Evidence links panic disorder to cardiovascular disease |
|
and a greater than two- fold risk of hypertension, |
|
myocardial infarction and sudden death. Investigations of |
|
this association suggest that panickers have increased |
|
cardiac risk because of underlying autonomic |
|
dysregulation. Because previous studies of cardiovascular |
|
reactivity and heart rate variability have been |
|
inconclusive, these factors were re-examined in panickers |
|
and controls during physiological challenge in the |
|
laboratory and in panickers during naturalistic panic. |
|
Forty-nine patients meeting DSM-IV criteria for panic |
|
disorder and 24 non- clinical controls underwent |
|
orthostatic, Valsalva and CO2 challenge while heart rate, |
|
blood pressure, vagal tone, and anxiety symptoms and |
|
distress were recorded. Panickers then exposed themselves |
|
to panic-provoking situations in dally life during |
|
ambulatory monitoring of heart rate, blood pressure and |
|
heart rate variability. |
