Figure 1. Relative frequency of potentially preventable IAEs Figure 1. Relative frequency of potentially preventable IAEs. Each patient may have had more than one IAE. Six of 14 potentially preventable bleeding events were life-threatening, and 2 of 6 potentially preventable life-threatening bleeding events were intracranial hemorrhages. Figure 1. Relative frequency of potentially preventable IAEs. Each patient may have had more than one IAE. Six of 14 potentially preventable bleeding events were life-threatening, and 2 of 6 potentially preventable life-threatening bleeding events were intracranial hemorrhages. Acute coronary syndrome was defined as 2 of the following: ischemic chest pain or elevation of cardiac biomarkers or electrocardiographic changes compatible with ischemia or acute occlusion of artery during cardiac catheterization. The category “Other” included infections (4/15), congestive heart failure (2/15), pulmonary embolism (1/15), respiratory failure (1/15), pseudoaneurysm (1/15), stress test with contraindication (1/15), interhospital transfer delay (1/15), delirium (1/15), hypotension (1/15), coronary sinus dissection (1/15), and cardiogenic shock (1/15).
