RESUMEN
BACKGROUND: An alternative patient-centered appointment-based cardiac rehabilitation (CR) program has led to significant improvements in health outcomes for patients with cardiovascular disease. However, less is known about the effects of this approach on health-related quality of life (HRQoL), particularly for women. OBJECTIVE: We examined the effects of a patient-centered appointment-based CR program on HRQoL by sex and examined predictors of HRQoL improvements specifically for women. METHODS: Data were used from an urban single-center CR program at Yale New Haven Health (2012-2017). We collected information on patient demographics, socioeconomic status, and clinical characteristics. The Outcome Short-Form General Health Survey (SF-36) was used to measure HRQoL. We evaluated sex differences in SF-36 scores using t tests and used a multivariate linear regression model to examine predictors of improvements in HRQoL (total SF-36 score) for women. RESULTS: A total of 1530 patients with cardiovascular disease (23.7% women, 4.8% Black; mean age, 64 ± 10.8 years) were enrolled in the CR program. Women were more likely to be older, Black, and separated, divorced, or widowed. Although women had lower total SF-36 scores on CR entry, there was no statistically significant difference in CR adherence or total SF-36 score improvements between sexes. Women who were employed and those with chronic obstructive pulmonary disease were more likely to have improvements in total SF-36 scores. CONCLUSION: Both men and women participating in an appointment-based CR program achieved significant improvements in HRQoL. This approach could be a viable alternative to conventional CR to optimize secondary outcomes for patients.
RESUMEN
Despite evidence-based guidelines,1 stroke rehabilitation remains underutilized, particularly among women and minorities.2 Telerehabilitation is a promising alternative to traditional in-person rehabilitation and offers a novel strategy to overcome access barriers,3 which intensified during the COVID-19 pandemic.4 A broadband connection is a prerequisite for its wide adoption but its availability varies across the United States (https://broadbandnow.com/national-broadband-map). Little is known about demographic and geographic variation in internet use among stroke survivors. In this study, we sought to compare internet use in a nationally representative sample of individuals with and without stroke.

AIMS: The prognosis of patients with MINOCA (myocardial infarction with non-obstructive coronary arteries) is poorly understood. We examined major adverse cardiac events (MACE) defined as all-cause mortality, re-hospitalization for acute myocardial infarction (AMI), heart failure (HF), or stroke 12-months post-AMI in patients with MINOCA versus AMI patients with obstructive coronary artery disease (MICAD). METHODS AND RESULTS: Multicentre, observational cohort study of patients with AMI (≥65 years) from the National Cardiovascular Data Registry CathPCI Registry (July 2009-December 2013) who underwent coronary angiography with linkage to the Centers for Medicare and Medicaid (CMS) claims data. Patients were classified as MICAD or MINOCA by the presence or absence of an epicardial vessel with ≥50% stenosis. The primary endpoint was MACE at 12 months, and secondary endpoints included the components of MACE over 12 months. Among 286 780 AMI admissions (276 522 unique patients), 16 849 (5.9%) had MINOCA. The 12-month rates of MACE (18.7% vs. 27.6%), mortality (12.3% vs. 16.7%), and re-hospitalization for AMI (1.3% vs. 6.1%) and HF (5.9% vs. 9.3%) were significantly lower for MINOCA vs. MICAD patients (P < 0.001), but was similar between MINOCA and MICAD patients for re-hospitalization for stroke (1.6% vs. 1.4%, P = 0.128). Following risk-adjustment, MINOCA patients had a 43% lower risk of MACE over 12 months (hazard ratio = 0.57, 95% confidence interval 0.55-0.59), in comparison to MICAD patients. This pattern was similar for adjusted risks of the MACE components. CONCLUSION: This study confirms an unfavourable prognosis in elderly patients with MINOCA undergoing coronary angiography, with one in five patients with MINOCA suffering a major adverse event over 12 months.

