Silent myocardial ischemia is thought to be associated with worse cardiovascular outcomes due to a lack of perception of pain cues that initiate treatment seeking. Negative and positive affect (NA and PA) have been associated with increased/decreased pain reporting, respectively but these psychological factors have not been examined within the context of myocardial ischemia. This study evaluated the associations between PA, NA, and chest pain reporting in patients with and without ischemia during exercise testing. Results suggest that high levels of PA as well as NA may increase the experience and/or reporting of chest pain.

Panic disorder (PD) is common among asthmatics and is associated with worse asthma outcomes. This may occur due to psychophysiological factors or to cognitive/affective factors. This study evaluated the impact of panic attacks (PAs) on bronchoconstriction and subjective distress in asthmatics with and without PD. Results, presented as hypothesis generating, suggest that asthmatics with PD/PA exhibit increased panic-like anxiety, breathlessness and a respiratory pattern consistent with hyperventilation that was not linked to statistically significant drops in bronchoconstriction.

Women diagnosed with coronary artery disease (CAD) typically experience worse outcomes relative to men, possibly through diagnosis and treatment delays. This may be influenced by mood and anxiety disorders, which are more prevalent in women and have symptoms (eg, palpitations and fatigue) that may be confounded with CAD. Our study concluded that women with anxiety and no CAD history had higher rates of ischemia than women without anxiety, suggesting that anxiety symptoms might mask CAD symptoms and contribute to referral and diagnostic delays.

Nonadherence to clinical practice guidelines is referred to as clinical inertia. We review evidence for the ubiquity of clinical inertia across a variety of chronic health conditions, and the the organizational, system, patient, and provider factors that serve to maintain it. An evidence-based framework to address these limitations is proposed that uses behavior change theory and advocates for shared decision making and enhanced guideline development and dissemination.

COPD is highly prevalent and associated with substantial morbidity and mortality. Many studies have evaluated the prevalence of neuropsychiatric conditions in patients with COPD. This review presents evidence regarding the prevalence of neuropsychiatric conditions in COPD, their risk factors, and their impact on relevant outcomes. It also discusses assessment and treatment of neuropsychiatric conditions and makes recommendations for improved screening and treatment.

High rates (34%) of psychiatric disorders in patients evaluated for occupational asthma have been reported. This study concludes that psychiatric morbidity is associated with lower employment rates and greater use of emergency services. Greater efforts should be made to assess and treat psychiatric disorders in this population.

The vasovagal response (VVR) is a common medical problem, complicating and deterring people from various procedures. VVR involves processes similar to those observed during episodes of strong emotions and pain. We hypothesized that heightened perceived control would reduce symptoms of VVR.
