Optimal time of dual antiplatelet therapy in patients with coronary heart disease (literature review)

However, the choice of optimal time of DAPT after PCI is still a difficult and urgent problem for the attending physician. An increase in DAPT duration after PCI correlates with a lower frequency of ischemic events. At the same time, with a longer DAPT regime, there is a more significant increase in the risks of postoperative bleeding. Hence, it is important to find a balance between the potential risks of bleeding and the expected benefits in reducing ischemic events, while taking into account the individual clinical characteristics of each patient. Intravascular imaging methods, such as intravascular coherence tomography, allow obtaining a highly informative lifetime morphological assessment of the coronary arteries, the formation of the neointima and the malposition of the implanted stent, which, in turn, can help in choosing the optimal timing of the DAPT and prevention of undesirable side events.
