Jeffrey, Welcome to the site and to my team! I have a similar ejection fraction and Congestive Heart Failure. Mine is called Diastolic Heart failure with preserved ejection fraction. It simply means my hearts left ventricle is stiff and unable to fill properly. There are lots of reasons for this and your Cardiologist will be able to explain your exact circumstances. The high BNP says that your heart is struggling to circulate blood. I suggest you make a list of questions for the Cardiologist. When you see them on Thursday be sure to get your questions answered. Since we are not doctors we can only address your question from our personal experience. It is always best to address your very specific circumstances with your Cardiologist. Good luck and let me know how you make out and what they wind up telling you. I am here to help support you in any way that I can. Hugs🤗
