Although individual centers have performed pPCI for many years, a significant number of patients with STEMI either do not receive this optimal treatment or do not receive it in a timely manner due to the small number of tertiary care centers with an around-the-clock (‘24/7‘) service. Large urban centers and rural areas, where tertiary care hospitals are restricted to specific regions, are less likely to have the capacity to deliver this treatment to the population as a whole (<a class="elsevierStyleCrossRef" href="#bib4">4</a>).</p><p id="para20" class="elsevierStylePara elsevierViewall">Thus, a pharmacoinvasive treatment strategy has emerged as an alternative for STEMI patients admitted to primary care centers.

Furthermore, mortality rates are still high outside major referral centers, with an estimated 1 death for every 5 to 7 cases (<a class="elsevierStyleCrossRef" href="#bib6">6</a>). Therefore, we recently developed a public STEMI network based on a pharmacoinvasive treatment strategy in the metropolitan area of São Paulo as a possible alternative to pPCI. In the present study, we sought to evaluate the rate and predictors of in-hospital mortality in a large population of STEMI patients who underwent pharmacoinvasive treatment.</p></span><span id="cesec20" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle70">METHODS</span><span id="cesec30" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle80">Patients and study protocol</span><p id="para40" class="elsevierStylePara elsevierViewall">Between November 2010 and October 2012, 567 patients with STEMI were transferred to a tertiary hospital (Hospital São Paulo, Escola Paulista de Medicina at Federal University of São Paulo) as part of a municipal primary care program for STEMI.

Those patients receiving thrombolysis were referred for an early invasive coronary angiography procedure regardless of successful reperfusion 3 to 24 hours after thrombolysis (i.e., elective or rescue PCI) according to clinical and electrocardiographic criteria.

Demographic and clinical data were entered into a database prospectively, and all quantitative coronary angiography data were analyzed by one experienced interventional cardiologist. Thrombolysis in myocardial infarction (TIMI) flow and blush grade were assessed as previously reported (<a class="elsevierStyleCrossRef" href="#bib8">8</a>,<a class="elsevierStyleCrossRef" href="#bib9">9</a>). Coronary artery disease (CAD) was defined as single- or multi-vessel disease according to the number of epicardial arteries with at least 1 lesion measuring ≥70% of the diameter of stenosis.</p><p id="para60" class="elsevierStylePara elsevierViewall">Chronic renal failure was defined as creatinine clearance <60 mL/min, estimated by the Cockcroft-Gault formula (<a class="elsevierStyleCrossRef" href="#bib10">10</a>). Anemia was defined as plasma hemoglobin measuring less than 13 mg/dL for males or 12 mg/dL for females (<a class="elsevierStyleCrossRef" href="#bib11">11</a>). The Global Registry of Acute Coronary Events (GRACE) score (<a class="elsevierStyleCrossRef" href="#bib12">12</a>) was calculated at admission, and the left ventricular ejection fraction (LVEF) was determined by echocardiography during hospitalization. Successful thrombolysis was defined as a culprit artery with TIMI flow grade 2-3 at the time of coronary angiography. Time intervals between chest pain and the administration of Tenecteplase (TNK; pain-to-needle time) and between the administration of TNK and coronary angiography (needle-to-balloon time) are expressed in hours.