BACKGROUND: Recovery from acute myocardial infarction (AMI) has been primarily understood in a narrow medical sense. For patients who survive, secondary prevention focuses largely on enhancing clinical outcomes. As a result, there is a lack of descriptive accounts of patients' experiences after AMI and little is known about how people go about the challenge of recovering from such an event. OBJECTIVE: We conducted a meta-synthesis of the available literature on qualitative accounts of patients' experiences after AMI. METHODS: We searched for relevant papers that were descriptive, qualitative accounts of participants' experiences after AMI across 4 electronic databases (April 2016). Using an adapted meta-ethnography approach, we analyzed the findings by translating studies into one another and synthesizing the findings from the studies. RESULTS: After a review of titles/abstracts, reading each article twice in full, and cross-referencing articles, this process resulted in 17 studies with 224 participants (48% women) aged 23 to 90 years. All participants provided a first-person account of an AMI within the 3-day to 25-year time frame. Two major themes emerged that characterized patients' experiences: navigating lifestyle changes and navigating the emotional reaction to the event-consisting of various subthemes. CONCLUSION: Although AMI tends to be seen as a discrete event, participants are left with little professional guidance as to how to negotiate significant, and often discordant, psychosocial changes that have long-lasting effects on their lives, similar to persons with chronic illnesses but without research in place to figure out how to best support them.

PURPOSE OF REVIEW: To explain sex and gender approaches to studying acute myocardial infarction (AMI) risk and outcomes in younger women (18-55 years). More specifically, by looking at the AMI care pathway-from AMI risk to receiving acute and follow-up outpatient care to longer term AMI outcomes-we will examine where potential psychosocial factors may be associated with inequalities in AMI care and outcomes in younger women. RECENT FINDINGS: Despite recent declines in AMI incidence, morbidity, and mortality rates, younger women stand out as a group whose incidence has risen and who face worse outcomes following AMI, as compared with other groups. A focus on gender, rather than the binary, biological sex construct, allowed researchers to better understand potential pathways as to why younger women are facing this risk. Feminine traits and disproportionate exposures to psychosocial stressors in society at large may be correlated with inequalities in AMI care and further AMI outcomes in younger women. Psychosocial interventions in women with AMI that have proven to be successful have embraced this wider gender concept. Adopting a wider gender-concept to understand roles and demands that are placed on individuals that make them more at risk to experience psychosocial stressors and make it more challenging to organize self-care, get access to care, and equitable care may be needed.

BACKGROUND: Compared with men, women are at higher risk of rehospitalization in the first month after discharge for acute myocardial infarction (AMI). However, it is unknown whether this risk extends to the full year and varies by age. Explanatory factors potentially mediating the relationship between sex and rehospitalization remain unexplored and are needed to reduce readmissions. The aim of this study was to assess sex differences and factors associated with 1-year rehospitalization rates after AMI. METHODS: We recruited 3536 patients (33% women) ≥18 years of age hospitalized with AMI from 24 US centers into the TRIUMPH study (Translational Research Investigating Underlying Disparities in Acute Myocardial Infarction Patients' Health Status). Data were obtained by medical record abstraction and patient interviews, and a physician panel adjudicated hospitalizations within the first year after AMI. We compared sex differences in rehospitalization using a Cox proportional hazards model, following sequential adjustment for covariates and testing for an age-sex interaction. RESULTS: One-year crude all-cause rehospitalization rates for women were significantly higher than men after AMI (hazard ratio, 1.29 for women; 95% confidence interval, 1.12-1.48). After adjustment for demographics and clinical factors, women had a persistent 26% higher risk of rehospitalization (hazard ratio, 1.26; 95% confidence interval, 1.08-1.47). However, after adjustment for health status and psychosocial factors (hazard ratio, 1.14; 95% confidence interval, 0.96-1.35), the association was attenuated. No significant age-sex interaction was found for 1-year rehospitalization, suggesting that the increased risk applied to both older and younger women. CONCLUSIONS: Regardless of age, women have a higher risk of rehospitalization compared with men over the first year after AMI. Although the increased risk persisted after adjustment for clinical factors, the poorer health and psychosocial state of women attenuated the difference.

