Calidad de vida relacionada con la salud dos años después de cirugía de revascularización miocárdica / Health-related quality of life two years after myocardial revascularization surgery

FUNDAMENTO: Describir los niveles de calidad de vida relacionada con la salud (CVRS) alcanzados y la magnitud del efecto de la cirugía de revascularización miocárdica. MÉTODO: Estudio descriptivo prospectivo que, a través del cuestionario de salud SF-12v2 y diferentes variables sociodemográficas y clínicas, evaluó durante dos años de seguimiento la CVRS de pacientes sometidos a cirugía de revascularización miocárdica en el servicio de Cirugía Cardiaca. RESULTADOS: Se incluyeron 175 pacientes con edad media 67 años (rango 45-84), 85,1% hombres. El 72,5% fue sometido a cirugía de revascularización pura y al 80,8% se les practicó un bypass múltiple; el EuroSCORE medio fue 5,3%. Las puntuaciones preoperatorias de los componentes sumario del SF-12v2 reflejaban menor CVRS física (CSF 49,4; DE: 23,4) que mental (CSM 74,8; DE: 20,2), y todas las dimensiones incrementaron al año de la cirugía, especialmente las de salud física (CSF aumentó un 36,8%, p < 0,001). A los dos años todas las dimensiones disminuyeron respecto a las del primer año (excepto Dolor corporal) Se mantuvieron significativamente por encima de las preoperatorias en las dimensiones de salud física (CSF aumentó un 23,9%, p < 0,001) y disminuyeron significativamente las dimensiones Vitalidad y Rol emocional. Las mujeres refirieron niveles de CVRS significativamente peores que los hombres, no encontrando otros factores determinantes de CVRS postoperatoria. CONCLUSIONES: La CVRS durante los dos años de seguimiento tras la revascularización miocárdica mejoró significativamente pero sin llegar a alcanzar los niveles de la población general española. El sexo femenino presentó niveles de salud postoperatoria significativamente inferiores

BACKGROUND: To describe the levels of health-related quality of life (HRQoL) attained and the magnitude of the effect of myocardial revascularization surgery. METHOD: Prospective descriptive study that, using the SF-12v2 health questionnaire and different socio-demographic and clinical variables, evaluated during a two-year follow-up the HRQoL of patients who had received myocardial revascularization surgery in the Cardiac Surgery service. RESULTS: One hundred and seventy-five patients were included with an average age of 67 years (range 45-84), 85.1% men. Seventy-two point five percent received complete revascularization surgery and 80.8% received a multiple bypass; the average EuroSCORE was 5.3%. The preoperative scores of the summary components of the SF-12v2 reflected a lower physical HRQoL (MHQ 49.4; SD: 23.4) than mental HRQoL (PHQ 74.8; SD: 20.2), and all the dimensions increased one year after surgery, especially those for physical health (PHQ increased 36.8%, p < 0.001). Two years later all the dimensions decreased with respect to those of the first year (except Bodily Pain). Scores remained significantly above preoperative ones in the physical health dimensions (PHQ increased 23.9%, p < 0.001) and the dimensions of Vitality and Emotional Role decreased significantly. Women showed significantly worse levels of HRQoL than men; no other determinant factors of postoperative HRQoL were found. CONCLUSIONS: HRQoL during the two-year follow-up after myocardial revascularization improved significantly but without reaching the levels of the general Spanish population. The female sex showed significantly lower levels of postoperative health

Age, knowledge, preferences, and risk tolerance for invasive cardiac care.

