question: Doctor, Last year I had mini invasive heart surgery. My artery adjoined to the aorta was completely closed and during the operation it was again attached to the mammaria. Before surgery I had blood pressure of 140/85. After surgery my blood pressure gradually declined until it is presently 98/55. I don't smoke or drink. I am 53. I weigh 240 pounds with a low body fat percentage. I don't use medicine accept for cardio-asperin 160 once a day. Is this normal? I don't experience dizziness or weakness. I eat extremely well, vegetables and fruit, fish, chicken breast and tuna, alot of raw salads. I have concerns just the same. Thank you kindly for any advice.
