Exogenous adenosine triphosphate disodium administration during primary percutaneous coronary intervention reduces no-reflow and preserves left ventricular function in patients with acute anterior myocardial infarction: a study using myocardial contrast echocardiography. Int J Cardiol 2008; 140:200-9. [PMID: 19081151 DOI: 10.1016/j.ijcard.2008.11.041] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2008] [Revised: 09/21/2008] [Accepted: 11/08/2008] [Indexed: 11/19/2022]
Abstract
BACKGROUND It is unknown whether adenosine triphosphate disodium (ATP) administration during primary percutaneous coronary intervention (PCI) is useful in anterior acute myocardial infarction (AMI). METHODS The study was a prospective, non-randomized, open-label trial. Primary PCI was successfully performed in 204 consecutive patients with first anterior AMI. ATP at a mean dose of 117 microg/kg/min for 45 min on an average was infused intravenously during PCI in 100 patients (Group 1). In the other 104 patients, normal saline was administered (Group 2). ST-segment resolution (STR) was estimated 90 min after recanalization. The no-reflow ratio was measured 2 weeks later, using intravenous myocardial contrast echocardiography. Left ventricular ejection fraction (LVEF), LV regional wall motion (LVRWM), and LV end-diastolic volume index (LVEDVI) were measured 6 months later. RESULTS Baseline patient characteristics of the two groups were similar, including TIMI risk scores. Significant STR (> or =50% resolution compared to baseline) (66% versus 50%; Group 1 versus Group 2, p=0.02), no-reflow ratio (24% versus 34%, indicated by mean values, p=0.02), LVEF (61% versus 55%, p=0.0007), LVRWM (-1.56 versus -2.05, using the SD/chord, p=0.0001), and LVEDVI (60 ml/m(2) versus 71 ml/m(2), p=0.0007) were significantly better in Group 1, and the no-reflow ratio, LVEF, LVRWM and LVEDVI were significantly better in ATP-administered patients, regardless of antecedent angina or advanced age. ATP Administration was consistently identified as a significant determinant for STR, no-reflow ratio, LVEF, LVRWM, and LVEDVI. CONCLUSIONS Intravenous ATP administration during reperfusion is an independent determinant of STR and the no-reflow ratio, and LVEF, LVRWM, and LVEDVI at 6 months after primary PCI.

Abstract
BACKGROUND Quantifying adherence to quality indicators can serve as a direct measure of quality of care and provide the foundation for quality improvement. However, quality indicators for percutaneous coronary intervention (PCI) have not been developed in Canada. OBJECTIVE To develop a set of quality and outcome indicators for PCI that can be used across Canada. METHODS A 12-member national expert panel was selected to represent practice in different regions of Canada. Potential quality indicators were identified by a detailed search of published guidelines, randomized trials and outcomes studies. A two-step modified Delphi process was employed with an initial screening round of indicator ratings, followed by a national quality indicator panel meeting, and follow-up discussions to obtain consensus. RESULTS A total of 26 indicators including six structure indicators, nine process indicators, and 11 outcomes indicators were identified by the national expert panel to be representative of high quality of care for PCI. Pharmacological indicators included prescription of acetylsalicylic acid, clopidogrel and statin therapy as adjunctive therapy for PCI. Nonpharmacological process indicators included minimal procedure volumes, door-to-balloon time in primary PCI, prevention of contrast-induced nephropathy and selected patient education counselling instructions. Outcome indicators included death, myocardial infarction, target vessel revascularization and vascular access complications after PCI. CONCLUSIONS A new set of PCI quality indicators for use in the Canadian health care system was developed. The widespread adoption and implementation of PCI quality indicators in clinical practice will facilitate the identification of practice gaps to enable quality improvement efforts and to optimize the outcomes of patients undergoing PCI throughout Canada.

