[VIVOPTIM: Feedback of an e-Health experimental program of primary prevention of cardiovascular risk on 30 to 70 years old volunteers]. / VIVOPTIM : retour d'expérience d'un programme expérimental de e-santé et de prévention primaire du risque cardiovasculaire global chez des sujets volontaires âgés de 30 à 70 ans.

Today by the e-health and the telemedicine, many people are more and more interested by the improvement of disease knowledge on cardiovascular diseases and associated risk factors, personalized self management support follow-up and e-Health monitoring. MGEN is a not-for-profit complementary health insurance gave itself the ways to use the new digital tools in health. MGEN developed an original and personalized program VIVOPTIM for the primary prevention of the cardiovascular risks for their members. The VIVOPTIM Pilot program is based upon digital services and was experimented by November 2015 to December, 2017 with 8000 members of the MGEN, from 30 to 70 years old and resident in two French areas (Occitanie and Bourgogne Franche-Comté). The assessment of the experiment VIVOPTIM e -health program was positive for the personalized cardiovascular support and for their health. Therefore, the MGEN generalized the VIVOPTIM program of cardiovascular prevention, to the whole France on July 11th, 2018.

The ambulatory hypotensive effect of aerobic training: a reappraisal through a meta-analysis of selected moderators.

The effectiveness of regular exercise in decreasing both systolic and diastolic blood pressure (BP) is well-established. Our purpose was to assess the impact of both subject and physical activity program characteristics on ambulatory BP through a meta-analysis of the existing literature. Three databases (PubMed, Embase, Web of Science) were searched using relevant terms and strategies. From 637 identified records, 37 studies met inclusion criteria: details about training intervention and participant characteristics, pre- and post-training ambulatory BP measurements, at home (HBPM) or during 24-h (ABPM). The weighted mean difference was for 24-h systolic/diastolic ABPM (n = 847 participants): -4.06/-2.77 mmHg (95%CI: -5.19 to -2.93/-3.58 to -1.97; P < 0.001), for daytime (ABPM or HBPM, n = 983): -3.78/-2.73 mmHg (95%CI: -5.09 to -2.47/-3.57 to -1.89; P < 0.001) and nighttime ABPM periods (n = 796): -2.35/-1.70 mmHg (95%CI: -3.26 to -1.44/-2.45 to -0.95; P < 0.001). Characteristics significantly influencing BP improvement were: an initial office BP ≥130/85 mmHg and diet-induced weight-loss. We found no differences according to sex, age, or training characteristics (intensity, number of sessions, training duration). Antihypertensive effects of aerobic training assessed by ambulatory BP measurements appear significant and clinically relevant for both daytime and nighttime periods, in particular for participants with an office BP ≥130/85 mmHg.

Sex hormone levels are not associated with progression of renal disease in male patients with T2DM.

BACKGROUND: Greater renal function decline (RFD) in type 2 diabetes (T2DM) has been suggested in men compared with women, and imbalances in estrogen/androgen levels have been associated with cardiovascular disease mortality in elderly men, but it remains unclear whether sex hormone disequilibrium is related to diabetic nephropathy (DN) in men with T2DM. OBJECTIVE: This study examined the relationship between sex steroid concentrations and renal outcomes in male T2DM patients. POPULATION AND METHODS: Total testosterone (T), total estradiol (E2), sex hormone-binding globulin (SHBG), and total and calculated free (cf) E2/T ratios were compared in 735 male T2DM patients with (n=513) and without (n=222) DN, using a cross-sectional approach. Also, in a pilot complementary prospective nested case-control cohort, total E2/total T and cfE2/cfT were evaluated according to a hard renal outcome (HRO): end-stage renal disease/doubling of baseline serum creatinine (36 HRO cases, 72 HRO controls) and rate of eGFR decline (68 rapid vs 68 slow RFD). RESULT: With the cross-sectional approach, E2 and cfE2 were higher in DN cases vs DN controls (95.5 vs 86.8pmol/L [P=0.0246] and 2.59 vs 2.36pmol/L [P=0.005], respectively). The difference in E2 persisted on multivariate analysis. In the prospective approach, E2 and T concentrations, and total E2/total T and cfE2/cfT2 ratios did not differ in HRO cases vs controls or in patients with rapid vs slow RFD. CONCLUSION: Although positively related to DN in the cross-sectional analysis, progression of renal disease in male patients with T2DM was not related to either sex hormone levels or aromatase index as reflected by E2/T ratio.

