Cognitive impairment and treatment strategy for atrial fibrillation in older adults: The SAGE-AF study.

BACKGROUND: Cognitive impairment is strongly associated with atrial fibrillation (AF). Rate and rhythm control are the two treatment strategies for AF and the effect of treatment strategy on risk of cognitive decline and frailty is not well established. We sought to determine how treatment strategy affects geriatric-centered outcomes. METHODS: The Systematic Assessment of Geriatric Elements-AF (SAGE-AF) was a prospective, observational, cohort study. Older adults with AF were prospectively enrolled between 2016 and 2018 and followed longitudinally for 2 years. In a non-randomized fashion, participants were grouped by rate or rhythm control treatment strategy based on clinical treatment at enrollment. Baseline characteristics were compared. Longitudinal binary mixed models were used to compare treatment strategy with respect to change in cognitive function and frailty status. Cognitive function and frailty status were assessed with the Montreal Cognitive Assessment Battery and Fried frailty phenotype tools. RESULTS: 972 participants (mean age = 75, SD = 6.8; 49% female, 87% non-Hispanic white) completed baseline examination and 2-year follow-up. 408 (42%) were treated with rate control and 564 (58%) with rhythm control. The patient characteristics of the two groups were different at baseline. Participants in the rate control group were older, more likely to have persistent AF, prior stroke, be treated with warfarin and have baseline cognitive impairment. After adjusting for baseline differences, participants treated with rate control were 1.5 times more likely to be cognitively impaired over 2 years (adjusted OR: 1.47, 95% CI:1.12, 1.98) and had a greater decline in cognitive function (adjusted estimate: -0.59 (0.23), p < 0.01) in comparison to rhythm control. Frailty did not vary between the treatment strategies. CONCLUSIONS: Among those who had 2-year follow-up in non-randomized observational cohort, the decision to rate control AF in older adults was associated with increased odds of decline in cognitive function but not frailty.

Cognitive impairment, age, quality of life, and treatment strategy for atrial fibrillation in older adults: The SAGE-AF study.

BACKGROUND: Atrial fibrillation (AF) treatment includes anticoagulation for high stroke risk individuals and either rate or rhythm control strategies. We aimed to investigate the impact of age, geriatric factors, and medical comorbidities on choice of rhythm versus rate control strategy in older adults. METHODS: Patients with AF aged ≥65 years with CHA2 DS2 VASc score ≥2 and eligible for anticoagulation were recruited for the Systematic Assessment of Geriatric Elements-AF (SAGE-AF) prospective cohort study. An interview that included measures of HRQoL, cognitive function, vision, hearing, and frailty was performed. The association between these elements and AF treatment strategy was examined by multivariable logistic regression models. RESULTS: One thousand two hundred forty-four participants (mean age 76 years; 49% female; 85% non-Hispanic white) were enrolled. Rate and rhythm control were used in 534 and 710 participants, respectively. Compared to participants <75 years, those ≥75 were more likely to be treated with a rate control strategy (age 75-84 adjusted odds ratio [aOR] 1.37 [95% CI 0.99, 1.88]; age 85+ aOR = 2.05, 95% CI 1.30, 3.21). Those treated with a rate control strategy were more likely to have cognitive impairment (aOR = 1.50, 95% CI 1.13, 1.99), and peripheral vascular disease (PVD) (aOR = 1.82, 95% CI 1.22, 2.72) but less likely to have visual impairment (aOR 0.73 [0.55, 0.98]), congestive heart failure (CHF; aOR 0.68 [0.49, 0.94]) or receive anticoagulation (aOR 0.53, 95% CI 0.36, 0.78). CONCLUSION: Older age, cognitive impairment, and PVD were associated with use of rate control strategy. Visual impairment, CHF, and anticoagulation use were associated with a rhythm control strategy. There was no difference in HRQoL between the rate and rhythm control groups. This study suggests that certain geriatric elements may be associated with AF treatment strategies. Further study is needed to evaluate how these decisions affect outcomes.