Abstract
BACKGROUND An invasive approach of acute myocardial infarction with ST-segment elevation (STEMI) with primary percutaneous coronary intervention (PCI) is currently considered as the most efficient revascularisation strategy and is performed around-the-clock in tertiary hospitals. The present study is aimed at investigating the short term outcome of primary PCI eligible patients after STEMI in a regional institution (CHCV, Sion) in comparison to a University Hospital (CHUV, Lausanne). METHODS From January the 1st to December the 31st 2002, all consecutive STEMI patients of both centres who had an emergency coronary arteriography were included in the analysis. Clinical and angiographic data were retrospectively collected. The primary end point was the combined incidence of in-hospital death, reinfarction, and target vessel revascularisation (TVR) at 7 days. RESULTS The analysis included 58 patients in the CHVC (60+/-13 years, 16% of whom were female) and 160 patients in the CHUV (63+/-12 years, 25% were female). Both populations were identical according to the severity of coronary artery disease and distribution of risk factors, except for smokers (55% in CHCV, 39% CHUV, p=0.04). Most of the patients were treated by PCI in both centres (80% CHCV versus 86% CHUV, p=NS). A low proportion in both groups underwent urgent surgical treatment (3.5% CHCV versus 5.5% CHUV, p=NS). At 7 days, adverse events free survival was not statistically different. CONCLUSION These results were expected because the CHCV fulfils the international guidelines criteria for performance of emergency angioplasty. Our study demonstrates that around-the-clock primary PCI for acute STEMI can safely be done in a regional hospital (CHCV Sion) providing there is strict adherence to all aspects of international guidelines.

Abstract
BACKGROUND The Stent or Surgery Trial is a randomized, controlled trial comparing percutaneous coronary intervention with coronary artery bypass grafting (CABG) for patients with multivessel disease. Initial results at a median follow-up of 2 years showed a survival advantage for patients randomized to CABG. This article reports survival outcome at a median follow-up of 6 years. METHODS AND RESULTS A total of 988 (n=488 percutaneous coronary intervention, n=500 CABG) patients were randomized at 53 centers during the period from 1996 to 1999. Investigators established survival status from hospital or community medical records or national databases or by direct contact with patients and their relatives. All-cause mortality was compared with hazard ratios and confidence intervals calculated from Cox proportional hazards models. Prespecified subgroup analyses for diabetes mellitus, angina grade, and angiographic severity of coronary disease at baseline were performed with tests for interaction. At a median follow-up of 6 years, 53 patients (10.9%) died in the percutaneous coronary intervention group compared with 34 (6.8%) in the CABG group (hazard ratio 1.66, 95% confidence interval 1.08 to 2.55, P=0.022). Little evidence was found that the treatment effect on mortality differed between subgroups according to baseline angina grade (interaction test P=0.52), the severity of coronary disease (P=0.92), or diabetic status (P=0.15). CONCLUSIONS At a median follow-up of 6 years, a continuing survival advantage was observed for patients managed with CABG, which is not consistent with results from other stent-versus-CABG studies.

Abstract
INTRODUCTION Current European clinical guidelines do not restrict interventional cardiology at centers without on-site surgical backup, but disagreement still exists whether hospitals with cardiac catheterization laboratories, but without on-site cardiac surgery, should develop percutaneous coronary intervention (PCI) programs. Technical improvements in equipment and pharmacologic adjunctive therapy have increased the safety margins of diagnostic and therapeutic cardiac catheterization and more than half of the patients treated by PCI in Portugal are treated at hospitals without on-site cardiac surgery. OBJECTIVES We set out to compare clinical outcomes of elective and primary PCI for ST-segment elevation myocardial infarction at centers without on-site cardiac surgery with those at centers with on-site cardiac surgery. METHODS Based on the Portuguese Registry of Interventional Cardiology, we retrospectively reviewed a total of 13,235 PCI procedures performed from January 2002 to June 2006 and compared the results for 7,112 patients treated at hospitals without on-site cardiac surgery with 6,123 patients treated at hospitals with on-site cardiac surgery. RESULTS Demographic data were similar, with a mean age of 64 (55-72) vs. 63 (54-71) years, 75% vs. 76% male and 25.0% vs. 24.2% with diabetes respectively at centers without and with on-site surgical backup. Hospital mortality at centers without and with on-site surgical backup respectively was: chronic angina: 0.3% vs. 0.3% (NS); acute coronary syndromes: 1.5% vs. 1.0% (NS); acute myocardial infarction with ST elevation and without cardiogenic shock: 4.0% vs. 5.0% (NS); cardiogenic shock: 50.9% vs. 53.4% (NS). CONCLUSIONS Similar clinical outcomes for interventional cardiology were achieved at hospitals without on-site cardiac surgery and those with on-site cardiac surgery. In the era of coronary stents, adjunctive therapy and experienced operators, elective and primary PCI can safely be performed without on-site surgical backup.

