This paper examines baseline characteristics from a prospective, cluster‐randomized trial in 32 primary care offices. Offices were first stratified by percentage of minorities and level of clinical pharmacy services and then randomized into 1 of 3 study groups. The only differences between randomized arms were for marital status (P=.03) and type of insurance coverage (P<.001). Blood pressures (BPs) were similar in Caucasians and minority patients, primarily blacks, who were hypertensive at baseline. On multivariate analyses, patients who were 65 years and older had higher systolic BP (152.4±14.3 mm Hg), but lower diastolic BP (77.3±11.8 mm Hg) compared with those younger than 65 years (147.4±15.0/88.6±10.6 mm Hg, P<.001 for both systolic and diastolic BP). Other factors significantly associated with higher systolic BP were a longer duration of hypertension (P=.04) and lower basal metabolic index (P=.011). Patients with diabetes or chronic kidney disease had a lower systolic BP than those without these conditions (P<.0001). BP was similar across racial and socioeconomic groups for patients with uncontrolled hypertension in primary care, suggesting that patients with uncontrolled hypertension and an established primary care relationship likely have different reasons for poor BP control than other patient populations.  相似文献

A direct relationship between serum uric acid and blood pressure (BP) has been reported, but the possible confounding impact of diet on this association is unclear. The authors performed a cross‐sectional analysis in the representative German Health Interview and Examination Survey for Adults (n=6788, aged 18–79 years). In adjusted regression models considering dietary factors, each 1‐mg/dL higher uric acid value was associated with a 1.10‐mm Hg (P=.0002) and a 0.60‐mm Hg (P=.04) higher systolic BP among participants younger than 50 years and participants 50 years and older, respectively. For diastolic BP, uric acid was a significant predictor (β=0.71 mm Hg, P=.0001) among participants younger than 50 years and for participants 50 years and older without antihypertensive treatment. Adjusted odds ratios of hypertension for participants with hyperuricemia were broadly similar in younger (odds ratio, 1.71; P=.02) and older (odds ratio, 1.81; P=.0003) participants. Uric acid is a significant predictor of systolic BP and hypertension prevalence in the general adult population in Germany independently of several known dietary BP influences.  相似文献

The authors investigated whether erectile dysfunction (ED) in the early stages of hypertension is associated with heightened end‐organ damage. A total of 174 consecutive men with untreated, newly diagnosed essential hypertension (aged 50.3 years, office blood pressure [BP] 150/98 mm Hg) were studied. All participants underwent 24‐hour ambulatory BP monitoring, blood examination, albumin‐creatinine ratio, carotid‐femoral pulse‐wave velocity assessment, and echocardiography for estimation of left ventricular mass index and diastolic function. Hypertensive men with ED (n=43, 24.7%) compared with those without ED were older (by 6.4 years, P<.05), had greater 24‐hour pulse pressure (by 4.3 mm Hg, P=.011) and a greater prevalence of nondipping status (72.2% vs 46.7%, P=.008), while the two groups did not differ in plasma glucose, lipid, creatinine, and albumin/creatinine ratio levels. Regarding cardiac adaptations, hypertensive men with ED exhibited only significantly lower tissue Doppler imaging–derived Em (by 1.6 cm/s, adjusted P=.035), while no difference in left ventricular mass index or pulse wave velocity were detected. ED in the setting of untreated newly diagnosed essential hypertension does not have an unfavorable impact on traditional markers of target organ damage. This finding suggests that ED assessment might not refine the traditional risk stratification procedure at least in the early stages of hypertensive disease.  相似文献

