Diastolic Dysfunction Reclassification Following Implementation of the 2025 Echocardiographic Guidelines
Key result
Applying 2025 echo criteria reclassifies diastolic dysfunction in ~52% of patients, primarily downgrading severity.
- n=99
Why the study?
Updated 2025 echocardiographic criteria for diastolic dysfunction emphasize integrated assessment and may alter classifications assigned using older criteria.
Does implementation of the 2025 echocardiographic guidelines alter the classification of diastolic dysfunction compared to older criteria in patients with previously graded diastolic dysfunction?
Key Points
- To evaluate the impact of updated 2025 echocardiographic criteria on diastolic dysfunction grading compared to previous classification standards.
- Retrospective quality improvement analysis of N=99 echocardiograms retrieved from the Syngo cardiovascular imaging platform.
- Sample included an equal cohort of 33 patients previously categorized with grade I, grade II, and grade III diastolic dysfunction.
- Studies were reassessed using integrated 2025 guidelines incorporating transmitral inflow, tissue Doppler indices, left atrial volume, tricuspid regurgitation velocity, and filling pressure estimates.
- Diastolic dysfunction grade remained unchanged in 48 of 99 patients (48.5%) and was reclassified in 51 patients (51.5%).
- Among reclassified patients, 32 of 51 (62.7%) were downgraded to a lower severity category, while 19 of 51 (37.3%) were upgraded to a higher severity category.

Structured PICO
Does implementation of the 2025 echocardiographic guidelines alter the classification of diastolic dysfunction compared to older criteria in patients with previously graded diastolic dysfunction?
P
Population
99 patients with previously graded diastolic dysfunction (33 each of grades I, II, and III) whose echocardiograms were retrospectively reassessed.
E
Exposure
Reassessment of diastolic dysfunction grading using the updated 2025 echocardiographic criteria.
C
Comparator
Original diastolic dysfunction grading using older criteria.
O
Outcome
Reclassification of diastolic dysfunction grade (proportion of patients remaining unchanged vs. reclassified to a higher or lower severity grade).surrogate
Implementation of the 2025 echocardiographic guidelines for diastolic dysfunction results in the reclassification of over half of patients, predominantly to a lower severity grade.
Key expert perspectives
Captured external expert commentary on this paper, strongest first. Original sources are linked where available.
“The updated guidelines will help physicians caring for patients with heart failure reach a timely diagnosis and decrease the need for cardiac catheterization to determine pressures in the left heart.”

“I think it's better identifying patients from a physiology standpoint that may have earlier changes in diastology that we may not have been able to identify as readily in 2016 guidelines”
Implication
May alter diastolic grading and management in routine practice; leaves open outcome validation of 2025 criteria.
Abstract
BACKGROUND: Echocardiographic grading of diastolic dysfunction influences diagnosis, risk assessment, and longitudinal management in cardiovascular disease. PROJECT RATIONALE: Updated 2025 diastolic dysfunction criteria emphasize integrated assessment of transmitral inflow, tissue Doppler indices, left atrial volume, tricuspid regurgitation velocity, and filling pressure estimates. Their implementation may alter classifications assigned using older criteria. PROJECT SUMMARY: We performed a retrospective quality improvement analysis of 99 echocardiograms obtained from Syngo, a cardiovascular imaging and structured reporting platform, including 33 patients each with previous grade I, II, and III diastolic dysfunction. Each study was reassessed using the 2025 criteria and compared with the original grade. Forty-eight patients (48.5%) remained unchanged, whereas 51 (51.5%) were reclassified. Among reclassified patients, 19 (37.3%) were reclassified to a higher severity grade and 32 (62.7%) to a lower severity grade. TAKE-HOME MESSAGES: Applying contemporary criteria changed diastolic dysfunction grading in more than half of cases, most often toward lower severity.

Khalid et al. (2026) conducted an observational in Diastolic dysfunction (n=99). 2025 Echocardiographic Guidelines criteria vs. Older diastolic dysfunction criteria was evaluated on Reclassification of diastolic dysfunction grade. Applying the 2025 echocardiographic criteria reclassified diastolic dysfunction grading in 51.5% of patients, with 62.7% of those reclassified moving to a lower severity grade.
