This document provides an overview of cardiology topics including basic physiology, common investigations, conditions like hypertension, angina, heart failure, and procedures. It discusses evaluation of patients presenting with chest pain or shortness of breath and management of acute coronary syndromes, arrhythmias, valve diseases and more. Investigations covered include ECG, echocardiogram, stress testing and scores for predicting patient risk. Treatment focuses on lifestyle changes, medications, procedures like angiography or ablation.

9. Hypertension
A 62-year old male attends your GP surgery with concerns about his blood pressure. His father suffered from
heart disease and died at 70-years old from a heart attack. He tries to keep as active as possible taking 30-
minute walks every day, but does admit to drinking 3 pints of strong beer a day and smoking 5 cigarettes a day
for the past 30 years. He accepts his diet probably isn’t the healthiest eating a full English every day for breakfast
and snacking regularly throughout the day on chocolate biscuits and crisps, but he feels he needs the energy
otherwise he won’t be able to manage his farm. On examination his blood pressure is 152/95.

10. A 47-year old female presents to A&E complaining of chest pain. It started two hours
ago when she was out on a jog. It felt like a tight band around her chest and she
became short of breath. An ambulance quickly arrived and gave her 300mg aspirin
as well as a spray underneath her tongue. The pain quickly subsided and she now
feels well at rest.

5.If neither is tolerated use a long-acting nitrate, ivabradine,
nicorandil or ranolazine
11. Angina
A 60-year old man with stable angina presents for a routine review. He reports he is
still symptomatic despite treatment with verapamil. The pain is starting to come on
with minimal activity and his functioning is severely impeded. He has a spray which
does still help with the symptoms.
12. A 56-year old male presents with sharp crushing chest pain that radiates down his
left arm. He appears to be cold and clammy and short for breath, although his O2
saturations are stable at 98%. He is tachycardic and hypertensive and reports having
a previous diagnosis of Angina. He has been given aspirin and GTN spray but this has
not alleviated the symptoms.

16. Atrial Fibrillation
A 72-year old female presents complaining of feeling regularly short of breath and
feeling dizzy. She reports that she hasn’t lost consciousness at anytime and that the
episodes last only 5 minutes at a time. They are very distressing and she is worried
she is going to die when the attack comes on.

21. A 45-year old male with a BMI of 56 attended his GP surgery today for a nurses
appointment. He regularly drinks 12 units a day and smokes 15 cigarettes per day.
His diet is high in red meat and his father died of a myocardial infarction at the age
of 53. The nurse is alarmed by the appearance of his ECG as shown below.

26. Heart Failure
A 72-year old male with established Atrial Fibrillation presents to the Emergency
Department with increasing shortness of breath. He finds he is unable to perform
strenuous activities anymore and can struggle with housework on occasion. He does
not have any chest pain but has noticed ankle swelling and needs to be propped up
on 4 pillows at night when he sleeps. His GP has seen him previously and started him
on Simvastatin, Bisoprolol and Ramipril.
28. Heart Failure

I
Cardiac disease, but no symptoms and no
limitation in ordinary physical activity,
e.g. shortness of breath when walking,
climbing stairs etc.
II
Mild symptoms (mild shortness of breath
and/or angina) and slight limitation
during ordinary activity.

31. Deep Vein Thrombosis
A 26-year old female presents to her GP with a tender, swollen calf. It came on quite
over the previous 3 days. She has recently gotten back from Australia and had a fall
from 6ft whilst away. The doctors there reassured her that she was fine and told her
to enjoy her holiday. She has been on the combined oral contraceptive pill for 10
years.

36. Pulmonary Embolism
Two months later the same 26-year old collapses suddenly in the supermarket. An
ambulance is called and she bought into A&E. She is extremely short of breath and
has right sided chest pain on inspiration. The ambulance crew report she had been
coughing up some blood. Her temperature is 37.4°, pulse rate is 102, respiratory rate
is 34 and O2 saturations are 86%.
37. Background Information
• Lung tissue ventilated but not perfused
• Alveolar collapse
• Reduction in cross-sectional area of pulmonary arterial bed
• Elevation of pulmonary arterial pressure
• Reduction in cardiac output
• Lung tissue may infarct
• Large/multiple emboli can abruptly increase arterial pressure to an
afterload level that can’t be matched by the right ventricle
• Sudden death may occur due to acute right ventricular failure
38. • Annual incidence of 3-4 per 100 000 in the UK
• Untreated risk of death is 87%
• Treated this falls to 2.3%
• Can lead to CHRONIC THOMBOEMBOLIC PULMONARY

