Abstract
Due to hormonal variations, heart failure with preserved ejection fraction (HFpEF) remains prevalent in women and affects almost half of the heart failure (HF) patients. Given the yearly death rate of 10-30% and the unavailability of medications targeting HFpEF, the need arises for a better understanding of the fundamental mechanisms of this syndrome. This comprehensive review explores sex-specific differences in traditional risk factors; female-specific factors that may impact HFpEF development and response to therapy, including variations in hormone levels that may occur pre- and post-menopausal or during pregnancy; and disparities in comorbidities, clinical presentation, and diagnostic challenges. Lastly, the review addresses prognostic outcomes, noting that women with HFpEF have a poor quality of life but a higher survival rate. It also discusses novel biomarkers and precision medicine, emphasizing their potential to improve early detection and personalized treatment.

Abstract
BACKGROUND Heart failure (HF) is a global growing health threat. This case-control clinical trial aimed to detect the predictive value and difference in aldosterone level between right side heart failure, heart failure with decreased ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF) and compare the efficacy and safety of adding mineralocorticoid receptor antagonist (MRA) for treatment. PATIENTS AND METHODS We recruited 151 participants, 135 HF patients divided equally into 45 patients in each group:(1) right side HF (2) HFrEF and (3) HFpEF and 16 healthy controls. Serum aldosterone, troponin and echocardiography were evaluated at the beginning of the study, three and six months after administration of MRA. RESULTS Aldosterone level was significantly greater in HF patients relative to controls. Aldosterone level can detect HF with excellent accuracy. There were significantly lower levels of aldosterone in right side HF compared to left side HF. There was a significant decrease in right ventricle dimensions, pulmonary artery systolic pressure and pulmonary artery size and significant increase in tricuspid annular plane systolic excursion after treatment in patients with right side HF. In the HFrEF group, there was a significant decrease in left ventricular end diastolic dimension and a significant increase in left ventricular EF after treatment. In the HFpEF group, there was a significant decrease in E/A and E/e' after treatment. CONCLUSIONS Aldosterone may have pathogenic role in HF. Measuring and follow-up of aldosterone levels should be considered in HF patients. MRA treatment gives a significant improvement in right side HF group.

Abstract
Aging is characterized by a progressive deterioration of physiological integrity, leading to impaired functional ability and ultimately increased susceptibility to death. It is a major risk factor for chronic human diseases, including cardiovascular disease, diabetes, neurological degeneration, and cancer. Therefore, the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences. In recent years, there has been unprecedented progress in aging research, particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes. In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases, we review the descriptive, conceptual, and interventive aspects of the landscape of aging composed of a number of layers at the cellular, tissue, organ, organ system, and organismal levels.

Abstract
Cardiovascular disease remains the leading cause of death for both men and women. The observation that premenopausal women are protected from cardiovascular disease relative to age-matched men, and that this protection is lost with menopause, has led to extensive study of the role of sex steroid hormones in the pathogenesis of cardiovascular disease. However, the molecular basis for sex differences in cardiovascular disease is still not fully understood, limiting the ability to tailor therapies to male and female patients. Therefore, there is a growing need to investigate molecular pathways outside of traditional sex hormone signaling to fully understand sex differences in cardiovascular disease. Emerging evidence points to the mineralocorticoid receptor (MR), a steroid hormone receptor activated by the adrenal hormone aldosterone, as one such mediator of cardiovascular disease risk, potentially serving as a sex-dependent link between cardiovascular risk factors and disease. Enhanced activation of the MR by aldosterone is associated with increased risk of cardiovascular disease. Emerging evidence implicates the MR specifically within the endothelial cells lining the blood vessels in mediating some of the sex differences observed in cardiovascular pathology. This review summarizes the available clinical and preclinical literature concerning the role of the MR in the pathophysiology of endothelial dysfunction, hypertension, atherosclerosis, and heart failure, with a special emphasis on sex differences in the role of endothelial-specific MR in these pathologies. The available data regarding the molecular mechanisms by which endothelial-specific MR may contribute to sex differences in cardiovascular disease is also summarized. A paradigm emerges from synthesis of the literature in which endothelial-specific MR regulates vascular function in a sex-dependent manner in response to cardiovascular risk factors to contribute to disease. Limitations in this field include the relative paucity of women in clinical trials and, until recently, the nearly exclusive use of male animals in preclinical investigations. Enhanced understanding of the sex-specific roles of endothelial MR could lead to novel mechanistic insights underlying sex differences in cardiovascular disease incidence and outcomes and could identify additional therapeutic targets to effectively treat cardiovascular disease in men and women.

