Do social isolation and loneliness increase the risk of myocardial infarction, stroke, and mortality?
While social isolation and loneliness are associated with an increased risk of cardiovascular events and mortality, this association is largely driven by conventional risk factors.
Isolated and lonely persons are at increased risk of AMI and stroke, and, among those with a history of AMI or stroke, increased risk of death. Most of this risk was explained by conventional risk factors.
Hakulinen et al. (2018) studied this question.
