Cardiology Revision Phase2 Karl Wild and Rowena Speak The Peer Teaching Society is not liable for false or misleading information…
Stable Angina • Stable Angina - A retrosternal chest tightness or heaviness which is brought on by exertion and relieved by rest. • Symptoms – • constricting discomfort in the front of the chest, arms, neck and jaw, • Provoked by physical exertion, especially after meals and in cold, windy weather or excessive emotion • Relieved (within minutes) with rest or glyceryl trinitrite. • Causes – Mostly Atheroma. Anaemia, Aortic Stenosis, Tachyarrhythmia, Hypertrophic Cardiomyopathy Arteritis.
Unstable Angina – Angina of recent onset (<24hr) or a deterioration in stable angina with symptoms occurring at rest. Refractory Angina – Refers to patients with severe coronary artery disease in whom revascularization is not possible and whose angina is not controlled by medical therapy.
Angina Examination Signs – • Anaemia • Thyrotoxicosis • Hyperlipidaemia • Aortic Stenosis (Ejection Systolic murmur radiating to neck) • Check blood pressure
Angina Investigation • 12 lead ECG -During an attack – Transient ST depression & T wave inversion. • Cardiac Catheterization, CT Coronary Angiography • Exclude anaemia, diabetes, hyperlipidaemia, thyrotoxicosis and arteritis
Angina Management • Address risk factors • Aspirin 75mg daily • B-blocker/ Ca2+ – Atenolol/Amlodipine Both if uncontrolled on one • Nitrates – GTN, Isosorbide Mononitrate bd • Ivabradine/Nicorandil
Revascularisation • PCI – Single vessel CAD and normal LV function • CABG – Triple vessel disease and abnormal LV function
Acute Coronary Syndromes • ST Elevation Myocardial Infarction (STEMI) • Non ST Elevation Myocardial Infarction (NSTEMI) • Unstable Angina • Causes – Plaque rupture Coronary Spasm Thrombosis Vasculitis Emboli
NSTEMI ECG changes - • ST depression • T Wave inversion • Could be normal
STEMI • ECG changes – Tall T waves ST elevation New LBBB Later – T wave inversion Pathological Q waves
ACS symptoms - • Acute central chest pain • Radiates neck and arm • Lasting >20 minutes • Nausea • Dyspnoea • Palpitations
ACS Signs - • Distress, anxiety, pallor, sweatiness • Tachy/bradycardia • Hyper/hypotension • 4th heart sound • Signs of HF and murmur • Later - Pericardial friction rub & peripheral oedema
ACS Investigations • ECG • Bloods • Cardiac Enzymes – Cardiac Troponin (T & I) ^ 3 hours after onset and peak at 24-48hr Creatine Kinase (CK-MB) ^ 3 hours after onset, peak within 24hr
ACS Management NSTEMI Oxygen Morphine GTN Aspirin 300mg PO Clopidogrel 300mg PO Atenolol PO / Verapamil PO Enoxaparin More Nitrate if in pain. High risk – GPIIb/Iia antagonist (tirofiban) Low risk – Discharge if 12hr Trop -ve STEMI Oxygen Aspirin 300mg PO Morphine GTN PRIMARY PCI / Thrombolysis Atenolol

Hypertension (HTN) • Essential (primary) HTN = idiopathic • SecondaryHTN= something is causing it The Peer Teaching Society is not liable for false or misleading information…
HTN: causes of secondary • Renal disease: intrinsic, renovascular • Endocrine: Cushing’s, Conn’s, Phaeochromocytoma, Acromegaly, Hyperparathyroidism • Coarctation of the aorta • Pre-eclampsia and HTN in pregnancy • Drugs and toxins: alcohol, cocaine, ciclosporin, decongestants, adrenergic medications, oral contraceptives, corticosteroids, liquorice The Peer Teaching Society is not liable for false or misleading information…
HTN: symptoms • Usually asymptomatic • Headaches, paroxysmal sweats or palpitations = think phaeochromocytoma (tumour of the adrenal medulla) The Peer Teaching Society is not liable for false or misleading information…
HTN: diagnosis • GP surgery BP measurements of adults at least every 5 years White coat syndrome = patients have elevated BP in a clinical setting but not in other settings due to anxiety experienced during a clinic visit. • ABPM = ambulatory blood pressure monitoring • HBPM = home blood pressure monitoring • Cardiovascular risk assessment • HTN retinopathy screening • ECG to look for LVH • Bloods: electrolytes, creatinine, eGFR, fasting glucose, lipids • Urinalysis: albuminuria, proteinuria or haematuria ± albumin:creatinine ratio. The Peer Teaching Society is not liable for false or misleading information…
HTN: stages • Stage 1 - BP in surgery/clinic is ≥140/90 mm Hg and ABPM or HBPM is ≥135/85 mm Hg. • Stage 2 - BP in surgery/clinic is ≥160/100 mm Hg and ABPM or HBPM is ≥150/95 mm Hg. • Severe - BP in surgery/clinic is ≥180/110 mm Hg or higher. The Peer Teaching Society is not liable for false or misleading information…
HTN: lifestyle interventions • Lower salt intake • Reduce alcohol consumption • Stop smoking • Do more exercise • Be less stressed The Peer Teaching Society is not liable for false or misleading information…
HTN: initiation of treatment • Offer step 1 treatment to people aged under 80 with stage 1 hypertension and one or more of: • target organ damage • established cardiovascular disease • renal disease • diabetes • 10-year cardiovascular risk equivalent to 20% • Offer step 1 treatment to people of any age with stage 2 hypertension The Peer Teaching Society is not liable for false or misleading information…

HF Investigations • Chest X ray • Bloods • B-type Natriuretic Peptide • ECG • Transthoracic echocardiogram
Chronic HF Management • Diuretics – Furosemide • ACE-I – Ramipril / ARB – Candesartan • B-Blocker – Atenolol • Spironolactone • Digoxin • Vasodilators – Hydralazine & Isosorbide Dinitrate
Acute HF Management • Oxygen • Diamorphine IV • Furosemide IV • GTN spray • If systolic BP >100mmHg IV nitrate
HF Question A 75 year-old woman is brought to the Emergency Department by ambulance following an emergency call at 4 am. She is pain-free but very breathless. She has previously been diagnosed with congestive cardiac failure and is receiving drug treatment from her General Practitioner.