Abstract
BACKGROUND The prognostic value of physical examination, its relation to quality of life, and influence of therapy in heart failure with preserved ejection fraction is not well known. METHODS AND RESULTS We studied participants from the Americas with available physical examination (jugular venous distention, rales, and edema) at baseline in the TOPCAT trial (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist). The association of the number of signs of congestion with the primary outcome (cardiovascular death or heart failure hospitalization), its individual components, and all-cause mortality was assessed using time-updated, multivariable-adjusted Cox regression analyses. We evaluated whether spironolactone improved congestion at 4 months and whether improvement in congestion was related to quality of life as assessed by Kansas City Cardiomyopathy Questionnaire overall summary scores and to outcomes. Among 1644 participants, 22%, 54%, 20%, and 4% had 0, 1, 2, and 3 signs of congestion, respectively, at baseline. After multivariable adjustment, each additional increase in sign of congestion was associated with a 30% to 60% increased risk of each outcome ( P<0.001). Spironolactone reduced the total number of signs of congestion by -0.10 ( P=0.005) signs, jugular venous distention (odds ratio, 0.60; P=0.01), and edema (odds ratio, 0.74; P=0.006) at 4 months compared with placebo. Each reduction in sign of congestion was independently associated with a 4.0 (95% CI, 2.4-5.6) point improvement in Kansas City Cardiomyopathy Questionnaire overall summary score. When assessed simultaneously, time-updated, but not baseline congestion, predicted outcomes. CONCLUSIONS In heart failure with preserved ejection fraction, the physical exam provides independent prognostic value for adverse outcomes. Spironolactone improved congestion compared with placebo. Reducing congestion was independently associated with improved quality of life and outcomes and is a modifiable risk factor. CLINICAL TRIAL REGISTRATION URL: https://www.clinicaltrials.gov .

Abstract
OBJECTIVES To evaluate the effects of an aldosterone antagonist on exercise intolerance in older adults with heart failure and preserved ejection fraction (HFpEF). DESIGN Randomized, placebo-controlled, double-blind trial. SETTING Academic medical center, Winston-Salem, North Carolina. PARTICIPANTS Older adults (N = 80, aged 71 ± 1; 80% female) with stable compensated HFpEF and controlled blood pressure (BP). MEASUREMENTS Participants were randomized into a 9-month treatment of spironolactone 25 mg/d vs placebo. Assessments were peak exercise oxygen consumption (VO2 ), 6-minute walk test, Minnesota Living with Heart Failure Questionnaire (MLHFQ), cardiac magnetic resonance imaging, Doppler echocardiography, and vascular ultrasound. RESULTS Seventy-one participants completed the trial: 37 in the spironolactone group and 34 in the placebo group. Adherence according to pill count was excellent (spironolactone 95%, placebo 97%). Mean spironolactone dose was 24.3 ± 2.9 mg/d and was well tolerated. Spironolactone significantly reduced systolic and diastolic BP at rest and peak exercise. At 9-month follow-up, baseline-adjusted peak VO2, the primary outcome, was 13.5 ± 0.3 mL/kg per minute in the spironolactone group versus 13.9 ± 0.3 mL/kg per minute in the placebo group (adjusted mean difference -0.4 mL/kg per minute; 95% confidence interval = -1.1-0.4 mL/kg per minute; P = .38). The 95% confidence intervals of spironolactone's effect on peak VO2 (-8.2% to 3.2%) excluded a clinically significant beneficial effect. There were also no significant differences in 6-minute walk distance, arterial stiffness, left ventricular (LV) mass, LV mass/end-diastolic volume, or MLHFQ score. CONCLUSION In older adults with stable compensated HFpEF, 9 months of spironolactone 25 mg/d was well tolerated and reduced BP but did not improve exercise capacity, quality of life, LV mass, or arterial stiffness.

Abstract
Although preserved ejection fraction is found in more than 50% of patients with heart failure, its acceptance as a specific clinical entity is limited. More understanding of the physiopathology, early diagnosis and medical management is needed. With no existing systematic information in the literature, the aim of this review is to provide a comprehensive overview of the new imaging techniques for diagnosing heart failure with preserved ejection fraction, particularly in the early stages of the disease, underlying the pivotal role of new technologies such as two-dimensional speckle tracking echocardiography and vascular stiffness.

