Application of European Society of Cardiology guidelines for evaluating acute coronary syndrome risk in low-risk patients with cocaine-associated chest pain: Findings from the RISK study - An observational analysis. Toxicol Rep 2024; 13:101680. [PMID: 39006369 PMCID: PMC11245997 DOI: 10.1016/j.toxrep.2024.05.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 05/24/2024] [Accepted: 05/25/2024] [Indexed: 07/16/2024] Open
Abstract
Background Cocaine was the drug of choice in 4.7 % of all recreational drug-related emergency department visits. Of these patients, 40 % present with cocaine-associated chest pain, of whom 4.7 % develop an acute coronary syndrome. The American Heart Association recommends a 12-hour observation period for these patients. Objective This study primarily aimed to ascertain whether the European Society of Cardiology non-ST-elevation myocardial infarction guidelines can be safely applied to rule-out acute coronary syndrome in low-risk patients with cocaine-associated chest pain. Methods For this prospective observational cohort study, patients, aged 18-45 years old, who presented with cocaine-associated chest pain and were risk stratified as low risk according to the European Society of Cardiology non-ST-elevation myocardial infarction guidelines and therefore discharged home without prolonged observation period, were included. They were followed to assess major adverse cardiac events four weeks after presentation to the emergency department or chest pain unit. Cocaine use was confirmed with urine toxicology screening. Results A total of 107 patients were included and analysed. The accuracy of the self-reported history of recent cocaine use was 94 %. Post-discharge cocaine use persisted among 32 % of patients. None of the included 107 patients died and major adverse cardiac event within four weeks did not occur among 97 patients with available data regarding MACE. Conclusion Ruling out an acute coronary syndrome using the European Society of Cardiology non-ST-elevation myocardial infarction guidelines is likely to be safe for patients with cocaine-associated chest pain, however this study was underpowered to reach definitive conclusions.

Abstract
Cocaine is one of the most commonly abused drugs and represents a major public health concern. Cocaine users frequently present to the emergency department, with chest pain being the most common presenting complaint. The incidence of acute myocardial infarction in patients with cocaine-associated chest pain is often quoted as 6%, but it is highly variable depending on the included population. Risk assessment can be challenging in these patients; serial assessment of electrocardiograms and troponins is often required. This review focuses on the assessment and management of patients presenting with cocaine-associated chest pain and cardiotoxicity. Specific treatments are discussed, including benzodiazepines, nitroglycerin, calcium channel blockers, and phentolamine, and how treatment priorities differ from patients with noncocaine presentations. The use of beta-blockers in this population remains controversial, and the literature around its use is reviewed. The most recent literature and recommendations for the use of percutaneous coronary intervention and fibrinolytics in cocaine-associated myocardial infarction is discussed as well. Cocaine-associated dysrhythmias are suggested to be the cause of sudden cardiac death in some users. The pathophysiology and evidence-based treatments for dysrhythmias are reviewed. This review provides evidence-based recommendations for the assessment and management of patients presenting with cocaine-associated cardiovascular toxicity.

Prevalence of myocardial infarction among patients with chest pain and cocaine use: A systematic review and meta-analysis. Am J Emerg Med 2021; 50:428-436.

Abstract
BACKGROUND Cocaine abuse is a public health burden. Cocaine is known to cause vasospasm and acute myocardial infarction (AMI). The prevalence of AMI in patients presenting with chest pain and concurrent cocaine use (CPCC) varies among studies. We performed a systemic review and meta-analysis to assess the current literature for the prevalence of AMI in patients with CPCC. METHODS We performed a literature search of PubMed, EMBASE, and Scopus from its beginning to May 18, 2020 and updated this search on February 18, 2021. Full-text studies that assessed the primary outcome (AMI) specifically among patients with CPCC who presented to the emergency department (ED) were included. We excluded studies that were not in English, did not take place in the ED, and case reports, which only reported positive cases and not incidence of AMI. Random effect meta-analysis was performed to assess the prevalence of primary outcome and to examine correlations between risk factors and AMI. Heterogeneity was assessed by I-square value. We also performed subgroup analysis to identify potential sources of heterogeneity. RESULTS We identified 2178 studies and screened 102 full-text studies to include 16 studies (3269 patients) in our final analysis. The pooled prevalence of AMI was 4.7% (95% CI 0.8-23), I-square of 84%. However, rates among studies of low risk patients were lower (1.1% 95% CI 0.2-5) compared to studies of mixed risk patients (7.7%, 95% 5-11). A meta-regression was used to look at correlation between risk factors and AMI and found that AMI was positively correlated in patients with a history of CAD (correlation coefficient [Corr. Coeff.] 5.6, 96% CI 2.3-8.7), HTN (Corr. Coeff. 2.9, 95% CI 0.9-4.9), DM (Corr. Coeff. 8.0, 95% CI 2.4-14), HLD (Corr. Coeff. 5.9, 95% CI 2.4, 9). Sources of potential heterogeneity included patients' risk as defined by the authors, study designs, publication year, and study sample size. CONCLUSION The overall prevalence of AMI and death among patients with cocaine-associated chest pain was relatively low, although high risk patients were still associated with high prevalence of AMI. Clinicians should consider risk-stratify these patients and treat them accordingly.

