Persistence of uncontrolled hypertension post-cardiac rehabilitation in stable coronary patients.

In stable coronary heart disease, uncontrolled risk factors are strongly associated with incident myocardial infarction. We analysed the management of hypertension in 746 stable coronary patients recruited between 2005 and 2015 in a single-centre prospective study. Risk factors and pharmacological treatments were documented prior to and immediately after cardiac rehabilitation, and 1 year later. One year post-cardiac rehabilitation, all cardiovascular risk factors were significantly better controlled with the notable exception of hypertension: blood pressure (BP) <140/90 mmHg in 60% of the total population vs 49% (N = 450) of hypertensive patients (20% or 10%, according to the ACC/AHA 2017 or ESH/ESC guidelines, respectively). Of those who had achieved normotension by the end of cardiac rehabilitation, 42% had uncontrolled hypertension again 1 year later; in addition, body weight had increased, while physical activity and antihypertensive drug use had dropped (differences between controlled or uncontrolled hypertension at 1 year post-cardiac rehabilitation, NS). Three factors were correlated with BP elevations: discontinuation of betablockade: +7.9 mmHg; age >65 years: +6.2 mmHg; diabetes mellitus: +7.6 mmHg. Only 48% hypertensive patients were on guideline-recommended antihypertensive polytherapy. Although 28% were still hypertensive post-cardiac rehabilitation, and hypertension remained uncontrolled in 70% 1 year later, 61% antihypertensive prescriptions were not adjusted post-cardiac rehabilitation. One year post-cardiac rehabilitation, hypertension was the only cardiovascular risk factor that had not improved. This can be attributed to three main reasons, all associated with BP elevations: precipitous reduction in betablockade, physicians' inertia when faced with uncontrolled hypertension and lack of adherence to international guidelines.

[Expert consensus statement on blood pressure measurement from the French Society of Hypertension, an affiliate of the French Society of Cardiology]. / Recommandations sur la mesure de la pression artérielle. Consensus d'experts de la Société française d'hypertension artérielle, filiale de la Société française de cardiologie.

Since 2016, the French Society of Hypertension has warned about the decline in the management of high blood pressure in France: stagnation, or even decreased number of people who know their blood pressure level, take a treatment and are controlled. These results are lower than those observed in many other countries. Blood pressure is measured with an old method in the doctor's office. Accepted, simple and cost-effective, this method is currently unavoidable for reasons of feasibility and social habit. It has been used in observational and intervention studies that are the basis of the medical reasoning for screening, treatment and drug control of hypertension. In practice, it is too often poorly applied and unpredictable. It is now necessary to measure blood pressure in mmHg using a validated oscillometric automatic device coupled to a specific upper arm cuff adapted to the arm circumferences for the diagnosis and monitoring of high blood pressure in the doctor's office and at home. The auscultatoric measurement is only recommended if any doubt about the reliability of the electronic measurement. Blood pressure measurement is basically performed on both arms to detect asymmetry and then on the arm with the highest blood pressure. It is performed in sitting or lying position after a few minutes of rest without speaking and without having smoked and then in standing position to diagnose orthostatic hypotension, especially in elderly, diabetic and multi-medicated subjects. The blood pressure measurement during the consultation must be repeated and include at least 3 consecutive measurements at one minute intervals. The average of the last 2 measurements determines the blood pressure level. It is recommended to perform BP measurements outside the medical environment for the diagnosis and monitoring of hypertension; Home BP measurement is preferred to ambulatory blood pressure measurement for practical reasons unless otherwise specified. The home blood pressure measurement should include three measurements in the morning at breakfast and three measurements in the evening before bedtime at one minute intervals for at least three days. Prior training must be provided. In treated hypertensive patients, a masked hypertension should be considered as an uncontrolled hypertension and antihypertensive therapy adapted accordingly. The measurement of central BP pressure (aorta) should be limited to clinical research.