The correlation between creatine kinase (CK) and blood pressure (BP) was examined prospectively in 120 patients with persistent high CK and 130 individuals with normal CK. Hypertension was defined as systolic BP (SBP) ≥140 mm Hg or diastolic BP (DBP) ≥90 mm Hg or current use of antihypertensive medication. Baseline CK was weakly correlated with SBP (r=0.11, P=.07) and DBP (r=0.16, P=.01) at follow‐up. Persons with persistent high CK had higher SBP (140.8 mm Hg vs 138.2 mm Hg) and DBP (83.2 mm Hg vs 81.0 mm Hg, P=.06) values and were more likely to have hypertension (66.7% vs 55.5%, P=.05) than individuals with normal CK. In age‐ and sex‐adjusted analysis, a 1‐unit change in logCK was associated with a 4.9‐mm Hg higher SBP, a 3.3‐mm Hg higher DBP, and a 2.2‐higher odds for having hypertension at follow‐up (P=.1, .07, and .06, respectively). When including body mass index (BMI) to the model, BMI was a strong and independent predictor for SBP, DBP, and hypertension at follow‐up and the CK effect on blood pressure was substantially attenuated. This study showed that the CK effect on blood pressure is clearly modified by BMI.  相似文献

The authors aimed to investigate the blood pressure (BP)–lowering ability of eplerenone in drug‐resistant hypertensive patients. A total of 57 drug‐resistant hypertensive patients whose home BP was ≥135/85 mm Hg were investigated. The patients were randomized to either an eplerenone group or a control group and followed for 12 weeks. The efficacy was evaluated by clinic, home, and ambulatory BP monitoring. Urinary albumin, pulse wave velocity, and flow‐mediated vasodilation (FMD) were also evaluated. Home morning systolic BP (148±15 vs 140±15 mm Hg) and evening systolic BP (137±16 vs 130±16 mm Hg) were significantly lowered in the eplerenone group (n=35) compared with baseline (both P<.05), while unchanged in the control group (n=22). BP reductions in the eplerenone group were most pronounced for ambulatory awake systolic BP (P=.04), awake diastolic BP (P=.004), and 24‐hour diastolic BP (P=.02). FMD was significantly improved in the eplerenone group. In patients with drug‐resistant hypertension, add‐on use of eplerenone was effective in lowering BP, especially home and ambulatory awake BP.  相似文献

The impact of age‐related differences in blood pressure (BP) components on new‐onset hypertension is not known. A follow‐up examination of 93 303 normotensive individuals (mean age 41.1 years) who underwent a health checkup in 2005 was conducted every year for 8 years. The primary end point was new‐onset hypertension (systolic BP [SBP]/diastolic BP [DBP] ≥140/90 mm Hg and/or the initiation of antihypertensive medications with self‐reported hypertension). During the mean 4.9 years of follow‐up, 14 590 subjects developed hypertension. The impact of DBP on the risk of developing hypertension compared with optimal BP (SBP <120 mm Hg and DBP <80 mm Hg) was significantly greater than that of SBP in subjects younger than 50 years (hazard ratios, 17.5 for isolated diastolic high‐normal vs 10.5 for isolated systolic high‐normal [P<.001]; 8.0 for isolated diastolic normal vs 4.1 for isolated systolic normal [P<.001]). Among the subjects 50 years and older, the corresponding effects of DBP and SBP were similar. Regarding the risk of new‐onset hypertension, high DBP is more important than SBP in younger adults (<50 years) with normal or high‐normal BP.  相似文献

To examine the antihypertensive efficacy and safety of indapamide sustained‐release (SR)/amlodipine compared with enalapril/amlodipine in patients 65 years and older with uncontrolled blood pressure (BP) on monotherapy, a post hoc analysis of the NESTOR trial (Natrilix SR vs Enalapril in Hypertensive Type 2 Diabetics With Microalbuminuria) was conducted. NESTOR randomized 570 patients (n=197, aged ≥65 years) with hypertension (systolic BP 140–180/diastolic BP <110 mm Hg) to indapamide SR 1.5 mg or enalapril 10 mg. If target BP (<140/85 mm Hg) was not achieved at 6 weeks, amlodipine 5 mg was added with uptitration to 10 mg if required. A total of 107 patients aged 65 years and older received dual therapy (53 indapamide SR/amlodipine and 54 enalapril/amlodipine). Amlodipine uptitration occurred in 22 and 24 patients, respectively. At 52 weeks, mean systolic BP (±SE) reduction was significantly greater with indapamide SR/amlodipine vs enalapril/amlodipine 6.2±2.7 mm Hg (P=.02). Indapamide SR/amlodipine was also associated with a greater BP response rate (88% vs 75%, respectively). Both regimens were well tolerated. Indapamide SR/amlodipine may be more effective than enalapril/amlodipine for lowering systolic BP in patients with hypertension aged 65 years and older.  相似文献