This is especially true in large urban centers or rural areas, where a lack of access to tertiary healthcare may make the performance of timely pPCI difficult. The so-called pharmacoinvasive treatment strategy, consisting of thrombolysis with TNK and contemporary antithrombotic therapy administered before transport to a PCI-capable hospital, has emerged as an alternative to pPCI. The recommendation of prompt transfer to a referral center with a catheterization laboratory is deemed fundamental to the strategy's success, allowing for (i) immediate reperfusion in cases when thrombolysis fails; (ii) treatment for early reocclusion, which can affect as many as 30% of cases (<a class="elsevierStyleCrossRef" href="#bib14">14</a>); and, ultimately, (iii) early PCI (<24 hours) for patients with successful thrombolytic reperfusion but with severe residual stenosis. Compared with pPCI, this strategy has shown similar clinical outcomes (<a class="elsevierStyleCrossRefs" href="#bib15">15-17</a>). Accordingly, this strategy is strongly recommended by the European Society of Cardiology and ACC/AHA guidelines (class I and IIa, respectively) (<a class="elsevierStyleCrossRef" href="#bib1">1</a>,<a class="elsevierStyleCrossRef" href="#bib3">3</a>).</p><p id="para130" class="elsevierStylePara elsevierViewall">The present study represents one of the largest real-world studies relevant to this subject thus far and shows an in-hospital all-cause mortality rate of 5.8%. Other national, multicenter studies have reported mortality rates of 3.3% in patients who underwent elective PCI after thrombolysis, 7.6% in patients who underwent rescue PCI, and 5.6% in pPCI patients (<a class="elsevierStyleCrossRef" href="#bib18">18</a>,<a class="elsevierStyleCrossRef" href="#bib19">19</a>). In previous randomized multicenter studies comparing a pharmacoinvasive strategy with ischemia-driven PCI, in-hospital mortality rates ranged from 3.0% to 4.5%. These studies, however, also demonstrated shorter pain-to-needle and needle-to-balloon times (2 and 4 hours, respectively), which may explain, at least in part, their lower mortality rates (<a class="elsevierStyleCrossRef" href="#bib14">14</a>,<a class="elsevierStyleCrossRef" href="#bib20">20</a>). A remarkably low mortality rate was also observed in a recently published STREAM trial (<a class="elsevierStyleCrossRef" href="#bib21">21</a>), which compared pPCI with a pharmacoinvasive approach. This study randomized STEMI patients who had a clinical presentation for less than 3 hours and who were at least 60 minutes away from pPCI centers and found an overall mortality rate of 4.7% for both groups. Similar to previous results, such as those obtained in the TRANSFER AMI study (<a class="elsevierStyleCrossRef" href="#bib14">14</a>), and our own results, one-third of the STREAM patients required rescue catheterization.</p><p id="para140" class="elsevierStylePara elsevierViewall">In the present analysis, LVEF and the GRACE score emerged as significant predictors of mortality. Successful thrombolysis was achieved in over 65% of patients, similar to the rate reported in the STREAM trial, with a mortality rate of only 3.4% in this subgroup (significantly lower than the rate of 10.4% in patients with a baseline TIMI flow of 0-1). Therefore, this study showing a low mortality rate in patients who underwent successful thrombolysis is encouraging and stresses the potential importance of a pharmacoinvasive treatment strategy, especially in public hospitals and developing countries.</p><p id="para150" class="elsevierStylePara elsevierViewall">Regardless of achieving a similar optimal final TIMI flow after PCI (as a surrogate endpoint for PCI angiographic success) in both groups, grade 3 myocardial blush was observed significantly less often in non-survivors; thus, myocardial blush grade was also an important independent predictorof mortality. Restoring coronary microcirculation through the use of several available strategies and in light of ongoing studies (e.g., intracoronary abciximab and thrombectomy) has been a challenge for interventional cardiologists over the last several decades. Studies evaluating patients who underwent thrombolytic and mechanical reperfusion during STEMI showed a direct relationship between the degree of myocardial perfusion, as detected by the blush angiographic method, and mortality in short and long clinical follow-up periods (<a class="elsevierStyleCrossRef" href="#bib22">22</a>,<a class="elsevierStyleCrossRef" href="#bib23">23</a>).