Racial differences in women's prodromal and acute symptoms of myocardial infarction

BACKGROUND

Minority women, especially black and Hispanic women, have higher rates of coronary heart disease and resulting disability and death than do white women. A lack of knowledge of minority women's symptoms of coronary heart disease may contribute to these disparities.

OBJECTIVE

To compare black, Hispanic, and white women's prodromal and acute symptoms of myocardial infarction.

METHODS

In total, 545 black, 539 white, and 186 Hispanic women without cognitive impairment at 15 sites were retrospectively surveyed by telephone after myocardial infarction. With general linear models and controls for cardiovascular risk factors, symptom severity and frequency were compared among racial groups. Logistic regression models were used to examine individual prodromal or acute symptoms by race, with adjustments for cardiovascular risk factors.

RESULTS

Among the women, 96% reported prodromal symptoms. Unusual fatigue (73%) and sleep disturbance (50%) were the most frequent. Eighteen symptoms differed significantly by race (P<.01); blacks reported higher frequencies of 10 symptoms than did Hispanics or whites. Thirty-six percent reported prodromal chest discomfort; Hispanics reported more pain/discomfort symptoms than did black or white women. Minority women reported more acute symptoms (P < .01). The most frequent symptom, regardless of race, was shortness of breath (63%); 22 symptoms differed by race (P <.01). In total, 28% of Hispanic, 38% of black, and 42% of white women reported no chest pain/discomfort.

CONCLUSIONS

Prodromal and acute symptoms of myocardial infarction differed significantly according to race. Racial descriptions of women's prodromal and acute symptoms should assist providers in interpreting women's symptoms.

Factors affecting quality of life in persons on hemodialysis

The purpose of this cross-sectional, correlational study was to describe the quality of life (QOL) in persons with end stage renal disease and explore factors that may affect QOL. Biologicalfunction, symptoms,function, general health perception, and characteristics of the individual and environment explained 61% of the variability in overall QOL. Only anxiety, depression, and general health perception significantly contributed to QOL QOL may be better predicted from psychological factors than physiological factors.

Fatigue in African American women on hemodialysis

The purpose of this study was to examine factors associated with fatigue in African American women with end stage renal disease. Twenty-seven of 36 women in the sample were fatigued. Correlations were found with mood disorder and fatigue (p < .001), social support and uremic malnutrition (p = .003), and anemia and fatigue (p = .012) and mood disorder (p = .039). Anemia, uremic malnutrition, mood disorder, and social support explained 38% of variance in fatigue scores (F = 4.768 [4, 31]; p = .004). Future studies testing interventions that mitigate fatigue are warranted.

Cardiovascular Risks and Physical Activity in Middle-Aged and Elderly African American Women

Cardiovascular disease rates are higher in African American women and they have more cardiovascular risk factors than other groups. Although one of the most important cardiovascular risk reduction behaviors is physical activity, few studies have focused on African American women's cardiovascular risk and physical activity. Therefore, the aims of this descriptive pilot study were to describe modifiable cardiovascular risks and to explore physical activity, as measured by pedometer steps, in younger (n = 22; aged 21-45 years) and older (n = 22; aged 46-75 years) community-dwelling African American women. The total number of pedometer steps recorded in 3 days ranged from 1,153 to 52,742. Day 1 steps were significantly different than day 2 and day 3 steps across the sample (F = 5.30, df = 1, P < .05). Risk factors were similar across the age groups. There was no relationship between the 3-day total or average number of daily steps and cardiovascular risks. Thus, interventions may be used in both age groups, with modifications for cohort effects of approach and health status. Given the disparities in cardiovascular disease and the Healthy People 2010 national health objectives, it is important to continue a variety of efforts to assist adult women of all ages to increase their physical activity and to decrease other CVD risks.