Abstract
INTRODUCTION Cocaine is considered a cardiovascular risk factor, yet it is not included in the frequently used risk stratification scores. Moreover, many guidelines provide limited advice on how to diagnose and treat cocaine-associated chest pain (CACP). This study aimed to determine the current practice for CACP patients in emergency departments and coronary care units throughout the Netherlands. METHODS An anonymous online questionnaire-based survey was conducted among Dutch emergency physicians and cardiologists between July 2015 and February 2016. The questionnaire was based on the American Heart Association CACP treatment algorithm. RESULTS A total of 214 subjects were enrolled and completed the questionnaire. All responders considered cocaine use a risk factor for developing acute coronary syndrome (ACS), nevertheless 74.4 % of emergency physicians and 81.1 % of cardiologists do not always question chest pain patients about drug use. Of all responders, 73.6 % never perform toxicology screening. Most responders (60 %) observe patients with CACP according to the European Society of Cardiology ACS guideline, and 24.3 % give these patients ß-blockers. CONCLUSION The current practice for CACP patients in most emergency departments and coronary care units in the Netherlands is not in line with the AHA scientific statement. Emergency physicians and cardiologists should be advised to routinely question all chest pain patients on drug history and be aware that the risk stratifications scores are not validated for CACP. Despite the AHA scientific statement of 2008, many respondents utilize ß-blockers for CACP patients, which is supported by published evidence since the statement appeared.

Abstract
INTRODUCTION HEART score is widely used to stratify patients with chest pain in the emergency department but has never been validated for cocaine-associated chest pain (CACP). We sought to evaluate the performance of HEART score in risk stratifying patients with CACP compared to an age- and sex-matched cohort with non-CACP. METHODS The parent study was an observational cohort study that enrolled consecutive patients with chest pain. We identified patients with CACP and age/sex matched them to patients with non-CACP in 1:2 fashion. HEART score was calculated retrospectively from charts. The primary outcome was major adverse cardiac events (MACE) within 30 days of indexed encounter. RESULTS We included 156 patients with CACP and 312 age-and sex-matched patients with non-CACP (n = 468, mean age 51 ± 9, 22% females). There was no difference in rate of MACE between the groups (17.9% vs. 15.7%, p = 0.54). Compared to the non-CACP group, the HEART score had lower classification performance in those with CACP (AUC = 0.68 [0.56-0.80] vs. 0.84 [0.78-0.90], p = 0.022). In CACP group, Troponin score had the highest discriminatory value (AUC = 0.72 [0.60-0.85]) and Risk factors score had the lowest (AUC = 0.47 [0.34-0.59]). In patients deemed low-risk by the HEART score, those with CACP were more likely to experience MACE (14% vs. 4%, OR = 3.7 [1.3-10.7], p = 0.016). CONCLUSION In patients with CACP, HEART score performs poorly in stratifying risk and is not recommended as a rule out tool to identify those at low risk of MACE.

Abstract
OBJECTIVE Current guidelines recommend treating patients with cocaine-associated chest pain, unstable angina, or myocardial infarction similarly to patients with traditional acute coronary syndrome (ACS). Risk stratifying these patients could potentially reduce unnecessary procedures and improve resource utilization. METHODS This is a retrospective cross-sectional analysis of 258 patients presenting with cocaine-associated ACS who underwent cardiac catheterization in a community teaching hospital between 2006 and 2015. The primary outcome was the prevalence of acute obstructive coronary artery disease (CAD) requiring percutaneous coronary intervention and coronary artery bypass grafting compared with that of patients with normal coronary or nonobstructive disease. RESULTS Of the studied population, 36% had obstructive CAD requiring intervention and 64% were found to have normal coronaries or nonobstructive disease. Significant risk factors for obstructive CAD were older age, history of CAD, diabetes mellitus, dyslipidemia, ST-segment-elevation myocardial infarction, and troponin elevation. A logistic model was developed based on these variables, applied to the studied population, and was found to have 93% sensitivity in predicting the likelihood of obstructive CAD. CONCLUSIONS Cardiac catheterization in patients presenting with cocaine-associated ACS may be overutilized. A predictive model based on clinical risk factors may help individualize patient care and reduce unnecessary invasive diagnostic interventions.

