The Limitations of Social Behaviour Imposed by CoVid-19 Impacted the Perception and the Evolution of Peripheral Arterial Disease Negatively.

backgroundThe novel acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic imposed a national lockdown at the beginning of 2020. People faced social distancing, being forced to stay at home. Peripheral arterial disease (PAD) typically influences life habits and psycho-social relationship. It is now questionable how PAD can be affected by changes in lifestyle imposed by the Sars-CoV-19 Pandemic. This study's main objective is to evaluate how the limitations of social behavior set by Sars-CoV-19 Pandemic impact the perception and evolution of the disease in a group of patients with a diagnosed PAD.

methodsThe changes in the in the perception and the evolution of the PAD were evaluated by comparing results of a modified VascuQol-6 quality of life (QoL) survey referring to the time frame defined "No-Sars-CoV-2 period" (from July to December 2019) with results referring to the time frame defined "Sars-CoV-2 period" (from January to June 2020). An overall score (range 4-60) was calculated, and a comparison between the two period studies was reported. Receiver Operating Characteristics (ROC) Curves evaluated a delta value for each patient with revascularization of lower limb peripheral arteries. Optimal cut-offs were chosen based on their specificity, sensitivity.

resultsOne-hundred-two PAD patients gave their informed consent to take part in the study. A significant general worsening of patients PAD perception in the Sars-CoV-2 period was recorded for the following items: lower limbs health status perception; overall activity limitation; walking ability limitation; overall daily walking distance; lower limbs fatigue perception; concerns about PAD worsening; pain discomfort (P < 0.05). The pain intensity changed from 4.7 ± 2.9 in the No-Sars-CoV-2 period to 6.3 ± 2.9 in the Sars-CoV-2 period significantly (P < 0.0001), even though analgesic drug intake did not increase considerably in Sars-CoV-2 period (P = 0.15). The overall score was 20.3 ± 7.4 for the No-Sars-CoV-2 period and 27.4 ± 7.6 in the Sars-CoV-2 period (P = 0.0001). The ROC curve built to analyze the relation between Delta-score and the need for revascularization identifies a cut-off > 8.5 (Area Under the Curve 0.5436; CI 95% 0.4252 to 0.6620) with a sensitivity and specificity respectively of 52.6% (CI 95% 37.26-67.52%) and 65.6% (CI 95% 53.40-76.08%).

conclusionsPatients with PAD were significantly hit by all the restrictions and the social limitations imposed to reduce the Sars-CoV-19 virus diffusion. Our study confirms that the perception and the evolution of PAD were significantly affected during the "Sars-CoV-2 period".
