Time to Standardize and Broaden the Criteria of Acute Coronary Syndrome Symptom Presentations in Women

Myocardial Infarction Within 30 Days of Discharge From an Emergency Department: A Descriptive Study of Albertan Women

Background

Cardiovascular diseases (CVDs) are the leading cause of premature death for Canadian women, which may be due partly to a lack of awareness of the presentation of acute coronary events in emergency departments (EDs). To address an identified gap in women's cardiovascular care, we sought to describe the clinical and comorbid factors of women who, following discharge from an ED, suffered a myocardial infarction (MI).

Methods

Descriptive analyses were completed on a cohort of women who presented to an ED in Alberta, Canada, between January 1, 2010 and December 31, 2020, were discharged, and within 30 days of their index ED visit, were admitted to the hospital with an MI. The cohort was explored for clinical and comorbid data, ED visits pre-MI, type of MI, and presenting complaint/ primary diagnosis for the index ED visit.

Results

1380 women were included in this analysis with a mean age of 67 (standard deviation ±13) years. The frequencies of hypertension, diabetes, and dyslipidemia among the youngest women, aged 18-45 years, were 47.5%, 31.3%, and 48.8%, respectively. Women across all ages demonstrated a high prevalence of traditional CVD risk factors, and 22% of women presented to an ED 2 or more times within the 30 days pre-MI.

Conclusions

Regardless of their age, the women in this cohort had notable CVD risk factors. Future research is required to better understand the phenomenon of women presenting multiple times to an ED pre-MI. Research is needed on life-stage-specific factors of women presenting to EDs pre-MI, to help reduce MI incidence.

Community- and Patient-Partner Engagement in Women's Cardiovascular Disease Research: A Rapid Review of the Evidence

The primary objective of this rapid review is to describe community-partner and patient-partner engagement in women's cardiovascular disease (CVD) research. Secondary objectives are to: (i) describe the phase of the research in which community and patient partners were engaged; (ii) define the level of engagement at each research phase; and (iii) make recommendations for future engagement of community and/or patient partners in women's CVD research. Rapid review guidelines recommended by the Cochrane Rapid Reviews Methods Group and Tricco et al. were used to search 5 databases using medical subject headings (MeSH) and/or keywords. Participants included women (cis and trans) aged > 18 years who had ischemic heart disease, heart failure, or stroke. A risk of bias assessment was not undertaken. Findings are summarized and/or clustered as community-based participatory research, or patient-oriented and/or patient-partner research. Our search yielded 39,998 titles and abstracts. Of these, 35 were included in a final narrative synthesis, comprising data from 474 community and/or patient partners, including 417 (88%) women. Over 85% of community partners collaborated in the design and/or planning and implementation of women's CVD research; most originated in the US; only one originated in Canada. Most patient-oriented and patient-partner research originated in Canada. However, less than 50% of patient partners collaborated in any phase of research. Sex, gender, race, and ethnicity were rarely reported. Results suggest negligible community and inadequate patient-oriented and/or patient-partner engagement in women's CVD research in Canada. Improved CVD outcomes for women may be achieved with better community- and patient-partner collaboration across all phases of research, genders, race, and ethnicities.

Why do women with cardiac symptoms delay seeking medical help? Insights from a qualitative study among Jewish Israeli women

BACKGROUND

The delay time from onset of symptoms of a myocardial infarction to seeking medical assistance can have life-threatening consequences. Women delay significantly more often than men do in calling for medical help, once symptoms of a myocardial infarction occur.

OBJECTIVES

The current qualitative study's main aim was to explore psychosocial factors that contribute to Israeli women's delaying calls for medical assistance and, by contrast, the motivational factors that encourage them to do so.

DESIGN

A qualitative study.

METHOD

In total, 12 women were interviewed shortly after experiencing a myocardial infarction. Qualitative data were subjected to thematic analysis.

RESULTS

Two major themes emerged describing barriers to seeking help: (1) the use of denial as a defense mechanism and (2) the need for control. The motivational factor which enhanced help-seeking was "fear of death."

CONCLUSION

These findings may help in designing gender-sensitive interventions with the aim of minimizing the symptom onset to call time and thus preventing irreversible and life-threatening health damage.

Atypical Chest Pain in a Patient With Breast Implant

Breast implant surgery typically improves patient breast satisfaction and health-related quality of life. However, breast implants are also linked to long-term local problems like capsular contracture and breast discomfort. Chest pain is one of the reasons that patients with breast implants seek consultations, which is not typically attributable to cardiovascular reasons. The potential reasons for atypical chest pain are diverse. The absence of a precise diagnosis may also result in incorrect examinations and management, leading to further worry and wasted work time. A 55-year-old woman with a breast implant 10 years prior to the incident, presented with atypical chest pain on and off for a year and was treated as a case of unstable angina, costochondritis, and vasospastic spasm. Despite multiple visits, her symptoms did not resolve. Later, the patient presented with a lump over the left breast, associated with constitutional symptoms. Examination revealed a left breast implant with capsular contracture grade III, and ultrasonography showed signs of a ruptured implant. Symptoms eventually resolved after the removal of the breast implant.

A Survey of Female-Specific Cardiovascular Protocols in Emergency Departments in Canada

Background

Cardiovascular diseases (CVD) remain the leading cause of death for women. However, systematic inequalities exist in how women experience clinical cardiovascular (CV) policies, programs, and initiatives.

Methods

In collaboration with the Heart and Stroke Foundation of Canada, a question regarding female-specific CV protocols in an emergency department (ED), or an inpatient or ambulatory care area of a healthcare site was sent via e-mail to 450 healthcare sites in Canada. Contacts at these sites were established through the larger initiative-the Heart Failure Resources and Services Inventory-conducted by the foundation.

