Heart failure
Monitoring of patients with a diagnosis of HT
NICE recommendation - blood pressure every 5yrs
every year for patients with T2DM
Patients with a clinic blood pressure between 140/90 mmHg and 180/120 mmHg should…?
have a 24hr ambulatory blood pressure or home readings to confirm the diagnosis
why does having blood pressure taken by a doctor or nurse usually have a higher reading
white coat syndrome - defined as more than a 20/10 mmHg difference in blood pressure between clinic and ambulatory or home readings
stages of hypertension
Stage 1 Hypertension C >140/90 A/H>135/85
Stage 2 Hypertension C>160/100 A/H >150/95
Stage 3 Hypertension C>180/120
NICE recommend all patients with a new diagnosis should have
-Urine albumin:creatinine ratio for proteinuria and dipstick for microscopic haematuria to assess for kidney damage
-Bloods for HbA1c, renal function and lipids
-Fundus examination for hypertensive retinopathy
-ECG for cardiac abnormalitie
WHEN TO REFEr
BP >180/20 +
signs of accelerated hypertension
life threatening feautures
suspected phaeochromocytoma
initial management of HT
- establish a diagnosis
- investigate for possible causes and end organ damage
- advise on lifestyle
who is medical management offered to
