CARDIO Flashcards
What does QRISK score evaluate
Predicts risk of CVD in upcoming 10 years
What % occlusion is required for angina symptoms
70-80%
1st and GS investigations for angina
ECG and CT angiography
1st line pharmacological treatment for Angina
Calcium Channel blocker or Beta Blocker
Percutaneous Coronary Intervention (PCI) vs Coronary Artery Bypass (CABG)
Balloon stent (PCI) is less invasive but risk of stenosis
Bypas graft better prognosis but more invasive
ECG changes after MI
Hyper Acute T wave
Pathologically deep Q waves
LBBB
Type 1 vs Type 2 MI
T1:- IHD
T2:- Increase demand or spasm
NSTEMI vs STEMI ecg changes
NSTEMI;- ST depression, T wave inversion, no Q waves
STEMI:- ST elevation, pathological Q waves after time
Treatment for MI
M:- morphine
O:- oxygen (if sats<94%)
N:- nitrogen
A:- Asprin 300mg
C:- Clopidrogrel 75mg
When should you do thrombolysis before PCI with STEMI
If been more than 12hr
Long term prevention of ACS
Beta-blocker, aspirin (initial loading dose of 300mg- 75mg), clopigdognel 75mg 12 months, atorvostatin, ACEi
Acute complications of MI
(<2 weeks)
Mitral incompetence, LV free wall rupture, Cardiogenic shock
Complication after 2 weeks for MI
Dressler syndrome (autoimmune pericarditis)
LV anyeurysm (heart becomes saggy)
Male or Female higher risk for HF
Male
NY Heart Association classes of Heart Failure
1:- No limit of physical activity
2:- Slight limit of phsical activity
3:- Marked limit on moderate/ gentle activity
4:- Symptoms at rest
What do you expect to see on CXR on someone with heart failure
ABCDE:-
Alveolar Bat wing oedema
Kerley B lines
Cardiomegaly
Dilated upper lobe vessels
Pleural Efuusion
Pharmacological treatment for hf
ABAL:-
ACEi
Beta Blocker
Aldosterone antagonist (Spironolactone)
Loop Diuretic (Furosemide)
Size requirement to be an abdominal aortic anyreusm
50% increase/ >3cm
Are AAA’s typically infrarenl or suprarenal
Infrarenal
Which layers affected in tru AAA
All 3 arterial layers
At what size does rupture risk massivley increase
> 5.5cm
Where does pain radiate to in AAA
Epigastric to flank
Most common sites for aortic dissection
1:- Sinotublar junction
2:- Just distal to left subclavian artery
What is the standard Classification of AD
A= Proximal to LSC artery 66%
B= Distal to LSC artery 33%
What does CXR show in AD
Widened mediastinum >8cm
Pharmacological treatment for AD
Special Beta Blocker, esmolol and labetolol
Htn treatment 1st line
<55 or T2DM:- ACEi (if CI ARB)
>55 or black African (CCB)
2nd+ line treatment htn
ACEi + CCB
ACEi + CCB + Thiazide like diuretic
Virchows trad component
Venous Stasis
Hypercoagulability
Endothelial Injury
Wells DVT score
<1 on dimer not raised means no DVT
>1 Duplex ultrasound Diagnostic
What is peripheral vascular disease
Essentially IHD of lower limb vessels
Six Ps of Acute limb ischemia
Pulslessness
Pallor
Pain
Perishingly cold
Paralysis
Parathesia
What is ABPI
Ankle-brachial pressure index, used in diagnossis of PVD <0.9
What does a ABPI of <0.5 mean
Chronic limb ischemia
Treatment for intermittent claudication PVD
Risk factor management
Treatment for Chronic limb ischemia
PCI/ bypass
Treatment for Acute limb-threatening ischemia
Revascularisation within 4-6 hours
Complications of PVD
Amputation, permanent limb weakness, Rhabdomydysis (CA2+ and K+ released into blood)
Most common cause of pericarditis
1:- Viral
2:- Autoimmune (SLE, Sjordens)
Symptoms/ signs of pericarditis
Sharp chest pain
Worse lying down or on inspiration
Pain radiates to left shoulder( trapiziues ridge) due to irritation of phrenic nerve
Pericardial friction rub on auscaliation
Raised ESR in autimmune
Raised WCC in infective
ECG showings of pericarditis
Saddle ST elevation
Pr depression
Treatment for idiopathic or viral pericarditis
NSAIDS(2 weeks) + Colchicine (3 weeks)
Treatment for IE with Staph Aureas
Vancomycin + rifampicin
Treatment for IE with Strep Viridans
Benzylpenicillin + Gentamicin
Best way to hear right-sided vs left-sided heart murmers
RILE
Right side on Inspiraton
Left on expiration
Causes of mitral stenosis
Rheumatic heart disease, valve calcification, IE
Symptoms of mitral stenosis, including murmur sound
Malar cheek flush, Low pitched mid-diastolic murmur (loudest at apex) loud s1 Snap due to thinkend valve cups.