Results

Responses were received from 282 healthcare sites, with 3 sites confirming the use of a component of a female-specific CV protocol in the ED. Three sites noted using sex-specific troponin levels in the diagnosis of acute coronary syndromes; 2 of the sites are participants in the hs-cTn-Optimizing the Diagnosis of Acute Myocardial Infarction/Injury in Women (CODE MI) trial. One site reported the integration of a female-specific CV protocol component into routine use.

Conclusions

We have identified an absence of female-specific CVD protocols in EDs that may be associated with the identified poorer outcomes in women impacted by CVD. Female-specific CV protocols may serve to increase equity and ensure that women with CV concerns have access to the appropriate care in a timely manner, thereby helping to mitigate some of the current adverse effects experienced by women who present to Canadian EDs with CV symptoms.

The Canadian Women's Heart Health Alliance Atlas on the Epidemiology, Diagnosis, and Management of Cardiovascular Disease in Women - Chapter 6: Sex- and Gender-Specific Diagnosis and Treatment

This chapter summarizes the sex- and gender-specific diagnosis and treatment of acute/unstable presentations and nacute/stable presentations of cardiovascular disease in women. Guidelines, scientific statements, systematic reviews/meta-analyses, and primary research studies related to diagnosis and treatment of coronary artery disease, cerebrovascular disease (stroke), valvular heart disease, and heart failure in women were reviewed. The evidence is summarized as a narrative, and when available, sex- and gender-specific practice and research recommendations are provided. Acute coronary syndrome presentations and emergency department delays are different in women than they are in men. Coronary angiography remains the gold-standard test for diagnosis of obstructive coronary artery disease. Other diagnostic imaging modalities for ischemic heart disease detection (eg, positron emission tomography, echocardiography, single-photon emission computed tomography, cardiovascular magnetic resonance, coronary computed tomography angiography) have been shown to be useful in women, with their selection dependent upon both the goal of the individualized assessment and the testing resources available. Noncontrast computed tomography and computed tomography angiography are used to diagnose stroke in women. Although sex-specific differences appear to exist in the efficacy of standard treatments for diverse presentations of acute coronary syndrome, many cardiovascular drugs and interventions tested in clinical trials were not powered to detect sex-specific differences, and knowledge gaps remain. Similarly, although knowledge is evolving about sex-specific difference in the management of valvular heart disease, and heart failure with both reduced and preserved ejection fraction, current guidelines are lacking in sex-specific recommendations, and more research is needed.

Sex and Race Differences in the Evaluation and Treatment of Young Adults Presenting to the Emergency Department With Chest Pain

Background Acute myocardial infarctions are increasingly common among young adults. We investigated sex and racial differences in the evaluation of chest pain (CP) among young adults presenting to the emergency department. Methods and Results Emergency department visits for adults aged 18 to 55 years presenting with CP were identified in the National Hospital Ambulatory Medical Care Survey 2014 to 2018, which uses stratified sampling to produce national estimates. We evaluated associations between sex, race, and CP management before and after multivariable adjustment. We identified 4152 records representing 29 730 145 visits for CP among young adults. Women were less likely than men to be triaged as emergent (19.1% versus 23.3%, respectively, P<0.001), to undergo electrocardiography (74.2% versus 78.8%, respectively, P=0.024), or to be admitted to the hospital or observation unit (12.4% versus 17.9%, respectively, P<0.001), but ordering of cardiac biomarkers was similar. After multivariable adjustment, men were seen more quickly (hazard ratio [HR], 1.15 [95% CI, 1.05-1.26]) and were more likely to be admitted (adjusted odds ratio, 1.40 [95% CI, 1.08-1.81]; P=0.011). People of color waited longer for physician evaluation (HR, 0.82 [95% CI, 0.73-0.93]; P<0.001) than White adults after multivariable adjustment, but there were no racial differences in hospital admission, triage level, electrocardiography, or cardiac biomarker testing. Acute myocardial infarction was diagnosed in 1.4% of adults in the emergency department and 6.5% of admitted adults. Conclusions Women and people of color with CP waited longer to be seen by physicians, independent of clinical features. Women were independently less likely to be admitted when presenting with CP. These differences could impact downstream treatment and outcomes.

The Canadian Women's Heart Health Alliance Atlas on the Epidemiology, Diagnosis, and Management of Cardiovascular Disease in Women - Chapter 5: Sex- and Gender-Unique Manifestations of Cardiovascular Disease

This Atlas chapter summarizes sex- and some gender-associated, and unique aspects and manifestations of cardiovascular disease (CVD) in women. CVD is the primary cause of premature death in women in Canada and numerous sex-specific differences related to symptoms and pathophysiology exist. A review of the literature was done to identify sex-specific differences in symptoms, pathophysiology, and unique manifestations of CVD in women. Although women with ischemic heart disease might present with chest pain, the description of symptoms, delay between symptom onset and seeking medical attention, and prodromal symptoms are often different in women, compared with men. Nonatherosclerotic causes of angina and myocardial infarction, such as spontaneous coronary artery dissection are predominantly identified in women. Obstructive and nonobstructive coronary artery disease, aortic aneurysmal disease, and peripheral artery disease have worse outcomes in women compared with men. Sex differences exist in valvular heart disease and cardiomyopathies. Heart failure with preserved ejection fraction is more often diagnosed in women, who experience better survival after a heart failure diagnosis. Stroke might occur across the lifespan in women, who are at higher risk of stroke-related disability and age-specific mortality. Sex- and gender-unique differences exist in symptoms and pathophysiology of CVD in women. These differences must be considered when evaluating CVD manifestations, because they affect management and prognosis of cardiovascular conditions in women.

“Her Heart Matters”—Making Visible the Cardiac Pain Experiences of Women with Physical Disabilities and Heart Disease: A Qualitative Study

Background

Women with physical disabilities are faced with challenges in many aspects of life—education, work, income, relationships, as well as their general health. These women are at a greater risk of developing heart disease. This study aimed to explore the cardiac pain experiences of women with physical disabilities and heart disease within a Canadian healthcare context.

