Health insurance, perceived threat, and posttraumatic stress after suspected acute coronary syndrome

OBJECTIVE

Threat perceptions during evaluation for acute coronary syndrome (ACS) in the emergency department (ED) predict posttraumatic stress symptoms (PSS). It is unknown how health insurance status affects threat perceptions. We tested whether lacking health insurance is associated with higher threat perceptions and PSS in patients with suspected ACS in the ED and whether threat perceptions mediate associations between lack of health insurance and subsequent PSS.

METHOD

Patients in the Columbia University Irving Medical Center ED with suspected ACS enrolled in an observational cohort study of psychological and cardiovascular outcomes. A multivariable linear regression model tested health insurance status as the predictor of ED threat perceptions and PSS 1-month posthospitalization, adjusting for age, gender, education, Charlson Comorbidity Index, and Global Registry of Acute Coronary Events risk score. A bootstrapped mediation model tested health insurance status as the predictor, PSS 1-month posthospitalization as the outcome, and ED threat perceptions as the mediator, with the same covariates.

RESULTS

Of 1,741 patients with suspected ACS in the ED (Mage = 61.01 years, SD = 13.27; 47.1% women), a plurality identified as "Other" race (36.1%), Black (23.9%), and White (22.4%), and 10.3% of patients were uninsured. Lack of health insurance was associated with greater threat perceptions, b = -0.16, 95% CI [-0.26, -0.06], p = .002. Threat perceptions mediated the association between lack of health insurance and higher 1-month PSS, indirect effect = -1.04, 95% CI [-1.98, -0.17].

CONCLUSIONS

Lacking health insurance may heighten threat perceptions during ACS evaluation, which may put patients at risk of developing PSS. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Association between cardiac event-induced PTSD symptoms and daily intrusive thoughts about cardiac risk: An ecological momentary assessment study

OBJECTIVE

Posttraumatic stress symptoms (PSS) due to acute cardiac events are common and may lead patients to avoid secondary prevention behaviors. However, patients' daily experience of cardiac event-induced PSS has not been studied after a potentially traumatic cardiac hospitalization.

METHOD

In an observational cohort study, 108 mostly male patients with coronary heart disease were recruited after evaluation for suspected acute coronary syndrome (ACS). One month later, PSS were assessed via telephone-administered PTSD Checklist for DSM-5 (PCL-5). The exposure of interest was elevated (PCL-5 ≥ 20) vs. non-elevated PSS (PCL-5 ≤ 5). The occurrence and severity of cardiac-related intrusive thoughts were assessed 5 times daily for 2 weeks via electronic surveys on a wrist-worn device.

RESULTS

Moderate-to-severe intrusive thoughts were experienced by 48.1% of patients but more commonly by elevated-PSS (n = 36; 66.7%) than non-elevated-PSS (n = 72; 38.9%) patients. After adjustment for demographic and clinical characteristics, elevated- vs. non-elevated-PSS patients had a 9-fold higher odds of experiencing a moderate-to-severe intrusive thought during each 2-h assessment interval (adjusted OR = 9.14, 95% CI [2.99, 27.92], p < .01). After adjustment, intrusive thoughts on a 0-to-6 point scale were over two times as intense for elevated-PSS vs. non-elevated-PSS patients.

CONCLUSIONS

Intrusive thoughts about cardiac risk were common in patients recently evaluated for ACS, but much more prevalent and intense in those with elevated vs non-elevated PSS.

Abstract P571: Investigating Factors Relevant to Understanding the Hispanic Health Paradox in Patients After Cardiac Arrest

Introduction: The growing Hispanic community faces disproportionate hardship due to lower financial capital and educational opportunity. The Hispanic health paradox refers to the finding that Hispanics tend to have better cardiovascular outcomes than non-Hispanics, despite facing greater hardships and more cardiovascular risk factors. Behavioral (e.g., sleep) and psychological (e.g., optimism) factors predict recovery after acute coronary syndrome events, but less is known about how these factors differ by ethnicity after cardiac arrest (CA). We tested demographic, psychological, behavioral, and recovery factors that may underlie the Hispanic health paradox among CA survivors.

Hypothesis: We hypothesized that Hispanic vs. non-Hispanic cardiac arrest survivors would have lower income and education but would not differ in behavioral, psychological, and recovery factors.

Methods: An observational cohort study, Psychological predictors of recovery after an Acute Cardiac Event (PACE) , enrolled 68 neurologically intact CA survivors admitted to NewYork-Presbyterian Hospital. At hospital discharge, self-reported demographic, psychological, behavioral, and recovery variables were assessed. Independent-samples t-tests of Hispanic vs. non-Hispanic CA survivors were conducted comparing income, education, posttraumatic stress symptoms, depression, negative affect, cardiac anxiety, optimism, positive affect, social support, sleep, physical activity, independent activities of daily living, and self-maintenance.

Results: As hypothesized, Hispanic vs. non-Hispanic participants had lower income, Mann Whitney U = 99.00, z = -3.46, p < .01, and lower education, Mann Whitney U = 336.00, z = -2.65, p = .01. Unexpectedly, Hispanic patients reported greater cardiac anxiety M = 39.60, SD = 16.70) than non-Hispanic patients ( M = 30.29, SD = 11.67), t (66) = -2.722, p = .008. No other tested factors were significant, all p s ≥ .419.

Conclusions: Cardiac anxiety is the only tested variable that differed by ethnicity. While Hispanic ethnicity may be protective for certain aspects of cardiovascular health, the present findings indicate that Hispanic CA survivors experience higher psychological distress, which itself is a known risk factor for poor health behaviors. Future research should assess potential drivers of cardiac anxiety (e.g., mistrust of healthcare system, poor patient-physician communication). Future intervention research should target heart-related fear during CA recovery.

Relationship between NIH stroke symptoms and post-traumatic stress disorder in patients evaluated for transient ischemic attack/stroke

OBJECTIVE

Post-traumatic stress disorder (PTSD) can develop after a life-threatening medical event. According to the enduring somatic treat (EST) model, internal somatic cues (e.g., rapid heart rate) may contribute to symptoms of stroke/TIA-induced PTSD. To address this possibility, the present study tested the association of stroke-induced disability with PTSD symptoms in patients treated for stroke or transient ischemic attack (TIA).

METHOD

Participants (n = 300) were drawn from an observational cohort study examining PTSD symptoms in patients admitted to the NewYork Presbyterian Hospital between 2015 and 2017 for a stroke/TIA. Patients self-reported acute stress symptoms in-person approximately 3 days post-stroke/TIA and PTSD symptoms via telephone one month later. Severity of stroke symptoms (i.e., stroke disability) was evaluated using the NIH Stroke Scale prior to hospital discharge.

RESULTS

Stroke disability had a significant, positive association with acute stress symptoms early post-stroke/TIA, B = 0.46, se = 0.15, p = .002, and with PTSD symptoms one month later, B = 0.56, se = 0.19, p = .003.

CONCLUSIONS

Stroke disability is positively associated with both acute distress and PTSD symptoms one month later following a stroke/TIA, supporting the hypothesis that internal somatic symptoms contribute to the development stroke/TIA-induced PTSD symptoms.