BACKGROUND: Young women with acute myocardial infarction (AMI) have higher mortality risk than similarly aged men. An adverse lipid profile is an important risk factor for cardiovascular outcomes after AMI, but little is known about whether young women with AMI have a higher-risk lipid pattern than men. We characterized sex differences in lipid profiles and treatment utilization among young adults with AMI. METHODS: A total of 2,219 adults with AMI (1,494 women) aged 18-55 years were enrolled from 103 hospitals in the United States (2008-2012). Serum lipids and lipoprotein subclasses were measured 1 month after discharge. RESULTS: More than 90% of adults were discharged on a statin, but less than half received a high-intensity dose and 12% stopped taking treatments by 1 month. For both men and women, the median of low-density lipoprotein (LDL) cholesterol was reduced to <100 mg/dL 1 month after discharge for AMI, but high-density lipoprotein (HDL) cholesterol remained <40 mg/dL. Multivariate regression analyses showed that young women had favorable lipoprotein profiles compared with men: women had higher HDL cholesterol and HDL large particle, but lower total cholesterol-to-HDL cholesterol ratio and LDL small particle. CONCLUSIONS: Young women with AMI had slightly favorable lipid and lipoprotein profiles compared with men, suggesting that difference in lipid and lipoprotein may not be a major contributor to sex differences in outcomes after AMI. In both men and women, statin remained inadequately used, and low HDL cholesterol level was a major lipid abnormality.

OBJECTIVE: The aim of the study was to examine how psychological stress changes over time in young and middle-aged patients after experiencing an acute myocardial infarction (AMI) and whether these changes differ between men and women. METHODS: We analyzed data obtained from 2358 women and 1151 men aged 18 to 55 years hospitalized for AMI. Psychological stress was measured using the 14-item Perceived Stress Scale (PSS-14) at initial hospitalization and at 1 month and 12 months after AMI. We used linear mixed-effects models to examine changes in PSS-14 scores over time and sex differences in these changes, while adjusting for patient characteristics and accounting for correlation among repeated observations within patients. RESULTS: Overall, patients' perceived stress decreased over time, especially during the first month after AMI. Women had higher levels of perceived stress than men throughout the 12-month period (difference in PSS-14 score = 3.63, 95% confidence interval = 3.08 to 4.18, p < .001), but they did not differ in how stress changed over time. Adjustment for patient characteristics did not alter the overall pattern of sex difference in changes of perceived stress over time other than attenuating the magnitude of sex difference in PSS-14 score (difference between women and men = 1.74, 95% confidence interval = 1.32 to 2.16, p < .001). The magnitude of sex differences in perceived stress was similar in patients with versus without post-AMI angina, even though patients with angina experienced less improvement in PSS-14 score than those without angina. CONCLUSIONS: In young and middle-aged patients with AMI, women reported higher levels of perceived stress than men throughout the first 12 months of recovery. However, women and men had a similar pattern in how perceived stress changed over time.

BACKGROUND: Long-term nonfatal outcomes after implantable cardioverter-defibrillator (ICD) placement are poorly defined. OBJECTIVE: To determine the long-term risk for ICD-related complications requiring reoperation or hospitalization and reoperation for reasons other than complications, and to assess associated patient and device characteristics. DESIGN: Observational cohort study of ICD implantations from the National Cardiovascular Data Registry ICD registry linked with Medicare fee-for-service claims data. SETTING: 1437 U.S. hospitals. PATIENTS: 114 484 patients aged 65 years or older (mean, 74.8 years [SD, 6.2]; 72.4% male) receiving an ICD for the first time from 2006 to 2010 (single-chamber, 19.8%; dual-chamber, 41.3%; cardiac resynchronization therapy with a defibrillator [CRT-D], 38.9%). MEASUREMENTS: Rate and cumulative incidence of ICD-related complications requiring reoperation or hospitalization and reoperation for reasons other than complications. RESULTS: During a median follow-up of 2.7 years (interquartile range, 1.8 to 3.9 years), 40 072 patients died, representing 12.6 (95% CI, 12.5 to 12.7) deaths per 100 patient-years of follow-up. When the risk for death was accounted for, there were 6.1 (CI, 6.0 to 6.2) ICD-related complications per 100 patient-years that required reoperation or hospitalization and 3.9 (CI, 3.8 to 4.0) reoperations per 100 patient-years for reasons other than complications. Overall, 10 patients had complications or reoperation per 100 patient-years of follow-up. Younger age at implantation (65 to 69 vs. >85 years) (hazard ratio [HR], 1.55 [CI, 1.43 to 1.69]), receipt of a CRT-D device (HR, 1.38 [CI, 1.31 to 1.45]) versus a single-chamber device, female sex (HR, 1.16 [CI, 1.12 to 1.21]), and black race (HR, 1.14 [CI, 1.05 to 1.23]) were associated with the greatest increased risks for ICD-related complications. LIMITATION: The analysis was limited to Medicare fee-for-service patients aged 65 years or older. CONCLUSION: Patients have a high rate of device-related complications and reoperation for other causes after ICD implantation. Risks of ICD implantation and strategies to reduce them should be actively considered before implantation.

