Abstract
BACKGROUND Although a door-to-balloon (D2B) time ≤90 min is recognized as a key indicator of timely reperfusion for patients with ST-segment elevation myocardial infarction (STEMI), it is unclear whether regional disparities in the prognostic value of D2B remain in contemporary Japan. METHODS AND RESULTS We retrospectively analyzed 17,167 STEMI patients (mean [±SD] age 68±13 years, 77.6% male) undergoing primary percutaneous coronary intervention. With reference to the Japanese median population density of 1,147 people/km2, patients were divided into 2 groups: rural (n=6,908) and urban (n=10,259). Compared with the urban group, median D2B time was longer (70 vs. 62 min; P<0.001) and the rate of achieving a D2B time ≤90 min was lower (70.7% vs. 75.4%; P<0.001) in the rural group. In-hospital mortality was lower for patients with a D2B time ≤90 min than >90 min, regardless of residential area, whereas multivariable analysis identified prolonged D2B time as a predictor of in-hospital death only in the rural group (adjusted odds ratio 1.57; 95% confidence interval 1.18-2.09; P=0.002). Importantly, the rural-urban disparity in in-hospital mortality emerged most distinctively among patients with Killip Class IV and a D2B time >90 min. CONCLUSIONS These data suggest that there is a substantial rural-urban gap in the prognostic significance of D2B time among STEMI patients, especially those with cardiogenic shock and a prolonged D2B time.

Implementation of a Comprehensive ST-Elevation Myocardial Infarction Protocol Improves Mortality Among Patients With ST-Elevation Myocardial Infarction and Cardiogenic Shock. Am J Cardiol 2020; 134:1-7. [PMID: 32933753 DOI: 10.1016/j.amjcard.2020.08.012] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 08/02/2020] [Accepted: 08/04/2020] [Indexed: 12/16/2022]
Abstract
Mortality in patients with STEMI-associated cardiogenic shock (CS) is increasing. Whether a comprehensive ST-elevation myocardial infarction (STEMI) protocol (CSP) can improve their care delivery and mortality is unknown. We evaluated the impact of a CSP on incidence and outcomes in patients with STEMI-associated CS. We implemented a 4-step CSP including: (1) Emergency Department catheterization lab activation; (2) STEMI Safe Handoff Checklist; (3) immediate catheterization lab transfer; (4) and radial-first percutaneous coronary intervention (PCI). We studied 1,272 consecutive STEMI patients who underwent PCI and assessed for CS incidence per National Cardiovascular Data Registry definitions within 24-hours of PCI, care delivery, and mortality before (January 1, 2011, to July 14, 2014; n = 723) and after (July 15, 2014, to December 31, 2016; n = 549) CSP implementation. Following CSP implementation, CS incidence was reduced (13.0% vs 7.8%, p = 0.003). Of 137 CS patients, 43 (31.4%) were in the CSP group. CSP patients had greater IABP-Shock II risk scores (1.9 ± 1.8 vs 2.8 ± 2.2, p = 0.014) with otherwise similar hemodynamic and baseline characteristics, cardiac arrest incidence, and mechanical circulatory support use. Administration of guideline-directed medical therapy was similar (89.4% vs 97.7%, p = 0.172) with significant improvements in trans-radial PCI (9.6% vs 44.2%, p < 0.001) and door-to-balloon time (129.0 [89:160] vs 95.0 [81:116] minutes, p = 0.001) in the CSP group, translating to improvements in infarct size (CK-MB 220.9 ± 156.0 vs 151.5 ± 98.5 ng/ml, p = 0.005), ejection fraction (40.8 ± 14.5% vs 46.7 ± 14.6%, p = 0.037), and in-hospital mortality (30.9% vs 14.0%, p = 0.037). In conclusion, CSP implementation was associated with improvements in CS incidence, infarct size, ejection fraction, and in-hospital mortality in patients with STEMI-associated CS. This strategy offers a potential solution to bridging the historically elusive gap in their care.

Abstract
An 89-year-old woman appeared to have acute coronary syndrome at the left main trunk (LMT) complicated with severe aortic stenosis, moderate-severe mitral regurgitation, depressed left ventricular (LV) function, and multivessel disease. Because of sustained hypotension even under intra-aortic balloon pumping support during emergency coronary angiograhy, we performed primary percutaneous coronary intervention solely for the LMT lesion using a bare metal stent, leading to recovery from the shock state. On the second hospital day, based on our heart-team consensus, we performed aortic valve replacement and coronary artery bypass grafting surgery, and added edge-to-edge repair (Alfieri stitch) of the mitral valve, resulting in complete revascularization and dramatically improved LV function.

Abstract
Despite advances in the treatment of patients with acute coronary syndromes, there has been no significant decrease in the incidence of cardiogenic shock, while its mortality remains frustratingly high. Shock is a progressive state of hypotension (systolic blood pressure <90 mm Hg) lasting at least 30 minutes, which leads to systemic hypoperfusion. It is more common in patients with ST-segment elevation myocardial infarction than in patients with other acute coronary syndromes. Revascularization is associated with better outcomes than intensive medical therapy, especially in patients <75 years of age with cardiogenic shock. Adjunctive therapies include inotropes, vasopressor therapy, intra-aortic balloon pump counterpulsation, and IIb/IIIa blockade to prevent no-reflow phenomenon during primary percutaneous transluminal coronary angioplasty. Other adjunctive therapies which are investigated are improved mechanical support devices, and as medical therapy for myocyte protection nicorandil, glucose/insulin/potassium infusions and direct inhibition of Na+/H+ exchanger.

