreasing, remains significantly higher than in men (more than double), especially among women under the age of 50. The occurrence of myocardial infarction in non-menopausal women is not unusual, and the incidence continues to rise. While women under the age of 60 accounted for less than 12% of patients with myocardial infarction admitted in 1995, they accounted for more than 25% in 2015. In addition to the traditional cardiovascular risk factors, women present specific ones linked to hormonal modifications, inflammatory high-risk profiles, and thrombophilia.
Purpose
We comprehensively and systematically collected all clinical and biological data and the results of morphological explorations in all women admitted for myocardial infarction under the age of 50 in high-volume French centres. To date, no systematic descriptive analysis has been carried out incorporating not only clinical, morphological, and extraordinary characteristics, but biological characteristics, in particular hormonal and immunological parameters.
Methods
This prospective, observational study included all women admitted for myocardial infarction under the age of 50 years at 30 centres in France from May 2017 to June 2019.
Results
The population comprised 314 women (mean age 44.9 years): 192 presented with ST-segment elevation myocardial infarction and 122 with non-ST-segment elevation myocardial infarction, 75% were current smokers, 35 had a family history of cardiovascular disease, 33% had a complication of pregnancy, and 55% reported recent emotional stress. Ten had a normal coronary angiogram. Independent predictors of premature MI, <35 yo, were cannabis use and oral contraceptive therapy. No deaths, but 3 strokes, 3 recurrent myocardial infarctions, and 1 serious bleed occurred during hospitalization. At 12 months, 2 deaths occurred but linked to progressive cancer, 25 patients had recurrent PCI, 4 symptoms driven. Otherwise, 90.4% were event free and 72% completely symptoms free.
Conclusion
The WAMIF study showed that most young women with acute myocardial infarction reported typical symptoms of chest pain, and modifiable cardiovascular risk factors, most commonly tobacco use. Gynaecological status, history of pregnancy complications, and non-compliance with non-indication of combined contraception were overrepresented, emphasizing the urge for a better cardiological and gynaecological network. The overall prognosis for these women was better than previously reported despite the high rate of emergency consultations in the year following the index myocardial infarction, highlighting the need for more comprehensive follow-up following the myocardial infarction.

Abstract
Cardiovascular risk is one of the major challenges of menopausal hormone therapy (MHT). Thus, during a consultation of menopause, it is essential to considering the classic cardiovascular risk factors but also those more specific to women in order to evaluate the level of cardiovascular risk: high risk, intermediate risk or low risk. Cardiovascular disease (myocardial infarction or ischemic stroke) are rare disease in women compared to men. However, they represent the leading cause of death in women after menopause in France. Publications of randomized trials have widely questioned the expected benefit of MHT on arterial risk. It should be noted that almost all of these trials concerned the combination of orally conjugated equine estrogens (ECE) associated or not with medroxyprogesterone acetate. Meta-analyses of all randomized trials show an increased risk of ischemic stroke associated with the use of oral MHT while the use of transdermal estrogen therapy combined with progesterone will be safe. The risk of coronary heart disease is not increased and appears to be significantly reduced when the MHT is started less than 10 years after menopause or before the age of 60. These results suggest that the timing of initiation of the MHT, the type of MHT and all of the risk factors should be carefully considered before starting MHT.

Abstract
Can menopausal hormone therapy (HT) be used in hypertensive women? The group of experts of the French Society of Hypertension has carried out a review of the recent literature in order to answer this question, based on the most recent scientific publications. If use of oral HT is associated with a discreet increase in blood pressure, the transdermal route seems to be safer. The first results of major randomized trials of HT had alerted to an increase in cardiovascular events and breast cancer with the use of oral HT, generally, tipping the benefit-risk balance of the deleterious side. Complementary analyzes have shown the importance of the window of intervention (less than 10 years after the menopause) and the age of the woman to start the HT. On the contrary, they have shown a significant decrease of the coronary events. For woman suffering from hypertension and important climacteric symptoms, it is important to evaluate the whole cardiovascular risk in order to decide the possibility of prescribing a HT. Thus, the group of experts proposes a prescription assistance algorithm based on the stratification of cardiovascular risk, always favoring, when it is authorized, HT by transdermal route of administration.

Abstract
Clinic-ambulatory blood pressure (BP) difference is influenced by patients- and device-related factors and inadequate clinic-BP measurement. We investigated whether nonadherence to antihypertensive medications may also influence this difference in a post hoc analysis of the DENERHTN trial (Renal Denervation for Hypertension). We pooled the data of 77 out of 106 evaluable patients with apparent resistant hypertension who received a standardized antihypertensive treatment and had both ambulatory BP and drug-screening results available at baseline after 1 month of standardized triple therapy and at 6 months on a median of 5 antihypertensive drugs. After drug assay samplings on study visits, patients took their antihypertensive treatment under supervision immediately after the start of the ambulatory BP recording, and supine clinic BP was measured 24 hours post-dosing; both allowed to calculate the clinic minus daytime ambulatory systolic BP (SBP) difference (clinic-SBP–day-SBP). A total of 29 (37.7%) were found nonadherent to medications at baseline and 38 (49.4%) at 6 months. At baseline, the mean clinic-SBP–day-SBP difference in the nonadherent group was 12.7 mm Hg (95% CI, 7.8–17.7 mm Hg,
P
<0.001). In contrast, clinic SBP was almost identical to day-SBP in the adherent group (clinic-SBP–day-SBP difference, 0.1 mm Hg; 95% CI, −3.3 to 3.5 mm Hg;
P
=0.947). Similar observations were made at 6 months. Using receiver operating characteristics curves, we found that a 6 mm Hg cutoff of clinic-SBP–day-SBP difference had 67% sensitivity and 69% specificity to predict nonadherence to the triple therapy at baseline. In conclusion, a large clinic-SBP–day-SBP difference may help discriminating between adherence and nonadherence to treatment in patients with resistant hypertension.

Abstract
AIM Masked hypertension (MH) is defined by a normal office blood pressure (BP) and a high ambulatory BP. MH is characterized by high prevalence and poor cardiovascular prognosis. The aim of this study was to evaluate the usefulness of routine MH screening, using 24-h blood pressure monitoring (BPM), among patients with peripheral arterial disease (PAD). METHODS Between 2011 and 2013, 54 patients with PAD were included in the Hypertension and Vascular Medicine Unit of the Lille Hospital. They had normal office BP (< 140/90mmHg). A 24 h-BPM device was set on each patient. MH diagnosis was established if the BP average over 24 hours was ≥ 130/80 mmHg and/or the daytime average ≥ 135/85 mmHg and/or the nighttime average ≥ 120/70 mmHg. RESULTS MH prevalence was about 42.6% (23 patients). It was significantly more frequent in diabetic patients (odds ratio: 3.8 [1.1-12.8]), in patients with known hypertension (odds ratio: 5 [1.5-16.9]) or with high normal office BP (<140/90 mmHg but ≥ 130/85 mmHg) (odds ratio: 5.6 [1.7-18.2]). By multivariate analysis, only known hypertension and high normal office BP were associated with masked hypertension. CONCLUSION The high prevalence of MH in patients with PAD shows us the importance of a careful screening of MH in this population, especially in diabetic patients, in patients with known hypertension or with a high normal office BP.