School-supervised Asthma Therapy is Associated with Improved Long-Term Asthma Outcomes for Underrepresented Minority Children.

Asthma morbidity disproportionately impacts children from low-income and racial/ethnic minority communities. School-supervised asthma therapy improves asthma outcomes for up to 15 months for underrepresented minority children, but little is known about whether these benefits are sustained over time. We examined the frequency of emergency department (ED) visits and hospital admissions for 83 children enrolled in Asthma Link, a school nurse-supervised asthma therapy program serving predominantly underrepresented minority children. We compared outcomes between the year preceding enrollment and years one-four post-enrollment. Compared with the year prior to enrollment, asthma-related ED visits decreased by 67.9% at one year, 59.5% at two years, 70.2% at three years, and 50% at four years post-enrollment (all p-values< 0.005). There were also significant declines in mean numbers of total ED visits, asthma-related hospital admissions, and total hospital admissions. Our results indicate that school nurse-supervised asthma therapy could potentially mitigate racial/ethnic and socioeconomic inequities in childhood asthma.

Characteristics Associated With Facebook Use and Interest in Digital Disease Support Among Older Adults With Atrial Fibrillation: Cross-Sectional Analysis of Baseline Data From the Systematic Assessment of Geriatric Elements in Atrial Fibrillation (SAGE-AF) Cohort.

BACKGROUND: Online support groups for atrial fibrillation (AF) and apps to detect and manage AF exist, but the scientific literature does not describe which patients are interested in digital disease support. OBJECTIVE: The objective of this study was to describe characteristics associated with Facebook use and interest in digital disease support among older patients with AF who used the internet. METHODS: We used baseline data from the Systematic Assessment of Geriatric Elements in Atrial Fibrillation (SAGE-AF), a prospective cohort of older adults (≥65 years) with AF at high stroke risk. Participants self-reported demographics, clinical characteristics, and Facebook and technology use. Online patients (internet use in the past 4 weeks) were asked whether they would be interested in participating in an online support AF community. Mobile users (owns smartphone and/or tablet) were asked about interest in communicating with their health care team about their AF-related health using a secure app. Logistic regression models identified crude and multivariable predictors of Facebook use and interest in digital disease support. RESULTS: Online patients (N=816) were aged 74.2 (SD 6.6) years, 47.8% (390/816) were female, and 91.1% (743/816) were non-Hispanic white. Roughly half (52.5%; 428/816) used Facebook. Facebook use was more common among women (adjusted odds ratio [aOR] 2.21, 95% CI 1.66-2.95) and patients with mild to severe depressive symptoms (aOR 1.50, 95% CI 1.08-2.10) and less common among patients aged ≥85 years (aOR 0.27, 95% CI 0.15-0.48). Forty percent (40.4%; 330/816) reported interest in an online AF patient community. Interest in an online AF patient community was more common among online patients with some college/trade school or Bachelors/graduate school (aOR 1.70, 95% CI 1.10-2.61 and aOR 1.82, 95% CI 1.13-2.92, respectively), obesity (aOR 1.65, 95% CI 1.08-2.52), online health information seeking at most weekly or multiple times per week (aOR 1.84, 95% CI 1.32-2.56 and aOR 2.78, 95% CI 1.86-4.16, respectively), and daily Facebook use (aOR 1.76, 95% CI 1.26-2.46). Among mobile users, 51.8% (324/626) reported interest in communicating with their health care team via a mobile app. Interest in app-mediated communication was less likely among women (aOR 0.48, 95% CI 0.34-0.68) and more common among online patients who had completed trade school/some college versus high school/General Educational Development (aOR 1.95, 95% CI 1.17-3.22), sought online health information at most weekly or multiple times per week (aOR 1.86, 95% CI 1.27-2.74 and aOR 2.24, 95% CI 1.39-3.62, respectively), and had health-related apps (aOR 3.92, 95% CI 2.62-5.86). CONCLUSIONS: Among older adults with AF who use the internet, technology use and demographics are associated with interest in digital disease support. Clinics and health care providers may wish to encourage patients to join an existing online support community for AF and explore opportunities for app-mediated patient-provider communication.

