Project description:Recent publications have stated that the blood pressure (BP) measurement technique used in SPRINT (Systolic Blood Pressure Intervention Trial) was unattended. However, the SPRINT protocol does not address the issue of attendance. A survey was conducted immediately after SPRINT closeout visits were completed to inquire whether BP measurements were usually attended or unattended by staff. There were 4082 participants at 38 sites that measured BP after leaving the participant alone the entire time (always alone), 2247 at 25 sites that had personnel in the room the entire time (never alone), 1746 at 19 sites that left the participant alone only during the rest period (alone for rest), and 570 at 6 sites that left the participant alone only during the BP readings (alone for BP measurement). Similar systolic and diastolic BPs within randomized groups were noted during follow-up at the majority of visits in all 4 measurement categories. In the always alone and never alone categories, the intensive group had a similarly reduced risk for the primary outcome compared with the standard group (hazard ratio, 0.62; 95% confidence interval, 0.51-0.76 and hazard ratio, 0.64; 95% confidence interval, 0.46-0.91, respectively; pairwise interaction P value, 0.88); risk was not significantly reduced for the intensive group in the smaller alone-for-rest and the alone-for-BP-measurement categories. Similar BP levels and cardiovascular disease risk reduction were observed in the intensive group in SPRINT participants whether the measurement technique used was primarily attended or unattended.Clinical trial registrationURL: http://www.clinicaltrials.gov.

Project description:ObjectiveEngaging in physical activity (PA) is recommended to reduce the risk of morbidity and mortality in patients with hypertension. However, the association between PA and clinical outcomes in individuals with high-risk hypertension is understudied. We examined the relationship between PA and clinical outcomes in the Systolic Blood Pressure Intervention Trial (SPRINT). SPRINT investigated the benefit of intensive (vs. standard) blood pressure treatment in patients with high-risk hypertension.MethodsBaseline data on PA was self-reported. Vigorous-intensity PA (VPA) was categorized into 2 groups based on frequency of "Rarely or Never" and 1 or more sessions/month. Moderate-intensity PA (MPA) was also categorized into 2 groups based on average duration/day of <15 min and 15 or more minutes. Using multivariable Cox regression, we estimated the associations between PA the primary outcome which was a composite of cardiovascular events, and all-cause mortality.ResultsA total of 8,320 (age 67.8 ± 9.3, 34.9% women) of SPRINT participants with data on PA were included. During a median follow-up of 3.8 years, 619 primary outcome, and 419 all-cause mortality events occurred. Compared to not engaging in VPA, the risk of the primary outcome, myocardial infarction, and all-cause mortality (HR 95% CIs) associated with VPA of ≥1sessions/month was 0.79(0.65-0.94; p=0.009), 0.70(0.52-0.93; p=0.014) and 0.75(0.60-0.94; p=0.011), respectively. Similarly, the risk of the primary outcome and all-cause mortality (HR 95% CI) associated with engaging in MPA for ≥15 min/day, relative to <15 min/day was 0.76(0.63-0.93; p=0.008) and 0.80(0.62-1.02; p=0.066), respectively.ConclusionAmong individuals with hypertension from the SPRINT study, VPA and MPA at a threshold of ≥1sessions/month and MPA of ≥15 min/day respectively, were both associated with a lower risk for cardiovascular events, and VPA was also associated with a reduced risk for all-cause mortality. Further studies are required to identify the optimal volume and intensity of PA in high-risk hypertension.

Project description:INTRODUCTION:Sexual function, an important component of quality of life, is gaining increased research and clinical attention in older women with hypertension. AIM:To assess the association between systolic blood pressure (SBP) and other variables, and sexual activity and sexual dysfunction in hypertensive women. METHODS:Baseline analysis of 635 women participants of a larger randomized clinical trial of 9361 men and women. MAIN OUTCOME MEASURES:Self-reported sexual activity (yes/no), and sexual function using the Female Sexual Function Inventory (FSFI). RESULTS:452 participants (71.2%) reported having no sexual activity during the previous 4 weeks. The mean (SD) FSFI score for sexually active participants was 25.3 (6.0), and 52.6% of the sample reported a FSFI score ?26.55 designating sexual dysfunction. In logistic regression models, SBP was not significantly associated with sexual activity (AOR = 1.002; P > .05). Older age (AOR = 0.95, P < .05), and lower education (AOR for < high school vs college degree = 0.29, P < .05) were associated with lower odds of being sexually active, as was living alone versus living with others (AOR = 0.56, P < .05). Higher weekly alcohol consumption was associated with increased odds of being sexually active (AOR = 1.39; P < .05). In logistic regression models among sexually active participants, SBP was not associated with sexual dysfunction (AOR = 1.01; P > .05). Higher depressive symptoms from the Patient Health Questionnaire-9 (PHQ-9) was associated with higher odds of sexual dysfunction (AOR = 1.24, P < .05), as was increased number of physical comorbidities (AOR = 1.25, P < .05). Diuretic use was associated with lower odds of being sexually active in participants with chronic kidney disease (AOR = 0.33, P < .05). CONCLUSION:Younger age, higher education, living with others, and higher weekly alcohol consumption were significantly associated with higher odds of being sexually active in a sample of middle-aged and older women with hypertension. Increased depressive symptoms and increased physical comorbidities were significantly associated with increased odds of sexual dysfunction. SBP was not significantly associated with sexual activity or sexual dysfunction.

