Atrial fibrillation, hypotension, hypercoagulability, and other factors can cause strokes after surgery. Addressing postoperative management is the most important point for decreasing the rate of postoperative stroke.

Strokes can occur at any time in patients with multiple coronary risk factors. The 5-year results of the SYNTAX trial indicated a spontaneous increase in the stroke rate over time, with rates of 2.2 % at 1 year, 3.4 % at 3 years, and 3.7 % at 5 years after surgical treatment [15].