High aldosterone levels are considered to play a key role in arterial hypertension. Data on the relationship between the aldosterone to active renin ratio (AARR), a quantity of aldosterone excess, and ambulatory blood pressure (BP) monitoring (ABPM) during the night are, however, sparse. Hypertensive patients were recruited from local outpatient clinics who underwent 24‐hour urine collection and in parallel ABPM. Plasma aldosterone and renin concentrations were measured by radioimmunoassay. A total of 211 patients (age, 60.2±10.2 years; 51.9% female) with a mean systolic/diastolic ABPM value of 128.7±12.8/77.1±9.2 mm Hg were evaluated. In backwards linear regression analyses adjusted for age, sex, body mass index, smoking, glomerular filtration rate, hemoglobin A1c, N‐terminal prohormone of brain natriuretic peptide, urinary sodium/potassium ratio, and ongoing antihypertensive medication, AARR was significantly associated with nocturnal systolic (ß‐coefficient: 0.177; P=.017) and diastolic BP (ß‐coefficient: 0.162; P=.027). In patients with arterial hypertension, a significant association between AARR and nighttime BP even after adjustment for a broad panel of confounders was found.  相似文献

The authors sought to retrospectively analyze the real‐world evidence on aliskiren in diabetic patients with or without concomitant renin‐angiotensin system (RAS) blocker use based on the Registry for Ambulant Therapy With RAS Inhibitors in Hypertension Patients in Germany (3A). Of 14,986 patients included, 3772 patients had diabetes and 28.5% received aliskiren, 14.3% received angiotensin‐converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs), 35.4% received aliskiren plus an ACE inhibitor/ARB, and 10.5% received other drugs. Ambulatory blood pressure (BP) monitoring (baseline BP 148±15.8/84.0±10.9 mm Hg) revealed stronger diastolic BP reduction for aliskiren plus ACE inhibitor/ARB than aliskiren alone in the low (2.8±0.5 vs 0.6±0.6; P=.004) and intermediate (5.9±0.5 vs 4.5±0.5; P=.04) baseline BP groups. There was a lesser ambulatory BP reduction observed for patients receiving non‐RAS in the high baseline category for both systolic (12.5±1.8 vs 17.1±1.0; P=.02) and diastolic (6.9±1.0 vs 9.8±0.6; P=.01) BP. In patients with hypertension and type 2 diabetes, aliskiren was beneficial in lowering BP, with no observed increases in major adverse effects compared with RAS‐blocking therapy alone.  相似文献

Blood pressure (BP) behavior during exercise is not clear in hypertensive patients with obstructive sleep apnea (OSA). The authors studied 57 men with newly diagnosed essential hypertension and untreated OSA (apnea‐hypopnea index [AHI] ≥5) but without daytime sleepiness (Epworth Sleepiness Scale score ≤10), and an equal number of hypertensive controls without OSA matched for age, body mass index, and office systolic BP. All patients underwent ambulatory BP measurements, transthoracic echocardiography, and exercise treadmill testing according to the Bruce protocol. A hypertensive response to exercise (HRE) was defined as peak systolic BP ≥210 mm Hg. Patients with OSA and control patients had similar ambulatory and resting BP, ejection fraction, and left ventricular mass. Peak systolic BP was significantly higher in patients with OSA (197.6±25.6 mm Hg vs 187.8±23.6 mm Hg; P=.03), while peak diastolic BP and heart rate did not differ between groups. Furthermore, an HRE was more prevalent in patients with OSA (44% vs 19%; P=.009). Multiple logistic regression revealed that an HRE is independently predicted by both the logAHI and minimum oxygen saturation during sleep (odds ratio, 3.94; confidence interval, 1.69–9.18; P=.001 and odds ratio, 0.94; confidence interval, 0.89–0.99; P=.02, respectively). Exaggerated BP response is more prevalent in nonsleepy hypertensives with OSA compared with their nonapneic counterparts. This finding may have distinct diagnostic and prognostic implications.  相似文献

