Angina Flashcards
describe Stable angina
- pain while exercising and then the pain goes away when they stop exercising
what do you look for in a chest pain assessment
- how long have you had it
- how long doesn’t last
- where is it – localised generalised radiation
- what is it like
- what provokes and relives it
what are non cardiac chest pain problems
- digestive – heartburn, swallowing disorders
- neurogenic - cervical/thoracic spine, shingles
- pulmonary – pleurisy, pulmonary fibrosis
- bony pain – rib fracture, 2nd degree deposits
what are the causes of angina
- an imbalance between MI supply and demand
what can cause a decrease in myocardial oxygen supply
- coronary artery disease – atherosclerosis (usual cause), spasm, vasculitic disorders, post radiation therapy
- severe anaemia
what can cause a need for oxygen and thus an increase in myocardial oxygen demand
- left ventricular hypertrophy – hypertension, aortic stenosis, aortic regurgitation, hypertrophic cardiomyopathy
- right ventricular hypertrophy – pulmonary hypertension, pulmonary stenosis
- rapid tachyarrhythmias
what are the non invasive tests for angina
- functional testing for evidence of ischaemia – ETT, SPEC, Stress echo, Stress cMR
- anatomic testing for evidence of obstructive disease CTCA
what does the NICE guidelines say around the clinical assessment of angian
- Central chest discomfort lasting 5-15 minutes
- Provoked by exertion or emotional stress
- Relieved by rest or nitrate
- non anginal pain 1 or less than 1 - no diagnostic testing
- atypical angina 2 characteristics
- typical angina 3 characterics
- the last to are referred to diagnostic testing, CTCA
what drugs can increase oxygen delivery by increasing coronary flow thereby providing symptom relief
- Nitrates
• CaBs
• Nicorandil
• Revasc – bypass surgery or stenting
what drugs can reduce oxygen demand by decreasing heart rate thereby providing symptom relief
- BB
* ivabridine
what drugs can reduce oxygen demand by decreasing LV wall tension thereby providing symptom relief
BB • Nitrates • Nicorandil • CaBs • ranolazine
what drugs can reduce oxygen demand by decreasing contractility thereby providing symptom relief
- BB
* CaBs
what drugs can reduce oxygen demand by modifying energy metabolism thereby providing symptom relief
trimetazidine
what are the first line treatments
- beta blockers
- calcium channel blockers
what is given as 2nd degree prevention for angina
- aspirin → all patients
- statins → all patients - to target 4 and 2
- ACE-I → if other indications (HT/DM)
- P2Y12 receptor antagonist→ all patients after PCI or if intolerant of aspirin
