Does health status differ between men and women in early recovery after myocardial infarction?

Brief Mindfulness-Based Cognitive Therapy in Women With Myocardial Infarction: Results of a Multicenter Randomized Controlled Trial

Background

Elevated perceived stress is associated with adverse outcomes following myocardial infarction (MI) and may account for poorer recovery among women vs men.

Objectives

This randomized controlled trial tested effects of a mindfulness-based intervention on stress levels among women with MI.

Methods

Women with elevated stress (Perceived Stress Scale [PSS-4]≥6) at least 2 months after MI were enrolled from 12 hospitals in the United States and Canada and via community advertising. Participants were randomized to a remotely delivered mindfulness intervention (MBCT-Brief) or heart disease education, both 8 weeks long. Follow-up was 6 months. Changes in stress (PSS-10; primary outcome) and secondary outcomes (depressive symptoms, anxiety, quality of life, disease-specific health status, actigraphy-assessed sleep) were compared between groups.

Results

The sample included 130 women with MI (mean age 59.8 ± 12.8 years, 34% racial/ethnic minorities). In intention-to-treat analysis, PSS-10 scores declined in the MBCT-Brief arm (-0.52 [95% CI: -0.77 to -0.28]) but not the heart disease education arm (-0.19 [95% CI: -0.45 to 0.06]; group×time interaction P = 0.070). The effect was stronger in per-protocol analysis of participants who completed ≥4 intervention sessions (P = 0.049). There were no significant differences in secondary outcomes in intention-to-treat or per-protocol analyses. Within the MBCT-Brief arm, more frequent mindfulness practice was associated with greater reductions in stress (P = 0.007), depressive symptoms (P = 0.017), and anxiety (P = 0.036).

Conclusions

MBCT-Brief was associated with greater 6-month reductions in stress than an active control among adherent participants. More frequent mindfulness practice was associated with greater improvements in psychological outcomes. Strategies to engage women with MI in mindfulness training and support regular home practice may enhance these effects.

Sex differences in quality of life of patients following percutaneous coronary intervention in Vietnam

PURPOSE

Data regarding the health-related quality of life (HRQoL) in men and women after percutaneous coronary intervention (PCI) in low-and-middle incomes countries remains scarce. To investigate sex difference in the HRQoL at 30 days and 12 months post PCI in Vietnam.

METHODS

We used data from a single percutaneous coronary registry established in the Vietnam National Heart Institute. The HRQoL was measured using the EQ-5D-3L instrument via telephone interviews, and information about demographics, clinical presentation and procedures was obtained through face-to-face interviews and medical records. The HRQoL between men and women were compared using independent samples t tests, the Mann-Whitney U test or univariate/multivariate logistic regression.

RESULTS

There were 866 patients included in this cohort, with the proportion of women being nearly half of men (32.1 vs 67.9%). Women were 3.5 years older, had lower income and educational levels but greater prevalence of cardiovascular risk factors. At 30 days, women significantly had more problems in mobility, personal care and pain/discomfort compared to men. At 12 months, women had more problem than men in usual activity. The geometric means of HRQoL was lower in women at 30 days, but not in 12 months. From 30 days to 12 months after discharge, women showed better recovery in mobility compared to men, but not in other dimensions.

CONCLUSIONS

In this first insight of sex differences in HRQoL following PCI in Vietnam, women appeared to have worse quality of life, especially at 30 days after discharge but they showed better recovery in mobility at 12 months compared to men.

Does sex predict quality of life after acute coronary syndromes: an Australian, state-wide, multicentre prospective cohort study

OBJECTIVE

Women have reported higher mortality and major adverse cardiovascular events (MACE) following acute coronary syndromes (ACSs) compared with men. With this in mind, we aimed to identify predictors of poor quality of life (QoL) post-ACS as our primary outcome. We examined predictors of MACE, major cerebrovascular events and major bleeding as our secondary outcome.

DESIGN

Prospective cohort study.

SETTING

30 metropolitan centres across the Victorian Cardiac Outcomes Registry network.

