Hypothesis
Is preserved coronary flow reserve (CFR) 72 hours after reperfused acute myocardial infarction (AMI) associated with less microvascular dysfunction and predictive of left ventricular functional recovery?
Conclusion
The early measurement of CFR by TDE can predict left ventricular functional recovery and the final infarct size after a heart attack.
Supporting Evidence
- The optimal CFR cut-off value of 1.75 distinguished between preserved and impaired CFR with high sensitivity and specificity.
- Patients with preserved CFR had better left ventricular ejection fraction and smaller final infarct size.
- Statistical analysis showed significant differences in wall motion score index between preserved and impaired CFR groups.
Takeaway
Doctors can check how well the heart is recovering after a heart attack by measuring blood flow in the heart. If the blood flow is good, the heart is likely to heal better.
Methodology
CFR was assessed by transthoracic Doppler echocardiography in 44 patients after successful percutaneous coronary intervention during the acute AMI phase.
Limitations
The study had a relatively small number of patients and the success rate of obtaining diastolic flow varied by artery.
Participant Demographics
44 patients (6 women and 38 men, aged 25 - 65 years) with first anterior STEMI.
