    INTRODUCTION: The prevalence and long-term consequences of differences in baseline cardiac geometry (as a result of hypertension) in patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) are ill-defined. The primary purpose of this study was to clarify whether there were differences among sexual and racial groups in echocardiographic findings reflecting cardiac geometry and adaptation in patients undergoing PCI for ACS and whether this could explain the differences in outcomes seen between these groups. MATERIAL AND METHODS: We analyzed 1-year follow-up data from a single institution, a retrospective, observational study that enrolled 1,153 patients who presented with ACS and were treated with PCI, for whom echocardiographic data were available. RESULTS: Normal, concentric hypertrophy, and eccentric hypertrophy in males vs. females were observed as follows: 29% vs. 19% ( CONCLUSIONS: Females undergoing PCI for ACS are at higher risk for worse outcomes because they are more likely to express the eccentric hypertrophy phenotype; however, it did not account for the difference in adverse outcomes observed between sexes

    INTRODUCTION: The accuracy of detecting myocardial infarction (MI) has greatly improved with the advent of more sensitive assays, and this has led to etiologic subtyping. Distinguishing between type 1 and type 2 non-ST-segment elevation myocardial infarction (NSTEMI) early in the clinical course allows for the most appropriate advanced diagnostic procedures and most efficacious treatments. The purpose of this study was to investigate the predictive effect of demographic and clinical variables on predicting NSTEMI subtypes in patients presenting with ischemic symptoms. MATERIAL AND METHODS: We performed a single institution retrospective cohort study of patients who presented to the emergency department (ED) with ischemic signs and symptoms consistent with non-ST-segment myocardial infarction, for whom results of coronary angiography were available. We analyzed demographic, laboratory, echocardiography and angiography data to determine predictors of NSTEMI sub-types. RESULTS: Five hundred and forty-six patients were enrolled; 426 patients were found on coronary angiography to have type 1 acute MI (T1AMI), whereas 120 patients had type 2 acute MI (T2AMI). Age (OR per year = 1.03 (1.00, 1.05), = 0.03), prior MI (OR = 3.50 (1.68, 7.22), = 0.001), L/H \u3e 2.0 (OR = 1.55 (1.12, 2.13), = 0.007), percentage change in troponin I \u3e 25% (OR = 2.54 (1.38, 4.69), = 0.003), and regional wall motion abnormalities (RWMA) (OR = 3.53 (1.46, 8.54), = 0.004) were independent predictors of T1AMI, whereas sex, race, body mass index, hypertension, end-stage renal disease (ESRD), heart failure, family history (FH) of coronary artery disease (CAD), HbA, and left ventricular ejection fraction (LVEF) were not. CONCLUSIONS: Key clinical variables such as age, prior MI, L/H ratio, percentage change in troponin I, and presence of RWMA on echocardiogram may be utilized as significant predictors of T1AMI in patients presenting with ischemic symptoms to the ED

    Emergency department provider preferences related to clinical practice guidelines for tobacco cessation: a multicenter survey

    OBJECTIVES: The objective was to assess current emergency department (ED) provider practices and preferences for tobacco cessation interventions. The ED is an opportune place to initiate smoking cessation interventions. However, little is known about ED provider current practices and preferences for cessation counseling in the ED. METHODS: This was a survey of ED providers conducted in 2008-2009 (including physicians, nurse practitioners, physician assistants, and nurses), working at least half-time at 10 U.S. academic EDs, regarding adherence to clinical practice guidelines ( 5 As ) and preferences for cessation interventions/styles. Data analysis occurred in 2012-2013. RESULTS: The response rate was 64% (800 out of 1,246 completed surveys). Providers reported strongest adherence to asking about patient smoking status, followed by advising, with significant variance by clinical role. Assessing, assisting, and arranging support for patients was low overall. Most frequently used interventions were to provide patients with a list of telephone numbers for stop-smoking counseling (87%), pamphlets on smoking health risks and the benefits of stopping (85%), and referrals to the National Toll-Free Smoker\u27s Quitline (84%). Most providers (80%) were supportive of personally conducting brief (less than 3 minutes) smoking cessation counseling sessions during the ED visit, emphasizing education and encouragement. The least appealing intervention was writing a prescription for nicotine replacement therapies or medications to stop smoking (35%). CONCLUSIONS: Interventions most likely to be used were brief and delivered with a positive tone and included referral to external resources. The logical next step is to design and test interventions that ED providers find acceptable

    Assessment of Physician Well-being, Part One: Burnout and Other Negative States

    No full text
    Physician well-being is a complex and multifactorial issue. A large number of tools have been developed in an attempt to measure the nature, severity, and impact of both burnout and well-being in a range of clinical populations. This two-article series provides a review of relevant tools and offers guidance to clinical mentors and researchers in choosing the appropriate instrument to suit their needs, whether assessing mentees or testing interventions in the research setting. Part One begins with a discussion of burnout and focuses on assessment tools to measure burnout and other negative states. Part Two of the series examines the assessment of well-being, coping skills, and other positive states

    A multicenter observational study of US adults with acute asthma: who are the frequent users of the emergency department?

    BackgroundDespite the substantial burden of asthma-related emergency department (ED) visits, there have been no recent multicenter efforts to characterize this high-risk population.ObjectiveWe aimed to characterize patients with asthma according to their frequency of ED visits and to identify factors associated with frequent ED visits.MethodsA multicenter chart review study of 48 EDs across 23 US states. We identified ED patients ages 18 to 54 years with acute asthma during 2011 and 2012. Primary outcome was frequency of ED visits for acute asthma in the past year, excluding the index ED visit.ResultsOf the 1890 enrolled patients, 863 patients (46%) had 1 or more (frequent) ED visits in the past year. Specifically, 28% had 1 to 2 visits, 11% had 3 to 5 visits, and 7% had 6 or more visits. Among frequent ED users, guideline-recommended management was suboptimal. For example, of patients with 6 or more ED visits, 85% lacked evidence of prior evaluation by an asthma specialist, and 43% were not treated with inhaled corticosteroids. In a multivariable model, significant predictors of frequent ED visits were public insurance, no insurance, and markers for chronic asthma severity (all P < .05). Stronger associations were found among those with a higher frequency of asthma-related ED visits (eg, 6 or more ED visits).ConclusionThis multicenter study of US adults with acute asthma demonstrated many frequent ED users and suboptimal preventive management in this high-risk population. Future reductions in asthma morbidity and associated health care utilization will require continued efforts to bridge these major gaps in asthma care
