Effect of Inorganic Nitrite vs Placebo on Exercise Capacity Among Patients With Heart Failure With Preserved Ejection Fraction: The INDIE-HFpEF Randomized Clinical Trial. In a small, single center study, catheter ablation of atrial fibrillation improved diastolic function in patients who maintained sinus rhythm[77]. During submaximal exercise, patients with HFpEF display pulmonary artery wedge pressures > 25 mmHg or an increase of 7 3 mm Hg above the resting measurement, and pulmonary artery systolic pressures 45 mmHg in contrast to patients with noncardiac dyspnea[57,58]. This article is an open-access article which was selected by an in-house editor and fully peer-reviewed by external reviewers. Revascularization should be considered for patients with heart failure with preserved ejection fraction and coronary artery disease. Prognosis after the first hospitalization for HFpEF is poor, with one-year mortality rates as high as 25% among older patients and five-year mortality rates of 24% among patients older than 60 years and 54% among those older than 80 years.33,34 Patients with HFpEF fare worse than age- and sex-matched controls and have reported mortality rates similar to or better than patients with heart failure with reduced ejection fraction.35,36 Factors associated with worse prognosis include higher levels of NT pro-BNP, older age, diabetes, history of myocardial infarction or chronic obstructive pulmonary disease, reduced glomerular filtration rate and diastolic function, and right ventricular remodeling.3638, This article updates previous articles on this topic by King, et al.39 ; Satpathy, et al.40 ; and Gutierrez and Blanchard.41. No difference between groups in all-cause hospitalization or mortality; fewer patients in the nebivolol group had the combined outcome of all-cause mortality and CV hospitalization (31.1% vs. 35.3%; NNT = 24; Study of Effects of Nebivolol Intervention on Outcomes and Rehospitalization in Seniors with Heart Failure (SENIORS) trial (post hoc analysis), 752 patients with clinical HF (hospital admission for HF in previous 12 months) and LVEF > 35% (mean EF of 49%), No difference between groups in all-cause hospitalization or mortality, or combined all-cause mortality and CV hospitalization, Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, 3,446 patients with HF symptoms, LVEF 45%, and hospitalization in previous 12 months. Comparison of -blocker effectiveness in heart failure patients with preserved ejection fraction versus those with reduced ejection fraction. No evidence supports a rhythm-control strategy unless rate control does not control symptoms.3,5 Complete revascularization is associated with improved mortality in patients with HFpEF and CAD who meet criteria for revascularization.3,30, Hospitalized patients with HFpEF should be treated similarly to those with heart failure with reduced ejection fraction (diuretics and supportive measures).
In this regard, diuretic drugs are effective for blood pressure control and for the prevention of volume overload. The annual mortality rate of these patients is 8%-12% per year.

Heart Failure With Preserved Ejection Fraction In Perspective. Class I recommendation (Level of Evidence: A) for measurement of baseline natriuretic peptide biomarkers and/or cardiac troponin on admission to the hospital to establish a prognosis in acutely decompensated HF.
Patients with HFpEF and symptoms of volume overload should be treated with diuretics.31 Hypertension should be treated according to appropriate guidelines.3 Although RCTs of several medications showed fewer heart failure hospitalizations, this benefit was offset by increases in hospitalizations for other reasons. Patients presenting with symptoms concerning for heart failure should undergo clinical evaluation. More than 80% of patients with heart failure with HFPEF, are overweight or obese and deconditioned. Myocardial stiffness in patients with heart failure and a preserved ejection fraction: contributions of collagen and titin. Hypertension in patients with HFpEF should be treated according to evidence-based hypertension treatment guidelines. This includes those with elevated brain natriuretic peptide levels or physical examination findings suggestive of heart failure, and those who meet the Framingham, MICE (Male, Infarction, Crepitations, Edema), or Netherlands criteria for heart failure. Author contributions: The author finished manuscript alone. Patients with HFpEF should be referred for endurance and resistance training. Community-based studies show that coronary heart disease (CAD) is common in HFpEF, and is present in 40% to 60% of patients with HFpEF[60-62]. A systematic review found that normal electrocardiography findings reduced the likelihood of heart failure (pooled LR = 0.19).7 However, normal chest radiography was less helpful for excluding heart failure (LR = 0.38), and moderately helpful for confirming it (LR+ = 4.1).7 Neither electrocardiography nor chest radiography significantly improved the accuracy of diagnostic models when natriuretic peptide results were available.9,10 Nonetheless, electrocardiography is necessary in patients with suspected heart failure to assess for evidence of CAD, left ventricular hypertrophy, and dysrhythmia.3,5, A large, prospective, primary carebased study compared seven sets of diagnostic criteria in patients who had heart failure with preserved or reduced ejection fraction.11 It showed that most criteria had LRs+ that increased the likelihood of diagnosing heart failure, but none reliably excluded it. Digoxin should also be avoided in patients 65 years and older who have HFpEF. In this regard, Inflammation can cause the release of TGF- from fibroblasts and monocytes/macrophages, which induce the differentiation of fibroblasts into collagen-producing myofibroblasts, while simultaneously decreasing matrix metalloproteinase (MMP)-1 and the tissue inhibitor of (MMP)-1[17,31,32]. Spironolactone for heart failure with preserved ejection fraction. Patients with obesity, hypertension, atrial fibrillation, and volume overload require weight reduction, an exercise program, aggressive control of blood pressure and heart rate, and diuretics. Patients with ECV > 30% had decreased event-free survival during the subsequent four years. Consequently, patients with HFpEF should be subcategorized according to the presence or absence of CAD. A Test in Context: E/A and E/e' to Assess Diastolic Dysfunction and LV Filling Pressure. Comorbid atrial fibrillation or CAD should be treated. CMR determined ECV measurements provide risk stratification for HFpEF during the ensuing four years. Understanding heart failure with preserved ejection fraction: where are we today?

Zile MR, Brutsaert DL. Class I recommendation (Level of Evidence: C-LD) for titration of GDMT to attain SBP <130 mm Hg in patients with HFpEF and persistent hypertension after management of volume overload. Core tip: Three million people in United States have heart failure with normal left ventricular systolic function but abnormal diastolic function due to increased myocardial stiffness. Figure Figure11 summarizes the different factors that can contribute to HFpEF. Furthermore, two recent retrospective studies report that the long-term treatment with a mineraloreceptor antagonist, such as spironolactone or eplerenone, and a beta-adrenergic receptor blocker drugs is associated with a reduction in the incidence of new-onset HFpEF in patients with hypertension[9,71,72]. In addition, abnormal cardiomyocyte sodium-calcium exchange and also calcium leak from the sarcoplasmic reticulum increase cardiomyocyte diastolic cytosolic calcium concentrations, which increases cardiomyocyte resting tension in HFPEF patients due to a delayed inactivation of actin-myosin crossbridges[26,27]. SGLT2 inhibitors, such as empagliflozin, promote gylcosuria and diuresis by reducing glucose and sodium absorption in the proximal renal tubule, without activating the sympathetic nervous system. The specific conditions that can contribute to HFpEF are listed in Table Table11 which is adapted in part from[7,8].
In addition, since many hospitalizations and deaths in patients with HFpEF are due to noncardiovascular causes such as chronic obstructive lung, chronic kidney disease, and diabetes, these disorders must be identified early in the clinical course and aggressively treated. The use of nitrates, spironolactone, and angiotensin receptor blockers should be avoided in patients with HFpEF.
