RESUMO

OBJECTIVE: Supplemental MRI screening for women at high risk for breast cancer is underutilized. Our study assessed how primary care providers in our healthcare network identify high-risk women and recommend high-risk screening breast MRI. METHODS: An electronic survey was distributed to providers in OB/GYN, family, and internal medicine departments between 1/14/19 and 3/22/19. The survey inquired about methods used to assess breast cancer risk, familiarity with the American Cancer Society's definition of high-risk, and whether screening breast MRI is recommended for high-risk women. RESULTS: Response rate was 17% (89/524). After excluding providers who ordered ≤10 mammograms per year, the study included 75 respondents, who mostly ordered 10-1000 mammograms per year and supported annual/biennial screening mammogram starting at age 40-50 years. More providers reported estimating breast cancer risk qualitatively (with family, clinical history, and/or breast density) than quantitatively with risk calculators (73/75, 97% vs 22/75, 29%). A minority of providers (23/75, 31%) correctly defined high lifetime risk. Only 9/75 (12%) providers recommended screening MRI for high-risk women. Use of quantitative risk calculators or ability to correctly define high-risk were not associated with likelihood of recommending MRI screening. More providers had recommended MRI for screening in the setting of dense breasts than for high-risk screening (23/75, 31% vs 9/75, 12%). CONCLUSION: Primary care providers at our institution did not routinely recommend screening MRI for high-risk women. Risk assessment and reporting at the time of mammography may improve MRI utilization and is an opportunity for radiologists to add value and directly participate in patient-centered care.

RESUMO

RATIONALE AND OBJECTIVES: Performing breast cancer risk assessment at the time of screening mammography has potential to increase high-risk identification, appropriate supplemental screening, and risk management. The study's goal is to investigate women's interest in risk assessment and preferred method of risk communication in a diverse patient population. MATERIALS AND METHODS: Surveys in English and five non-English languages were distributed to women presenting for screening mammography at eight screening mammography facilities between February and May 2019 to assess their interest in risk assessment, preferred method, and level of detail of estimated risk communication in hypothetical scenarios where estimated risks are average and elevated. RESULTS: Among 683 survey respondents, 592 (87%) expressed interest in learning about their estimated lifetime risk of breast cancer. Controlling for age, race/ethnicity, and education, women with higher income were more interested in risk assessment than comparison group (p<0.05). The most preferred method of average risk communication was by a mailed letter accompanying mammographic results (57%), but more women exclusively preferred face-to-face communications of elevated risk than of average risk estimate (191, 28% vs. 128, 19%, p<0.0001). Phone communication was more preferred by younger women, electronic communication was less preferred by older women and those with lower income, and non-Hispanic blacks and older women preferred less detailed communication (p<0.05). CONCLUSION: Sociodemographic factors influence women's interest in risk assessment and preference in risk communication about breast cancer. Screening Mammogram facilities implementing risk assessment should consider risk communication strategies that are most effective for their patient population.

RESUMO

BACKGROUND AND AIMS: Low body iodine levels are associated with cardiovascular disease, in part through alterations in thyroid function. While this association suggested from animal studies, it lacks supportive evidence in humans. This study examined the association between urine iodine levels and presence of coronary artery disease (CAD) and stroke in adults without thyroid dysfunction. METHODS AND RESULTS: This cross-sectional study included 2440 adults (representing a weighted n = 91,713,183) aged ≥40 years without thyroid dysfunction in the nationally-representative 2007-2012 National Health and Nutrition Examination Survey. The age and sex-adjusted urine iodine/creatinine ratio (aICR) was categorized into low (aICR<116 µg/day), medium (116 µg/day ≤ aICR < 370µg/day), and high (aICR ≥ 370µg/day) based on lowest/highest quintiles. Stroke and CAD were from self-reported physician diagnoses. We examined the association between low urine aICR and CAD or stroke using multivariable logistic regression modeling. The mean age of this population was 56.0 years, 47% were women, and three quarters were non-Hispanic whites. Compared with high urine iodine levels, multivariable adjusted odds ratios aOR (95% confidence intervals) for CAD were statistically significant for low, aOR = 1.97 (1.08-3.59), but not medium, aOR = 1.26 (0.75-2.13) urine iodine levels. There was no association between stroke and low, aOR = 1.12 (0.52-2.44) or medium, aOR = 1.48 (0.88-2.48) urine iodine levels. CONCLUSION: The association between low urine iodine levels and CAD should be confirmed in a prospective study with serial measures of urine iodine. If low iodine levels precede CAD, then this potential and modifiable new CAD risk factor might have therapeutic implications.