Abstract
BACKGROUND Limited data exist regarding the impact of aldosterone antagonist therapy on cardiac structure and function in heart failure with preserved ejection fraction and on the prognostic relevance of changes in cardiac structure and function in heart failure with preserved ejection fraction. METHODS AND RESULTS Cardiac structure and function were assessed by quantitative echocardiography at baseline and at 12- to 18-month follow-up in 239 patients with heart failure with preserved ejection fraction (left ventricular [LV] ejection fraction [LVEF] ≥45%) enrolled in the Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist (TOPCAT) trial. The impact of spironolactone therapy on measures of cardiac structure and function was assessed in the study population overall, and change in echocardiographic measures was associated with the subsequent occurrence of the primary composite outcome of cardiovascular death, heart failure hospitalization, or aborted cardiac arrest. Spironolactone was not associated with alterations in cardiac structure and function compared with placebo. Decrease in left atrial volume at follow-up was associated with a lower risk of subsequent occurrence of the primary outcome. CONCLUSIONS Twelve to 18 months of spironolactone therapy was not associated with alterations in cardiac structure or function in patients with heart failure with preserved ejection fraction. Reduction in left atrial volume at follow-up was associated with a lower risk of subsequent occurrence of the primary composite outcome.

Abstract
BACKGROUND Heart failure with preserved left ventricular ejection fraction (HFPEF) affects about half of all patients diagnosed with heart failure. The pathophysiological aspect of this complex disease state has been extensively explored, yet it is still not fully understood. Since the sympathetic nervous system is related to the development of systolic HF, we hypothesized that an increased sympathetic nerve activation (SNA) is also related to the development of HFPEF. This review summarizes the available literature regarding the relation between HFPEF and SNA. METHODS AND RESULTS Electronic databases and reference lists through April 2014 were searched resulting in 7722 unique articles. Three authors independently evaluated citation titles and abstracts, resulting in 77 articles reporting about the role of the sympathetic nervous system and HFPEF. Of these 77 articles, 15 were included for critical appraisal: 6 animal and 9 human studies. Based on the critical appraisal, we selected 9 articles (3 animal, 6 human) for further analysis. In all the animal studies, isoproterenol was administered to mimic an increased sympathetic activity. In human studies, different modalities for assessment of sympathetic activity were used. The studies selected for further evaluation reported a clear relation between HFPEF and SNA. CONCLUSION Current literature confirms a relation between increased SNA and HFPEF. However, current literature is not able to distinguish whether enhanced SNA results in HFPEF, or HFPEF results in enhanced SNA. The most likely setting is a vicious circle in which HFPEF and SNA sustain each other.

Abstract
The primary adrenal cortical steroid hormones, aldosterone, and the glucocorticoids cortisol and corticosterone, act through the structurally similar mineralocorticoid (MR) and glucocorticoid receptors (GRs). Aldosterone is crucial for fluid, electrolyte, and hemodynamic homeostasis and tissue repair; the significantly more abundant glucocorticoids are indispensable for energy homeostasis, appropriate responses to stress, and limiting inflammation. Steroid receptors initiate gene transcription for proteins that effect their actions as well as rapid non-genomic effects through classical cell signaling pathways. GR and MR are expressed in many tissues types, often in the same cells, where they interact at molecular and functional levels, at times in synergy, others in opposition. Thus the appropriate balance of MR and GR activation is crucial for homeostasis. MR has the same binding affinity for aldosterone, cortisol, and corticosterone. Glucocorticoids activate MR in most tissues at basal levels and GR at stress levels. Inactivation of cortisol and corticosterone by 11β-HSD2 allows aldosterone to activate MR within aldosterone target cells and limits activation of the GR. Under most conditions, 11β-HSD1 acts as a reductase and activates cortisol/corticosterone, amplifying circulating levels. 11β-HSD1 and MR antagonists mitigate inappropriate activation of MR under conditions of oxidative stress that contributes to the pathophysiology of the cardiometabolic syndrome; however, MR antagonists decrease normal MR/GR functional interactions, a particular concern for neurons mediating cognition, memory, and affect.