Beta-blocker medication usage in older women after myocardial infarction

PURPOSE

The purpose of this study was to assess demographic characteristics of women prescribed beta-blocker (beta-blocker) medication and compare to those not using beta-blocker medication, and to determine if there are differences in depression and fatigue among women who used beta-blockers compared to nonusers 6-12 months after myocardial infarction (MI).

DATA SOURCES

This was a descriptive cross-sectional study of 84 women (61 using beta-blockers and 23 not using beta-blockers) aged 65 and older who were 6-12 months post-MI. Women had their height and weight measured and completed a Demographic Health Form, the Geriatric Depression Scale, and the Revised Piper Fatigue Scale (RPFS).

CONCLUSIONS

While most of the women were taking beta-blockers after MI (74%), significantly fewer Black women were taking beta-blockers (chi(2) = 5.086, p = 0.032). Most of the beta-blocker users were overweight or obese. There were no significant differences in age, t(82) = 0.7, p = 0.486; body mass index, t(82) = 0.76, p = 0.445; income, chi(2)(df = 2) = 3.219, p = 0.075; mean depression, t(82) = 1.648, p = 0.103; or fatigue scores, t(82) = 0.993, p = 0.324, between beta-blocker users and nonusers. More of those not taking beta-blockers reported fatigue with significantly higher fatigue in the affective meaning dimension of the RPFS, t(82) = 2.272, p = 0.03.

IMPLICATIONS FOR PRACTICE

beta-Blocker medication continues to be underutilized in older women. Because no difference was noted in fatigue and depression in the two groups, these may mean that these side effects are not barriers in prescribing this medication post-MI. Nurse practitioners are in pivotal positions to monitor the ongoing physiological and psychological sequelae post-MI and implement interventions to improve their outcomes.

Integrating gerontology competencies into graduate nursing programs

Current demographic and health care utilization trends strongly indicate a rapidly increasing demand for nurses who are well qualified to care for older adults. Advanced practice nurses are positioned to assume leadership roles in geriatric nursing care; however, they must first acquire adequate preparatory education. This article describes two graduate nursing schools' curricular innovations that were funded by The John A. Hartford Foundation, in collaboration with the American Association of Colleges of Nursing (AACN), through the Geriatric Nursing Education Project: Enhancing Gerontological/Geriatric Nursing for Advanced Practice Nursing. These programs at University of North Carolina at Greensboro and Pennsylvania State University incorporated techniques to translate the Nurse Practitioner and Clinical Nurse Specialist Competencies for Older Adult Care [American Association of Colleges of Nursing. (2004). Nurse practitioner and clinical nurse specialist competencies for older adult care. Washington, DC: AACN] into an advanced practice curriculum and developed strategies to sustain curricular innovations. Finally, lessons learned from these two projects are discussed and recommendations are made for integrating geriatric nursing competencies into graduate programs.

Fatigue and physical activity in older women after myocardial infarction

BACKGROUND

Within 6 years of a myocardial infarction (MI) more women (35%) than men (18%) will have another MI. Participation in physical activity is one of the most effective methods to reduce cardiac risks; however, few older women participate. One of the most frequently reported barriers to physical activity is fatigue.

OBJECTIVES

The specific aims of this study were to (1) describe factors related to fatigue in older women after MI and (2) examine the relationship of fatigue to physical activity in older women after MI.

METHODS

This descriptive correlational study examined the effects of age, body mass index, comorbidities, sleep, beta-blocker medication, depression, and social support on fatigue and physical activity in women (N = 84), ages 65 to 88 years old, 6 to 12 months post-MI. All women had their height and weight measured and completed (1) a health form on comorbidities, physical activity, and medication history; (2) the Geriatric Depression Scale; (3) the Epworth Sleepiness Scale; (4) the Revised Piper Fatigue Scale; and (5) the Social Provisions Scale.

