Epidemiology, Pathophysiology, Diagnosis, and Therapy of Heart Failure With Preserved Ejection Fraction in Japan

Area of Science:

• Cardiology
• Internal Medicine
• Public Health

Background:

• Heart failure with preserved ejection fraction (HFpEF) presents significant global health challenges.
• Increasing prevalence is linked to aging populations and comorbidities like hypertension, diabetes, and obesity.
• Limited data exists on HFpEF specifically within Asian populations, including Japan.

Purpose of the Study:

• To review current knowledge on HFpEF epidemiology, pathophysiology, and diagnosis in Japan.
• To explore potential therapeutic strategies tailored to the Japanese population.
• To address potential phenotypic differences in Japanese HFpEF patients compared to Western cohorts.

Main Methods:

• Literature review of existing studies on HFpEF.
• Analysis of epidemiological data from Japan.
• Synthesis of current understanding of HFpEF pathophysiology and diagnosis.
• Evaluation of potential treatment options.

Main Results:

• HFpEF is an increasing health issue in Japan, influenced by demographic and comorbidity trends.
• Potential phenotypic variations between Japanese and Western HFpEF patients warrant further investigation.
• Current treatment strategies may need adaptation for the Japanese population.

Conclusions:

• Understanding HFpEF in Japan is crucial due to potential population-specific differences.
• Further research into Japanese HFpEF phenotypes could lead to targeted therapies.
• Addressing HFpEF in Japan requires a nuanced approach considering local epidemiology and patient characteristics.
