CVS Flashcards
What is acute limb ischemia
blockage of peripheral artery
Pathophy of acute limb ischemia
blockage reduced perfusion causing ischemia
5 RF of acute limb ischemia
- Smoking
- Diabetes mellitus
- Obesity
- Hypertension
- Hypercholesterolaemia
The 6p’s (acute limb ischemia signs and symptoms)
Pulseless
Paraesthesia
Pain
Paralysis
Pallor
Perishing cold
Investigations for acute limb ischemia
clinical diagnosis
You can roughly localise the blockage by locating thebifurcation distal to the last palpable pulse.
doppler to confirm absence of pulse
Mangement of acute limb ischemia
EMERGENCY
Thrombolytic agent
angioplasty
2 complications of acute limb ischemia
amputation
death
What is acute pericarditis
Inflammation of the pericardium
90% idiopathic or due to viral infections
Associated with systemic autoimmune disorders too
Acute vs chronic: 4-6 weeks vs >3 months
SS of acute pericarditis
Pleuritic central chest pain, worse on lying down, better sitting forward, intermittent fevers
Investigations for acute pericarditis
Examination: pericardial friction rub, tachycardia
ECG shows global upwardly concave ST-segment (J-point) elevations with PR segment depressions in most leads with J-point depression and PR elevation in leads aVR and V1
Mangement of acute pericarditis
Management: NSAIDs, can add colchicine.
- Corticosteroids
What is acute rheumatic fever
Rare but common in developing countries (major cause of death and heart disease)
Improvement in developed countries due to penicillin and improved social conditions and reduction in virulence of the GpA BHS
Autoimmune disease following a group A streptococcal infection.
Can affect joints, heart, brain, skin
Effects on heart can lead to permanent illness: chronic changes to heart valves referred to as chronic rheumatic disease
SS of acute rheumatic fever
Symptoms appear 1-5 weeks after sore throat
- Arthritis and toxicity with mild carditis (chest pain, SOB if severe), fever
- Palpitations, heart murmur, signs of heart failure
- Subcutaneous nodules/ erythema nodosum (swollen fat under skin causing red bumps and patches), chorea (jerky involuntary movements)
Investigation for acute rheumatic fever
Diagnosis based on Jones 2015 criteria
- Throat swabs, ESR, CRP, FBC. ECHO
Management for acute rhematic fever
Management: eradicate streptococcal infection, suppress inflammation, provide supportive treatment especially if complications such as HF
- Penicillin, aspirin, HF treatment if necessary cardiac surgery if treatment fails), diazepam if chorea present
what is angina
Pain/constricting discomfort in the chest
Radiating to the neck/shoulders/jaw/arms
Difference between stable and unstable angina presentation
Stable:
Occurs predictably
Lasting less than 15 mins, relieved by rest
with physical exertion or emotional stress
relieved within minutes of rest or GTN
unstable:
New onset or abrupt
often occurring at rest
lasts longer than 15 minutes
RF of angina
- smoking
- hyperlipidaemia
- age
- common in men but increases for women after menopause
- hypertension
- diabetes
- obesity
- exercise
- ethnicity
Pathophysiology of angina
Caused by an insufficient blood supply to myocardium
Atherosclerotic plaque inadequate oxygen to myocardium at times when oxygen demand increases (exercise)
SS of angina
chest pain
pain radiating to jaw neck and left arm
SOB
Dizziness
Investigation for angina
clinical history
Physical examination
blood test- rule out anaemia
ECG
Q-RISK
Management for angina (first line)
First line- Beta blocker or CCB, if both contraindicated or not tolerated then monotherapy with one of the following: nitrate, ivabradine, nicorandil, ranolazine
Management for angina (2 line)
Second line: if on B-blocker then add CCB. if on CCB then add b-blocker
Other management for angina
Aspirin
GTN
lifestyle advice
Primary prevention -> statins
secondary prevention-aspirin/clopidogrel, acei, statin, anti HTN
