Among patients with severe aortic stenosis (AS), there are limited data on aortic valve replacement (AVR), reasons for nonreceipt and mortality by race.Utilizing the Duke Echocardiography Laboratory Database, we analyzed data from 110,711 patients who underwent echocardiography at Duke University Medical Center between 1999 and 2013. We identified 1,111 patients with severe AS who met ≥1 of 3 criteria for AVR: ejection fraction ≤50%, diagnosis of heart failure, or need for coronary artery bypass surgery. Logistic regression models were used to assess the association between race, AVR and 1-year mortality. χ2 testing was used to assess potential racial differences in reasons for AVR nonreceipt.Among the 1,111 patients (143 AA and 968 CA) eligible for AVR, AA were more often women, had more diabetes, renal insufficiency, aortic regurgitation and left ventricular hypertrophy. CA were more often smokers, had more ischemic heart disease, hyperlipidemia and higher median income levels. There were no racial differences in surgical risk utilizing logistic euroSCORES. Relative to CA, AA had lower rates of AVR (adjusted odds ratio 0.46, 95% CI 0.3-0.71, P.001) yet similar 1-year mortality (aHR 0.81, 95% CI 0.57-1.17, P = .262). There were no significant differences in reasons for AVR nonreceipt.We identified 143 African Americans (AA) and 968 Caucasian Americans(CA) with severe AS who met prespecified criteria for AVR.. AA relative to CA were more often women, had more diabetes, renal insufficiency, and left ventricular hypertrophy, however had less tobacco use, ischemic heart disease, hyperlipidemia and lower median income levels. Among patients with severe AS, AA relative to CA had lower rates of AVR (adjusted odds ratio 0.46, 95% CI 0.3-0.71, P.001) without significant differences in reasons for AVR nonreceipt and similar 1-year mortality.

The goal of this study was to evaluate differences in clinical and patient-reported outcomes between women and men hospitalized for acute HF.Among patients hospitalized for heart failure (HF), it is unclear if symptom burden, response to therapy, and patient-reported quality of life (QOL) are different in women as compared with men.The ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure) trial randomized 7,141 patients hospitalized for HF with reduced or preserved ejection fraction (EF) to receive nesiritide or placebo in addition to standard care. Clinical endpoints included 30-day mortality and rehospitalization and 180-day mortality. Patient-reported QOL was assessed at baseline, discharge, and 30 days using the EuroQOL 5 dimensions (EQ-5D) survey.Among 7,141 total patients, 4,697 (65.8%) were men and 2,444 (34.2%) were women. Among patients with EF ≤40%, women were less likely to receive angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker and beta-blocker therapy, and less likely to have an implantable cardioverter-defibrillator (all p 0.03). Signs and symptoms of HF were similar between men and women (all p0.05), but women experienced less in-hospital weight loss and urine output (all p 0.01). In unadjusted and adjusted analyses, men and women had similar risk of all mortality and rehospitalization endpoints (all p ≥ 0.41). Women reported lower EQ-5D utility and visual analogue scores at admission, discharge, and 30 days. Women continued to have significantly lower EQ-5D scores at all in-hospital and post-discharge time points after adjustment for clinical characteristics (all p 0.01).In this acute HF population, women had similar risk of mortality and rehospitalization as compared with men, but experienced worse patient-reported QOL during and after hospitalization that persisted after adjustment for demographic and clinical factors. Current acute HF management may work similarly in either sex for purposes of preventing clinical events, but may be less equipped to improve patient-reported outcomes in women as compared with men.