BACKGROUND/OBJECTIVES: The extent to which individual knowledge, preferences, and priorities explain lower use of invasive cardiac care among older vs. younger adults presenting with acute coronary syndrome (ACS) is unknown. We directly surveyed a group of patients to ascertain their preferences and priorities for invasive cardiovascular care. DESIGN: We performed a prospective cohort study of adults hospitalized with ACS. We surveyed participants regarding their knowledge, preferences, goals, and concerns for cardiac care, as well as their risk tolerance for coronary artery bypass grafting (CABG). SETTING: Single academic medical center. PARTICIPANTS: Six hundred twenty-eight participants (373 <75 years old; 255 ≥75 years old). MEASUREMENTS: We compared baseline characteristics, knowledge, priorities, and risk tolerance for care across age strata. We also assessed pairwise differences with 95% confidence intervals (CI) between age groups for key variables of interest. RESULTS: Compared with younger patients, older participants had less knowledge of invasive care; were less willing to consider cardiac catheterization (difference between 75-84 and< 65 years old: -7.8%, 95% CI: -14.4%,-1.3%; for ≥85 vs. <65: -15.7%, 95% CI: -29.8%,-1.6%), percutaneous coronary intervention (difference between 75-84 and< 65 years old: -12.8%, 95% CI: -20.8%,-4.8%; for ≥85 vs. <65: -24.8%, 95% CI: -41.2%,-8.5%), and CABG (difference between 75-84 and< 65 years old: -19.0%, 95% CI: -28.2%,-9.9%; for ≥85 vs. <65: -39.1%, 95% CI: -56.0%,-22.2%); and were more risk averse for CABG surgery (p < .001), albeit with substantial inter-individual variability and individual outliers. Many patients who stated they were not initially willing to undergo an invasive cardiovascular procedure actually ended up undergoing the procedure (49% for cardiac catheterization and 22% for PCI or CABG). CONCLUSION: Age influences treatment goals and willingness to consider invasive cardiac care, as well as risk tolerance for CABG. Individuals' willingness to undergo invasive cardiovascular procedures loosely corresponds with whether that procedure is performed after discussion with the care team.

A comparison of angina symptoms reported by clinicians and patients, pre and post revascularisation: Insights from the Stent or Surgery Trial.

BACKGROUND: There are limited data comparing the consistency of angina reporting by patients and clinicians. METHODS: We performed a retrospective analysis of data from the randomised Stent or Surgery (SoS) trial. The trial required reporting of angina using the Canadian Cardiovascular Society (CCS) classification by both patients and clinicians at baseline and twelve months. We compared paired observations to describe the magnitude and direction of differences in clinician and patient reporting. The difference in CCS grade was expressed as the clinician minus patient value. We also examined the proportion of trial subjects reported as being free from angina (CCS = 0) in clinician and patient reporting. RESULTS: Paired CCS data was available for 912 and 887 cases at baseline and 12 months respectively. At baseline, clinicians reported freedom from angina in a single case (1/912 = 0.1%) compared to 70/912 (7.7%) patients (Delta 7.6% 95% CI 5.8 to 9.3, P ≤0.001). At 12 months, the position was reversed, with clinicians reporting 639/887 (72%) angina free compared to 449/887 (50.6%) for patients (Delta -21.4 95% CI -17.1 to -25.8 P ≤ 0.001). For the reported CCS grade at follow-up, the weighted linear kappa for overall agreement was 0.312. Discordant reporting involved the clinician suggesting less angina rather than more (36% v 8% of cases). CONCLUSIONS: These findings have implications for our perception of previous research which has, in the main, focussed on clinician reporting. This emphasises the importance of patient reporting and a need to better understand reasons for discordance.

Association of Mental Health Conditions With Participation in Cardiac Rehabilitation.

Background Mental health conditions are associated with adverse cardiovascular outcomes in patients with ischemic heart disease, and much of this risk can be attributed to poor health behaviors. Although all patients with ischemic heart disease should be referred for cardiac rehabilitation (CR), whether patients with mental health conditions are willing to participate in CR programs is unknown. We sought to compare CR participation rates among patients with ischemic heart disease with versus without comorbid depression and/or posttraumatic stress disorder (PTSD). Methods and Results We used national electronic health records to identify all patients hospitalized for acute myocardial infarction or coronary revascularization at Veterans Health Administration hospitals between 2010 and 2014. Multivariable logistic regression models were used to determine whether comorbid depression/PTSD was associated with CR participation during the 12 months after hospital discharge. Of the 86 537 patients hospitalized for ischemic heart disease between 2010 and 2014, 24% experienced PTSD and/or depression. Patients with PTSD and/or depression had higher CR participation rates than those without PTSD or depression (11% versus 8%; P<0.001). In comparison to patients without PTSD or depression, the odds of participation was 24% greater in patients with depression alone (odds ratio, 1.24; 95% CI, 1.15-1.34), 38% greater in patients with PTSD alone (odds ratio, 1.38; 95% CI, 1.24-1.54), and 57% greater in patients with both PTSD and depression (odds ratio, 1.57; 95% CI, 1.43-1.74). Conclusions Among patients with ischemic heart disease, the presence of comorbid depression and/or PTSD is associated with greater participation in CR, providing an important opportunity to promote healthy lifestyle behaviors and reduce adverse cardiovascular outcomes among these patients.

