Coronary Heart Disease death/100,000

Physicians have several goals when treating a patient with ACS:  To relieve ischemia and associated discomfort  To restore blood flow and prevent complete vessel occlusion in patients with NSTE-ACS, and preventing infarction expansion in both patients with STEMI or NSTE-ACS  To prevent complications or death ACS Acute Treatment Goals

To achieve these goals, the single most important step to do is:  Vital signs monitoring  Cardiac biomarkers test  GRACE / TIMI risk assessment  Asses previous cardiac history

NSTE-ACS Reperfusion Treatment Strategies

Risk Assessment 7 Risk assessment is used to help physicians determine whether to pursue an initially conservative strategy or an invasive strategy:

TIMI Risk Score 8 The TIMI risk score is a clinical characteristics used at presentation to estimate the early risk for patients hospitalized with ACS and can be factored into a physician’s decision regarding whether to pursue an: Initial conservative strategy or Invasive strategy for patients with NSTE-ACS

GRACE Risk Score Components 9 The higher the total points, the greater the risk. Like TIMI risk scoring, GRACE risk scores can be useful to clinicians in guiding treatment type and intensity.

GRACE & TIMI Risk Score

NSTE-ACS Selection of Acute Treatment Strategy Is a critical strategic decision required whether to move with an invasive or an initially conservative treatment strategy. The invasive strategy involves diagnostic angiography and possible revascularization by PCI when determine is needed. 11

Initial Conservative Strategy NSTE-ACS Factors that can prompt a physician to choose an initially conservative treatment strategy: 12

STEMI Factors Influencing The Choice of Reperfusion Treatment Strategy The choice of reperfusion strategy is strongly influenced by the local EMS i.e. : Whether the patient is transported to a PCI-capable vs. Non-PCI-capable hospital

STEMI Contraindications for Fibrinolysis  Hemorrhage is the most important risk of fibrinolytic therapy  Certain patients with bleeding risks are contraindicated for fibrinolysis 20

PCI After Fibrinolysis 21 PCI after fibrinolysis is indicated when: There is objective evidence of recurrent MI Moderate or severe spontaneous or provocable myocardial ischemia during recovery from STEMI Persistent evidence of ongoing ischemia Cardiogenic shock or hemodynamic instability