Abstract
Cardiovascular (CV) diseases are the primary cause of death of women. Since they kill 10 times more than breast cancer, preventive measures should be implemented. According to U.S. recommendations, a woman is either at "CV risk" or at "optimal health status" if she has no risk factors and a perfectly healthy lifestyle. Some risk factors are more deleterious to women (smoking, diabetes, stress, depression, atrial fibrillation); or specific to women (preeclampsia, gestational diabetes, contraception, menopause, headaches). The lifestyle plays a key role for them. The blood pressure measurement is the most frequent opportunity to detect women at risk. CV tests should be performed to all symptomatic women and for those over the age of 45 who want to start practicing sport. The cardiologist can play a key role to improve women's CV health by integrating their hormonal risks. Women themselves can also make a powerful contribution to prevention by adopting a healthy lifestyle. From those recommendations concerning women's CV health, there is a great opportunity to initiate a health path for women at high cardiovascular risk. The objectives of the specific path "heart, arteries and women" of University hospital of Lille will be to improve professional practice, awareness of women, educate public authorities and within a few years reduce the epidemic of CVD of French women.

Abstract
BACKGROUND Therapeutic inertia (TI) is a recent concept still unknown by many physicians. In chronic diseases such as hypertension, it is defined as the tendency of physicians not to increase or change antihypertensive medications when the target blood pressure is not reached. Acting on TI could improve blood pressure control in France. METHOD This was a single-center prospective pilot study conducted by hypertension specialist physicians at the University Cardio-Vascular Center in Lille (France). It was conducted between March and June 2011. Data was collected from 161 hypertensive patients (mean age: 61.64±11.18 years; 98 (60.9%) male; 75 secondary prevention patients). Each physician completed a questionnaire on therapeutic inertia. TI was defined as a consultation in which treatment change was indicated (systolic blood pressure [BP]≥140 and/or diastolic BP≥90mmHg in all patients), but did not occur, with absence of an adapted justification of this choice. We considered as an adapted justification: a white coat effect demonstrated by ambulatory blood pressure monitoring (ABPM) or home blood pressure monitoring; scheduled reassessment of the BP by ABPM; recent change in antihypertensive treatment (less than 4 weeks); hospitalization needed for complete evaluation of secondary causes of hypertension and a more detailed assessment of potential target organ damage in patients with grade 1 or 2 hypertension. Our study aimed to evaluate rates of TI, to identify factors associated with TI, and to test the TI questionnaire. RESULTS Therapeutic inertia as defined in this study occurred in 11 consultations (8.3%) of the 133 hypertensive patients having uncontrolled BP above or equal to 140 and/or 90mmHg. Significant factors associated with TI were older age (Z=2.35, P<0.05) and sleep apnea syndrome (χ(2)=8.33, P<0.05). The absence of ambulatory blood pressure monitoring before the consultation (χ(2)=4.28, 0.1>P>0.05) and the number of consultations (Z=1.92, 0.1>P>0.05) exhibited a significant trend to be associated with TI. CONCLUSIONS Although the rate of TI was low in our study conducted in a specialized center, a well-accepted definition of therapeutic inertia would be useful for further study. The feasibility of using the questionnaire tested with this study shows that this measurement tool could help physicians become more aware of TI, both in the hospital and primary care setting. Further multicenter studies are needed for validation.

Abstract
This clinical case illustrates the management difficulties encountered during gestational hypertension and its impact on maternal and foetal outcome. Typically, preeclampsia occurs at the end of the second trimester. If blood pressure remains high early during pregnancy, a secondary cause of hypertension such as renal artery fibromuscular dysplasia should be explored. A renal vascular etiology can be safely ruled out with a duplex ultrasound. In this particular case of renal vascular hypertension in a patient with a single kidney, angioplasty appeared to be the sole solution and was efficient.

Abstract
A 24-year-old African who had been living in France for few years first consulted at our institution for severe systemic hypertension. He had no prior medical or surgical history. The patient was strictly asymptomatic. Except for systemic hypertension at both arms, the basic physical examination was normal with no cardiac murmur and no pulse deficit. A 24-hour ambulatory blood pressure monitoring performed before the consultation confirmed the presence of systemic hypertension with a mean blood pressure at 155/90mmHg during the day and also during the night under anti-hypertensive treatment. Ankle-brachial index measurement was low at 0.8 at both legs. Subsequently, a trans-thoracic echocardiography (TTE) and an aortic CT-scanner were performed. The TTE did not find any abnormalities including no aortic dilatation or no ventricular hypertrophy. The CT-scanner revealed a partial aortic coarctation. The patient underwent aortic surgery and recovered in few days with quite normal blood pressure under medical treatment. In conclusion, systematic ankle-brachial index is useful and recommended in every patient at first visit for systemic hypertension. Its safety and simplicity make it an essential tool in the management of systemic hypertension especially in populations with no systematic screening of aortic coarctation in childhood. It was in the present case very useful for the final diagnosis and treatment. In addition, it is an efficient tool to screen patients with asymptomatic peripheral artery disease and it can help for stratification of cardiovascular risk.

Abstract
Created in 2004, the HTA vasc healthcare network intensified detection, multi-disciplinary management and follow up of atheromatous cardiovascular disease and complicated hypertension in the Nord Pas de Calais region. The participating doctors gave their patients a Patient Dossier, as a function of predefined inclusion criteria (patients at elevated cardiovascular risk, as defined by the Haute Autorité de Santé (Higher Authority of Health) stratification. The dossier was presented in the form of a file containing all the information needed to optimise multi-disciplinary management, while at the same time reinforcing therapeutic compliance by patients. Therapeutic education workshops were organised, in order to complement the existing service. In parallel, HTA vasc set up a pilot medical education programme for vascular rehabilitation in six hospitals in the region. HTA vasc also established partnerships with other healthcare networks in the region. A patients' association 'Notre Coeur, Nos Artères', (Our Hearts, Our Arteries) was created in September 2006. About 250 healthcare professionals had joined the network by the end of January 2006, an increase of almost 40% over the year. More than two thirds were independent doctors, and they included cardiologists, neurologists, nephrologists, diabetologists, general practitioners, radiologists, cardiovascular surgeons, rehabilitation doctors, paramedics and pharmacists. More than 260 patients received a follow up dossier. The results of a survey carried out in May 2006 showed a high level of satisfaction: 82% of patients considered the Patient Dossier to be useful and appropriate; 78% of the healthcare professionals stated that the network was of help in the management of patients. HTA vasc received the scientific support of the Sociétés Françaises de Médecine Vasculaire, d' Hypertension Artérielle (French Societies of Vascular Medicine and Hypertension), and the Vascular Group of the Société Française de Cardiologie, with an external audit of the tools and activities undertaken in the region.