RESULTS

The majority (67%) of the women reported fatigue that they perceived as different from fatigue before their MI. Moderately strong correlations were noted among depression, sleep, and fatigue, and multivariate analysis indicated that depression and sleep significantly accounted for 32.7% of the variance in fatigue. Although only 61% of the women reported participating in physical activity for exercise, most were meeting minimal kilocalories per week for secondary prevention. Fatigue was not significantly associated with participation in physical activity.

CONCLUSION

Describing correlates to fatigue and older women's participation in physical activity after MI are important to develop interventions targeted at increasing women's participation in physical activity, thus decreasing their risk for recurrent MIs.

Inclusion of Women in Nursing Research

BACKGROUND

Although the inclusion of women in research has been examined in medical publications, little is known about how federal mandates have influenced the inclusion of women in research published in nursing journals.

OBJECTIVE

This study aimed to examine the inclusion of women in published nursing research from 1995 to 2001, with a focus on the leading causes of mortality.

METHOD

All the articles in each journal were reviewed, and all the research articles that focused on the top 10 causes of death were sampled to measure the inclusion of women, the characteristics of the women included, the funding source, and the topic.

RESULTS

Of the 1,149 studies reviewed, 139 met the inclusion criteria, and 117 of these studies included women. Only 15 of the studies reported the age of the women in their samples, and 10 of these included women between the ages of 35 and 64 years. The most frequently reported race was White (n = 21), followed by African American (n = 17), Hispanic (n = 6), and Asian (n = 2). There were no associations among year of publication (p =.62), federal funding (p =.30), and inclusion of women. Among the studies including women, heart disease was the most frequent topic (n = 52), followed by Alzheimer's disease (n = 21), cancer (n = 14), respiratory illness (n = 14), and diabetes (n = 8).

DISCUSSION

Although the majority of the research included women, continuing efforts must be made to include sufficient numbers of women.

Informed Consent: A Process to Facilitate Older Adults' Participation in Research

Trust is the foundation of the informed consent process. According to Kass et al., Yet only through vigilance and humility will we, as investigators, be able to live up to the trust that is placed in us; and only if that trust is deserved can the research enterprise survive (1996, p. 28). Therefore, further research should examine the effect of the informed consent process in limiting older adults' participation. Only by re-evaluating the first point of contact, implementing creative strategies to overcome barriers to the informed consent process, and validating these strategies through research will nurses facilitate the inclusion of older adults in research.

Development of the McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey

BACKGROUND/OBJECTIVES

Coronary heart disease (CHD) is the number one cause of death in women, yet, little is known about women's symptoms. Early symptom recognition of CHD in women is essential but most instruments do not assess both prodromal and acute CHD symptoms. Our aims were to develop an instrument validly describing women's prodromal and acute symptoms of myocardial infarction and to establish reliability of the instrument, the McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey (MAPMISS).

METHODS

Four studies contributed to the content validity and reliability of this instrument. Two qualitative studies provided the list of symptoms that were confirmed in study 3. The resulting instrument assesses 37 acute and 33 prodromal symptoms. In study 4, 90 women were retested 7 to 14 days after their initial survey. We used the kappa statistic to assess agreement across administrations.

RESULTS

The women added no new symptoms to the MAPMISS. The average kappa of acute symptoms was 0.52 and 0.49 for prodromal. Next we calculated a weighted score. The mean acute score for time 1 was 19.4 (SD = 14.43); time 2 was 12.4 (SD= 8.79) with Pearson correlation indicating stability (r = .84; P < .01). The mean prodromal score at time 1 was 23.80 (SD= 24.24); time 2 was 26.79 (SD = 30.52) with a Pearson correlation of r = .72; P < .01.

CONCLUSIONS

The tool is comprehensive, has high content validity, and acceptable test-retest reliability. Low kappas were related to few women having those symptoms. The symptom scores remained stable across administrations.

An innovative strategy to enhance new faculty success

Faculty stress is a factor in the current shortage of nursing faculty. New faculty members in schools of nursing are subject to stress from many sources. This article reports on an innovative strategy that decreases stress for new faculty while facilitating faculty tenure success.

