Prognostic impact of mineralocorticoid receptor antagonist in patients with heart failure with preserved ejection fraction.

ABSTRACT: AIMS:This study aims to investigate the prognostic impact of mineralocorticoid receptor antagonists (MRAs) on cardiovascular events in patients hospitalized for acute decompensated heart failure with preserved ejection fraction (HFpEF; defined as left ventricular ejection fraction ?45%). METHODS AND RESULTS:A prospective multicentre cohort study was conducted in Nagano prefecture, Japan, between July 2014 and December 2018 that contained 518 consecutive HFpEF patients hospitalized for acute decompensated heart failure (HF). The primary outcome was a composite of cardiovascular death and HF readmission. We compared the incidence of cardiovascular events between patients who were prescribed with MRAs and those who were not in a propensity score matched cohort using a Cox proportional hazards regression model with a propensity score derived from 23 baseline variables. For sensitivity analysis, we conducted Cox proportional hazards regression models for the primary outcome adjusting for 16 clinically relevant variables in the crude cohort. The median age was 83 years, and 53% were female. The median left ventricular ejection fraction was 61%. During a median follow-up of 553 days, the primary outcome occurred in 192 (37%) patients. MRAs were used in 255 (49%) patients. After analysis, a matched cohort consisting of 370 patients was created. After propensity score matching, the baseline characteristics were well balanced between the two groups. The incidence of the primary outcome was significantly lower in MRA users than in non-users [32% (59/185) vs. 49% (90/185); hazard ratio (HR) 0.669, 95% confidence interval (CI) 0.482-0.929, P = 0.016]. The incidence of cardiovascular death was also significantly lower in the MRA users [11% (21/185) vs. 22% (41/185); HR, 0.563; 95% CI, 0.333-0.953; P = 0.032]. The risk of HF readmission tended to be lower in the MRA users [29% (54/185) vs. 41% (75/185); HR, 0.738; 95% CI, 0.520-1.048; P = 0.089]. MRA use was also associated with a lower risk of the primary outcome after Cox proportional hazards analysis adjusting for 16 clinically relevant variables in the crude cohort (HR, 0.710; 95% CI 0.507-0.995; P = 0.047). CONCLUSIONS:Mineralocorticoid receptor antagonist use was significantly associated with a lower risk of the primary composite outcome of cardiovascular death and HF readmission in patients hospitalized for acute decompensated HFpEF. The incidence of cardiovascular mortality was also significantly lower in these patients.

Project description:AimsFrailty is associated with prognosis of cardiovascular diseases. However, the significance of frailty in patients with heart failure with preserved ejection fraction (HFpEF) remains to be elucidated. The purpose of this study was to examine the prognostic significance of the Clinical Frailty Scale (CFS) in real-world patients with HFpEF using data from a prospective multicentre observational study of patients with HFpEF (PURSUIT-HFpEF study).Method and resultsWe classified 842 patients with HFpEF enrolled in the PURSUIT-HFpEF study into two groups using CFS. The registry enrolled patients hospitalized with a diagnosis of decompensated heart failure. Median age was 82 [interquartile range: 77, 87], and 45% of the patients were male. Of 842 patients, 406 were classified as high CFS (CFS ≥ 4, 48%) and 436 as low CFS (CFS ≤ 3, 52%). The primary endpoint was the composite of all-cause mortality and heart failure admission. Secondary endpoints were all-cause mortality and heart failure admission. Patients with high CFS were older (85 vs. 79 years, P < 0.001), predominantly female (65% vs. 46%, P < 0.001) and more likely to have New York Heart Association (NYHA) ≥ 2 (75% vs. 53%, P < 0.001) and a higher level of NT-proBNP (1360 vs 838 pg/mL, P < 0.001) than those with low CFS. Patients with high CFS had a significantly greater risk of composite endpoint (Kaplan-Meier estimated 1-year event rate 39% vs. 23%, log-rank P < 0.001), all-cause mortality (Kaplan-Meier estimated 1-year event rate 17% vs. 7%, log-rank P < 0.001) and heart failure admission (Kaplan-Meier estimated 1-year event rate 28% vs. 19%, log-rank P = 0.002) than those with low CFS. Multivariable Cox regression analysis revealed that high CFS was significantly associated with composite endpoint (adjusted HR 1.92, 95% CI 1.35-2.73, P < 0.001), all-cause mortality (adjusted HR 2.54, 95% CI 1.39-4.66, P = 0.003) and heart failure admission (adjusted HR 1.55, 95% CI 1.03-2.32, P = 0.035) even after adjustment for covariates. Moreover, change in CFS grade was also significantly associated with composite endpoint (adjusted HR 1.23, 95% CI 1.11-1.36, P < 0.001), all-cause mortality (adjusted HR 1.32, 95% CI 1.13-1.55, P = 0.001) and heart failure admission (adjusted HR 1.15, 95% CI 1.02-1.30, P = 0.021).ConclusionsFrailty assessed by the CFS was associated with poor prognosis in patients with HFpEF.