RESUMEN
BACKGROUND: Myocardial infarction with nonobstructive coronary arteries (MINOCA) is a puzzling clinical entity with no previous evaluation of the literature. This systematic review aims to (1) quantify the prevalence, risk factors, and 12-month prognosis in patients with MINOCA, and (2) evaluate potential pathophysiological mechanisms underlying this disorder. METHODS AND RESULTS: Quantitative assessment of 28 publications using a meta-analytic approach evaluated the prevalence, clinical features, and prognosis of MINOCA. The prevalence of MINOCA was 6% [95% confidence interval, 5%-7%] with a median patient age of 55 years (95% confidence interval, 51-59 years) and 40% women. However, in comparison with those with myocardial infarction associated with obstructive coronary artery disease, the patients with MINOCA were more likely to be younger and female but less likely to have hyperlipidemia, although other cardiovascular risk factors were similar. All-cause mortality at 12 months was lower in MINOCA (4.7%; 95% confidence interval, 2.6%-6.9%) compared with myocardial infarction associated with obstructive coronary artery disease (6.7%, 95% confidence interval, 4.3%-9.0%). Qualitative assessment of 46 publications evaluating the underlying pathophysiology responsible for MINOCA revealed the presence of a typical myocardial infarct on cardiac magnetic resonance imaging in only 24% of patients, with myocarditis occurring in 33% and no significant abnormality in 26%. Coronary artery spasm was inducible in 27% of MINOCA patients, and thrombophilia disorders were detected in 14%. CONCLUSIONS: MINOCA should be considered as a working diagnosis with multiple potential causes that require evaluation so that directed therapies may improve its guarded prognosis.

BACKGROUND: Young women (<65 years) experience a 2- to 3-fold greater mortality risk than younger men after an acute myocardial infarction. However, it is unknown whether they are at higher risk for 30-day readmission, and if this association varies by age. We examined sex differences in the rate, timing, and principal diagnoses of 30-day readmissions, including the independent effect of sex following adjustment for confounders. METHODS AND RESULTS: We included patients aged 18 to 64 years with a principal diagnosis of acute myocardial infarction. Data were used from the Healthcare Cost and Utilization Project-State Inpatient Database for California (07-09). Readmission diagnoses were categorized by using an aggregated version of the Centers for Medicare and Medicaid Services' Condition Categories, and readmission timing was determined from the day after discharge. Of 42,518 younger patients with acute myocardial infarction (26.4% female), 4775 (11.2%) had at least 1 readmission. The 30-day all-cause readmission rate was higher for women (15.5% versus 9.7%, P<0.0001). For both sexes, readmission risk was highest on days 2 to 4 after discharge and declined thereafter, and women were more likely to present with noncardiac diagnoses (44.4% versus 40.6%, P=0.01). Female sex was associated with a higher rate of 30-day readmission, which persisted after adjustment (hazard ratio, 1.22; 95% confidence interval, 1.15-1.30). There was no significant interaction between age and sex on readmission. CONCLUSIONS: In comparison with men, younger women have a higher risk for readmission, even after the adjustment for confounders. The timing of 30-day readmission was similar in women and men, and both sexes were susceptible to a wide range of causes for readmission.

