What causes severe dyspnea?
Several triggering factors are responsible for that.
Thank you for asking on HCM!
I understand your concern and would like to explain that, all the above clinical scenario seems to be compatible with an acute decompensation of your chronic heart failure.
There are several triggering factors responsible for this deterioration, such as a possible infection, acute anemia, a recently uncontrolled arrhythmia, an acute myocardial ischaemia, an inappropriate therapy modulation or poor compliance, etc.
At this point, it is necessary to have an in hospital evaluation of the underlying triggering cause, and to have an intensive treatment, addressing the etiological factor, as well as signs of congestion and low cardiac output.
At the end, an appropriate maintenance therapy should be instituted.
Hope to have been helpful to you! Greetings! Dr. Iliri