RESUMO

BACKGROUND: Living donor kidney transplant (LDKT) can be impeded by multiple barriers. One possible barrier to LDKT is a large physical distance between the living donor's home residence and the procuring transplant center. METHODS: We performed a retrospective, single-center study of living kidney donors in the United States who were geographically distant (residing ≥150 miles) from our transplant center. Each distant donor was matched to 4 geographically nearby donors (<150 miles from our center) as controls. RESULTS: From 2007 to 2010, of 429 live kidney donors, 55 (12.8%) were geographically distant. Black donors composed a higher proportion of geographically distant vs nearby donors (34.6% vs 15.5%), whereas Hispanic and Asian donors composed a lower proportion (P = .001). Distant vs nearby donors had similar median times from donor referral to actual donation (165 vs 161 days, P = .81). The geographically distant donors lived a median of 703 miles (25% to 75% range, 244 to 1072) from our center and 21.2 miles (25% to 75% range, 9.8 to 49.7) from the nearest kidney transplant center. The proportion of geographically distant donors who had their physician evaluation (21.6%), psychosocial evaluation (21.6%), or computed tomography angiogram (29.4%) performed close to home, rather than at our center, was low. CONCLUSIONS: Many geographically distant donors live close to transplant centers other than the procuring transplant center, but few of these donors perform parts of their donor evaluation at these closer centers. Black donors comprise a large proportion of geographically distant donors. The evaluation of geographically distant donors, especially among minorities, warrants further study.

RESUMO

INTRODUCTION: Contemporary trends in health-care delivery are shifting the management of venous thromboembolism (VTE) events (deep vein thrombosis [DVT] and/or pulmonary embolism [PE]) from the hospital to the community, which may have implications for its prevention, treatment, and outcomes. MATERIALS AND METHODS: Population-based surveillance study monitoring trends in clinical epidemiology among residents of the Worcester, Massachusetts, metropolitan statistical area (WMSA) diagnosed with an acute VTE in all 12 WMSA hospitals. Patients were followed for up to 3 years after their index event. Total of 2334 WMSA residents diagnosed with first-time community-presenting VTE (occurring in an ambulatory setting or diagnosed within 24 hours of hospitalization) from 1999 through 2009. RESULTS: While PE patients were consistently admitted to the hospital for treatment over time, the proportion diagnosed with DVT-alone admitted to the hospital decreased from 67% in 1999 to 37% in 2009 (p value for trend <0.001). Among hospitalized patients, the mean length of stay decreased from 5.6 to 4.8 days (p value for trend <0.001). Between 1999 and 2009, treatment of VTE shifted from warfarin and unfractionated heparin towards use of low-molecular-weight heparins and newer anticoagulants; also, 3-year cumulative event rates decreased for all-cause mortality (41-26%), major bleeding (12-6%), and recurrent VTE (17-9%). CONCLUSIONS: A decade of change in VTE management was accompanied by improved long-term outcomes. However, rates of adverse events remained fairly high in our population-based surveillance study, implying that new risk-assessment tools to identify individuals at increased risk for developing major adverse outcomes over the long term are needed.

RESUMO

OBJECTIVE: To compare the characteristics, management, and outcomes of patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS) who would have been eligible for inclusion in clinical trials of glycoprotein (GP) IIb/IIIa inhibitors with those of ineligible patients. DESIGN: Multinational, prospective, observational study (GRACE, Global Registry of Acute Coronary Events). SETTING: Patients hospitalised for a suspected acute coronary syndrome and enrolled in GRACE between April 1999 and December 2004. PATIENTS: 29 039 patients with NSTE ACS. MAIN OUTCOME MEASURES: Characteristics and outcomes were compared for trial-eligible (75.0%) and trial-ineligible (25.0%) patients. RESULTS: GP IIb/IIIa inhibitors were administered to 20.0% of eligible and 15.3% of ineligible patients. Compared with eligible patients, ineligible patients who received GP IIb/IIIa inhibitors had significantly higher rates of hospital death (6.8% vs 3.7%) and major bleeding (4.9% vs 2.2%). After adjustment for their higher baseline risk, ineligible patients still experienced higher hospital death rates (adjusted odds ratio (OR) 1.60; 95% confidence interval (CI) 1.01 to 2.39), but not higher bleeding rates, than the eligible group. Use of GP IIb/IIIa inhibitors was associated with a trend towards lower 6-month mortality in eligible (OR 0.86, 95% CI 0.72 to 1.02) and ineligible (OR 0.82, 95% CI 0.65 to 1.05) patients compared with those in whom this therapy was not used. CONCLUSIONS: GP IIb/IIIa inhibitors were markedly underused in the real-world population, irrespective of whether patients were trial-eligible or not. Despite the higher risk of ineligible patients, the benefits of GP IIb/IIIa inhibitors appear to be no less than in eligible patients.

