Background: There have been recent publications of using the CHA2DS2VASC score as a simple tool for risk stratification of coronary/vascular patients, regardless of atrial fibrillation. We sought to investigate the predictive value of this score in a large all-comer PCI cohort.
Methods: We used the all-comer PCI database of the Rabin Medical Center and computed the CHA2DS2VASC score for all patients that underwent a PCI between 4/2004 and 8/2014, on their index PCI. Outcomes analyzed were all-cause mortality and the composite of death or non-fatal myocardial infarction.
Results: The cohort included all 11472 pts treated in that period. Mean follow up was 6.5 years (Range 4.5 months to 10.5 years). The frequency of the individual scores` components were as follows: Chf- 20.1% Htn- 74.7% Age>75- 36.7% Dm- 43.2% Stroke- 5.8% Vasc.dis.- 100% Age 65-75- 27.5% SexCategory(f)- 24.1%. The Mean score was 3.75 (+/- 1.665). The distribution of the various scores is shown in figure 1. The CHA2DS2VASC score predicted all-cause mortality and death/non-fatal MI in a significant (p<0.001) and graded manner as shown in figures 2 and 3.
Conclusion: the CHA2DS2VASC score can be used as a simple and effective tool to predict long term outcomes in patients undergoing PCI.