Methods

In this qualitative study, 8 women with physical disabilities and heart disease from across Canada were interviewed. They were asked about their pre-, peri-, and post-diagnostic experiences in the Canadian healthcare system. Transcripts of the interviews were analyzed using a hermeneutic phenomenological approach inspired by Ricoeur.

Results

Two main themes were uncovered in the analysis of the transcripts, as follows: (i) the diagnostic journey; and (ii) life with cardiac symptoms and a disability. The women indicated that they had experienced difficulties in utilizing the Canadian healthcare system prior to receiving a cardiac diagnosis, including long waitlists, expensive and unreliable transport, issues with accessibility, and dealing with providers’ attitudinal barriers regarding disability. Receiving a diagnosis was challenging due to poor relationships with healthcare providers; however, having a same-sex provider seemed essential to receiving adequate care. Self-managing a disability and heart disease had significant physical and psychological impact, which was lightened by financial and social supports, modified lifestyle choices, and self-advocacy.

Conclusions

Women with physical disabilities are often forgotten in discussions encompassing equity and inclusion. The participants’ experiences offer insight into what changes are needed within the Canadian healthcare system in order to improve outcomes for these women.

Gender-stratified analyses of symptoms associated with acute coronary syndrome in telephone triage: a cross-sectional study

OBJECTIVES

To identify clinical variables that are associated with the diagnosis acute coronary syndrome (ACS) in women and men with chest discomfort who contact out-of-hours primary care (OHS-PC) by telephone, and to explore whether there are indications whether these variables differ among women and men.

DESIGN

Cross-sectional study in which we compared patient and call characteristics of triage call recordings between women with and without ACS, and men with and without ACS.

SETTING

Nine OHS-PC in the Netherlands.

PARTICIPANTS

993 women and 802 men who called OHS-PC for acute chest discomfort (pain, pressure, tightness or discomfort) between 2014 and 2016.

PRIMARY OUTCOME MEASURE

Diagnosis of ACS retrieved from the patient's medical record in general practice, including hospital specialists' discharge letters.

RESULTS

Among 1795 patients (mean age 58.8 (SD 19.5) years, 55.3% women), 15.0% of men and 8.6% of women had an ACS. In both sexes, retrosternal chest pain was associated with ACS (women with ACS vs without 62.3% vs 40.3%, p=0.002; men with ACS vs without 52.5% vs 39.7%, p=0.032; gender interaction, p=0.323), as was pressing/heavy/tightening pain (women 78.6% vs 61.5%, p=0.011; men 82.1% vs 57.4%, p=<0.001; gender interaction, p=0.368) and radiation to the arm (women 75.6% vs 45.9%, p<0.001; men 56.0% vs 34.8%, p<0.001; gender interaction, p=0.339). Results indicate that only in women were severe pain (65.4% vs 38.1%, p=0.006; gender interaction p=0.007) and radiation to jaw (50.0% vs 22.9%, p=0.007; gender interaction p=0.015) associated with ACS.Ambulances were dispatched equally in women (72.9%) and men with ACS (70.0%).

CONCLUSION

Our results indicate there were more similarities than differences in symptoms associated with the diagnosis ACS for women and men. Important exceptions were pain severity and radiation of pain in women. Whether these differences have an impact on predicting ACS needs to be further investigated with multivariable analyses.

Specific prodromal symptoms in patients with acute coronary syndrome

AIMS

Assessing the prodromal cardiac symptoms in patients with acute coronary syndrome (ACS) and compare them with healthy population.

BACKGROUND

Identifying specific prodromal cardiac symptoms can play an important role in screening people at risk.

DESIGN

A comparative study of prodromal symptoms.

METHODS

In this comparison study, an 80-item checklist of prodromal symptoms was designed and completed by 337 participants in three groups (Patient group I, Patient group II and Healthy group). All participants were studied over a period of six months (from May to October 2017). SPSS-15 software was used to analyse the data.

RESULTS

The symptoms of pain/discomfort in chest, pain/discomfort centred in the superior part of chest, pain/discomfort in the left breast and numbness or burning of both arms were the most important symptoms to predict ACS incidence in the two patient groups (odds ratio > 4 and p ≤ .05).

Typical and Atypical Symptoms of Acute Coronary Syndrome: Time to Retire the Terms?

Studies indicate that symptoms labeled as "atypical" are more common in women evaluated for myocardial infarction (MI) and may contribute to the lower likelihood of a diagnosis and delayed treatment and result in poorer outcomes compared with men with MI. Atypical pain is frequently defined as epigastric or back pain or pain that is described as burning, stabbing, or characteristic of indigestion. Typical symptoms usually include chest, arm, or jaw pain described as dull, heavy, tight, or crushing. In a recent article published in the Journal of the American Heart Association (JAHA), Ferry and colleagues addressed presenting symptoms in men and women diagnosed with MI and reported that typical symptoms in women were more predictive of a diagnosis of MI than for men. A critical question is, are there really typical or atypical symptoms, and if so, who is the reference group? We propose that researchers and clinicians either discontinue using the terms typical and atypical or provide the reference group to which the terms apply (eg, men versus women). We believe it is past time to standardize the symptom assessment for MI so that proper and rapid diagnostic testing can be undertaken; however, we cannot standardize the symptom experience. When we do this, we are at risk of having study results, such as those of Ferry and colleagues, that vary from prior evidence and could lead to what the authors hope to avoid: disadvantaging women in receiving expeditious diagnostic testing and treatment for acute coronary syndrome.

Development and usability testing of HEARTPA♀N: protocol for a mixed methods strategy to develop an integrated smartphone and web-based intervention for women with cardiac pain

INTRODUCTION

More women experience cardiac pain related to coronary artery disease and cardiac procedures compared with men. The overall goal of this programme of research is to develop an integrated smartphone and web-based intervention (HEARTPA♀N) to help women recognise and self-manage cardiac pain.

