My cardio thoracic surgeon told me to jeep the top number under 130. if your doctor is not concerned or isn’t interested in keeping you below 130 I would seek a second opinion. I totally trust my doctor and I do what she says I take losartan and unless I’m stressed out my blood pressure stays around 110/70 I’m at 4.2 and I haven’t grown for the year that I’ve had it though I was stressed out in the beginning and my blood pressure kept spiking till like 180/110 and I thought I’m gonna kill myself… That can be a problem in addition to large spikes …so please get a second opinion
