Both give foot pain on walking
SS - Relieved by leaning forwards, may also be weakness, may be minimal CVD risk factors
PAD - Standing still (without leaning forward) relieves pain. No weakness or numbness
38
A patient presents with intermittent claudication, how do you manage?
1st line - Exercise programme
- If not keen for this, or not worked - refer for angioplasty/ bypass

The most predictive sign is cool skin in those with leg symptoms.
Combination of signs does not increase the chance of diagnosis, so take any single sign seriously in PAD

1) Assess stroke (CHADSVASC) and bleed (ORBIT)
2) Start on anticoagulation if appropriate (Apixaban)
3) Rate control with beta blocker (1st) or calcium channel blocker

If not sending to medical SDEC or similar review within 1 week of starting rate control
AF review at least annually
56
What are DVLA guidelines for AF?

Also check age and weight to see if dosing is correct
58
A 63-year-old woman has type 2 diabetes. She has normal renal function and her blood pressure is 128/78 mmHg.

Gliclazide
(As she has symptoms)
MODY causes reduced insulin secretion and symptoms may not be severe. First-line treatment aims to stimulate the pancreas, and most patients with MODY are very sensitive to sulfonylureas.

- Nephropathy
- Other CV risk factors
CONSIDER statins for ALL other adults with type 1 diabetes
66

Do NOT do risk calculation: age alone puts them at increased risk, particularly if
they smoke or have raised BP
CONSIDER atorvastatin 20mg
67
How many HbA1c results are needed to diagnose pre-diabetes?
1 test only
(T2DM needs two HbA1c results whereas pre-diabetes only needs 1)
68

Coronary artery vasospasm
- Angina occuring at rest, usually 5-30mins, usually between midnight and early morning - can be triggered by stress/ alcohol etc
- Can present very similar to MI so always send into secondary care same day
79
Is white coat hypertension the same when patients see all practioners?
The white coat effect is smaller for blood pressure measurements made by nurses than by doctors.
80
For patients with stable coronary artery disease on antihypertensive treatment, which SINGLE range of blood pressure is associated with the LOWEST rate of cardiovascular events and mortality?
120/70 - 139/79
Blood pressures of under 120 systolic and 70 diastolic, are associated with an increased rate of cardiovascular events. Blood pressures of 140 systolic and over or 80 diastolic and over are also associated with an increased rate of cardiovascular events. This is a ‘J shaped curve’.
81
You see a 63-year-old patient with known atrial fibrillation awaiting a hernia repair procedure.
What is the SINGLE MOST important primary objective for GPs optimising patients with atrial fibrillation for surgery? Select ONE option ONLY:
Rate control/ rhythm control, INR control, managing anticoagulants, managing other co-morbidity
Rate control
Typically a heart rate of 60-80 at rest is considered optimal, and heart rates exceeding 90 beats per minute require further management in line with usual practice.
Patients should expect to receive clear instructions from preoperative assessment clinic about anticoagulants or antiplatelets in the immediate perioperative period as they have prime responsibility for this.
82

- Over 55/ black < Thiazide before ACEI
85
For the purposes of selecting hypertensive drugs, which patients are considered to be black?
Black patients are considered to be those of African or Caribbean descent, not mixed-race, Asian or Chinese.
86
Which are the 4th line add-on medication options for the treatment of drug-resistant hypertension?
K+ 4.5 or less = Add spironolactone (first choice)
K+ > 4.5 - Doxazosin (only if spiro contraindicated) or beta blocker
87
If a patient has microvascular angina, which drugs should be initiated as secondary prevention treatment?
Patients with microvascular angina have been found to have normal coronary arteries at angiography. The National Institute for Health and Care and Excellence (NICE) recommends that patients are not routinely offered the usual secondary prevention treatment.
88
How is ABPI performed?
The ankle brachial pressure index (ABPI) is the ratio of the highest recorded systolic pressure recorded in the affected leg over the highest recorded systolic pressure in either arm.
(So in PAD expecting leg to be lower pressure than arm, if leg pressure is significantly higher than arm this suggests calcification)
89
