1
Q

Under what circumstances/which patients should you initiate anti-hypertensives?

A
  • All patients w/ Stage 2 HTN
  • Patients w/ Stage 1 HTN w/ 1+ of the following:
    • ASCVD (atherosclerotic cardiovascular disease)
    • DM type 2
    • CKD (chronic kidney disease)

Q

Patients over age 60 yrs w/ isolated systolic HTN, what BP value do you need to be careful with?

Why?

A
  • CAUTION, do not lower DBP <55 to 60 mmHg
  • Low DBP is assocated w/ increassed risk of MI and stroke