Abstract
The intra-aortic balloon pump (IABP), which is the main representative of the counterpulsation technique, has been an invaluable tool in cardiologists' and cardiac surgeons' armamentarium for approximately half a century. The IABP confers a wide variety of vaguely understood effects on cardiac physiology and mechano-energetics. Although, the recommendations for its use are multiple, most are not substantially evidence-based. Indicatively, the results of recently performed prospective studies have put IABP's utility in the setting of post-infarction cardiogenic shock into question. However, the particular issue remains open to further research. IABP support in high-risk patients undergoing PCI is associated with favorable long-term clinical outcome. In cardiac surgery, the use of IABP in cases of peri-operative low-output syndrome, refractory angina or ischemia-related mechanical complications is a usual, but poorly justified strategy. Anecdotal cases of treatment of incessant ventricular arrhythmias, reversal of right ventricular dysfunction and partial myocardial recovery have also been reported with its use. Converging data demonstrate the potential of safe long-term IABP support as a bridge to decision making or a bridge to transplantation modality in patients with heart failure. The feasibility of IABP insertion via other than the femoral artery sites enhances this potential. Despite the fact that several other counterpulsation devices have been developed and tested overtime none has managed to substitute the IABP, which continues to be most frequently used mechanical assist device.

Abstract
BACKGROUND AND PURPOSE Percutaneous cardiopulmonary support (PCPS) is useful in the rescue of patients who have experienced severe cardiogenic shock. We investigated the predictive factors of survival among patients with cardiogenic shock requiring PCPS. METHODS AND SUBJECTS We enrolled 29 patients (21 men and 8 women, 73 ± 10 years old) with circulatory collapse complicating acute myocardial infarction (AMI) requiring PCPS. Fifteen patients could be weaned from PCPS and survived for more than 1 month (group A), while the other 14 patients could not (group B). We investigated the initial PCPS settings, and performed the appropriate laboratory tests. Hemodynamic data and arterial base excess (BE) values were recorded throughout the PCPS treatment. RESULTS There was no difference in the laboratory test results or the left ventricular ejection fraction between the groups at the start of PCPS. PCPS flow (l/min) was significantly lower in group A than in group B at the 24th hour of PCPS (2.26 ± 0.36 and 2.54 ± 0.41, respectively). There were no differences in blood pressure between the groups. During the 24-h period prior to the end of PCPS, BE remained almost normal in group A. In group B, BE decreased continuously throughout the same period. BE values were significantly lower compared to those obtained in group A 12h prior to the end of PCPS. CONCLUSIONS A reduction in PCPS flow without hemodynamic collapse may allow for successful weaning from PCPS. BE may be a potent factor in determining when to terminate PCPS.

Abstract
BACKGROUND Mortality in acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) approaches 70 - 80%, regardless of the type of pharmacological treatment. Early revascularisation improves survival in AMI with CS. Our aim is to assess the predictors of mid-term outcome after percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) and CS. METHODS Forty-one patients who underwent primary or rescue PCI for CS were analysed comparing their baseline, angiographic, PCI data, 30-day and 1-year survival. RESULTS There were no significant differences between survivors and non-survivors in baseline characters, except for more number of transfer admissions (P= 0.0005), and cardiopulmonary resuscitations (P= 0.015) in the later group. The mean time between myocardial infarction (MI) onset to shock and MI onset to revascularisation were 12.8 ± 12.9 hours and 17.0 ± 16.8 hours, respectively. Patients with better pre-procedure thrombolysis in myocardial infarction (TIMI) flow in the infarct-related artery (IRA) had better survival (P= 0.0005). Successful PCI was achieved in 48.8% of patients. The 30-day mortality was 56.1% and all were prior to hospital discharge. Patients with successful PCI had better short-term survival in comparison with patients with failed PCI (80% vs 9.6%). Eighteen patients who survived at 30 days were followed up for 12-72 months (mean 28.5 ± 5.4 months). Fifteen patients survived at 1 year after PCI and all were in good functional status. CONCLUSION Mortality remains high even with PCI. Achieving IRA patency with TIMI 3 flow is the main determinant of survival. Survival and functional status are good in patients who are discharged from hospital.

Abstract
Total occlusion of unprotected left main coronary artery (LMCA) is rarely encountered in clinical practice and the incidence cannot be determined precisely, since most of the patients die before hospital admission. Malignant arrhythmia, cardiogenic shock or sudden death due to pump failure develops in most of these patients. The cases complicated by cardiogenic shock have bad prognosis in both the short and long term, despite the advancements in reperfusion treatments. Successful treatment of sudden total occlusion of unprotected LMCA has been rarely reported. Over the last decade, many cases and comparisons in patients with LMCA lesions were reported on percutaneous interventions for unprotected LMCA using different stent and stenting procedures or in comparison to coronary bypass surgery. On the other hand, these patients either had stable coronary artery disease or a partially occluded LMCA in the setting of acute coronary syndromes with well supporting collateral flow. In our case, a 50 year-old male patient with cardiogenic shock and extensive anterior ST-elevation myocardial infarction due to acute total occlusion of unprotected LMCA, who was not receiving collateral flow from the right coronary system, was treated successfully through primary percutaneous coronary angioplasty, was presented. In our case, there was an totally occluded unprotected LMCA without any supportive coronary flow to left system. In this regard, our case is unique in literature.

Abstract
Cardiogenic shock continues to be the most common cause of death in patients hospitalized with acute myocardial infarction. It has also been frequently associated with ST-segment elevation myocardial infarction (STEMI) and patients with co-morbidities. Cardiogenic shock presents with low systolic blood pressure and clinical signs of hypoperfusion. Rapid diagnosis and supportive therapy in the form of medications, airway support and intra-aortic balloon counterpulsation is required. Initial stabilization can be followed by reperfusion by fibrinolytic therapy, emergent percutaneous intervention (PCI) or coronary artery bypass grafting (CABG). The latter two have been found to decrease mortality in the long term. Research is being carried out on the role of inflammatory mediators in the clinical manifestation of cardiogenic shock. Mechanical support devices also show promise in the future.

Abstract
Cardiogenic shock is often a devastating consequence of acute myocardial infarction (MI) and portends to significant mortality and morbidity. Despite improvements in expediting the time to treatment and enhancements in available medical therapy and reperfusion techniques, cardiogenic shock remains the most common cause of mortality following MI. Post-MI cardiogenic shock most commonly occurs as a consequence of severe left ventricular dysfunction. Right ventricular (RV) MI must also be considered. Mechanical complications including acute mitral regurgitation, ventricular septal rupture, and ventricular free-wall rupture can also lead to cardiogenic shock. Rapid diagnosis of cardiogenic shock and its underlying cause is pivotal to delivering definitive therapy. Intravenous vasoactive agents and mechanical support devices may temporize the patient's hemodynamic status until definitive therapy by percutaneous or surgical intervention can be performed. Despite prompt management, post-MI cardiogenic shock mortality remains high.