The association of depression following percutanous coronary intervention with adverse cardiovascular events: Protocol for a systematic review and meta-analysis.

INTRODUCTION: Percutanous coronary intervention (PCI) has been increasingly used for patients suffered from severe coronary artery disease. However, physical trauma and potential adverse events related to the procedure often result in detrimental psychological stress. Accumulating evidences have shown that depression is closely related to coronary artery disease. However, the association of depression following percutanous coronary intervention with adverse cardiovascular events is still unknown. OBJECTIVE: This review is designed to assess the prognostic association of depression following PCI with adverse cardiac events. METHODS AND ANALYSIS: The following databases will be searched, PubMed, the EMBASE, CINAHL and Web of Science of English-language publications from inception to 30 October 2018. Cross-referencing from retrieved studies will be conducted additionally, and observational studies were included. Two independent review authors will do the study selection on the basis of the study eligibility criteria. Extracted data will be used for quantitative and qualitative evidence synthesis as well as to assess methodological quality of studies using the Newcastle-Ottawa checklist. The primary objective of this review is adverse cardiac events, presented as a composition of myocardial infarction, repeat coronary revascularization, cardiac readmission, and cardiac death. The accumulated evidence is evaluated and graded according to Grading of Recommendations, Assessment, Development and Evaluation (GRADE). RESULTS AND CONCLUSIONS: This review will explain the association of depression following percutanous coronary intervention with adverse cardiovascular events, and provide physicians with scientific evidence for psychological intervention in patients after PCI.

A challenge for psychocardiology: Addressing the causes and consequences of patients' perceptions of enduring somatic threat.

The enduring somatic threat (EST) model of posttraumatic stress disorder (PTSD) due to life-threatening medical events suggests that PTSD-like symptoms represent patients' sensitization to cues of ongoing threat in the body. In this article, we review research on the prevalence and consequences of such reactions in cardiovascular disease patients, discuss early tests of the EST model, and then report a new test of the EST model in 143 patients enrolled during their first acute coronary syndrome (ACS; i.e., non-ST elevation myocardial infarction or unstable angina-colloquially, "heart attack"). Invasive coronary revascularization procedures are commonly used to reduce secondary ACS risk and may reduce patients' EST, as revascularized patients often report being "cured." We assessed ACS patients' initial threat perceptions during emergency department (ED) evaluation and followed them for 1 month for PTSD symptoms (specific for ACS, by telephone). We compared PTSD symptoms in participants who were revascularized (n = 65), catheterized but not revascularized (n = 35), and medically managed (n = 43). PTSD symptoms were lower for revascularized versus medically managed participants (B = -5.32, 95% confidence interval [-9.77, -0.87]), t(98.19) = -2.37, p = .020. In a multiple regression model adjusted for clinical and psychosocial covariates, the interaction of threat perception in the ED and ACS management group was significant (greater ED threat predicted greater 1-month PTSD symptoms only in medically managed participants). These findings offer further support for the EST model and suggest that psychological interventions to preempt patients' development of EST should be considered in the hospital.

Myocardial revascularization: factors intervening in the reference and counter-reference in the hospital setting.

