IHD Flashcards
What 3 things on ECG would indicate thrombolysis is appropriate?
ST elevation (2 consecutive leads, 1mm or 2mm in anterior)
Posterior MI
new bundle branch block
What are some contraindicators for thrombolysis?
stroke (any haemorrhagic, ischaemic in the last 3 months)
structural cerebral vascular lesion
malignant intracranial neoplasm
suspected aortic dissection
active internal bleeding
recent trauma, surgery or acute cerebrovascular event
What are 4 types of thrombolysis drug?
alteplase, reteplase, streptokinase, tenecteplase
What are some SE of thrombolysis?
bleeding (stroke), migration of blood clots, kidney damage if patient has kidney disease, hypotension, arrhythmias, streptokinase has antibodies which stop it working again
Which treatment for MI is preferred?
PCI
What are some RF for IHD?
age, sex, lack of exercise, high blood glucose, high cholesterol, stress, high BP, S. Asian, alcohol, autoimmune diseases, smoking, family history
What are some differentials of acute coronary syndrome?
stable angina, PE, GORD, costrochondritis, anxiety, pericarditis, cardiac tamponade, shingles, pneumothorax, esophageal spasm, pancreatitis
What are the blood tests to detect cardiac damage?
Troponin (T or I) -more specific
Creatine kinase or CK-MB
Which leads on ECG are which areas?
Anterior/Septal - V1-V4
Lateral - I, aVL, V5-V6
Inferior - II, III, aVF
How quickly does PCI need to be done?
90 mins of arrival at hospital - over 12 hours is unhelpful
How quickly do you need to do thrombolysis?
Within 30 mins ideally - definetly 4 hours