Project description:BACKGROUND:It is currently unknown whether intensive blood pressure (BP) lowering beyond that recommended would lead to more lowering of the risk of left ventricular hypertrophy (LVH) in patients with hypertension and whether reducing the risk of LVH explains the reported cardiovascular disease (CVD) benefits of intensive BP lowering in this population. METHODS:This analysis included 8164 participants (mean age, 67.9 years; 35.3% women; 31.2% blacks) with hypertension but no diabetes mellitus from the SPRINT trial (Systolic Blood Pressure Intervention Trial): 4086 randomly assigned to intensive BP lowering (target SBP <120 mm Hg) and 4078 assigned to standard BP lowering (target SBP <140 mm Hg). Progression and regression of LVH as defined by Cornell voltage criteria derived from standard 12-lead ECGs recorded at baseline and biannually were compared between treatment arms during a median follow-up of 3.81 years. The effect of intensive (versus standard) BP lowering on the SPRINT primary CVD outcome (a composite of myocardial infarction, acute coronary syndrome, stroke, heart failure, and CVD death) was compared before and after adjustment for LVH as a time-varying covariate. RESULTS:Among SPRINT participants without baseline LVH (n=7559), intensive (versus standard) BP lowering was associated with a 46% lower risk of developing LVH (hazard ratio=0.54; 95% confidence interval, 0.43-0.68). Similarly, among SPRINT participants with baseline LVH (n=605, 7.4%), those assigned to the intensive (versus standard) BP lowering were 66% more likely to regress/improve their LVH (hazard ratio=1.66; 95% confidence interval, 1.31-2.11). Adjustment for LVH as a time-varying covariate did not substantially attenuate the effect of intensive BP therapy on CVD events (hazard ratio of intensive versus standard BP lowering on CVD, 0.76 [95% confidence interval, 0.64-0.90] and 0.77 [95% confidence interval, 0.65-0.91] before and after adjustment for LVH as a time-varying covariate, respectively). CONCLUSIONS:Among patients with hypertension but no diabetes mellitus, intensive BP lowering (target systolic BP <120 mm Hg) compared with standard BP lowering (target systolic BP <140 mm Hg) resulted in lower rates of developing new LVH in those without LVH and higher rates of regression of LVH in those with existing LVH. This favorable effect on LVH did not explain most of the reduction in CVD events associated with intensive BP lowering in the SPRINT trial.

Project description:BackgroundUncontrolled blood pressure (BP) increases the risk of major adverse cardiovascular events. In SPRINT an intensive versus standard BP lowering strategy resulted in a lower rate of cardiovascular events and death. Whether BP reduction only or also the choice of anti-hypertensive drugs is associated with outcomes remains to be elucidated.AimsWe aim to study the association of BP and different anti-hypertensive drugs with several cardiovascular outcomes.MethodsTime-updated Cox and mixed-effects models. The primary outcome was a composite of first myocardial infarction, acute coronary syndrome, stroke, heart failure, or cardiovascular death.ResultsA total of 9361 patients were included. The anti-hypertensive agents most frequently used were ACEi/ARBs, with an almost 20% higher prescription rate in the intensive arm (80% vs. 61%), followed by thiazide-type diuretics (65% vs. 42%), calcium-channel blockers (57% vs. 39%), and beta-blockers (52% vs. 26%). Mineralocorticoid receptor antagonists were rarely used (≤7% of the observations). In multivariate analysis, the use of ACEi/ARBs, especially in combination with thiazides, were independently associated with a lower primary outcome event-rate (HR [95%CI] 0.75 [0.61-0.92], p = .006), whereas a DBP <60 mmHg was independently associated with a higher event-rate (HR [95%CI] 1.36 [1.07-1.71], p = .011). SBP <120 mmHg was associated with lower rate of cardiovascular and all-cause death on intensive treatment but not on the standard arm (interaction p < .05 for both).ConclusionsIn SPRINT, an intensive therapy strategy achieving SBP <120 mmHg with a DBP ≥60 mmHg, and using ACEi/ARBs plus thiazides was associated with a lower event-rate.