Exploring older women's lifestyle changes after myocardial infarction

The researchers explored the failure of older women to attend cardiac rehabilitation after myocardial infarction, and examined facilitating and inhibiting factors in making lifestyle changes. Three global categories emerged: physiological changes, health decisions and actions, and life outcomes of the change process.

I want to know: exploring how older women acquire health knowledge after a myocardial infarction

The purpose of this descriptive naturalistic study was to: (a) explore how older women not participating in outpatient cardiac rehabilitation (CR) acquire health knowledge regarding secondary prevention measures after a myocardial infarction (MI), and (b) describe women's perceived barriers to acquiring this knowledge. Women (N = 15), ages 66-88, participated in semi-structured in-depth interviews. Data analysis resulted in four global categories: (a) previous learning, (b) self knowledge, (c) actively seeking knowledge from others, and (d) information provided by others. Barriers to acquiring health knowledge after MI without the support of outpatient CR were also identified.

An act of courage: women's decision-making processes regarding outpatient cardiac rehabilitation attendance

The purpose of this qualitative study was to describe the factors that affect women's attendance and adherence to a cardiac rehabilitation (CR) program after a myocardial infarction (MI). We used in-depth interviews and a health survey form to collect data. The purposive sample consisted of 40 women who had experienced a first MI within the previous 6 weeks to 12 months. Of those 40, 18 women were not offered the program, 8 declined it, and 14 attended. Using content analysis and constant comparison, we identified three distinct phases: "initial decision," "CR attendance," and "reevaluation." Four data clusters positively influenced the continuation of CR attendance: "Psychological Appraisal," "Program Components," "Staff Behaviors," and "Outcomes." When women encountered a fifth cluster--"Barriers"--they entered the reevaluation phase. Results of this study support specific interventions for each phase.

Do you know them when you see them? Women's prodromal and acute symptoms of myocardial infarction

This study described women's prodromal and acute symptoms associated with myocardial infarction (MI) based on interviews with 76 women who had experienced an MI in the previous year. Sixty-eight women experienced prodromal symptoms including unusual fatigue (70%), shortness of breath (53%), and pain in the shoulder blade/upper back (47%). All women experienced acute symptoms including chest pain/discomfort (90%), unusual fatigue (59%), shortness of breath (59%), and shoulder blade/upper back discomfort (42%). Although women in this study reported numerous prodromal symptoms, none had received a new diagnosis of coronary heart disease (CHD) prior to MI. Practitioners must develop an awareness of and a more comprehensive approach to treating women at risk for CHD. Further research to elucidate prodromal and acute symptom clusters is needed to assist practitioners in early diagnosis of CHD in women.

Challenging the rules: women's prodromal and acute symptoms of myocardial infarction

In this qualitative study the researcher identified symptoms women experienced prior to and during an acute myocardial infarction (AMI). The purposive nonprobability sample for this descriptive naturalistic study consisted of 40 women. Using content analysis and constant comparison, the researcher identified specific symptoms and grouped them according to time of occurrence, prodromal and acute. Thirty-seven women experienced prodromal symptoms, beginning from a few weeks to 2 years prior to their AMI and ranging from 0 to 11 symptoms per woman. The most frequent prodromal symptoms were unusual fatigue (n = 27), discomfort in the shoulder blade area (n = 21), and chest sensations (n = 20), whereas the most frequent acute symptoms were chest sensations (n = 26), shortness of breath (n = 22), feeling hot and flushed (n = 21), and unusual fatigue (n = 18). Only 11 women experienced severe pain during their AMI. Conclusions of this study are threefold: (a) women identified classic and unique symptoms of AMI, which challenge the content of current educational literature; (b) women experienced a gradual progression of number and severity of AMI symptoms; and (c) women need sufficient time to recognize their prodromal symptoms of their AMI.
