Atherosclerosis knowledge - diagnosis and management in primary care

International audienceBackground - Atherosclerosis is the leading cause of death worldwide. Ischaemic stroke, coronary heart disease (CHD), and peripheral artery disease (PAD) are different forms of atherosclerotic disease. Knowledge among general practitioners (GPs) about the three main locations of atherosclerosis has never been conjointly explored in a single study. The aim of this survey was to compare GP awareness on the subject of these three different clinical presentations. Materials and methods - Between February 2017 and May 2017, a self-administered survey was emailed to 18,500 French GPs. The questionnaire comprised three clinical cases involving cases of transient ischaemic attack (TIA), stable angina (SA), and intermittent claudication (IC). Each case was explored with seven similar questions. The primary endpoint was the number of physicians who correctly answered five questions for each clinical case. Results - The survey was completed by 1,724 GPs. TIA knowledge (48.2 %) was significantly higher than the SA knowledge (3.0 %) and IC knowledge (0.4 %). We also found a significant difference between SA knowledge and IC knowledge. The percentages of GPs who correctly diagnosed TIA, SA or IC were 96.7, 89.7, and 96.5 %, respectively (p < 0.0001). Poor knowledge ratings for all three locations were observed for inadequate prescription of supplementary investigations and treatments. Conclusions - Our study demonstrates that GPs' knowledge about atherosclerosis disease varies significantly depending on disease location. GPs diagnose correctly but need to be backed up for their management of patients with atherosclerosis