Abstract
Heart failure with preserved ejection fraction (HFpEF) continues to be a challenging form of heart failure – one in which no therapy has yet been proven to improve outcome. Aldosterone antagonists have previously been shown to improve survival in a wide spectrum of patients with heart failure with reduced ejection fraction (HFrEF), and more recently, small trials suggested that they might have role in HFpEF patients. The effect of spironolactone on clinical outcomes in HFpEF was tested in the TOPCAT study.

Abstract
Pathophysiology of heart failure has been considered to be a damaged state of systolic function of the heart followed by a state of low cardiac output that is, systolic heart failure. Even if systolic function is preserved, left ventricular filling in diastole can be impeded and resulted in elevation of filling pressure and symptoms of heart failure. This kind of heart failure is called diastolic heart failure. Nowadays, diastolic heart failure is referred to as heart failure with preserved ejection fraction (HFpEF), whereas systolic heart failure is referred to as heart failure with reduced ejection fraction (HFrEF). In this paper, the similarities and differences between the pathogenesis and pathophysiology of diastolic and systolic heart failure were reviewed. Although diastolic heart failure is a common condition of heart failure worldwide, its pathophysiology has not been sufficiently elucidated. This is thought to be the most significant reason for a lack of established treatment methods for diastolic heart failure. We hope to proceed with future studies on this topic.

Abstract
BACKGROUND Despite the growing epidemic of heart failure with preserved ejection fraction (HFpEF), no valid measure of patients' health status (symptoms, function, and quality of life) exists. We evaluated the Kansas City Cardiomyopathy Questionnaire (KCCQ), a validated measure of HF with reduced EF, in patients with HFpEF. METHODS AND RESULTS Using a prospective HF registry, we dichotomized patients into HF with reduced EF (EF≤ 40) and HFpEF (EF≥50). The associations between New York Heart Association class, a commonly used criterion standard, and KCCQ Overall Summary and Total Symptom domains were evaluated using Spearman correlations and 2-way ANOVA with differences between patients with HF with reduced EF and HFpEF tested with interaction terms. Predictive validity of the KCCQ Overall Summary scores was assessed with Kaplan-Meier curves for death and all-cause hospitalization. Covariate adjustment was made using Cox proportional hazards models. Internal reliability was assessed with Cronbach's α. Among 849 patients, 200 (24%) had HFpEF. KCCQ summary scores were strongly associated with New York Heart Association class in both patients with HFpEF (r=-0.62; P<0.001) and HF with reduced EF (r=-0.55; P=0.27 for interaction). One-year event-free rates by KCCQ category among patients with HFpEF were 0 to 25=13.8%, 26 to 50=59.1%, 51 to 75=73.8%, and 76 to 100=77.8% (log rank P<0.001), with no significant interaction by EF (P=0.37). The KCCQ domains demonstrated high internal consistency among patients with HFpEF (Cronbach's α=0.96 for overall summary and ≥0.69 in all subdomains). CONCLUSIONS Among patients with HFpEF, the KCCQ seems to be a valid and reliable measure of health status and offers excellent prognostic ability. Future studies should extend and replicate our findings, including the establishment of its responsiveness to clinical change.

Abstract
Cardiovascular disease (CVD), including heart failure, constitutes the main source of morbidity and mortality in men and women with diabetes. Although healthy young women are protected against CVD, postmenopausal and diabetic women lose this CVD protection. Obesity, insulin resistance, and diabetes promote heart failure in females, and diastolic dysfunction is the earliest manifestation of this heart failure. To examine the mechanisms promoting diastolic dysfunction in insulin-resistant females, this investigation evaluated the impact of 8 weeks of a high-fructose/high-fat Western diet (WD) on insulin sensitivity and cardiac structure and function in young C57BL6/J female versus male mice. Insulin sensitivity was determined by hyperinsulinemic-euglycemic clamps and two-dimensional echocardiograms were used to evaluate cardiac function. Both males and females developed systemic insulin resistance after 8 weeks of a WD. However, only the females developed diastolic dysfunction. The diastolic dysfunction promoted by the WD was accompanied by increases in collagen 1, a marker of stiffness, increased oxidative stress, reduced insulin metabolic signaling, and increased mitochondria and cardiac microvascular alterations as determined by electron microscopy. Aldosterone (a promoter of cardiac stiffness) levels were higher in females compared with males but were not affected by the WD in either gender. These data suggest a predisposition toward developing early diastolic heart failure in females exposed to a WD. These data are consistent with the notion that higher aldosterone levels, in concert with insulin resistance, may promote myocardial stiffness and diastolic dysfunction in response to overnutrition in females.