[Physical activity level and home blood pressure measurement: Pilot study "Acti-HTA"]. / Niveau d'activité physique et contrôle ambulatoire de l'hypertension artérielle. Résultats de l'étude pilote « Acti-HTA ¼.

While physical activity (PA) is recommended for high blood pressure management, the level of PA practice of hypertensive patients remains unclear. We aimed to assess the association between the level of both PA and blood pressure of individuals consulting in 9 hypertension specialist centres. Eighty-five hypertensive patients were included (59 ± 14 years, 61% men, 12% smokers, 29% with diabetes). Following their consultation, they performed home blood pressure measurement (HBPM) over 7 days (2 in the morning+2 in the evening), they wrote in a dedicated form their daily activities to estimate the additional caloric expenditure using Acti-MET device (built from International physical Activity Questionnaire [IPAQ]). Thus, patients completed a self-administered questionnaire "score of Dijon" (distinguishing active subjects with a score>20/30, from sedentary<10/30). Subjects with normal HBPM value (<135/85 mm Hg) (55% of them) compared to those with high HBPM were older, had a non-significant trend towards higher weekly caloric expenditure (4959 ± 5045 kcal/week vs. 4048 ± 4199 kcal/week, P=0.3755) and score of Dijon (19.44 ± 5.81 vs. 18.00 ± 4.32, P=0.2094) with a higher proportion of "active" subjects (48.9% vs. 34.2%, P=0.1773). In conclusion, our results demonstrate a "tendency" to a higher level of reported PA for subjects whose hypertension was controlled. This encourages us to continue with a study that would include more subjects, which would assess PA level using an objective method such as wearing an accelerometer sensor.

[High blood pressure and physical exercise]. / Hypertension artérielle et exercice physique - Mise au point pratique.

High blood pressure is a frequent pathology with many cardiovascular complications. As highlighted in guidelines, the therapeutic management of hypertension relies on non-pharmacological measures, which are diet and regular physical activity, but both patients and physicians are reluctant to physical activity prescription. To acquire the conviction that physical activity is beneficial, necessary and possible, we can take into account some fundamental and clinical studies, as well as the feedback of our clinical practice. Physical inactivity is a major risk factor for cardiovascular morbidity and mortality, and hypertension contributes to increase this risk. Conversely, regular practice of physical activity decreases very significantly the risk by up to 60%. The acute blood pressure changes during exercise and post-exercise hypotension differs according to the dynamic component (endurance or aerobic and/or strength exercises), but the repetition of the sessions leads to the chronic hypotensive benefit of physical activity. Moreover, physical activity prescription must take into account the assessment of global cardiovascular risk, the control of the hypertension, and the opportunities and desires of the patient in order to promote good adherence and beneficial lifestyle change.

The influence of sex on renal function decline in people with Type 2 diabetes.

AIMS: Several reports have suggested a relationship between male sex and albuminuria in Type 2 diabetes, but impact on renal function decline has not been established. Our aim was to describe the influence of sex on renal function decline in Type 2 diabetes. METHODS: SURDIAGENE, an inception cohort, consisted in 1470 people with Type 2 diabetes. Patients without renal replacement therapy and with ≥ 3 serum creatinine determinations during follow-up prior to end-stage renal disease were included in the study. Estimated glomerular filtration rate was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation. Primary outcome was steep estimated glomerular filtration rate (eGFR) decline, defined as a yearly slope value lower than -3.5 ml min(-1) 1.73 m(-2). Secondary outcomes were estimated glomerular filtration rate trajectories according to sex and occurrence of end-stage renal disease. RESULTS: A total of 22 914 serum creatinine determinations were considered in 1146 participants (60% men), aged 65 ± 11 years, with a median follow-up duration of 5.7 years (range 0.1-10.2). Median yearly estimated glomerular filtration rate slope was -1.31 ml min(-1) 1.73 m(-2) in women and -1.77 ml min(-1) 1.73 m(-2) in men (P < 0.001). Men were more likely than women to develop end-stage renal disease (22 men vs. 7 women; P(log-rank) = 0.03). Male sex was an independent risk factor of steep estimated glomerular filtration rate decline [adjusted odds ratio = 1.33 (1.02-1.76), P = 0.04] after adjustment for age, time from diagnosis of Type 2 diabetes, glycated haemoglobin, systolic blood pressure and urinary albumin:creatinine ratio. A multivariable linear mixed-effects model showed a significant difference of estimated glomerular filtration rate trajectories between men and women (P < 0.001). CONCLUSION: Male sex is an important independent factor associated with renal function decline in Type 2 diabetes.