METHODS AND ANALYSIS

This protocol outlines the mixed methods strategy used for the development of the HEARTPA♀N content/core feature set (phase 2A), usability testing (phase 2B) and evaluation with a pilot randomised controlled trial (RCT) (phase 3). We are using the individual and family self-management theory, mobile device functionality and pervasive information architecture of mHealth interventions, and following a sequential phased approach recommended by the Medical Research Council to develop HEARTPA♀N. The phase 3 pilot RCT will enable us to refine the prototype, inform the methodology and calculate the sample size for a larger multisite RCT (phase 4, future work). Patient partners have been actively involved in setting the HEARTPA♀N research agenda, including defining patient-reported outcome measures for the pilot RCT: pain and health-related quality of life (HRQoL). As such, the guidelines for Inclusion of Patient-Reported Outcomes in Clinical Trial Protocols (SPIRIT-PRO) are used to report the protocol for the pilot RCT (phase 3). Quantitative data (eg, demographic and clinical information) will be summarised using descriptive statistics (phases 2AB and 3) and a content analysis will be used to identify themes (phase 2AB). A process evaluation will be used to assess the feasibility of the implementation of the intervention and a preliminary efficacy evaluation will be undertaken focusing on the outcomes of pain and HRQoL (phase 3).

ETHICS AND DISSEMINATION

Ethics approval was obtained from the University of Toronto (36415; 26 November 2018). We will disseminate knowledge of HEARTPA♀N through publication, conference presentation and national public forums (Café Scientifique), and through fact sheets, tweets and webinars.

TRIAL REGISTRATION NUMBER

NCT03800082.

Presenting Symptoms in Men and Women Diagnosed With Myocardial Infarction Using Sex-Specific Criteria

Background Sex-specific criteria are recommended for the diagnosis of myocardial infarction, but the impact of these on presenting characteristics is unknown. Methods and Results We evaluated patient-reported symptoms in 1941 patients (39% women) with suspected acute coronary syndrome attending the emergency department in a substudy of a prospective trial. Standardized criteria defined typical and atypical presentations based on pain nature, location, radiation, and additional symptoms. Diagnosis of myocardial infarction was adjudicated using a high-sensitivity cardiac troponin I assay with sex-specific thresholds (>16 ng/L women, >34 ng/L men). Patients identified who were missed by the contemporary assay with a uniform threshold (≥50 ng/L) were reclassified by this approach. Type 1 myocardial infarction was diagnosed in 16% (184/1185) of men and 12% (90/756) of women, with 9 (5%) men and 27 (30%) women reclassified using high-sensitivity cardiac troponin I and sex-specific thresholds. Chest pain was the presenting symptom in 91% (1081/1185) of men and 92% (698/756) of women. Typical symptoms were more common in women than in men with myocardial infarction (77% [69/90] versus 59% [109/184]; P=0.007), and differences were similar in those reclassified (74% [20/27] versus 44% [4/9]; P=0.22). The presence of ≥3 typical features was associated with a positive likelihood ratio for the diagnosis of myocardial infarction in women (positive likelihood ratio, 1.18; 95% CI, 1.03-1.31) but not in men (positive likelihood ratio 1.09; 95% CI, 0.96-1.24). Conclusions Typical symptoms are more common and have greater predictive value in women than in men with myocardial infarction whether or not they are diagnosed using sex-specific criteria.

The Association between Risk Factors and Prodromal Myocardial Infarction Symptoms: A Cross-Sectional Study in Iran

Background

Prodromal symptoms in individuals with risk factors remain challenging, even though myocardial infarction has been noted in research. This study determined the association of risk factors with patients' baseline myocardial infarction related prodromal symptoms.

Methods

In a cross-sectional study, 154 Iranian men and women, mean age 59.62 ± 12.74 years were assessed in 2016-2017. The frequency besides severity of 33 prodromal symptoms and risk factors was assessed using McSweeney Prodromal Myocardial Infarction Symptom Survey.

Results

The main cardiac prodromal symptoms experienced by patients were chest pain/discomfort (n = 99, 64.30%), unusual fatigue (n = 78, 50.60%), and sleep disturbance (n = 33, 20.40%). Women experienced more prodromal symptoms than men (33.26 ± 21.88 vs. 25.48 ± 17.75). Among risk factors, only sex was associated with prodromal symptoms score (P < 0.05).

Conclusion

The frequently experienced prodromal symptoms, i.e., before MI were chest pain/discomfort, unusual fatigue, and sleep disturbance. A crucial finding was the significant association between sex and prodromal symptoms. Identifying prodromal symptoms in patients with risk factors can prevent the incidence of myocardial infarction.

"Make the Call, Don't Miss a Beat" Campaign: Effect on Emergency Medical Services Use in Women with Heart Attack Signs

BACKGROUND

Our objective was to evaluate the relationship between the "Make The Call, Don't Miss a Beat" national mass media campaign and emergency medical services (EMS) use among women with possible heart attack symptoms.

METHODS

We linked campaign TV public service advertisement data with national EMS activation data for 2010 to 2014. We identified EMS activations (i.e., responses) for possible heart attack symptoms and for unintentional injuries for both women and men. We estimated the impact of the campaign on the fraction of the 1.7 to 15.9 million activations of women with possible heart attack symptoms compared with 1.9 million female activations for unintentional injuries within each EMS agency and month using quasi-binomial logistic regression controlling for time and state.

RESULTS

Of the 3,175 U S. counties, 90% were exposed to the campaign. However, less than 2% of U.S. counties reached moderate TV exposure (≥300 gross rating points) during the entire campaign period. We did not observe an increase in the fraction of female activations for possible heart attack during periods or in counties with higher campaign exposure.

CONCLUSIONS

This mass media campaign that relied heavily on TV public service advertisements was not associated with increased EMS use by women with possible heart attack symptoms, even among counties that were more highly exposed to the campaign advertisements.