Project description:AimsWe sought to compare the generalizability and prognostic implications of heart failure with preserved ejection fraction (HFpEF) scores (HFA-PEFF and H2 FPEF score) in Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) and Phosphodiesterase-5 Inhibition to Improve Clinical Status and Exercise Capacity in Heart Failure with Preserved Ejection Fraction (RELAX) trial participants and matched controls from the Atherosclerosis Risk in Community (ARIC) study.Methods and resultsBased on the respective scores, the study participants from the TOPCAT (N = 356), RELAX (N = 216), and ARIC (N = 379) studies were categorized as having a low, intermediate, or high likelihood of HFpEF. Age, sex, and race matched controls free of cardiovascular disease who had unexplained dyspnoea were used to evaluate the diagnostic performance. The prognostic value of scores was assessed using multivariable-adjusted Cox regression analyses. The median HFA-PEFF scores in the TOPCAT, RELAX, and ARIC studies were 5.0 [interquartile range (IQR): 5.0-6.0], 4.0 (IQR: 2.0-4.0), and 3.0 (IQR: 2.0-4.0), respectively. The median H2 FPEF scores in the three studies were 5.5 (IQR: 4.0-7.0), 6.0 (IQR: 4.0-7.0), and 3.0 (IQR: 2.0-5.0), respectively. A low HFA-PEFF and H2 FPEF score can rule out HFpEF with high sensitivity (99.5% and 99.6%, respectively) and negative predictive value (95.7% and 98.3%, respectively). A high HFA-PEFF and H2 FPEF score can rule-in HFpEF with good specificity (82.8% and 95.6%, respectively) and positive predictive value (79.9% and 90.4%, respectively). Among TOPCAT participants, the hazard for adverse cardiovascular events per point increase in HFA-PEFF and H2 FPEF score was 1.26 (95% confidence interval: 0.98-1.63) and 1.01 (95% confidence interval: 0.88-1.15), respectively. A higher H2 FPEF score was associated with lower peak oxygen intake in RELAX trial participants (adjusted P = 0.01).ConclusionsThe HFA-PEFF and the H2 FPEF scores are reliable diagnostic tools for HFpEF. The prognostic utility of HFpEF scores requires further validation in larger rigorously phenotyped populations.

Project description:BackgroundLeft atrial (LA) size is an established marker of risk for adverse outcomes in heart failure with preserved ejection fraction (HFpEF). However, the independent prognostic importance of LA function in HFpEF is not known.Methods and resultsWe assessed LA function measured by speckle-tracking echocardiography in 357 patients with HFpEF enrolled in the Treatment Of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist (TOPCAT) trial who were in sinus rhythm at the time of echocardiography. Lower peak LA strain, indicating LA dysfunction, was associated with older age, higher prevalence of atrial fibrillation and left ventricular (LV) hypertrophy, worse LV and right ventricular systolic function, and worse LV diastolic function. At a mean follow-up of 31 months (interquartile range, 18-43months), 91 patients (25.5%) experienced the primary composite end point of cardiovascular death, HF hospitalization, and aborted sudden death. Lower peak LA strain was associated with a higher risk of the composite end point (hazard ratio, 0.96 per unit of reduction in strain; 95% confidence interval, 0.94-0.99; P=0.009) and of HF hospitalization alone (hazard ratio, 0.95 per unit of reduction in strain; 95% confidence interval, 0.92-0.98; P=0.003). The association of LA strain with incident HF hospitalization remained significant after adjustment for clinical confounders, but not after further adjustment for LV global longitudinal strain and the E/E' ratio, parameters of LV systolic and diastolic function, respectively.ConclusionsLA dysfunction in HFpEF is associated with a higher risk of HF hospitalization independent of potential clinical confounders, but not independent of LV strain and filling pressure. Impairment in LV systolic and diastolic function largely explains the association between impaired LA function and higher risk of HF hospitalization in HFpEF.Clinical trial registrationURL: http://www.clinicaltrials.gov.

Project description:AIMS:This study aimed to evaluate the prognostic significance of nutritional status in post-discharge Asians with heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS:We examined the prognostic implications of body mass index (BMI) and nutritional markers among consecutive patients hospitalized for HFpEF. Nutritional metrics were estimated by serum albumin (SA), prognostic nutritional index (PNI), Controlling Nutritional Status (CONUT) score, and geriatric nutritional risk index. Among 1120 patients (mean age: 77.2 ± 12.6 years, 39.4% men), mean SA levels, PNI, CONUT scores, and geriatric nutritional risk index were 3.3 ± 0.6 g/dL, 40.2 ± 8.7, 5.5 ± 2.1, and 95.9 ± 14.5, respectively. Lean body size, higher white blood cell counts and C-reactive protein levels, anaemia, and lack of angiotensin blocker use were independently associated with malnutrition (defined by SA < 3.5 g/dL). Higher SA levels [hazard ratio (HR): 0.67 (95% confidence interval, CI: 0.53-0.85)], higher PNI [HR: 0.97 (95% CI: 0.95-0.99)], and higher geriatric nutritional risk index [HR: 0.98 (95% CI: 0.97-0.99)] (all P < 0.05) were all associated with longer survival, with higher CONUT score [HR: 1.08 (95% CI: 1.02-1.13)] exhibited higher mortality in Cox regression models and with higher SA levels/PNI but not BMI further contributing to the reduced rate of re-hospitalization (both P < 0.05). Categorizing BMI (25 kg/m2 as cut-off) and nutritional status showed significantly higher mortality rates among patients with lower BMI/malnutrition than among those with BMI/better nutrition (SA level, PNI, and CONUT score, all P < 0.01). Restricted cubic spline regression revealed a marked survival benefit of better nutrition with increasing BMI (adjusted Pinteraction for both SA level and PNI: <0.001; adjusted Pinteraction for CONUT score: 0.046). CONCLUSIONS:Malnutrition was frequently and strongly associated with systemic inflammation in Asian patients hospitalized for acute HFpEF. Our findings also indicate that nutrition may play a pivotal role in metabolic protection in this population.