PARTICIPANTS

16 517 patients treated with percutaneous coronary intervention (PCI) for ACS (22.9% females). Selection/inclusion criteria: consecutive patients with successful or attempted PCI for ACS from 2013 to 2016, alive at 30 days post-PCI.

EXCLUSION CRITERIA

patients not fulfilling ACS criteria. At 30 days, 2497 (64.7% females) completed the QoL EQ-5D-3L instrument.

PRIMARY AND SECONDARY OUTCOME MEASURES

QoL, assessed using the EuroQo-5Dimensions (EQ-5D-3L) instrument by telephone at 30 days. Independent predictors of QoL were identified by univariate and multivariate logistic regression analyses.

RESULTS

Women were significantly older with more diabetes, cerebrovascular disease and renal failure. Regarding the primary outcome, female sex was independently associated with moderate/severe impairment in all EQ-5D-3L domains including mobility (OR 2.38, 95% CI 2.06 to 2.75, p<0.001), personal care (OR 2.14, 95% CI 1.73 to 2.66, p<0.001), activities of daily living (OR 1.84, 95% CI 1.63 to 2.08, p<0.001), pain/discomfort (OR 1.44, 95% CI 1.24 to 1.67, p<0.001) and anxiety/depression (OR 1.49, 95% CI 1.30 to 1.70, p<0.001). Women had significantly lower self-rated Visual Analogue Scale scores (80.0 for both groups, IQR 60-85 vs 70-90, p<0.001). There was no significant difference between the sexes in secondary outcomes.

CONCLUSIONS

Female sex was a predictor of poorer QoL following PCI for ACS including significantly higher pain, anxiety and depression. This was independent of age, comorbidities and ACS presentation. There is a clinical need for a tailored approach in female ACS management, for example, emphasis on management of depressive and anxiety symptoms.

Spontaneous Coronary Artery Dissection in Relation to Physical and Emotional Stress: A Retrospective Study in 4 Arab Gulf Countries

Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome and sudden cardiac death. The triggers for SCAD often do not include traditional atherosclerotic risk factors. The most commonly reported triggers are extreme physical or emotional stress. The current study compared in-hospital and follow-up events in patients with SCAD with and without reported stress. Data from 83 patients with a confirmed diagnosis of SCAD were collected retrospectively from 30 centers in 4 Arab Gulf countries (KSA, UAE, Kuwait, and Bahrain) from January 2011 to December 2017. In-hospital myocardial infarction (MI), percutaneous coronary intervention (PCI), ventricular tachycardia/ventricular fibrillation, cardiogenic shock, death, ICD placement, dissection extension) and follow-up (MI, de novo SCAD, death, spontaneous superior mesenteric artery dissection) events were compared between those with and without reported stress. Emotional and physical stress was defined as new or unusually intense stress, within 1 week of their initial hospitalization. The median age of patients in the study was 44 (37-55) years. Foty-two (51%) were women. Stress (emotional, physical, and combined) was reported in 49 (59%) of all patients. Sixty-two percent of women with SCAD reported stress, and 51 % of men with SCAD reported stress. Men more commonly reported physical and combined stress. Women more commonly reported emotional stress (P < 0.001). The presence or absence of reported stress did not impact on overall adverse cardiovascular events (P = 0.8). In-hospital and follow-up events were comparable in patients with SCAD in the presence or absence of reported stress as a trigger.

Sex differences in health outcomes at one year following acute myocardial infarction: A report from the China Patient-Centered Evaluative Assessment of Cardiac Events prospective acute myocardial infarction study

BACKGROUND

We examined sex differences in long-term health outcomes following acute myocardial infarction in China, including mortality, major adverse cardiac events and health status (symptoms, functioning, quality of life).

METHODS

A total of 3415 acute myocardial infarction patients (23.2% women) aged ⩾18 years were enrolled across 10 geographic regions in China (2012-2014) in the China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE) study. Clinical data was abstracted from medical records. Generic (Euro-Quality of Life Scale) and disease-specific (Seattle Angina Questionnaire) health status was obtained through interviews at baseline and one year.