Gait Speed and Mood, Cognition, and Quality of Life in Older Adults With Atrial Fibrillation.

Background Low gait speed has been linked with impaired mood, cognition, and quality of life (QOL) in older adults. We examined whether low gait speed was associated with impaired mood, cognition, and QOL among older adults with atrial fibrillation (AF). Methods and Results Participants (n=1185) had a diagnosis of AF, aged ≥65 years, CHA2DS2VASc ≥2 and had no contraindications to anticoagulation. Participants completed a 15-foot walk test, and low gait speed was categorized using cutoffs from the Fried Frailty Index. Participants self-reported measures of depressive symptoms (Patient Health Questionnaire 9 ≥10), anxiety symptoms (Generalized Anxiety Disorder 7 ≥10), cognitive impairment (Montreal Cognitive Assessment ≤23), and potentially impaired Atrial Fibrillation Effect Quality-of-Life Questionnaire <80. Participants were on average aged 75.3 (SD: 7.0) years, 48.0% were women, and 85.5% were non-Hispanic white; 85.6% were taking an oral anticoagulant, 26.1% had low gait speed, 8.4% had elevated depressive symptoms, 5.7% had elevated anxiety symptoms, 41.1% were cognitively impaired, and 41.6% had potentially impaired AF-related QOL. Participants with low gait speed were significantly more likely to have elevated depressive symptoms (adjusted odds ratio: 2.1, 95% CI: 1.3-3.4), elevated anxiety symptoms (adjusted odds ratio: 2.2, 95% CI: 1.2-3.9), and cognitive impairment (adjusted odds ratio: 1.5, 95% CI: 1.1-2.1). Impaired AF-related QOL did not differ by gait speed after adjustment for clinical characteristics (adjusted odds ratio: 1.1, 95% CI: 0.8-1.5). Conclusions Twenty-six percent of older adults with AF had low gait speed, and low gait speed was associated with impaired mood and cognition. Further research is needed to determine whether declines in gait speed lead to impaired mood and cognition or whether these conditions develop concurrently.

Religious practices and changes in health-related quality of life after hospital discharge for an acute coronary syndrome.

BACKGROUND: Religious beliefs and practices influence coping mechanisms and quality of life in patients with various chronic illnesses. However, little is known about the influence of religious practices on changes in health-related quality of life (HRQOL) among hospital survivors of an acute coronary syndrome (ACS). The present study examined the association between several items assessing religiosity and clinically meaningful changes in HRQOL between 1 and 6 months after hospital discharge for an ACS. METHODS: We recruited patients hospitalized for an ACS at six medical centers in Central Massachusetts and Georgia (2011-2013). Participants reported making petition prayers for their health, awareness of intercessory prayers by others, and deriving strength/comfort from religion. Generic HRQOL was assessed with the SF-36®v2 physical and mental component summary scores. Disease-specific HRQOL was evaluated using the Seattle Angina Questionnaire Quality of Life subscale (SAQ-QOL). We separately examined the association between each measure of religiosity and the likelihood of experiencing clinically meaningful increase in disease-specific HRQOL (defined as increases by ≥10.0 points) and Generic HRQOL (defined as increases by ≥3.0 points) between 1- and 6-months post-hospital discharge. RESULTS: Participants (n = 1039) were, on average, 62 years old, 33% were women, and 86% were non-Hispanic White. Two-thirds reported praying for their health, 88% were aware of intercessions by others, and 85% derived strength/comfort from religion. Approximately 42, 40, and 26% of participants experienced clinically meaningful increases in their mental, physical, and disease-specific HRQOL respectively. After adjustment for sociodemographic, psychosocial, and clinical characteristics, petition (aOR:1.49; 95% CI: 1.09-2.04) and intercessory (aOR:1.72; 95% CI: 1.12-2.63) prayers for health were associated with clinically meaningful increases in disease-specific and physical HRQOL respectively. CONCLUSIONS: Most ACS survivors in a contemporary, multiracial cohort acknowledged praying for their health, were aware of intercessory prayers made for their health and derived strength and comfort from religion. Patients who prayed for their health and those aware of intercessions made for their health experienced improvement in their generic physical and disease-specific HRQOL over time. Healthcare providers should recognize that patients may use prayer as a coping strategy for improving their well-being and recovery after a life-threatening illness.

