![]() We also examined the association between H2FPEF scores and DD as well as the DD grades diagnosed by the 20 guidelines.Īssessment of LV diastolic function and LV filling pressure by the 20 ASE guidelinesĪs per the 2009 guidelines, 12) initially septal e′, lateral e′, and left atrial volume index (LAVi) were assessed. We aimed to evaluate the impact of the 2016 ASE/EACVI guidelines on the prevalence of DD, DD grades, and elevated LV filling pressures vis-à-vis the 2009 guidelines in a cohort of patients with preserved EF. The impact of the 2016 ASE/EACVI guidelines on the prevalence of DD grades and LVFP in patients with preserved ejection fraction (EF) without considering myocardial disease remains undefined. ![]() ![]() There is no clarity regarding which diseases and their severities constitute myocardial disease. ![]() As per the 2016 ASE/EACVI guidelines, patients with myocardial disease are considered to have DD, and the second step is used for DD grading and estimation of LVFP. 14), 15), 16) The heterogeneity in the reported prevalence of DD with the new guidelines is due to the differences in the study setting, sampling strategy, subjects studied, and consideration of ‘myocardial disease’ for diastolic function assessment. Studies have reported low but varying prevalence of DD with the 2016 ASE/EACVI guidelines. 13) A two-step algorithm incorporating a restricted number of feasible and reproducible variables was recommended. Acknowledging the complexity of the 2009 guidelines, the American Society of Echocardiography and the European Association of Cardiovascular Imaging (EACVI) jointly published an update in 2016 to simplify the diagnosis and classification of DD. 12) Due to multiple parameters, DF couldn’t be categorized reliably when the values of the parameters were discordant and not confined to a single category. In 2009, the American Society of Echocardiography (ASE) proposed the first guideline document based on an algorithmic approach incorporating multiple parameters to simplify and standardize the assessment of DF. to noninvasively estimate the likelihood of HFpEF. Recently, the H2FPEF score, comprising six clinical and echocardiographic characteristics, was proposed by Reddy et al. 9), 10) However, invasive testing is neither routinely advisable nor desirable. LVFP assessed non-invasively by echocardiography when incorporated into HFpEF diagnostic algorithms has limited ability to identify HFpEF accurately when compared to invasive testing. 6), 7), 8) Assessment of diastolic function (DF) and LVFP by echocardiography is complex and rather more difficult in patients with normal LV systolic function, requiring interpretation of multiple parameters. However, among stable people presenting with chronic dyspnea, diagnosis is challenging and relies on identifying direct or indirect evidence of elevated LVFP. 5) The diagnosis of HFpEF is straightforward when patients are acutely decompensated. 3), 4) Elevated left ventricular filling pressure (LVFP) is the main physiological consequence of DD. DD contributes to the development and progression of heart failure with preserved ejection function (HFpEF), accounting for almost one-half of patients with heart failure. 2) DD can coexist with left ventricular systolic dysfunction. 1) The prevalence of asymptomatic DD is reported to be approximately 25% to 30% in individuals over 45 years of age. Diastolic dysfunction (DD) is common, especially in the elderly, and is considered an important prognostic indicator for various cardiac diseases.