RESUMO

AIMS: There have been no large observational studies attempting to identify predictors of major bleeding in patients with acute coronary syndromes (ACS), particularly from a multinational perspective. The objective of our study was thus to develop a prediction rule for the identification of patients with ACS at higher risk of major bleeding. METHODS AND RESULTS: Data from 24045 patients from the Global Registry of Acute Coronary Events (GRACE) were analysed. Factors associated with major bleeding were identified using logistic regression analysis. Predictive models were developed for the overall patient population and for subgroups of patients with ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI) and unstable angina. The overall incidence of major bleeding was 3.9% (4.8% in patients with STEMI, 4.7% in patients with NSTEMI and 2.3% in patients with unstable angina). Advanced age, female sex, history of bleeding, and renal insufficiency were independently associated with a higher risk of bleeding (P<0.01). The association remained after adjustment for hospital therapies and performance of invasive procedures. After adjustment for a variety of potential confounders, major bleeding was significantly associated with an increased risk of hospital death (adjusted odds ratio 1.64, 95% confidence interval 1.18, 2.28). CONCLUSIONS: In routine clinical practice, major bleeding is a relatively frequent non-cardiac complication of contemporary therapy for ACS and it is associated with a poor hospital prognosis. Simple baseline demographic and clinical characteristics identify patients at increased risk of major bleeding.

RESUMO

OBJECTIVE: To determine whether creatinine clearance at the time of hospital admission is an independent predictor of hospital mortality and adverse outcomes in patients with acute coronary syndromes (ACS). DESIGN: A prospective multicentre observational study, GRACE (global registry of acute coronary events), of patients with the full spectrum of ACS. SETTING: Ninety four hospitals of varying size and capability in 14 countries across four continents. PATIENTS: 11 774 patients hospitalised with ACS, including ST and non-ST segment elevation acute myocardial infarction and unstable angina. MAIN OUTCOME MEASURES: Demographic and clinical characteristics, medication use, and in-hospital outcomes were compared for patients with creatinine clearance rates of > 60 ml/min (normal and minimally impaired renal function), 30-60 ml/min (moderate renal dysfunction), and < 30 ml/min (severe renal dysfunction). RESULTS: Patients with moderate or severe renal dysfunction were older, were more likely to be women, and presented to participating hospitals with more comorbidities than those with normal or minimally impaired renal function. In comparison with patients with normal or minimally impaired renal function, patients with moderate renal dysfunction were twice as likely to die (odds ratio 2.09, 95% confidence interval 1.55 to 2.81) and those with severe renal dysfunction almost four times more likely to die (odds ratio 3.71, 95% confidence interval 2.57 to 5.37) after adjustment for other potentially confounding variables. The risk of major bleeding episodes increased as renal function worsened. CONCLUSION: In patients with ACS, creatinine clearance is an important independent predictor of hospital death and major bleeding. These data reinforce the importance of increased surveillance efforts and use of targeted intervention strategies in patients with acute coronary disease complicated by renal dysfunction.

RESUMO

Surveys estimate that 1.8 to 3.6 percent of workers in the U.S. labor force suffer from major depression. Depression has a significant impact on vocational functioning. Seventeen to 21 percent of the workforce experiences short-term disability during any given year, and 37 to 48 percent of workers with depression experience short-term disability. Studies indicate that treating workplace depression provides favorable cost offsets for employers, although a number of methodological issues have influenced the interpretation of these findings. In addition to disability costs, cost analyses need to include lost wages and indirect costs to employers, such as the costs of hiring and training new employees. In general, employers are not aware of the extent of the indirect costs of untreated depression. They have mistaken assumptions about the availability of effective treatment, and they are unaware of how often depression contributes to worker disability. The workers' compensation system and the courts have been slow to recognize depression as a work-related disability, and as a result employers have few incentives to treat and prevent workplace depression.

