Hypothesis
What is the prevalence of dysfunctional yet viable myocardium in patients with coronary artery disease as assessed by cardiovascular magnetic resonance imaging?
Conclusion
Many patients with coronary artery disease have significant areas of viable myocardium that could influence treatment decisions.
Supporting Evidence
- 14% of evaluated segments met criteria for dysfunctional yet viable myocardium.
- 27.1% of patients had prognostically significant areas of viable myocardium.
- 18.2% of patients had functionally significant areas of viable myocardium.
Takeaway
Doctors found that a lot of heart patients have parts of their heart that are not working well but can still get better with treatment.
Methodology
The study analyzed 181 patients using cine and contrast-enhanced cardiovascular magnetic resonance imaging to assess myocardial viability.
Participant Demographics
The study included 84% male participants with a mean age of 61.5 years.
