The Hospital de Sant Pau has collaborated in a study of the “Health Bus” project which concludes that 71.4% of middle-aged people, between 45 and 70 years old, in Lleida with a low or medium cardiovascular risk present atheromatous arteries, i.e. fatty plaques. Of these, 20% have generalised atheromatous disease, with more than 3 atheroma plaques. This finding reaffirms the assumptions about the prevalence of subclinical, undiagnosed disease in the population with common risk factors such as occult kidney disease or diabetes.
