Health-related quality of life in patients with peripheral arterial disease undergoing percutaneous transluminal angioplasty: a prospective one-year follow-up.

Measuring Health Related Quality of Life has become more and more important in evaluating patients with peripheral arterial disease. This prospective longitudinal survey aimed to investigate health related quality of life over time in patients with peripheral arterial disease (PAD) undergoing percutaneous transluminal angioplasty (PTA) between December 2005 and June 2008. Health Related Quality of life was assessed using the Claudication Scale (CLAU-S) and EQ5D and the Sense of Coherence Scale was used to estimate the patients' sense of coherence. The findings of this study shows that the total CLAU-S score was improved both at one-month follow-up (p < 0.0001) and one-year follow-up (p < 0.0001) compared to baseline. There were significant differences regarding all five dimensions: every day life, pain, social life, illness-specific fears and psychological wellbeing. The EQ5D computed by index improved significantly both at one-month follow-up (p = 0.0006) and one-year follow-up (p = 0.0019) compared to baseline. Differences were found between the groups with low and moderate sense of coherence (p = 0.0169) as well as between the groups with low and high sense of coherence (p = 0.0208) regarding health related quality of life (HRQoL). This study showed that PTA improves HRQoL among individuals suffering from PAD and that the effect is sustainable over time. For more accurate results, a disease-specific instrument should be used to evaluate HRQoL.
