Eur Heart J 2012;33:

15 Reperfusion Therapy: Primary PCI
IIa IIb III Indicated in all patients with chest pain/discomfort of < 12 hrs and with persistent ST-segment elevation or (presumed) new LBBB A Should be considered if there is clinical and/or ECG evidence of ongoing ischemia if symptoms started > 12 hrs before C Reperfusion (PCI) in stable patients presenting > 12hrs to 24 hrs after symptom onset B PCI totally occluded infarcted artery in stable patients > 24 hrs after symptom onset without signs of ischemia is not recommended A Eur Heart J 2012;33:

16 Reperfusion Therapy: Primary PCI
IIa IIb III A Preferred reperfusion treatment if performed by an experienced team as soon as possible within 120 min of FMC Indicated for patients with cardiogenic shock and those with contraindications to fibrinolytic therapy irrespective of time delay B RESCUE PCI After failed fibronolysis in pts with large infarcts performed within 12 hrs A Eur Heart J 2012;33:

17 Dye strongly persistent
TIMI Myocardial Perfusion (TMP) Grades TMP Grade 3 TMP Grade 2 TMP Grade 1 TMP Grade 0 Normal ground glass appearance of blush Dye mildly persistent at end of washout Dye strongly persistent at end of washout Gone by next injection Stain present Blush persists on next injection No or minimal blush 6.2% p = 0.05 5.1% 4.4% Mortality (%) 2.0% n = 434 n = 79 n = 46 n = 203 Gibson et al, Circulation 1999

18 Advantages of Primary PCI
Higher initial reperfusion rates Lower recurrence rates of ischemia / infarction Less residual stenosis Less intracranial bleeding Defines coronary anatomy and LV function Utility when fibrinolysis contraindicated

19 Stents in STEMI A A Stenting is recommended (over balloon angioplasty
IIa IIb III A Stenting is recommended (over balloon angioplasty alone for primary PCI) I IIa IIb III A Drug-eluting Stent (DES) as an alternative to a bare metal stent (BMS) for primary PCI in STEMI * Consideration for the use of stents (DES or BMS) in STEMI should include the ability of the patient to comply with prolonged dual antiplatelet therapy, the bleeding risk in patients on chronic oral anticoagulation, and the possibility that the patient may need surgery during the ensuing year Eur Heart J 2012;33: 19

20 PCI for unprotected left main
PCI of the LM coronary artery using stents as an alternative to CABG may be considered in patients with isolated LM or LM plus single vessel disease, for pts. with ostial lesions and for pts. with co-morbidities (such as severe lung disease, prior thoracic surgery or poor CABG targets) that would make CABG high risk or unlikely to be successful I IIa IIb III B * Conversely, CABG for uLMCA may be relatively more favorable for patients with LMCA plus multi-vessel disease, distal/bifurcation LMCA lesions, or low surgical risk with good chance of technical success. 20

21 Primary PCI: Adjunctive Therapies
Antiplatelet antagonist Aspirin oral or i.v. ADP receptor blocker in addition to aspirin Clopidogrel Prasugrel, in naïve clopidogrel pts., if no history of stroke/TIA, age<75 yrs. Ticagrelor GPIIb/IIIa antagonist abciximab tirofiban eptifibatide Antithrombin co-therapy Enoxaparin Unfractioned heparin Bivalirudin Fondaparinux Adjunctive devices Thrombus aspiration Eur Heart J 2012;33:

24 Terapie di routine nella fase acuta, subacuta e a lungo termine: STEMI
Aspirina (mantenimento mg/die) Eparine Prasugrel/Ticagrelor/Clopidogrel ( se PCI, dose mantenimento) Anticoagulanti orali ( se pz von valvole prostetiche, FA) Beta-bloccanti ( NO in ipotensione) Ca-antagonisti ( se beta-bloccanti controindicati) Ace-inibitori/ ARBs Statine ad alte dosi Antagonisti dei recettori del aldosterone

25 Treatment Strategy for Right Ventricular Ischemia/Infarction
Maintain right ventricular preload Volume loading (IV normal saline) Avoid use of nitrates and diuretics Maintain AV synchrony (AV sequential pacing for symptomatic high-degree heart block unresponsive to atropine) Prompt cardioversion for hemodynamically significant SVT Inotropic support Dobutamine (if cardiac output fails to increase after volume loading)

26 Terapia in UA/NSTEMI Early Conservative Strategy? Vs. Early Invasive Strategy?

27 Early Conservative Versus Invasive Strategies
Two different treatment strategies, termed “early conservative” and “early invasive” have evolved for patients with UA/NSTEMI. In the early conservative strategy, coronary angiogrpahy is reserved for patients with evidence of recurrent ischemia (angina or ST-segment changes at rest or with minimal activity) or a strongly positive stress test despite vigorous medical therapy. In the early invasive strategy, patients without clinically obvious contraindications to coronary revascularization are routinely recommended for early coronary angiography and angiographically directed revascularization if possible.