RESUMO

BACKGROUND: Evidence-based clinical practice guidelines recommend the use of warfarin sodium for stroke prevention in most patients with atrial fibrillation (AF) who do not have risk factors for hemorrhagic complications, irrespective of age. METHODS: The medical records of all residents of a convenience sample of long-term care facilities in Connecticut (n = 21) were reviewed. The percentages of all patients with AF (AF patients) and ideal candidates for warfarin therapy (ie, AF patients with no risk factors for hemorrhage) who received warfarin were determined; for patients receiving warfarin, the percentage of days spent in the therapeutic range of international normalized ratio (INR) values (2.0-3.0) was also assessed. The relationship between receipt of warfarin and the presence of stroke and bleeding risk factors was assessed in multivariate models. RESULTS: Atrial fibrillation was present in 429 (17%) of the 2587 long-term care residents. Overall, 42% of AF patients were receiving warfarin. However, only 44 (53%) of 83 ideal candidates were receiving this therapy. In residents who received warfarin therapy, the therapeutic range of INR values was maintained only 51% of the time. The odds of receiving warfarin in the study sample decreased with increasing number of risk factors for bleeding and increased (nonsignificant trend) with increasing number of stroke risk factors present. CONCLUSIONS: Atrial fibrillation is very common among residents of long-term care facilities. Even among apparently ideal candidates, warfarin therapy is underused for stroke prevention in patients with AF. Prescribing decisions and monitoring related to warfarin therapy in the long-term care setting warrant improvement.

RESUMO

BACKGROUND: Although there are an increasing number and variety of medications available for the treatment of patients with acute myocardial infarction (AMI), few data are available describing recent, and changes over time in, use of different cardiac medications in patients with AMI from a more generalizable, community-wide perspective. Moreover, it is unclear whether the demographic and clinical profile of patients receiving these agents is similar or varies according to the type of agent prescribed. METHODS AND RESULTS: The purpose of this study was to examine recent patterns and changes over a decade-long period (1986 to 1997) in the use of cardiac medications during the acute hospitalization and at the time of hospital discharge in metropolitan Worcester, Mass, residents (1990 census estimate, 437,000) hospitalized with confirmed AMI. There was a marked increase in the use of angiotensin-converting enzyme inhibitors, aspirin, beta-blockers, lipid-lowering agents, and thrombolytic therapy between 1986 and 1997. The use of calcium antagonists, lidocaine, and other antiarrhythmic agents declined over this period. Similar trends were observed in the use of these agents in hospital survivors at the time of hospital discharge. Patient age, presence of comorbidities, and AMI-associated characteristics influenced the use of these therapies; sex differences in the use of several of these medications were also noted. CONCLUSIONS: The results of this population-based observational study provide insights into changing prescribing patterns in the hospital treatment of patients with AMI. Despite encouraging increases in the use of several of these agents, considerable opportunities for increased utilization remain.

RESUMO

OBJECTIVES: We investigated whether elevated levels of circulating monocyte-platelet aggregates (MPA) can be used to identify patients with acute myocardial infarction (AMI). BACKGROUND: Commonly used blood markers of AMI reflect myocardial cell death, but do not reflect the earlier pathophysiologic processes of plaque rupture, platelet activation and resultant thrombus formation. Circulating MPA form after platelet activation. METHODS: In a single center between October 1998 and November 1999, we measured circulating MPA in a blinded fashion by whole blood flow cytometry in 211 consecutive patients who presented to the emergency department (ED) with chest pain and were admitted to rule out AMI. Acute myocardial infarction was diagnosed by a CK-MB fraction greater than three times control. RESULTS: Patients with AMI (n = 61), as compared with those without AMI (n = 150), had significantly higher numbers of circulating MPA (11.6 +/- 11.4 vs. 6.4 +/- 3.6, mean +/- SD, p < 0.0001). After controlling for age, the adjusted odds of developing AMI for patients in the 2nd, 3rd and 4th quartiles of MPA, in comparison with patients in the lowest quartile (odds ratio = 1.0), were 2.1 (95% confidence interval [CI]: 0.7, 6.8), 4.4 (95% CI: 1.5, 13.1) and 10.8 (95% CI: 3.6, 32.0), respectively. The number of circulating MPA in patients with AMI presenting within 4 h of symptom onset (14.4) was significantly greater than those presenting after 4 h (9.4) and after 8 h (7.0), (p < 0.001). Of the 61 patients with AMI, 35 (57%) had a normal creatine kinase isoenzyme ratio at the time of presentation to the ED, but had high levels of circulating MPA (13.3). CONCLUSIONS: Circulating MPA are an early marker of AMI.