Abstract
INTRODUCTION Heart failure with preserved ejection fraction (HFPEF) is a common syndrome, accounting for about 50% of all patients with heart failure (HF). Morbidity and mortality are similar to patients with HF with reduced ejection fraction (HFREF), yet no effective treatment has been identified in randomized clinical trials. AREAS COVERED This article provides an overview of the available literature regarding diagnosing established HFPEF and potential new therapeutic targets for the early diagnosis of HFPEF. Vascular dysfunction, ventricular-arterial coupling, oxidative stress, extracellular matrix regulation, chronotropic incompetence, pulmonary hypertension, exercise testing and biomarkers were taken into consideration next to conventional measurements of diastolic dysfunction. EXPERT OPINION Measuring diastolic dysfunction in HFPEF is considered important in many patients. Nevertheless, today we know that other causes besides diastolic dysfunction are also involved in the pathophysiology of many HFPEF patients and need to be investigated in order to make a correct diagnosis. Therefore, further research is required to allow better and more specific diagnostic and treatment options to reduce the morbidity and mortality for this ever-expanding HF population.

Abstract
Heart failure has become increasingly prevalent and poses a significant socioeconomic burden in the developed world. Approximately half of heart failure patients have preserved ejection fraction (HFpEF) and experience an increased morbidity and mortality attributed to the lack of effective therapies and to the presence of comorbidities. Suppression of neurohormonal activation by beta-blockers and renin-angiotensin-aldosterone system inhibitors is the cornerstone in the pharmacotherapy of heart failure with reduced ejection fraction (HFrEF). However, these medications are not associated with significant clinical benefit in HFpEF. In this review, we provide an in-depth pathophysiology-based update on novel pharmacotherapies of HFpEF. A deeper insight into the pathophysiologic mechanisms of HFpEF may create opportunities for novel pharmacological interventions.

Abstract
Heart failure with preserved ejection fraction (HFpEF) has recently emerged as a major cause of cardiovascular morbidity and mortality. Contrary to initial beliefs, HFpEF is now known to be as common as heart failure with reduced ejection fraction (HFrEF) and carries an unacceptably high mortality rate. With a prevalence that has been steadily rising over the past two decades, it is very likely that HFpEF will represent the dominant heart failure phenotype over the coming few years. The scarcity of trials in this semi-discrete form of heart failure and lack of unified enrolment criteria in the studies conducted to date might have contributed to the current absence of specific therapies. Understanding the epidemiological, pathophysiological and molecular differences (and similarities) between these two forms of heart failure is cornerstone to the development of targeted therapies. Carefully designed studies that adhere to unified diagnostic criteria with the recruitment of appropriate controls and adoption of practical end-points are urgently needed to help identify effective treatment strategies.

Abstract
Heart failure is a heterogeneous syndrome. Approximately 30-50% of patients with heart failure have normal or near normal left ventricle function. Several epidemiological studies confirm that the prevalence of heart failure with normal ejection fraction is increasing. Given the current trends, heart failure with normal ejection fraction will become the most common form of heart failure, for which we do not currently have an evidence-based successful treatment. This article summarizes the etiology, current recommended guidelines and management options for this clinical manifestation.

Abstract
Addition of mineralocorticoid receptor (MR) antagonists to standard therapy for heart failure, kidney disease, metabolic syndrome, and diabetes is increasing steadily in response to clinical trials demonstrating clear benefits. In addition to blocking deleterious activity of MR within the heart, vessels and kidneys, MR antagonists target MR in hemodynamic regulatory centers in the brain, thereby decreasing excessive sympathetic nervous system drive, vasopressin release, abnormal baroreceptor function, and circulating and tissue pro-inflammatory cytokines. However, brain MR are also involved with cognition, memory, affect and functions yet to be determined. Understanding specific central mechanisms involved in blood pressure regulation by MR is necessary for the development of agents to target downstream events specific to central hemodynamic regulation, not only to avoid the hypokalemia caused by inhibition of renal tubular MR, but also to avoid untoward long term effects of inhibiting brain MR that are not involved in blood pressure control.