[Smokeless tobacco and cardiovascular risk]. / Snus et risque cardiovasculaire.

The use of "snus" (smokeless tobacco) can be detrimental to health. Snus delivers rapidly high doses of nicotine which can lead to addiction. The use of snus increases the risk of myocardial infarction and stroke. Nicotine substitution therapy as well as bupropion and varenicline reduce withdrawal symptoms and tobacco craving during snus cessation. However, they have been shown not to assist in long-term abstinence. Information concerning potential cardiovascular hazards of snus must be incorporated into health educational programs in order to discourage its use. Snus is not a recommended product to help stop smoking.

[Treatment of homozygous familial hypercholesterolemia with LDL-apheresis on a 4-year-old child]. / Traitement d'une hypercholestérolémie familiale homozygote par LDL-aphérèse chez un enfant de 4 ans.

Homozygous familial hypercholesterolemia (HFH) is a rare genetic disease associated with increased atherosclerosis, resulting in premature death near the age of 20 years. Treatment requires the LDL-apheresis system. M, born from a consanguineous union, suffers from HFH (total-cholesterol=12.29 g/l, LDL-cholesterol=9.65 g/l). Diet and drug treatment was not associated with decreased LDL-cholesterol. At the age of 4.5 years (body weight: 16.7 kg), M began treatment with LDL-apheresis. Apheresis treatment was given every 2 weeks using the Direct Adsorption of LIpoprotein (DALI system, a process that involves total-blood filtration. During the first 26 sessions, the mean reduction in LDL-cholesterol was 67+/-12%, while HDL-cholesterol decreased by only 17+/-11%. Mean LDL-cholesterol concentration decreased from 6.54+/-0.93 g/l (before apheresis) to 2.21+/-0.95 g/l (after apheresis). Apart from iron deficiency anemia, no major side effects were observed. LDL-apheresis using the DALI system is associated with significant reductions in LDL-cholesterol (similar to reports from the literature) without major side effects, even in a child weighing less than 20 kg. A long term, multinational (European) study is needed to confirm these results.

Management in general practice of hypertensive patients poorly controlled with a fixed-dose renin-angiotensin system inhibitor and diuretic combination: results from a French national survey.

High rates of uncontrolled hypertensives have been reported in France as well as in other countries, partly owing to an inadequate management of hypertension by clinicians. The objectives of the study were (1) to describe the therapeutic decisions faced by general practitioners (GP) in hypertensives not controlled by fixed-dose combination antihypertensive therapy with a renin-angiotensin system (RAS) inhibitor and a diuretic (D) and (2) to evaluate the frequency with which ambulatory blood pressure monitoring (ABPM) is used in these patients. Each GP had to include five uncontrolled hypertensives on fixed-dose RAS inhibitor and D combination. A total of 2118 GPs included 9551 patients; 8643 patients were receiving at least one of the two drugs at a low dose (group 1) and the remaining 908 patients were receiving high doses of both drugs (group 2). The most common therapeutic choice was that of a new combination, either a fixed-dose in one pill or with separate preparations: 65% (n=5621) in group 1 and 56% (n=505) in group 2. An increase in dose was chosen in 28% of patients in group 1 (n=2467) and continuation of treatment without modification in 27% of patients in group 2 (n=242). A third active principle was only added in 2.5% of patients in group 1 (n=219) and 11% in group 2 (n=103). Ambulatory blood pressure monitoring was employed in 25% of patients (n=2413). An improvement in hypertension management should be expected from the implementation of the 2005 French guidelines.

Determination of HbA1c concentrations in patients with acute myocardial infarction: comparison of the DCA 2000 device with the HPLC method.

BACKGROUND: Recent studies suggest that HbA1c is an important predictor of the glycometabolic state of patients admitted for acute myocardial infarction (AMI). OBJECTIVE: We aimed at comparing the results of HbA1c concentrations obtained by 2 different methods in patients with AMI. RESEARCH DESIGN AND METHODS: In a first study, HbA1c was measured in all patients consecutively hospitalized for AMI, during a 6 month period using the HPLC method and the DCA 2000 device in the biochemistry laboratory. In a second study, HbA1c measured by the DCA 2000 device in the intensive care unit was compared with HbA1c determined by HPLC in the biochemistry laboratory in a similar sample of patients. In patients without personal history of diabetes, those patients with HbA1c > 6.5% (HPLC method), were classified as possible diabetes. RESULTS: A total of 146 patients were included (119 males, 27 females; mean age: 63 +/- 15 years). Twenty-seven of the patients had a personal history of diabetes. HbA1c determined by 2 techniques were highly correlated (r = 0.939, P < 0.0001). The mean of the differences (Bland and Altman analysis) was 0.4 +/- 0.3%. Compared with the HPLC method, the sensitivity of DCA 2000 device for the detection of possible diabetes was 81.8 +/- 11.6 and the specificity was 99.1 +/- 0.9%. The diagnostic accuracy of DCA method was 97.5 +/- 1.4%. In the second study, the HbA1c concentrations of 21 additional subjects, determined in an intensive care unit, were not different from the first 21 patients of the first study. CONCLUSIONS: HbA1c can be effectively determined using the DCA 2000 device. This method is reliable and easy to be implemented in an intensive care unit.

