STEMI: Prehospital

ESC guidelines 2012:

• Evidence that properly trained paramedical personnel can effectively identify

AMI and provide timely reperfusion

• Paramedics trained to administer thrombolytics do so safely and effectively

• Since pre-hospital thrombolysis is an attractive therapeutic option in patients

presenting early after symptom onset, especially when transfer time is

prolonged, ongoing training of paramedics to undertake these functions is

recommended, even in the era of primary PCI

Stroke: Endovascular thrombectomy

Metaanalysis: Goyal et al., Lancet 2016:

“Endovascular thrombectomy is of benefit to most patients with

acute ischaemic stroke caused by occlusion of the proximal anterior

circulation, irrespective of patient characteristics or geographical location.

Global implications on structuring systems of care to provide timely

treatment to patients with acute ischaemic stroke due to large vessel

occlusion”

Stroke: Endovascular thrombectomy

2015 AHA/ASA Focused Update of the 2013 Guidelines:

Patients eligible for intravenous r-tPA should receive intravenous r-tPA even if

endovascular treatments are being considered (Class I; Level of Evidence A)

(unchanged from the 2013 guideline)

Patients should receive endovascular therapy with a stent retriever if they meet all the

following criteria (Class I; Level of Evidence A). (New recommendation):

(a) prestroke mRS score 0 to 1,

(b) acute ischemic stroke receiving intravenous r-tPA within 4.5 hours of onset

according to guidelines from professional medical societies,

(c) causative occlusion of the internal carotid artery or proximal MCA (M1),

(d) age ≥18 years,

(e) NIHSS score of ≥6,

(f) ASPECTS of ≥6, and

(g) treatment can be initiated (groin puncture) within 6 hours of symptom onset

Normotensive patients with intermediate-risk pulmonary embolism:

composite primary outcome of early death or hemodynamic decompensation

was reduced after treatment with a single intravenous bolus of tenecteplase.

Tenecteplase was associated with a significant increase in the

risk of intracranial and other major bleeding.

Great caution is warranted when considering

fibrinolytic therapy for hemodynamically stable patients with pulmonary

embolism, right ventricular dysfunction, and positive cardiac troponin

Strategies to minimize bleeding risk

• Contraindications

• Dosing consideration

• Administration technique

• Reperfusion strategy:

• Systemic fibrinolysis

• Catheter-based reperfusion therapy (EKOS)

• Cave: ECMO after EKOS