[Sexual dysfunction and antihypertensive treatment: Involvement of the different therapeutic classes and what to do about the treatment of hypertension]. / Dysfonction érectile et traitement antihypertenseur : impact des différentes classes thérapeutiques et conduite à tenir à l'égard du traitement.

Erectile dysfunction (ED) is not routinely discussed with patients in cardiology practices whereas it may impact the ability of patients to stay on therapy. Most of the studies about ED and antihypertensive therapies have several methodological limitations. Diuretics and beta-blockers have been shown to have a deleterious effect on ED. ISRA inhibitors, calcium antagonists, vasodilator beta-blockers and alpha-blockers have been shown to have a neutral impact on ED. Angiotensin 2 inhibitors, nebivolol and alpha-blockers use has sometimes beneficial effect on ED. In case of ED due to antihypertensive treatment, drugs can be switched each other but careful attention in patients with a high cardiovascular risk is required.

A pilot double-blind randomized placebo-controlled crossover pharmacodynamic study of the centrally active aminopeptidase A inhibitor, firibastat, in hypertension.

OBJECTIVES: We conducted a pilot multicenter double-blind randomized placebo-controlled crossover pharmacodynamic study to evaluate the blood pressure (BP) and the hormonal effects of firibastat, a first-in-class aminopeptidase A inhibitor prodrug, in patients with hypertension. METHODS: Thirty-four patients with daytime ambulatory BP of at least 135/85 mmHg and less than 170/105 mmHg, after a 2-week run-in period were randomly assigned to receive either firibastat (250 mg b.i.d. for 1 week uptitrated to 500 mg b.i.d. for 3 weeks) and then placebo for 4 weeks each or vice versa, with a 2-week washout period on placebo. RESULTS: At 4 weeks, daytime ambulatory systolic BP (SBP) decreased by 2.7 mmHg (95% confidence interval -6.5 to +1.1 mmHg) with firibastat versus placebo (P = 0.157). Office SBP decreased by 4.7 mmHg (95% confidence interval -11.1 to +1.8 mmHg) with firibastat versus placebo (P = 0.151). However, more the basal daytime ambulatory SBP was elevated, more the firibastat-induced BP decrease was marked. Firibastat did not influence 24h-ambulatory heart rate. Firibastat had no effect on plasma renin, aldosterone, apelin and copeptin concentrations. No major adverse events occurred. There was one episode of reversible skin allergy with facial edema. CONCLUSION: In patients with hypertension, a 4-week treatment with firibastat, tended to decrease daytime SBP relative to placebo. Firibastat did not modify the activity of the systemic renin-angiotensin system These results have justified designing a larger, powered trial of longer duration to fully assess its safety and effectiveness.

Clinic Versus Ambulatory Blood Pressure in Resistant Hypertension: Impact of Antihypertensive Medication Nonadherence: A Post Hoc Analysis the DENERHTN Study.

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.

Is ventilatory therapy combined with exercise training effective in patients with heart failure and sleep-disordered breathing? Results of a randomized trial during a cardiac rehabilitation programme (SATELIT-HF).

BACKGROUND: Sleep-related disordered breathing is common in patients with chronic heart failure. AIM: To assess the efficacy of short-term nocturnal ventilatory therapy combined with exercise training (V+ET) compared with exercise training alone (ET) in patients with chronic heart failure with sleep-disordered breathing. METHODS: Patients in New York Heart Association functional class II-IIIb, with an apnoea-hypopnoea index (AHI)>15/h, and enrolled in a cardiac rehabilitation programme, were centrally randomized to V+ET or ET. Subjects were classified as having obstructive sleep apnoea (OSA) (n=49) or central sleep apnoea (CSA)/mixed (n=69). The primary outcome was the change in the 10-second average oxygen consumption at maximum exercise (VO2peak) at the end of the cardiac rehabilitation programme. RESULTS: Fifty-eight patients were randomized to V+ET and 60 patients to ET. The median increase in VO2peak was 15% [interquartile range 6-36%] in the V+ET group and 16% [0-31%] in the ET group (P=0.34). AHI decreased in both groups, but significantly more in the V+ET group (P=0.006). The decrease in the ventilatory efficiency (VE/VCO2) slope was not statistically different between the two-randomization groups (P=0.10). In subjects with CSA, the VE/VCO2 slope decreased significantly more in the V+ET group (P=0.03), while there was no difference between the two-randomization groups in subjects with OSA (P=0.75). Six cardiovascular events occurred in patients with OSA (all randomized to the ET group); in subjects with CSA, two events occurred in the V+ET group and three in the ET group. CONCLUSIONS: Short-term nocturnal ventilation combined with exercise training does not increase the exercise capacity of patients with chronic heart failure.