Abstract
BACKGROUND Despite increasing prevalence of heart failure (HF) in patients with preserved ejection fraction (PEF), there are no available therapies proven to reduce morbidity and mortality. Aldosterone, a potent stimulator of myocardial and vascular fibrosis, may be a key mediator of HF progression in this population and is therefore an important therapeutic target. OBJECTIVE The TOPCAT trial is designed to evaluate the effect of spironolactone, an aldosterone antagonist, on morbidity, mortality, and quality of life in patients with HF-PEF. METHODS Up to 3,515 patients with HF-PEF will be randomized in double-blind fashion to treatment with spironolactone (target dose 30 mg daily) or matching placebo. Eligible patients include those with age ≥50 years, left ventricular ejection fraction ≥45%, symptomatic HF, and either a hospitalization for HF within the prior year or an elevated natriuretic peptide level (B-type natriuretic peptide ≥100 pg/mL or N-terminal pro-B-type natriuretic peptide ≥360 pg/mL) within the 60 days before randomization. Patients with uncontrolled hypertension and those with known infiltrative or hypertrophic cardiomyopathy are excluded. The primary end point is the composite of cardiovascular death, hospitalization for HF, or aborted cardiac arrest. Key secondary end points include quality of life, nonfatal cardiovascular events, and new-onset atrial fibrillation. Ancillary studies of echocardiography, tonometry, and cardiac biomarkers will provide more insight regarding this understudied population and the effects of spironolactone therapy. CONCLUSION TOPCAT is designed to assess definitively the role of spironolactone in the management of HF-PEF.

Abstract
Dysregulation of the renin-angiotensin-aldosterone system has been associated with a number of age-related pathologies including hypertension, heart failure and chronic kidney disease. More recently, it has been suggested that alterations within the RAAS may contribute to the development of sarcopenia and subsequent decline in physical function. There is growing interest in developing interventions to prevent age-associated decline in muscle function. We postulate that inhibition of the RAAS with the mineralocorticoid antagonist spironolactone may have a role in countering the effects of physical impairment in older people by improving skeletal muscle function. Spironolactone may prevent skeletal myocyte apoptosis, improve vascular endothelial function and enhance muscle contractility by increasing muscle magnesium and sodium-potassium pumps. This article will review the literature underpinning the hypothesis that spironolactone may have a role in maintaining muscle function in older people.

Abstract
Half of patients with heart failure (HF) have a preserved left ventricular ejection fraction (HFpEF). Morbidity and mortality in HFpEF are similar to values observed in patients with HF and reduced EF, yet no effective treatment has been identified. While early research focused on the importance of diastolic dysfunction in the pathophysiology of HFpEF, recent studies have revealed that multiple non-diastolic abnormalities in cardiovascular function also contribute. Diagnosis of HFpEF is frequently challenging and relies upon careful clinical evaluation, echo-Doppler cardiography, and invasive haemodynamic assessment. In this review, the principal mechanisms, diagnostic approaches, and clinical trials are reviewed, along with a discussion of novel treatment strategies that are currently under investigation or hold promise for the future.

Abstract
BACKGROUND Heart failure (HF) with preserved left ventricular ejection fraction (HFPEF) is the most common form of HF in the older population. Exercise intolerance is the primary chronic symptom in patients with HFPEF and is a strong determinant of their reduced quality of life (QOL). Exercise training (ET) improves exercise intolerance and QOL in patients with HF with reduced ejection fraction (EF). However, the effect of ET in HFPEF has not been examined in a randomized controlled trial. METHODS AND RESULTS This 16-week investigation was a randomized, attention-controlled, single-blind study of medically supervised ET (3 days per week) on exercise intolerance and QOL in 53 elderly patients (mean age, 70±6 years; range, 60 to 82 years; women, 46) with isolated HFPEF (EF ≥50% and no significant coronary, valvular, or pulmonary disease). Attention controls received biweekly follow-up telephone calls. Forty-six patients completed the study (24 ET, 22 controls). Attendance at exercise sessions in the ET group was excellent (88%; range, 64% to 100%). There were no trial-related adverse events. The primary outcome of peak exercise oxygen uptake increased significantly in the ET group compared to the control group (13.8±2.5 to 16.1±2.6 mL/kg per minute [change, 2.3±2.2 mL/kg per minute] versus 12.8±2.6 to 12.5±3.4 mL/kg per minute [change, -0.3±2.1 mL/kg per minute]; P=0.0002). There were significant improvements in peak power output, exercise time, 6-minute walk distance, and ventilatory anaerobic threshold (all P<0.002). There was improvement in the physical QOL score (P=0.03) but not in the total score (P=0.11). CONCLUSIONS ET improves peak and submaximal exercise capacity in older patients with HFPEF.