The Quality of Symptoms in Women and Men Presenting to the Emergency Department With Suspected Acute Coronary Syndrome

INTRODUCTION

More than 5.5 million patients present to emergency departments in the United States annually for potential acute coronary syndrome (ACS); however, diagnosing ACS remains a challenge in emergency departments. Our aim was to describe the quality of symptoms (chest discomfort/description of pain, location/radiation, and overall symptom distress) reported by women and men ruled-in and ruled-out for ACS in emergency departments.

METHODS

The sample consisted of 1,064 patients presenting to emergency departments with symptoms that triggered cardiac workups. Trained research staff obtained data using the ACS Patient Information Questionnaire upon patient presentation to emergency departments.

RESULTS

The sample (n = 1,064) included 474 (44.55%) patients ruled-in and 590 (55.45%) patients ruled-out for ACS. Symptom distress was significantly higher in patients ruled-in versus ruled-out for ACS (7.3 ± 2.6 vs. 6.8 ± 2.5; P = 0.002) and was a significant predictor for an ACS diagnosis in men (odds ratio [OR], 1.10; confidence interval [CI], 1.03-1.17; P = 0.003). Women also reported more chest pressure (51.75% vs. 44.65; P = 0.02) compared with men, and chest pressure was a significant predictor for a diagnosis of ACS (OR, 1.61; CI, 1.03-2.53; P = 0.02).

DISCUSSION

Higher levels of symptom distress may help ED personnel in making a decision to evaluate a patient for ACS, and the presence of chest pressure may aid in making a differential diagnosis of ACS.

Gender difference of symptoms of acute coronary syndrome among Chinese patients: a cross-sectional study

BACKGROUND

The incidence of acute coronary syndrome is increasing in China.

OBJECTIVE

To investigate gender differences in Chinese patients' acute coronary syndrome symptoms, attribution of symptoms and reasons for seeking medical service.

METHODS

This was a cross-sectional, multicentre study. Acute coronary syndrome patients were recruited from five university hospitals located in four cities, between June 2013 and February 2014. Data were collected using the McSweeney acute and prodromal myocardial infarction symptom survey.

RESULTS

A total of 806 patients with acute coronary syndrome (323 men, 483 women) participated in the study. Adjusted (diabetes, smoking, age) logistic regression models revealed that women were significantly more likely to have pain or discomfort in the: central high chest; back, between, or under the shoulder blades; neck or throat; or arms relative to men. Women were also more likely to have unusual fatigue, weakness, shortness of breath or difficulty breathing, or dizziness relative to men. Conversely, women were significantly less likely to have generalised chest pain relative to men. Gender difference in the attribution of symptoms was largely driven by women's attribution to having a heart attack more frequently than men. Finally, women were more often told by a friend to seek medical help or they knew their symptoms were different, while men more frequently sought medical help because their symptoms did not go away.

CONCLUSIONS

There were gender differences in pain, discomfort and other symptoms. Both potential patients and healthcare providers need to be more aware of potential gender differences in acute coronary syndrome symptoms and decisions to seek care to ensure quick access.

Gender Disparities in Preoperative Resource Use for Wrist Arthroscopy

BACKGROUND

Although national efforts to minimize gender biases exist, gender differences in surgery persist. This study aims to investigate gender differences in preoperative resource use of patients undergoing wrist arthroscopy for nontraumatic wrist pain.

METHODS

Patients who underwent a wrist arthroscopy for nontraumatic pain from 2009 to 2015 were selected from the Truven MarketScan databases. Demographic and preoperative resource use data were recorded. Multivariable regression models were performed to examine the relationship between gender and preoperative resource use and to investigate the cost of these services.

RESULTS

A total of 8792 patients, 3805 men and 4987 women, met our inclusion criteria. Women were less likely to use imaging modalities preoperatively (OR, 0.08; 95 percent CI, 0.07 to 1.00; p = 0.02). However, women used more occupational therapy (OR, 1.2; 95 percent CI, 1.1 to 1.3; p = 0.002), nonnarcotic analgesia (OR, 1.2; 95 percent CI, 1.1 to 1.3; p = 0.001), and narcotic analgesia (OR, 1.6; 95 percent CI, 1.5 to 1.8; p < 0.001). Preoperative costs during the 12 months before surgery were similar between genders ($1308 versus $1367, respectively; p = 0.07). However, women accrued more costs from occupational therapy ($130 versus $93; p = 0.003), and nonnarcotic ($65 versus $46; p < 0.001) and narcotic medications ($568 versus $197; p < 0.001).

CONCLUSIONS

Significant gender differences exist in the preoperative care for patients undergoing wrist arthroscopy. Men use more imaging, implying more intense preoperative investigation for wrist pain, whereas women use more conservative measures, highlighting possible implicit provider biases in preoperative management and potential gender differences in disease presentation.

Sex Differences in Cardiac Troponin Testing in Patients Presenting to the Emergency Department with Chest Pain

BACKGROUND

Elevated cardiac troponin (cTn), with signs/symptoms of ischemia, is a key element in a diagnosis of myocardial infarction (MI). Underdiagnosis of MI in women has been attributed to atypical symptoms, inconsistent ECG findings, and less diagnostic testing. We sought to determine if there are sex differences in cTn testing following presentation to the emergency department (ED) with a chief complaint of ischemic chest pain (CP) and if presentation affects diagnostic assessment.

METHODS

All adults presenting to six hospital EDs in the Vancouver, Canada with a chief complaint of ischemic CP from 2009 to 2013 were included. The highest cTn level within 24 hours of ED presentation was used. CP was classified into cardiac- or respiratory dominant based on standard Canadian Emergency Department Triage and Acuity Scale coding. Chi-square testing was used to test for sex differences in CP categories and cTn testing within 24 hours. Logistic regression models were used to examine the association between sex, cTn testing, and CP categories.

