Serum cholesterol levels in patients with panic disorders: a comparison with major depression and schizophrenia.

Results of several long-term follow-up studies suggest that mortality due to cardiovascular diseases is high in males with panic disorder (PD). Based on these data, various studies have been undertaken to determine the relationship between PD and total cholesterol (TC) levels; however the results obtained so far have not been consistent. We compared TC levels in 46 PD patients to those in 46 sex, age, smoking and alcohol consumption matched patients with major depression and 46 matched patients with schizophrenia. The relationship between TC and the severity of PD was investigated, and before- and after-treatment TC change was compared. TC levels were significantly higher in the PD group than in the other groups, regardless of sex. The severity of PD was not correlated with TC levels. TC levels did not decrease in remitted PD patients. These findings suggest that relatively high TC levels in PD patients are attributable to endogenous disease-specific factors. Clinicians should pay close attention to the correlation between high mortality due to cardiovascular diseases and relatively high TC levels in male PD patients.
