The goal of this study was to evaluate the prevalence and clinical characteristics of mental stress-induced myocardial ischemia.
Mental stress-induced myocardial ischemia is prevalent and a risk factor for poor prognosis in patients with coronary heart disease, but past studies mainly studied patients with exercise-induced myocardial ischemia.
Eligible patients with clinically stable coronary heart disease, regardless of exercise stress testing status, underwent a battery of 3 mental stress tests followed by a treadmill test. Stress-induced ischemia, assessed by echocardiography and electrocardiography, was defined as: 1) development or worsening of regional wall motion abnormality; 2) left ventricular ejection fraction reduction ≥8%; and/or 3) horizontal or downsloping ST-segment depression ≥1 mm in 2 or more leads lasting for ≥3 consecutive beats during at least 1 mental test or during the exercise test.
Mental stress-induced ischemia occurred in 43.45%, whereas exercise-induced ischemia occurred in 33.79% (p = 0.002) of the study population (N = 310). Women (odds ratio [OR]: 1.88), patients who were not married (OR: 1.99), and patients who lived alone (OR: 2.24) were more likely to have mental stress-induced ischemia (all p < 0.05). Multivariate analysis showed that compared with married men or men living with someone, unmarried men (OR: 2.57) and married women (OR: 3.18), or living alone (male OR: 2.25 and female OR: 2.72, respectively) had higher risk for mental stress-induced ischemia (all p < 0.05).
Mental stress-induced ischemia is more common than exercise-induced ischemia in patients with clinically stable coronary heart disease. Women, unmarried men, and individuals living alone are at higher risk for mental stress-induced ischemia. (Responses of Myocardial Ischemia to Escitalopram Treatment [REMIT]; NCT00574847).
"It is well known that mental stress-induced ischemia is more common than exercise-induced ischemia in patients with clinically stable coronary heart disease. Women, unmarried men, and individuals living alone are at higher risk for mental stress-induced ischemia . Mental stress induces transient myocardial ischemia in one third to one half of patients with CAD. "
[Show abstract][Hide abstract] ABSTRACT: Introduction. Psychiatric problems and stresses may deteriorate the prognosis of patients with IHD. So evaluating their frequency possibly will promote our perspective regarding their vital importance in the field of consultation-liaison psychiatry. Method and Materials. One hundred and one (101) patients with IHD were interviewed in CCU of a general hospital by a psychiatrist to find whether there was any relationship between cardiac events and psychiatric problems or stresses. Results. Cardiac events were significantly more prevalent among patients with both psychiatric problems and biological risk factors (P < 0.05). Also, the number of patients suffering from psychiatric problems was significantly more than cases without that (P < 0.05). There was a significant difference between male and female patients regarding the type of stress (P < 0.01). 79% of total stresses were experienced by patients who had as well psychiatric problems (P < 0.0001). In addition, there was significantly more dysthymic disorder in the acute group of patients in comparison with major or minor depressive disorder in the chronic group (P < 0.001). Conclusion. The high prevalence of psychiatric problems and psychosocial stresses among patients with IHD deserves sufficient attention by clinicians for detection, monitoring, and management of them.

[Show abstract][Hide abstract] ABSTRACT: Scientific advances have led to substantial reductions in coronary heart disease (CHD) mortality over the past two decades. Impressive achievements in understanding sex differences in CHD outcomes are currently overshadowed by the limited exploration of the health disparities among young women with acute coronary syndromes (ACS). Even though patient-reported outcomes (PROs) such as perceived health and quality of life (QoL) independently predict cardiovascular events and mortality, there is a paucity of research on the determinants of PROs of young women. This review highlights the scientific evidence of the biological and psychosocial factors contributing to poor health and QoL among young women with ACS. Ascertaining the biopsychosocial determinants of PROs among young women will permit translation of this science into novel strategies for improved risk stratification and appropriate triage to age-specific and gender-sensitive personalized interventions that enhance self-management and reduce health differentials among this vulnerable cohort.