Abstract
BACKGROUND A pooled analysis in cardiogenic shock due to acute coronary syndromes is desirable to assess the effect of early revascularization (ERV) across all ages and a wide spectrum of disease severity. METHODS Only two randomized controlled trials (RCT), i.e. SMASH and SHOCK, met the inclusion criteria and were combined for a pooled analysis using individual patient data (n = 348). RESULTS SMASH patients (n = 54, 16%) had more severe disease than SHOCK patients (n = 294, 84%). After adjustment for age, anoxic brain damage, non-inferior myocardial infarction, prior coronary artery bypass graft surgery, renal failure, systolic blood pressure, and selection for coronary angiography, one-year mortality was similar (relative risk SHOCK versus SMASH 0.87, 95% CI: 0.61-1.25). Relative risk of one-year death for ERV versus initial medical stabilization was 0.82 (95% CI: 0.70-0.96). There was no significant difference in the treatment effect by age (≤75 years relative risk at one year 0.79, 95% CI: 0.63-0.99; > 75 years relative risk at one year 0.93, 95% CI: 0.56-1.53; interaction P = 0.10). CONCLUSIONS Only two RCT have been published emphasizing the difficulty of enrolling critically ill patients. Despite large differences in shock severity, ERV benefit is similar across all ages and not significantly different for the elderly.

Abstract
BACKGROUND Cardiogenic shock (CS) is a severe complication of acute myocardial infarction (AMI), associated with a high mortality. A significant improvement in survival has been reported with immediate coronary revascularization. However, there is no clear evidence of such an improvement amongst older patients. The aim of our work was to evaluate in-hospital and long-term outcomes in the group of elderly AMI patients with CS (≥75 years old). METHODS We collected data of 157 consecutive AMI patients with CS who underwent percutaneous coronary intervention (PCI) and compared clinical and procedural characteristics and in-hospital and long-term outcomes between patients <75 years and patients ≥75 years old. RESULTS There were 58 patients (36.9%) with age ≥75 years and 99 patients (63.1%) with age <75 years. Patients were followed up for an average period of 34 months (range 5-69). In-hospital and long-term mortality was significantly higher in the older group (55 vs. 25%, P < 0.0001; and 62.1 vs. 37.3%, P = 0.005, respectively). Multivariate predictors of in-hospital mortality were age ≥75 years (hazard ratio 1.81, 95% CI 1.006-3.27, P = 0.04) and PCI failure (hazard ratio 2.67, 95% CI 1.34-5.307, P = 0.005), whereas, the only multivariate predictor of long-term mortality was PCI failure (hazard ratio 2.88, 95% CI 1.52-5.46, P = 0.001). Age ≥75 years showed only a trend toward statistical significance (hazard ratio 1.62, 95% CI 0.96-2.76, P = 0.07). CONCLUSIONS In elderly AMI patients with CS, PCI can be performed with an acceptable risk that seems lower than that reported in most previous studies.

Abstract
BACKGROUND Significant regional variation in procedural frequencies has led to the development of the RAND and American College of Cardiology/American Heart Association (ACC/AHA) guidelines; however, they may be difficult to apply in clinical practice. The University of Maryland Revascularization Appropriateness Score (RAS) was created to address the need for a simplified point scoring system. HYPOTHESIS The study was undertaken to compare revascularization appropriateness ratings yielded by the RAND Expert Panel Ratings, ACC/AHA guidelines, and the University of Maryland RAS. METHODS We applied these three revascularization appropriateness scoring systems to 153 catheterization laboratory patients with a variety of cardiac diagnoses and treatments. For each patient, appropriateness scores assigned by each of the three systems were compared with each other and with the actual treatment delivered. Concordance of care with appropriateness score was then correlated with outcome. RESULTS There were significant differences among all three scoring systems in their ratings and in the concordance of treatment with appropriateness rating. When treatment provided was concordant with RAND ratings, there was a lower occurrence of subsequent coronary artery bypass grafting (CABG), the composite end point of either CABG or percutaneous transluminal coronary angioplasty (PTCA), and the composite end point of death, myocardial infarction (MI), or revascularization. When treatment was concordant with the ACC/AHA guidelines, there was lower occurrence of all-cause mortality, PTCA, the composite end point of either CABG or PTCA, and the composite end point of death, MI, or revascularization. When treatment provided was concordant with the RAS, there was lower occurrence of cardiac death, all-cause death, CABG, the composite end point of either CABG or PTCA, and the composite end point of death, MI, or revascularization. CONCLUSIONS The RAS is a simple scoring system to assess revascularization appropriateness. When the RAND, ACC/AHA, and RAS systems are compared in a catheterization laboratory population, they rate the same patient differently and vary in their correlation of appropriateness rating with outcome.

Abstract
Cardiogenic shock is defined as profound circulatory failure resulting in insufficient tissue perfusion to meet resting metabolic demands. It occurs in approximately 7.5% of patients with acute myocardial infarction. Treatment strategies include inotropic agents, use of intra-aortic balloon counterpulsation, and revascularization. Current evidence supports the use of primary angioplasty. Surgery should be considered in patients with triple-vessel disease. If early catheterization is not available, thrombolytic therapy should be given to eligible patients and transfer to an interventional facility should be considered. Effective therapy for shock must also include a prevention strategy. This requires identification of patients at high risk for shock development and selection of patients who are candidates for aggressive intervention.