Abdominal Aortic Calcifications Influences the Systemic and Renal Hemodynamic Response to Renal Denervation in the DENERHTN (Renal Denervation for Hypertension) Trial.

BACKGROUND: The DENERHTN (Renal Denervation for Hypertension) trial confirmed the efficacy of renal denervation (RDN) in lowering daytime ambulatory systolic blood pressure when added to standardized stepped-care antihypertensive treatment (SSAHT) for resistant hypertension at 6 months. METHODS AND RESULTS: This post hoc exploratory analysis assessed the impact of abdominal aortic calcifications (AAC) on the hemodynamic and renal response to RDN at 6 months. In total, 106 patients with resistant hypertension were randomly assigned to RDN plus SSAHT or to the same SSAHT alone (control group). Total AAC volume was measured, with semiautomatic software and blind to randomization, from the aortic hiatus to the iliac bifurcation using the prerandomization noncontrast abdominal computed tomography scans of 90 patients. Measurements were expressed as tertiles. The baseline-adjusted difference in the change in daytime ambulatory systolic blood pressure from baseline to 6 months between the RDN and control groups was -10.1 mm Hg (P=0.0462) in the lowest tertile and -2.5 mm Hg (P=0.4987) in the 2 highest tertiles of AAC volume. Estimated glomerular filtration rate remained stable at 6 months for the patients in the lowest tertile of AAC volume who underwent RDN (+2.5 mL/min per 1.73 m2) but decreased in the control group (-8.0 mL/min per 1.73 m2, P=0.0148). In the 2 highest tertiles of AAC volume, estimated glomerular filtration rate decreased similarly in the RDN and control groups (P=0.2640). CONCLUSIONS: RDN plus SSAHT resulted in a larger decrease in daytime ambulatory systolic blood pressure than SSAHT alone in patients with a lower AAC burden than in those with a higher AAC burden. This larger decrease in daytime ambulatory systolic blood pressure was not associated with a decrease in estimated glomerular filtration rate.

Twenty-Four-Hour Blood Pressure Monitoring to Predict and Assess Impact of Renal Denervation: The DENERHTN Study (Renal Denervation for Hypertension).

The DENERHTN trial (Renal Denervation for Hypertension) confirmed the blood pressure (BP) lowering efficacy of renal denervation added to a standardized stepped-care antihypertensive treatment for resistant hypertension at 6 months. We report here the effect of denervation on 24-hour BP and its variability and look for parameters that predicted the BP response. Patients with resistant hypertension were randomly assigned to denervation plus stepped-care treatment or treatment alone (control). Average and standard deviation of 24-hour, daytime, and nighttime BP and the smoothness index were calculated on recordings performed at randomization and 6 months. Responders were defined as a 6-month 24-hour systolic BP reduction ≥20 mm Hg. Analyses were performed on the per-protocol population. The significantly greater BP reduction in the denervation group was associated with a higher smoothness index (P=0.02). Variability of 24-hour, daytime, and nighttime BP did not change significantly from baseline to 6 months in both groups. The number of responders was greater in the denervation (20/44, 44.5%) than in the control group (11/53, 20.8%; P=0.01). In the discriminant analysis, baseline average nighttime systolic BP and standard deviation were significant predictors of the systolic BP response in the denervation group only, allowing adequate responder classification of 70% of the patients. Our results show that denervation lowers ambulatory BP homogeneously over 24 hours in patients with resistant hypertension and suggest that nighttime systolic BP and variability are predictors of the BP response to denervation.

