[Algometric approach in the diagnostic evaluation of chest pain].
OBJECTIVE
To contribute to a global clinical evaluation of the patients with chest pain, giving a quantitative analysis of the painful experience in the sensory, emotional, value and mixed component and searching significant differences among the different causes of the symptom.


METHODS
We have administered the "Questionario Italiano del Dolore" by De Benedictis et al. to 92 patients with chest pain, who were divided into 4 diagnostic groups (acute coronary syndrome, coronary artery disease, oesophagus-gastric disease and other) and compared for the quantitative-qualitative features of the associated pain.


RESULTS
PRIrcE (Global Value Component) resulted higher in the group "other" (A) compared to the patients with acute ischemic heart disease (CIA), with a statistically significant difference (test U-Mann-Whitney; p = 0.04). This group shows statistically significant differences in the emotional component (PRIrcA; p = 0.01) even compared to pain associated with oesophagus-gastric disease (G). In regard to PRIrcA, the difference between G group and the group of patients with chronic ischemic heart disease (CIC), as well as the "double" category, resulted markedly significant (p = 0.03 and p = 0.01 respectively). We extrapolated the "describers" chosen by at least 50% of patients in every category and obtained the semantics configuration of chest pain for every diagnosis.


CONCLUSIONS
PRIrcE resulted lower in CIA group. PRIrcE e PR-IrcA are more represented in CIC group. The same conclusion is valid in the differentiation of pain between CIA and G group and between CIA and A group (the most representative of chronic pain). We found higher values in emotional component compared to pain of new onset as pain becomes chronic.