RESULTS

At one year, women with acute myocardial infarction had a higher risk of death from all causes ( p<0.001), but had similar rates of major adverse cardiac events ( p=0.2). Women had lower mean generic (Euro-Quality of Life Scale utility index score: 0.90±0.13 vs 0.94±0.11) and disease specific health scores indicating poorer functioning (Seattle Angina Questionnaire summary score: 75.3±11.4 vs 78.4±9.7) and higher rates of daily/weekly angina (Seattle Angina Questionnaire angina frequency score ⩽60 vs >60: 9.1% vs 4.7%; all p<0.001). In multivariable analysis, there was a significant association between female sex and mortality (β=0.45, standard error=0.21, p=0.03) but not for major adverse cardiac events (β=-0.02, standard error=0.14, p=0.89). The association between female sex and worse generic health status persisted (β=-0.02, standard error=0.01, p=0.003), but was no longer significant between sexes for disease-specific health status (β=-0.82, standard error=0.58, p=0.154) or daily/weekly angina (odds ratio=1.39; 95% confidence interval 0.88-2.21).

CONCLUSION

Women in China have higher crude rates of all-cause/cardiovascular death versus men, as well as worse generic/disease specific health status at one-year post-acute myocardial infarction. The association between female sex and worse generic health status persisted following adjustment.

Spontaneous Coronary Artery Dissection: Current State of the Science: A Scientific Statement From the American Heart Association

Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome, myocardial infarction, and sudden death, particularly among young women and individuals with few conventional atherosclerotic risk factors. Patient-initiated research has spurred increased awareness of SCAD, and improved diagnostic capabilities and findings from large case series have led to changes in approaches to initial and long-term management and increasing evidence that SCAD not only is more common than previously believed but also must be evaluated and treated differently from atherosclerotic myocardial infarction. High rates of recurrent SCAD; its association with female sex, pregnancy, and physical and emotional stress triggers; and concurrent systemic arteriopathies, particularly fibromuscular dysplasia, highlight the differences in clinical characteristics of SCAD compared with atherosclerotic disease. Recent insights into the causes of, clinical course of, treatment options for, outcomes of, and associated conditions of SCAD and the many persistent knowledge gaps are presented.

Sex Differences in Trajectories of Risk After Rehospitalization for Heart Failure, Acute Myocardial Infarction, or Pneumonia

BACKGROUND

Women have an increased risk of rehospitalization in the immediate postdischarge period; however, few studies have determined how readmission risk dynamically changes on a day-to-day basis over the full year after hospitalization by sex and how these differences compare with the risk for mortality.

METHODS AND RESULTS

We identified >3 000 000 hospitalizations of patients with a principal discharge diagnosis of heart failure, acute myocardial infarction, or pneumonia and estimated sex differences in the daily risk of rehospitalization/death 1 year after discharge from a population of Medicare fee-for-service beneficiaries aged 65 years and older. We calculated the (1) time required for adjusted rehospitalization/mortality risks to decline 50% from maximum values after discharge, (2) time required for the adjusted readmission risk to approach plateau periods of minimal day-to-day change, and (3) extent to which adjusted risks are greater among recently hospitalized patients versus Medicare patients. We identified 1 392 289, 530 771, and 1 125 231 hospitalizations for heart failure, acute myocardial infarction, and pneumonia, respectively. The adjusted daily risk of rehospitalization varied by admitting condition (hazard rate ratio for women versus men, 1.10 for acute myocardial infarction; hazard rate ratio, 1.04 for heart failure; and hazard rate ratio, 0.98 for pneumonia). However, for all conditions, the adjusted daily risk of death was higher among men versus women (hazard rate ratio women versus with men, <1). For both sexes, there was a similar timing of peak daily risk, half daily risk, and reaching plateau.

CONCLUSIONS

Although the association of sex with daily risk of rehospitalization varies across conditions, women are at highest risk after discharge for acute myocardial infarction. Future studies should focus on understanding the determinants of sex differences in rehospitalization risk among conditions.