Abstract
BACKGROUND Despite proven advantages of primary percutaneous coronary intervention (PCI), thrombolysis remains the first line treatment for ST-elevation myocardial infarction (STEMI) worldwide. Management of patients with failed thrombolysis is still debated, and data from existing randomized controlled trials are conflicting. AIM To compare the risk/benefit profile of repeat thrombolysis (RT) vs. rescue PCI in patients with failed thrombolysis. METHODS Search of BioMedCentral, CENTRAL, mRCT and PubMed for randomized controlled trials comparing rescue PCI vs. conservative therapy and/or RT vs. conservative therapy. Outcomes of interest assessed by adjusted indirect meta-analysis: major adverse events (MAE, defined as the composite of overall mortality and re-infarction), stroke, congestive heart failure (CHF), major bleeds (MB), and minor bleeds. Overall mortality and re-infarction have been also analysed individually. RESULTS Eight trials were included (1318 patients). Follow-up ranged from 'in-hospital' to 6 months. No significant difference was found for the risk of MAE [OR 0.93(0.26-3.35), P = 0.4], overall mortality [OR 1.01(0.52-1.95), P = 0.15], stroke [OR 5.03(0.64-39.1), P = 0.58] and CHF [OR 0.74(0.28-1.96), P = 0.6]. Compared with conservative therapy, rescue PCI was associated with a 70% reduction in the risk of re-infarction [OR 0.32(0.14-0.74), P = 0.008], number needed to treat 17. No difference in terms of MB was found [OR 0.5(0.1-2.5), P = 0.09], while a greater risk of minor bleeds was observed with rescue PCI [OR 2.48(1.08-5.7), P = 0.04], number needed to harm 50. CONCLUSION Although the observed benefit is modest, these data support the use of PCI after failed thrombolysis.

Abstract
OBJECTIVE To use funnel plots and cumulative funnel plots to compare in-hospital outcome data for operators undertaking percutaneous coronary interventions with predicted results derived from a validated risk score to allow for early detection of variation in performance. DESIGN Analysis of prospectively collected data. SETTING Tertiary centre NHS hospital in the north east of England. PARTICIPANTS Five cardiologists carrying out percutaneous coronary interventions between January 2003 and December 2006. MAIN OUTCOME MEASURES In-hospital major adverse cardiovascular and cerebrovascular events (in-hospital death, Q wave myocardial infarction, emergency coronary artery bypass graft surgery, and cerebrovascular accident) analysed against the logistic north west quality improvement programme predicted risk, for each operator. Results are displayed as funnel plots summarising overall performance for each operator and cumulative funnel plots for an individual operator's performance on a case series basis. RESULTS The funnel plots for 5198 patients undergoing percutaneous coronary interventions showed an average observed rate for major adverse cardiovascular and cerebrovascular events of 1.96% overall. This was below the predicted risk of 2.06% by the logistic north west quality improvement programme risk score. Rates of in-hospital major adverse cardiovascular and cerebrovascular events for all operators were within the 3sigma upper control limit of 2.75% and 2sigma upper warning limit of 2.49%. CONCLUSION The overall in-hospital major adverse cardiovascular and cerebrovascular events rates were under the predicted event rate. In-hospital rates after percutaneous coronary intervention procedure can be monitored successfully using funnel and cumulative funnel plots with 3sigma control limits to display and publish each operator's outcomes. The upper warning limit (2sigma control limit) could be used for internal monitoring. The main advantage of these charts is their transparency, as they show observed and predicted events separately. By this approach individual operators can monitor their own performance, using the predicted risk for their patients but in a way that is compatible with benchmarking to colleagues, encapsulated by the funnel plot. This methodology is applicable regardless of variations in individual operator case volume and case mix.

