 In addition, some observational studies in elderly patients have suggested an association between frailty and cardiovascular disease: fragility and cardiovascular disease share a common biological pathway, and cardiovascular diseases may accelerate the onset of frailty. The frailty syndrome was identified in 25 to 50 of patients with cardiovascular disease, according to the rating scale used and the population studied. Frail patients with cardiovascular disease, in particular those undergoing invasive procedures or suffering from coronary artery disease and aortic valve disease, have a much higher adverse events and complications, suggesting the need for a more accurate functional stratification and a more careful evaluation of the riskbenefit ratio of some invasive procedures.
