Systematic review of symptom clusters in cardiovascular disease

Background: Although individual symptoms and symptom trajectories for various cardiovascular conditions have been reported, there is limited research identifying the symptom clusters that may provide a better understanding of patients’ experiences with heart disease. Aims: To summarize the state of the science in symptom cluster research for patients with acute coronary syndrome, myocardial infarction, coronary artery bypass surgery, and heart failure through systematic review and to provide direction for the translation of symptom cluster research into the clinical setting. Methods: Databases were searched for articles from January 2000 through to May 2015 using MESH terms “symptoms, symptom clusters, acute coronary syndrome (ACS), myocardial infarction (MI), coronary heart disease (CHD), ischemic heart disease (IHD), heart failure (HF), coronary artery bypass surgery (CABS), cluster analyses, and latent classes.” The search was limited to human studies, English language articles, and original articles investigating symptom clusters in individuals with heart disease. Fifteen studies meeting the criteria were included. Results: For patients with ACS and MI, younger persons were more likely to experience clusters with the most symptoms. Older adults were more likely to experience clusters with the lowest number of symptoms and more diffuse and milder symptom clusters that are less reflective of classic ACS presentations. For HF patients, symptom clusters frequently included physical and emotional/cognitive components; edema clustered in only three studies. Symptom expression was congruent across geographical regions and cultures. Conclusions: The findings demonstrated similarities in symptom clusters during ACS, MI, and HF, despite multiple methods and analyses. These results may help clinicians to prepare at-risk patients for proper treatment-seeking and symptom self-management behaviors

Symptom Clusters in Acute Myocardial Infarction: A Secondary Data Analysis

Background: Early recognition of acute myocardial infarction (AMI) symptoms and reduced time to treatment may reduce morbidity and mortality. People having AMI experience a constellation of symptoms, but the common constellations or clusters of symptoms have yet to be identified. Objectives: To identify clusters of symptoms that represent AMI. Methods: This was a secondary data analysis of nine descriptive, cross-sectional studies that included data from 1,073 people having AMI in the United States and England. Data were analyzed using latent class cluster analysis, an atheoretical method that uses only information contained in the data. Results: Five distinct clusters of symptoms were identified. Age, race, and sex were statistically significant in predicting cluster membership. None of the symptom clusters described in this analysis included all of the symptoms that are considered typical. In one cluster, subjects had only a moderate to low probability of experiencing any of the symptoms analyzed. Discussion: Symptoms of AMI occur in clusters, and these clusters vary among persons. None of the clusters identified in this study included all of the symptoms that are included typically as symptoms of AMI (chest discomfort, diaphoresis, shortness of breath, nausea, and lightheadedness). These AMI symptom clusters must be communicated clearly to the public in a way that will assist them in assessing their symptoms more efficiently and will guide their treatment-seeking behavior. Symptom clusters for AMI must also be communicated to the professional community in a way that will facilitate assessment and rapid intervention for AMI

Response to symptoms of stroke in the UK: a systematic review

<p>Abstract</p> <p>Background</p> <p>The English National Stroke Strategy suggests that there is a need to improve the response of patients and witnesses to the symptoms of acute stroke to increase rapid access to specialist care. We wished to review the evidence base regarding the knowledge, attitudes and behaviours of stroke patients, witnesses and the public to the symptoms of stroke and the need for an urgent response at the onset of symptoms.</p> <p>Methods</p> <p>We conducted a systematic review of UK articles reporting empirical research on a) awareness of and response to the symptoms of acute stroke or TIA, and b) beliefs and attitudes about diagnosis, early treatment and consequences of acute stroke or TIA. Nine electronic databases were searched using a robust search strategy. Citations and abstracts were screened independently by two reviewers. Data were extracted by two researchers independently using agreed criteria.</p> <p>Results</p> <p>11 studies out of 7144 citations met the inclusion criteria. Methods of data collection included: postal survey (n = 2); interview survey (n = 6); review of hospital documentation (n = 2) and qualitative interviews (n = 1). Limited data reveal a good level of knowledge of the two commonest stroke symptoms (unilateral weakness and speech disturbance), and of the need for an emergency response among the general public and at risk patients. Despite this, less than half of patients recognised they had suffered a stroke. Symptom recognition did not reduce time to presentation. For the majority, the first point of contact for medical assistance was a general practitioner.</p> <p>Conclusions</p> <p>There is an assumption that, in the UK, public knowledge of the symptoms of stroke and of the need for an emergency response is lacking, but there is little published research to support this. Public awareness raising campaigns to improve response to the symptoms of stroke therefore may not produce an increase in desired behaviours. Further research is needed to understand why people who experience or witness stroke symptoms frequently do not call emergency services.</p