OBJECTIVE: To understand the intervening factors in the process of reference and counter-reference of the individual with heart disease in the scenario of high complexity in the health care network. METHOD: Research anchored in the Grounded Theory (Teoria Fundamentada nos Dados). It totaled 21 participants. The data collection scenario was a cardiovascular reference hospital in the south of Brazil and occurred between March and June 2014. RESULTS: The intervening factors in the reference process were the difficulty to access the points of the network and telemedicine and the central to manage the flow of patients in the network. In the counter-reference, there was a link with the hospital and the lack of communication among network professionals. CONCLUSION: It reveals the need to reorganize the service flow in HCN, enhancing PHC, expanding the performance of medium complexity and increasing the capacity of high complexity in order to carry out the process of reference and counter-reference.

Psychological interventions for coronary heart disease.

BACKGROUND: Coronary heart disease (CHD) is the most common cause of death globally, although mortality rates are falling. Psychological symptoms are prevalent for people with CHD, and many psychological treatments are offered following cardiac events or procedures with the aim of improving health and outcomes. This is an update of a Cochrane systematic review previously published in 2011. OBJECTIVES: To assess the effectiveness of psychological interventions (alone or with cardiac rehabilitation) compared with usual care (including cardiac rehabilitation where available) for people with CHD on total mortality and cardiac mortality; cardiac morbidity; and participant-reported psychological outcomes of levels of depression, anxiety, and stress; and to explore potential study-level predictors of the effectiveness of psychological interventions in this population. SEARCH METHODS: We updated the previous Cochrane Review searches by searching the following databases on 27 April 2016: CENTRAL in the Cochrane Library, MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid), and CINAHL (EBSCO). SELECTION CRITERIA: We included randomised controlled trials (RCTs) of psychological interventions compared to usual care, administered by trained staff, and delivered to adults with a specific diagnosis of CHD. We selected only studies estimating the independent effect of the psychological component, and with a minimum follow-up of six months. The study population comprised of adults after: a myocardial infarction (MI), a revascularisation procedure (coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI)), and adults with angina or angiographically defined coronary artery disease (CAD). RCTs had to report at least one of the following outcomes: mortality (total- or cardiac-related); cardiac morbidity (MI, revascularisation procedures); or participant-reported levels of depression, anxiety, or stress. DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles and abstracts of all references for eligibility. A lead review author extracted study data, which a second review author checked. We contacted study authors to obtain missing information. MAIN RESULTS: This review included 35 studies which randomised 10,703 people with CHD (14 trials and 2577 participants added to this update). The population included mainly men (median 77.0%) and people post-MI (mean 65.7%) or after undergoing a revascularisation procedure (mean 27.4%). The mean age of participants within trials ranged from 53 to 67 years. Overall trial reporting was poor, with around a half omitting descriptions of randomisation sequence generation, allocation concealment procedures, or the blinding of outcome assessments. The length of follow-up ranged from six months to 10.7 years (median 12 months). Most studies (23/35) evaluated multifactorial interventions, which included therapies with multiple therapeutic components. Ten studies examined psychological interventions targeted at people with a confirmed psychopathology at baseline and two trials recruited people with a psychopathology or another selecting criterion (or both). Of the remaining 23 trials, nine studies recruited unselected participants from cardiac populations reporting some level of psychopathology (3.8% to 53% with depressive symptoms, 32% to 53% with anxiety), 10 studies did not report these characteristics, and only three studies excluded people with psychopathology.Moderate quality evidence showed no risk reduction for total mortality (risk ratio (RR) 0.90, 95% confidence interval (CI) 0.77 to 1.05; participants = 7776; studies = 23) or revascularisation procedures (RR 0.94, 95% CI 0.81 to 1.11) with psychological therapies compared to usual care. Low quality evidence found no risk reduction for non-fatal MI (RR 0.82, 95% CI 0.64 to 1.05), although there was a 21% reduction in cardiac mortality (RR 0.79, 95% CI 0.63 to 0.98). There was also low or very low quality evidence that psychological interventions improved participant-reported levels of depressive symptoms (standardised mean difference (SMD) -0.27, 95% CI -0.39 to -0.15; GRADE = low), anxiety (SMD -0.24, 95% CI -0.38 to -0.09; GRADE = low), and stress (SMD -0.56, 95% CI -0.88 to -0.24; GRADE = very low).There was substantial statistical heterogeneity for all psychological outcomes but not clinical outcomes, and there was evidence of small-study bias for one clinical outcome (cardiac mortality: Egger test P = 0.04) and one psychological outcome (anxiety: Egger test P = 0.012). Meta-regression exploring a limited number of intervention characteristics found no significant predictors of intervention effects for total mortality and cardiac mortality. For depression, psychological interventions combined with adjunct pharmacology (where deemed appropriate) for an underlying psychological disorder appeared to be more effective than interventions that did not (ß = -0.51, P = 0.003). For anxiety, interventions recruiting participants with an underlying psychological disorder appeared more effective than those delivered to unselected populations (ß = -0.28, P = 0.03). AUTHORS' CONCLUSIONS: This updated Cochrane Review found that for people with CHD, there was no evidence that psychological treatments had an effect on total mortality, the risk of revascularisation procedures, or on the rate of non-fatal MI, although the rate of cardiac mortality was reduced and psychological symptoms (depression, anxiety, or stress) were alleviated; however, the GRADE assessments suggest considerable uncertainty surrounding these effects. Considerable uncertainty also remains regarding the people who would benefit most from treatment (i.e. people with or without psychological disorders at baseline) and the specific components of successful interventions. Future large-scale trials testing the effectiveness of psychological therapies are required due to the uncertainty within the evidence. Future trials would benefit from testing the impact of specific (rather than multifactorial) psychological interventions for participants with CHD, and testing the targeting of interventions on different populations (i.e. people with CHD, with or without psychopathologies).