Hypertension and pregnancy: expert consensus statement from the French Society of Hypertension, an affiliate of the French Society of Cardiology.

High blood pressure in pregnancy remains, by its complications, the leading cause of morbidity as well as maternal and fetal mortality. The frequency (5-10% of pregnancies) and the potential severity of this disease, for both mother and child, encourage to standardize and to optimize our medical practices. If the short-term complications for the mother and child are well known, long-term ones for the mother are beginning to be better identified. The onset of hypertension during pregnancy disrupts the classic organization of health care and requires the intervention of the general practitioner and/or an obstetrician, a gynecologist, a midwife, a cardiologist, a nephrologist. There is not always a care coordinator, and decisions are sometimes taken with delay. This is what drove the French Society of Hypertension, in partnership with the French National College of Gynecologists-Obstetricians, to develop a consensus proposing easy-to-use guidelines. Educating women and all health professionals to hypertension and its management, in line with current scientific data, is one of the major challenges of this consensus.

Adherence to Antihypertensive Treatment and the Blood Pressure-Lowering Effects of Renal Denervation in the Renal Denervation for Hypertension (DENERHTN) Trial.

BACKGROUND: The DENERHTN trial (Renal Denervation for Hypertension) confirmed the blood pressure-lowering efficacy of renal denervation added to a standardized stepped-care antihypertensive treatment for resistant hypertension at 6 months. We report the influence of adherence to antihypertensive treatment on blood pressure control. METHODS: One hundred six patients with hypertension resistant to 4 weeks of treatment with indapamide 1.5 mg/d, ramipril 10 mg/d (or irbesartan 300 mg/d), and amlodipine 10 mg/d were randomly assigned to renal denervation plus standardized stepped-care antihypertensive treatment, or the same antihypertensive treatment alone. For standardized stepped-care antihypertensive treatment, spironolactone 25 mg/d, bisoprolol 10 mg/d, prazosin 5 mg/d, and rilmenidine 1 mg/d were sequentially added at monthly visits if home blood pressure was ≥135/85 mm Hg after randomization. We assessed adherence to antihypertensive treatment at 6 months by drug screening in urine/plasma samples from 85 patients. RESULTS: The numbers of fully adherent (20/40 versus 21/45), partially nonadherent (13/40 versus 20/45), or completely nonadherent patients (7/40 versus 4/45) to antihypertensive treatment were not different in the renal denervation and the control groups, respectively (P=0.3605). The difference in the change in daytime ambulatory systolic blood pressure from baseline to 6 months between the 2 groups was -6.7 mm Hg (P=0.0461) in fully adherent and -7.8 mm Hg (P=0.0996) in nonadherent (partially nonadherent plus completely nonadherent) patients. The between-patient variability of daytime ambulatory systolic blood pressure was greater for nonadherent than for fully adherent patients. CONCLUSIONS: In the DENERHTN trial, the prevalence of nonadherence to antihypertensive drugs at 6 months was high (≈50%) but not different in the renal denervation and control groups. Regardless of adherence to treatment, renal denervation plus standardized stepped-care antihypertensive treatment resulted in a greater decrease in blood pressure than standardized stepped-care antihypertensive treatment alone.

