To examine the association between anticholinergic burden and incident cardiovascular events, including specific types of CVDs, in a large general population cohort from Stockholm, Sweden.
Key Findings:
Higher anticholinergic burden was associated with an increased incidence of cardiovascular events, including specific types such as stroke and myocardial infarction.
Specific types of cardiovascular diseases showed varying degrees of association with anticholinergic medication load.
Cumulative exposure to anticholinergic drugs may disrupt cholinergic signaling, impacting cardiovascular regulation.
Interpretation:
The findings suggest that increased anticholinergic burden could be a risk factor for cardiovascular events, highlighting the need for careful medication management in older adults to mitigate risks.
Limitations:
The study's observational nature limits causal inferences.
Potential confounding factors may not have been fully accounted for, including unmeasured confounders.
Reliance on prescription data may not capture all anticholinergic exposures.
Conclusion:
Greater exposure to anticholinergic medications is linked to an elevated risk of cardiovascular events, warranting further investigation into the mechanisms and implications for clinical practice, particularly regarding specific types of CVD.