Abstract
Diagnosis of renal artery stenosis (RAS) should be discussed in numerous clinical situations including refractory high blood pressure (HBP), HBP in a polyvascular patient, degradation of renal function following renin angiotensin inhibitor or flash pulmonary edema. Ultrasound-doppler coupled with gadolinium-enhanced MR or CT angiography has proven adequate for most patients with RAS. Digital subtraction angiography should be limited to revascularisation procedures. Functional testing are not sensitive or specific enough because the degree of renin activation differs widely among patients with RAS. Renal percutaneous angioplasty induces a light to moderate decrease in blood pressure, has no effect on renal function but allows to reduce the number of anti-hypertensive drugs. Stenting completed angioplasty is worthwhile in most patients with atherosclerotic RAS. ACE inhibitors decrease mortality and increase renal function in patients with RAS.

Abstract
INTRODUCTION Metabolic syndrome (MetS) was defined by association of abdominal obesity, hypertension, glucose intolerance and/or dyslipidemia. The objective of this study was to compare the new International Diabetes Federation (IDF) definition and the National Cholesterol Education Program Adult Treatment Panel III (NCEP) definition and their association with cardio-vascular disease in hypertensive patients. POPULATION AND METHOD Two hundred and thirty hypertensive patients were hospitalized successively for cardio-vascular disease exploration and hs-CRP measurement. The stratification of cardio-vascular risk was made according to the French recommendations. The IDF definition and the NCEP definition were compared according frequency of resistant hypertension and cardio-vascular disease extension. RESULTS In our study, high cardio-vascular risk hypertension represented 68.5% of patients. Diabetes was present in 23.5% of them and obesity in 45.5%. Patients with cardio-vascular disease represented 60% of our study population. Prevalence of MetS was 38.5% according to the NCEP definition and 59% according to the IDF definition. The NCEP definition was allowed to select subjects with widespread vascular disease and resistant hypertension whereas the IDF definition did not. These results could be explained by lower waist circumference and glycaemia cuts offs according to the IDF criteria. When diabetic's patients were excluded, MetS was not associated with increase of resistant hypertension frequency. Moreover, hs-CRP was independently associated to the extension of the cardiovascular disease and smoking remained the most powerfully factor associated to the cardio-vascular disease extension. CONCLUSION In hypertensive patients, the NCEP definition seems more adapted to the diagnosis of MetS than the IDF one. Abdominal obesity could be the indispensable element to the MetS diagnosis but according to the NCEP waist circumference cut off. The use of this syndrome seems to be relevant to select the patients presenting an intermediate cardio-vascular risk in order to adapt treatment.

Abstract
The aim of this observational study was to assess whether there were differences in perception of overall cardiovascular risk (OCVR) in hypertensive patients depending on the gender of the primary care provider (PCP). We performed this study in 2003: 2979 male PCPs (MPCPs) and 562 female PCPs (FPCPs) participated throughout France. The patients included were hypertensive either treated or untreated, uncontrolled (blood pressure (BP) >or=140/90 mm Hg) with at least one other cardiovascular risk factor (CVRF) associated. OCVR of patients was both calculated according to French Agence Nationale d'Accréditation et d'Evaluation en Santé guidelines for uncontrolled hypertensive patients and subjectively estimated by the PCP as 'low', 'moderate', 'high' or 'very high'. About 11 770 patients were included, mean age was 63.7+/-11.2 years and 54.1% were men. Mean BP was 157+/-13/90+/-9 mm Hg. According to French guidelines, the calculated OCVR was 'moderate' in 23.7% of patients, 'high' in 47.5% and 'very high' in 28.8%. The PCP perceived OCVR was that 9.1% of patients were considered to be at 'low risk', 40.7% at 'moderate risk', 38.1% at 'high risk', and only 11.2% at 'very high risk' (OCVR was not estimated for 0.9% of patients). The overall agreement rate between the PCPs' estimation of OCVR and its calculation was 43.5%. Thus, in spite of extensive diffusion of ANAES guidelines, we found that PCPs in France generally underestimated OCVR though there were no significant differences between male and female physicians (45% for FPCPs and 43.2% for MPCPs).

Abstract
Peripheral arterial disease (PAD) remains an under-diagnosed affection, and the ankle-brachial index (ABI), a simple diagnostic method, is poorly known and seldom used, and the vascular patient's prescription list is frequently insufficient regarding results obtained in large trials with good methodology. The French ATTEST study underlines the fact that ABI is measured in less than 1 out of 3 patients with PAD. In ATTEST study, less than 10% have the triple therapy validated in PAD : antiplatelet drugs, statins and ACE-inhibitors. The international REACH registry included more than 60 000 patients suffering from atherosclerosis, including 8 000 cases with PAD. This survey evidences that in PAD patients, the annual cardiovascular complication rate is significantly higher than in patients with coronary artery disease (18 vs 13%); again PAD appears systematically under-treated when compared to CAD. These epidemiological surveys highlight the importance of screening of atherosclerotic lesions with the aim of setting an active prevention of CV complications. The new guidelines insist on the screening of PAD in patients at risk, as well as on the importance of the global management after initiating the triple therapy, independent of the CV risk factors. In a 5-year longitudinal study from an initial cohort of 2265 subjects, Aboyans et al. studied the progression of PAD by repeated measurements of ABI at the level of ankles and toes. Factors of progression for large-vessels PAD were active smoking, the total/HDL-cholesterol ratio, Lp(a) and CRP. Importantly, diabetes was not associated to the PAD progression in large vessels, but in contrast, it was the sole factor associated to the progression of PAD in small vessels. In an Austrian study published this year in the NEJM, Schillinger et al. compared balloon angioplasty versus the use of Nitinol stent for the treatment of long stenoses of the superficial femoral artery. In case of claudication, these lesions are usually treated medically, whereas surgery is required for more severe cases. The fact that stenting these long lesions of the superficial femoral artery provides benefits in terms of restenosis opens a approach for the endovascular therapy, to be confirmed by larger trials.