High blood pressure in pregnancy remains, by its complications, the leading cause of morbidity and maternal and fetal mortality. The frequency (5 to 10% of pregnancies) and the potential severity of this disease, both for mother and child, encourage to standardize and to optimize our medical practices. This is the main objective of this work. If the short-term complications for the mother and child are well known, long-term ones for the mother beginning to be better identified (in particular, the risk of recurrence in a subsequent pregnancy, the risk of chronic hypertension and the increased risk of cardiovascular events). The occurrence of hypertension during pregnancy disturbs the "classic" organization of care. Several health professionals are involved, the general practitioner, obstetrician, gynecologist, midwife, cardiologist, nephrologist… There is not always a care coordinator and decisions are sometimes taken with delay. These data encouraged the French Society of Hypertension to write a consensus offering easy and efficient recommendations. Educate women and all health professionals to hypertension and its management, in line with current scientific data, is one of the major challenges of this consensus.

[Methods of blood pressure measurement during pregnancy]. / Méthodes de mesure de la pression artérielle pendant la grossesse.

Hypertension during pregnancy is associated with high perinatal morbidity and mortality. The prevalence of white coat hypertension is high during pregnancy and is associated with a good prognosis and must be excluded. The definition of hypertension during pregnancy is office BP≥140/90mmHg and ≥135/85mmHg with home BP and diurnal ambulatory BP. How to use HBPM during pregnancy? To get an adapted and validated BP humeral device during pregnancy; to use it in good conditions with the "3 rules". When to use HBPM during pregnancy? To confirm the diagnosis of hypertension; to monitor BP during pregnancy and to alert the obstetrician when severe hypertension occurs; to manage BP treatment and avoid excessive treatment. HBP and ABP monitoring may be used to exclude white coat effect but HBPM must be preferred when prolonged use.

Optimum and stepped care standardised antihypertensive treatment with or without renal denervation for resistant hypertension (DENERHTN): a multicentre, open-label, randomised controlled trial.

BACKGROUND: Conflicting blood pressure-lowering effects of catheter-based renal artery denervation have been reported in patients with resistant hypertension. We compared the ambulatory blood pressure-lowering efficacy and safety of radiofrequency-based renal denervation added to a standardised stepped-care antihypertensive treatment (SSAHT) with the same SSAHT alone in patients with resistant hypertension. METHODS: The Renal Denervation for Hypertension (DENERHTN) trial was a prospective, open-label randomised controlled trial with blinded endpoint evaluation in patients with resistant hypertension, done in 15 French tertiary care centres specialised in hypertension management. Eligible patients aged 18-75 years received indapamide 1·5 mg, ramipril 10 mg (or irbesartan 300 mg), and amlodipine 10 mg daily for 4 weeks to confirm treatment resistance by ambulatory blood pressure monitoring before randomisation. Patients were then randomly assigned (1:1) to receive either renal denervation plus an SSAHT regimen (renal denervation group) or the same SSAHT alone (control group). The randomisation sequence was generated by computer, and stratified by centres. For SSAHT, after randomisation, spironolactone 25 mg per day, bisoprolol 10 mg per day, prazosin 5 mg per day, and rilmenidine 1 mg per day were sequentially added from months two to five in both groups if home blood pressure was more than or equal to 135/85 mm Hg. The primary endpoint was the mean change in daytime systolic blood pressure from baseline to 6 months as assessed by ambulatory blood pressure monitoring. The primary endpoint was analysed blindly. The safety outcomes were the incidence of acute adverse events of the renal denervation procedure and the change in estimated glomerular filtration rate from baseline to 6 months. This trial is registered with ClinicalTrials.gov, number NCT01570777. FINDINGS: Between May 22, 2012, and Oct 14, 2013, 1416 patients were screened for eligibility, 106 of those were randomly assigned to treatment (53 patients in each group, intention-to-treat population) and 101 analysed because of patients with missing endpoints (48 in the renal denervation group, 53 in the control group, modified intention-to-treat population). The mean change in daytime ambulatory systolic blood pressure at 6 months was -15·8 mm Hg (95% CI -19·7 to -11·9) in the renal denervation group and -9·9 mm Hg (-13·6 to -6·2) in the group receiving SSAHT alone, a baseline-adjusted difference of -5·9 mm Hg (-11·3 to -0·5; p=0·0329). The number of antihypertensive drugs and drug-adherence at 6 months were similar between the two groups. Three minor renal denervation-related adverse events were noted (lumbar pain in two patients and mild groin haematoma in one patient). A mild and similar decrease in estimated glomerular filtration rate from baseline to 6 months was observed in both groups. INTERPRETATION: In patients with well defined resistant hypertension, renal denervation plus an SSAHT decreases ambulatory blood pressure more than the same SSAHT alone at 6 months. This additional blood pressure lowering effect may contribute to a reduction in cardiovascular morbidity if maintained in the long term after renal denervation. FUNDING: French Ministry of Health.