The authors investigated whether a genetic risk score (GRS) constructed of 32 single nucleotide polymorphisms would predict incident hypertension and blood pressure (BP) change over time in a population cohort during an 11‐year follow‐up (n=5402 at baseline, 3266 at follow‐up). In multivariable models, GRS was associated with higher systolic/diastolic BP values at baseline (β±standard error [SE], 1.04±0.14/1.11±0.13 mm Hg; P<.0001 for both) and at reinvestigation (β±SE, 0.84±0.18/0.79±0.16 mm Hg; P<.0001 for both). Among participants who were normotensive at baseline (n=2045), GRS was not independently associated with systolic/diastolic BP change over time (β±SE, 0.16±0.18/0.20±0.18 mm Hg; P≥.28 for both). In participants in the top tertile of the GRS, as compared with the bottom tertile, the predicted increase in systolic/diastolic BP was 1.18±0.78/0.70±0.49 mm Hg (P=.046/.15) greater and the odds ratio for incident hypertension was 33% higher (P=.03). These data show that GRS is strongly associated with BP but weakly associated with BP increase and incident hypertension in a late middle‐aged population.  相似文献

Whether sex influences the association of obstructive sleep apnea (OSA) with markers of cardiovascular risk in patients with hypertension is unknown. In this study, 95 hypertensive participants underwent carotid‐femoral pulse wave velocity, 24‐hour ambulatory blood pressure monitoring, echocardiogram, and polysomnography after a 30‐day standardized treatment with hydrochlorothiazide plus enalapril or losartan. OSA was present in 52 patients. Compared with non‐OSA patients, pulse wave velocity values were higher in the OSA group (men: 11.1±2.2 vs 12.7±2.4 m/s, P=.04; women: 11.8±2.4 vs 13.2±2.2 m/s, P=.03). The proportion of diastolic dysfunction was significant in men and women with OSA. Compared with non‐OSA patients, nondipping systolic blood pressure in OSA was higher in men (14.3% vs 46.4%) and in women (41.4% vs 65.2%). OSA was independently associated with pulse wave velocity (β=1.050; P=.025) and nondipping systolic blood pressure (odds ratio, 3.03; 95% confidence interval, 1.08–8.55; P=.035) in the regression analysis. In conclusion, OSA is independently associated with arterial stiffness and nondipping blood pressure in patients with hypertension regardless of sex.  相似文献

This blinded placebo‐controlled crossover study evaluated the acute effects of an orally disintegrating lozenge that generates nitric oxide (NO) in the oral cavity on blood pressure (BP) response, endothelial function, and vascular compliance in unmedicated hypertensive patients. Thirty patients with clinical hypertension were recruited and enrolled in a blinded placebo‐controlled clinical trial in an outpatient setting. Average baseline BP in 30 patients was 144±3/91±1 mm Hg. NO supplementation resulted in a significant decrease of 4 mm Hg in resting systolic BP (P<.003) and a significant decrease of 5 mm Hg in diastolic BP (P<.002) from baseline and placebo after 20 minutes. In addition, there was a further statistically significant reduction by 6 mm Hg in both systolic and diastolic pressure after 60 minutes (P<.0001 vs baseline). After a half hour of a single dose, there was a significant improvement in vascular compliance as measured by augmentation index and, after 4 hours, a statistically significant improvement in endothelial function as measured by the EndoPAT (Itamar Medical, Franklin, MA). A single administration of an oral active NO supplement appears to acutely lower BP, improve vascular compliance, and restore endothelial function in patients with hypertension.  相似文献