Recent Trends in Oral Anticoagulant Use and Post-Discharge Complications Among Atrial Fibrillation Patients with Acute Myocardial Infarction.

BACKGROUND: Atrial fibrillation (AF) is a common complication of acute myocardial infarction (AMI).The CHA2DS2VAScand CHADS2risk scoresare used to identifypatients with AF at risk for strokeand to guide oral anticoagulants (OAC) use, including patients with AMI. However, the epidemiology of AF, further stratifiedaccording to patients' risk of stroke, has not been wellcharacterized among those hospitalized for AMI. METHODS: We examined trends in the frequency of AF, rates of discharge OAC use, and post-discharge outcomes among 6,627 residents of the Worcester, Massachusetts area who survived hospitalization for AMI at 11 medical centers between 1997 and 2011. RESULTS: A total of 1,050AMI patients had AF (16%) andthe majority (91%)had a CHA2DS2VAScscore >2.AF rates were highest among patients in the highest stroke risk group.In comparison to patients without AF, patients with AMI and AF in the highest stroke risk category had higher rates of post-discharge complications, including higher 30-day re-hospitalization [27 % vs. 17 %], 30-day post-discharge death [10 % vs. 5%], and 1-year post-discharge death [46 % vs. 18 %] (p < 0.001 for all). Notably, fewerthan half of guideline-eligible AF patientsreceived an OACprescription at discharge. Usage rates for other evidence-based therapiessuch as statins and beta-blockers,lagged in comparison to AMI patients free from AF. CONCLUSIONS: Our findings highlight the need to enhance efforts towards stroke prevention among AMI survivors with AF.

Indexed Left Atrial Adipose Tissue Area Is Associated With Severity of Atrial Fibrillation and Atrial Fibrillation Recurrence Among Patients Undergoing Catheter Ablation.

Background: Epicardial adipose tissue (EAT) has been associated with adverse left atrial (LA) remodeling and atrial fibrillation (AF) outcomes, possibly because of paracrine signaling. Objectives: We examined factors associated with a novel measure of EAT i.e., indexed LAEAT (iLAEAT) and its prognostic significance after catheter ablation (CA) of atrial fibrillation (AF). Methods: We performed a retrospective analysis of 274 participants with AF referred for CA. LAEAT area was measured from a single pre-ablation CT image and indexed to body surface area (BSA) to calculate iLAEAT. Clinical, echocardiographic data and 1-year AF recurrence rates after CA were compared across tertiles of iLAEAT. We performed logistic regression analysis adjusting for factors associated with AF to examine relations between iLAEAT and AF recurrence. Results: Mean age of participants was 61 ± 10 years, 136 (49%) were women, mean BMI was 32 ± 9 kg/m2 and 85 (31%) had persistent AF. Mean iLAEAT was 0.82 ± 0.53 cm2/m2. Over 12-months, 109 (40%) had AF recurrence. Participants in the highest iLAEAT tertile were older, had higher CHA2DS2VASC scores, more likely to be male, have greater LA volume, and were more likely to have persistent (vs. paroxysmal) type AF than participants in the lowest iLAEAT tertile (p for all < 0.05). In regression analyses, iLAEAT was associated with higher odds of AF recurrence (OR = 2.93; 95% CI 1.34-6.43). Conclusions: iLAEAT can quantify LA adipose tissue burden using standard CT images. It is strongly associated with AF risk factors and outcomes, supporting the hypothesis that EAT plays a role in the pathophysiology of AF.

