Sex differences in perceived stress and early recovery in young and middle-aged patients with acute myocardial infarction.

ABSTRACT: Younger age and female sex are both associated with greater mental stress in the general population, but limited data exist on the status of perceived stress in young and middle-aged patients presenting with acute myocardial infarction.We examined sex difference in stress, contributing factors to this difference, and whether this difference helps explain sex-based disparities in 1-month recovery using data from 3572 patients with acute myocardial infarction (2397 women and 1175 men) 18 to 55 years of age. The average score of the 14-item Perceived Stress Scale at baseline was 23.4 for men and 27.0 for women (P<0.001). Higher stress in women was explained largely by sex differences in comorbidities, physical and mental health status, intrafamily conflict, caregiving demands, and financial hardship. After adjustment for demographic and clinical characteristics, women had worse recovery than men at 1 month after acute myocardial infarction, with mean differences in improvement score between women and men ranging from -0.04 for EuroQol utility index to -3.96 for angina-related quality of life (P<0.05 for all). Further adjustment for baseline stress reduced these sex-based differences in recovery to -0.03 to -3.63, which, however, remained statistically significant (P<0.05 for all). High stress at baseline was associated with significantly worse recovery in angina-specific and overall quality of life, as well as mental health status. The effect of baseline stress on recovery did not vary between men and women.Among young and middle-aged patients, higher stress at baseline is associated with worse recovery in multiple health outcomes after acute myocardial infarction. Women perceive greater psychological stress than men at baseline, which partially explains women's worse recovery.

Project description:BACKGROUND:Sex differences are known to exist in the management of older patients presenting with acute myocardial infarction (AMI). Few studies have examined the incidence and risk factors of AMI among young patients, or whether clinical management differs by sex. METHODS:The Atherosclerosis Risk in Communities (ARIC) Surveillance study conducts hospital surveillance of AMI in 4 US communities (MD, MN, MS, and NC). AMI was classified by physician review, using a validated algorithm. Medications and procedures were abstracted from the medical record. Our study population was limited to young patients aged 35 to 54 years. RESULTS:From 1995 to 2014, 28?732 weighted hospitalizations for AMI were sampled among patients aged 35 to 74 years. Of these, 8737 (30%) were young. The annual incidence of AMI hospitalizations increased for young women but decreased for young men. The overall proportion of AMI admissions attributable to young patients steadily increased, from 27% in 1995 to 1999 to 32% in 2010 to 2014 ( P for trend=0.002), with the largest increase observed in young women. History of hypertension (59% to 73%, P for trend<0.0001) and diabetes mellitus (25% to 35%, P for trend<0.0001) also increased among young AMI patients. Compared to young men, young women presenting with AMI were more often black and had a greater comorbidity burden. In adjusted analyses, young women had a lower probability of receiving lipid-lowering therapies (relative risk [RR]=0.87; 95% confidence interval [CI], 0.80-0.94), nonaspirin antiplatelets (RR=0.83; 95% CI, 0.75-0.91), beta blockers (RR=0.96; 95% CI, 0.91-0.99), coronary angiography (RR=0.93; 95% CI, 0.86-0.99) and coronary revascularization (RR = 0.79; 95% CI, 0.71-0.87). However, 1-year all-cause mortality was comparable for women versus men (HR=1.10; 95% CI, 0.83-1.45). CONCLUSIONS:The proportion of AMI hospitalizations attributable to young patients increased from 1995 to 2014 and was especially pronounced among women. History of hypertension and diabetes among young patients admitted with AMI increased over time as well. Compared with young men, young women presenting with AMI had a lower likelihood of receiving guideline-based AMI therapies. A better understanding of factors underlying these changes is needed to improve care of young patients with AMI.

Project description:Compared with older patients, young adults with a history of myocardial infarction (MI) tend to have a higher burden of psychosocial adversity. Exposure to early-life stressors may contribute to the risk of adverse outcomes in this patient population, potentially through inflammatory pathways. To investigate the association of early-life trauma with adverse events and examine whether inflammation plays a role. This cohort study included patients aged 18 to 60 years with a verified history of MI in the past 8 months from a university-affiliated hospital network. Baseline data were collected from June 2011 to March 2016, and follow-up data were obtained through July 2019. Analysis began September 2019. Early-life trauma was assessed using the Early Trauma Inventory-Self Report short form (ETI-SR-SF), both as a continuous and as a binary variable at the threshold of a score of 7 or higher. Inflammatory biomarkers, interleukin 6, and C-reactive protein were obtained at baseline. A composite end point of recurrent MI, stroke, heart failure hospitalization, and cardiovascular death over a median 3-year follow-up. Of 300 patients, the mean (SD) age was 51 (7) years, 198 (66%) were African American, and 150 (50%) were women. Compared with participants with MI with an ETI-SR-SF score less than 7, those with a score of 7 or higher had higher levels of interleukin 6 and C-reactive protein at baseline. Compared with participants with an ETI-SR-SF score less than 7, those with a score of 7 or higher were at a greater risk for adverse outcomes, with a hazards ratio of 2.3 (95% CI, 1.3-3.9). Results remained consistent in multivariable analysis. Further adjustment for C-reactive protein rendered the results no longer statistically significant. Early-life trauma displayed a dose-dependent response when analyzed as a continuous variable and by quartiles. Early-life trauma is an independent risk factor for adverse outcomes in young and middle-aged individuals with a history of MI. Neurobiological mechanisms leading to lifetime activation of systemic inflammatory cascades may be implicated.
