Only in patients with mechanical heart valves the benefits and safety of combining aspirin with VKA therapy seems obvious. So far, decisions about the combined use of aspirin and VKA are individualized in the absence of adequate data. The variation in clinical outcomes and bleeding complications suggests that extrapolating from one indication to another may not be appropriate. However, there is no consensus about additional aspirin use in the most common indications for VKA or the use of VKAs to be added to the most common aspirin indications. vitamin k is also known as what Tap the card to flip.