The Positive Emotions after Acute Coronary Events behavioral health intervention: Design, rationale, and preliminary feasibility of a factorial design study

BACKGROUND

Positive psychological constructs, such as optimism, are associated with greater participation in cardiac health behaviors and improved cardiac outcomes. Positive psychology interventions, which target psychological well-being, may represent a promising approach to improving health behaviors in high-risk cardiac patients. However, no study has assessed whether a positive psychology intervention can promote physical activity following an acute coronary syndrome.

OBJECTIVE

In this article we will describe the methods of a novel factorial design study to aid the development of a positive psychology-based intervention for acute coronary syndrome patients and aim to provide preliminary feasibility data on study implementation.

METHODS

The Positive Emotions after Acute Coronary Events III study is an optimization study (planned N = 128), subsumed within a larger multiphase optimization strategy iterative treatment development project. The goal of Positive Emotions after Acute Coronary Events III is to identify the ideal components of a positive psychology-based intervention to improve post-acute coronary syndrome physical activity. Using a 2 × 2 × 2 factorial design, Positive Emotions after Acute Coronary Events III aims to: (1) evaluate the relative merits of using positive psychology exercises alone or combined with motivational interviewing, (2) assess whether weekly or daily positive psychology exercise completion is optimal, and (3) determine the utility of booster sessions. The study's primary outcome measure is moderate-to-vigorous physical activity at 16 weeks, measured via accelerometer. Secondary outcome measures include psychological, functional, and adherence-related behavioral outcomes, along with metrics of feasibility and acceptability. For the primary study outcome, we will use a mixed-effects model with a random intercept (to account for repeated measures) to assess the main effects of each component (inclusion of motivational interviewing in the exercises, duration of the intervention, and inclusion of booster sessions) from a full factorial model controlling for baseline activity. Similar analyses will be performed on self-report measures and objectively-measured medication adherence over 16 weeks. We hypothesize that the combined positive psychology and motivational interviewing intervention, weekly exercises, and booster sessions will be associated with superior physical activity.

RESULTS

Thus far, 78 participants have enrolled, with 72% of all possible exercises fully completed by participants.

CONCLUSION

The Positive Emotions after Acute Coronary Events III study will help to determine the optimal content, intensity, and duration of a positive psychology intervention in post-acute coronary syndrome patients prior to testing in a randomized trial. This study is novel in its use of a factorial design within the multiphase optimization strategy framework to optimize a behavioral intervention and the use of a positive psychology intervention to promote physical activity in high-risk cardiac patients.

Interventions that improve health-related quality of life in patients with myocardial infarction

PURPOSE

Patients with myocardial infarction (MI) often report lower health-related quality of life (HRQoL) than those without MI. Interventions can affect HRQoL of these patients. The purpose of this review was to identify effective strategies for improving HRQoL among individuals with MI.

METHODS

Three electronic databases were searched and limited to articles peer-reviewed and published in English between 1995 and 2015. We screened titles and abstracts of the retrieved articles for studies that examined effectiveness of interventions to improve HRQoL in patients with MI.

RESULTS

Twenty-three studies were found that examined the effects of behavioural interventions-cardiac rehabilitation programmes (CRP), education and counselling programmes, and other psychological and cognitive interventions-to improve HRQoL in patients with MI. The studies included were mainly randomised controlled trials (14 studies) with a wide age range of participants (18-80 years) and a mean age group of 50-70 years. CRPs, including home- and hospital-based CRPs, regular weekly aerobic training programmes, and group counselling mostly resulted in improvement of HRQoL in patients with MI.

CONCLUSION

Most CRPs and other interventions were beneficial to MI patients. Therefore, patients with MI should be encouraged to participate in programmes that can help promote their HRQoL.

Editor's Choice-Sex differences in young patients with acute myocardial infarction: A VIRGO study analysis

AIMS

Young women with acute myocardial infarction (AMI) have a higher risk of adverse outcomes than men. However, it is unclear how young women with AMI are different from young men across a spectrum of characteristics. We sought to compare young women and men at the time of AMI on six domains of demographic and clinical factors in order to determine whether they have distinct profiles.

