A recent study has found that statin use could significantly decrease the risk of stroke and transient ischemic attack (TIA) among patients with atrial fibrillation (AF).
Presented at the annual meeting of the European Heart Rhythm Association in Barcelona, Spain, this research provides a new insight into the potential benefits of statin therapy in managing AF-related outcomes.
The research, led by Jiayi Huang from the University of Hong Kong, evaluated the association between statin use and AF-related outcomes in AF patients.
The team analyzed data from 51,472 patients newly diagnosed with AF between 2010 and 2018.
These patients were divided into two groups based on statin therapy use: 11,866 individuals using statins and 39,606 individuals not using statins.
During a median follow-up period of 5.1 years, the researchers found that previous statin use was significantly associated with a lower risk for ischemic stroke (IS) or systemic embolism (SE), compared to nonuse.
Similar trends were observed for the associations between previous statin use and hemorrhagic stroke (HS; SHR, 0.93) and TIA (SHR, 0.85).
Notably, long-term statin use of six or more years was found to predict a lower risk for IS/SE, HS, and TIA versus short-term statin use (three months to less than two years).
The stratified analyses consistently associated a lower risk for IS with statin use.
“These data support the use of statins to prevent stroke and transient ischemic attack in patients with new-onset atrial fibrillation,” stated Huang.
The findings hold substantial clinical implications, particularly considering that in AF patients, ischemic strokes are often fatal or disabling and pose a high risk of recurrence.
The Role of Statins
Statins are drugs that can lower cholesterol in the blood by reducing the production of cholesterol by the liver.
High levels of cholesterol can lead to the formation of plaques in the arteries, which can cause events like heart attacks and strokes.
Therefore, statins are often prescribed to individuals at high risk of these cardiovascular events.
In conclusion, this study provides compelling evidence for the potential benefits of statin use in AF patients, particularly regarding the prevention of stroke and TIA.
However, as with any medication, the decision to initiate statin therapy should be made on an individual basis, considering the patient’s overall health status, potential side effects, and the presence of other risk factors.
Further research is needed to validate these findings and to explore the mechanisms by which statins could exert these protective effects in AF patients.
