Self-assessed physical health predicts 10-year mortality after myocardial infarction.
ABSTRACT In spite of their widespread use in other fields, global measures of health are not commonly used in determining the prognosis of patients with myocardial infarction (MI). The objective of the present study was to ascertain the relationship between self-assessed physical health at the time of the MI and long-term mortality.
This was a prospective cohort study of 284 patients with MI admitted to an academic community hospital between July 1995 and December 1996 who completed the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The physical component scale from the SF-36 was used as a self-assessment of physical health. All-cause mortality was assessed 10 years later by using the Social Security Death Index.
Patients with lower self-reported physical health were significantly more likely to be women; older; depressed; have a history of coronary artery disease; have a family history of MI; have a non-Q wave MI; have a Killip class 3 or 4 MI; have hypertension, diabetes mellitus, renal insufficiency, and chronic obstructive pulmonary disease; and have a longer hospitalization period. Patients with higher physical component scores had significantly lower mortality in the 10 years after MI and this persisted after adjusting for confounders (hazard ratio = 0.97 [95% CI 0.96-0.99], P = .001).
These data suggest that self-assessed physical health provides information on the long-term prognosis of patients with MI above and beyond that provided by traditional risk predictors.

ABSTRACT: Background Physical and Mental Component Summary (PCS, MCS, respectively) scales of SF- 36 health-related-quality-of-life have been associated with all-cause and cardiovascular disease (CVD) mortality. Their relationships with CVD incidence are unclear. This study purpose was to test whether PCS and/or MCS were associated with CVD incidence and death. Methods Postmenopausal women (aged 50–79 years) in control groups of the Women’s Health Initiative clinical trials (n = 20,308) completed the SF-36 and standardized questionnaires at trial entry. Health outcomes, assessed semi-annually, were verified with medical records. Cox regressions assessed time to selected outcomes during the trial phase (1993–2005). Results A total of 1075 incident CVD events, 204 CVD-specific deaths, and 1043 total deaths occurred during the trial phase. Women with low versus high baseline PCS scores had less favorable health profiles at baseline. In multivariable models adjusting for baseline confounders, participants in the lowest PCS quintile (reference = highest quintile) exhibited 1.8 (95%CI: 1.4, 2.3), 4.7 (95%CI: 2.3, 9.4), and 2.1 (95%CI: 1.7, 2.7) times greater risk of CVD incidence, CVD-specific death, and total mortality, respectively, by trial end; whereas, MCS was not significantly associated with CVD incidence or death. Conclusion Physical health, assessed by self-report of physical functioning, is a strong predictor of CVD incidence and death in postmenopausal women; similar self-assessment of mental health is not. PCS should be evaluated as a screening tool to identify older women at high risk for CVD development and death.BMC Public Health 05/2013; 13(1):468. DOI:10.1186/1471-2458-13-468 · 2.26 Impact Factor

ABSTRACT: Self-reported health-related quality of life (HRQL) and changes in HRQL have been shown to predict mortality and/or adverse events in patients with coronary artery disease. MacNew Heart Disease HRQL questionnaire scores were examined as predictors of 4-year all-cause mortality. Following referral for angioplasty in 385 patients with coronary artery disease, data were analyzed for differences in all-cause mortality by MacNew Global and subscale baseline and 1- and 3-month change scores (deteriorated ≥0.50; unchanged (-0.49 to +0.49); and improved ≥0.50 points). Mean baseline, 1-month, and 3-month MacNew Global and subscale scores were similar in survivors and non-survivors. Mean 1- and 3-month Global and emotional subscale and mean 1-month social subscale change scores decreased more in non-survivors than survivors. Compared with patients whose Global MacNew HRQL scores improved at one month, 4-year all-cause mortality hazard ratio (HR) was higher in patients whose HRQL deteriorated (HR, 1.70, 95% CI, 1.09, 2.65; p=0.021). Compared with patients whose Global MacNew HRQL improved at three months, 4-year all-cause mortality was higher in both patients whose HRQL had deteriorated (HR, 2.07, 95% CI, 1.29, 3.32; p=0.003) and patients with unchanged HRQL (HR, 2.62, 95% CI, 1.11, 6.17; p=0.028). A deterioration of ≥0.50 points in MacNew HRQL Global scores at both one and three months is predictive of 4-year all-cause mortality. Serial HRQL information may be useful to identify patients at higher risk for adverse cardiac events and mortality and may have implications for determining follow-up frequency and treatment in individual patients.International journal of cardiology 03/2014; 174(1).
