In her case there are certain issues which we want to know as what is her age and how long she is a hypertensive and is she taking regular medicine and her B.P. is under control or not . As her resting ECG is abnormal and TMT is borderline positive we need to rule out significant coronary artery
disease so correct advise would be go for CT angio which is noninvasive test and if positive then a catheter based angio may be required with angiplasty SOS but if negative then antihypertensive medicines with cholesterol
lowering drug eg. Atovastatin and asprin may be added. But she need to control B.P. and cholesterol with drugs and diet low salt and Low saturated and trans fats and regular walking minimum 45 min if over weight reduce weight.