28 Early Invasive Strategy
Coronary angiography class I - Level Evidence A Early Invasive Strategy Recurrent angina-ischemia at rest or with low level activities despite intensive anti-ischemic therapy Elevated TnT or TnI New or presumably new ST-segment depression Recurrent angina/ischemia with CHF symptoms High-risk findings on noninvasive stress testing Depressed LV systolic function Hemodynamic Instability Sustained Ventricular Tachycardia PCI within 6 months Prior CABG ACC/AHA Practice Guidelines

29 Early Conservative Strategy
Coronary angiography is reserved for patients with: Evidence of recurrent ischemia - angina at rest or with minimal activity - dynamic ST-segment changes Strongly positive stress-test (despite vigorous medical therapy) ACC/AHA Practice Guidelines

36 Antiplatelet agents: Aspirin
IIa IIb III Aspirin is recommended for all patients presenting with NSTE-ACS without contraindication at an initial loading dose of 160–325 mg (non-enteric), and at a maintenance dose of 75–100 mg long-term. A Eur Heart J 2007;28:1598–1660 I IIa IIb III Aspirin should be given to all patients without contraindications at an initial loading dose of 150–300 mg, and at a maintenance dose of 75–100 daily long-term regardless of treatment strategy. A Hamm C W et al. Eur Heart J 2011;32:

37 Antiplatelet agents: P2Y12 receptor inhibitors
Clopidogrel I IIa IIb III For all patients, an immediate 300 mg loading dose of clopidogrel is recommended, followed by 75 mg clopidogrel daily. Clopidogrel should be maintained for 12 months unless there is an excessive risk of bleeding A In patients considered for an invasive procedure/PCI, a loading dose of 600 mg of clopidogrel may be used to achieve more rapid inhibition of platelet function B Eur Heart J 2007;28:1598–1660 Hamm C W et al.

52 PLATO TRIAL: REMARKS Ticagrelor: unsolved issues
Given that both prasugrel and ticagrelor appear superior to clopidogrel, how would they compare against each other, especially in clopidogrel nonresponders? The relative antiplatelet effects of prasugrel versus high-dose clopidogrel are unknown at least in terms of outcomes Gurbel PA, et al The ONSET/OFFSET Study Circulation 2009;120: In December 2010 the FDA requested additional ASA dose analyses from PLATO which were provided in January Ticagrelor appear to be even more effective if used with lower dose maintenance ASA. (Results still unpublished). .

53 Glycoprotein IIb/IIIa receptor inhibitors
The choice of combination of oral antiplatelet agents, a GP IIb/IIIa receptor inhibitor, and anticoagulants should be made in relation to the risk of ischemic and bleeding event Among patients who are already treated with dual (oral) antiplatelet therapy the addition of a a GP IIb/IIIa receptor inhibitor for high-risk PCI (elevated troponin, visible thrombus) is recommended if the risk of bleeding is low Eptifibatide or tirofiban added to aspirin should be considered prior to angiography in high risk patients not preloaded with P2Y12 inhibitors In high-risk patients eptifibatide or tirofiban may be considered prior to early angiography in addition to dual (oral) antiplatelet therapy, if there is ongoing ischemia and the risk of bleeding is low. GP IIb/IIIa receptor inhibitor are not recommended routinely before angiography in an invasive treatment strategy GP IIb/IIIa receptor inhibitor are not recommended routinely for patients on dual (oral) antiplatelet therapy treated conservately B C C A A Hamm C W et al.

57 Clinical Implications
Much of the evidence supporting the use of glycoprotein IIb/IIIa agents comes from an era prior to routine early invasive management Given the increased frequency of upstream oral P2Y12 inhibitor use, the upstream use of GP IIb/IIIa inhibitors (in combination with or in place of oral P2Y12 inhibitors) has been questioned because of concerns about excessive bleeding risk. Further reviews are needed to identify certain subgroups of patients who are likely to derive a net clinical benefit from upstream GP IIb/IIIa inhibitor use in an early invasive strategy

Precoci Morte improvvisa Fase acuta Aritmie Insufficienza mitralica: necrosi dei muscoli papillari Scompenso cardiaco Shock cardiogeno Giorni successivi Estensione dell’infarto, Angina Embolie polmonari o sistemiche Complicanze di tipo meccanico Pericardite epistenocardica Complicanze post-acute Aritmie ipercinetiche, Sindrome di Dressler ( Pericardite di Dressler) Recidiva di infarto miocardico.

64 Pericardite Epistenocardica
Quasi esclusivamente dopo infarto transmurale Segno indiretto di gravità del danno miocardico ischemico Clinica Ripresa di dolore toracico (terza, quarta giornata, entro i primi sette giorni) Dolore è sensibile alle variazioni posturali, ai colpi di tosse alle profonde inspirazioni. 10% dei casi sfregamento pericardico Si può associare: Versamento pericardico Febbre Leucocitosi VES ECG Modifiche della fase di ripolarizzazione ventricolare Tachicardia sinusale Aritmie sopraventricolari Accentuazione del sopraslivellamento del tratto ST (derivazioni diverse da quelle dell’infarto ed a concavità superiore) Diagnosi differenziale Estensione dell’infarto Fenomeni embolici polmonari Broncopolmonite

65 Sindrome di Dressler Compare da 1-8 settimane dopo l’infarto Clinica
Malessere generale Febbre Dolore pericardico Leucocitosi ↑VES Versamento pericardico Causa non definita chiaramente Riscontro di anticorpi contro il tessuto cardiaco fa pensare ad una genesi autoimmunitaria Risponde prontamente alla terapia steroidea

66 Pericardite post-infartuale
Trattamento Antiinfiammatori (aspirina ed indometacina) Diuretici (riduzione del versamento pericardico se presente) Corticosteroidi solo in caso di refrattarietà alla terapia con FANS (ritardano il processo di cicatrizzazione → rischio rottura parte ventricolare)
