By the end of this session, it is expected that the students will be able to:

img-1.jpeg

  • ☐ Diagnose different types of ACS
  • ☐ Outline the steps in the management of different types of ACS
  • ☐ Interpret and manage different ACS clinical scenarios

ESSENCE

img-2.jpeg

CAD is the third leading cause of mortality worldwide and is associated with 17.8 million deaths annually.

img-3.jpeg

Delay in seeking medical attention is common, and more often reported in:

  • Women
  • Older adults
  • Patients with high chronic disease burden

img-4.jpeg

The management of ACS has evolved over recent years, with the development of new drugs and procedures such as percutaneous coronary intervention (PCI).

STEMI: Early Management (NICE Guidelines)

NICE β€” National Institute for Health and Care Excellence

Immediate Actions

  1. Offer a 300-mg loading dose of aspirin as soon as possible and continue aspirin indefinitely unless contraindicated
  2. Do NOT offer routine GPIs or fibrinolytic drugs before arrival at the catheter laboratory if primary PCI planned
  3. Immediately assess eligibility (irrespective of age, ethnicity, sex or level of consciousness) for reperfusion therapy
  4. If eligible, offer reperfusion therapy as soon as possible. Otherwise offer medical management

Medical Management

  • Offer ticagrelor with aspirin unless high bleeding risk
  • Consider clopidogrel with aspirin, or aspirin alone, for high bleeding risk

Cardiology Assessment

  • Offer cardiology assessment
  • Assess left ventricular function

Reperfusion Therapy (Primary PCI or Fibrinolysis)

Angiography with Follow-on Primary PCI

  • Offer if:
    • Presenting within 12 hours of symptoms AND PCI can be delivered in 120 mins
  • Consider if:
    • Presenting more than 12 hours after symptoms AND continuing myocardial ischaemia or cardiogenic shock
  • Consider radial in preference to femoral access

Drug Therapy for Primary PCI

  • Offer prasugrel* with aspirin if NOT already taking oral anticoagulant
  • Offer clopidogrel with aspirin if taking an oral anticoagulant
  • Offer unfractionated heparin with bailout GPI for radial access
  • Consider bivalirudin with bailout GPI if femoral access needed

* For people aged 75 and over, think about whether risk of bleeding with prasugrel outweighs its effectiveness; if so offer ticagrelor or clopidogrel as alternatives

Stenting and Revascularisation

  • If stenting indicated, offer a drug-eluting stent
  • Offer complete revascularisation (consider doing this in the index admission) if:
    • Multivessel coronary artery disease
    • No cardiogenic shock
  • Consider culprit only during the index procedure for cardiogenic shock

Fibrinolysis

  • Offer if:
    • Presenting within 12 hours of symptoms
    • PCI not possible in 120 mins
  • Give an antithrombin at the same time
  • Offer ECG 60-90 mins after fibrinolysis
  • Offer ticagrelor with aspirin unless high bleeding risk
  • Consider clopidogrel with aspirin, or aspirin alone, for high bleeding risk
  • Do NOT repeat fibrinolysis; offer immediate angiography with follow-on PCI if indicated by ECG
  • Seek specialist advice for recurrent myocardial ischaemia and offer angiography with follow-on PCI if appropriate
  • Consider angiography during same admission if stable after successful fibrinolysis
  • Assess left ventricular function

Cardiac Rehabilitation and Secondary Prevention

Flowchart Overview

STEMI identified

↓

Aspirin 300mg

↓

Can PCI be done within 120 mins?

  • YES β†’ Proceed to PCI
  • NO β†’ Proceed to Fibrinolysis

PCI Pathway

  • Give prasugrel
  • Radial access is preferred
  • Give unfractionated heparin + bailout glycoprotein IIb/IIIa inhibitor
  • Drug-eluting stents should be used in preference

Fibrinolysis Pathway

  • Give an antithrombin at the same time
  • Following procedure give ticagrelor
  • For ongoing myocardial ischaemia consider PCI

Assumptions

  • Patient presents within 12 hours of symptom onset
  • If patient presents after 12 hours consider PCI if ongoing myocardial ischaemia or cardiogenic shock
  • Patient is NOT a high bleeding risk
    • If high bleeding risk: consider swapping prasugrel for ticagrelor / swapping ticagrelor for clopidogrel
  • Patient is NOT on oral anticoagulants
    • If on oral anticoagulants: swap prasugrel for clopidogrel

STEMI PCI: Detailed Steps

StepAction

Step 2Aspirin 300mg
Step 3PCI

Prior PCI (Dual Antiplatelet Therapy)