Survivors of an Acute Coronary Syndrome With Lower Patient Activation Are More Likely to Experience Declines in Health-Related Quality of Life.

BACKGROUND: Patient activation comprises the knowledge, skills, and confidence for self-care and may lead to better health outcomes. OBJECTIVES: We examined the relationship between patient activation and changes in health-related quality of life (HRQOL) after hospitalization for an acute coronary syndrome (ACS). METHODS: We studied patients from 6 medical centers in central Massachusetts and Georgia who had been hospitalized for an ACS between 2011 and 2013. At 1 month after hospital discharge, the patients completed the 6-item Patient Activation Measure and were categorized into 4 levels of activation. Multinomial logistic regression analyses compared activation level with clinically meaningful changes (≥3.0 points, generic; ≥10.0 points, disease-specific) in generic physical (SF-36v2 Physical Component Summary [PCS]), generic mental (SF-36v2 Mental Component Summary [MCS]), and disease-specific (Seattle Angina Questionnaire [SAQ]) HRQOL from 1 to 3 and 1 to 6 months after hospitalization, adjusting for potential sociodemographic and clinical confounders. RESULTS: The patients (N = 1042) were, on average, 62 years old, 34% female, and 87% non-Hispanic white. A total of 10% were in the lowest level of activation. The patients with the lowest activation had 1.95 times (95% confidence interval, 1.05-3.62) and 2.18 times (95% confidence interval, 1.17-4.05) the odds of experiencing clinically significant declines in MCS and SAQ HRQOL, respectively, between 1 and 6 months than the most activated patients. The patient activation level was not associated with meaningful changes in PCS scores. CONCLUSIONS: Hospital survivors of an ACS with lower activation may be more likely to experience declines in mental and disease-specific HRQOL than more-activated patients, identifying a group at risk of poor outcomes.

Practical Care Support During the Early Recovery Period After Acute Coronary Syndrome.

OBJECTIVE: To describe the prevalence and predictors of receipt of practical support among acute coronary syndrome (ACS) survivors during the early post-discharge period. METHOD: 406 ACS patients were interviewed about receipt of practical (instrumental and informational) support during the week after discharge. Demographic, clinical, functional, and psychosocial predictors of instrumental and informational practical support were examined. RESULTS: 81% of participants reported receiving practical support during the early post-discharge period: 75% reported receipt of instrumental support and 51% reported receipt of informational support. Men were less likely to report receiving certain types of practical support, whereas married participants and those with higher education, impaired health literacy, impaired activities of daily living, and in-hospital complications were more likely to report receiving certain types of practical support. CONCLUSION: Receipt of practical support is very common among ACS survivors during the early post-discharge period, and type of support received differs according to patient characteristics.

Relation of Atrial Fibrillation in Acute Myocardial Infarction to In-Hospital Complications and Early Hospital Readmission.

Atrial fibrillation (AF) is a common complication of acute myocardial infarction (AMI) and contributes to high rates of in-hospital adverse events. However, there are few contemporary studies examining rates of AF in the contemporary era of AMI or the impact of new-onset AF on key in-hospital and postdischarge outcomes. We examined trends in AF in 6,384 residents of Worcester, Massachusetts, who were hospitalized with confirmed AMI during 7 biennial periods between 1999 and 2011. Multivariate logistic regression analysis was used to examine associations between occurrence of AF and various in-hospital and postdischarge complications. The overall incidence of AF complicating AMI was 10.8%. Rates of new-onset AF increased from 1999 to 2003 (9.8% to 13.2%), and decreased thereafter. In multivariable adjusted models, patients developing new-onset AF after AMI were at a higher risk for in-hospital stroke (odds ratio [OR] 2.5, 95% confidence interval [CI] 1.6 to 4.1), heart failure (OR 2.0, 95% CI 1.7 to 2.4), cardiogenic shock (OR 3.7, 95% CI 2.8 to 4.9), and death (OR 2.3, 95% CI 1.9 to 3.0) than patients without AF. Development of AF during hospitalization for AMI was associated with higher rates of readmission within 30 days after discharge (21.7% vs 16.0%), but no significant difference was noted in early postdischarge 30-day all-cause mortality rates (8.3% vs 5.1%). In conclusion, new-onset AF after AMI is strongly related to in-hospital complications of AMI and higher short-term readmission rates.