Abstract
Usefulness of magnetic resonance angiography in the screening of renal artery stenosis in hypertensive patients: proposition of a diagnostic algorithm: a study on 245 patients. Different non-invasive techniques, including Duplex, spiral angioscan, and magnetic resonance angiography (MRA) are available for the diagnosis of renal artery stenosis (RAS). The aim of this study was to assess the diagnostic performances of MRA and the MRA-Duplex couple in the diagnosis of RAS. Between September 2003 and January 2005, 245 patients benefited from a renal MRA for the assessment of hypertension etiology. The MRA-Duplex couple was performed in 228 patients. Renal arteriography was performed in case of abnormalities observed with MRA and/or Duplex (n=41). The sensitivity and specificity of MRA were respectively at 100% and 23%. The sensitivity was notably higher in the right renal artery (100 vs. 73%). The sensitivity and specificity of Duplex were respectively at 71 and 85%. The concordance between the two exams was disappointing (kappa at 0.39 for the right side and 0.62 for the left side), leading to the interest of the MRA-Duplex association for excluding the presence of RAS (sensitivity and negative predictive value=100%). However, using the MRA-Duplex couple led to a high number of false positive cases, due to MRA, leading to 11 angiograms out of 41 exams, without any significant RAS. In case of suspicion of RAS, the MRA-Duplex couple permits to exclude definitely the diagnosis of RAS. In case of discordance between the 2 exams, it would be useful to require a spiral angioscan and/or redo a Duplex exam using contrast agents, prior to angiography with a therapeutic goal. These management modalities might be useful to avoid the number of normal angiograms, with an inherent risk of complications and cost excess.

Abstract
A 20-year-old woman consulted for severe hypertension which revealed aneurismal stenosing fibrodysplasia of the renal arteries. The diagnosis was established by duplex Doppler which visualized tight stenosis of the distal portion of the right renal artery and the proximal portion of the left, associated with aneurismal lesions downstream from the strictures (1.8 cm on the right and 1.3 cm on the left). The lesions were highly suggestive of fibrodysplasia and were confirmed by magnetic resonance angiography. Endoluminal revascularization was undertaken because of the severe hypertension and the presence of arterial lesions. Revascularization was unsuccessful and severe hypertension persisted. Surgery was performed in two stages. The first procedure consisted in resection of the left aneurismal lesion with aortorenal internal saphene bypass. Secondarily, exclusion of the right aneurysm was performed with cure of the stricture by extracorporal renal surgery with anastomosis of the renal artery to the aorta and the renal vein to the vena cava. Clinical outcome was favorable. Angioscan and duplex Doppler controls at three and six months confirmed the anatomic success of the revascularization. Aneurysm of the renal artery, like renal artery stenotic dysplasia, is a rare but probably underestimated condition due to insufficient screening. This diagnosis should be entertained in hypertensive young women. There is risk of rupture of the aneurysm. Aneurysmal lesions can be associated with renal artery stenosis which usually involves a short segment of the artery, as in our case. Renal aneurysms should be treated when one of the following elements is present: aneurysm measuring more than 20 mm, progressing aneurysm, dissection, discovery in a patient with a renal risk (single kidney, renal insufficiency), desire for pregnancy, severe hypertension recently discovered in a young subject associated with dysplastic stenosis, isolated aneurysm associated with recent severe hypertension, as reported here.

Abstract
It is illusory to think that one year is long enough to establish all the truths that will guide our clinical practice in vascular medicine. On the contrary, one year was long enough to contradict what the preceding twelve months had set out to demonstrate. Consequently, promising trials in the treatment of abdominal aortic aneurysms by endoprostheses have been the object of contradictory debate with regards to the long-term benefits. In fundamental research, circulating progenitors of endothelial cells have been shown to be a marker of atherosclerosis, but is it a better marker than LDL-cholesterol values? The demonstration that these progenitors are of value in the treatment of essential ischaemia of the lower limbs is awaited. Finally, ximelagatran, a direct thrombin antagonist, seemed to have all the qualities of an ideal anticoagulant: easy to use, safe... until the report of raised hepatic enzymes, the clinical relevance of which remains to be determined. In the good news section: the Systolic Pressure Index, an unquestioned marker of arterial disease. Its reduction was known to be correlated with the prevalence of cardiovascular complications. However, it has now been shown that an increase in the index is also associated with cardiovascular complications, a real U-shaped curve. Renal arterial stenosis should be considered in patients with left ventricular failure presenting with flash pulmonary oedema. In the absence of cardiac pathology, BNP would seem to be a good biological marker of haemodynamically significant renal arterial stenosis. Finally, should superficial femoral artery stenosis be treated by an active stent. To date, there is no formal proof.

Abstract
UNLABELLED For some years now, the recommendations of scientific societies have significantly reduced the therapeutic targets for blood pressure, glycaemia and lipid levels in diabetic patients. However, little is known regarding the synchronization between effective risk factor management and the guidelines. To examine this issue, the Phenomen survey was conducted between January and July 2001 on 16358 patients suffering from hypertension followed by a general practitioner in France. AIM To evaluate the control of cardiovascular risk factors in patients with diabetes and hypertension according to the French guidelines. METHODS AND PATIENTS 8177 general practitioners, selected from a national database according to quotas, taking into account age, practice and area, had to include the first two hypertensive patients they came across in their practice and to collect their demographic data, cardiovascular risk factors and medications. RESULTS 2346 out of 16358 hypertensive patients presented with type 2 diabetes (14.3% of the cohort). The number of GP consultations in the last 12 months averaged 8.31. According to the French guidelines, 6.5% had a blood pressure<140/80 mmHg, a total of 38.7% patients met the goal of LDL cholesterol level and 26.6% of patients had an HbA1c<6.5%, 53.4% of patients had an HbA1c between 6.6 and 8%. 37.1% of patients continued to receive antihypertensive monotherapy but only 3% in this monotherapy group reached the target of 130/85 mmHg. 29% of the patients were on antiplatelet therapy. 64.6% of these hypertensive diabetic patients presented with more than three other cardiovascular risk factors. Based on WHO recommendations, 0.3% of the patients met all of the blood pressure, lipid and glycaemic treatment objectives. CONCLUSION Despite frequent monitoring by a general practitioner, the overall management of modifiable risk factors in this diabetic hypertensive population is clearly inadequate. The impact of the guidelines on effective management remains limited and additional information is required to understand why physicians are not more aggressive in managing modifiable risk factors in diabetic patients.

Abstract
The wealth of information in vascular pathology merits close examination. The French Cardiology Society vascular group turned its attention to arteries, veins, hypertension and a more fundamental investigation to analyse the results from some illuminating studies which appeared in 2004, despite some pertinent therapeutic doubts. Examination of the trials discussed here shows the importance, as much in vascular pathology as elsewhere, of founding our practice on evidence based medicine.

Abstract
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.