Abstract
BACKGROUND Primary percutaneous coronary intervention (PCI) for ST elevation myocardial infarction (STEMI) improves outcome in comparison to fibrinolysis. However, it is unclear whether patients treated in interventional facilities with 24-h primary PCI service have lower rates of adverse events. METHODS We analyzed data of consecutive patients with STEMI prospectively enrolled in the German Acute Coronary Syndromes registry between July 2000 and November 2002 who were admitted to hospitals with catheterisation laboratory. RESULTS Overall 6,350 patients were divided into two groups: 2,779 (43.8%) were treated in hospitals with and 3,571 (56.2%) without 24-h on-call cardiac catheter laboratories. 83.0% of the patients at facilities with and only 69.9% of the patients at facilities without 24-h PCI service received early reperfusion therapy (P < 0.001). Hospital death (7.4% vs. 9.9%, P < 0.001), non-fatal myocardial reinfarction (2.5% vs. 6.4%, P < 0.0001) and stroke (0.3 vs. 1.0%, P < 0.01) occurred significantly less often in patients treated in hospitals with 24-h primary PCI service. After adjustment for the confounding factors in the propensity score analysis the 24-h on-call strategy remained superior for the combined endpoint of death, reinfarction and stroke (OR 0.63, 95% CI 0.54-0.75). CONCLUSIONS In clinical practice the rate of patients receiving reperfusion therapy was significantly higher in hospitals with 24-h primary PCI service which was associated with an improved in-hospital outcome. Though the data was collected at a time that does not completely represent current clinical practice, these results could have an impact on planning efficient infarct networks in the future.

Abstract
BACKGROUND The ideal revascularization strategy (bypass surgery versus percutaneous coronary intervention [PCI]) for patients with cardiogenic shock in the setting of left main coronary artery disease is unknown. METHODS The Should We Emergently Revascularize Occluded Coronaries for Cardiogenic Shock Trial and Registry included 164 patients with left main disease who underwent revascularization. Although the standard of care at the time and the trial protocol recommended coronary artery bypass graft surgery for patients with left main disease, the revascularization strategy (79 coronary artery bypass graft surgery and 85 PCI) was individualized for each patient by site investigators. RESULTS The median time from myocardial infarction to revascularization was 24.3 hours (interquartile range, 8.7 to 82.5 hours) in the surgical group and 7.4 hours (interquartile range, 3.7 to 19.5 hours) in the PCI group (p < 0.05). Overall 30-day survival with surgery in this setting was 54% (95% confidence interval, 0.43 to 0.69) and was significantly superior to the 14% (95% confidence interval, 0.09 to 0.35) in the PCI group (p <or= 0.001). When the left main was the infarct-related artery, the 30-day survival rate was 40% in the surgical group (n = 6) and 16% in the PCI group (n = 15; p = 0.03). Coronary artery bypass graft surgery (hazard ratio, 0.41; 95% confidence interval, 0.22 to 0.77; p = 0.006) and age (per 10 years, hazard ratio, 1.04; 95% confidence interval, 1.01 to 1.08; p = 0.02) were independently associated with 30-day survival. CONCLUSIONS Coronary artery bypass graft surgery appeared to provide a survival advantage over PCI at 30-day follow-up in patients with left main coronary artery disease. The impact of current PCI strategies on this subgroup is undetermined.

Abstract
Background—
There exist few studies that characterize contemporary clinical features and outcomes or risk factors for operative mortality in cardiogenic shock (CS) patients undergoing coronary artery bypass grafting (CABG).
Methods and Results—
We evaluated data of 708 593 patients with and without CS undergoing CABG enrolled in the Society of Thoracic Surgeons National Cardiac Database (2002–2005). Clinical, angiographic, and operative features and in-hospital outcomes were evaluated in patients with and without CS. Logistic regression was used to identify predictors of operative mortality and to estimate weights for an additive risk score. Patients with preoperative CS constituted 14 956 (2.1%) of patients undergoing CABG yet accounted for 14% of all CABG deaths. Operative mortality in CS patients was high and surgery specific, rising from 20% for isolated CABG to 33% for CABG plus valve surgery and 58% for CABG plus ventricular septal repair. Although mortality for CABG surgery overall declined significantly over time (
P
for trend <0.0001), mortality for CS patients undergoing CABG did not change significantly during the 4-year study period (
P
=0.07). Factors associated with higher death risk for CS patients undergoing CABG were identified by multivariable analysis and summarized into a simple bedside risk score (c statistic=0.74) that accurately stratified those with low (<10%) to very high (>60%) mortality risk.
Conclusions—
Patients with CS represent a minority of those undergoing CABG yet have persistently high operative risks, accounting for 14% of deaths in CABG patients. Estimation of patient-specific risk of mortality is feasible with the simplified additive risk tool developed in our study with the use of routinely available preprocedural data.

Abstract
Patients who develop cardiogenic shock after acute myocardial infarction have a very high mortality rate despite early reperfusion therapy. Hemodynamic stabilization can often only be achieved by implanting a mechanical circulatory support system. When, in cases representing expansive myocardial impairment without any chance of recovery, pharmacological therapy and the use of percutaneous assist devices have failed, the implantation of a total artificial heart is indicated. We report our first experiences with this extensive and innovative method of managing irreversible cardiogenic shock patients. The CardioWest total artificial heart was implanted in 5 patients (male; mean age, 50 years). All patients were in irreversible cardiogenic shock despite maximum dosages of catecholamines, an intra-aortic balloon pump and/or a femoro-femoral bypass. In all patients early reperfusion therapy was performed. After implantation of the Cardio West system, all dysfunctional organ systems rapidly recovered in all patients. Four of 5 patients underwent successful heart transplantation after a mean support time of 156 days. One patient died because of enterocolic necroses caused by an embolic event after termination of dicumarol therapy. In summary, our first experiences justify this extensive management in young patients who would otherwise have died within a few hours.

