Systolic blood pressure, heart rate, and outcomes in patients with coronary disease and heart failure.

ABSTRACT: AIMS:Data regarding the optimal systolic blood pressure (SBP) and heart rate (HR) for coronary artery disease (CAD) patients with hypertension and a history of heart failure (HF) are limited. Accordingly, using data from a large clinical trial, we investigated the association between SBP and heart rate and subsequent adverse outcomes in CAD patients with a history of HF, and we aimed to better understand how pre-existing HF impacts outcomes among patients with CAD. METHODS AND RESULTS:Among 22 576 CAD patients enrolled in the INternational VErapamil SR-Trandolapril STudy (INVEST), 1256 were identified with a history of physician-diagnosed HF New York Heart Association (NYHA) Class 1-3 at entry. The primary outcome was the first occurrence of all-cause death, myocardial infarction (MI), or stroke. Cox proportional-hazards models adjusted for pre-specified covariates were constructed to estimate risk among the HF cohort compared with a case-matched sample from the non-HF cohort. At a mean 2.5 years' follow-up, those with prior HF had a higher risk of the primary outcome (hazard ratio (HR) 2.55, 95% confidence interval 2.30-2.83, P < 0.0001). Among those with history of HF, a low (<120 mmHg) or high (>140 mmHg) SBP and heart rate ? 85 b.p.m. were associated with increased risk for adverse outcomes, which persisted after covariate adjustment. CONCLUSIONS:In patients with CAD, a physician diagnosis of HF at baseline portended a higher risk for death, MI, or stroke than in those without an HF history. Achieving SBP of 120-140 mmHg and heart rate < 85 b.p.m. was associated with a better outcome in patients with known HF and CAD.

Project description:Importance:Lower systolic blood pressure (SBP) levels are associated with poor outcomes in patients with heart failure. Less is known about this association in heart failure with preserved ejection fraction (HFpEF). Objective:To determine the associations of SBP levels with mortality and other outcomes in HFpEF. Design, Setting, and Participants:A propensity score-matched observational study of the Medicare-linked Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF) registry included 25 354 patients who were discharged alive; 8873 (35.0%) had an ejection fraction of at least 50%, and of these, 3915 (44.1%) had stable SBP levels (≤20 mm Hg admission to discharge variation). Data were collected from 259 hospitals in 48 states between March 1, 2003, and December 31, 2004. Data were analyzed from March 1, 2003, to December 31, 2008. Exposure:Discharge SBP levels less than 120 mm Hg. A total of 1076 of 3915 (27.5%) had SBP levels less than 120 mm Hg, of whom 901 (83.7%) were matched by propensity scores with 901 patients with SBP levels of 120 mm Hg or greater who were balanced on 58 baseline characteristics. Main Outcomes and Measures:Thirty-day, 1-year, and overall all-cause mortality and heart failure readmission through December 31, 2008. Results:The 1802 matched patients had a mean (SD) age of 79 (10) years; 1147 (63.7%) were women, and 134 (7.4%) were African American. Thirty-day all-cause mortality occurred in 91 (10%) and 45 (5%) of matched patients with discharge SBP of less than 120 mm Hg vs 120 mm Hg or greater, respectively (hazard ratio [HR], 2.07; 95% CI, 1.45-2.95; P < .001). Systolic blood pressure level less than 120 mm Hg was also associated with a higher risk of mortality at 1 year (39% vs 31%; HR, 1.36; 95% CI, 1.16-1.59; P < .001) and during a median follow-up of 2.1 (overall 6) years (HR, 1.17; 95% CI, 1.05-1.30; P = .005). Systolic blood pressure level less than 120 mm Hg was associated with a higher risk of heart failure readmission at 30 days (HR, 1.47; 95% CI, 1.08-2.01; P = .02) but not at 1 or 6 years. Hazard ratios for the combined end point of heart failure readmission or all-cause mortality associated with SBP level less than 120 mm at 30 days, 1 year, and overall were 1.71 (95% CI, 1.34-2.18; P < .001), 1.21 (95% CI, 1.07-1.38; P = .004), and 1.12 (95% CI, 1.01-1.24; P = .03), respectively. Conclusions and Relevance:Among hospitalized patients with HFpEF, an SBP level less than 120 mm Hg is significantly associated with poor outcomes. Future studies need to prospectively evaluate optimal SBP treatment goals in patients with HFpEF.

