Hypothesis
Is there long-term improvement of regional strain in acutely ischemic myocardium following primary coronary intervention using cardiac magnetic resonance imaging?
Conclusion
The study found a long-term improvement in heart function in patients who had a heart attack and received treatment.
Supporting Evidence
- All patients showed acute myocardial edema within the reperfused territory.
- Mean myocardial salvage was 62±21% at baseline.
- The mean infarct area decreased from 20±10.2% at baseline to 14±5.7% at 1 year follow-up.
- Peak systolic midwall circumferential strain improved from -14.4±5.3% to -19.2±5.4%.
Takeaway
Doctors looked at how well the heart works after a heart attack and found that it gets better over time with the right treatment.
Methodology
The study involved 16 patients who had a heart attack and underwent cardiac MRI at baseline and one year after treatment.
Participant Demographics
Patients with acute ST elevation myocardial infarction who received primary coronary intervention.
