What are the predictive factors for recurrent angina during hospitalization in patients with acute coronary syndrome?
In patients with acute coronary syndrome, prior angina, heart failure, re-infarction, and heparin use predict recurrent in-hospital angina, whereas PCI and beta-blockers are associated with lower risk.
Zhao et al. (2008) studied this question.