Smoking is associated with incident heart failure (HF), yet limited data are available exploring the association between smoking status and long-term outcomes in HF with reduced vs. preserved ejection fraction (i.e., HFrEF vs. HFpEF).We performed a retrospective analysis of HF patients undergoing coronary angiography from 1990-2010. Patients with coronary artery disease (CAD) and HF were stratified by EF (50% vs. ≥50%), smoking status (prior/current vs. never smoker), and level of smoking (light/moderate vs. heavy). Time-from-catheterization-to-event was examined using Cox proportional hazard modeling for all-cause mortality (ACM), ACM/myocardial infarction/stroke (MACE), and ACM/HF hospitalization with testing for interaction by HF-type (HFrEF vs. HFpEF).Of 14,406 patients with CAD and HF, 85% (n = 12,326) had HFrEF and 15% (n = 2080) had HFpEF. At catheterization, 61% of HFrEF and 57% of HFpEF patients had a smoking history. After adjustment, there was a significant interaction between HF-type and the association between smoking status and MACE (interaction P = .009). Smoking history was associated with increased risk for MACE in patients with HFrEF (adjusted hazard ratio [HR] 1.18 [1.12-1.24]), but not HFpEF (HR 1.01 [0.90-1.12]). Active smokers had increased mortality following adjustment compared to former smokers regardless of HF-type (HFrEF HR 1.19 [1.06-1.32], HFpEF HR 1.30 [1.02-1.64], interaction P = .50). Heavy smokers trended towards increased risk of adverse outcomes versus light/moderate smokers; these findings were consistent across HF-type (interaction P .12).Smoking history was independently associated with worse outcomes in HFrEF but not HFpEF. Regardless of HF-type, current smokers had higher risk than former smokers.

Objectives Perioperative myocardial infarction (MI) after coronary artery bypass graft surgery (CABG) has been associated with adverse outcome. Whether perioperative MI should be treated with dual antiplatelet therapy (DAPT) is unknown. We compared the effect of DAPT versus aspirin alone on short-term outcomes among patients with perioperative MI following CABG. Methods We used data from 3 clinical trials that enrolled patients undergoing isolated CABG: PREVENT IV (2002–2003), MEND-CABG II (2004–2005), and RED-CABG (2009–2010) (n = 9117). Perioperative MI was defined as CK-MB >5 times the upper limit of normal within 24 h of surgery (n = 2052). DAPT was defined as DAPT given after surgery and prior to discharge. A Cox regression model was used to assess the association between DAPT and 30-day nonfatal MI, stroke, or mortality after adjustment for baseline covariates. Results DAPT (n = 527) and aspirin alone (n = 1525) cohorts were similar in baseline comorbidities. Off pump bypass was used in 5.2% (n = 106) of patients. There was no difference in the 30-day composite of death, MI or stroke between patients receiving DAPT versus aspirin alone, nor in any of the individual components. There were fewer all-cause re-hospitalizations at 30 days following surgery among patients in the DAPT group (adjusted HR 0.71, CI 0.52–0.97, P = .033). Conclusion One-quarter of CABG patients who had perioperative MI were treated with DAPT. DAPT was not associated with a difference in MI, stroke, or mortality at 30 days, but was associated with fewer re-hospitalizations. Further studies are needed to determine the optimal antiplatelet regimen following perioperative MI. What is already known about this subject? Perioperative myocardial infarction portends poor outcome but optimal management is currently unclear. While dual antiplatelet therapy is standard of care for acute coronary syndrome, its role in perioperative myocardial infarction is unknown. What does this study add? Dual antiplatelet therapy use during perioperative myocardial infarction was not associated with a difference in myocardial infarction, stroke or mortality at 30 days. It was, however, associated with fewer re-hospitalizations at 30 days. How might this impact on clinical practice? Dual antiplatelet therapy may be a potential treatment option for perioperative myocardial infarction after CABG surgery. Further studies are needed to better understand treatment for this disease process.