Abstract
INTRODUCTION The Danish Heart Registry (DHR) keeps track of all coronary angiographies (CATH), percutaneous coronary interventions (PCI), coronary artery bypass grafting (CABG), and adult heart valve surgery performed in Denmark. DHR is a clinical database established in order to follow the activity and quality of the procedures mentioned. MATERIALS AND METHODS Information concerning each procedure, age, gender, and co-morbidity of the patient was collected. Each patient was followed with respect to survival for 30 days by linkage to the central personal registry in Denmark. Mortality was estimated by the Kaplan-Meier method and comparisons of 30-day mortality between centres were carried out in Cox proportional hazard models. RESULTS The mortality within 30 days after PCI was 3.2% and closely related to the indication for PCI: ST-elevation myocardial infarction (STEMI) 6.8%; non-STEMI & unstable angina pectoris 1.9% and stable angina pectoris 0.5%. The 30-day mortality after PCI on the indication STEMI did not differ between the five centres, P=0.30. Mortality within 30 days after isolated CABG was 2.6% and was closely related to the EuroSCORE. The 30-day mortality after isolated CABG did not differ between the five centres, P=0.12. CONCLUSION The 30-day mortality was closely related to the indication for PCI and the EuroSCORE for patients undergoing CABG. There were no significant differences in 30-day mortality between centres after either primary PCI or isolated CABG.

Abstract
AIM To describe: a/ the improvement in quality of life (QoL) among patients on the waiting list for coronary revascularisation and b/ the association between QoL and very long-term mortality. PATIENTS All patients on the waiting list for possible coronary revascularisation in western Sweden during one week in September 1990. METHODS QoL was assessed at the start of the survey and one year later among patients who both were and were not revascularised. Survival data were gathered for the subsequent 14 years. RESULTS From the start, 883 patients were evaluated in the survey. Among patients who were revascularised, an improvement was seen in all the aspects of QoL that were studied during the first year as compared with patients who were not revascularised, in whom only minor changes in QoL were seen during the first year. After one year, there were seven aspects of QoL which were significantly associated with the risk of death during the subsequent 14 years, when adjusting for age, sex, previous history and extent of coronary artery disease. They were: tiredness (OR=1.4), weakness (OR=1.5), lack of energy (OR=1.5), inability to react (OR=1.7), use of sedatives (OR=3.2), dyspnea when dressing (OR=2.1) and chest pain when dressing (OR=1.9). CONCLUSION Among patients on the waiting list for possible coronary revascularisation, there was a marked improvement in QoL among those who were revascularised. In a variety of aspects of QoL, an association with the very long-term risk of death was observed.

Abstract
BACKGROUND If primary percutaneous coronary intervention (PCI) is performed promptly, the procedure is superior to fibrinolysis in restoring flow to the infarct-related artery in patients with ST-segment elevation myocardial infarction. The benchmark for a timely PCI intervention has become a door-to-balloon time of less than 90 minutes. Whether regional strategies can be developed to achieve this goal is uncertain. METHODS We developed an integrated-metropolitan-area approach in which all patients with ST-segment elevation myocardial infarction were referred to a specialized center for primary PCI. We sought to determine whether there was a difference in door-to-balloon times between patients who were referred directly from the field by paramedics trained in the interpretation of electrocardiograms and patients who were referred by emergency department physicians. RESULTS Between May 1, 2005, and April 30, 2006, a total of 344 consecutive patients with ST-segment elevation myocardial infarction were referred for primary PCI: 135 directly from the field and 209 from emergency departments. Primary PCI was performed in 93.6% of patients. The median door-to-balloon time was shorter in patients referred from the field (69 minutes; interquartile range, 43 to 87) than in patients needing interhospital transfer (123 minutes; interquartile range, 101 to 153; P<0.001). Door-to-balloon times of less than 90 minutes were achieved in 79.7% of patients who were transferred from the field and in 11.9% of those transferred from emergency departments (P<0.001). CONCLUSIONS Guideline door-to-balloon-times were more often achieved when trained paramedics independently triaged and transported patients directly to a designated primary PCI center than when patients were referred from emergency departments.