Abstract
BACKGROUND The outcomes related to chest pain associated with cocaine use and its burden on the healthcare system are not well studied. METHODS Data were collected from the Nationwide Inpatient Sample (2001-2012). Subjects were identified by using the International Classification of Diseases, Ninth Revision, Clinical Modification codes. Primary outcome was a composite of mortality, myocardial infarction, stroke, and cardiac arrest. RESULTS We identified 363,143 admissions for cocaine-induced chest pain. Mean age was 44.9 (±21.1) years with male predominance. Left heart catheterizations were performed in 6.7%, whereas the frequency of acute myocardial infarction and percutaneous coronary interventions were 0.69% and 0.22%, respectively. The in-hospital mortality was 0.09%, and the primary outcome occurred in 1.19% of patients. Statistically significant predictors of primary outcome included female sex (odds ratio [OR], 1.16; confidence interval [CI], 1.00-1.35; P = .046), age >50 years (OR, 1.24, CI, 1.07-1.43; P = .004), history of heart failure (OR, 1.63, CI, 1.37-1.93; P <.001), supraventricular tachycardia (OR, 2.94, CI, 1.34-6.42; P = .007), endocarditis (OR, 3.5, CI, 1.50-8.18, P = .004), tobacco use (OR, 1.3, CI, 1.13-1.49; P <.001), dyslipidemia (OR, 1.5, CI, 1.29-1.77; P <.001), coronary artery disease (OR, 2.37, CI, 2.03-2.76; P <.001), and renal failure (OR, 1.27, CI, 1.08-1.50; P = .005). The total annual projected economic burden ranged from $155 to $226 million with a cumulative accruement of more than $2 billion over a decade. CONCLUSION Hospital admissions due to chest pain and concomitant cocaine use are associated with low rates of adverse outcomes. For the low-risk cohort in whom acute coronary syndrome has been ruled out, hospitalization may not be beneficial and may result in unnecessary cardiac procedures.

Abstract
With each successive year, the number of Emergency Department (ED) visits related to illicit drug abuse has progressively increased. Cocaine is the most common illegal drug to cause a visit to the ED. Cocaine use results in a variety of pathophysiological changes with regards to the cardiovascular system, such as constriction of coronary vessels, dysfunction of vascular endothelium, decreased aortic elasticity, hemodynamic disruptions, a hypercoagulable state, and direct toxicity to myocardial and vascular tissue. The clinical course of patients with cocaine-induced chest pain (CCP) is often challenging, and electrocardiographic findings can be potentially misleading in terms of diagnosing a myocardial infarction. In addition, there is no current satisfactory study regarding outcomes of use of various pharmacological drug therapies to manage CCP. At present, calcium-channel blockers and nitroglycerin are two pharmacological agents that are advocated as first-line drugs for CCP management, although the role of labetalol has been controversial and warrants further investigation. We performed an extensive search of available literature through a large number of scholarly articles previously published and listed on Index Medicus. In this review, we put forward a concise summary of the current approach to a patient presenting to the ED with CCP and management of the clinical scenario. The purpose of this review is to summarize the understanding of cocaine's cardiovascular pathophysiology and to examine the current approach for proper evaluation and management of CCP.

