  • EL PRIMER PASO AL MANEJO DE SHOCK CARDIOGENO ES SU PREVENCIÓN MEDIANTE LA LIMITACIÓN DEL TAMAÑO DEL IMA, RESTABLECER LA PERFUSIÓN CORONARIA Y CONTROLANDO LAS RESPUESTAS INJURIOSAS
  • La perfusión coronaria ocurre el momento de máximo volumen de VI y de mínima resistencia del mismo. Las 2 Presiones coronarias y --- generan perfusión contra la baja resistencia Diastólica En sistole las presiones de A– y VI se igualan el VI se contrae no hay perfusión + volumen VI. Si la presión coronaria cae bajo la Presión aórtica, el flujo se mantiene por auto refulación. ------ Luego ISQUEMIA = ------ CONTRACTILIDAD PFVI Bajo Gas—o SHOCK P P ISQUEMIA
  • The emergency management of patients with cardiogenic shock (CS), acute pulmonary edema (PE) or both is outlined. Las complicaciones que demandan emergencias ee el IMA mas comunmente son Edema Pulmonar Agudo, Hipovolemia, Shoc Cadiógeno y Arritmias: Si la PAS está 70 a 100 mm Hg, Pero sin Sx ni Sg de ShocK: Dobutamina 2 a 20 mcg/kg/min IV. Si la PAS esta <70 a 100 mm Hg con Sx y Sx de Shock: Dopamine 5 a 18 mcg/Kg/min IV Si la PAS esta <70 mm Hg: Norepinefrina 5 a 30 mcg/Kg/min IV. Si la PAS >100mm Hg: NTG. Si la PAS >100 mmHg ( y hasta 30 mmhg de la PA basal): Inhibidores e la ECA. El siguiente paso medidas DX y RX
  • Desde e Etudio SOLVD con el Enalapril se ha prbado que los inhibidores de la ECA mejoran mortalidad en presencia de bajo gasto o ICC. Lo confirman el SAVE, el AIRE, el TRACE.
  • Seguimos el mismo abordaje Probabilístico de 4 CLASES de INDICACIONES de lo Beneficioso a lo Perjudicial con 3 niveles de Evidencia.
  • Pacientes e Shock Cardíogenico de Presentación Temprana o TARDIA ------ IABP ---- ANYLA ---- REN---LIZA Ahora, en la Presentación Temprana ----- FIBRINOLISIS, si es que >90¨ ( sin APC ) < 3 HORAS del IMA 1 – 2 Vasos 3 vasos Modea--- 3 vasos o tienen A P C ARI Otros Vasos
  • This algorithm shows the treatment paths for patients who initially undergo a primary invasive strategy, receive fibrinolytic therapy, or do not undergo reperfusion therapy for STEMI. Patients who have not undergone a primary invasive strategy and have no high risk features should undergo functional evaluation using one of the noninvasive tests shown. When clinically significant ischemia is detected, patients should undergo catheterization and revascularization as indicated; if no clinically significant ischemia is detected, medical therapy is prescribed post-STEMI.
  • Algorithm to aid in selection of implantable cardioverter/defibrillator (ICD) in patients with STEMI and diminished ejection fraction (EF). The appropriate management path is selected based upon left ventricular ejection fraction (LVEF) measured at least one month after STEMI. These criteria, that are based on the published data, form the basis for the full-text guidelines in section 7.7.1.5. All patients, whether an ICD is implanted or not, should receive medical therapy as outlined in the full-text guidelines.