Abstract
In patients with cardiogenic shock (CS) complicating acute myocardial infarction, echocardiographic and angiographic findings are used to aid diagnosis, determine prognosis, and guide management. The purpose of this analysis from the Should we emergently revascularize Occluded Coronary arteries for Cardiogenic ShocK (SHOCK) trial is to identify relations between the angiographic and echocardiographic features of patients with CS. Such an analysis of the correlations between echocardiographic and angiographic findings in patients with CS may provide insights into the etiology and treatment of CS. In 302 randomized patients, an echocardiogram and an angiogram before revascularization were available in 127 patients. Although the median ejection fraction derived by echocardiography and left ventricular angiography was identical (30%), the positive correlation was weak (R2 = 0.209, p = 0.019). Patients with a larger number of diseased vessels had worse mitral regurgitation (MR) by echocardiography (p = 0.005). There was a significant but weak association between left ventricular angiographic MR grade and echocardiographic MR severity (R2 = 0.162, p = 0.015), but there was no association between culprit vessel and degree of MR. In conclusion, worse coronary artery disease is associated with more severe MR. Echocardiography and angiography are valuable and result in similar estimated ejection fractions in a large cohort, but there is wide variation between the techniques in patients.

Abstract
BACKGROUND The Should We Emergently Revascularize Occluded Coronaries for Cardiogenic Shock (SHOCK) trial demonstrated the survival advantage of emergency revascularization versus initial medical stabilization in patients developing cardiogenic shock after acute myocardial infarction. The relative merits of coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) in patients with shock have not been defined. The objective of this analysis was to compare the effects of PCI and CABG on 30-day and 1-year survival in the SHOCK trial. METHODS AND RESULTS Of the 302 trial patients, 128 with predominant left ventricular failure had emergency revascularization. The selection of revascularization procedures was individualized. Eighty-one patients (63.3%) had PCI, and 47 (36.7%) had CABG. The median time from randomization to intervention was 0.9 hours (interquartile range [IQR], 0.3 to 2.2 hours) for PCI and 2.7 hours (IQR, 1.3 to 5.5 hours) for CABG. Baseline demographics and hemodynamics were similar, except that there were more diabetics (48.9% versus 26.9%; P=0.02), 3-vessel disease (80.4% versus 60.3%; P=0.03), and left main coronary disease (41.3% versus 13.0%; P=0.001) in the CABG group. In the PCI group, 12.3% had 2-vessel and 2.5% had 3-vessel interventions. In the CABG group, 84.8% received > or =2 grafts, 52.2% received > or =3 grafts, and 87.2% were deemed completely revascularized. The survival rates were 55.6% in the PCI group compared with 57.4% in the CABG group at 30 days (P=0.86) and 51.9% compared with 46.8%, respectively, at 1 year (P=0.71). CONCLUSIONS Among SHOCK trial patients randomized to emergency revascularization, those treated with CABG had a greater prevalence of diabetes and worse coronary disease than those treated with PCI. However, survival rates were similar. Emergency CABG is an important component of an optimal treatment strategy in patients with cardiogenic shock, and should be considered a complementary treatment option in patients with extensive coronary disease.

Abstract
AIMS To determine clinical correlates and optimal treatment strategy in patients with cardiogenic shock (CS) on admission. METHODS AND RESULTS In SHould we emergently revascularize Occluded Coronaries in cardiogenic shocK? (SHOCK) trial and registry patients with left ventricular (LV) dysfunction (n=1053), CS on admission occurred in 26% of directly admitted patients (n=166/627). Time from myocardial infarction to CS was shorter, initial haemodynamic profile poorer, and aggressive treatment less frequent in CS on admission than in delayed CS patients. CS on admission patients constituted a smaller relative proportion (11%) of the transferred (n=48/426) when compared with the directly admitted cohort (P<0.001). In-hospital mortality was higher (75 vs. 56%; P<0.001) with more rapid death (24-h mortality 40 vs. 17%; P<0.001) in CS on admission than in delayed CS patients. Emergency revascularization reduced in-hospital mortality in CS on admission (60 vs. 82%; P=0.001) and in delayed CS patients similarly (46 vs. 62%; P<0.001; interaction P=0.25). After adjustment for clinical differences, CS on admission was an independent predictor of in-hospital mortality (P=0.008). CONCLUSION CS on admission patients have a worse outcome but benefit equally from emergency revascularization as delayed CS patients, emphasizing the need for rapid and direct access of CS on admission patients to facilities providing this care.

Abstract
Cardiogenic shock, a devastating consequence of acute myocardial infarction, is associated with extremely high mortality. Treatment strategies should focus on prompt reperfusion and hemodynamic support. The primary approach for therapy is emergent angiography and revascularization using percutaneous coronary intervention or coronary artery bypass surgery, with the assistance of intra-aortic balloon pump counterpulsation. Several adjunctive pharmacologic agents, particularly inotropic drugs and vasopressors, are also helpful for hemodynamic support. However, these agents have not been shown to provide a survival benefit, and their use is primarily based on clinical experience. Since our last publication, several important advances have been made in the understanding and treatment of cardiogenic shock. Recent evidence suggests that a systemic inflammatory response, including the upregulation of inducible nitric oxide synthase, complement activation, and an inflammatory cytokine cascade, play a role in the development of cardiogenic shock. Newer therapeutic strategies, including C5 inhibitors and nitric oxide synthase inhibitors, are being combined with traditional strategies, such as inotropic agents, vasopressors, and circulatory assist, to treat cardiogenic shock.

Abstract
We investigated the association between race/ethnicity on the use of cardiac resources in patients who have acute myocardial infarction that is complicated by cardiogenic shock. The Should We Emergently Revascularize Occluded Coronaries for Cardiogenic Shock (SHOCK) trial examined the effect of reperfusion and revascularization treatment strategies on mortality. Patients screened but not enrolled in the SHOCK Trial (n = 1,189) were entered into the SHOCK registry. Of the patients in the United States registry (n = 538) who had shock due to predominant left ventricular failure, 440 were characterized as white (82%), 42 as Hispanic (8%), 34 as African-American (6%), and 22 as Asian/other (4%). The use of invasive procedures differed significantly by race/ethnicity. Hispanic patients underwent coronary angiography significantly less often than did white patients (38 vs 66%, p = 0.002). Among those patients who underwent coronary angiography, there were no race/ethnicity differences in the proportion of patients who underwent revascularization (p = 0.353). Overall in-hospital mortality (57%) differed significantly by race/ethnicity (p = 0.05), with the highest mortality rate in Hispanic patients (74% vs 65% for African-Americans, 56% for whites, and 41% for Asian/other). After adjustment for patient characteristics and use of revascularization, there were no mortality differences by race/ethnicity (p = 0.262), with all race/ethnicity subgroups benefiting equally by revascularization. In conclusion, the SHOCK registry showed significant differences in the treatment and in-hospital mortality of Hispanic patients who had cardiogenic shock, with these patients being less likely to undergo percutaneous coronary intervention. Therefore, early revascularization should be strongly considered for all patients, independent of race/ethnicity, who develop cardiogenic shock after acute myocardial infarction.

