Long Term Complications Flashcards
What are the 2 classifications of complications?
- Macrovascular affecting large vessels
- Microvascular affecting small vessels
What are the complication risk factors?
- Duration of diabetes
- Metabolic control
- Smoking
- Hypertension
- Hyperlipidaemia
- Genetics
What is the main cause of death in diabetes?
Cardiovascular macrovascular disease
How does diabetes affect your risk of MI?
Increases by 2-5x with higher mortality and morbidity post MI
How does diabetes affect your risk of stroke?
Increases by 3x
How does diabetes affect your risk of peripheral arterial disease?
Increase by 5x
Describe peripheral arterial disease..
- A diffuse distal disease
- x40 fold increased risk of amputation
What are the cardiovascular risk factors?
- Glucose control
- Blood pressure
- Smoking
- Lipids
- Proteinuria
- Family history
- Gender
What primary prevention is there to reduce CV risk?
- Target HbA1c 53mmols/mol
- Control BP to <130/80
- Smoking cessation
- Statin therapy
- Lifestyle choices
Give examples of microvascular diseases.
- Retinopathy
- Neuropathy
- Nephropathy
What is microvascular disease?
Disease of the arterioles and capillaries
What is diabetic the commonest cause of?
Blindness in working age population
How can diabetic retinopathy be prevented?
- Good glucose control
- Tight BP control
- Early detection and intervention
Give examples of types of diabetic retinopathy.
- Background retinopathy
- Proliferative retinopathy
- Maculopathy
Give examples of retinal abnormalities in diabetes.
- Microaneurysms (dots)
- Blot haemorrhages
- Hard exudates
- Cotton wool spots
- New vessel formation
- Vitreous haemorrhage
- Advanced eye disease
How is proliferative retinopathy treated?
- Laser photocoagulation (destruction of peripheral ischaemic retina leads to reduction of endothelial growth factors and regression of new vessels)
- Vitrectomy
What are the features of diabetic maculopathy?
- Exudates and blot haemorrhages at macula
- Macular ischaemia
- Macular oedema deforms the macula
- Decrease in visual acuity is common in type 2 diabetes
What is the treatment for diabetic maculopathy?
- Grid laser therapy
- Tight control of blood glucose
- Tight control of BP
Who re cataracts common in?
- Elderly
- 2 fold increase in diabetes
- Those with poor glycaemic control
What dictates when surgery is carried out for cataracts?
Visual acuity
What types of diabetic neuropathy are there?
- Peripheral neuropathy (diffuse nerve disease)
- Mononeuritis (single nerve palsy)
- Autonomic neuropathy
