Case Study:
Hypertension
and
Diabetes
Case
Mr. MK, a 55-year-old man.
T2DM and hypertension for 10 years. Medications:
Metformin 1 g bd
Gliclazide 160 mg bd
Amlodipine 10 mg daily
Referred for further management of poorly controlled
diabetes and hypertension.
What are the possible causes for his poorly
controlled diabetes and hypertension?
• Non-compliant to diet
• Non-compliant to treatment
• Hypoglycaemia?
• Underlying infections?
• Silent ischaemia?
• Social history: Salesman
Frequent travelling
On and off missed his medications
Diet not controlled
• Family history: Mother – diabetic, on dialysis
Father – stroke (residual left hemiparesis)
On examination:
• Obese
• Weight 98 kg, BMI 35 kg/m2
• BP 160/90 mmHg
• PR 88 beats/minute
• Bilateral proliferative retinopathy
• Minimal bilateral leg oedema
• Other systemic examination: unremarkable
9.2 %
11.8 mmol/L
106 μmol/L
Investigation results:
• A1c
• FBS
• Creatinine
• e-GFR 88 ml/min/1.73 m2
• 24h urinary protein 200 mg/24h
• ECG LVH
What are the issues that need to be addressed?
1. Poorly controlled diabetes with presence of microvascular
complications
2. BP level not to target
3. Obesity could contribute to the poorly control diabetes and
HPT
4. Need to explore any morbidities associated with the
obesity (sleep apnoea, fungal infections etc)
Questions
What would be the A1c and BP target?
How would you manage him?
What would be the choices of anti-hypertensives or anti-
diabetic agents?
Glycaemic Control
• TargetA1c: ≤ 6.5%
• Add GLP1-receptor
agonist or SGLT2-
inhibitor
• Continue Metformin
Blood Pressure Control
• Target BP ≤ 135/75 mmHg
(based on ADVANCE ON
trial)
• Pharmacological approach:
– add ARB: Irbesartan 150 mg
daily (renoprotection)
• Non-pharmacological
approach
– sodium restriction
– exercise
– weight loss

Take Home Messages
• TargetA1c ≤ 6.5%
• Target BP ≤ 135/75 mmHg
• Most patients with hypertension will require two or more
antihypertensive agents to achieve their BP goals
• Pharmacological treatment should comprise a regimen
that includes either an ACEI or an ARB as first line.