This retrospective cohort study compared administration of lisinopril twice daily and once daily for hypertension. Data were collected from an ambulatory electronic health record between 2011 and 2014. Patients previously receiving lisinopril 20 mg were placed into the once‐daily cohort if changed to 40 mg once daily or into the twice‐daily cohort if changed to 20 mg twice daily. Efficacy outcome measures were change in systolic blood pressure and diastolic blood pressure and achievement of blood pressure control (<140/90 mm Hg). Of 90 patients included (45 per cohort), the mean age was 61.8 years and 17.8% were black. Once‐ and twice‐daily administrations were associated with blood pressure reductions of 6.2/1.5 mm Hg and 16.5/5.9 mm Hg, with a 10.2/4.3 mm Hg greater reduction with twice‐daily administration (systolic blood pressure, P=.016; diastolic blood pressure, P=.068). Twice‐daily lisinopril dosing was associated with greater systolic blood pressure reductions compared with the same total daily dose administered once daily.  相似文献

The purpose of this study was to determine whether responders (minimum 4‐mm Hg reduction of systolic blood pressure [BP]) at 24 weeks) to a 52‐week lifestyle intervention had greater changes in metabolic risk factors and health‐related quality of life than nonresponders. Participants (N=126; age, 57.4 [9.1] years) had waist circumference (WC), resting BP, glycated hemoglobin, lipids, and fitness assessed at baseline and at 12, 24, and 52 months. The 36‐item short‐form survey was administered to assess HRQOL. At baseline, responders had higher mental health scores (P=.04) and systolic and diastolic BPs (P<.001) than nonresponders. Across 52 weeks, responders also had greater improvements in diastolic BP (P<.001), WC (P=.01), and maximal oxygen uptake (P=.04) compared with nonresponders. Participants with clinically important changes in systolic BP at 24 weeks had greater metabolic improvements across 52 weeks, compared with those without clinically important systolic BP changes.  相似文献

A direct switch of candesartan to the fixed‐dose combination olmesartan/amlodipine in uncontrolled hypertension is a frequent clinical requirement but is not covered by current labeling. An open‐label, prospective, single‐arm phase IIIb study was performed in patients with 32 mg candesartan followed by olmesartan/amlodipine 40/10 mg. The primary endpoint was change in mean daytime systolic blood pressure (BP). Mean daytime systolic BP was reduced by 9.2±12.6 mm Hg (P<.0001) after substituting candesartan for olmesartan/amlodipine (baseline BP 140.2±9.7 mm Hg). The reduction in office BP was 9.4±18.4/4.0±9.6 mm Hg; P<.002). Overall, 61.3% of patients achieved a target BP <140/90 mm Hg using office BP and <135/85 mm Hg using ambulatory BP measurement. There were 8 adverse events with a possible relation to study drug and 1 unrelated serious adverse events. In conclusion, patients with uncontrolled moderate arterial hypertension being treated using candesartan monotherapy achieve a further reduction of BP when switched directly to a fixed‐dose combination of olmesartan 40 mg/amlodipine 10 mg.  相似文献

Patients with primary hyperparathyroidism are at increased risk for high blood pressure, vascular stiffening, and left ventricular hypertrophy, but previous studies have failed to demonstrate the direct associations with circulating parathyroid hormone (PTH) levels. The authors investigated cross‐sectional relationships between PTH and 24‐hour pulse wave velocity, nocturnal systolic blood pressure, and left ventricular mass index in patients with primary hyperparathyroidism who were treatment‐naive with cinacalcet, renin‐angiotensin‐aldosterone‐system inhibitors, and thiazide or loop diuretics. In 76 patients, mean±SD of pulse wave velocity, nocturnal systolic blood pressure, and left ventricular mass index values were 9.3±1.8 m/s, 116.6±17.0 mm Hg, and 92.8±23.0 g/m². In multivariate linear regression analyses with adjustment for potentially confounding parameters, PTH was independently associated with nocturnal systolic blood pressure (adjusted ß coefficient=.284, P=.040), mean 24‐hour pulse wave velocity (ß=.199, P=.001), and left ventricular mass index (ß=.252, P=.025). PTH may promote vascular and cardiac remodeling in primary hyperparathyroidism. Interventional trials are needed to test the antihypertensive and cardioprotective effects of PTH‐inhibitory treatment strategies.  相似文献

