Examining Psychological Factors in Peripheral Artery Disease: Affective Temperament, Anxiety, and Depression in Patients Undergoing Revascularization Procedures.

Purpose: This study aimed to assess the prevalence of depressive and anxiety symptoms in peripheral artery disease (PAD) patients, correlating these symptoms with clinical parameters and examining affective temperaments within the study group.

Material And Methods: A total of 159 PAD patients, predominantly male, admitted for vascular surgery due to lower limb atherosclerosis, participated in this cross-sectional study. Various assessments were conducted, including the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A) for affective temperaments, the Hospital Anxiety and Depression Scale (HADS) for anxiety and depression symptoms, and the Numerical Rating Scale (NRS) for pain intensity.

Cognitive impairment is a common disease. Many studies attempt to explain the mechanisms of these dysfunctions formation, including correlations between cognitive functions and biochemical parameters. Scientists search for substances that would be indicators of cognitive functions and which could be determined in the cerebrospinal fluid or blood of the subjects.
