This study aims to develop a new heart failure with preserved ejection fraction (HFpEF) diagnostic algorithm tailored to Asian populations, addressing limitations of current diagnostic models. Existing HFpEF diagnostic algorithms primarily target patients with dyspnea and metabolic comorbidities, such as obesity, which are more prevalent in Western populations. However, in Asian countries, HFpEF cases are less frequently associated with obesity, leading to less prominent dyspnea and more noticeable symptoms such as fatigue. By incorporating exercise stress echocardiography and focusing on early-stage HFpEF, particularly in patients with symptoms beyond dyspnea, we seek to enable early diagnosis and intervention, ultimately extending healthy life expectancy and improving quality of life. The STOP-HFPEF (The Multicenter STudy On a Precise algorithm for diagnosis of Heart Failure with Preserved Ejection Fraction) study is a multicenter prospective observational investigation in Japan. Certified by the Japanese Society of Echocardiography, the study includes participants aged 20 and older who undergo exercise stress echocardiography. The primary goal is to develop a scoring model for diagnosing HFpEF in heart-failure stages A, B, and C. Secondary outcomes will assess the clinical utility of the new diagnostic score by comparing heart-failure incidence, cardiovascular events, and mortality rates.Study registration: Registered at the UMIN registry (UMIN000054565) on 1 July 2024.