In a multicenter, randomized trial, we investigated whether the long half‐time dihydropyridine calcium channel blocker amlodipine was more efficacious than the gastrointestinal therapeutic system (GITS) formulation of nifedipine in lowering ambulatory blood pressure (BP) in sustained hypertension (clinic systolic/diastolic BP 140‐179/90‐109 mm Hg and 24‐hour systolic/diastolic BP ≥ 130/80 mm Hg). Eligible patients were randomly assigned to amlodipine 5‐10 mg/day or nifedipine‐GITS 30‐60 mg/day. Ambulatory BP monitoring was performed for 24 hours at baseline and 4‐week treatment and for 48 hours at 8‐week treatment with a dose of medication missed on the second day. After 8‐week treatment, BP was similarly reduced in the amlodipine (n = 257) and nifedipine‐GITS groups (n = 248) for both clinic and ambulatory (24‐hour systolic/diastolic BP 10.3/6.5 vs 10.9/6.3 mm Hg, P ≥ 0.24) measurements. However, after missing a dose of medication, ambulatory BP reductions were greater in the amlodipine than nifedipine‐GITS group, with a significant (P ≤ 0.04) between‐group difference in 24‐hour (–1.2 mm Hg) and daytime diastolic BP (–1.5 mm Hg). In conclusion, amlodipine and nifedipine‐GITS were efficacious in reducing 24‐hour BP. When a dose of medication was missed, amlodipine became more efficacious than nifedipine‐GITS.  相似文献

Automated office blood pressure measurement eliminates the white coat effect and is associated with awake ambulatory blood pressure. This study examined whether automated office blood pressure values at lower limits were comparable to those of awake and mean 24‐hour ambulatory blood pressure. A total of 552 patients were included in the study, involving 293 (53.1%) men and 259 (46.9%) women, with a mean age 55.0 ± 12.5, of whom 36% were treated for hypertension. Both systolic and diastolic automated office blood pressures exhibited lower values compared to awake ambulatory blood pressure among 254 individuals with systolic automated office blood pressure <130 mm Hg (119 ± 8 mm Hg vs 125 ± 11 mm Hg, P < .0001 and 75 ± 9 mm Hg vs 79 ± 9 mm Hg, P < .0001 for systolic and diastolic BPs, respectively). Furthermore, the comparison of systolic automated office blood pressure to the mean 24‐hour ambulatory blood pressure levels also showed lower values (119 ± 8 vs 121 ± 10, P = .007), whereas the diastolic automated office blood pressure measurements were similar to 24‐hour ambulatory blood pressure values. Our findings show that when automated office blood pressure readings express values <130/80 mm Hg in repeated office visits, further investigation should be performed only when masked hypertension is suspected; otherwise, higher automated office blood pressure values could be used for the diagnosis of uncontrolled hypertension, especially in individuals with organ damage.  相似文献

In this secondary analysis of the Weight Loss Maintenance trial, the authors assessed the relationship between blood pressure (BP) change and weight change in overweight and obese adults with hypertension and/or dyslipidemia who were randomized to 1 of 3 weight loss maintenance strategies for 5 years. The participants were grouped (N=741) based on weight change from randomization to 60 months as: (1) weight loss, (2) weight stable, or (3) weight gain. A significant positive correlation between weight change and systolic BP (SBP) change at 12, 30, and 60 months and between weight change and diastolic BP (DBP) change at 30 months was observed. From randomization to 60 months, mean SBP increased to a similar degree for the weight gain group (4.2±standard error=0.6 mm Hg; P<.001) and weight stable group (4.6±1.1 mm Hg; P<.001), but SBP did not rise in the weight loss group (1.0±1.7 mm Hg, P=.53). DBP was unchanged for all groups at 60 months. Although aging may have contributed to rise in BP at 60 months, it does not appear to fully account for observed BP changes. These results suggest that continued modest weight loss may be sufficient for long‐term BP lowering.  相似文献