</p><p id="para160" class="elsevierStylePara elsevierViewall">Restoring microcirculation extends beyond the restoration of epicardial flow and depends on the optimization of adjunctive therapy, especially antiplatelet and antithrombotic therapy. Compared with the STREAM trial population, we achieved similar rates of final TIMI flow 2-3 even in a setting of a longer pain-to-needle time. Therefore, achieving a baseline TIMI flow of 3 along with a myocardial blush grade of 3 should be considered to indicate optimal reperfusion. This finding is in accordance with previous studies demonstrating a normal myocardial blush grade as a predictor of survival and left ventricular recovery in patients who undergo pPCI and rescue angioplasty (<a class="elsevierStyleCrossRefs" href="#bib24">24-28</a>).</p><p id="para170" class="elsevierStylePara elsevierViewall">Hemorrhagic complications are still a concern associated with this strategy. However, no significant difference was observed in randomized trials between this treatment strategy and other treatments (<a class="elsevierStyleCrossRef" href="#bib14">14</a>,<a class="elsevierStyleCrossRef" href="#bib20">20</a>,<a class="elsevierStyleCrossRef" href="#bib21">21</a>). In the STREAM trial, after the amendment of halving the TNK dosage in patients older than 75 years, there was no significant difference in hemorrhagic events between the groups. Hemorrhagic stroke and blood transfusion occurred in 0.5% and 2.9% of patients, respectively; in our study, these rates were 0.5% and 4.0%, respectively.</p><p id="para180" class="elsevierStylePara elsevierViewall">Although far from ideal because pPCI is considered the standard of care for STEMI patients, a pharmacoinvasive treatment strategy could be an alternative for achieving short pain-to-balloon times and, coupled with a structured healthcare network, could represent a highly important improvement in public health management of STEMI in Brazil. The present study is a step forward in adjusting the healthcare system in accordance with global standards to optimally assist the largest possible number of patients.</p><p id="para190" class="elsevierStylePara elsevierViewall">This study has several limitations. It was an observational and single-center study. A femoral artery approach was used in all cases, and bleeding criteria may underestimate the actual impact of this important complication on mortality. In addition, the use of radial access in pPCI has been associated with lower mortality rates (<a class="elsevierStyleCrossRef" href="#bib29">29</a>,<a class="elsevierStyleCrossRef" href="#bib30">30</a>). The multivariate analysis performed in this study cannot exclude residual confounding due to unmeasured or unknown variables. Finally, the generalizability of this study is limited because it can only be applied to STEMI patients who undergo a pharmacoinvasive treatment strategy according to the methods described in our protocol.</p><p id="para200" class="elsevierStylePara elsevierViewall">In this real-world, prospective study that included STEMI patients who underwent a pharmacoinvasive treatment strategy, in-hospital mortality rates were low at 5.8%. The GRACE score, LVEF, and myocardial blush grade were powerful predictors of mortality after administration of this pharmacoinvasive treatment strategy in the contemporary reperfusion era.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:6 [ 0 => array:2 [ "identificador" => "xpalclavsec1582065" "titulo" => "KEYWORDS" ] 1 => array:2 [ "identificador" => "cesec10" "titulo" => "INTRODUCTION" ] 2 => array:3 [ "identificador" => "cesec20" "titulo" => "METHODS" "secciones" => array:3 [ 0 => array:2 [ "identificador" => "cesec30" "titulo" => "Patients and study protocol" ] 1 => array:2 [ "identificador" => "cesec40" "titulo" => "Study objective and definitions" ] 2 => array:2 [ "identificador" => "cesec50" "titulo" => "Statistical analysis" ] ] ] 3 => array:3 [ "identificador" => "cesec60" "titulo" => "RESULTS" "secciones" => array:1 [ 0 => array:2 [ "identificador" => "cesec70" "titulo" => "Predictors of in-hospital mortality" ] ] ] 4 => array:2 [ "identificador" => "cesec80" "titulo" => "DISCUSSION" ] 5 => array:1 [ "titulo" => "REFERENCES" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2013-04-18" "fechaAceptado" => "2013-06-20" "PalabrasClave" => array:1 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "KEYWORDS" "identificador" => "xpalclavsec1582065" "palabras" => array:3 [ 0 => "Myocardial Infarction" 1 => "Mortality" 2 => "Pharmacoinvasive Therapy" ] ] ] ] "tieneResumen" => true "resumen" => array:1 [ "en" => array:2 [ "resumen" => "<span id="ceabs10" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle10">OBJECTIVES:</span><p id="spara50" class="elsevierStyleSimplePara elsevierViewall">To identify predictors of in-hospital mortality in patients with acute myocardial infarction undergoing pharmacoinvasive treatment.</p></span> <span id="ceabs20" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle20">METHODS:</span><p id="spara60" class="elsevierStyleSimplePara elsevierViewall">This was an observational, prospective study that included 398 patients admitted to a tertiary center for percutaneous coronary intervention within 3 to 24 hours after thrombolysis with tenecteplase.