[Management of resistant hypertension. Expert consensus statement from the French Society of Hypertension, an affiliate of the French Society of Cardiology]. / Prise en charge de l'hypertension artérielle résistante. Consensus d'experts de la Société française d'hypertension artérielle, filiale de la Société française de cardiologie.

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 which is easily applicable to daily clinical practice for health professionals working within the French health system. Resistant hypertension is defined as uncontrolled blood pressure (BP) both 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 four weeks, at optimal doses. Treatment compliance must be closely monitored, as most factors that are likely to affect treatment resistance (excessive dietary salt intake, alcohol, depression and drug interactions, or vasopressors). 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 to 25mg/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.

[Home blood pressure measurement and pregnancy]. / Automesure de la pression artérielle et grossesse.

Hypertension during pregnancy is associated with high perinatal morbidity and mortality The prevalence of white coat hypertension is high during pregnancy and is associated with a good prognosis. This must be excluded before beginning antihypertensive treatment. When to use HBPM during pregnancy? To confirm the diagnosis of hypertension; to monitor BP during pregnancy and to alert the obstetrician when severe hypertension occurs; to manage BP treatment and avoid excessive treatment. How to use HBPM during pregnancy? To get an adapted and validated BP device during pregnancy; to compare the results with reference HBP values during the 3 trimesters of pregnancy. Telemetry to monitor BP at home during pregnancy is a feasible, safe and well-tolerated alternative to repeated clinic visits or BP monitoring during hospitalisations.

Impact of miscuffing during home blood pressure measurement on the prevalence of masked hypertension.

BACKGROUND: Masked hypertension has been associated with obesity. However, because most studies do not mention the specific cuff size used for home measurements, masked hypertension prevalence may have been overestimated in obese patients because of undersized cuffs. In this prospective, observational study, the effect of miscuffing on hypertension status was evaluated in patients with large arms. METHODS: Fifty-three patients with an upper-arm circumference >33cm, undergoing treatment for mild-to-moderate hypertension, took 2 sets of home blood pressure (BP) measurements (standard vs. large cuff) using the validated Microlife BP A100 Plus automated device. RESULTS: Mean BP was 143/85mm Hg at the office using a large cuff, 141/84mm Hg at home using a standard cuff, and 134/80mm Hg at home using a large cuff. Standard vs. large cuff home BP mean differences were 6.9mm Hg (95% confidence interval (CI) = 4.7-9.2; P < 0.0001) for systolic BP and 4.0mm Hg (95% CI = 2.4-5.5; P < 0.0001) for diastolic BP. Hypertension status differed significantly between standard vs. large cuffs: sustained hypertension (56.6% vs. 41.5%, respectively; P = 0.002), controlled hypertension (20.8% vs. 28.3%, respectively; P = 0.04), white coat hypertension (7.5% vs. 22.6%, respectively; P = 0.002), masked hypertension (15.1% vs. 7.5%, respectively; P = 0.04). CONCLUSIONS: In patients with large arms, use of an appropriately sized large cuff for home BP measurements led to a 2-fold reduction in masked hypertension. Regarding clinical and epidemiological implications, future studies investigating masked hypertension should specify cuff size for home BP measurements. The low market availability and increased cost of large cuffs should also be addressed.

