<s>[INST] my friend got operated for  mitteral  valve  prolapse on  june 2012. and dr prescribed tab cardivas cr 20 one no. per day and deplatt or clopikind as -75. but his B P IS 160/100   Now question is why  B P is so high and is there any side effect. if so what is the remedy . thank you [/INST] Because the heart pumping improves after the surgery, previously present hypertension may become unmasked, or it may happen unrelated to the surgery.  U you should continue both the meds prescribed and add on an antihypertensive medication to the above regime along with lifestyle changes.  Sending me last echo report, detail of surgery, and detailed history, I be able to help him /her out.  You may further contact me through Chat Doctor on Http://doctor.