Elevated serum glucose levels and survival after acute heart failure: a population-based perspective.

BACKGROUND: Limited data are available about the characteristics, treatment and survival in patients without diabetes mellitus (DM), previously diagnosed DM and patients with hyperglycaemia who present with acute decompensated heart failure (ADHF). Our objectives were to examine differences in these endpoints in patients hospitalized with ADHF. METHODS: Patients hospitalized with ADHF during 1995, 2000, 2002 and 2004 comprised the study population. RESULTS: A total of 5428 non-diabetic patients were hospitalized with ADHF, 3807 with diagnosed DM and 513 with admission hyperglycaemia. Patients with admission hyperglycaemia experienced the highest in-hospital death rates (9.9%) compared to those with diagnosed DM (6.5%) and non-diabetics (7.5%). Patients with diagnosed DM had the greatest risk of dying after hospital discharge. CONCLUSIONS: Patients with elevated blood glucose levels at hospital admission are more likely to die acutely. After resolution of the acute illness, patients with previously diagnosed DM need careful monitoring and enhanced treatment.

Cognitive impairment and self-care in heart failure.

BACKGROUND: Heart failure (HF) is a prevalent chronic disease in older adults that requires extensive self-care to prevent decompensation and hospitalization. Cognitive impairment may impact the ability to perform HF self-care activities. We examined the association between cognitive impairment and adherence to self-care in patients hospitalized for acute HF. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: A total of 577 patients (mean age = 71 years, 44% female) hospitalized for HF at five medical centers in the United States and Canada. MEASUREMENTS AND METHODS: Participants were interviewed for information on self-reported adherence to self-care using the European Heart Failure Self-care Behaviour Scale. We assessed cognitive impairment in three domains (memory, processing speed, and executive function) using standardized measures. Patients' demographic and clinical characteristics were obtained through medical record review. Multivariable linear regression was used to examine the association between cognitive impairment and self-care practices adjusting for demographic and clinical factors. RESULTS: A total of 453 patients (79%) were impaired in at least one cognitive domain. Average adherence to self-care activities among patients with global cognitive impairment did not differ significantly from those without cognitive impairment (30.5 versus 29.6; 45-point scale). However, impaired memory was associated with lower self-care scores (P = 0.006) in multivariable models. CONCLUSION: Cognitive impairment is highly prevalent among older patients hospitalized for HF. Memory impairment is associated with poorer adherence to self-care practices. Screening for memory impairment in patients with HF may help to identify patients at risk for poor self-care who may benefit from tailored disease management programs.

Venous thromboembolism in patients with symptomatic atherosclerosis.

Patients with atherosclerosis have an increased risk of venous thromboembolism (VTE). We studied patients in the population-based Worcester VTE Study of 1,822 consecutive patients with validated VTE to compare clinical characteristics, prophylaxis, treatment, and outcomes of VTE in patients with and without symptomatic atherosclerotic cardiovascular disease, defined as history of ischaemic heart disease, history of positive cardiac catheterisation, percutaneous coronary intervention, or coronary artery bypass graft surgery, or history of peripheral artery disease. Of the 1,818 patients with VTE, 473 (26%) had a history of symptomatic atherosclerosis. Patients with atherosclerosis were significantly older (mean age 71.9 years vs. 61.6 years) and were more likely to have immobility (57.2% vs. 46.7%), prior heart failure (36.9% vs. 10.7%), chronic lung disease (26.4% vs. 15.5%), cerebrovascular disease (18.1% vs. 9.8%), and chronic kidney disease (4.9% vs. 1.9%) (all p<0.001) compared with non-atherosclerosis patients. Thromboprophylaxis was omitted in more than one-third of atherosclerosis patients who had been hospitalised for non-VTE-related illness or had undergone major surgery within the three months prior to VTE. Patients with atherosclerosis were significantly more likely to suffer in-hospital major bleeding (7.6% vs. 3.8%, p=0.0008). In conclusion, patients with atherosclerosis and VTE are more likely to suffer a complicated hospital course. Despite a high frequency of comorbid conditions contributing to the risk of VTE, we observed a low rate of thromboprophylaxis in patients with symptomatic atherosclerosis.