For many patients with ST-segment elevation myocardial infarctions (STEMIs), the time from presentation to percutaneous coronary intervention exceeds established goals. This study was conducted to examine the effects of formalized data assessment and systematic feedback on treatment times. All patients with STEMIs treated with percutaneous coronary intervention in a semi-rural 3-hospital network from January 1, 2006, to December 31, 2006, were prospectively analyzed (n = 114). Patients presenting during the first 3-month period (January 1, 2006, to March 31, 2006) were included as the reference group (n = 33). Time points from initial contact with the medical system to revascularization were assessed, analyzed, and presented in an interactive session to hospital and emergency services staff members. Data from patients with STEMIs presenting during the next 3 quarters were presented in the same manner (n = 28, 25, and 28). The median contact-to-balloon time was 113 minutes in the reference quarter, decreasing to 83, 66, and 74 minutes in the intervention groups (p <0.0001), whereas the median door-to-balloon time decreased from 54 minutes in the reference group to 35, 31, and 26 minutes in the intervention groups (p <0.0001). The proportion of patients with contact-to-balloon times <90 minutes increased from 21% to 79% (p <0.0001). There were significant reductions in the durations of initial treatment on location and in the emergency room and in puncture-to-balloon-time in the catheterization laboratory, and more patients were transported directly to the catheterization laboratory, bypassing the emergency room (from 23% in the reference quarter to 76% in the last intervention quarter, p <0.0001). In conclusion, formalized data feedback leads to marked reduction in revascularization times in patients with STEMIs.

Abstract
Until now, the permission to set up a centre for percutaneous coronary intervention (PCI) has been governed by Dutch law to ensure the availability and quality of PCI procedures. Recently, the Minister of Health proposed abolishing this law for PCI procedures. The Dutch Society of Cardiology has issued stringent guidelines for PCI centres. Even small hospitals should be able to start a PCI programme by following these stringent guidelines.

Abstract
The Dutch Health Council report on 'Invasive cardiac procedures' [Bijzondere interventies aan her hart] recommends, for reasons of quality, efficiency and patient safety, that cardiac surgery, percutaneous coronary interventions, and the invasive treatment of cardiac rhythm disorders be concentrated in a limited number of fully equipped cardiac centres. Small hospitals should therefore not carry out invasive cardiac procedures.

Abstract
BACKGROUND The American Heart Association Get With the Guidelines-Coronary Artery Disease program facilitates patient and physician compliance with proven atherosclerosis risk reduction strategies with collaborative learning sessions, teaching materials, predischarge online check lists, and web-based performance measure feedback for continuous quality improvement. Patients having coronary artery bypass graft surgery (CABG) may be subject to different care processes, nursing unit pathways, and personnel than patients having percutaneous catheter intervention or neither intervention, which may affect compliance. METHODS AND RESULTS The Get With the Guidelines-Coronary Artery Disease database was queried to determine whether compliance with secondary prevention performance measures for CABG patients was different from that for nonsurgical patients. A total of 119,106 patients were treated with CABG (14,118), percutaneous catheter intervention (58,702), or neither intervention (46,286). Compliance with medication prescriptions, including aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, and lipid-lowering drugs, and smoking cessation counseling for eligible patients was analyzed. Medically appropriate exclusions and contraindications were included in the analysis. After adjusting for 14 clinical variables, CABG patients were less likely to receive most secondary prevention measures relative to percutaneous catheter intervention patients. In contrast, CABG patients were more likely to receive aspirin, beta-blocker, and smoking cessation counseling than neither intervention patients. Composite adherence and defect-free rates were highest for percutaneous catheter intervention patients and lowest for neither intervention patients after adjustment. CONCLUSIONS There are significant differences in compliance at hospital discharge with secondary prevention performance measures for CABG patients compared with nonsurgical patients. Process of care differences may explain these differences and should be examined further because significant opportunities for improved compliance are evident. CABG patients in particular represent a group for whom secondary prevention has proven benefits, and they may benefit from future quality improvement interventions.