Objectives As the largest acute heart failure (AHF) trial conducted to date, the global ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure) trial database presented an opportunity to systematically describe the relationship among time of hospital presentation, clinical profile, inpatient management, and outcomes among patients admitted with AHF. Background Time of hospital presentation has been shown to impact outcomes among patients hospitalized with many conditions. However, the association among time of presentation and patient characteristics, management, and clinical outcomes among patients hospitalized with AHF has not been well characterized. Methods A post hoc analysis of the ASCEND-HF trial was performed, which enrolled 7,141 patients hospitalized for AHF. Patients were divided based on when they presented to the hospital; regular hours were defined as 9 am to 5 pm, Monday through Friday, and off hours were defined as 5 pm to 9 am, Monday through Friday and weekends. Clinical characteristics and outcomes were compared by time of presentation. Results Overall, 3,298 patients (46%) presented during off hours. Off-hour patients were more likely to have orthopnea (80% vs. 74%, respectively) and rales (56% vs. 49%, respectively) than regular-hour patients. Off-hour patients were more likely to receive intravenous (IV) nitroglycerin (18% vs. 11%, respectively) and IV loop diuretics (92% vs. 86%, respectively) as initial therapy and reported greater relief from dyspnea at 24 h (odds ratio [OR]: 1.14; 95% confidence interval [CI]: 1.04 to 1.24; p = 0.01) than regular-hour patients. After adjustment, off-hour presentation was associated with significantly lower 30-day mortality (OR: 0.74; 95% CI: 0.57 to 0.96; p = 0.03) and 180-day mortality (hazard ratio [HR]: 0.82; 95% CI: 0.72 to 0.94; p = 0.01) but similar 30-day rehospitalization rates (p = 0.40). Conclusions In this AHF trial, patients admitted during off hours exhibited a distinct clinical profile, experienced greater dyspnea relief, and had lower post-discharge mortality than regular-hour patients. These findings have implications for future AHF trials.

Background Although aerobic exercise improves quality of life as assessed by a disease-specific instrument in ambulatory HF patients with a reduced ejection fraction (EF), the impact of an exercise intervention on general health status has not been previously reported. Methods A secondary analysis was performed of the HF-ACTION trial (ClinicalTrials.gov Number: NCT00047437), which enrolled 2331 medically stable outpatients with HF and an EF ≤35% and randomized them to aerobic exercise training, consisting of 36 supervised sessions followed by home-based training versus usual care for a median follow-up of 30 months. The EuroQOL 5-dimension questionnaire (EQ-5D) was administered to study participants at baseline, 3 months, and 12 months. EQ-5D includes functional dimensions (ie, mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), which were mapped to corresponding utility scores (ie, 0=death and 1=perfect health), and a visual analogue scale (VAS) ranging from 0 (ie, "worst imaginable health state") to 100 (ie, "best imaginable health state"). Results Study participants had a median (25th, 75th) age of 59 (51, 68) years and 71% were male. A history of ischemic heart disease was reported in 51% of participants and the EF was 25% (20%, 30%). Baseline VAS and mapped utility scores were 65±19 and 0.81±0.14. Exercise training led to an improvement in VAS score compared with usual care from baseline to 3 months (exercise training: 6±17 vs usual care: 3±20; P P P Conclusion Ambulatory HF patients with a reduced EF had impaired health status at baseline which was associated with increased morbidity and mortality, in part mitigated by a structured aerobic exercise regimen.

BACKGROUND/OBJECTIVES: The extent to which individual knowledge, preferences, and priorities explain lower use of invasive cardiac care among older vs. younger adults presenting with acute coronary syndrome (ACS) is unknown. We directly surveyed a group of patients to ascertain their preferences and priorities for invasive cardiovascular care. DESIGN: We performed a prospective cohort study of adults hospitalized with ACS. We surveyed participants regarding their knowledge, preferences, goals, and concerns for cardiac care, as well as their risk tolerance for coronary artery bypass grafting (CABG). SETTING: Single academic medical center. PARTICIPANTS: 628 participants (373

Background Spinal cord infarction (SCI) is rare, accounting for approximately 1% of strokes. Case Report We present the case of a 63-year-old male who presented to the emergency department (ED) with chest pain and acute-onset generalized weakness and was ultimately diagnosed with SCI secondary to suspected occlusion of the artery of Adamkiewicz. Why Should an Emergency Physician Be Aware of This? SCI may present diagnostic challenges, with its predilection for mimicking other major emergency conditions, such as acute aortic dissection, aortic aneurysm rupture, spinal cord compressive myelopathy, or transverse myelitis. Its consequences are often significantly disabling initially, though patients may experience subsequent clinical improvement. It is important to include SCI in the differential for patients with chest or back pain coupled with neurologic symptoms.
