[|Human|] I take a 20mg of lisinopril daily and my BP stays around 120/80. The problem is when I exert (I am a land surveyor and hike in the hills a lot surveying) it feels like I immediately get out of breath and I ve been doing this a long time. I m 58, thought I was in great shape but this past year has had me sucking more wind than ever. Is my heart o.k.?
[|AI|]  Hello, Your symptoms could be related to low blood pressure or low physical performance. Nevertheless, I would recommend performing some tests to investigate other possible causes underlying your complaints: - a chest X-ray study and pulmonary function tests to investigate for a lung disorder-complete blood count for anemia- thyroid hormone levels for thyroid gland dysfunction- blood electrolytes for possible imbalance.  It is also important to closely monitor your heart rate and blood pressure values during these episodes.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
