Hearing loss affects 1 in 5 people worldwide, an increasingly common occurrence as populations around the world begin to age at a faster rate
A team from the Yong Loo Lin School of Medicine at the National University of Singapore (NUS Medicine) found that people with hearing loss had a 13% and 28% increased risk of all-cause and cardiovascular death, respectively, at from 26 observational studies. which had more than 1.2 million participants.
People with both hearing loss and vision loss have been found to have a 40% and 86% increased risk of all-cause and cardiovascular death, respectively.
Compared to vision loss and other long-term chronic conditions, hearing loss has not received as much priority and attention because it is more difficult for family members and patients themselves. themselves to detect the gradual and subtle decline of hearing. It is easy to make the connection that hearing loss increases the risk of death from traffic accidents and work accidents.
However, through their research, the NUS Medicine team found that cardiovascular deaths occurred at a faster rate in people with hearing loss, after taking into account age, gender, socio-economic status and lifestyle habits such as smoking and alcohol consumption, and chronic diseases such as high blood pressure, heart disease, cognitive impairment and stroke.
The possible explanation that people with hearing loss have a higher risk of cardiovascular death may be due to increased stress, anxiety and depression, which can worsen heart problems.
Another possible explanation is that hearing loss can also aggravate physical frailty, leading to decreased body reserves, in turn increasing vulnerability to external stressors that trigger cardiovascular death.