Abstract
OBJECTIVE Left ventricular assist device (LVAD) insertion after anterior wall myocardial infarction complicated by cardiogenic shock is an accepted modality of support in select patients. Results of primary revascularization for these patients are poor. We seek to determine the outcomes of patients with myocardial infarction and shock who undergo LVAD insertion alone versus surgical revascularization before LVAD insertion. METHODS Seventy-four patients at 2 institutions underwent LVAD implantation for myocardial infarction and shock over a 12-year period. Twenty-eight underwent direct LVAD placement, and 46 underwent revascularization through coronary artery bypass grafting before LVAD placement. Variables examined included patient demographics, myocardial infarction-LVAD interval, bridge to transplantation, early mortality (< or = 30 days), survival after LVAD placement, and posttransplantation survivals. RESULTS There were no differences in demographics between the 2 groups. The group undergoing revascularization before LVAD placement had a lower bridge to transplantation, higher early mortality, and lower overall 6- and 12-month survivals after LVAD placement compared with the group undergoing direct LVAD placement (45.50% vs 70.40%, P = .041; 39.10% vs 14.30%, P = .020; 89.3% and 82.1% vs 54.4% and 52.2%, respectively, P = .006). Posttransplantation survival and LVAD explantation rates were equivalent in both groups. CONCLUSIONS Coronary artery bypass grafting before LVAD insertion for cardiogenic shock complicating myocardial infarction adversely affects survival. Confirmation of these findings would require conducting a large, multicenter, randomized clinical trial comparing revascularization versus LVAD support as primary therapy in this setting.

Abstract
Although percutaneous coronary intervention (PCI) in the setting of cardiogenic shock has a high in-hospital mortality rate, it has been shown to decrease the mortality rate in certain subgroups. The identity and relative importance of variables that are predictive of in-hospital mortality rate after PCI for cardiogenic shock are uncertain. Accordingly, we examined data of >300,000 patients in the American College of Cardiology-National Cardiovascular Data Registry (ACC-NCDR) that were collected from 1998 to 2002 and evaluated the outcomes in 483 consecutive patients who underwent emergency PCI for cardiogenic shock. Patients' mean age was 65 +/- 13 years, with men predominating (61%). All underwent emergency/salvage PCI in the setting of cardiogenic shock after acute myocardial infarction. Mean left ventricular ejection fraction was 30 +/- 16%. Stents were placed in 64% of patients, and thrombolytic agents were administered in 26%. Although PCI was angiographically successful in 79% of patients, the in-hospital mortality rate was 59.4%. Length of stay after PCI was 7.2 +/- 8 days. Logistic regression using all available variables identified 6 multivariate predictors of death: age (odds ratio [OR] 2.34, 95% confidence interval [CI] 1.68 to 3.28, p <0.001) for each 10-year increment, female gender (OR 1.55, 95% CI 1.00 to 2.41, p <0.001), baseline renal insufficiency (creatinine >2.0 mg/dl; OR 4.69, 95% CI 1.96 to 11.23, p <0.001), total occlusion in the left anterior descending artery (OR 1.99, 95% confidence interval 1.28 to 3.09, p <0.01), no stent used (OR 2.55, 95% CI 1.63 to 3.96, p <0.01), and no glycoprotein IIb/IIIa inhibitor used during PCI (OR 1.96, 95% CI 1.30 to 2.98, p <0.01). In a second analysis using only variables known to the clinician at the time of initial presentation, gender, age, renal insufficiency, and total occlusion of the left anterior descending coronary artery were significant. In conclusion, analysis of patients from the ACC-NCDR who underwent emergency PCI for acute myocardial infarction in the presence of cardiogenic shock shows an in-hospital mortality rate of approximately 60% when PCI is attempted.

Abstract
OBJECTIVES To determine predictors of outcome after percutaneous coronary intervention (PCI) in patients with cardiogenic shock complicating acute myocardial infarction. METHODS Retrospective analysis of a cohort of 113 patients undergoing emergency coronary angiography and attempted PCI for cardiogenic shock complicating acute myocardial infarction in a regional cardiothoracic unit. RESULTS In-hospital mortality was 51% (58 patients). Adverse outcome was associated with previous myocardial infarction, age over 70 years, cardiogenic shock complicating failure to respond to thrombolytic treatment (failed thrombolysis), and multivessel coronary artery disease. Multivariate logistic regression analysis showed that the first three factors were independent predictors of in-hospital death with odds ratios of 5.21 (95% confidence interval (CI) 1.85 to 14.69), 4.02 (95% CI 1.14 to 14.12), and 3.78 (95% CI 1.43 to 9.96), respectively. CONCLUSION About 50% of patients with cardiogenic shock undergoing a strategy of urgent coronary angiography and PCI survive to hospital discharge. Survivors do well in the subsequent six months. Emergency PCI for cardiogenic shock reduces mortality from an expected 80% to about 50%. Clinical features can help determine which patients are most likely to gain from urgent coronary angiography and attempted PCI. Alternative strategies are needed to improve the outcome of patients who fare badly.