Abstract
The indication of renal atherosclerotic artery stenosis revascularisation is always debated in clinical practices when arterial hypertension is stabilized by the treatment, especially if the stenosis is discovered fortuitously. The clinician needs clinical and morphological markers which will indicate or not the revascularisation in the situation of "nephronic protection". The benefits of angioplasty have been studied on the blood pressure, the creatinine clearance, the glomerular function analyzed by scintigraphy, the renal length and more recently on the mean cortical thickness (MCT). The follow-up of these studies is generally inferior to 2 years. In this work, we tried to estimate the clinic and morphologic evolution 5 years after a unilateral artery stenosis angioplasty. From a group of 249 patients who had a renal angioplasty between January 1995 and January 2000 (T0), 29 patients with refractory hypertension and with a unilateral atherosclerotic renal artery stenosis on spiral computed tomographic angiography (TCA) performed at T0 [17 M; 12 W; medium age 68.6 +/- 10 years] were included. The TCA performed at 5 years (T5) eliminated a new renal arterial stenosis or restenosis. We have analyzed 29 revascularized kidneys (kidney S) and 29 controlateral kidneys (kidney C), the blood pressure and renal function. The renal length (mm) was at T0: kidney C=99.4 +/- 13.5; kidney S=93.5 +/- 10.8 and at T5: kidney C=99.4 +/- 12.6; kidney S=94.2 +/- 10.7. MCT (mm) was at T0: kidney C=7 +/- 1.2; kidney S=6.6 +/- 1.1 and at T5: kidney C=6.2 +/- 1.2; kidney S5=6 +/- 1. The cortical atrophy got worse while the renal length and creatinine clearance were stable: only diastolic blood pressure was controlled (78.8 mmHg +/- 11.9). In spite of small strength, this study arguments the fact that the angioplasty isn't sufficient to control the arterial hypertension in an atheromatous context, not allowing to slow the evolution of distal cortical lesions with however a stability of creatinine clearance.

Abstract
UNLABELLED Decrease in sexual desire is a disturbance affecting treated hypertensive subjects of both sexes. In contrast with erection problems, this abnormality has rarely been studied in hypertensives treated with antihypertensive drugs. OBJECTIVES To evaluate, using a self-administered questionnaire, the prevalence of sexual disturbance (decrease in sexual desire) in treated hypertensive subjects and to determine the management of these troubles. METHODS In 428 hypertensive subjects, living in France and referred to hypertension specialists, a self-administered questionnaire evaluating the quality of sexual activity was given before the consultation. Nine specific questions focused on the quality of sexual function for the last 6 months in men or women (interest for sexuality, sexual desire, sexual pleasure). Secondly, the doctors were questioned about their management of these sexual disturbances. RESULTS In this population of treated hypertensives, including 270 men and 158 women, with a blood pressure level of 139 +/- 20/84 +/- 13 mmHg, a decrease in sexual desire was reported by 47% of men (127/270) and 48% of women (76/158). Sexual disturbance was related to antihypertensive drugs in 46% of cases (93/203), more often in men (59% [75/127]) than in women (24%, [18/76]), p < 0.001). In subjects with sexual disturbance, a specific medical management has been proposed in 35% of cases (71/203), especially in men (in 46% of cases [58/127], and consisted in a specialized consultation for 34% (43/127) and/or the prescription of Sildenafil for 20% (26/127). In women, the lack of management of these troubles was more often observed than in men (82% vs 54%; p < 0.01). Modifications of antihypertensive treatments were rarely observed in 15% of cases (30/203) comparatively in men and women. CONCLUSIONS Men and women with treated hypertension are at "high risk" of sexual disturbance. Management of sexual dysfunction in these subjects concerns only 35% of cases, especially men, including specific treatments and/or consultations, but changing in antihypertensive drugs still remains rare.

Abstract
UNLABELLED According to ANAES guidelines (2000) adapted from the international guidelines, kidney function should be regularly monitored in hypertensive patients in order to detect vascular nephropathy at an early stage and prevent kidney failure which is a major cardiovascular factor. The PHENOMEN survey was conducted between January and July 2001 on a representative sample of 16,358 patients suffering from hypertension being followed by a General Practitioner (GP). The population included patients from all 22 administrative regions in France. AIMS To determine the prevalence of renal involvement in patients with hypertension (both treated and untreated); to compare the GP's subjective evaluation of the extent of renal involvement with a more objective assessment made according to ANAES guidelines. METHODS Kidney function was evaluated by measuring plasma creatinine levels to derive a value for the creatinine clearance rate (CCR) using the Cockeroft-Gault formula. RESULTS Out of the 16,358 patients included, plasma creatinine levels could be measured in 11,586 (76%) [53% men; 47% women, mean age = 63 +/- 12 years]: mean plasma creatinine = 90 +/- 49 mumol/l, i.e. a mean CCR of 83 +/- 32 ml/min. For 8,650 of the patients (75%), kidney function had been monitored in the preceding twelve months. The physicians defined their patient's kidney function as normal in 10,080 (87%) of cases whereas in reality, 4,411 of 8,650 (51%) were suffering from some degree of renal insufficiency (RI): in 2,422 (28%), RI was mild (> or = 60 CCR < 80 ml/min): in 1,903 (22%) RI was moderate (> or = 30 CCR < 60 ml/min). A minority of patients (44 i.e. 1%) showed severe RI (CCR < 30 ml/min). CONCLUSION Most GPs apply ANAES guidelines and order plasma creatinine assays. However, there is a discrepancy between how the physician "perceives" the seriousness of the renal insufficiency and a more objective measure based on the CCR figure. It would seem that the CCR derivative is insufficiently exploited despite the widespread availability of converters. Thus, the PHENOMEN survey has revealed that the extent of renal involvement in patients with hypertension still tends to be underestimated by GPs despite the major implications of this complication in terms of therapeutic strategy and global cardiovascular risk.

Abstract
OBJECTIVES to identify pre-operative factors that could predict complications following from transluminal repair of abdominal aortic aneurysms (AAA). METHODS during a 5-year period, 96 consecutive patients underwent elective endovascular treatment of a AAA. In all patients, helical CT and/or Magnetic Resonance Imaging (MRI), and plain abdominal roentgenogram were performed at 1, 3, 6, 12, 18, and 24 months and yearly thereafter. Angiography was performed systematically 1 year after the stent-graft implantation, or earlier if helical CT or MRI diagnosed an increase in the maximal transverse diameter or a high flow endoleak. RESULTS early (<30 days) morbidity (12%) was significantly increased by pre-operative renal insufficiency (p < 0.01). Early mortality (2%) correlated with ASA score (p = 0.01). Median follow-up was 27 months (range 3-66). Mortality (12%) during follow-up was correlated to the pre-operative coronary status (p = 0.01). A type I endoleak was diagnosed in 18 patients (19%). Common iliac artery diameter was correlated with the presence of type I endoleak (p < 0.001). A type II endoleak was diagnosed in 47 (49%) patients. The diagnostic of type II endoleak was significantly increased (p = 0.001) in patients with pre-operative patent IMA associated with more than four patent lumbar arteries. The anatomic characteristics of the aneurysm were correlated to the additional endovascular procedures during stentgraft implantation (p = 0.01), and to the implantation of a complementary iliac limb extension during follow-up (p = 0.01). CONCLUSIONS the risk factors determined by this statistical analysis could help surgeons to select more accurately patients suitable for endovascular treatment.

