High-sensitivity C-reactive protein levels and health status outcomes after myocardial infarction.

ABSTRACT: BACKGROUND AND AIMS:While high-sensitivity C-reactive protein (hs-CRP) is a marker of inflammation and higher cardiovascular risk, its association with health status (symptoms, function and quality of life) after acute myocardial infarction (AMI) is unknown. METHODS:Among 3410 patients with AMI from the TRIUMPH (N = 1301) and VIRGO (N = 2109) studies, we compared 1-year generic (Medical Outcome Study Short Form-12 and Euro Quality of Life Visual Analog Scale) and disease-specific (Seattle Angina Questionnaire) health status outcomes in those with hs-CRP ?2 mg/L vs. <2 mg/L. In hierarchical linear regression models, we examined the association of 30-day hs-CRP levels with 1-year health status without adjustment, after adjusting for 30-day health status, and after adjusting for demographic, socioeconomic, disease severity/comorbidities and treatment characteristics. RESULTS:The median (25th, 75th percentiles) 30-day hs-CRP was 2.6 (1.1, 6.1) mg/L and 59% had hs-CRP ?2 mg/L. Statin therapy was used in 92% of patients at hospital discharge. Thirty-day hs-CRP ?2 mg/L was inversely associated with all 1-year health status measures in unadjusted and partially adjusted models, but not in fully-adjusted models. Results were similar when hs-CRP was analyzed as a continuous variable. CONCLUSIONS:While elevated hs-CRP 30 days after AMI was associated with worse health status in unadjusted analyses, this was not significant after adjusting for comorbidities, suggesting that hs-CRP may be a marker of comorbidities associated with worse health status. Whether reducing inflammation in AMI patients will improve health status should be tested in ongoing trials.

Project description:ObjectivesThis study sought to determine the association of chronic stress with long-term adverse outcomes after acute myocardial infarction (AMI).BackgroundChronic stress has been shown to be associated with the development of cardiovascular disease and, in the case of particular types of stress such as job and marital strain, with recurrent adverse events after AMI. Little is known, however, about the association of chronic stress with mortality and adverse health status outcomes in a general AMI population.MethodsIn a cohort of 4,204 AMI patients from 24 U.S. hospitals completing the Perceived Stress Scale-4 (sum scores ranging from 0 to 16) during hospitalization, moderate/high stress over the previous month was defined as scores in the top 2 quintiles (scores of 6 to 16). Detailed data on sociodemographics, psychosocial status, and clinical characteristics were collected at baseline. Outcomes included patients' 1-year health status, assessed with the Seattle Angina Questionnaire, Short Form-12, and EuroQol Visual Analog Scale, and 2-year mortality.ResultsAMI patients with moderate/high stress had increased 2-year mortality compared with those having low levels of stress (12.9% vs. 8.6%; p < 0.001). This association persisted after adjusting for sociodemographics, clinical factors (including depressive symptoms), revascularization status, and GRACE (Global Registry of Acute Coronary Events) discharge risk scores (hazard ratio: 1.42: 95% confidence interval: 1.15 to 1.76). Furthermore, moderate/high stress was independently associated with poor 1-year health status, including a greater likelihood of angina, worse disease-specific and generic health status, and worse perceived health (p < 0.01 for all).ConclusionsModerate/high perceived stress at the time of an AMI is associated with adverse long-term outcomes, even after adjustment for important confounding factors. Future studies need to examine whether stress mediates observed racial and socioeconomic disparities and whether novel interventions targeting chronic stress and coping skills can improve post-AMI outcomes.

Project description:ImportanceCardiac rehabilitation (CR) improves survival after acute myocardial infarction (AMI), and referral to CR has been introduced as a performance measure of high-quality care. The association of participation in CR with patients' health status (eg, quality of life, symptoms, and functional status) is poorly defined.ObjectiveTo examine the association of participation in CR with health status outcomes after AMI.Design, setting, and participantsA retrospective cohort study was conducted of patients enrolled in 2 AMI registries: PREMIER, from January 1, 2003, to June 28, 2004, and TRIUMPH, from April 11, 2005, to December 31, 2008. The analytic cohort was restricted to 4929 patients with data available on baseline health status, 6- or 12- month follow-up health status, and participation in CR. Data analysis was performed from 2014 to 2015.ExposuresParticipation in at least 1 CR session within 6 months of hospital discharge.Main outcomes and measuresPatient health status was quantified using the Seattle Angina Questionnaire (SAQ) and the 12-Item Short-Form Health Survey (SF-12). The primary outcomes of interest were the mean differences in SAQ domain scores during the 12 months after AMI between patients who did and did not participate in CR. Secondary outcomes were the mean differences in the SF-12 summary scores and all-cause mortality.ResultsAfter successfully matching the cohorts of the 4929 patients (3328 men and 1601 women; mean [SD] age, 60.0 [12.2] years) for the propensity to participate in CR and comparing the groups using linear, mixed-effects models, mean differences in the SAQ and SF-12 domain scores were similar at 6 and 12 months between the 2012 patients participating in CR (3 were unable to be matched) and the 2894 who did not participate (20 were unable to be matched). At 6 months, the mean difference was -0.76 (95% CI, -2.05 to 0.52) for the SAQ quality of life score, -1.53 (95% CI, -2.57 to -0.49) for the SAQ angina frequency score, 0.38 (95% CI, -0.51 to 1.27) for the SAQ treatment satisfaction score, -0.42 (95% CI, -1.65 to 0.79) for the SAQ physical limitation score, 0.50 (95% CI, -0.22 to 1.22) for the SF-12 physical component score, and 0.13 (95% CI, -0.53 to 0.79) for the SF-12 mental component score. At 12 months, the mean difference was -0.89 (95% CI, -2.20 to 0.43) for the SAQ quality of life score, -1.05 (95% CI, -2.12 to 0.02) for the SAQ angina frequency score, 0.38 (95% CI, -0.54 to 1.29) for the SAQ treatment satisfaction score, -0.14 (95% CI, -1.41 to 1.14) for the SAQ physical limitation score, 0.17 (95% CI, -0.57 to 0.92) for the SF-12 physical component score, and 0.12 (95% CI, -0.56 to 0.80) for the SF-12 mental component score. In contrast, the hazard rate of all-cause mortality (up to 7 years) associated with participating in CR was 0.59 (95% CI, 0.46-0.75).Conclusions and relevanceIn a cohort of 4929 patients with AMI, we found that those who did and did not participate in CR had similar reported health status during the year following AMI; however, participation in CR did confer a significant survival benefit. These findings underscore the need for increased use of validated patient-reported outcome measures to further examine if and how health status can be maximized for patients who participate in CR.