Abstract
This retrospective observational review compares patient characteristics and in-hospital and long-term outcomes of cohorts of patients undergoing percutaneous coronary intervention (PCI) for cardiogenic shock complicating acute myocardial infarction (MI) prior to the use of stents (as well as glycoprotein IIb/IIIa inhibitor and dual-antiplatelet therapy) with PCI in the stent era. Cardiogenic shock remains the leading cause of hospital mortality from acute MI. This is a report of consecutive patients with cardiogenic shock complicating acute MI, without mechanical complication, referred for emergency catheterization to a single operator at two consecutive Veterans Affairs medical centers over a 15-year period (1988 to August 2003). PCI was attempted in all 93 cases: 44 consecutive patients in the present era and 49 consecutive patients in the stent era. Patients with comparable extent of coronary disease, more ST elevation myocardial infarction, multiple areas of infarction, and greater comorbidity underwent PCI in the stent era. Nevertheless, PCI in the stent era was associated with higher rates of acute success and improved in-hospital survival. Kaplan-Meier curves and log-rank testing showed highly significant improvement in overall survival (P < 0.0001). Logistic regression of in-hospital survival demonstrated that stent use (colinear with glycoprotein IIb/IIIa use and dual-antiplatelet therapy) was significantly associated with survival in a model adjusting for extent of coronary disease and comorbidities (P = 0.007). Stents and abciximab have been associated with improved acute angiographic and procedural success of PCI for cardiogenic shock, leading to improved survival.

Abstract
OBJECTIVE This study evaluates the influence of early revascularization (with percutaneous transluminal coronary angioplasty (PTCA) and coronary surgery) on short- and long-term survival in patients with cardiogenic shock complicating acute myocardial infarction (AMI). METHODS AND RESULTS In-hospital and 6-month survival were retrospectively determined on day 193 (65-270, median +/- 25th and 75th percentiles) in 87 patients who either underwent early invasive reperfusion (group A, n=60) or those who were treated conservatively (group B, n=27). In-hospital mortality was 37% in group A and 56% in group B (P=0.192). Six-month mortality was statistically lower in group A than in group B (30 patients (50%) compared with 25 patients (93%), P=0.005). Being a woman and older age were found to be factors increasing mortality. Lower mortality in the long term was strongly associated with revascularization (odds ratio=0.08, 95% confidence interval=1.54-109). PTCA was found to be an independent predictor of long-term survival (odds ratio= 0.22, 95% confidence interval=0.049-1.00, P=0.050), by multiple logistic regression. CONCLUSIONS In conclusion, this study suggests that early revascularization improves long-term survival of patients with cardiogenic shock complicating AMI, even after adjustment for baseline differences between patients who underwent early revascularization and those who did not.

Abstract
We sought to evaluate myocardial reperfusion and its prognostic value after percutaneous transluminal coronary angioplasty (PTCA) in patients admitted for cardiogenic shock. Lack of myocardial reperfusion despite restored coronary flow affects the survival of patients with acute myocardial infarction (AMI). Myocardial blush grade (MBG) is an angiographic measure of myocardial perfusion. We assessed MBG in 41 consecutive patients admitted to our department within 12 hours from the onset of AMI and in cardiogenic shock. PTCA was successful in 83% of patients. Thrombolysis In Mycardial Infarction (TIMI) grade 3 flow was demonstrated in 22 patients (53%). MBG 2/3 was found in 14 patients (34%); among them, 12 had TIMI 3 flow. Compared with patients with MBG 2/3, those with MBG 0/1 were older (71 +/- 11 vs 57 +/- 13 years, p = 0.001), had a higher prevalence of diabetes (48% vs 14%, p = 0.04) and hypertension (63% vs 29%, p = 0.04), showed a trend toward longer ischemic time (6.1 +/- 2.4 vs 4.9 +/- 1.1), and had larger enzymatic infarct size (peak creatine kinase 7,690 +/- 3,516 vs 5,500 +/- 2,977 IU/L). Mortality was higher in patients with MBG 0/1 both in the hospital (81% vs 14%, p <0.001) and at follow-up (81% vs 29%, p = 0.001). After adjustment by multivariate analysis, MBG 0/1 (odds ratio 16, p = 0.01) and age (odds ratio 3.8/10 years, p = 0.04) were correlated with in-hospital mortality. MBG 2/3 was achieved in a few patients in cardiogenic shock after AMI who were treated with PTCA; this was a strong predictor of in-hospital survival. Also, risk stratification after mechanical revascularization should include assessment of restoration of myocardial reperfusion.

Abstract
OBJECTIVE To describe the characteristics and mortality rates of 132 cardiogenic shock patients treated with intra-aortic balloon counterpulsation at a university hospital. INTERVENTIONS All patients underwent intra-aortic balloon counterpulsation. A total of 99 out of 132 patients were revascularized with angioplasty, surgery or were transplanted (intervention group), 33 out of 132 had no further intervention (no-intervention group). MEASUREMENTS AND RESULTS Overall mortality was 54.5% (72/132). In the intervention group mortality was 50.5% (50/99), in the no-intervention group mortality was 66.6% (22/33). The odds ratio for death comparing the intervention group with the no-intervention group was 0.533 (95% confidence interval 0.238-1.189, P = 0.122). By univariate analysis, diabetes and a left ventricular ejection fraction of less than 0.35 represented an increased odds ratio of death of 4.25 (1.813-9.965, P = 0.001) and 3.03 (1.22-7.54, P = 0.015), respectively. A lactate level greater than 2.5 mg/dl at baseline resulted in an increased odds ratio of death of 5.185 (1.988-13.525, P = 0.0001). Using a multivariate logistic regression analysis, a left ventricular ejection fraction less than 0.35 and diabetes remained significantly correlated with death. CONCLUSION Mortality rates remain high in cardiogenic shock patients in need of intra-aortic balloon counterpulsation. The odds ratio for death tended to be lower in the intervention group compared with the no-intervention group, although the absolute difference in mortality as a result of an intervention was only 15.2%, and did not reach statistical significance probably because of the small sample size. Diabetes and an ejection fraction lower than 35% are significant predictors for a worse prognosis.

