Welcome at HCM
    I have gone through your query and being your physician i completely understand your health  concerns.
For how long u are suffering from it? Any other associated problem? like 
diabetes ? do u have a family history of heart problems?
         Based upon your history it appear she has got systemic 
hypertension. Which drug she is taking? You should make a chart and document her BP reading four times a day . It will help your doctor to decide about the titration of the dose 
    If i am ur attending physician i will definitely look for the other associated problems. i will get her ECG along with ECHO. I will look at his 
kidney function tests as well as 
lipid profile.
   Drugs for decreasing 
cholestrol will help to decrease the sequelae of the conditions since high cholestrol precipitates coronary narrowing.
       She should have yearly baseline  ecg echo along with kidney function tests and lipid profile to elicit the extent of disease.
       As far as food  are concerned she should avoid added salt along with fatty  and oily food. 
             Meanwhile stay calm and continue with your medications
   Get well soon
 Hope your query is adequately addressed if you still have any feel free to ask
   Regards
Dr Saad Sultan