Abstract
Background Primary Percutaneous Coronary Intervention (PCI) is more efficacious than thrombolysis in the management of acute myocardial infarction, but, because of the requirement for prompt treatment, there are practical challenges in developing such services. We examined the proportion of patients with ST segment Elevation Myocardial Infarction (STEMI) who could receive timely treatment from a primary Percutaneous Coronary Intervention (PCI) service assuming different geographical locations of potential treatment centres in three English counties. Methods and results Information on the residential location of patients with new STEMI hospitalisations recorded in Hospital Episodes Statistics was analysed and the proportion of episodes of STEMI within 60' and 45' travel time isochrones from potential primary PCI centres in three English counties was calculated. There were on average 1,815 new STEMI hospitalisations per year occurring in the studied population. Introduction of a primary PCI service in one, two or three potential treatment centres would have covered respectively 28%, 73% and 90% of such episodes within 60 minutes travel time, and 17%, 51% and 69% within 45 minutes travel time. Conclusion In the study context, a primary PCI service in an existing tertiary centre would only cover a minority of STEMI events and would generate geographical inequities. A two-centre model would improve coverage and equity considerably, but may be associated with practical, clinical quality and financial challenges.

Abstract
Background—
Quality improvement efforts have focused on strategies to improve the timeliness of reperfusion therapy in ST-elevation myocardial infarction patients who present to hospitals with and without percutaneous coronary intervention (PCI) capability. We implemented and evaluated a protocol to optimize the timeliness of reperfusion therapy and to coordinate systems of care for a PCI center and 28 regional hospitals located up to 150 miles away across 3 states.
Methods and Results—
The present study focused on a prospective, observational cohort of 597 patients who presented with ST-segment elevation and within 12 hours of symptom onset to Saint Marys Hospital and 28 regional hospitals up to 150 miles away between May 2004 and December 2006. The Mayo Clinic ST-elevation myocardial infarction protocol implemented strategies to improve timeliness of reperfusion therapy and to coordinate systems of care for transfer between hospitals. The study sample consisted of 258 patients who presented to Saint Marys Hospital and were treated with primary PCI (group A), 105 patients who presented to a regional hospital with symptom onset >3 hours and then were transferred for primary PCI (group B), and 131 patients who presented to a regional hospital with symptom onset <3 hours and were treated with full-dose fibrinolytic therapy (group C). For groups A and B, median door-to-balloon times were 71 and 116 minutes, respectively. Door-to-balloon time <90 minutes was achieved in 75% of group A and 12% of group B. Median door-to-needle time was 25 minutes for group C, and 70% had door-to-needle time <30 minutes.
Conclusions—
The Mayo Clinic ST-elevation myocardial infarction protocol demonstrates the feasibility of implementing strategies to optimize the timeliness of reperfusion therapy and the times that can be achieved through coordinated systems of care for ST-elevation myocardial infarction patients presenting to a PCI center (Saint Marys Hospital) and 28 regional hospitals without PCI capability located up to 150 miles away across 3 states.

Abstract
Background—
Percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) is superior to fibrinolysis when performed in a timely manner in high-volume centers. Recent European trials suggest that transfer for PCI also may be superior to fibrinolysis and increase access to PCI. In the United States, transfer times are consistently long; therefore, many believe a transfer for PCI strategy for STEMI is not practical.
Methods and Results—
We developed a standardized PCI-based treatment system for STEMI patients from 30 hospitals up to 210 miles from a PCI center. From March 2003 to November 2006, 1345 consecutive STEMI patients were treated, including 1048 patients transferred from non-PCI hospitals. The median first door-to-balloon time for patients <60 miles (zone 1) and 60 to 210 miles (zone 2) from the PCI center was 95 minutes (25th and 75th percentiles, 82 and 116 minutes) and 120 minutes (25th and 75th percentiles, 100 and 145 minutes), respectively. Despite the high-risk unselected patient population (cardiogenic shock, 12.3%; cardiac arrest, 10.8%; and elderly [≥80 years of age], 14.6%), in-hospital mortality was 4.2%, and median length of stay was 3 days.
Conclusions—
Rapid transfer of STEMI patients from community hospitals up to 210 miles from a PCI center is safe and feasible using a standardized protocol with an integrated transfer system.

