Risk factors for cardiovascular illness in panic disorder patients.

Supine and standing heart rate (HR) and blood pressure measures were compared among 19 nonsmoking normal controls, 29 smoking patients and 36 nonsmoking patients with panic disorder. The smoking patients had a significantly higher supine HR, standing diastolic blood pressure, standing mean blood pressure and supine and standing cardiac load measures compared to both patient nonsmokers and controls. There was no significant difference between controls and nonsmoking patients for any of the above measures except for the higher standing HR and the delta increase in HR upon standing in female panic disorder patients which suggests increased adrenergic activity. When lipid values of panic disorder patients (n = 92) were compared to National Reference Values for their sex and age for an increased risk of cardiovascular illness, there was no significant risk with regard to plasma levels of total cholesterol, high-density lipoprotein cholesterol or low-density lipoprotein cholesterol.