Abstract
OBJECTIVE evaluation and comparison of the endovascular treatment of isolated aortic and aortoiliac atherosclerotic lesions (stenoses and occlusions). METHODS a percutaneous endovascular procedure was performed in 52 patients (38 men and 14 women) with a mean age of 52 years (range, 25-85 years). The baseline angiogram showed 35 aortic lesions (31 stenoses, 4 occlusions) and 17 aortoiliac lesions (14 stenoses, 3 occlusions). Percutaneous techniques used in this series included variable combinations of transluminal angioplasty and stenting. All stents placements were performed over-the-wire using the transfemoral route (most often bilateral approach). Clinical examination and Duplex-scan were performed at discharge, 1 month, 6 months, 12 months, and then yearly. RESULTS technical success was 100% for aortic and aortoiliac lesions. Angiographic success rates were comparable for aortic (91%) and aortoiliac (94%) lesions. No death occurred during or early after the endovascular intervention. Duplex-scan confirmed 100% patency rate at discharge. There was no significant difference between the aortic (94%) and aortoiliac (96%) groups regarding immediate clinical improvement. Mean follow-up was 34+/-31 months (range, 0-130 months). The cumulative primary patency rate at 36 months was 85% in the aortic group and 86% in the aortoiliac group. Clinical success, defined as a symptom-free status at the end of follow-up, was also similar in both groups. CONCLUSION endovascular treatment of isolated aortic lesions of the infra-renal aorta has favorable outcomes comparable to those of aortoiliac lesions.

Abstract
OBJECTIVE To define the prevalence of cardiovascular risk (CVR) levels in a population of hypertensive patients (whether treated or not) monitored by General Practitioners, using the stratification system proposed by the ANAES in 2000. METHODS Between January and July 2001, a nation-wide survey was carried out based on a representative sample of 8,177 General Practitioners spread evenly throughout all of the 22 administrative regions in France. The evaluation of CVR levels took into account blood pressure readings as well as CVR factors and indicators. RESULTS This survey covered 16,358 patients (53.2% men, 46% women; mean age = 62.5 +/- 11.9 years; BMI = 27.3 +/- 4.5 kg/m2) with a mean history of hypertension of 7 +/- 7 years. The most common CVR factors were dyslipidemia (59.5%), smoking (19%) and diabetes (16%). Concomitant target organ damage was recorded in 17% and heart disease in 21.8%. One patient in four had more than three CVR factors; respectively 56.5%, 30.9% and 12.5% of the patients had mild, moderate or severe hypertension. More than 50% of the patients were classified as being at "high" or "very high" CV risk. The distribution of risk levels was similar throughout the country with a North-South gradient of the high/very high levels. Only 17% of the patients being treated had completely normal blood pressure (< 140/190 mmHg), although 19% more count as normal if the limit values are included. CONCLUSION The main objective of this large-scale, nation-wide epidemiological survey was to evaluate how well CVR is being managed in a representative sample of patients with high blood pressure. In general, none of the risk factors is adequately controlled, especially in populations considered as being at high CVR. Moreover, the notion of CVR has only been partially assimilated by General Practitioners.

Abstract
This clinical case illustrates the diagnosis of a secondary cause of hypertension in a patient with Von Recklinghausen's disease. The hypertension resulted from a complex malformation of the right renal artery and dysplasic stenosis of the left inferior polar artery treated successfully by simple angioplasty. This case illustrates the high proportion of vascular (renal artery dysplasia, coarctation of the aorta) and endocrine (pheochromocytoma) causes of hypertension in patients with neurofibromatosis.

Abstract
UNLABELLED Education of hypertensive subject must sensitize the patient to its pathway and to the prescribed treatment. Self-measurement of blood pressure, which directly implicates the patient, should ameliorate the education of hypertensive subject. OBJECTIVES To evaluate if the possession of a self-measurement blood pressure device improves patients' knowledge of hypertension. METHODS In 484 treated hypertensive subjects referred to hypertension specialists, a questionnaire evaluating patients knowledge of hypertension and its treatment was given before the consultation. During this consultation, the practitioner evaluated the concordance between antihypertensive treatments declared by the patient and those effectively prescribed. RESULTS In this population, aged 61 +/- 12 years, with 55% of men, a self-measurement blood pressure device was possessed by 165 subjects (34%). These devices have been bought without medical advice by 83 patients. For a minority of subjects (n = 41), self-measurements of blood pressure were made at the wrist. Blood pressure level was similar in subjects with (141 +/- 19/80 +/- 10 mmHg) or without (140 +/- 19/80 +/- 10 mmHg) self-measurement devices. Subjects possessing a self measurement device had a better knowledge of their usual blood pressure level and of the normal blood pressure values (< 140/90 mmHg), than subjects without self measurement device (93% vs 77%, p < 0.01, and 56% vs 33%, p < 0.01, respectively). Moreover, subjects in possession of self-measurement devices had a better knowledge of their antihypertensive treatment than those without device (83% vs 70%, p < 0.05). Logistic regression analysis including age, sex, smoking, education level, blood pressure level and the number of antihypertensive tablets confirm the statistical differences observed. CONCLUSION Hypertensive subjects who possess a self-measurement blood pressure device have a better knowledge of their hypertension. These results indicate that the possession of a self-measurement device contributes to the education of hypertensive patients.

Abstract
UNLABELLED Atheromatous renal disease is more and more involved in end stage renal failure in polyatheromatous patients. The goal of this work was to study the demographic differences between hypertensive patients with renal artery stenosis (RAS) or without RAS. METHOD Between November 1995 and July 1997, 49 hypertensive patients were included consecutively for a suspicion of RAS. Age, sex, hypertension history, tabagism, cardiovascular heredity, body mass index, diabetes history, hypercholesterolemia, kalmia, serum creatinine, creatinine clearance, systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure (PP) were studied. A renal echo-doppler and a renal TDM were performed in all patients. A renal arteriography was performed in 23 patients with a RAS suspicion after the two morphologic exams. The demographic characteristics of both clinical groups control (group 1) and patients with unilateral RAS (group 2), were compared. STATISTICS Descriptive analysis, Wilcoxon test, Khi 2 test, spearman correlation (p < 0.05). RESULTS Group 2 patients were significantly older than group 1 patients (p = 0.008) with a mean age difference of 8 years. Creatinine clearance was lower in patients suffering from RAS with a mean difference of 23 mL/min between groups 1 and 2 (p = 0.0007) but we also had to take into account the negative correlation existing between creatinine clearance and age (r = 0.63; p = 0.0001) when interpreting these results. The DBP was lower (p = 0.03) and the PP higher (p = 0.01) in group 2. The SBP was higher in group 2 but this result was not significant. Mean differences in SBP and PP between group 1 and group 2 were 6 mmHg and 15 mm Hg respectively. Smoking was more common in group 2 (p = 0.04). The history of hypertension, cardiovascular heredity, sex ratio (M/F), body mass index and prevalence of diabetic were comparable between the two clinical groups. CONCLUSION Although there were demographic differences between the two clinical groups, no clinical or biological variable could be used alone to identify which patients suffered from renal stenosis, because the distribution of these variables did not differ significantly between the two groups and the effective was small. Then, we thought that Krijnen's predictive rule is interesting in the screening of hypertensive patients with RAS suspicion.

