Factors influencing stroke survivors' quality of life during subacute recovery.

BACKGROUND AND PURPOSE: Health-related quality of life (HRQOL) is an important index of outcome after stroke and may facilitate a broader description of stroke recovery. This study examined the relationship of individual and clinical characteristics to HRQOL in stroke survivors with mild to moderate stroke during subacute recovery. METHODS: Two hundred twenty-nine participants 3 to 9 months poststroke were enrolled in a national multisite clinical trial (Extremity Constraint-Induced Therapy Evaluation). HRQOL was assessed using the Stroke Impact Scale (SIS), Version 3.0. The Wolf Motor Function Test documented functional recovery of the hemiplegic upper extremity. Multiple analysis of variance and regression models examined the influence of demographic and clinical variables across SIS domains. RESULTS: Age, gender, education level, stroke type, concordance (paretic arm=dominant hand), upper extremity motor function (Wolf Motor Function Test), and comorbidities were associated across SIS domains. Poorer HRQOL in the physical domain was associated with age, nonwhite race, more comorbidities, and reduced upper-extremity function. Stroke survivors with more comorbidities reported poorer HRQOL in the area of memory and thinking, and those with an ischemic stroke and concordance reported poorer communication. CONCLUSIONS: Although results may not generalize to lower functioning stroke survivors, individual characteristics of persons with mild to moderate stroke may be important to consider in developing comprehensive, targeted interventions designed to maximize recovery and improve HRQOL.

Patterns of referral and recovery in women and men undergoing coronary artery bypass grafting.

This study compares women and men undergoing coronary artery bypass grafting. Factors before and after coronary surgery were examined to identify variables related to mortality and morbidity. The study population included 465 women and 465 men matched for age (mean age 64.2 years) who underwent first time isolated coronary artery bypass grafting between 1983 and 1988. There were higher incidences of systemic hypertension, diabetes mellitus, postmyocardial infarction angina, thyroid gland disease, arthritis (p less than 0.001 for all), acute myocardial infarction (p = 0.03), congestive heart failure (p = 0.03), and emergency surgery (p = 0.02) in women, whereas more men had peptic ulcer disease (p less than 0.001). The in-hospital death rate was not significantly different (women 4.3% vs men 3.7%). For all subjects, emergency surgery (p less than 0.001), significant left main narrowing (p less than 0.05) and renal disease (p less than 0.001) were related to death, whereas history of myocardial infarction (p less than 0.05) and diabetes (p less than 0.05) were related to death only in men. Age and body surface area were not related to death. After surgery men had a higher incidence of atrial arrhythmia (p less than 0.001), and women had a higher incidence of congestive heart failure (p less than 0.001). Although women did not have a higher mortality rate, the data suggest that women and men do not share all the same predictors of mortality after surgery.

Coronary artery bypass graft surgery in older women and men.

OBJECTIVE: To compare women and men younger than 70 years of age and 70 years or older undergoing coronary artery bypass surgery. DESIGN: Retrospective chart review, case-control series. SETTING: University medical center. PATIENTS: All women (n = 465) having first-time isolated coronary artery bypass surgery between 1983 and 1988, and 465 men matched for age and year of surgery. Predominantly white; 33% were 70 years or older. MEASURES: Medical record data: demographics, preoperative comorbidities, perioperative and postoperative complications, mortality, length of stay. RESULTS: Preoperatively, women 70 years of age or older had a higher incidence of congestive heart failure, renal disease and hypertension, and a lower incidence of smoking history compared with women less than 70 years old. Men 70 years or older had a higher incidence of congestive heart failure and renal disease, and a lower incidence of smoking history compared with men less than 70 years old. There was no difference in mortality between older and younger women, whereas the mortality rate for older men was higher than that for younger men. There were fewer differences between women younger than 70 and those 70 years or older in incidence of postoperative complications than between men of those same age groups. Among patients 70 years or older, incidence of postoperative congestive heart failure was greater in women than in men. There were no other differences between women and men younger than 70 and those 70 years or older in incidence of postoperative complications. Controlling for the influence of postoperative complications, age was related to length of stay for women and men. CONCLUSIONS: Older women were at no greater risk of mortality or the occurrence of postoperative complications compared with younger women or older men. A functional component influencing recovery and length of hospital stay needs to be considered to provide optimal nursing care after surgery.

Social comparisons and temporal comparisons after coronary artery surgery.

OBJECTIVE: To examine the use and efficacy of social and temporal comparisons used before and after coronary artery surgery. DESIGN: Secondary analysis of data from a prospective study designed to examine social support. PATIENTS: 141 subjects undergoing surgery. RESULTS: One third of subjects made spontaneous social comparisons. Most who made a social comparison before and 1 month after surgery viewed themselves as similar to others. Social comparisons were related to mood states only before surgery. The majority of subjects made temporal comparisons 1 year after surgery. Subjects generally saw themselves as the same or better than they were before surgery. Temporal comparisons were related to both emotional and functional outcomes. CONCLUSIONS: Social comparisons were not consistently related to emotional and functional status; thus whether they can be used to formulate interventions needs further exploration. On the other hand, use of temporal comparisons was related to better mood state and functional status. Enhancing an individual's ability to view self as stable or improved compared with before surgery may be beneficial. Results are discussed in terms of how social comparison theory fits within the overall context of coping with physical illness.
