Brief Answer:
Yes, on the blood thinner. Do not recommend it, on the vit K2

Detailed Answer:
Greetings and welcome to HCM. I carefully read your query. I understand your concerns.

Well, it is highly recommended for a stent patient to be on a dual therapy with anti aggregant medication (aspirin + clopidogrel or prasugrel) for at least 6 months, if a bare metal stent was implanted, and for at leas 12 months, if a drug-eluting stent was implanted. The guidelines recommend so, and this is the curren approach in drug therapy after stent implantation. Clopidogrel is an anti-platelet (anti-aggregant) drug, therefore it acts by preventing a clot formation, by inhibiting platelets to adhere to each other and by breaking down the process of clot formation. Some recent data have shown encouraging outcomes about using vitamin K2 in primary and secondary prevention of the process of the coronary artery disease. Now, vitamin K has a direct adverse effect on oral anticoagulants (such as acenocoumarol or warfarin, which prevent clot formation by inhibiting the cascade of the process of coagulation), not on anti-platelets. Although this is true, since the stent was implanted, and vitamin K propagates clot formation, I would not recommend it for use, at this time. There is the conventional therapy to be taken after stent implantation, which also helps on secondary prevention of the coronary artery disease process.
Also, you should consult a pulmonologist about low saturation levels of oxygen. Maybe a spirometry may be recommended, to further clear the cause of these levels.

I hope I was helpful with my asnwer. I am happy to help, if you have follow-up questions.

Best regards,

Brief Answer:
Vitamin K not recommended

Detailed Answer:
Hi again and welcome back.

I am glad I was helpful with my answer. I would not recommend that clopidogrel should be continued. As long as 12 months have passed, this means that intra-stent blockage possibility has become less than 1%. About the vitamin K, it is not recommended, as I described in my original answer. As for the low oxygen levels, it may have a central (brain) component, which is not treatable, but supplementary oxygen has been proven really helpful. However, "stick" to the pulmonologist, because a cause to this situation has to be depicted. This is my opinion.

I hope my follow-up is helpful. If you do not have further questions, I would kindly ask you to close the discussion and rate the answer.

Kind regards,
Dr. Meriton