Editor's Notes
Holter Monitor = 24 hour ECG tape
Cardiac stress test = ECG + blood pressure monitoring on treadmill. Can be combined with echocardiography or nuclear imaging (thalidomide) to assess blood flow to the heart.
CT coronary calcium – identifies extent of calcified plaque in coronary arteries. Use in patients with 10-29% risk of having Coronary Artery Disease
TIMI identifies % risk at 14 days of all-cause mortality, new/recurrent MI or severe recurrent ischaemia
GRACE scoring identifies probability of Death or Death/MI in hospital or at 6 months.
CHAD2S2Vasc is probability of a patient with AF having a stroke within a year.
Framingham Risk Score estimates the 10-year cardiovascular risk
Wells Clinical Score indicates likelihood of DVT or PE at that time
Classify hypertension into stages. Stage 1 = Clinic BP >= 140/90 and subsequent ABPM average 135/85. Stage 2 = +10 for clinic BP and +15 for ABPM. Severe = clinc systolic >=180 or diastolic >= 110.
FIRST STEP = offer ambulatory/home blood pressure monitoring.
LIFESTYLE INTERVENTIONS:- diet & exercise, alcohol, caffeine, salt intake, smoking, local initiatives, relaxation therapies
Diuretic – use chlorthalidone or indapamide.
STEP 4:- DIURETIC TREATMENT FIRST:- if K+ <4.5 use spironolactone 25mg OD. If K+>4.5 add higher dose thiazide. If not tolerated, contraindicated or ineffective add alpha or beta blocker.
FIRST – ABC approach and rule out acute coronary syndrome (troponin and ECG)
Risk of CAD – age, sex and type of angina.
Rule out other causes of chest pain
Verapamil CAN’T be given with a beta blocker. Risk of heart failure. Diltiazem used with caution (risk of AV block) Must give amlodipine/felodipine.
Isosorbide mononitrate.
Low risk = initial conservative management
Low risk (>1.5-3.0%) = 300mg clopidorel and continue for 12 months) THEN if recurrent ischaemia coronary angiography
Intermediate and above = 300mg clopidogrel and continue for 12 months. Add a glycoprotein inhibitor (tirofiban or eptifabatide). Bvalirudin as an alternative to combination heparin therapy. Coronary angiography (with PCI if indicated) within 96 hours. Discuss with cardiologist then do either CABG or PCI or conservative if indicated.
Dressler’s syndrome:- occurs 2-6 weeks post MI. Autoimmune reaction against antigenic proteins. Fever, pleuritic pain, pericardial effusion and raised ESR. Treated with NSAIDs.
Aneurysm = persistent ST elevation and left ventricular failure
Free wall rupture:- seen 1-2 weeks afterwards present with acte heart failure and cardiac tamponade.
VSD = acute heart failure with pan systolic murmur.
Rate control = beta-blockers, calcium channel blockers, digoxin
Rhythm control = amiodarone if structural heart disease, fleicanide if no structural heart disease
Anticoagulation & cardioversion: if onset >48 hours anticoagulate 3 weeks prior to cardioversion and 4 weeks after.
No specific treatment for RBBB
LBBB may be caused my ischaemia or aortic stenosis. Treat underlying cause.
Due to accessory pathway – bundle of kent
Treatment = cardioversion. Electrical if haemodynamically unstable. Pharmacological if stable. Radiofrequency catheter ablation.
Smoking, alcohol, sexual activity, flying, driving
Yearly influenza vaccines & one-off pneumococcal vaccine
Ivabradine used ONLY in NYHA II-IV, HR >75, with LV ejection fraction <35%. MUST have been stable on aldosterone antagonist, ACEi & beta-blockers
DRUG Treatment = diuretics (frusemide), amlodipine, anticoagulants (for sinus rhythym with history of thromboembolism, left ventricular aneurysm, intracardiac thrombus), aspirin 75-150mg daily, POSITIVE inotropic agents (dobutamine/milrinone), amiodarone (ONLY AFTER SPECIALIST CONSULTATION)
Other interventions = implantable defibrillator, valve replacements
Monitoring = Medication reviews, cardiac function reviews, monitor U&Es, serum creatinine, & eGFR. Consider monitoring BNP in hospital or if drug treatment is difficult. Serum digoxin 8-12 hours post-last dose if toxicity suspected.
Refer for same-day assessment if pregnant/in the puerperium/IV drug user/no d-dimer test availableIf LIKELY to have DVT (Wells Score of 2 or more) refer for same-day assessment/management
If UNLIKELY to have DVT take blood sample for D-dimer testing
Admission criteria = patient at enhanced risk of bleeding, IV drug abuser, dementia, PE, bilateral DVT, pregnant
Engage in regular walking exercise, elevate leg when sitting, extended travel should be delayed for 2 weeks after starting treatment
CTEPH occurs in 0.5-5% of people. Emboli replaced over months or years by fibrous tissue
Well Score = <2: low risk (3.4%). 2-6: moderate risk (27.8%). >6 points: high risk (78.4%)
*Unless d-dimer test result could be available immediately
D-dimer testing, CXR & ECG to exclude alternatives, ABG, CTPA, VQ scan, lower limb compression venous ultrasoundECHOCARDIOGRAPHY IF HYPOTENSIVE, absence of RHF excludes PE
Relatively common – 5% of all A&E admissions are pericarditis.
Diffuse st segment elevation “saddle changes”
PR depression
Two types of recurring: incessant = once NSAIDs withdrawn symptoms return. Intermittent = long gaps between symptoms
Staph aureus – 30% of IE associated with prosthetic valves. Most common cause overall. HIGH MORTALITY.
Streptococci:-
Viridans = 50-60% of subacute IE cases
Group D strep = subacute and 3rd most common cause
Intermedius = 15% of all cases of IE
A,C & G strep = high mortality
Group B strep = acute disease, high mortality. Occurs in pregnancy and elderly.
Blood cultures = consistent with infective endocarditis e.g. STREP VIRIDANS and the HACEK group. Persistent staphu aureus/epidemidis bacteraemia. Positive serology for coxielle burnetti, bartonella or chlamydia psittaci. Positive molecular assays for gene targets
Evidence of endocardial involvement = positive echocardiogram or new valvular regurgitations.
MANAGEMENT = ADMIT. Empirical therapy = amoxicillin and gentamicin/vancomycin and gentamicin and rifampicin (if prostetic valve/penicillin allergic)
Staph = flucloxacillinStreptococci = benzylpenicillin
Prosthetic valve = benzylpenicillin + gentimicin
ALWAYS FOLLOW LOCAL GUIDELINES