Abstract
UNLABELLED Although the size of the kidney is still the most commonly used as morphological parameter, it is not enough sensitive for early detection of ischemic nephropathy. PURPOSE To study a novel method of renal morphology analysis using spiral computed tomography angiography (CTA) in hypertensive patients with or without unilateral atheromatous renal artery stenosis (RAS). METHODS Forty-nine hypertensive patients suspected RAS underwent spiral CTA. Arteriography showed significant RAS in 26 patients. Renal length, 3 upper and 3 lower cortical thicknesses were measured in 46 control kidneys (C) i.e. 23 patients without RAS (group 1), in 26 stenosed (S) and in 26 opposite kidneys (OPP) i.e. 26 patients with unilateral RAS (group 2). Mean cortical thickness (MCT), cortical area (CA), medullary length (ML) were calculated in the same groups. The reproducibility and agreement of measurements were investigated in two groups. The demographic parameters (age, sex, bodymass index, and history of hypertension) were correlated with morphological parameters in group 1. RESULTS The reproducibility and agreement of measurements were confirmed (R2 = 0.53 to 0.93) except for anterosuperior thickness. The C kidneys were of comparable morphology: MCT (mm) = 9.1 +/- 0.6; 9.2 +/- 1.0, CA (mm2) = 950 +/- 119; 934 +/- 157, ML (mm) = 85 +/- 11. In group of Opp kidneys, MCT = 7.9 +/- 1.4 mm, CA = 806 +/- 210 mm2, ML = 84 +/- 13 mm. In group of S kidneys, MCT = 6.6 +/- 1.6 mm, CA = 612 +/- 193 mm2, ML = 77 +/- 14 mm. Demographic parameters were not correlated to renal morphology. CONCLUSION Spiral CTA is a suitable method to study renal morphology. Cortical thickness and medullary length could be used to obtain a reliable diagnosis of early ischemic nephropathy.

Abstract
ARA-II: Angiotensin II receptor antagonists (ARA-II) belong to a recent class of antihypertensive drugs whose mechanism of action is similar to converting enzyme inhibitors (CEI). ARA-II are particularly interesting due to the excellent clinical and biological tolerance, similar to placebo, and their antihypertensive efficacy, comparable with classical drug classes. PUBLISHED TRIALS: A meta-analysis, published by Conlin in the American Journal of Hypertension, suggests that ARA-II, specifically losartan, valsartan, irbesartan and candesartan, have an equipotent blood pressure lowering effect. The careful lecture of this meta-analysis however discloses a faulty methodology from which no valid conclusion can be drawn. Since this early publication, several other comparative studies have been published. These multicentric, randomized double-blind studies enrolled a sufficient number of patients and demonstrated a clinical difference between certain ARA-II at usual dosages. CLINICAL PRACTICE: These studies do have an impact on everyday practice. For the practitioner, the goal is to obtain and then maintain a long-term and optimal reduction in the blood pressure level (reduction or prevention of target-organ disorders and cardiovascular complications of high blood pressure). This reduction in the cardiovascular risk will also depend directly on tolerance and compliance to the antihypertensive treatment. This element must also be considered in assessing treatment efficacy, independent of the blood pressure lowering effect. The results of several other studies will be published in 2001-2003. These large-scale studies on ARA-II related morbidity and mortality will be most useful in determining the role of these drugs in different therapeutic strategies compared with other drug classes.

Abstract
Helical CT angiography is increasingly used for the evaluation of the kidneys and the renal vessels. Knowledge of the potential variants in renal and renal vascular anatomy and of their appearances on helical CT are thus indispensable for radiologists who perform and interpret such examinations. We report six cases of anatomic variants that we encountered in our tertiary referral centre over the past 5 years, during which time we have performed 4850 helical CT angiograms, including 1432 renal artery examinations. These represent rarer anomalies in renal vascularization, most of which were associated with renal malformations (horseshoe kidney with or without cortical torsion, renal malrotation, single kidney, and thoracic origin of a renal artery). We present the helical CT findings and discuss the possible embryological mechanisms and the practical implications of these abnormalities for the radiologist.

Abstract
AIM To assess the feasibility and to demonstrate the potential clinical application of intravascular doppler in the evaluation of renal blood flow in patients with hypertension and normal renal arteries. MATERIALS AND METHODS Intravascular doppler was used to measure renal blood flow in 19 patients (34 kidneys) during arteriography to rule out renovascular hypertension. Arteriography showed no evidence of renal artery stenosis in any patient. Hemodynamic parameters, renal artery diameter, and doppler measurements were undertaken at baseline, after injection of a bolus (10 ml) of normal (0.9%) saline, and after injection of isosorbide dinitrate (1 mg diluted in 10 ml normal saline). RESULTS Repeated measurements of renal blood flow confirmed the reproducibility of the technique. Basal blood flow was similar in both right and left kidneys; injection of vehicle solution (10 ml normal saline) had no effect on doppler parameters. Injection of isosorbide dinitrate resulted in a significant increase in renal blood flow velocity reflecting an increase in renal blood flow; this demonstrates the existence of a renal flow reserve. The degree of increase in renal blood flow varied significantly between kidneys. CONCLUSIONS Intravascular doppler is a safe, effective, and reproducible technique for measurement of renal blood flow. It allows evaluation of variations in renal blood flow in response to diverse vasoactive drugs or other vasomotor stimuli. The present study demonstrated the heterogenous response of renal blood flow in response to vasodilator stimuli.