Clinical Profile, Acute Care, and Middle-Term Outcomes of Cocaine-Associated ST-Segment Elevation Myocardial Infarction in an Inner-City Community. Am J Cardiol 2016; 117:1224-30. [PMID: 26897639 DOI: 10.1016/j.amjcard.2016.01.019] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2015] [Revised: 01/18/2016] [Accepted: 01/18/2016] [Indexed: 10/22/2022]
Abstract
Although cocaine is a well-recognized risk factor for coronary disease, detailed information is lacking regarding related behavioral and clinical features of cocaine-associated ST-segment elevation myocardial infarction (STEMI), particularly in socioeconomically disadvantaged urban settings. Nor are systematic or extended follow-up data available on outcomes for cocaine-associated STEMI in the contemporary era of percutaneous coronary intervention. We leveraged a prospective STEMI registry from a large health system serving an inner-city community to characterize the clinical features, acute management, and middle-term outcomes of cocaine-related versus cocaine-unrelated STEMI. Of the 1,003 patients included, 60% were black or Hispanic. Compared with cocaine-unrelated STEMI, cocaine-related STEMI (n = 58) was associated with younger age, male gender, lower socioeconomic score, current smoking, high alcohol consumption, and human immunodeficiency virus seropositivity but less commonly with diabetes or hypertension. Cocaine users less often received drug-eluting stents or β blockers at discharge. During median follow-up of 2.7 years, rates of death, death or any rehospitalization, and death or cardiovascular rehospitalization did not differ significantly between cocaine users and nonusers but were especially high for death or any hospitalization in the 2 groups (31.4 vs 32.4 per 100 person-years, p = 0.887). Adjusted hazard ratios for outcomes were likewise not significantly different. In conclusion, in this low-income community, cocaine use occurred in a substantial fraction of STEMI cases, who were younger than their nonuser counterparts but had more prevalent high-risk habits and exhibited similarly high rates of adverse outcomes. These data suggest that programs targeting cocaine abuse and related behaviors could contribute importantly to disease prevention in disadvantaged communities.

Abstract
Introduction In 2007 there were 64,000 visits to the emergency department (ED) for possible myocardial infarction (MI) related to cocaine use. Prior studies have demonstrated that low- to intermediate-risk patients with cocaine-associated chest pain can be safely discharged after 9–12 hours of observation. The goal of this study was to determine the safety of an 8-hour protocol for ruling out MI in patients who presented with cocaine-associated chest pain. Methods We conducted a retrospective review of patients treated with an 8-hour cocaine chest pain protocol between May 1, 2011 and November 30, 2012 who were sent to the clinical decision unit (CDU) for observation. The protocol included serial cardiac biomarker testing with Troponin-T, CK-MB (including delta CK-MB), and total CK at 0, 2, 4, and 8 hours after presentation with cardiac monitoring for the observation period. Patients were followed up for adverse cardiac events or death within 30 days of discharge. Results There were 111 admissions to the CDU for cocaine chest pain during the study period. One patient had a delta CK-MB of 1.6 ng/ml, but had negative Troponin-T at all time points. No patient had a positive Troponin-T or CK-MB at 0, 2, 4 or 8 hours, and there were no MIs or deaths within 30 days of discharge. Most patients were discharged home (103) and there were 8 inpatient admissions from the CDU. Of the admitted patients, 2 had additional stress tests that were negative, 1 had additional cardiac biomarkers that were negative, and all 8 patients were discharged home. The estimated risk of missing MI using our protocol is, with 99% confidence, less than 5.1% and with 95% confidence, less than 3.6% (99% CI, 0–5.1%; 95% CI, 0–3.6%). Conclusion Application of an abbreviated cardiac enzyme protocol resulted in the safe and rapid discharge of patients presenting to the ED with cocaine-associated chest pain.

Abstract
INTRODUCTION AND OBJECTIVES To investigate the relationship between the prevalence of cocaine use disorders and acute myocardial infarction in patients aged ≥ 18 years and to estimate the influence of cocaine use disorders on mortality, excess length of stay, and overexpenditure among hospitalized patients with acute myocardial infarction. METHODS Retrospective study of the minimum basic data set of 87 Spanish hospitals from 2008 to 2010. RESULTS Among 5 575 325 admissions reviewed, there were 24 126 patients with cocaine use disorders and 79 076 cases of acute myocardial infarction. The incidence of acute myocardial infarction among patients with cocaine use disorders increased with age and reached a peak at 55 years to 64 years (P < .0001). Multivariate analysis showed that cocaine use disorders were more prevalent among patients with acute myocardial infarction independently of age, sex, other addictive disorders, and 30 other comorbidities (odds ratio = 3.0). Among patients with acute myocardial infarction, those with cocaine use disorders did not show an increase of in-hospital death, but did show excess length of hospital stay (1.5 days) and overexpenditure (382 euros). CONCLUSIONS Cocaine use disorders are associated with acute myocardial infarction and increase the length of hospital stay and overexpenditure among acute myocardial infarction patients. Cessation of cocaine use among these patients should be one of the primary therapeutic goals after hospital discharge.

