Application of Multimodal Large Language Model in HFpEF

Summary

This study will validate the effectiveness of a multimodal large language model to screen for heart failure with preserved ejection fraction (HFpEF), comparing it with the traditional clinical standardized assessment process.

Eligibility

Inclusion Criteria:

1. Age 18-80 years, male or female;
2. Cardiology inpatients with suspected heart failure with preserved ejection fraction (cardiac ultrasound suggestive of LVEF ≥50% with at least 1 of the following: 1, left ventricular hypertrophy and/or left atrial enlargement; and 2, abnormal diastolic cardiac function);
3. Current or previous at least one symptom of heart failure, including dyspnea (including exertional dyspnea, nocturnal paroxysmal dyspnea, and telangiectasia), malaise, nausea, and bilateral lower extremity edema;
4. Voluntary participation and signed informed consent.

Exclusion Criteria:

1. Acute heart failure or acute worsening of chronic heart failure;
2. Severe coronary stenosis (≥75% stenosis) without revascularization;
3. Patients who are unable to perform exercise stress echocardiography or have contraindications to the test;
4. are participating in other clinical trials;
5. Those with severe organic pathologies of the liver, kidney, or hematologic system or those with chronic diseases;
6. Those who are unable to follow the trial procedures;
7. Those who refuse to sign the informed consent.