Abstract
Atheromatous ischaemic renal vascular disease (AIRVD) comprises ischaemic renal disease, atheromatous disease of the large arteries and intra-renal atheromatosis. Cholesterol emboli and lesions of nephroangiosclerosis are often associated, affecting the two kidneys. It is an increasingly common cause of chronic renal failure in an aging population, affecting 12 to 14% of new patients requiring dialysis in the United States. Atheromatous stenoses are very progressive with a risk of renal atrophy; they are a marker of polyvascular disease, often detected during other angiographic investigation. Hypertension secondary to the stenosis, still incorrectly called renovascular hypertension, is, however rare, affecting less than 0.5% of hypertensives. For economic reasons, it is important to select patients who need complementary investigation. In view of the absence of specific signs of the pathology, the "presumptive" diagnosis is based on a range of clinical and biological results, especially in a high risk context. The method of investigation varies from team to team, depending on the availability of equipment, the experience of the operators and the patient himself. Duplex Doppler, spiral angioscan and magnetic resonance angiography are the most pertinent investigations for the management of AIRVD. When the diagnosis of renal artery stenosis has been made, the problem of revascularisation, the objective of which is to preserve or restore the functional nephronic mass, has to be treated to prevent progression to end stage renal failure. Although epidemiological and physiopathological evidence is in favour of revascularisation, only renal salvage procedures are imperative. Apart from these indications, the clinical benefits of revascularisation have not yet been demonstrated. In all cases, the control of associated risk factors is essential to maintain the success of revascularisation and slow down the progression of atheromatous disease.

Abstract
PURPOSE To study the vasomotor responses of the renal microcirculation in patients with essential hypertension. METHODS We studied the reactivity of the renal microcirculation to papaverine, with intraarterial Doppler and quantitative arteriography, in 34 renal arteries of 19 hypertensive patients without significant renal artery stenosis. Isosorbide dinitrate was given to maximally dilate proximal renal arteries. APV (average peak blood flow velocity) was used as an index of renal blood flow. RESULTS Kidneys could be divided into two distinct subgroups based on their response to papaverine. An increase in APV of up to 55% occurred in 21 kidneys, an increase > 55% in 13 kidneys. Within each group the values were normally distributed. Both baseline APV and the effect of papaverine on mean velocity differed significantly between groups. CONCLUSION There seems to be a subgroup of patients with essential hypertension that has an impaired reactivity to papaverine, consistent with a functional impairment of the renal microcirculation. Further studies are required to determine whether this abnormality contributes to or results from elevated blood pressure.

Abstract
PURPOSE To perform an external validation of the clinical prediction rule established by Krijnen et al. (Ann Intern Med 1998; 129: 705-11) designed to identify renal artery stenoses (RAS) in hypertensive patients. METHODS We included 102 patients with a refractory hypertension treated with at least two antihypertensive drugs. All subjects had the research of RAS by renal angiography, or angio-computed tomography, or doppler ultrasound. Probability to detect RAS was calculated with Krijnen's algorithm (Pre-test probability) from the following parameters: age, smoking status, diffuse atherosclerosis, recent hypertension (< 2 y), obesity (BMI > 25), abdominal bruit, hypercholesterolemia (> 6.5 mmol/L), creatinine. ROC curves were plotted for each pre-test probability value. A "post-test probability" was obtained from the likelihood ratio calculated at each pre-test probability level. RESULTS RAS prevalence in this population was 49%. Area under the ROC curve was 0.79 and Youden index was maximal for a pre-test probability of 15%. Maximal likelihood ratio was obtained for a pre-test probability of 46%. Table shows post-test probability as a function of pre-test probability obtained with Krijnen's algorithm. [table: see text] CONCLUSION Krijnen's algorithm is valid in a population of resistant hypertensives treated with a bi-therapy. This external validation obtained on a population with a high prevalence of RAS should also be tested on a population with a lower prevalence of SAR.

Abstract
UNLABELLED The aim of this study was to determine the prevalence of secondary hypertension in a population of refractory hypertension without initial clinical or biological findings suggesting identifiable causes of hypertension. METHODS A survey included 200 consecutive hypertensive patients referred to hypertension specialists for refractory hypertension (BP > 140/90 mmHg on at least two antihypertensive drugs). Prior inclusion, the permanent elevation of blood pressure was confirmed by ambulatory monitoring. In each subject an extensive work-up was performed to detect a secondary cause for hypertension. RESULTS An essential hypertension was confirmed in 61% of this cohort. A secondary hypertension was detected in 20% of the patients; 8.5% with a primary hyperaldosteronism, 8% with a reno-vascular hypertension and 3% with a nephropathy. Moreover, 18.5% had a low renin hypertension. Thus, 27% of these patients had an abnormality of the renin-aldosterone axis. CONCLUSION Patients with refractory hypertension should be explored to detect secondary hypertension even without findings suggesting such causes. This additional diagnostic procedure must include at least renovascular investigations and plasma renin/aldosterone level determinations in appropriate conditions.

Abstract
The aim of this study was to provide quantitative data on the origin and trajectory of the main renal arteries using spiral CT angiography and arteriography. Normal renal artery anatomy was assessed on spiral CT angiography (axial transverse sections and shaded-surface-display reconstructions) in 100 patients referred for renal arteriography who had no significant renal artery stenosis. Two hundred major renal arteries were studied. The vast majority of right (88 %) and left (87 %) renal arteries originated between the lower third of the first lumbar vertebra and the lower border of the second lumbar vertebra. In 50 patients both ostia were at the same level; in the remaining 50 patients, the right ostium was located above the left in 37 patients. On the right, the angle of origin varied from -10 to + 55 degrees (mean + 24 degrees ). On the left, the angle of origin varied from + 30 to -55 degrees (mean -11 degrees ). Spiral CT angiography provides additional anatomic data, notably regarding the angle of origin of the renal arteries, that is potentially useful for planning interventional procedures.

Abstract
UNLABELLED A MAJOR CONCERN: Hypertensive syndromes occur in approximately 10 to 15% of all pregnancies and are the cause of 30% of maternal deaths and 20% of fetal and neonatal deaths. Syndromes include gestational hypertension also called pregnancy-induced hypertension, chronic hypertension and preeclampsia. DEFINITION In pregnant women, hypertension is defined as blood pressure levels above 140/90 mmHg at two successive measurements at a 4-hour interval. The primum movens is the development, at about 16 weeks gestation, of secondary placental ischemia due to a defect in the second trophoblastic invasion of the spiral arteries of the myometrium. This induces endothelial dysfunction leading to pro-coagulation activation and inhibited physiological vasodilatation. RISK FACTORS The risk of vasculoplacental disease increases with age, body mass index, primiparity, stressful working conditions, and personal history of vascular events during pregnancy. MATERNAL RISKS Maternal complications include preeclampsia-eclampsia, retroplacental hematoma, acute renal failure, and HELLP syndrome (hemolysis, elevated liver enzymes, low platelet count). FETAL RISKS Hypotrophy, in utero death and prematurity may occur. The development of hypertension during pregnancy may also reveal a hypertensive background which could progress to persistent high blood pressure. Preeclampsia is an independent risk factor of cardiovascular disease requiring regular surveillance after delivery.
