Thanks for your question on Chat Doctor. I can understand your concern. You are having chest pain on exertion (climbing stairs and after doing exercise). You are also above 50 years of age with low blood pressure. Taking all these points together, we should first rule out heart diseases in your case. So consult doctor and get done 1. Blood pressure monitoring 2. ECG 3. 2d echo 4. Stress test. 5. Coronary angiography (if required). You may need cardiac supportive Chat Doctor.  Don't worry, you will be alright. But first diagnose yourself and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