BACKGROUND: Despite the excess risk of mortality in young women (≤55 years of age) after acute myocardial infarction (AMI), little is known about young women's health status (symptoms, functioning, quality of life) during the first year of recovery after an AMI. We examined gender differences in health status over time from baseline to 12 months after AMI. METHODS AND RESULTS: A total of 3501 AMI patients (67% women) 18 to 55 years of age were enrolled from 103 US and 24 Spanish hospitals. Data were obtained by medical record abstraction and patient interviews at baseline hospitalization and 1 and 12 months after AMI. Health status was measured by generic (Short Form-12) and disease-specific (Seattle Angina Questionnaire) measures. We compared health status scores at all 3 time points and used longitudinal linear mixed-effects analyses to examine the independent effect of gender, adjusting for time and selected covariates. Women had significantly lower health status scores than men at each assessment (all P values <0.0001). After adjustment for time and all covariates, women had Short Form-12 physical/mental summary scores that were -0.96 (95% confidence interval [CI], -1.59 to -0.32) and -2.36 points (95% CI, -2.99 to -1.73) lower than those of men, as well as worse Seattle Angina Questionnaire physical limitations (-2.44 points lower; 95% CI, -3.53 to -1.34), more angina (-1.03 points lower; 95% CI, -1.98 to -0.07), and poorer quality of life (-3.51 points lower; 95% CI, -4.80 to -2.22). CONCLUSION: Although both genders recover similarly after AMI, women have poorer scores than men on all health status measures, a difference that persisted throughout the entire year after discharge.

BACKGROUND: Sex disparities in reperfusion therapy for patients with acute ST-segment-elevation myocardial infarction have been documented. However, little is known about whether these patterns exist in the comparison of young women with men. METHODS AND RESULTS: We examined sex differences in rates, types of reperfusion therapy, and proportion of patients exceeding American Heart Association reperfusion time guidelines for ST-segment-elevation myocardial infarction in a prospective observational cohort study (2008-2012) of 1465 patients 18 to 55 years of age, as part of the US Variations in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO) study at 103 hospitals enrolling in a 2:1 ratio of women to men. Of the 1238 patients eligible for reperfusion, women were more likely to be untreated than men (9% versus 4%, P=0.002). There was no difference in reperfusion strategy for the 695 women and 458 men treated. Women were more likely to exceed in-hospital and transfer time guidelines for percutaneous coronary intervention than men (41% versus 29%; odds ratio, 1.65; 95% confidence interval, 1.27-2.16), more so when transferred (67% versus 44%; odds ratio, 2.63; 95% confidence interval, 1.17-4.07); and more likely to exceed door-to-needle times (67% versus 37%; odds ratio, 2.62; 95% confidence interval, 1.23-2.18). After adjustment for sociodemographic, clinical, and organizational factors, sex remained an important factor in exceeding reperfusion guidelines (odds ratio, 1.72; 95% confidence interval, 1.28-2.33). CONCLUSIONS: Young women with ST-segment-elevation myocardial infarction are less likely to receive reperfusion therapy and more likely to have reperfusion delays than similarly aged men. Sex disparities are more pronounced among patients transferred to percutaneous coronary intervention institutions or who received fibrinolytic therapy.

BACKGROUND: Current classification schemes for acute myocardial infarction (AMI) may not accommodate the breadth of clinical phenotypes in young women. METHODS AND RESULTS: We developed a novel taxonomy among young adults (≤55 years) with AMI enrolled in the Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO) study. We first classified a subset of patients (n=600) according to the Third Universal Definition of MI using a structured abstraction tool. There was heterogeneity within type 2 AMI, and 54 patients (9%; including 51 of 412 women) were unclassified. Using an inductive approach, we iteratively grouped patients with shared clinical characteristics, with the aims of developing a more inclusive taxonomy that could distinguish unique clinical phenotypes. The final VIRGO taxonomy classified 2802 study participants as follows: class 1, plaque-mediated culprit lesion (82.5% of women; 94.9% of men); class 2, obstructive coronary artery disease with supply-demand mismatch (2a: 1.4% women; 0.9% men) and without supply-demand mismatch (2b: 2.4% women; 1.1% men); class 3, nonobstructive coronary artery disease with supply-demand mismatch (3a: 4.3% women; 0.8% men) and without supply-demand mismatch (3b: 7.0% women; 1.9% men); class 4, other identifiable mechanism (spontaneous dissection, vasospasm, embolism; 1.5% women, 0.2% men); and class 5, undetermined classification (0.8% women, 0.2% men). CONCLUSIONS: Approximately 1 in 8 young women with AMI is unclassified by the Universal Definition of MI. We propose a more inclusive taxonomy that could serve as a framework for understanding biological disease mechanisms, therapeutic efficacy, and prognosis in this population.

