Periprocedural Stroke and Myocardial Infarction as Risks for Long-Term Mortality in CREST.

ABSTRACT: BACKGROUND:The Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) previously reported increased mortality in patients who sustained a periprocedural stroke or cardiac event (myocardial infarction [MI] or biomarker only) in follow-up to 4 years. We now extend these observations to 10 years. METHODS AND RESULTS:CREST is a randomized controlled trial designed to compare the outcomes of carotid stenting versus carotid endarterectomy. Proportional hazards models were used to assess the association between mortality and periprocedural stroke, MI, or biomarker-only events. For 10-year follow-up, patients with periprocedural stroke were at 1.74× the risk of death compared with those without stroke (adjusted hazard ratio [HR]=1.74; 95% CI, 1.21-2.50; P<0.003). This increased risk was driven by increased early (between 0 and 90 days) mortality (adjusted HR=14.41; 95% CI, 5.33-38.94; P<0.0001), with no significant increase in late (between 91 days and 10 years) mortality (adjusted HR=1.40; 95% CI, 0.93-2.10; P=0.11). Patients with a protocol MI were at 3.61× increased risk of death compared with those without MI (adjusted HR=3.61; 95% CI, 2.28-5.73; P<0.0001), with an increased hazard both early (adjusted HR=8.20; 95% CI, 1.86-36.2; P=0.006) and late (adjusted HR=3.40; 95% CI, 2.09-5.53; P<0.0001). Patients with a biomarker-only event were at 2.04× increased risk overall (adjusted HR=2.04; 95% CI, 1.09-3.84; P=0.03) than those without MI, with an increased early hazard (adjusted HR=8.44; 95% CI, 1.09-65.5; P=0.04) and a suggestive but nonsignificant association toward higher 91-day to 10-year risk (1.88; 95% CI, 0.97-3.64; P=0.062) contributing to the increased risk. CONCLUSIONS:In the CREST trial, patients with periprocedural events demonstrate a substantial increase in future mortality to 10 years. For stroke, this risk is largely confined to an early time frame while periprocedural MI or biomarker-only events confer a continuous increased mortality for 10 years. Strategies to reduce periprocedural events and to optimize the evaluation and management of patients with cardiac events should be considered in efforts to reduce not only early but also long-term mortality.

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.
