Q

screening for HTN

A
  • All adults should have their BP measured at least every 5 years up to the age of 80 and annually there after
  • Diagnosis of hypertension is confirmed if a person has:
    • A clinic blood pressure of 140/90 mm Hg or higher; and
    • ABPM daytime average or HBPM average of 135/85 mm Hg or higher.
    • Target organ damage screening: hypertensive retinopathy, left ventricular hypertrophy, blood tests, urinalysis for albuminuria, proteinuria and haematuria

17
Q

Step 1: pt with evidenc eof HF

A

(D)

  • thiazide-like diuretic e.g. idnapmide
18
Q

which antihypertensive should not be use din conjunction with diabetes

A

CCB

ACE inhibitors and ARBs are preferred agents in the management of patients with hypertension and diabetes

19
Q

Step 2 choices for hypertension

A

check person is compliant with step 1

  • if initially started on:
    • ACEi or ARB + CCB or D
    • CCB or D + ACEi or ARB
20
Q

which antihypertensive should not be used in black people

A

ACEi

ARB is preffered

21
Q

step 3 choices for hypertension

A

use ACEi or ARB and a CCB and thiazide like diuretic

22
Q

step 4 choices for hypertension

A
  • reistant hypertension
  • discuss adherence
  • add 4th antihypertensive
  • consider referral
  • consider further diuretic with low dose spironolactone
23
Q

Chronic kidney disease

Classification

A

Kidney function should be assessed using a combination of GFR and albumin:creatinine ratio (ACR) categories.

  • Increased ACR and decreased GFR are associated with increased risk of adverse outcomes.
  • Increased ACR and decreased GFR in combination multiply the risk of adverse outcomes.
24
Q

causes of CKD

A
  • Diabetes
  • Hypertension
  • Glomerular disease
  • Acute kidney injury
  • Nephrotoxic drugs e.g. ACEi, ARB, NSAIDS
  • Myeloma]family history
  • Obesity
  • Gout
25
Q

presentation of CKD

A
  • Symptoms (severe)
    • Anorexia
    • Nausea
    • Fatigue
    • Weakness
    • Pruritus’
    • Peripheral oedema
    • Dyspnoea
    • Insomnia
    • Nocturia/polyuria
    • Signs
      • Hypertension
      • Excoriation
      • Pallor
      • Peripheral oedema
26
Q

screening for CKD

A

monitor GFR annually

27
Q

investigations for CKD

A
  • Blood pressure
  • Urine analysis
    • Protein in urine?
  • Blood tests
    • Urea and electrolytes
    • eGFR
    • Bone biochemistry
    • Liver function tests (albumin)
    • Full blood count
    • CRP
    • +/- iron levels (ferritin, iron, reticulocyte haemoglobin)
    • +/- PTH
28
Q

further investigations for CKD

A
  • Auto-antibody screen (auto-immune)
  • Ultrasound
    • Kidney size
    • Evidence of obstruction (hydronephrosis)
    • Kidney biopsy
      • Cause unknown
      • Haematuria
      • Proteinuria
    • More specific investigations- CT (stones/mass), MRI (mass), MR angiogram
29
Q

management of CKD is outpatient based

A
  • treat underlying disease
  • reduce CVD risk
  • reduce progression of CKD
  • prevent or treat complications of CKD
30
Q

treating underlying disease in CKD

A
  • Treat and monitor diabetic control
  • Treat hypertension
  • Treat infections promptly
  • Tolvaptan if meets criteria for ADPKD
  • Immunosuppression for GN if appropriate
31
Q

reducing CVD risk in CKD

A
  • Start on statin
  • Control BP
  • Improve control of diabetes
  • Advise weight loss
  • Advise exercise
  • STOP SMOKING
32
Q

reducing progression of CKD

A
  • Reduce proteinuria – ACEi/ARB
  • Monitor blood tests
  • Control BP
33
Q

prevent or treat complications of CKD

A
  • Dietary advice regarding low phosphate/low potassium diet
  • Phosphate binders
  • IV Iron/Folate/Vit B12 replacement
  • EPO (Erythropoesis stimulating agent)
  • Replace Vitamin D deficiency
  • Consider Calcimimetics for tertiary hyperparathyroidism
  • Dietician input
34
Q

hyperlipidaemia

A
  • Rised serum levels of one or more of total cholesterol (TChol), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), or both TChol and TG (combined hyperlipidaemia).
  • Dyslipidaemia is a wider term that also includes low levels of high-density lipoprotein cholesterol (HDL-C). Many types of hyperlipidaemia carry an increased risk of cardiovascular disease (CVD).
35
Q

cholesterol should be

A

<5

36
Q

causes of hyperlipidaemia

A
  • Poor diet (eating too much saturated or trans fat), obesity, lack of exercise, smoking, alcohol and increasing age.
  • Familial hypercholesterolaemia is an inherited autosomal dominant condition. This should be suspected in adults with a total cholesterol level greater than than 7.5mmol/L and/or a personal or family history of premature coronary heart disease, an event before 60 years in an index person or first degree relative.
37
Q

presentation of hyperlipidaemia

A
  • No symptoms
  • Signs: corneal arcus, Xanthelasma
38
Q

investigations for hyperlipidaemia

A
  • Lipid profile
  • FBG
  • Renal function
  • LFTS
  • TSH
  • Do QRiskScore
39
Q

Management of hyperlipidaemia– aim to prevent CVD

A
  • Lifestyle changes
  • First line: statins (atorvastatin, simvastatin)- inhibit HMG-CoA reductase
    • Most effective drugs (aim of <40% reduction after 3 months)
    • issue with myalgia (test for CK)
  • Adjuvants/ if statins not tolerated
    • Ezetimibe
    • Fibrates
    • Omega- 3 fish oils
40
Q

MOA or ezetimibe

A

inhibits the absorption of cholesterol from the small intestine (NPC1L1 inhibitor) and decreases the amount of cholesterol normally available to liver cells.

The lower levels of cholesterol in the liver cells leads them to absorb more cholesterol from circulation and thus lowering the levels of circulating cholesterol.
