Risk factor modification is the key in preventing or delaying the onset of overt clinical heart failure. Once heart failure has been diagnosed, the prognosis of patients with HFpEF appears to be similar to that of patients with impaired systolic function. The reported rates of mortality (1 year and 5 years), readmission for heart failure, and in-hospital complications are similar between the 2 groups.[12]Owan TE, Hodge DO, Herges RM, et al. Trends in prevalence and outcome of heart failure with preserved ejection fraction. N Engl J Med. 2006 Jul 20;355(3):251-9.

Higher levels of NT-pro-BNP are associated with increased risk of all cause mortality and heart failure hospitalizations.[146]Cleland JG, Taylor J, Freemantle N, et al.

Presence of anemia might be an indicator for poor prognosis and/or increased mortality and should be treated appropriately.[147]von Haehling S, van Veldhuisen DJ, Roughton M, Babalis D, et al. Anaemia among patients with heart failure and preserved or reduced ejection fraction: results from the SENIORS study. Eur J Heart Fail. 2011 Jun;13(6):656-63.

Depression is found in 20% to 40% of heart failure patients and is associated with increased morbidity and mortality, when compared with heart failure patients without depression.[148]Rutledge T, Reis VA, Linke SE, et al.

Therefore, there is a need for screening and early intervention when depression is present.[151]Johnson TJ, Basu S, Pisani BA, et al. Depression predicts repeated heart failure hospitalizations. J Card Fail. 2012 Mar;18(3):246-52.

One study looking at comorbidities in two large cohorts of patients (one from 2002 and one from 2017) found that in the earlier cohort, cerebrovascular disease, diabetes mellitus, and chronic kidney disease (CKD) were independent predictors for adverse outcome (HF hospitalization and all-cause mortality during a total follow-up of 1.5 years), and atrial fibrillation/flutter showed a nonsignificant trend towards poor outcome. In the later 2017 cohort, the independent predictors were anemia, obesity and COPD, with CKD showing a trend towards poor outcome. Other chronic conditions included in the model were not independently associated with prognosis, however an overall higher comorbidity burden was associated with an increased risk of HF hospitalization or all-cause mortality.[18]Screever EM, van der Wal MHL, van Veldhuisen DJ, et al. Comorbidities complicating heart failure: changes over the last 15 years. Clin Res Cardiol. 2023 Jan;112(1):123-33.

A meta-analysis suggests that even a pseudonormal diastolic filling pattern is associated with an increased risk of death compared with abnormal relaxation or a normal pattern, and the risk is similar to that noted with a restrictive filling pattern.[152]Somaratne JB, Whalley GA, Poppe KK, et al. Pseudonormal mitral filling is associated with similarly poor prognosis as restrictive filling in patients with heart failure and coronary heart disease: a systematic review and meta-analysis of prospective studies.