Abstract
We developed a regional strategy to decrease the time to percutaneous coronary intervention (PCI) for patients with acute ST-segment elevation myocardial infarction (STEMI). Protocols were created for paramedics and referring hospitals to identify and directly triage all patients with STEMI to a single PCI center. Time to PCI reperfusion and in-hospital mortality were assessed in 233 consecutive patients with STEMI. Ninety-minute initial hospital door-to-patent infarct artery was achieved in 58.3% of paramedic-diagnosed and directly triaged patients compared with 37.5% of "walk-ins" to the PCI hospital and with only 5.2% of those transferred from another hospital emergency department (ED; p <0.001). Overall in-hospital mortality was 2.1%, 0% in paramedic identified patients, and 0% in those walk-ins to the PCI hospital ED compared with 4.3% for those transferred from a referring hospital ED (p = 0.007). Paramedic diagnosis of STEMI and direct triage to a prealerted interventional hospital for primary PCI was associated with a high percentage of patients achieving <90-minute infarct artery patency. Substantial delays remained for those who presented initially to a non-PCI hospital ED despite the expedited protocol. In conclusion, this observational study suggests that wider use of paramedic electrocardiographic STEMI diagnosis and direct triage to a prealerted PCI hospital catheterization team may help improve outcomes of patients with STEMI.

Abstract
Patients with diabetes and coronary artery disease are frequently considered for myocardial revascularization procedures, aiming at cardiovascular events risk reduction and a better quality of life. In clinical practice, decisions concerning surgery or percutaneous coronary intervention are frequently difficult, because of cases' severity, disease extension and co-morbidities association. Beyond that, the bulk of literature information was generated by subgroup analysis of randomized clinical trials, which were designed for the general population, not for diabetics. The aim of this study was to review literature on coronary percutaneous intervention in diabetic patients, and also to show recent data from the experience in this procedure at the Catheterization Laboratory of the Cardiology Institute of RS.

Abstract
Repeated radial artery puncture for cardiac catheterization. The radial artery approach for percutaneous cardiac interventions has gained worldwide acceptance due to the similar results obtained by the femoral artery access. In this paper, we report our experience with repeated puncture of the radial artery. One hundred and eighty two radial artery access procedures were performed, in 17 interventions the puncture was repeated once or twice, with a total of 20 therapeutic catheterizations (9 coronary angiographies, 11 angioplasties). There was no therapeutic failure through the radial approach but, we successfully gained access in 88.2% (15/17) of the re-interventions cases. Although an experience with a low number of cases, we had a very high successful therapeutic rate, and also a remarkable lowering of local complications, this shows the feasibility and potential of this technique.

Abstract
The European Society of Cardiology (ESC) for the first time issued guidelines for percutaneous coronary interventions (PCI) in spring 2005. The strengths of recommendations stated in the ESC guidelines (as in those of the AHA/ACC [American Heart Association/American College of Cardiology]) are traditionally a combination of recommendation classes (I, IIa, and IIb) and a level of evidence (A, B, or C). This paper explains and discusses selected focal points of the ESC PCI guidelines based on three representative cases from daily practice. 1. Stable coronary artery disease (CAD): PCI in a 53-year-old patient without angina pectoris and proof of myocardial ischemia. With a clear indication of ischemia in the anterior myocardial wall, the ESC PCI guidelines indicated coronary angiography with possible PCI, even without angina pectoris symptoms. Cardiac catheterization showed a 99% proximal LAD stenosis, which was immediately dilated and stented based on the indicated ischemia. According to the ESC PCI guidelines, an intervention is indicated for CAD when a larger ischemic area is clearly evident even in the absence of typical angina (recommendation class I A). 2. ST segment elevation myocardial infarction (STEMI): PCI even after successful thrombolysis. A 70-year-old patient experienced acute substernal pain and immediately went to his nearby hospital. The ECG clearly showed anterior myocardial wall STEMI, which in this hospital without a cardiac cath lab indicated thrombolysis, since it could be initiated within 3 h after the onset of chest pain. Pain relief was evident soon after thrombolysis, combined with a resolution of the ST segment elevations. As suggested by the ESC PCI guidelines, a transfer to a cardiac cath lab took place the next day, where the 50% residual stenosis of the LAD was stented. The ESC PCI guidelines suggest coronary angiography with possible PCI within 1-2 days following successful thrombolysis (recommendation class I A). Thus, even "successful" thrombolysis is not regarded as the final treatment for STEMI. 3. Premature termination of clopidogrel after stent implantation: stent thrombosis with acute myocardial infarction. A 46-year-old patient visited the practice due to increasing dyspnea. 4 months earlier, a Taxus stent had been implanted at a heart center into the second RPLS of the RCX; 3 days later, a Cypher stent was implanted in the LAD. Upon being discharged on a Friday at noon, the patient was advised to see his general practitioner soon to attain a prescription for clopidogrel. The patient was given an appointment at his general practitioner for the following Wednesday afternoon. But on that Wednesday morning the patient went into cardiogenic shock. Although the occluded LAD (stent thrombosis) could be quickly reopened, left ventricular myocardium became severely damaged. Until a cardiac transplantation will be performed, a defibrillator was implanted. This "organizational" gap in clopidogrel administration did not conform to the ESC PCI guidelines: after implantation of any coronary stent, dual antiplatelet treatment (acetylsalicylic acid and clopidogrel) must be consistently administered for at least 4 weeks. After implantation of drug-eluting stents (DES), the ESC PCI guidelines call for clopidogrel administration for at least 6 months; when small vessels, long lesions or a complex anatomy (e. g., bifurcation stenting) are involved, a duration of 1 year or even longer is recommended. The optimal duration of platelet aggregation inhibition following PCI with DES of unprotected left main stem stenoses is unknown at this time. The traditional levels of evidence according to ESC, AHA and ACC criteria (levels A, B, or C) do no longer meet the actual requirements to assess the scientific evidence of randomized PCI trials and registry studies. For example, only two small randomized studies with few patients and insufficient statistical power utilizing a clinically insignificant surrogate endpoint would be enough to attain level of evidence A. Consequently, a new scoring system will be proposed, which considers criteria such as the importance of a primary clinical endpoint, the statistical power achieved, and the presence of an independent external data review and safety monitoring board.