RESULTS

Of 27,063 patients with ischemic CP, cardiac presentation was more common in men than women, irrespective of age. Among cardiac CP, 24.7% of men were <50 years compared to 18.2% of women; however, more women (19.9%) than men (11.6%) were >80 years. Overall, women were 1.8% less likely to have cTn testing; in patients <50 years, testing was markedly lower in women compared to men [odds ratio, OR (95% confidence intervals, CI) 0.78 (0.70-0.87)]. The odds of cardiac catheterization within 90 days of ED presentation were lower in women [OR, (95% CI) 0.52 (0.44-0.63)]. Even with cardiac CP, 17.7% of women versus 32.7% of men had cardiac catheterization.

CONCLUSIONS

In men and women presenting to the ED with ischemic CP, cTn testing overall is similar except among young women under 50 years old, where it is markedly lower. Women undergo less cardiac catheterization, irrespective of CP type.

Acute myocardial infarction in young women: current perspectives

Acute myocardial infarction (AMI) is the leading cause of death in women worldwide. Every year, in the USA alone, more than 30,000 young women <55 years of age are hospitalized with AMI. In recent decades, the incidence of AMI is increasing in younger women in the context of increasing metabolic syndrome, diabetes mellitus, and non-traditional risk factors such as stress, anxiety, and depression. Although women are classically considered to present with atypical chest pain, several observational data confirm that men and women experience similar rates of chest pain, with some differences in intensity, duration, radiation, and the choice of descriptors. Women also experience more number of symptoms and more prodromal symptoms compared with men. Suboptimal awareness, sociocultural and financial reasons result in pre-hospital delays in women and lower rates of access to care with resulting undertreatment with guideline-directed therapies. Causes of AMI in young women include plaque-related MI, microvascular dysfunction or vasospasm, and spontaneous coronary artery dissection. Compared with men, women have greater in-hospital, early and late mortality, as a result of baseline comorbidities. Post-AMI women have lower referral to cardiac rehabilitation with more dropouts, lower levels of physical activity, and poorer improvements in health status compared with men, with higher inflammatory levels at 1-year from index presentation. Future strategies should focus on primary and secondary prevention, adherence, and post-AMI health-related quality of life. This review discusses the current evidence in the epidemiology, diagnosis, and treatment of AMI in young women.

Symptoms Suggestive of Acute Coronary Syndrome: When Is Sex Important?

BACKGROUND

Studies have identified sex differences in symptoms of acute coronary syndrome (ACS); however, retrospective designs, abstraction of symptoms from medical records, and variations in assessment forms make it difficult to determine the clinical significance of sex differences.

OBJECTIVE

The aim of this study is to determine the influence of sex on the occurrence and distress of 13 symptoms for patients presenting to the emergency department for symptoms suggestive of ACS.

METHODS

A total of 1064 patients admitted to 5 emergency departments with symptoms triggering a cardiac evaluation were enrolled. Demographic and clinical variables, symptoms, comorbid conditions, and functional status were measured.

RESULTS

The sample was predominantly male (n = 664, 62.4%), white (n = 739, 69.5%), and married (n = 497, 46.9%). Women were significantly older than men (61.3 ± 14.6 vs 59.5 ± 13.6 years). Most patients were discharged with a non-ACS diagnosis (n = 590, 55.5%). Women with ACS were less likely to report chest pain as their chief complaint and to report more nausea (odds ratio [OR], 1.56; confidence interval [CI], 1.00-2.42), shoulder pain (OR, 1.76; CI, 1.13-2.73), and upper back pain (OR, 2.92; CI, 1.81-4.70). Women with ACS experienced more symptoms (6.1 vs 5.5; P = .026) compared with men. Men without ACS had less symptom distress compared with women.

CONCLUSIONS

Women and men evaluated for ACS reported similar rates of chest pain but differed on other classic symptoms. These findings suggest that women and men should be counseled that ACS is not always accompanied by chest pain and multiple symptoms may occur simultaneously.

Relations of Sex to Diagnosis and Outcomes in Acute Coronary Syndrome

BACKGROUND

The atypical presentation of women with acute coronary syndrome (ACS) has been related to delayed diagnosis and treatment, which may explain worse outcome compared with men.

METHODS AND RESULTS

We analyzed pooled data of 2520 patients of 2 prospective cohorts in terms of differences in presentation and management of women and men suggestive of ACS. Using logistic regression, we established 2 diagnostic models and tested their diagnostic performance in both sexes separately. Sex-specific differences in management of patients with ACS were ascertained and a 2-year follow-up was performed. Women were older than men (median 67 versus 61 years, P=0.001), had more often dyspnea (22% versus 18%, P=0.024), nausea or vomiting (26% versus 16%, P=0.001) and radiating chest pain (47% versus 40%, P=0.001). Classical risk factors (smoking, diabetes mellitus, dyslipidemia or known coronary artery disease) were less frequent in women. Diagnostic models showed no significant sex-related differences in diagnostic performance in a "first contact" setting (medical history and symptoms) or after "complete triage" (including ECG and biomarkers). Women with ACS underwent coronary angiography (73.8% versus 84.3%, P<0.001) and revascularization (53.8% versus 70.1%, P<0.001) less frequently. Two-year incidence of myocardial infarction and death was similar in both sexes, but revascularization and cardiac rehospitalization were more frequent in men.

CONCLUSIONS

In a large cohort of patients with suspected ACS, sex differences in clinical presentation did not impair diagnostic accuracy. Two-year outcomes were comparable. Our findings suggest a benefit of chest pain units to minimize sex differences in ACS management and prognosis.

Gender differences in the use of cardiovascular interventions in HIV-positive persons; the D:A:D Study

INTRODUCTION

There is paucity of data related to potential gender differences in the use of interventions to prevent and treat cardiovascular disease (CVD) among HIV-positive individuals. We investigated whether such differences exist in the observational D:A:D cohort study.