BACKGROUND: The number of percutaneous coronary interventions (PCI) in China has increased more than 20-fold over the last decade. Consequently, there is a need for national-level information to characterize PCI indications and long-term patient outcomes, including health status, to understand and improve evolving practice patterns. OBJECTIVES: This nationwide prospective study of patients receiving PCI is to: (1) measure long-term clinical outcomes (including death, acute myocardial infarction [AMI], and/or revascularization), patient-reported outcomes (PROs), cardiovascular risk factor control and adherence to medications for secondary prevention; (2) determine patient- and hospital-level factors associated with care process and outcomes; and (3) assess the appropriateness of PCI procedures. METHODS: The China Patient-centered Evaluative Assessment of Cardiac Events (PEACE) Prospective Study of PCI has enrolled 5,000 consecutive patients during 2012-2014 from 34 diverse hospitals across China undergoing PCI for any indication. We abstracted details of patient's medical history, treatments, and in-hospital outcomes from medical charts, and conducted baseline, 1-, 6-, and 12-month interviews to characterize patient demographics, risk factors, clinical presentation, healthcare utilization, and health status using validated PRO measures. The primary outcome, a composite measure of death, AMI and/or revascularization, as well as PROs, medication adherence and cardiovascular risk factor control, was assessed throughout the 12-month follow-up. Blood and urine samples were collected at baseline and 12 months and stored for future analyses. To validate reports of coronary anatomy, 2,000 angiograms are randomly selected and read by two independent core laboratories. Hospital characteristics regarding their facilities, processes and organizational characteristics are assessed by site surveys. CONCLUSION: China PEACE Prospective Study of PCI will be the first study to generate novel, high-quality, comprehensive national data on patients' socio-demographic, clinical, treatment, and metabolic/genetic factors, and importantly, their long-term outcomes following PCI, including health status. This will build the foundation for PCI performance improvement efforts in China. © 2016 The Authors. Catheterization and Cardiovascular Interventions. Published by Wiley Periodicals, Inc.

PURPOSE: Interpreting the clinical significance of changes in patient-reported outcomes (PROs) is critically important. The most commonly used approach is to anchor mean changes on PRO scores against a global assessment of change. Whether the assessor of global change should be patients or their physicians is unknown. We compared patients' and physicians' assessments of change over time to examine which was more aligned with patients' changes in PRO measures. METHODS: A total of 459 chronic heart failure patients aged >30 years were enrolled from 13 US centers. Data were obtained by medical record abstraction, physical assessments, and patient interviews at a baseline clinic visit and 6 weeks later. Health status was measured with the disease-specific Kansas City Cardiomyopathy Questionnaire (KCCQ), and both patients and physicians completed a validated 15-level global assessment of change, ranging from large deterioration to large improvement. RESULTS: There was substantial variation between physicians/patients' global assessment of clinical change (weighted kappa = 0.36, 95 % CI 0.28, 0.43). Overall, physician assessments were more strongly correlated with change on the KCCQ summary score than were patients' assessments (physician R = 0.37, patient R = 0.29). CONCLUSION: There was substantial variation between patients' and physicians' global assessment of 6-week change in heart failure status. Physician assessments of the importance of clinical changes were more strongly associated with changes in all domains of patient-reported health status, as assessed by the KCCQ, and may provide a more consistent method for defining the clinical importance of changes in patients' health status.

BACKGROUND AND PURPOSE: There are no contemporary national-level data on Emergency Medical Services (EMS) response times for suspected stroke in the United States (US). Because effective stroke treatment is time-dependent, we characterized response times for suspected stroke, and examined whether they met guideline recommendations. METHODS: Using the National EMS Information System dataset, we included 911 calls for patients ≥ 18 years with an EMS provider impression of stroke. We examined variation in the total EMS response time by dispatch notification of stroke, age, sex, race, region, time of day, day of the week, as well as the proportion of EMS responses that met guideline recommended response times. Total EMS response time included call center dispatch time (receipt of call by dispatch to EMS being notified), EMS dispatch time (dispatch informing EMS to EMS starts moving), time to scene (EMS starts moving to EMS arrival on scene), time on scene (EMS arrival on scene to EMS leaving scene), and transport time (EMS leaving scene to reaching treatment facility). RESULTS: We identified 184,179 events with primary impressions of stroke (mean age 70.4 ± 16.4 years, 55% male). Median total EMS response time was 36 (IQR 28.7-48.0) minutes. Longer response times were observed for patients aged 65-74 years, of white race, females, and from non-urban areas. Dispatch identification of stroke versus "other" was associated with marginally faster response times (36.0 versus 36.7 minutes, p < 0.01). When compared to recommended guidelines, 78% of EMS responses met dispatch delay of <1 minute, 72% met time to scene of <8 minutes, and 46% met on-scene time of <15 minutes. CONCLUSIONS: In the United States, time from receipt of 9-1-1 calls to treatment center arrival takes a median of 36 minutes for stroke patients, an improvement upon previously published times. The fact that 22%-46% of EMS responses did not meet stroke guidelines highlights an opportunity for improvement. Future studies should examine EMS diagnostic accuracy nationally or regionally using outcomes based approaches, as accurate recognition of prehospital strokes is vital in order to improve response times, adhere to guidelines, and ultimately provide timely and effective stroke treatment.