Abstract
BACKGROUND Emergency departments may be a useful information source to describe the demographics and clinical characteristics of patients with acute cocaine-related medical problems. We therefore conducted a retrospective analysis of 165 acute, laboratory-confirmed cocaine intoxications admitted to an urban emergency department in Switzerland between January 2007 and March 2011. RESULTS A total of 165 patients with a mean age of 32 years were included. Most patients were male (73%) and unemployed (65%). Only a minority (16%) had abused cocaine alone while 84% of the patients had used at least one additional substance, most commonly ethanol (41%), opioids (38%), or cannabis (36%) as confirmed by their detection in blood samples. The most frequently reported symptoms were chest pain (21%), palpitations (19%), anxiety (36%) and restlessness (36%). Psychiatric symptoms were present in 64%. Hypertension and tachycardia were observed in 53% and 44% of the patients, respectively. Severe poisonings only occurred in patients with multiple substance intoxication (15%). Severe intoxications were non-significantly more frequent with injected drug use compared to nasal, oral, or inhalational drug use. Severe complications included acute myocardial infarction (2 cases), stroke (one case), and seizures (3 cases). Most patients (75%) were discharged home within 24 h after admission. A psychiatric evaluation in the ED was performed in 24% of the patients and 19% were referred to a psychiatric clinic. CONCLUSIONS Patients with acute cocaine intoxication often used cocaine together with ethanol and opioids and presented with sympathomimetic toxicity and/or psychiatric disorders. Severe acute toxicity was more frequent with multiple substance use. Toxicity was typically short-lasting but psychiatric evaluation and referral was often needed.

Abstract
The ECG is a rapidly available clinical tool that can help clinicians manage poisoned patients. Specific myocardial effects of cardiotoxic drugs have well-described electrocardiographic manifestations. In the practice of clinical toxicology, classic ECG changes may hint at blockade of ion channels, alterations of adrenergic tone, or dysfunctional metabolic activity of the myocardium. This review will offer a structured approach to ECG interpretation in poisoned patients with a focus on clinical implications and ECG-based management recommendations in the initial evaluation of patients with acute cardiotoxicity.

Abstract
Heart failure requiring urgent therapy represents a burgeoning health care burden. Although acute heart failure syndromes are commonly defined as a change in chronic heart failure signs and symptoms requiring urgent therapy, the presentation, development, and response to treatment is highly dependent on individual patient characteristics. This heterogeneity has led to challenges in interpreting widely differing study methods, including eligibility requirements and outcome measures. To improve interpretation of results and translate such information to better patient care, it is essential to present an accurate description of the patient population and study design. Based on existing recommendations and expert consensus, the authors present standardized reporting criteria to improve interpretability of research in this challenging cohort.

Abstract
BACKGROUND Few trials have examined the outcomes of patients who use cocaine with chest pain and who have a normal or nondiagnostic electrocardiogram (ECG) and the use of single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI). HYPOTHESIS We sought to compare the characteristics and overall outcomes in cocaine users vs non-cocaine users presenting to the emergency department with a normal/nondiagnostic ECG and to assess the value of rest MPI in both of these populations. METHODS Patients with symptoms compatible with myocardial ischemia, suspected acute coronary syndrome (ACS), and a normal/nondiagnostic ECG were enrolled in the Emergency Room Assessment of Sestamibi for Evaluation of Chest Pain (ERASE Chest Pain) trial, a randomized controlled trial designed to evaluate the impact of rest MPI on triage decisions. Cocaine users (n = 294) were compared to non-cocaine users (n = 2180). Cocaine users were younger than non-cocaine users, and 72% were male. RESULTS Among the cocaine users, 2.4% had a myocardial infarction, 1.4% required percutaneous coronary intervention, and none of the patients underwent coronary artery bypass graft surgery. Among cocaine users with a final diagnosis of not ACS, randomization of patients to rest SPECT MPI resulted in an appropriate reduction in hospital admissions in both the cocaine users (P = 0.011) and the non-cocaine users (P < 0.001), suggesting improved triage when MPI was used. CONCLUSIONS Cocaine users with a normal/nondiagnostic ECG are at low risk of cardiac events. Even though cocaine users are at low risk of cardiac events, SPECT MPI remains effective in the risk stratification and improves triage management decisions resulting in lower admission rates and more discharges to home.

