Hi,
Thanks for using Healthcaremagic,
I can appreciate the apprehension you are going through due to your symptoms and recent death of your brother.
You are also 65 years you should get full medical check up to see status of your health and treat accordingly. You will certainly find Cardiologist and medical centre where you can be investigated and taken care.
You should be examined by Cardiologist and investigate like
Complete blood count, Fasting blood sugar, Post prandial blood sugar,
Lipid profile, Liver Kidney function, Uric acid, 12 Lead EKG, 2 D
echocardiography, X ray chest , Lung function tests and
Stress test.
Further tests depend on result of investigations.
If required Coronary
angiography may be done.
Regular physical exercise, taking care of diet, avoiding alcohol and smoking if there.
Hope this helps
Take care
Good Luck
Dr.Akhilesh Dubey M.D.
