I have not heard of albuterol causing PH but I know that Aspartame can and come to think of it, sometimes i think it has some of it in albuterol. I know that may be a reason but I am not sure. Usually there are other reasons that you develop a sudden case of PH and that is usually related to some other cause. Are you sure you did not have any other heart/lung problems before? I am hoping we get a response to your question. I wish you the best of luck.