Project description:Background: Poor cognitive function can predict poor clinical outcomes. Intensive blood pressure control can reduce the risk of cardiovascular diseases and all-cause mortality. In this study, we assessed whether intensive blood pressure control in older patients can reduce the risk of stroke, composite cardiovascular outcomes and all-cause mortality for participants in the Systolic Blood Pressure Intervention Trial (SPRINT) with lower or higher cognitive function based on the Montreal Cognitive Assessment (MoCA) cut-off scores. Methods: The SPRINT evaluated the impact of intensive blood pressure control (systolic blood pressure <120 mmHg) compared with standard blood pressure control (systolic blood pressure <140 mmHg). We defined MoCA score below education specific 25th percentile as lower cognitive function. And SPRINT participants with a MoCA score below 21 (<12 years of education) or 22 (≥12 years of education) were having lower cognitive function, and all others were having higher cognitive function. The Cox proportional risk regression was used to investigate the association of treatment arms with clinical outcomes and serious adverse effects in different cognitive status. Additional interaction and stratified analyses were performed to evaluate the robustness of the association between treatment arm and stroke in patients with lower cognitive function. Results: Of the participants, 1,873 were having lower cognitive function at baseline. The median follow-up period was 3.26 years. After fully adjusting for age, sex, ethnicity, body mass index, smoking, systolic blood pressure, Framingham 10-year CVD risk score, aspirin use, statin use, previous cardiovascular disease, previous chronic kidney disease and frailty status, intensive blood pressure control increased the risk of stroke [hazard ratio (HR) = 1.93, 95% confidence interval (CI): 1.04-3.60, P = 0.038)] in patients with lower cognitive function. Intensive blood pressure control could not reduce the risk of composite cardiovascular outcomes (HR = 0.81, 95%CI: 0.59-1.12, P = 0.201) and all-cause mortality (HR = 0.93, 95%CI: 0.64-1.35, P = 0.710) in lower cognitive function group. In patients with higher cognitive function, intensive blood pressure control led to significant reduction in the risk of stroke (HR = 0.55, 95%CI: 0.35-0.85, P = 0.008), composite cardiovascular outcomes (HR = 0.68, 95%CI: 0.56-0.83, P < 0.001) and all-cause mortality (HR = 0.62, 95%CI: 0.48-0.80, P < 0.001) in the fully adjusted model. Additionally, after the full adjustment, intensive blood pressure control increased the risk of hypotension and syncope in patients with lower cognitive function. Rates of hypotension, electrolyte abnormality and acute kidney injury were increased in the higher cognitive function patients undergoing intensive blood pressure control. Conclusion: Intensive blood pressure control might not reduce the risk of stroke, composite cardiovascular outcomes and all-cause mortality in patients with lower cognitive function.

Project description:Recent studies including the SPRINT trial have shown beneficial effects of intensive systolic blood pressure reduction over the standard approach. The awareness of the J-curve for diastolic blood pressure (DBP) causes some uncertainty regarding the net clinical effects of blood pressure reduction. The current analysis was performed to investigate effects of low on-treatment DBP on cardiovascular risk in the SPRINT population. The primary composite outcome was the occurrence of myocardial infarction, acute coronary syndrome not resulting in myocardial infarction, stroke, acute decompensated heart failure or death from cardiovascular causes. The prevalence of primary outcomes was significantly higher in subjects within low DBP in both standard (44-67 mmHg [10.8%] vs 67-73 mmHg [6.7%] vs 73-78 mmHg [5.1%] vs 78-83 mmHg [4.4%] vs 83-113 mmHg [4.3%], p < 0.001) and intensive treatment (38-61 mmHg [6.7%] vs 61-66 mmHg [4.1%] vs 66-70 mmHg [4.5%] vs 70-74 mmHg [2.7%] vs 74-113 mmHg [3.4%], p < 0.001) arms. After adjusting for covariates, low DBP showed no significant effects on cardiovascular risk. Therefore, while reaching blood pressure targets, low DBP should not be a matter of concern.