Venous thromboembolism in heart failure: preventable deaths during and after hospitalization.

OBJECTIVE: Our aim was to compare the clinical characteristics, prophylaxis, treatment, and outcomes of patients with venous thromboembolism with and without heart failure. METHODS: We studied patients with heart failure in the population-based Worcester Venous Thromboembolism Study of 1822 consecutive patients with validated venous thromboembolism. RESULTS: Of the 1822 patients with venous thromboembolism, 319 (17.5%) had a history of clinical heart failure and 1503 (82.5%) did not. Patients with heart failure were older (mean age 75 vs 62 years, P<.0001) and more likely to have been immobilized (65.2% vs 46.1%, P<.0001). Thromboprophylaxis was omitted in approximately one third of patients with heart failure who had been hospitalized for non-venous thromboembolism-related illness or had undergone major surgery within the 3 months before diagnosis. Patients with heart failure had a higher frequency of in-hospital death (9.7% vs 3.3%, P<.0001) and death within 30 days of venous thromboembolism diagnosis (15.6% vs 6.4%, P<.0001). Heart failure (adjusted odds ratio [OR] 2.04; 95% confidence interval [CI], 1.15-3.62) and immobility (adjusted OR 4.37; 95% CI, 2.42-7.9) were associated with an increased risk of in-hospital death. Heart failure (adjusted OR 1.57; 95% CI, 1.01-2.43) and immobility (adjusted OR 3.05; 95% CI, 2.01-4.62) also were independent predictors of death within 30 days of venous thromboembolism diagnosis. CONCLUSION: High mortality was observed among patients with heart failure and venous thromboembolism both during and after hospitalization. Heart failure and immobility are potent risk factors for in-hospital death and death within 30 days in patients with venous thromboembolism.

Do-not-resuscitate orders in patients hospitalized with acute myocardial infarction: the Worcester Heart Attack Study.

BACKGROUND: Coronary heart disease is the leading cause of death in Americans. Despite increased interest in end-of-life care, data regarding the use of do-not-resuscitate (DNR) orders in acutely ill cardiac patients remain extremely limited. The objectives of this study were to describe use of DNR orders, treatment approaches, and hospital outcomes in patients with acute myocardial infarction. METHODS: The study sample consisted of 4621 residents hospitalized with acute myocardial infarction at all metropolitan Worcester, Mass, area hospitals in five 1-year periods from 1991 to 1999. RESULTS: Significant increases in the use of DNR orders were observed during the study decade (from 16% in 1991 to 25% in 1999). The elderly, women, and patients with previous diabetes mellitus or stroke were more likely to have DNR orders. Patients with DNR orders were significantly less likely to be treated with effective cardiac medications, even if the DNR order occurred late in the hospital stay. Less than 1% of patients were noted to have DNR orders before hospital admission. Patients with DNR orders were significantly more likely to die during hospitalization than patients without DNR orders (44% vs 5%). CONCLUSIONS: The results of this community-wide study suggest increased use of DNR orders in patients hospitalized with acute myocardial infarction during the past decade. Use of certain cardiac therapies and hospital outcomes are different between patients with and without DNR orders. Further efforts are needed to characterize the use of DNR orders in patients with acute coronary disease.
