RESUMO
OBJECTIVE: Negative emotional states, such as anger and anxiety, are associated with the onset of myocardial infarction and other acute clinical manifestations of ischemic heart disease. The likelihood of experiencing these short-term negative emotions has been associated with long-term psychological background factors such as depression, generalized anxiety, and personality factors. We examined the association of acute emotional states preceding cardiac stress testing (CST) with inducibility of myocardial ischemia and to what extent psychological background factors account for this association. METHODS: Emotional states were assessed in patients undergoing CST (n = 210; mean [standard deviation] age = 66.9 [8.2] years); 91 (43%) women) using self-report measures and video recordings of facial emotion expression. Video recordings were analyzed for expressed anxiety, anger, sadness, and happiness before CST. Psychological background factors were assessed with validated questionnaires. Single-photon emission computed tomography was used to evaluate inducibility of ischemia. RESULTS: Ischemia occurred in 72 patients (34%). Emotional states were not associated with subsequent inducibility of ischemia during CST (odds ratio between 0.93 and 1.04; p values > .50). Psychological background factors were also not associated with ischemia (odds ratio between 0.96 and 1.06 per scale unit; p values > .20) and did not account for the associations of emotional states with ischemia. CONCLUSIONS: Emotional states immediately before CST and psychological background factors were not associated with the inducibility of ischemia. These findings indicate that the well-documented association between negative emotions with acute clinical manifestations of ischemic heart disease requires a different explanation than a reduced threshold for inducible ischemia.

BACKGROUND: Patients with myocardial ischemia in the absence of obstructive coronary artery disease (CAD) often experience anginal complaints and are at risk of cardiac events. Stress-related psychological factors and acute negative emotions might play a role in these patients with suspect coronary microvascular dysfunction (CMD). METHODS AND RESULTS: 295 Patients (66.9 ± 8.7 years, 46% women) undergoing myocardial perfusion single-photon-emission computed tomography (MPI-SPECT), were divided as follows: (1) a non-ischemic reference group (n = 136); (2) patients without inducible ischemia, but with a history of CAD (n = 62); (3) ischemia and documented CAD (n = 52); and (4) ischemia and suspect CMD (n = 45). These four groups were compared with regard to psychological factors and acute emotions. Results revealed no differences between the groups in psychological factors (all P > .646, all effect sizes d < .015). State sadness was higher for patients with suspect CMD (16%) versus the other groups (P = .029). The groups did not differ in the association of psychological factors or emotions with anginal complaints (all P values > .448). CONCLUSION: Suspect CMD was not associated with more negative psychological factors compared to other groups. State sadness was significantly higher for patients with suspect CMD, whereas no differences in state anxiety and other psychological factors were found.

BACKGROUND: Negative emotions have been linked to ischemic heart disease, but existing research typically involves self-report methods and little is known about non-verbal facial emotion expression. The role of ischemia and anginal symptoms in emotion expression was examined. METHODS: Patients undergoing cardiac stress testing (CST) using bicycle exercise or adenosine with myocardial perfusion imaging were included (N = 256, mean age 66.8 ± 8.7 year., 43% women). Video images and emotion expression (sadness, anxiety, anger, and happiness) were analyzed at baseline, initial CST , maximal CST, recovery. Nuclear images were evaluated using SPECT. RESULTS: Ischemia (N = 89; 35%) was associated with higher levels of sadness (p = .017, d = 0.34) and lower happiness (p = .015, d = 0.30). During recovery, patients with both ischemia and anginal symptoms had the highest sadness expression (F (3,254) = 3.67, p = .013, eta2 = 0.042) and the lowest happiness expression (F (3, 254) = 4.19, p = .006, eta2 = .048). CONCLUSION: Sadness and reduced happiness were more common in patients with ischemia. Also, anginal symptoms were associated with more negative emotions.

BACKGROUND: The prevalence of myocardial ischemia is associated with anxiety. State and trait anxiety are more common in younger women compared to men, and high anxiety levels could affect hemodynamic reactivity during cardiac stress testing. The aim is to examine whether anxiety plays a role in gender differences in patients ≤ 65 and > 65 years in hemodynamic reactivity and ischemia during cardiac stress testing. METHODS AND RESULTS: Included were 291 patients (66.8 ± 8.7 years, 45% women) with suspect ischemia undergoing myocardial perfusion single-photon emission computed tomography (MPI-SPECT). Primary outcomes were semi-quantitative summed difference score (SDS) and summed stress score (SSS), as continuous indicators of myocardial ischemia. Analyses were stratified by age. Trait anxiety was measured using a validated questionnaire (GAD-7) and state anxiety using facial expression analyses software. Overall, trait and state anxiety were not associated with the prevalence of ischemia (N = 107, 36%). A significant interaction was found between gender and trait anxiety in women ≤ 65 years for SDS (F(1,4) = 5.73, P = .019) and SSS (F(1,10) = 6.50, P = .012). This was not found for state anxiety. CONCLUSION: SDS and SSS were significantly higher in women younger than 65 years with high trait anxiety. This interaction was not found in men and women over 65 years.

BACKGROUND: Patients with non-obstructive coronary artery disease (NOCAD) continue to experience disabling symptoms. Positive affect (PA) has shown a cardioprotective potential. Type D personality has previously been shown to have a deleterious effect on adverse outcomes in diverse cardiac populations. Little is known about the predictive value of PA and Type D personality for long-term outcomes in NOCAD patients. The aim was to investigate the effect of PA and Type D personality on clinical outcomes. METHODS: 547 patients (mean age 61 years±9, 48% male) who underwent a coronary angiography or CT-scan between January 2009 and February 2013 answered questionnaires concerning PA (GMS) and Type D personality (DS14). Cox proportional hazards analyses were performed. RESULTS: When analyzed dichotomously, PA was a significant predictor of need for repeat cardiac testing (HR=0.64, 95% CI: 0.41-0.99), but not emergency department (ED) admissions (HR=0.83, 95% CI: 0.52-1.32) after adjustment for age, sex, education, diagnosis by group, BMI and hypertension. Analyzed continuously, the predictive value of PA was non-significant for both repeat testing (HR=0.85, 95% CI: 0.69-1.06) and ED admissions (HR=0.98, 95% CI: 0.77-1.23). Type D personality, both continuously and dichotomously, was not significantly associated with the outcomes. Findings were also examined for men and women separately. CONCLUSION: Although Type D personality was not predictive of adverse events in this sample, PA is an interesting and important variable to take into account in NOCAD patients. Research on psychosocial factors in NOCAD patients should consider the importance of choices of endpoint, given the heterogeneity of NOCAD patients.