METHODS AND RESULTS

Using data from Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO), a prospective cohort study of women and men aged ⩽55 years hospitalized for AMI ( n = 3501) in the United States and Spain, we evaluated sex differences in demographics, healthcare access, cardiovascular risk and psychosocial factors, symptoms and pre-hospital delay, clinical presentation, and hospital management for AMI. The study sample included 2349 (67%) women and 1152 (33%) men with a mean age of 47 years. Young women with AMI had higher rates of cardiovascular risk factors and comorbidities than men, including diabetes, congestive heart failure, chronic obstructive pulmonary disease, renal failure, and morbid obesity. They also exhibited higher levels of depression and stress, poorer physical and mental health status, and lower quality of life at baseline. Women had more delays in presentation and presented with higher clinical risk scores on average than men; however, men presented with higher levels of cardiac biomarkers and more classic electrocardiogram findings. Women were less likely to undergo revascularization procedures during hospitalization, and women with ST segment elevation myocardial infarction were less likely to receive timely primary reperfusion.

CONCLUSIONS

Young women with AMI represent a distinct, higher-risk population that is different from young men.

Sex Differences in the Rate, Timing, and Principal Diagnoses of 30-Day Readmissions in Younger Patients with Acute Myocardial Infarction

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.

Gender differences in the trajectory of recovery in health status among young patients with acute myocardial infarction: results from the variation in recovery: role of gender on outcomes of young AMI patients (VIRGO) study

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.

Gender differences in pre-event health status of young patients with acute myocardial infarction: A VIRGO study analysis

AIMS

We assessed gender differences in pre-event health status (symptoms, functioning, quality of life) in young patients with acute myocardial infarction and whether or not this association persists following sequential adjustment for important covariates. We also evaluated the interaction between gender and prior coronary artery disease, given that aggressive symptom control is a cornerstone of care in those with known coronary disease.

METHODS AND RESULTS

A total of 3501 acute myocardial infarction patients (2349 women) aged 18-55 years were enrolled from 103 US/24 Spanish hospitals (2008-2012). Clinical/health status information was obtained by medical record abstraction and patient interviews. Pre-event health status was measured by generic (Short Form-12, EuroQoL) and disease-specific (Seattle Angina Questionnaire) measures. T-test/chi-square and multivariable linear/logistic regression analysis was utilized, sequentially adjusting for covariates. Women had more co-morbidities and significantly lower generic mean health scores than men (Short Form-12 physical health = 43 ± 12 vs. 46 ± 11 and mental health = 44 ± 13 vs. 48 ± 11); EuroQoL utility index = 0.7 ± 0.2 vs. 0.8 ± 0.2 and visual analog scale = 63 ± 22 vs. 67 ± 20, P < 0.0001 for all. Their disease-specific health status was also worse, with more angina (Seattle Angina Questionnaire angina frequency = 83 ± 22 vs. 87 ± 18), worse physical function (physical limitation = 78 ± 27 vs. 87 ± 21) and poorer quality of life (55 ± 25 vs. 60 ± 22, P<0.0001 for all). In multivariable analysis, the association between female gender and worse generic physical/mental health persisted, as well as worse disease-specific physical limitation and quality of life. The interaction between gender and prior coronary artery disease was not significant in any of the health status outcomes.

CONCLUSION

Young women have worse pre-event health status as compared with men, regardless of their coronary artery disease history. While future studies of gender differences should adjust for baseline health status, an opportunity may exist to better address the pre-event health status of women at risk for acute myocardial infarction.

Sex differences in perceived stress and early recovery in young and middle-aged patients with acute myocardial infarction

BACKGROUND

Younger age and female sex are both associated with greater mental stress in the general population, but limited data exist on the status of perceived stress in young and middle-aged patients presenting with acute myocardial infarction.

