Abstract
from our study we can conclude:
1. CHA2DS2VASc score is simpler and easier to calculate which is proved to be independent predictor of MACE and mortality in short-term follow up of STEMI patienIts.
2. CHA2DS2VASc score can be used as a risk stratification system in patients with STEMI.
3. The 3 risk scores (TIMI, GRACE, and CHA2DS2VASc) were able to discriminate patients with Acute STEMI with or without MACE at different time points up to 6ms with non-significant difference between them in prediction of short-term cardiovascular events after STEMI.
4. People with high CHA2DS2VASc score tended to be older with more co-morbidity, and these factors might affect patient selection for invasive strategy; they were less likely to undergo revascularization than those with low or intermediate risk score.
Recommendations
1. Another study on a larger number of populations is needed to be done to give a more accurate and conclusive results.
2. Another study that include both STEMI and NSTEMI patients with known AF and compare between both of them.
3. A Multi-center study is recommended to detect more accurate data that could be applied to general population.
4. Cardiac event-free survivals are recommended to compare the three groups.