METHODS

Participants were followed from study enrolment until the earliest of death, six months after last visit or February 1, 2015. Initiation of CVD interventions [lipid-lowering drugs (LLDs), angiotensin-converting enzyme inhibitors (ACEIs), anti-hypertensives, invasive cardiovascular procedures (ICPs) were investigated and Poisson regression models calculated whether rates were lower among women than men, adjusting for potential confounders.

RESULTS

Women (n = 12,955) were generally at lower CVD risk than men (n = 36,094). Overall, initiation rates of CVD interventions were lower in women than men; LLDs: incidence rate 1.28 [1.21, 1.35] vs. 2.40 [2.34, 2.46]; ACEIs: 0.88 [0.82, 0.93] vs. 1.43 [1.39, 1.48]; anti-hypertensives: 1.40 [1.33, 1.47] vs. 1.72 [1.68, 1.77] and ICPs: 0.08 [0.06, 0.10] vs. 0.30 [0.28, 0.32], and this was also true for most CVD interventions when exclusively considering periods of follow-up for which individuals were at high CVD risk. In fully adjusted models, women were less likely to receive CVD interventions than men (LLDs: relative rate 0.83 [0.78, 0.88]; ACEIs: 0.93 [0.86, 1.01]; ICPs: 0.54 [0.43, 0.68]), except for the receipt of anti-hypertensives (1.17 [1.10, 1.25]).

CONCLUSION

The use of most CVD interventions was lower among women than men. Interventions are needed to ensure that all HIV-positive persons, particularly women, are appropriately monitored for CVD and, if required, receive appropriate CVD interventions.

Self-Management Interventions for Women With Cardiac Pain: A Systematic Review and Meta-analysis

BACKGROUND

Cardiac pain is considered the primary indicator of coronary artery disease (CAD). Existing reviews lack appropriate numbers of women or sex-based subgroup analyses, or both; thus, the benefits of self-management (women with cardiac pain actively participating in their own care and treatment) remain uncertain.

METHODS

Using methods described by the Evidence for Policy and Practice Information and Co-ordinating Centre at the Institute of Education, 7 databases were systematically searched to examine and synthesize the evidence on self-management interventions for women with cardiac pain and cardiac pain equivalents, such as fatigue, dyspnea, and exhaustion.

RESULTS

Our search yielded 22,402 article titles and abstracts. Of these, 57 randomized controlled trials were included in a final narrative synthesis, comprising data from 13,047 participants, including 5299 (41%) women. Self-management interventions targeting cardiac pain in women compared with a control population reduced (1) cardiac pain frequency and cardiac pain proportion (obstructive and nonobstructive CAD), (2) fatigue at 12 months, and (3) dyspnea at 2 months. There was no evidence of group differences in postprocedural (percutaneous coronary intervention or cardiac surgery) pain. Results indicated that self-management interventions for cardiac pain were more effective if they included a greater proportion of women (standardized mean difference [SMD], -0.01; standard error, 0.003; P = 0.02), goal setting (SMD, -0.26; 95% confidence interval [CI], -0.49 to -0.03), and collaboration/support from health care providers (SMD, -0.57; 95% CI, -1.00 to -0.14).

CONCLUSIONS

The results of this review suggest that self-management interventions reduce cardiac pain and cardiac pain equivalents.

Self-management of cardiac pain in women: an evidence map

OBJECTIVE

To describe the current evidence related to the self-management of cardiac pain in women using the process and methodology of evidence mapping.

DESIGN AND SETTING

Literature search for studies that describe the self-management of cardiac pain in women greater than 18 years of age, managed in community, primary care or outpatient settings, published in English or a Scandinavian language between 1 January 1990 and 24 June 2016 using AMED, CINAHL, ERIC, EMBASE, MEDLINE, Proquest, PsychInfo, the Cochrane Library, Scopus, Swemed+, Web of Science, the Clinical Trials Registry, International Register of Controlled Trials, MetaRegister of Controlled Trials, theses and dissertations, published conference abstracts and relevant websites using GreyNet International, ISI proceedings, BIOSIS and Conference papers index. Two independent reviewers screened using predefined eligibility criteria. Included articles were classified according to study design, pain category, publication year, sample size, per cent women and mean age.

INTERVENTIONS

Self-management interventions for cardiac pain or non-intervention studies that described views and perspectives of women who self-managed cardiac pain.

PRIMARY AND SECONDARY OUTCOMES MEASURES

Outcomes included those related to knowledge, self-efficacy, function and health-related quality of life.

RESULTS

The literature search identified 5940 unique articles, of which 220 were included in the evidence map. Only 22% (n=49) were intervention studies. Sixty-nine per cent (n=151) of the studies described cardiac pain related to obstructive coronary artery disease (CAD), 2% (n=5) non-obstructive CAD and 15% (n=34) postpercutaneous coronary intervention/cardiac surgery. Most were published after 2000, the median sample size was 90 with 25%-100% women and the mean age was 63 years.

CONCLUSIONS

Our evidence map suggests that while much is known about the differing presentations of obstructive cardiac pain in middle-aged women, little research focused on young and old women, non-obstructive cardiac pain or self-management interventions to assist women to manage cardiac pain.

A Qualitative Study of Symptom Experiences of Women With Acute Coronary Syndrome

BACKGROUND

Most studies show that women with symptoms of acute coronary syndrome (ACS) delay seeking care longer than men do. Contributing factors include women being more likely to experience diverse symptoms, to experience symptoms that do not match preexisting symptom expectations, to interpret symptoms as noncardiac, and to minimize symptoms until they become incapacitating.

OBJECTIVE

The aim of the study is to identify factors influencing women's ability to recognize and accurately interpret symptoms of suspected ACS.

METHODS

This qualitative study used in-depth interviews with 18 women diagnosed with ACS to determine how they recognized, interpreted, and acted on symptoms. An interview guide developed from the author's initial research was used to provide structure for the process.