METHODS AND RESULTS

We examined sex difference in stress, contributing factors to this difference, and whether this difference helps explain sex-based disparities in 1-month recovery using data from 3572 patients with acute myocardial infarction (2397 women and 1175 men) 18 to 55 years of age. The average score of the 14-item Perceived Stress Scale at baseline was 23.4 for men and 27.0 for women (P<0.001). Higher stress in women was explained largely by sex differences in comorbidities, physical and mental health status, intrafamily conflict, caregiving demands, and financial hardship. After adjustment for demographic and clinical characteristics, women had worse recovery than men at 1 month after acute myocardial infarction, with mean differences in improvement score between women and men ranging from -0.04 for EuroQol utility index to -3.96 for angina-related quality of life (P<0.05 for all). Further adjustment for baseline stress reduced these sex-based differences in recovery to -0.03 to -3.63, which, however, remained statistically significant (P<0.05 for all). High stress at baseline was associated with significantly worse recovery in angina-specific and overall quality of life, as well as mental health status. The effect of baseline stress on recovery did not vary between men and women.

CONCLUSIONS

Among young and middle-aged patients, higher stress at baseline is associated with worse recovery in multiple health outcomes after acute myocardial infarction. Women perceive greater psychological stress than men at baseline, which partially explains women's worse recovery.

Health-related quality of life in European women following myocardial infarction: a cross-sectional study

BACKGROUND

Coronary heart disease is a major contributor to women's health problems.

DESIGN

Self-perceived social support, well-being and health-related quality of life (HRQL) were documented in the cross-sectional HeartQoL survey of European women one and six months after a myocardial infarction.

METHODS

European women were recruited in 18 European countries and grouped into four geographical regions (Southern Europe, Northern Europe, Western Europe and Eastern Europe). Continuous socio-demographic variables and categorical variables were compared by age and region with ANOVA and χ(2), respectively; multiple regression models were used to identify predictors of social support, well-being and HRQL.

RESULTS

Women living in the Eastern European region rated social support, well-being and HRQL significantly lower than women in the other regions. Older women had lower physical HRQL scores than younger women. Eastern European women rated social support, well-being and HRQL significantly lower than women in the other regions. Prediction of the dependent variables (social support, well-being and HRQL) by socio-demographic factors varied by total group, in the older age group, and by region; body mass index and managerial responsibility were the most consistent significant predictors.

Cognitive representations of symptoms of acute coronary syndrome and coping responses to the symptoms as correlates to pre-hospital delay in Omani women and men patients

The major purpose of this study was to describe gender-related cognitive representations of symptoms of acute coronary syndrome and coping responses to the symptoms as correlates to pre-hospital delay. Data were collected from 131 hospitalised Omani patients for acute coronary syndrome (81 men and 50 women) using a structured interview. Statistical analyses indicated that women perceived themselves as less susceptible to acute coronary syndrome than men. They reported the symptoms, shortness of breath and nausea/vomiting, more frequently than did men. Men who reported shorter pre-hospital delay were more likely to be free from diabetes, report neck pain, not experience left arm pain, attribute the symptoms to cardiac origin and not use the coping responses, ‘wait and see’ and ‘attempted to relax’. Whereas, women with shorter pre-hospital delay were more likely to experience sweating, perceive greater overall intensity of the symptoms and not report fear of diagnostic procedures as a barrier to seek healthcare early. The findings of this study suggest that, in women, the emotional aspect of the symptoms dominates the cognitive appraisal process, whereas the pathological aspect of the symptoms dominates the appraisal process in men.

Changes in social support within the early recovery period and outcomes after acute myocardial infarction

OBJECTIVE

To examine changes in social support during early recovery after acute myocardial infarction (AMI) and determine whether these changes influence outcomes within the first year.

METHODS

Among 1951 AMI patients enrolled in a 19-center prospective study, we examined changes in social support between baseline (index hospitalization) and 1 month post-AMI to longitudinally assess their association with health status and depressive symptoms within the first year. We further examined whether 1-month support predicted outcomes independent of baseline support. Hierarchical repeated-measures regression evaluated associations, adjusting for site, baseline outcome level, baseline depressive symptoms, sociodemographic characteristics, and clinical factors.