Project description:Orthostatic changes in systolic blood pressure (SBP) impact cardiovascular outcomes. In this study, we aimed to determine the pattern of orthostatic systolic pressure changes in participants enrolled in the SBP Intervention Trial (SPRINT) at their baseline visit before randomization and sought to understand clinical factors predictive of these changes. Of the 9323 participants enrolled in SPRINT, 8662 had complete data for these analyses. The SBP after 1 minute of standing was subtracted from the mean value of the three preceding seated SBP values. At the baseline visit, medical history, medications, anthropometric measures, and standard laboratory testing were undertaken. The mean age of SPRINT participants was 68 years, two-thirds were male, with 30% black, 11% Hispanic, and 55% Caucasian. The spectrum of SBP changes on standing demonstrated that increases in SBP were as common as declines, and about 5% of participants had an increase, and 5% had a decrease of >20 mm Hg in SBP upon standing. Female sex, taller height, more advanced kidney disease, current smoking, and several drug classes were associated with larger declines in BP upon standing, while black race, higher blood levels of glucose and sodium, and heavier weight were associated with more positive values of the change in BP upon standing. Our cross-sectional results show a significant spectrum of orthostatic SBP changes, reflecting known (eg, age) and less well-known (eg, kidney function) relationships that may be important considerations in determining the optimal target blood pressure in long-term outcomes of older hypertensive patients.

Project description:Hypertension is a risk factor for the development of cardiovascular and kidney disease, but treatment can substantially reduce risks. Many patients avoid antihypertensive medications because of fear of side-effects. Although associations between antihypertensives and sexual dysfunction in men have been documented, it remains unclear whether antihypertensives are associated with sexual dysfunction in women. We conducted a cross-sectional analysis of baseline data from women in the Systolic Blood Pressure Intervention Trial (SPRINT) to evaluate the relations among class of antihypertensive medication and the outcomes: sexual activity and sexual function.SPRINT enrolled individuals 50 and older with hypertension at high risk for cardiovascular disease. A subset of participants completed questionnaires regarding quality of life, including sexual function. Antihypertensive class was determined by medications taken at baseline.Of 690 women in the quality of life subset of SPRINT, 183 (26.5%) were sexually active. There were no significant differences in sexual activity among women taking one or more antihypertensives and women not taking any. Women taking an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker had higher odds of sexual activity [odds ratio 1.66 (1.12-4.27), P?=?0.011]. Among sexually active women, the prevalence of sexual dysfunction was high (52.5%). No class of medication was associated with sexual dysfunction in the multivariable model.Angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use was associated with higher odds of sexual activity. Although prevalence of sexual dysfunction was high, no single class of antihypertensive medication was associated with sexual dysfunction.

Project description:The effect of clinic-based intensive hypertension treatment on ambulatory blood pressure (BP) is unknown. The goal of the SPRINT (Systolic Blood Pressure Intervention Trial) ambulatory BP ancillary study was to evaluate the effect of intensive versus standard clinic-based BP targets on ambulatory BP. Ambulatory BP was obtained within 3 weeks of the 27-month study visit in 897 SPRINT participants. Intensive treatment resulted in lower clinic systolic BP (mean difference between groups=16.0 mm?Hg; 95% confidence interval, 14.1-17.8 mm?Hg), nighttime systolic BP (mean difference=9.6 mm?Hg; 95% confidence interval, 7.7-11.5 mm?Hg), daytime systolic BP (mean difference=12.3 mm?Hg; 95% confidence interval, 10.6-13.9 mm?Hg), and 24-hour systolic BP (mean difference=11.2 mm?Hg; 95% confidence interval, 9.7-12.8 mm?Hg). The night/day systolic BP ratio was similar between the intensive (0.92±0.09) and standard-treatment groups (0.91±0.09). There was considerable lack of agreement within participants between clinic systolic BP and daytime ambulatory systolic BP with wide limits of agreement on Bland-Altman plots. In conclusion, targeting a systolic BP of <120 mm?Hg, when compared with <140 mm?Hg, resulted in lower nighttime, daytime, and 24-hour systolic BP, but did not change the night/day systolic BP ratio. Ambulatory BP monitoring may be required to assess the effect of targeted hypertension therapy on out of office BP. Further studies are needed to assess whether targeting hypertension therapy based on ambulatory BP improves clinical outcomes. CLINICAL TRIAL REGISTRATION:URL: http://www.clinicaltrials.gov.
