[|Human|] Hi, may I answer your health queries right now ? Please type your query here... My brother is 55 yrs old. For the last 2 months, he is suffering from breatlessness when he walks 100 ft. Then he has to take rest for 5 mts and walk again. This has to be repeated every 100 ft. He has a little high BP now. He never had BP problem earlier. He is taking medicine for that.One cardiologist has advised him to go for angio.Is it necessary
[|AI|]  Hello, An exercise cardiac stress test would be a less invasive test to help investigate for possible coronary artery disease.  If this test results abnormal, you can proceed to cardiac angiography, which is a more invasive and expensive test.  I would also recommend checking the complete blood count for anemia and pulmonary function tests in order to exclude a lung disorder, which could mimic this clinical situation.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