Appraisal of the knowledge of hypertensive patients and assessment of the role of the pharmacists in the management of hypertension: results of a regional survey.

The objectives of the study were to appraise the knowledge which the patients have about their hypertension, and to assess the knowledge and involvement of pharmacists in the management of the hypertensive patient. All the pharmacies in the Poitou-Charentes area were invited both to participate in a training session about arterial hypertension and asked to fill in a pharmacist's questionnaire. Furthermore, each participant was required to submit a patient's questionnaire to 20 consecutive hypertensives. A total of 104 pharmacies and 1015 hypertensive patients participated in the survey. In all, 88% of the patients (n = 893) were aware of their blood pressure (BP) figures, but 68% (349/515) considered themselves wrongly, to be normalized; 39% (n = 350) only had BP figures <140/90 mmHg. They said they had been poorly informed about recommended lifestyle changes. In all, 18% (n = 185) were equipped with an automatic device. A total of 77% (n = 779) were able to give the names of their drugs without the help of the pharmacist. Treatment-related unwanted effects were reported by 8% of the patients (n = 79). Only 18% (n = 29) of the pharmacists were able to provide a correct definition of hypertension. Most of them thought hypertension was well controlled in the general population and considered that both tolerance of and compliance with antihypertensive treatment were satisfactory. They could most often (80%, n = 135) supply a SBPM device, but 58 (36%) only were able to provide relevant advice regarding the recommended procedures. In conclusion, The BP goals and the lifestyle modifications are poorly known by the hypertensives. Pharmacists' knowledge is frequently wrong and should be improved by appropriate training programmes.

Prognostic value of admission plasma glucose and HbA in acute myocardial infarction.

OBJECTIVE: Stress hyperglycaemia increases the risk of mortality after acute myocardial infarction in diabetic and in non-diabetic patients. We aimed to determine the contribution of admission plasma glucose and HbA(1c) on post-acute myocardial infarction prognosis. PATIENTS AND METHODS: Admission plasma glucose and HbA(1c) were simultaneously measured in all patients consecutively hospitalized for acute myocardial infarction. Patient survival was measured on 5 and 28 days after admission. Patients were defined as having 'previously diagnosed diabetes' (personal history of diabetes defined using ADA 1997 criteria), 'no diabetes', those without previously diagnosed diabetes and HbA(1c) below 6.5%, or 'possible diabetes', i.e. those without previously diagnosed diabetes and HbA(1c) above 6.5%. RESULTS: Of the 146 patients included, four had died by day 5 and 14 by day 28. Admission plasma glucose was higher in patients who had died by day 28 (11.7 +/- 5.8 vs. 8.0 +/- 3.3 mmol/l, P = 0.002), whereas HbA(1c) was not (6.4 +/- 1.9 vs. 6.1 +/- 0.8%, NS). Admission plasma glucose was significantly higher in those who had died by day 28 after adjustment on HbA(1c). A multivariate analysis, including sex, age and heart failure prior to acute myocardial infarction, showed that admission plasma glucose concentration was an independent predictor of survival after acute myocardial infarction. Twenty-seven of the patients had previously diagnosed diabetes and 119 had no history of diabetes. Eleven were found to have possible diabetes. Admission plasma glucose was significantly higher in previously diagnosed diabetes (11.1 +/- 5.6) than in the other groups: 7.7 +/- 2.9 in non-diabetes, 8.2 +/- 2.1 in possible diabetes (P < 0.0001). The relationship between HbA(1c)-adjusted admission plasma glucose and mortality after acute myocardial infarction was also found in the non-diabetes group. CONCLUSIONS: Admission plasma glucose, even after adjustment on HbA(1c), is a prognostic factor associated with mortality after acute myocardial infarction. Acute rather than the chronic pre-existing glycometabolic state accounts for the prognosis after acute myocardial infarction.