Abstract
BACKGROUND Prompt reperfusion treatment is essential for patients who have myocardial infarction with ST-segment elevation. Guidelines recommend that the interval between arrival at the hospital and intracoronary balloon inflation (door-to-balloon time) during primary percutaneous coronary intervention should be 90 minutes or less. However, few hospitals meet this objective. We sought to identify hospital strategies that were significantly associated with a faster door-to-balloon time. METHODS We surveyed 365 hospitals to determine whether each of 28 specific strategies was in use. We used hierarchical generalized linear models and data on patients from the Centers for Medicare and Medicaid Services to determine the association between hospital strategies and the door-to-balloon time. RESULTS In multivariate analysis, six strategies were significantly associated with a faster door-to-balloon time. These strategies included having emergency medicine physicians activate the catheterization laboratory (mean reduction in door-to-balloon time, 8.2 minutes), having a single call to a central page operator activate the laboratory (13.8 minutes), having the emergency department activate the catheterization laboratory while the patient is en route to the hospital (15.4 minutes), expecting staff to arrive in the catheterization laboratory within 20 minutes after being paged (vs. >30 minutes) (19.3 minutes), having an attending cardiologist always on site (14.6 minutes), and having staff in the emergency department and the catheterization laboratory use real-time data feedback (8.6 minutes). Despite the effectiveness of these strategies, only a minority of hospitals surveyed were using them. CONCLUSIONS Several specific hospital strategies are associated with a significant reduction in the door-to-balloon time in the management of myocardial infarction with ST-segment elevation.

Abstract
Improvement of care quality does not end with the publication of clinical trials that show clinical evidence of effectiveness or with its support by the different international therapeutic guides. This quality improvement requires evaluation in the real population. This can be done by analysis of clinical registries, that would evaluate adequate compliance of the clinical guides and their effectiveness in the real population. The CRUSADE study is a study that evaluates use, prognosis and factors of prediction, of invasive strategy by early percutaneous coronary intervention (PCI) (first 48 hours of the ischemic event) in high-risk patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS). Of the 17,926 patients studied, 8037 (44.8%) underwent cardiac catheterism in the first 48 hours of the ischemic event. Intrahospital mortality of the invasive strategy was significantly less than medical treatment (2.5% versus 3.7%). The patients who underwent an early invasive strategy were a selected population, as the more solid independent prediction factors were associated to early invasive treatment: cardiology care, earlier age, absence of renal failure, absence of heart failure both previously or on arrival to the hospital and lower heart rate. Finally, it could be concluded that, in spite of the decrease of mortality achieved with the early invasive strategy, this would not done in most of the patients, being reserved for subgroups with lower comorbidity and for those seen by the cardiologists.