Knowledge of modifiable risk factors of heart disease among patients with acute myocardial infarction in Karachi, Pakistan: a cross sectional study

BACKGROUND: Knowledge is an important pre-requisite for implementing both primary as well as secondary preventive strategies for cardiovascular disease (CVD). There are no estimates of the level of knowledge of risk factor of heart disease in patients with CVD. We estimated the level of knowledge of modifiable risk factors and determined the factors associated with good level of knowledge among patients presenting with their first acute myocardial infarction (AMI) in a tertiary care hospital in Karachi, Pakistan. METHODS: A hospital based cross-sectional study was conducted at the National Institute of Cardiovascular Disease, a major tertiary care hospital in Karachi Pakistan. Patients admitted with their first AMI were eligible to participate. Standard questionnaire was used to interview 720 subjects. Knowledge of four modifiable risk factors of heart disease: fatty food consumption, smoking, obesity and exercise were assessed. The participants knowing three out of four risk factors were regarded as having a good level of knowledge. A multiple logistic regression model was constructed to identify the determinants of good level of knowledge. RESULTS: The mean age (SD) was 54 (11.66) years. A mere 42% of our study population had a good level of knowledge. In multiple logistic regression analysis, independent predictors of "good" level of knowledge were (odds ratio [95% confidence interval]) more than ten years of schooling were 2.5 [1.30, 4.80] (verses no schooling at all) and nuclear family system (verses extended family system) 2.54 [1.65, 3.89]. In addition, Sindhi ethnicity OR [3.03], higher level of exercise OR [2.76] and non user of tobacco OR [2.53] were also predictors of good level of knowledge. CONCLUSION: Our findings highlight the lack of good level of knowledge of modifiable risk factors for heart disease among subjects admitted with AMI in Pakistan. There is urgent need for aggressive and targeted educational strategies in the Pakistani population

Concerns and Risk Factor Modification in Women During the Year After Coronary Artery Surgery

Background: Future plans or return to a usual lifestyle has been shown to be of concern to persons recovering from coronary artery surgery. However it is not clear whether early concerns remain stable or evolve over time. Objective: To examine women\u27s concerns about having coronary artery surgery and living with coronary artery disease after surgery over time. Methods: Concerns and risk factor modification strategies were measured in 55 women at 1, 6, and 12 months after coronary artery surgery. The Carr and Powers Stressor Scale and an investigator-developed interview were used. Results: Women\u27s primary concerns shifted over the year from surgical recovery to living with coronary heart disease. At 1 month after surgery, issues related to future plans, such as progress in recovery and resuming lifestyle, were rated as causing the most concern. Concern about diet was the highest rated concern 1 year after surgery. More than half of the women reported exercising more, and approximately three fourths reported eating a better diet 1 year after surgery. Conclusions: The findings demonstrate that women are concerned about diet and exercise, and many women attempt to change their behavior. Capitalizing on women\u27s concerns about living with coronary artery disease may help address risk factors. However, specialized interventions may be needed that focus on women who are not concerned about and/or not engaged in risk reduction behaviors

Optimism, Coping, and Long-Term Recovery from Coronary Artery Surgery in Women

Optimism, coping strategies, and psychological and functional outcomes were measured in 55 women undergoing coronary artery surgery. Data were collected in‐hospital and at 1, 6, and 12 months after surgery. Optimism was related to positive moods and life satisfaction, and inversely related to negative moods. Few relationships were found between optimism and functional ability. Cognitive coping strategies accounted for a mediating effect between optimism and negative mood. Optimists were more likely to accept their situation, and less likely to use escapism. In turn, these coping strategies were inversely related to negative mood and mediated the relationship between optimism and this outcome. Optimism was not related to problem‐focused coping strategies; thus, these coping strategies cannot explain the relationship between optimism and outcomes
