TRATAMIENTO ANTITROMBÓTICO en SCASEST
Before angiography it may not be clear what the true diagnosis is
• The ACCOAST-PCI study shows that there is no downside in
waiting to provide prasugrel until after coronary angiography in
patients who will need dual antiplatelet therapy for stenting1. 32%
of patients in ACCOAST did not go to PCI (but CABG or MM) →
not in-label for prasugrel)2

Why is it important to confirm the diagnosis NSTE-ACS before initiating any DAPT?
• Myocarditis• Takatsubo• Arrhythmias• Acute heart failure• Aortic dissection• Pulmonary embolism• Chemotherapy
• Infection/Sepsis• Circulatory shock• COPD exacerbation• Pneumonia• CO intoxication• …….• …….
There are many other causes of myocardial injury with/without CAD
Pretreatment not beneficial or even harmful
NSTE-ACS patient receiving DES: What do the trials show?
• BASKET-PROVE trial1: Compared with BMS, use of DES in NSTE-ACS patients undergoing stent implantation in large vessels was associated with a reduction in both TVR and the combined endpoint consisting of cardiovascular death/MI. Thus, DES use improves both efficacy and safety. These findings support the use of DES in NSTE-ACS patients.
• Prasugrel: TRITON-NSTE DES subgroup: Statistical significant 65% RRR in definite stent thrombosis vs. clopidogrel (p=0.0001)2,3
• Ticagrelor: PLATO-NSTE DES subgroup: Non-significant 31% RRR in definite stent thrombosis vs. clopidogrel (p=0.2304)4,5

1. Identificación de los criterios primarios o secundarios de riesgo elevado para la indicación de una estrategia invasiva precoz < 24 horas: aumento de la troponina; cambios dinámicos del segmento ST o la onda T (sintomáticos o silenciosos) .
• Orientación a la UCI• Traslado al laboratorio de cateterismo para coronariografía ± angioplastia
en las 24 horas.
2. SCASEST es una urgencia médica.
3. La realización de anamnesis, exploración y ECG permite el diagnóstico inicial.
4. La estratificación del riesgo es indispensable para decidir la estrategia a seguir.
5. En SCASEST de alto riesgo se recomienda la realización de cateterismo en las primeras 24 horas.
6. Es más inconveniente seguir el camino de enviar al paciente a UCI y después cateterismo a las 24 horas.