Quality of life of patients who undergone myocardial revascularization surgery.

OBJECTIVE: to evaluate the quality of life of patients who underwent revascularization surgery. METHOD: a descriptive, cross sectional study, with quantitative approach carried out with 75 patients. The questionnaire WHOQOL-Bref was used to evaluate the quality of life (QOL). RESULTS: patients' QOL evaluation presented a moderate result, with need of improvement of all domains. Low income patients had the worst evaluation of QOL in the domain environment (p=0,021), and the ones from Recife/metropolitan area, in the domain social relationship (p=0,021). Smoker (p=0,047), diabetic (p=0,002) and alcohol consumption (p=0,035) patients presented the worst evaluation of the physical domain. Renal patients presented the worst evaluation of QOL in the physical (P=0,037), psychological (p=0,008), social relationship (p=0,006) domains and total score (p=0,009). CONCLUSION: the improvement of QOL depends on the individual's process of behavioral change and the participation of health professionals is essential to formulate strategies to approach these patients, especially concerning health education.

Expectativas de pacientes submetidos à cirurgia de revascularização do miocárdio no momento da alta hospitalar / Expectativas de los pacientes sometidos a cirugía de revascularización miocárdica en el momento del alta hospitalaria / Expectations of patients submitted to myocardial revascularization surgery at the time of hospital discharge

Objective: recognizing the expectations of patients submitted to myocardium revascularization surgery at the time of hospital discharge. Method: a descriptive-exploratory study of aqualitative approach carried out with ten patients in post-operative myocardium revascularization surgery of a university hospital in the south of Brazil. The data were collected from July to August, 2012, through a semi-structured interview and were analyzed based on content analysis. Results: the results were grouped into a category that focuses on patients ' expectations facing the recovery process and returning to daily activities. It was found out that this phase is challenging for the subjects, in special with feelings of anxiety and worry about the future, besides having weaknesses in relation to the knowledge about changes of habits imposed by the process of illness. Conclusions: surgery causes a significant impact on the patients’ lives, thus being necessary the effective intervention by the nursing staff, in order to optimizing the recovery process.

Motivation is a crucial factor for adherence to a healthy lifestyle among people with coronary heart disease after percutaneous coronary intervention.

