Central to the mission of the MBMC is to promote healthy lifestyles and reduce the overall burden of chronic disease within the community. It is therefore critical for our research to be accessible to the general public.

Positive and Negative Affect Is Related to Experiencing Chest Pain During Exercise-Induced Myocardial IschemiaMay 25, 2017
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.
