Husb has high bp, recent dx w ckd (aug creatine=1.38). his bp is usually low norm-110/65 or lower. for the past week, he has had anxiety, fast heart rate and first bp of day is 135/75, then it goes down to the norm. should we be concerned? thank you?

A beta blocker can mitigate the rapid heart rate if it's simple sinus tachycardia and keep his BP from climbing. A nephrologist should determine the cause of the elevated creatinine and also prescribe the best medications for his BP especially if proteinuria is present. If you feel he'd profit from stress management therapy by a mental health professional, persuade him to see one,also