AIM: To test the Theory of Adherence of People with Chronic Disease with regard to adherence to treatment among patients with coronary heart disease after a percutaneous coronary intervention. BACKGROUND: Increased knowledge of the concept of adherence is needed for the development of nursing interventions and nursing guidelines for patients with coronary heart disease. DESIGN: A cross-sectional, multi-centre study. METHODS: This study was conducted from February-December 2013 with 416 patients with coronary heart disease 4 months after undergoing a percutaneous coronary intervention. A self-reported questionnaire was used to assess their adherence to treatment. Data were analysed using structural equation modelling. RESULTS: The theory explained 45% of the adherence to a healthy lifestyle and 7% of the adherence to medication. Structural equation modelling confirmed that motivation and results of care had the highest association with adherence to a healthy lifestyle. Responsibility was associated with adherence to medication. Support from next of kin, support from nurses and physicians, and motivation, co-operation, fear of complications and a sense of normality were associated with adherence. CONCLUSION: Patients who are motivated to perform self-care and consider the results of care to be important were more likely to adhere to a healthy lifestyle. Responsible patients were more likely to adhere to their medication. It is important to account for these elements as a part of secondary prevention strategies among patients with coronary heart disease after a percutaneous coronary intervention.

[Evaluation of the clinical, psychological and socio-environmental factors, affecting disability of elderly people undergoing surgical myocardial revascularization].

Factors significant for clinical-and-labor prognosis in elderly patients with ischemic heart disease after surgical myocardial revascularization are considered in the article. The authors demonstrate that for each level of the problem there are their own significant factors. Besides, the most essential correlations between investigated factors are marked out. The results obtained will enable to determine more correctly clinical-and-labor prognosis for patients with ischemic heart disease and develop their efficient rehabilitation programs. It is demonstrated that elderly patients have some features of vital activity restriction which are necessary to take into account while medical social expertise and rehabilitation program development.

[Informed consent for patients undergoing surgery for ischemic cardiomyopathy].

The prognosis of patients with ischemic cardiomyopathy after medical treatment remains poor, despite advances in various therapeutic strategies. In addition to the poorer prognosis, they face higher operative risk, and complex, unestablished operative procedures should be addressed when obtaining preoperative informed consent from patients with ischemic cardiomyopathy. Although the established indications for revascularization in patients with ischemic heart failure pertain to those with angina and significant coronary artery disease, the management of patients with ischemic heart failure without angina is a challenge because of the lack of evidence in this population. The possibility of combining myocardial revascularization with surgical ventricular reconstruction (SVR) to reverse left ventricular remodeling or with mitral valve plasty to repair the incompetence of mitral valve coaptation has been examined in many trials, although little difference in the long-term outcomes between the simple revascularization and the combined procedure groups have been observed. The therapeutic guidelines for patients with ischemic cardiomyopathy state that choosing to add SVR and/or mitral surgery to revascularization should be based on a precise, careful evaluation and should be performed only by surgeons with a high level of surgical expertise.

What do patients think about while waiting for myocardial revascularization?

OBJECTIVES: Coronary artery disease constitutes a public health issue involving high mortality rates. The objectives of this study were to evaluate the feelings and perception of patients hospitalized before myocardial revascularization and to explore doctor-patient interactions before cardiac surgery with special attention to existential challenges. STUDY DESIGN: A qualitative, exploratory study involving patients admitted to a university teaching hospital in the city of Salvador, Bahia, Brazil, awaiting myocardial revascularization. METHODS: The data were obtained from in-depth interviews that followed a previously defined script based on the study objectives. The data collected at each interview were allocated into content blocks in common with the selected categories and illustrated by quotations from the patients' speech. Twelve patients were interviewed. Data collection was closed when saturation was achieved, in the sense that new main issues did not appear in subsequent dialogues. RESULTS: The various strategies used by the patients to administer their emotions during the period preceding myocardial revascularization highlight the importance that factors of a subjective nature acquire at this specific time in their lives. The patients recognized the benefit of being able to discuss their heart problems as a means of diminishing their fear and anxiety. CONCLUSIONS: It is vital for the medical team to be more supportive and understanding concerning the emotions experienced by the patients in the period preceding myocardial revascularization. This study emphasizes the importance of the task of helping patients administer their perceptions and feelings and even planning their life while awaiting myocardial revascularization.