Abstract
The authors present a case of a 65-year-old male who presented four times to the emergency department (ED) with left-sided chest pain. On the first three visits, the patient was admitted with a different diagnosis related to his chest pain. On the final visit, an abnormality on an imaging study performed in the ED led to the ultimate diagnostic test revealing the cause of the patient's symptoms. The patient's clinical presentation and ultimate clinical course are summarized, and a discussion of the differential diagnoses of his condition is presented.

Abstract
Every year more than 500,000 patients present to the emergency department with cocaine-associated complications, most commonly chest pain. Many of these patients undergo extensive work-up and treatment. Much of the evidence regarding cocaine's cardiovascular effects, as well as the current management of cocaine-associated chest pain and acute coronary syndromes, is anecdotally derived and based on studies written more than 2 decades ago that involved only a few patients. Newer studies have brought into question many of the commonly held theories and practices regarding the etiology, diagnosis, and treatment of this common clinical scenario. However, there continues to be a paucity of prospective, randomized trials addressing this topic as it relates to clinical outcomes. We searched PubMed for English-language articles from 1960 to 2011 using the keywords cocaine, chest pain, coronary arteries, myocardial infarction, emergency department, cardiac biomarkers, electrocardiogram, coronary computed tomography, observation unit, β-blockers, benzodiazepines, nitroglycerin, calcium channel blockers, phentolamine, and cardiomyopathy; including various combinations of these terms. We reviewed the abstracts to confirm relevance, and then full articles were extracted. References from extracted articles were also reviewed for relevant articles. In this review, we critically evaluate the limited historical evidence underlying the current teachings on cocaine's cardiovascular effects and management of cocaine-associated chest pain. We aim to update the reader on more recent, albeit small, studies on the emergency department evaluation and clinical and pharmacologic management of cocaine-associated chest pain. Finally, we summarize recent guidelines and review an algorithm based on the current best evidence.

Abstract
Background Cocaine induced chest pain is a major reason for admission in Safety Net Hospitals in the United States. The majority of patients admitted undergo extensive work-up leading to enormous economic burden. We hypothesize that in individuals with low risk, cocaine does not further increase adverse cardiovascular outcomes. Methods We conducted a retrospective chart review of all patients admitted with chest pain to our hospital between 07/01/09 and 06/30/10. We excluded patients with modifiable risk factors for coronary artery disease (CAD). The study population was divided into cocaine and non-cocaine group based on urine drug screen. We analyzed data including demographic, laboratory, cardiac testing, detection of CAD, length of stay and mortality rates. Results A total of 426 individuals matched our inclusion and exclusion criteria and were considered to have no known modifiable cardiac risk factors; 54 in cocaine group and 372 in non-cocaine group. Based on physician discretion, 41(76%) in the cocaine group and 239(64%) in the non-cocaine group underwent various modalities of cardiac testing. Cardiac testing was positive in 6(2.5%) patients in non-cocaine group and none in the cocaine group (p=0.597). There was no significant difference between length of stay and in-hospital mortality between the two groups. Conclusions In individuals at low risk for CAD, cocaine use resulted in higher rate of cardiac testing. However, there is no difference in prevalence of CAD and in-hospital mortality between the two groups. We conclude that cocaine does not increase adverse outcomes in patients with low risk for CAD.

Abstract
The decision to admit a patient to the hospital after an emergency department (ED) visit is expensive, frequently not evidence-based, and variable. Outpatient critical pathways are a promising approach to reduce hospital admission after emergency care. Critical pathways exist to risk stratify patients for potentially serious diagnoses (e.g., acute myocardial infarction [AMI]) or evaluate response to therapy (e.g., community-acquired pneumonia) within a short time period (i.e., less than 36 hours), to determine if further hospital-based acute care is needed. Yet, such pathways are variably used while many patients are admitted for conditions for which they could be treated as outpatients. In this article, the authors propose a model of post-ED critical pathways, describe their role in emergency care, list common diagnoses that are amenable to critical pathways in the outpatient setting, and propose a research agenda to address barriers and solutions to increase the use of outpatient critical pathways. If emergency providers are to routinely conduct rapid evaluations in outpatient or observation settings, they must have several conditions at their disposal: 1) evidence-based tools to accurately risk stratify patients for protocolized care, 2) systems of care that reliably facilitate workup in the outpatient setting, and 3) a medical environment conducive to noninpatient pathways, with aligned risks and incentives among patients, providers, and payers. Increased use of critical pathways after emergency care is a potential way to improve the value of emergency care.

