Does spontaneous bleeding compared to procedure-related bleeding increase short- and long-term mortality in patients with acute coronary syndromes?
In patients with acute coronary syndromes, spontaneous bleeding carries a significantly stronger association with early mortality than procedure-related bleeding.
Major bleeding is associated with high subsequent mortality in ACS. However, this association is much stronger in the first 30 days and is strongest for spontaneous (vs. procedure-related) bleeding.
Ducrocq et al. (Sun,) studied this question.