Diagnosis of white coat hypertension in pregnant women with teletransmitted home blood pressure.

OBJECTIVES: To assess the diagnosis and prognosis of white coat hypertension (WCH) as detected by home blood pressure (HBP) monitoring measured telemetrically in pregnant women with recently discovered hypertension. METHODS: 57 women evaluated using HBP monitoring. RESULTS: The prevalence of WCH was high (76%). Telemetry was necessary as obstetricians were alerted for 8.8% of women. Birth weight was higher in infants born to women with WCH (3571 g vs. 3045 g, p = 0.05). Ninety-eight percent of HBP results were validated. 92% of the women found HBP monitoring to be very easy. CONCLUSION: In this population, WCH is very common and benign. HBP monitoring is feasible and well accepted. However, teletransmission is necessary for safety.

A specific training on hypertension guidelines improves blood pressure control by more than 10% in hypertensive patients: the VALNORM study.

VALNORM was designed to assess the impact on blood pressure (BP) control of a specific training in new European Society of Hypertension-International Society of Hypertension (ESH-ISH) guidelines for hypertension management. It was an 8-week prospective, randomized, open, blinded end points design study. General practitioners (GPs) located in France were randomized in two groups: group 1 (G1) without training to the guidelines and free attitude for the prescription whereas group 2 (G2) received a specific training in ESH guidelines. The primary efficacy criteria was strict BP control at week 8 (systolic BP/diastolic BP [SBP/DBP] <140/90 mm Hg and/or SBP/DBP <130/80 mm Hg if diabetes or renal insufficiency). All physicians used the same treatment (valsartan 80 or 160 mg once daily alone or in fixed combination with hydrochlorothiazide 12.5 or 25 mg once daily). BP was measured in the GPs' office with an electronic device. The groups GPs included 4,436 patients with essential uncontrolled hypertension (G1: 595 physicians, 2,308 patients; G2: 502 physicians, 2,128 patients). Patients' main characteristics were: age = 61 +/- 13 years, 52% female, BP = 160 +/- 13/92 +/- 9 mm Hg. No difference was observed between the two groups. The primary efficacy criteria showed in G2: 47.8% of BP control vs. G1: 44.7%, P = .005. Subgroup analysis according to age, body mass index (BMI), previous diabetes, and antihypertensive treatment showed that higher efficacy in G2 was more significant in these high-risk subgroups: age >60 years (G1: n = 1,150, G2: n = 1,035), BMI >/=25 kg/m(2) (G1: n = 1540, G2: n = 1430), diabetes (G1: n = 267, G2: n = 290), no previous antihypertensive treatment (G1: n = 1,111, G2: n = 1,005). The percentage of patients with controlled BP in each subgroup was: diabetes: G1 11.2% vs. G2 17.9% (P = .001), age >60 years: G1 40.3% vs. G2 43.7% (P = .022), BMI >/=25 kg/m(2): G1 43.2% vs. G2 45% (P = .165), untreated: G1 48.2% vs. G2 52.4% (P = .005). Specific training on the guidelines showed a positive impact on BP control, highly significant in patients at high cardiovascular risk such as diabetic hypertensive patients.

Home blood pressure during normal pregnancy.

To determine values for home blood pressure (HBP) during pregnancy, nurses taught 45 healthy pregnant women to use a HBP method for 1 week before 15 weeks of gestation, between weeks 15 and 27, and after 28 weeks for the last 3 months of gestation. HBP values were significantly lower during the second trimester and higher during the last trimester (102 +/- 8/59 +/- 7*, 101 +/- 8/57 +/- 8*, 105 +/- 8*/62 +/- 9* mm Hg;*P< 0.05) than during other trimesters. Heart rate increased significantly during the pregnancy. The present study suggests upper limits for HBP: 118/73, 117/73, and 121/80 mm Hg, respectively during the 3-month gestational periods. These findings may be helpful in providing clinicians with comparative values so as begin to establish reference values for HBP during pregnancy.