RESUMO

Considerable data indicates that patients <50 years of age have lower morbidity and mortality after acute myocardial infarction (AMI) than older patients. It has been demonstrated that use of routine cardiac catheterization and revascularization in younger patients with AMI and successful thrombolysis does not confer benefit compared with a more conservative approach. Despite this, it has been our impression that cardiac catheterization is frequently employed in younger patients with AMI. Patients with uncomplicated initial AMI treated with thrombolytic therapy in the Second National Registry of Myocardial Infarction (NRMI-2) between June 1994 and April 1998 were identified. Patients were categorized into 4 age strata for purposes of analysis. A total of 61,232 cases met our inclusion criteria. Cardiac catheterization was performed during hospitalization in 78% of patients after an uncomplicated initial AMI. Age was inversely associated with receipt of cardiac catheterization: 85% of those < or =49 years old underwent catheterization compared with 63% of those > or =70 years old. Regression analysis revealed that use of catheterization was 2.9 times greater (95% confidence intervals 2.7 to 3.2) in patients < or =49 years old compared with those > or =70 years old. Geographic location and payor status also strongly influenced utilization of this procedure. In conclusion, routine coronary angiography after uncomplicated AMI is extensively utilized in all age groups, particularly in those <50 years of age. The efficacy and cost effectiveness of this strategy in these patients has not yet been determined in clinical trials.

RESUMO

BACKGROUND: Elevated serum cholesterol levels are associated with increased risk for acute myocardial infarction (AMI) and adverse patient outcomes. It is unclear what proportion of patients have their serum cholesterol levels measured during hospitalization for AMI and are given hypolipidemic therapy. OBJECTIVE: To examine decade-long trends in measurement of serum cholesterol levels during hospitalization for AMI and use of hypolipidemic therapy. METHODS: Observational study of 5204 residents of the Worcester, Mass, metropolitan area hospitalized with validated AMI in all greater Worcester hospitals in seven 1-year periods from 1986 through 1997. RESULTS: Increases in the measurement of serum cholesterol levels during hospitalization for AMI were observed between 1986 and 1991, followed by a progressive decrease; only 24% of patients with AMI in 1997 underwent cholesterol level testing. Younger age, male sex, and absence of a history of cardiovascular disease were associated with an increased likelihood measurement of serum cholesterol levels. Although the relative use of hypolipidemic therapy increased significantly over time (0.4% in 1986 vs 10.7% in 1997), the absolute rate of use remained low. In patients with elevated serum cholesterol levels (>/=6.2 mmol/L [>/=240 mg/dL]), 1.9% received hypolipidemic therapy in 1986 and 36.6% in 1997. CONCLUSIONS: These findings suggest recent declines in the assessment of total cholesterol levels in patients hospitalized with AMI. Although the use of hypolipidemic therapy during hospitalization for AMI has increased over time, considerable room for improvement remains.

RESUMO

OBJECTIVES: The goal of this study was to examine long-term trends in the incidence, in-hospital and long-term mortality patterns in patients with an initial non-Q-wave myocardial infarction (NQWMI) as compared with those with an initial Q-wave myocardial infarction (QWMI). BACKGROUND: Limited data are available describing trends in the incidence and mortality from an initial QWMI and NQWMI from a multi-hospital community-wide perspective. METHODS: Our study was an observational study of 5,832 metropolitan Worcester, Massachusetts residents (1990 census = 437,000) hospitalized with validated initial acute MI in all greater Worcester hospitals during 11 annual periods between 1975 and 1997. RESULTS: The incidence of QWMI progressively decreased between 1975/78 (incidence rate = 171/100,000 population) and 1997 (101/100,000 population). In contrast, the incidence of NQWMI progressively increased between 1975/78 (62/100,000 population) and 1997 (131/100,000 population). Hospital death rates were 19.5% for patients with QWMI and 12.5% for those with NQWMI. After controlling for various covariates, patients with QWMI remained at significantly increased risk for hospital mortality (adjusted odds ratio = 1.63; 95% confidence interval: 1.35, 1.97). While the hospital mortality of QWMI has progressively declined over time (1975/78 = 24%; 1997 = 14%), the in-hospital mortality for NQWMI has remained the same (1975/78 = 12%; 1997 = 12%). These trends remained after adjusting for potentially confounding prognostic factors. The multivariable adjusted two-year mortality after hospital discharge declined over time for patients with QWMI and NQWMI. CONCLUSIONS: Despite impressive declines in the incidence, in-hospital and long-term mortality associated with QWMI, NQWMI is increasing in frequency and has the same in-hospital mortality now as it did 22 years ago.

