The prognostic impact of diastolic dysfunction in patients with chronic heart failure and post-acute myocardial infarction: Can age-stratified E/A ratio alone predict survival?

摘要

To determine the prognostic implications of diastolic filling grades and identify whether age-stratified E/A ratio alone can identify patients at high risk of death post-AMI and HF. We hypothesized that in response to ageing and pathology, a normal E/A (>1) could be considered abnormal in patients post-AMI older than 65?years, and that in patients with symptomatic HF, a normal E/A always represents advanced diastolic dysfunction.
