3 Importance of Prompt Treatment
Prompt treatment increases the likelihood of survival for patients with myocardial infarction with ST-segment elevation (Berger et al., 1999; Cannon et al., 2000, McNamara et al., 2006). McNamara et al., JACC, 2006

4 Mortality and Doorn to Balloon Time
Ting HH, et al. Circulation 2007;116:

5 Beyond a D2B of 90 minutes…. Every 15-min delay adds mortality
(Nallamothu 2007 NEJM 357:1631)‏

6 2008 ESC STEMI GUIDELINES Key Messages remain unchanged:
Early diagnosis Reperfusion therapy as soon as possible Optimal secondary prevention 2008 ESC GUIDELINES

7 Ritardo Evitabile (tempo decisionale)‏
Ritardo extraospedaliero sanitario Ritardo extraospedaliero NON sanitario Ritardo intraospedaliero Campagne educazionali Percorsi extraospedalieri Percorsi intraospedalieri

8 Fonti di possibili ritardi tra comparsa sintomi e inizio terapia riperfusiva
Problema Soluzione Ritardo del paziente: Tempo tra la comparsa sintomi e chiamata 118 Educazione del paziente Ritardo nel trasporto Strategia organizzativa 118 Da qui la necessità di realizzare una strategia organizzativa interospedaliera e territoriale che potesse coinvolgere ed inglobare tutti i tempi (dall’inizio del dolore del pz ed al tentativo di riapertura del vaso)- Ritardo inizio del trattamento Strategia organizzativa Inter-intraospedaliera 8

9 Strategia concordata:

10 Modello di Rete per l’emergenza coronarica
Obiettivi Favorire una diagnosi precoce, un trasporto rapido ed un ottimale trattamento riperfusivo a tutti i pazienti 10

14 Door to Balloon Times: Achieving 90 Minutes and Less
W. Douglas Weaver, MD President-Elect ACC November 2007 Una recente iniziativa americana chiamata DtB : an alliance for quality organizzata dall’ACC e AHA ha l’obiettivo di proporre alcune strategie operative sul territorio nazionale con lo scopo di raggiungere un DtB in almeno il 75% dei pz con STEMI 14

15 Strategies that Reduce Treatment Delays
1. ED physician activates the cath lab 2. Single call activates the cath lab 3. Cath lab team ready in minutes 4. Prompt data feedback for case review Pre-hospital ECG to activate the cath lab while patient is en route Having attending cardiologist always on site Core of the D2B campaign. The basic strategies are just the beginning… As more evidence is generated, the D2B Alliance may add new strategies. Lots of processes being uses successfully that are not on this list. 15

16 D2B Alliance Goal Goal: To achieve a door-to-balloon time of ≤ 90 minutes for at least 75% of non-transfer primary PCI patients with STEMI Here is our goal. Here is the essence of the goal: Excludes transfer patients Only STEMI patients Only Primary PCI hospitals 75% of all those folks are 90 minutes or less.

43 Illusion of reperfusion
In 1993, at the peak of the thrombolytic era, Lincoff and Topol wrote a provocative editorial wondering whether reperfusion was just an illusion. At that time, they estimated that only “25% or less” of patients treated by thrombolysis had an optimal reperfusion. Lincoff AM, Topol EJ. Illusion of reperfusion. Does anyone achieve optimal reperfusion during acute myocardial infarction? Circulation 1993;88:1361–74. defined as a rapid, complete, and sustained coronary recanalization with adequate myocardial tissue perfusion.

44 The No-Reflow Phenomenon: Defining the Problem
The no-reflow phenomenon is the inability to reperfuse a portion of the myocardium after re-establishment of patency of previously occluded epicardial coronary artery Despite the proven success of restoration of epicardial coronary blood flow in a reasonably timely fashion, reperfusion on the myocardial level is not accomplished in 50% of patients with STEMI. The common denominator of prevailing theories for this phenomenon is the development of myocardial microvascular dysfunction as a consequence of the primary epicardial event and/or perhaps of reperfusion per se Indeed, patients with no-reflow exhibit a higher prevalence of: 1) early post-infarction complications (arrhythmias, pericardial effusion, cardiac tamponade, early congestive heart failure); 2) left adverse ventricular remodelling; 3) late re-hospitalizations for heart failure; 4) mortality 44