[Investigation of hyperaldosteronism in the hypertensive patient. Why? When? How?]. / Recherche d'un hyperaldostéronisme primaire chez l'hypertendu. Pourquoi? Quand? Comment?

Primary aldosteronism (PA) has been regarded for a long time as being a rare cause of arterial hypertension, but its prevalence has recently been reassessed as about 10%. This etiology should obviously be sought in the following settings: hypertension associated with hypokaliemia < 3.6 mmol/L (or < 3.9 mmol/L on ACE inhibitors): refractory hypertension: severe hypertension occurring before 40 years of age, especially in women. It must be reminded that more than 20% of PA are normokaliemic. Most of the authors recommend to use the aldosterone/renin ratio (ARR) as a screening test within these selected patients. When ARR turns out to be equal to or higher than 23 (if aldosterone and renin are given in pg/mL or ng/L), a suppression testing should be performed, using salt loading and/or fludrocortisone. Computed tomography scanning yields a specificity of 58% and a positive predictive value of 72%, only. Adenoma and hyperplasia have to be distinguished, using either NP-59 scintigraphy or adrenal venous samplings. Such a strategy appears to be useful, for the following reasons: removal of an adenoma results in a significant blood pressure lowering and in a blood pressure normalization in 95% and in 32% of the patients, respectively; in patients with hyperplasia, spironolactone therapy is followed by a 20% mean reduction in blood pressure.

Obstructive intramural coronary amyloidosis and papillary muscle rupture.

Mitral papillary muscle rupture is usually caused by ischaemia as a complication of myocardial infarction. In a 76 year old patient with no significant disease or major cardiovascular risk factors, papillary muscle rupture was caused by obstructive intramural coronary amyloidosis, an unusual cause.

[Assessment of the effects of antihypertensive drugs on stress-induced cardiovascular changes]. / Effets des médicaments antihypertenseurs sur les conséquences cardiovasculaires des contraintes physiques et psychosensorielles.

The authors reviewed some of the most relevant studies dedicated to the assessment of the effects of the antihypertensive drugs on the stress-induced cardiovascular changes. The rises in both blood pressure and heart rate turned out not to be significantly altered by calcium channel blockers, ACE inhibitors, moxonidine, nor beta-blockers, whereas they seemed to be slightly blunted by alpha-blocking drugs. However, since baseline blood pressure was significantly lower in treated hypertensives than in placebo-given patients, all antihypertensive drugs eventually resulted in a lower blood pressure level during stress, as compared with untreated patients. Regarding white coat effect, which has to be considered as a very particular stress, it appeared to be lowered to the same extent by placebo and antihypertensive drugs; moreover, its changes were not associated with any clinical beneficial effect.

Clinical and laboratory characteristics of infective endocarditis when associated with spondylodiscitis.

Spondylodiscitis is rarely observed in association with infective endocarditis (IE). In the study presented here, 92 cases of definite IE were examined. Spondylodiscitis was present in 14 (15%) cases. The mean age of patients with spondylodiscitis was 69.1+/-13.6 years (range, 33-87 years). The male-to-female ratio was 8:6. Predisposing heart disease was found in nine (64.3%) cases. Back pain was reported in all cases. Spondylodiscitis was diagnosed before endocarditis in all cases. The infection affected the lumbar spine in 10 (71%) cases. A bacterium was isolated in all cases: group D Streptococcus ( n=5; 35.7%), coagulase-negative Staphylococcus ( n=4; 28.6%), and others ( n=5). Endocarditis affected predominantly the aortic valve (43%). The outcome was favourable in 12 cases. No differences in clinical features, evolution of disease, or laboratory values were found between IE patients with and IE patients without spondylodiscitis. Spondylodiscitis does not appear to worsen prognosis of IE, although the need for cardiac valve replacement seems to be more frequent in IE patients with spondylodiscitis. IE should be included in the differential diagnosis in patients with infectious spondylodiscitis and risk factors for endocarditis. In such patients, echocardiography should be performed routinely.

[Traumatic coronary dissection caused by deceleration. Report of a case]. / Dissection coronaire traumatique par décélération. A propos d'un cas.

Myocardial infarction is a rare complication of traumatic thoracic deceleration. The authors report the case of anterior myocardial infarction with dissection of the left anterior descending artery in a 16 year old boy who was injured in a motorbike accident without a penetrating thoracic wound. Therefore, the only pathological mechanism was deceleration. The authors review the 12 previously reported cases.