Abstract
OBJECTIVE The objective of this study is to assess the feasibility and safety of interhospital transfer (within up to 60 minutes) for primary/rescue coronary angioplasty of patients with myocardial infarction (AMI) complicated by an early onset of acute heart failure (AHF) admitted to a community hospital without PCI facilities. DESIGN AND PATIENTS From the multicenter randomized PRAGUE-1 study, a subgroup of 66 patients with AMI complicated by AHF on the first presentation to the community hospital were retrospectively analyzed. Group A patients (n = 21) were treated on site in community hospitals using thrombolysis (streptokinase), group B patients (n = 20) were transported with thrombolytic infusion to a PCI center for coronary angioplasty, and group C patients (n = 25) were immediately transported to a PCI center for primary angioplasty without thrombolysis. RESULTS No patient died during transportation. One group B patient developed ventricular fibrillation during transfer. The time delay from the onset of chest pain to reperfusion was > 142 minutes, and 253 and 251 minutes in groups A, B, and C, respectively. Hospital stay (16 vs 11 vs 10 days, P = NS) was shorter in the angioplasty groups. Transported patients (groups B, C) displayed a significant decrease in heart failure progression within the first 24 hours after treatment (48% vs 15% vs 8%, P < 0.05). The combined end point, i.e., mortality + nonfatal reinfarction (43% vs 25% vs 8%, P < 0.05), was significantly less frequent in the coronary angioplasty group. CONCLUSIONS Interhospital transfer for coronary angioplasty of patients with AMI complicated by an early onset of AHF is feasible and safe. Transport for angioplasty may even reduce the risk of heart failure progression and improve clinical outcome compared to immediate thrombolysis in the nearest community hospital.

Abstract
BACKGROUND In patients with acute myocardial infarction (MI), the efficacy of thrombolysis is low. Angioplasty after failed thrombolysis (rescue percutaneous coronary angioplasty [PTCA]) has been associated with an increase in the incidence of inhospital complications. It has been proposed that these complications result from the procedure itself. Thus, the aim of this study was to compare the efficacy, inhospital complications, and mortality rate of patients with MI who are treated with primary PTCA and PTCA after initial thrombolysis (rescue or immediate rescue) in an experienced clinical center specializing in percutaneous coronary interventions. METHODS AND RESULTS The study group consisted of consecutive patients with MI treated with primary PTCA (n = 195) or PTCA after initial thrombolysis (n = 179). The study was performed in a referral center with a 24-hour catheter-laboratory service. The success rate of the procedure was 90.5% and 88.2% in the PTCA after initial thrombolysis group and primary PTCA group, respectively. The groups did not differ in the frequency of reocclusion, emergency surgical revascularization (coronary artery bypass grafting), or stroke. In patients without cardiogenic shock, the inhospital mortality rates were 3.2% and 0.6% in the rescue and immediate rescue group and primary PTCA group, respectively (not significant). In a subgroup of patients with cardiogenic shock, the mortality rate was 36.0% in the initial thrombolysis PTCA group and 30.8% in the primary PTCA group. However, after successful PTCA in this subgroup, the mortality rate dropped to 18% and 10%, respectively. CONCLUSIONS After initial thrombolysis, PTCA is safe, effective, and likely to restore grade 3 Thrombolysis In Myocardial Infarction flow in about 90% of patients. When available, immediate rescue PTCA should be performed in all patients, including patients with cardiogenic shock.

Abstract
BACKGROUND Several predictors of survival have been described in selected subgroups of patients suffering from acute myocardial infarction. However, data on unselected patients with acute myocardial infarction and cardiogenic shock, including patients with out-of hospital cardiac arrest, are missing. We aimed to assess predictors of survival for an unselected cohort of patients representative of clinical practice who experienced acute myocardial infarction and required continuous catecholamine support for circulatory failure. METHODS The study was performed at a 2000 bed university hospital. All consecutive patients admitted to our emergency department with acute myocardial infarction were prospectively enrolled in a clinical trial from 1993 to 2000. DESIGN A retrospective cohort study was performed on patients with myocardial infarction requiring catecholamine support within the first 24 h. Primary endpoint was in-hospital mortality. RESULTS The analysis was carried out on 262 patients, 189 men (72%), median age 65 years (IQR 53-73). Out-of-hospital cardiac arrest was reported in 47% (122/262). In-hospital mortality was 53% (138/262). Survivors as compared to non-survivors exhibited significant differences with respect to age (60 vs. 68 years, P<0.0001), systolic and diastolic blood pressure on admission (110 vs. 102 mmHg, P=0.01 and 64 vs. 58 mmHg, P=0.006, respectively), initial blood serum lactate (6.8 vs. 8.3, P=0.01), peak CKMB level (93 vs. 138 U/l, P=0.005), use of adrenaline (epinephrine) (38 vs. 68%, P<0.0001) and any attempt of revascularisation (76 vs. 63%, P=0.03). In a multivariate model younger age [OR 1.06 (CI 1.03-1.10), P<0.001], no use of adrenaline [OR 2.63 (CI 1.35-5.26) P=0.005] and lower peak CKMB [OR 1.01 (CI 1.01-1.01), P<0.0001] were independently associated with in-hospital survival. CONCLUSION In unselected patients including CPR survivors with acute myocardial infarction requiring continuous catecholamine support, younger age, the absence of continuous adrenaline administration and a lower peak CKMB were independently associated with increased in-hospital survival.

Abstract
Patients with ST-segment elevation acute myocardial infarction require immediate reperfusion therapy. Reperfusion therapy can be provided by either pharmacologic or mechanical means. Pharmacologic reperfusion therapy consists of administering fibrinolytics, whereas mechanical reperfusion consists of performing percutaneous intervention, usually with stent placement. Each approach has been shown to decrease mortality, but each has disadvantages in establishing flow in the infarct-related artery. Regardless of the approach, during an acute myocardial infarction, activation and externalization of glycoprotein (GP) IIb-IIIa receptors occur on the surface of platelets. The GP IIb-IIIa inhibitors block the binding of fibrinogen to these platelet receptors. These inhibitors have been investigated in combination with both reperfusion strategies. The goal of adding GP IIb-IIIa inhibitor therapy to either reperfusion approach is to obtain better early, complete, and sustained reperfusion. Subsequently, this should lead to better clinical outcomes for patients with ST-segment elevation acute myocardial infarction. Although no mortality benefit has been seen with the addition of GP IIb-IIIa inhibitor therapy, ischemic complications have been reduced significantly.