Abstract
OBJECTIVES Observational studies of patients with cocaine-associated myocardial infarction have suggested more coronary disease than expected on the basis of patient age. The study objective was to determine whether cocaine use is associated with coronary disease in low- to intermediate-risk emergency department (ED) patients with potential acute coronary syndrome (ACS). METHODS The authors conducted a cross-sectional study of low- to intermediate-risk patients<60 years of age who received coronary computerized tomographic angiography (CTA) for evaluation of coronary artery disease (CAD) in the ED. Patients were classified into three groups with respect to CAD: maximal stenosis <25%, 25% to 49%, and ≥50%. Prespecified multivariate modeling (generalized estimating equations) was used to assess relationship between cocaine and CAD. RESULTS Of 912 enrolled patients, 157 (17%) used cocaine. A total of 231 patients had CAD ≥25%; 111 had CAD ≥50%. In univariate analysis, cocaine use was not associated with a lesion 25% or greater (12% vs. 14%; relative risk [RR]=0.89, 95% confidence interval [CI]=0.5 to 1.4) or 50% or greater (12% vs. 11%; RR=1.15, 95% CI=0.6 to 2.3). In multivariate modeling adjusting for age, race, sex, cardiac risk factors, and Thrombosis in Myocardial Infarction (TIMI) score, cocaine use was not associated with the presence of any coronary lesion (adjusted RR=0.95, 95% CI=0.69 to 1.31) or coronary lesions 50% or greater (adjusted RR=0.78, 95% CI=0.45 to 1.38). There was also no relationship between repetitive cocaine use and coronary calcifications or between recent cocaine use and CAD. CONCLUSIONS In symptomatic ED patients at low to intermediate risk of an ACS, cocaine use was not associated with an increased likelihood of coronary disease after adjustment for age, race, sex, and other risk factors for coronary disease.

Abstract
INTRODUCTION Chest pain suggestive of myocardial ischemia or infarction is a common emergency department complaint and a subset of these is associated with cocaine use. It can be difficult to triage patients with chest pain while using cocaine. OBJECTIVE To assess the reliability of the initial electrocardiogram (ECG) done in the emergency department in current cocaine users suspected of acute coronary syndrome (ACS) in predicting a true event. METHODS A total of 218 charts of current cocaine users who presented with chest pain judged as possibly cardiac in nature with an initial ECG from September 2003 to August 2007 were reviewed. Initial ECG was classified into: (1) Category A (inverted T waves in two or more contiguous leads and/or characteristic ST segment elevation or depression indicative of an ischemic event possibly acute); (2) Category B (other ischemic changes but without any ST or T abnormalities such as Q wave, or bundle branch block); or (3) Category C (normal tracing, non-specific ST segment or T wave alterations). RESULTS Eighteen of 218 (8.3%) were confirmed to have ACS. Ten of 18 confirmed ACS patients were among the 70 cases with ECG classified as Category A. One hundred and one of 218 were Category C ECGs: five of these had ACS (three of the five had significant cardiac history) and 96 did not, consistent with 95% negative predictive value. Patients with Category A ECG characteristics were three times at risk to have ACS compared with a Category C ECG. CONCLUSION The initial ECG with a good clinical history can be used effectively to triage patients presenting with chest pain and current use of cocaine in the emergency department.

Abstract
The management of low-risk patients presenting to emergency departments is a common and challenging clinical problem entailing 8 million emergency department visits annually. Although a majority of these patients do not have a life-threatening condition, the clinician must distinguish between those who require urgent treatment of a serious problem and those with more benign entities who do not require admission. Inadvertent discharge of patients with acute coronary syndrome from the emergency department is associated with increased mortality and liability, whereas inappropriate admission of patients without serious disease is neither indicated nor cost-effective. Clinical judgment and basic clinical tools (history, physical examination, and electrocardiogram) remain primary in meeting this challenge and affording early identification of low-risk patients with chest pain. Additionally, established and newer diagnostic methods have extended clinicians' diagnostic capacity in this setting. Low-risk patients presenting with chest pain are increasingly managed in chest pain units in which accelerated diagnostic protocols are performed, comprising serial electrocardiograms and cardiac injury markers to exclude acute coronary syndrome. Patients with negative findings usually complete the accelerated diagnostic protocol with a confirmatory test to exclude ischemia. This is typically an exercise treadmill test or a cardiac imaging study if the exercise treadmill test is not applicable. Rest myocardial perfusion imaging has assumed an important role in this setting. Computed tomography coronary angiography has also shown promise in this setting. A negative accelerated diagnostic protocol evaluation allows discharge, whereas patients with positive findings are admitted. This approach has been found to be safe, accurate, and cost-effective in low-risk patients presenting with chest pain.