Understanding the process of living as signified by myocardial revascularization surgery patients.

OBJECTIVE: To understand the meanings for the process of living, for patients undergoing myocardial revascularization surgery, and to construct an explanatory theoretical model. METHOD: Grounded Theory was used, with data collection undertaken between October 2010 and May 2012, in a health institution which specializes in cardiac surgery, located in the south of Brazil. Thirty-three subjects were interviewed (patients, health care professionals and family members), distributed in four sample groups. RESULT: The explanatory theoretical model was comprised of 11 categories and the central phenomenon. The specialized service and the cardiac rehabilitation program formed the context, the discovery of the cardiac disease and the feelings experienced during the perioperative period were the cause and intervening conditions in the process of experiencing the myocardial revascularization surgery. The strategies were relying on the family's support, having faith and hope, and participating in the rehabilitation program. This process's main consequences were the confrontation of the changes and the resulting limitations, difficulties and adaptations to the new lifestyle after surgery. CONCLUSION: The process of experiencing the myocardial revascularization surgery constitutes an opportunity for maintaining the patient's life associated with the needs for confronting the significant changes in lifestyle.

OBJETIVO: compreender os significados sobre o processo de viver para pacientes submetidos a cirurgia de revascularização do miocárdio, e construir um modelo teórico explicativo. MÉTODO: utilizou-se a Teoria Fundamentada nos Dados, com coleta dos dados realizada de outubro/2010 a maio/2012, numa instituição de saúde referência em cirurgia cardíaca, localizada no Sul do Brasil. Entrevistaram-se 33 sujeitos (pacientes, profissionais de saúde e familiares), distribuídos em 4 grupos amostrais. RESULTADO: o modelo teórico explicativo foi constituído por 11 categorias e pelo fenômeno central. O serviço de referência e o programa de reabilitação cardíaca formaram o contexto, a descoberta da doença cardíaca e os sentimentos vivenciados, durante o período perioeratório, foram causa e condições interventoras no processo de viver a cirurgia de revascularização do miocárdio. As estratégias foram contar com apoio da família, ter fé, esperança e participar do programa de reabilitação. As principais consequências desse processo foram o enfrentamento das mudanças e consequentes limitações, dificuldades e adaptações ao novo estilo de vida, após a cirurgia. CONCLUSÃO: o processo de viver a cirurgia de revascularização do miocárdio se configura como oportunidade para a manutenção da vida do paciente, associada às necessidades de enfrentamento das significativas mudanças no estilo de vida.

A history of heart interventions moderates the relationship between psychological variables and the presence of chest pain in older women with self-reported coronary heart disease.

OBJECTIVES: This study examines the hypothesis that a past history of heart interventions will moderate the relationship between psychosocial factors (stressful life events, social support, perceived stress, having a current partner, having a past diagnosis of depression or anxiety over the past 3 years, time pressure, education level, and the mental health index) and the presence of chest pain in a sample of older women. DESIGN: Longitudinal survey over a 3-year period. METHODS: The sample was taken from a prospective cohort study of 10,432 women initially aged between 70 and 75 years, who were surveyed in 1996 and then again in 1999. Two groups of women were identified: those reporting to have heart disease but no past history of heart interventions (i.e., coronary artery bypass graft/angioplasty) and those reporting to have heart disease with a past history of heart interventions. RESULTS: Binary logistic regression analysis was used to show that for the women with self-reported coronary heart disease but without a past history of heart intervention, feelings of time pressure as well as the number of stressful life events experienced in the 12 months prior to 1996 were independent risk factors for the presence of chest pain, even after accounting for a range of traditional risk factors. In comparison, for the women with self-reported coronary heart disease who did report a past history of heart interventions, a diagnosis of depression in the previous 3 years was the significant independent risk factor for chest pain even after accounting for traditional risk factors. CONCLUSION: The results indicate that it is important to consider a history of heart interventions as a moderator of the associations between psychosocial variables and the frequency of chest pain in older women.
