L6: Systemic HTN (Pt 3) Flashcards
Dx of HTN
Methods of BP Measurment
- Clinic.
- Home setting (self monitoring) (inaccurate).
- ABP monitoring (in white coat HTN).
Methods of BP Measurment
- Clinic
Methods of BP Measurment
- ABPM
Methods of BP Measurment
- Out of Office Blood Pressure Measurement
Methods of BP Measurment
- White Coat & Masked HTN
Risk in White coat hypertension
- These subjects are at intermediate cardiovascular risk between normotensives and sustained hypertensives
Dx of White coat hypertension
repeated office and out-of-office BP measurements
TTT of White coat hypertension
NO treatment if there is no cardlovascular risk or (HMOD)
- But need lifestyle modification
Dx of Masked HTN
Repeated office and out-of-office BP measurements
TTT of Masked HTN
May require drug treatment aiming to normalize outof - office BP.