RESULTS

All of the women went through a process of recognizing and interpreting their symptoms. Eight women had symptoms arise abruptly. Most of these women recognized a change immediately, "knew" to go for treatment, and did so quickly. Three women had vague symptoms that started slowly, converting unexpectedly to intense symptoms prompting them to seek care urgently. The remaining 7 women had evolving symptoms, were more likely to interpret symptoms as unrelated to their heart, and avoided disclosing symptoms to others. Despite recognizing that the situation may be serious, women with evolving symptoms adopted a wait-and-see approach.

CONCLUSION

Women with less severe, intermittent, or evolving symptoms are at increased risk for delayed presentation, diagnosis, and treatment for ACS. These women should be targeted for educational and behavioral interventions.

Congruence of the Medical Record and Subject Interview on Time of Symptom Onset in Patients Diagnosed With Acute Coronary Syndrome

BACKGROUND

Past research has shown discrepancies between the time of symptom onset for patients with acute coronary syndrome (ACS) as documented in the medical record (MR) and patients' recall of the time assessed through subject interviews done later by researchers.

PURPOSE

The aim of this study is to determine if there were differences between the time of symptom onset documented in the MR and subject interview taking into consideration sex, age group, and recall period for patients admitted to the emergency department for symptoms suggestive of ACS.

METHODS

A secondary analysis was conducted on data from the PROMOTION (Patient Response to Myocardial Infarction Following a Teaching Intervention Offered by Nurses) trial, a multicenter randomized clinical trial to reduce patient prehospital delay to treatment in ACS.

RESULTS

Of the 3522 subjects with CAD enrolled into the trial, 3087 subjects completed 2-year follow-up. Of these, 331 subjects sought treatment in the emergency department for ACS symptoms and 276 patients (83%) had complete information on the time of symptom onset from both sources. Of the 276 patients, 25 (9%) had differing times more than 48 hours and were thus excluded. The median difference between the 2 sources was 45.0 minutes. When both times were examined, there were no significant differences in time by sex (P = .720) or by age group (P = .188). The median number of days between the interview and the date of symptom onset was 29.5 days. There was a significant correlation between differences in the time of symptom onset and the length of recall period (rs = 0.148, P = .023). In multivariable modeling, a longer recall period was associated with greater median differences in the symptom onset time (b = 13.2, P = .023).

CONCLUSION

These results suggest that the time of symptom onset obtained at the time of the index event and documented in the MR is not interchangeable with data obtained later by research staff, especially if the interview is not conducted near the time of the index event.

Acute coronary syndromes in women and men

Evidence of sex-related disparities in the care and outcomes of patients with acute coronary syndrome (ACS) emerged >30 years ago, and yet the mechanisms behind these sex-specific differences remain unclear. In this Review, we discuss the current literature on differences between women and men in the clinical presentation, pathophysiology, evaluation, management, and outcomes of ACS. Although the symptoms of ACS and the benefits of therapy generally overlap between women and men, women continue to receive less-aggressive invasive and pharmacological therapy than men. In addition, young women in particular have worse short-term and long-term outcomes than men. To understand better the mechanisms behind these continued disparities, we have identified areas of future research that need to be urgently addressed in fields that range from clinical evaluation and management, to increasing representation of women in research.

Symptom clusters in patients presenting to the emergency department with possible acute coronary syndrome differ by sex, age, and discharge diagnosis

OBJECTIVES

To identify classes of individuals presenting to the ED for suspected ACS who shared similar symptoms and clinical characteristics.

BACKGROUND

Describing symptom clusters in undiagnosed patients with suspected ACS is a novel and clinically relevant approach, reflecting real-world emergency department evaluation procedures.

METHODS

Symptoms were measured using a validated 13-item symptom checklist. Latent class analysis was used to describe symptom clusters.

RESULTS

The sample of 874 was 37% female with a mean age of 59.9 years. Four symptom classes were identified: Heavy Symptom Burden (Class 1), Chest Symptoms and Shortness of Breath (Class 2), Chest Symptoms Only (Class 3), and Weary (Class 4). Patients with ACS were more likely to cluster in Classes 2 and 3. Women and younger patients were more likely to group in Class 1.

CONCLUSIONS

Further research is needed to determine the value of symptom clusters in the ED triage and management of suspected ACS.

Prodromal symptoms associated with acute coronary syndrome acute symptom presentation

OBJECTIVE

Prodromal symptoms (PS), indicative of myocardial ischemia, are frequently unrecognized by individuals prior to an acute coronary syndrome (ACS). ACSs are the leading cause of death worldwide. This study describes (1) the prevalence and association of PS with patients' baseline ACS-related acute symptoms of pain intensity and state anxiety and (2) the relationship of PS to co-morbidity.

METHODS

An exploratory sub-analysis was performed. Cross sectional data identified prodromal predictors of ACS pain intensity (numeric rating scale 0-10 (NRS)) and state anxiety (Speilberger state-trait anxiety personality inventory (STAI)). ACS patients (n=121) admitted to a community rural emergency department completed the prodromal symptom screening scale (PS-SS) and reported baseline cardiac pain intensity, state, and trait anxiety.

RESULTS

Increased ACS pain intensity was associated with PS. Median pain scores were higher by two points for those with prodromal headache, p=0.006, and anxiety, p=0.017, and one point higher for those with sleep disturbances, p=0.012. PS were not associated with state or trait anxiety. Hypertensive individuals were 7.5 times more likely to experience prodromal fatigue prior to their ACS event.

CONCLUSION

Results extend current knowledge of the predictive value that prodromal headache, sleep disturbance and anxiety may have on individuals' acute symptom presentation. A prospective, prognostic study is required in order to determine whether PS are predictive of adverse cardiac events and if PS are a stronger predictor of ACS acute symptom presentation, compared with typical ACS-related co-morbidities.