BACKGROUND: Studies of sex differences in long-term mortality after acute myocardial infarction have reported mixed results. A systematic review is needed to characterize what is known about sex differences in long-term outcomes and to define gaps in knowledge. METHODS AND RESULTS: We searched the Medline database from 1966 to December 2012 to identify all studies that provided sex-based comparisons of mortality after acute myocardial infarction. Only studies with at least 5 years of follow-up were reviewed. Of the 1877 identified abstracts, 52 studies met the inclusion criteria, of which 39 were included in this review. Most studies included fewer than one-third women. There was significant heterogeneity across studies in patient populations, methodology, and risk adjustment, which produced substantial variability in risk estimates. In general, most studies reported higher unadjusted mortality for women compared with men at both 5 and 10 years after acute myocardial infarction; however, many of the differences in mortality became attenuated after adjustment for age. Multivariable models varied between studies; however, most reported a further reduction in sex differences after adjustment for covariates other than age. Few studies examined sex-by-age interactions; however, several studies reported interactions between sex and treatment whereby women have similar mortality risk as men after revascularization. CONCLUSIONS: Sex differences in long-term mortality after acute myocardial infarction are largely explained by differences in age, comorbidities, and treatment use between women and men. Future research should aim to clarify how these differences in risk factors and presentation contribute to the sex gap in mortality.

INTRODUCTION: Despite evidence supporting the benefits of marriage on cardiovascular health, the impact of marital/partner status on the long-term readmission of young acute myocardial infarction (AMI) survivors is less clear. We examined the association between marital/partner status and 1-year all-cause readmission and explored sex differences among young AMI survivors. METHODS: Data were from the VIRGO study (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients), which enrolled young adults aged 18-55 years with AMI (2008-2012). The primary end point was all-cause readmission within 1 year of hospital discharge, obtained from medical records and patient interviews and adjudicated by a physician panel. We performed Cox proportional hazards models with sequential adjustment for demographic, socioeconomic, clinical, and psychosocial factors. Sex-marital/partner status interaction was also tested. RESULTS: Of the 2,979 adults with AMI (2002 women [67.2%]; mean age 48 [interquartile range, 44-52] years), unpartnered individuals were more likely to experience all-cause readmissions compared with married/partnered individuals within the first year after hospital discharge (34.6% versus 27.2%, hazard ratio [HR] = 1.31; 95% confidence interval [CI], 1.15-1.49). The association attenuated but remained significant after adjustment for demographic and socioeconomic factors (adjusted HR, 1.16; 95% CI, 1.01-1.34), and it was not significant after further adjusting for clinical factors and psychosocial factors (adjusted HR, 1.10; 95%CI, 0.94-1.28). A sex-marital/partner status interaction was not significant (p = 0.69). Sensitivity analysis using data with multiple imputation and restricting outcomes to cardiac readmission yielded comparable results. CONCLUSIONS: In a cohort of young adults aged 18-55 years, unpartnered status was associated with 1.3-fold increased risk of all-cause readmission within 1 year of AMI discharge. Further adjustment for demographic, socioeconomic, clinical, and psychosocial factors attenuated the association, suggesting that these factors may explain disparities in readmission between married/partnered versus unpartnered young adults. Whereas young women experienced more readmission compared to similar-aged men, the association between marital/partner status and 1-year readmission did not vary by sex.
