    Hello thanks for your responses. In fact there are two attitudes, either OAC is substituted by heparin, or OAC is not stopped before extraction when bleeding and thrombosis risks are low. someHello thanks for your responses. In fact there are two attitudes, either OAC is substituted by heparin, or OAC is not stopped before extraction when bleeding and thrombosis risks are low. some guidelines recommand not to stop OAC for simple tooth extraction procedures (1 or 2 teeth) with INR<4.

    This is fascinating. So do you find cardio patients will pay out of pocket or defer treatment which one might argue contributes to later expenses for insurance companies later?

  How the cardiac failure developed?

  I'm doing research about cardiac hypertrophy, but i'm not good at it, so who can explain the process of cardiac hypertrophy and cardiac failure(reason, pathology)? email:dinghailin123@163.com I'm doing research about cardiac hypertrophy, but i'm not good at it, so who can explain the process of cardiac hypertrophy and cardiac failure(reason, pathology)? email:dinghailin123@163.com thanks so much

  Here is a medical illustration of a less common view of the human heart. Do you have ideas about medical illustrations that can help documenting or sharing your specific research?

They can show progress of time, step-by-step instructions, see-through structures, and views that cameras just can't get.

  Are there any trials going on in exercise prescription for heart patients ?

  Exercising is one of the things that a physician advises his heart patients to do - but the "dose" of this medicine is not explained. we need to have some specific guidelines for these patients.