Project description:BACKGROUND:Intraindividual blood pressure (BP) fluctuates dynamically over time. Previous studies suggested an adverse link between greater visit-to-visit variability in systolic blood pressure (SBP) and various outcomes. However, these studies have significant limitations, such as a small size, inclusion of selected populations, and restricted outcomes. OBJECTIVES:This study investigated the association of increased visit-to-visit variability and all-cause mortality, cardiovascular events, and end-stage renal disease (ESRD) in a large cohort of U.S. veterans. METHODS:From among 3,285,684 U.S. veterans with and without hypertension and normal estimated glomerular filtration rates (eGFR) during 2005 and 2006, we identified 2,865,157 patients who had 8 or more outpatient BP measurements. Systolic blood pressure variability (SBPV) was measured using the SD of all SBP values (normally distributed) in 1 individual. Associations of SD quartiles (<10.3, 10.3 to 12.7, 12.7 to 15.6, and ?15.6 mm Hg) with all-cause mortality, incident coronary heart disease (CHD), stroke, and ESRD was examined using Cox models adjusted for sociodemographic characteristics, baseline eGFR, comorbidities, body mass index, SBP, diastolic BP, and antihypertensive medication use. RESULTS:Several sociodemographic variables (older age, male sex, African-American race, divorced or widowed status) and clinical characteristics (lower baseline eGFR, higher SBP and diastolic BP), and comorbidities (presence of diabetes, hypertension, cardiovascular disease, and lung disease) were all associated with higher intraindividual SBPV. The multivariable adjusted hazard ratios and 95% confidence intervals for SD quartiles 2 through 4 (compared with the first quartile) associated with all-cause mortality, CHD, stroke, and ESRD were incrementally higher. CONCLUSIONS:Higher SBPV in individuals with and without hypertension was associated with increased risks of all-cause mortality, CHD, stroke, and ESRD. Further studies are needed to determine interventions that can lower SBPV and their impact on adverse health outcomes.

Project description:Background The association between blood pressure control and clinical outcomes is unclear among patients with heart failure with preserved ejection fraction. Both too high and too low of systolic blood pressure (SBP) have been reported to be related to poor clinical prognosis. This study aimed to assess the association between time in SBP target range and adverse clinical events among patients with heart failure with preserved ejection fraction. Methods and Results This study was a secondary analysis of the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) trial, a randomized clinical trial that compared the efficacy and safety of spironolactone in patients with heart failure with preserved ejection fraction. Time in target range (TTR) was calculated using linear interpolation, with the target range of SBP defined as 110 to 130 mm Hg. The association between TTR with adverse outcomes was estimated using multivariable Cox regression to adjust for multiple confounders. Participants with greater TTR were younger, more likely to be White, had less comorbidities, and lower body mass index. After adjusting for multiple covariates including mean SBP, 1-SD increment (38.3%) of TTR was significantly associated with a decreased risk of primary composite end point (hazard ratio [HR], 0.81 [0.73-0.90]), as well as a lower risk of all-cause mortality (HR, 0.81 [0.73-0.90]), cardiovascular death (HR, 0.78 [0.68-0.90]), and heart failure hospitalization (HR, 0.85 [0.74-0.97]). Results were similar when participants were categorized by TTR groups. Subgroup analyses showed that the associations were more significant in young people than in the old (Pinteraction=0.028). Conclusions In patients with heart failure with preserved ejection fraction, greater time in SBP target range was statistically associated with a decreased risk of cardiovascular outcomes and mortality events beyond blood pressure level, especially among younger patients.
