Phase contrast cine MRI of the coronary sinus can be used to measure the coronary flow reserve. Measurement of CFR may be useful to detect high risk DM patients developing future cardiovascular events.
Treatment of epicardial coronary artery disease (e.g percutaneous coronary intervention) is not perfect to improve clinical outcome of patients with coronary artery disease, as some of them have microvascular disease. Measurement of coronary flow reserve, an index of microvascular function, may be useful to detect the patients with imparired coronary microvascular function. Aggressive treatment strategy should be considered for these patients.
To close the gap above:
- Learners need to know about: Coronary flow resereve is an important index for patients with diabetes mellitus in terms of risk stratification.
- Learners need to know how to apply: Phase contrast cine MRI of the coronary sinus can be used to measure the coronary flow reserve.
- Learners need to do (perform): Measurement of CFR may be useful to detect high risk DM patients developing future cardiovascular events.
