Hi friend, Welcome to Health Care Magic 10 minutes and stage 4 on treadmill is a good indeed! 50% block is not that bad – but is a warning... Overweight is a risk factor Sedentary life style is another Hypertension adds up.. Family history is bad Sedentary life style is bad too So is your food habit... If you are really concerned, you Keep your weight to normal / even a little less Do regular EXERCISE – say walking or jogging - 30 minutes a day / at least 5 days in a week. Isometric exercise (like bull worker) is bad. Healthy FOOD is a must. Avoid saturated fats – coconut oil, palm oil, butter, ghee, full cream milk...Avoid junk foods in particular – French fries have palm oil / Pizza has cheese / Indian sweets are made in ghee.../ Change to Poly-un-saturated oil – like sun flower oil. / Include Mono-un-saturated oil – Olive oil. Take statin in addition – aggressive reduction of LDL to 70 mg helps. These will prevent further progression... Keep following up with your cardiologist... Take care Wishing speedy recovery God bless Good luck