Abstract
INTRODUCTION AND OBJECTIVES To investigate the frequency of recent cocaine use in patients attending an emergency department for acute chest pain, to describe the clinical characteristics of these patients, and to estimate the incidence of acute coronary syndrome in this population. METHODS Observational cohort study using a standard questionnaire that includes items on recent cocaine consumption. RESULTS During a 1-year period, 1240 patients aged under 55 years presented with chest pain. Of these, 63 (5%) had cocaine-related chest pain (7% of men and 1.8% of women). These patients were younger (35+/-10 years vs. 39+/-10 years; P=.002), were more frequently male (87% vs. 62%; P< .001), and were more frequently smokers (59% vs. 35%; P< .001). Patients who had used cocaine recently had a higher incidence of acute myocardial infarction (16 vs. 4%; P< .001), especially ST-segment-elevation myocardial infarction (11.1% vs. 1.6%; P< .01). After adjusting for coronary risk factors, history of cardiovascular disease and previous treatment, the odds ratio for myocardial infarction with recent cocaine consumption was 4.3 (95% confidence interval, 2-9.4). CONCLUSIONS Cocaine-related chest pain is often encountered in emergency departments, especially in men aged under 55 years. It is associated with a four-fold increase in the risk of acute myocardial infarction. All male patients aged under 55 years with acute chest pain should be asked about cocaine use.

Abstract
BACKGROUND Most patients presenting to emergency departments (EDs) with cocaine-associated chest pain are admitted for at least 12 hours and receive a "rule out acute coronary syndrome" protocol, often with noninvasive testing prior to discharge. In patients without cocaine use, coronary computerized tomography angiography (CTA) has been shown to be useful for identifying a group of patients at low risk for cardiac events who can be safely discharged. It is unclear whether a coronary CTA strategy would be efficacious in cocaine-associated chest pain, as coronary vasospasm may account for some of the ischemia. We studied whether a negative coronary CTA in patients with cocaine-associated chest pain could identify a subset safe for discharge. METHODS We prospectively evaluated the safety of coronary CTA for low-risk patients who presented to the ED with cocaineassociated chest pain (self-reported or positive urine test). Consecutive patients received either immediate coronary CTA in the ED (without serial markers) or underwent coronary CTA after a brief observation period with serial cardiac marker measurements. Patients with negative coronary CTA (maximal stenosis less than 50%) were discharged. The main outcome was 30-day cardiovascular death or myocardial infarction. RESULTS A total of 59 patients with cocaine-associated chest pain were evaluated. Patients had a mean age of 45.6 +/- 6.6 yrs and were 86% black, 66% male. Seventy-nine percent had a normal or nonspecific ECG and 85% had a TIMI score <2. Twenty patients received coronary CTA immediately in the ED, 18 of whom were discharged following CTA (90%). Thirty-nine received coronary CTA after a brief observation period, with 37 discharged home following CTA (95%). Six patients had coronary stenosis >or=50%. During the 30-day follow-up period, no patients died of a cardiovascular event (0%; 95% CI, 0-6.1%) and no patient sustained a nonfatal myocardial infarction (0%; 95% CI, 0-6.1%). CONCLUSIONS Although cocaine-associated myocardial ischemia can result from coronary vasoconstriction, patients with cocaine associated chest pain, a non-ischemic ECG, and a TIMI risk score <2 may be safely discharged from the ED after a negative coronary CTA with a low risk of 30-day adverse events.

Abstract
Cocaine use has been associated with a significant risk of myocardial ischemia and myocardial infarction (MI). The previous approach to the treatment of cocaine-induced MI focused on medical treatment with verapamil, nitroglycerine and thrombolytics. Percutaneous revascularization for the cocaine-associated MI has been reported and is the preferred treatment modality. Identification of culprit vessel in the patients presenting with acute myocardial infarction associated with cocaine use is problematic owing to the frequent presence of baseline electrocardiogram (ECG) changes. Chronic cocaine use predisposes to diffuse coronary vasculopathy and may cause systemic alteration of coagulation parameters. Multivessel coronary thrombosis presenting as myocardial infarction associated with cocaine use has not been previously reported. This study describes a case of multivessel coronary thrombosis caused by cocaine ingestion successfully treated with multivessel primary angioplasty.
