  • Why are vasodilators used in angina?
    Increase blood flow
  • Why are beta blockers used in angina?
    Reduce HR & BP
    Reduce myocardial O2 consumption
    Increase time in diastole (more coronary artery filling)
  • What are Ca+2 channel blockers used in angina?
    Inhibit Ca+2 channel in myocardium, cardiac conductive tissue & vascular smooth muscle
  • What is PCI?
    Percutaneous Coronary Intervention
    Process of dilating coronary artery stenosis -> introduce inflatable balloon & metallic stent
  • What are the complications of PCI?
    Bleeding
    Haematoma
    Dissection
    Pseudo-aneurysm from arterial puncture site
    Acute MI
    Stroke
    Death
  • What is CABG?
    Coronary Artery Bypass Grafting
    Autologous veins ar arteries are anastomosed to the ascending aorta & to native coronary arteries distal to area of stenosis
  • What is the initial management of MI?
    Give aspirin = prevent clots
    Cardiac ischaemia pain = IV morphine
    O2
    Primary PCI = insert stent to restore blood flow
    Dual anti-platelet therapy = aspirin with clopidogrel
  • What is the procedure of an angioplasty?
    Use local anaesthetic
    Thin, flexible tube inserted into an artery in groin, wrist or arm & guided to affected coronary artery by X-ray video
    When catheter is in place, a thin wire is guided down the length of the coronary artery to deliver a small balloon to affected section
    Balloon inflated to widen artery -> squashes fatty deposits against wall
    Stent expands & stays in place after balloon is deflated and removed
  • What are the contraindications of statins?
    Pregnancy
    Breast feeding
    Active hepatic disease
  • Why do you not use vasodilators, like dipyridamole, in angina?
    Coronary steal -> even less blood flow through ischaemic area as collateral vessels are not dilated
  • What is an angioplasty?
    Procedure used to widen blocked/narrowed coronary arteries
  • What is one of the major side effects of statins?
    Rhabdomyolysis -> can lead to myoglobin release (tea coloured urine)
  • Why is chewable aspirin given in MI?
    Faster absorption