RESUMO

BACKGROUND: Cardiogenic shock complicating acute myocardial infarction (AMI) remains the leading cause of death in patients hospitalized with AMI. Although several studies have demonstrated the importance of establishing and maintaining a patent infarct-related artery, it remains unclear as to whether intra-aortic balloon counterpulsation (IABP) provides incremental benefit to reperfusion therapy. The purpose of this study was to determine whether IABP use is associated with lower in-hospital mortality rates in patients with AMI complicated by cardiogenic shock in a large AMI registry. METHODS: We evaluated patients participating in the National Registry of Myocardial Infarction 2 who had cardiogenic shock at initial examination or in whom cardiogenic shock developed during hospitalization (n = 23,180). RESULTS: The mean age of patients in the study was 72 years, 54% were men, and the majority were white. The overall mortality rate in all patients who had cardiogenic shock or in whom cardiogenic shock developed was 70%. IABP was used in 7268 (31%) patients. IABP use was associated with a significant reduction in mortality rates in patients who received thrombolytic therapy (67% vs 49%) but was not associated with any benefit in patients treated with primary angioplasty (45% vs 47%). In a multivariate model, the use of IABP in conjunction with thrombolytic therapy decreased the odds of death by 18% (odds ratio, 0.82; 95% confidence interval, 0.72 to 0.93). CONCLUSIONS: Patients with AMI complicated by cardiogenic shock may have substantial benefit from IABP when used in combination with thrombolytic therapy.

RESUMO

Psychiatry programs are facing significant business and financial challenges. This paper provides an overview of these management challenges in five areas: departmental, hospital, payment system, general finance, and policy. Psychiatric leaders will require skills in a variety of business management areas to ensure their program success. Many programs will need to develop new compensation models with more of an emphasis on revenue collection and overhead management. Programs which cannot master these areas are likely to go out of business. For academic programs, incentive systems must address not only clinical productivity, but academic and teaching output as well. General hospital programs will need to develop increased sophistication in differential cost accounting in order to be able to advocate for their patients and program in the current management climate. Clinical leaders will need the skills (ranging from actuarial to negotiations) to be at the table with contract development, since those decisions are inseparable from clinical care issues. Strategic planning needs to consider the value of improving integration with primary care, along with the ability to understand the advantages and disadvantages of risk-sharing models. Psychiatry leaders need to define and develop useful reports shared with clinical division leadership to track progress and identify problems and opportunities. Leaders should be responsible for a strategy for developing appropriate information system architecture and infrastructure. Finally, it is hoped that some leaders will emerge who can further our needs to address inequities in mental health fee schedules and parity issues which affect our program viability.

RESUMO

Hospital survival of patients with acute myocardial infarction (AMI) complicated by cardiogenic shock has improved during recent years. It is unclear whether this mortality benefit also applies to elderly patients with cardiogenic shock. Elderly residents (age > or = 65 years) of the Worcester, Massachusetts metropolitan area (1990 census population = 437,000) hospitalized with confirmed AMI and cardiogenic shock in all metropolitan Worcester, Massachusetts hospitals between 1986 and 1997 constituted the sample of interest. We examined the use of coronary reperfusion strategies, adjunctive therapy, and hospital mortality in a cohort of 166 cardiogenic patients treated early in the reperfusion era (1986 to 1991) compared with 144 patients with AMI treated approximately 1 decade later (1993 to 1997). There was a significant increase in the use of an early revascularization strategy over time (2% vs 16%, p <0.001). Marked increases in use of antiplatelet therapy, beta blockers, and angiotensin-converting enzyme inhibitors were also observed over the decade-long experience. In-hospital case fatality declined significantly over time, from 80% (1986 to 1991) to 69% (1993 to 1997) in elderly patients who developed cardiogenic shock (p = 0.03). After adjusting for differences in potentially confounding prognostic characteristics between patients hospitalized in the 2 study periods, an even more pronounced reduction in hospital mortality (42%) was observed for the most recently hospitalized cohort. The most powerful predictor of in-hospital survival was use of an early revascularization approach to treatment. Thus, hospital mortality has declined for patients > or = 65 years of age with AMI complicated by cardiogenic shock, and this decline has occurred in the setting of broader use of early revascularization and adjunctive medical therapy for this high-risk population.