RESULTS

During the first month of recovery, 5.6% of patients had persistently low support, 6.4% had worsened support, 8.1% had improved support, and 80.0% had persistently high support. In risk-adjusted analyses, patients with worsened support (vs. persistently high) had greater risk of angina (relative risk=1.46), lower disease-specific quality of life (β=7.44), lower general mental functioning (β=4.82), and more depressive symptoms (β=1.94) (all p≤.01). Conversely, patients with improved support (vs. persistently low) had better outcomes, including higher disease-specific quality of life (β=6.78), higher general mental functioning (β=4.09), and fewer depressive symptoms (β=1.48) (all p≤.002). In separate analyses, low support at 1 month was significantly associated with poorer outcomes, independent of baseline support level (all p≤.002).

CONCLUSION

Changes in social support during early AMI recovery were not uncommon and were important for predicting outcomes. Intervening on low support during early recovery may provide a means of improving outcomes.

[Patients' symptoms before a first hospitalization due to Acute Coronary Syndrome]

The objective of this study was to characterize and compare patients regarding their report of experiencing chest pain, dyspnea and limitation of the daily life activities one week before their first hospitalization due to Acute Coronary Syndrome, according to the clinical presentation form, and compare them. This is a cross-sectional, descriptive and correlational study. A clinical evaluation instrument was used to investigate the presence and severity of dyspnea, chest pain and physical restriction due to myocardial ischemia. Regarding the limitation to carry out physical activities, patients diagnosed with unstable angina showed lower capacity the week before hospitalization, and reported experiencing dyspnea and chest pain more frequently than patients who had an infarction in situations ranging from making strong efforts, such as walking uphill or on a flat surface but very quickly, to resting and in situations of little effort.

[Reference values of the Spanish version of the SF-12v2 for the diabetic population]

OBJECTIVE

Perceived health status questionnaires provide important information for health outcomes research. Reference measures are required to interpret the health-related quality of life questionnaires belonging to the short form (SF) health survey family. Previous studies have provided these reference measures for the Spanish general population, but not for specific disease conditions. The aim of the present study was to obtain diabetic population-based norms for the Spanish version of the 12-item short form health survey version II (SF-12v2) in the region of Murcia (Spain).

METHODS

We performed a cross-sectional telephone survey in 1,500 non-institutionalized patients with type 1 or 2 diabetes, aged 18 years or older and representative of the region of Murcia. The central position, dispersion statistics and percentiles were calculated for each of the eight SF-12v2 scales and summary components (physical and mental).

RESULTS

The mental component summary (MCS) (mean: 50.5+/-12.8) was higher than the physical component summary (PCS) (42.5+/-11.8). By sex, men had more favorable MCS (53.6+/-11.6) and PCS (44.9+/-11.2) scores than women (MCS: 47.7+/-13.2; PCS: 40.3+/-11.9). The dimension with the highest score was vitality (men: 57.2+/-11.1; women: 51.9+/-12.1), while that with the lowest score was general health (men: 39.0+/-9.7; women: 35.8+/-10.0). When the groups were stratified by age, scores continued to be higher in men than in women.

CONCLUSIONS

The results of the present study should be taken as the diabetic population-based norms for the Spanish version of the SF-12v2 in the region of Murcia. These results may be useful to establish therapeutics targets, as well as for comparisons with the general, healthy and ill populations.

Recent research in stress, coping and women's health

PURPOSE OF REVIEW

To highlight recent publications in the area of stress and coping, with specific reference to women's physical health status.

RECENT FINDINGS

The transactional model of stress and coping continues to be the mainstay of research in this area. Several longitudinal studies have demonstrated that stress appraisal and resultant coping responses affect health outcome and health-related quality of life in women. In addition to problem-focused coping, women often use distraction methods, seeking social support and faith or religious coping. Psychological interventions in chronic medical conditions need to move beyond education and incorporate more cognitive behavioral components, at the same time addressing women's specific needs.

SUMMARY

Coping behaviors in response to the negative threat appraisal of a chronic or severe medical illness serve to reduce psychological distress. However, it is still not clear how they impact at the physiological level. In addition, coping responses, which enhance positive effects and promote health-related quality of life, merit greater attention from researchers. There is a need for more gender comparative research to improve health outcomes in men and women.