Patient StatusAntiplatelet Regimen
NOT on oral anticoagulantAspirin + prasugrel
ON oral anticoagulantAspirin + clopidogrel

Drug Therapy During PCI

Access RouteAnticoagulant Strategy
Radial accessβ€’ Unfractionated heparin with bailout glycoprotein IIb/IIIa inhibitor (GPI)
Femoral accessβ€’ Bivalirudin with bailout GPI

Other Procedures

  • Thrombus aspiration β€” Not mechanical extraction
  • Drug-eluting stents

What is PCI?

img-53.jpeg

PCI Timeframe

img-54.jpeg

  • A primary PCI strategy is recommended over fibrinolysis; if the presentation is within 12 hrs of onset of symptoms AND PCI can be delivered within 120 mins
  • Consider PCI if fail fibrinolysis evident by ECG at 90 minutes showing non-resolution of the ST elevation
  • If patients present after 12 hrs and evidence of ongoing ischaemia β†’ rescue PCI
  • Radial access is preferred to femoral access

PCI Complications

img-55.jpeg

Periprocedural Complications

  • Minor bleeding/haematoma
  • Retroperitoneal haematoma
  • Cholesterol embolization
    • oligouria – short down at kidney – perforic rash
  • Cardiac tamponade

Longer Term Complications

  • Restenosis β€” first 3-6 months (5-20%)
  • Stent thrombosis β€” First month (1-2%)

Fibrinolysis (When PCI Not Available)

If patient NOT for PCI

  • If primary PCI cannot be delivered within 120 mins
  • Thrombolytic drugs activate plasminogen to form plasmin β€œActilyse”
  • Tissue plasminogen activator (tPA) shown clear mortality benefits over streptokinase

Disadvantages:

  • Hypotension
  • Allergic reaction

Dosing:

  • 100 mg total dose infused over 1.5 hr
  • 15 mg IVP bolus over 1-2 minutes, remaining as an IV infusion

Prior SurgeryIntracranial or intraspinal (2 months), Head trauma (3 months)
Intracranial ConditionsIschemic stroke (3 months), AV malformation, Malignancy
OthersSuspected Aortic dissection, Unresponsive severe hypertension, Previous use of streptokinase (6 months)

Antithrombotic Treatments

img-61.jpeg

img-62.jpeg

Antithrombotic treatments include:

  • Anticoagulant drugs
  • Antiplatelet drugs

img-63.jpeg


Drugs Used for Management of ACS

Drug NameMechanism of Action (MOA)
HeparinActivates anti-thrombin III
Clopidogrel, Ticagrelor, PrasugrelP2Y12 inhibitor
AbciximabGlycoprotein IIb/IIIa inhibitor
DabigatranDirect thrombin inhibitor
RivaroxabanDirect factor X inhibitor
FondaparinuxActivates antithrombin III, which in turn potentiates the inhibition of coagulation factors Xa
BivalirudinReversible direct thrombin inhibitor

Dual Antiplatelet Treatment (DAPT)

Drug Selection Guide

  • Ticagrelor β†’ In anti-thrombolytic therapy
  • Prasugrel β†’ PCI
    • If bleeding tendency: β€œgive Ticagrelor”
    • If patient on anticoagulant: β€œgive Clopidogrel”

Rationale for DAPT

  • Aspirin and ADP inhibitors work by blocking different platelet aggregation pathways (potential synergy)
  • Clopidogrel: ADP inhibitor; due to its interindividual variability in antiplatelet effects, newer agents (prasugrel and ticagrelor) were developed

NICE Guidelines Recommendations

  • Marked reduction in short- and long-term ischaemic events when using prasugrel and aspirin, compared to clopidogrel and aspirin in moderate- to high-risk ACS patients
  • Starting DAPT with Aspirin and Ticagrelor for 12 months, as a secondary prevention strategy

NSTEMI/Unstable Angina: Simplified Management

img-64.jpeg

Conservative Management

  • Give ticagrelor
  • Bleeding tendency β†’ clopidogrel

PCI for NSTEMI

  • Offer immediately if clinically unstable
  • Otherwise offer within 72 hours
  • Give prasugrel or ticagrelor
  • Give unfractionated heparin
  • Drug-eluting stents should be used in preference

Assumptions

  • Patient is NOT a high bleeding risk
    • If high bleeding risk consider:
      • Swapping fondaparinux for an alternative antithrombin/dose
      • Swapping prasugrel for ticagrelor / swapping ticagrelor for clopidogrel
  • Patient is NOT on oral anticoagulants
    • If on oral anticoagulants: swap prasugrel/ticagrelor for clopidogrel
