Insights
Direct oral anticoagulants (DOACs) are effective and safe for elderly atrial fibrillation patients. These anticoagulants offer a good alternative to older therapies, showing high compliance and efficacy in real-world use.
Area of Science:
- Cardiology
- Pharmacology
- Geriatrics
Background:
- Four direct oral anticoagulants (DOACs) are approved for atrial fibrillation (AF) treatment.
- Clinical trials demonstrate DOAC efficacy and safety, but real-world data in elderly populations is limited.
Purpose of the Study:
- To assess the effectiveness and safety of DOACs in patients aged 75 years and older with AF.
- To evaluate the impact of switching from previous anticoagulation treatments to DOACs in this demographic.
Main Methods:
- A prospective study included consecutive patients aged 75 years and older with AF who were switched to DOACs.
- Follow-up assessments were conducted at 3, 6, and 12 months via phone and in-person visits.
Main Results:
- 143 elderly patients (mean age 81 years) were switched to DOACs, with a median follow-up of 9.6 months.
- Four minor bleedings and one nonmajor bleeding event occurred, managed by dose adjustment or temporary cessation.
- Two strokes were reported in patients on dabigatran 110 mg, with no serious sequelae; 2.8% experienced adverse effects like nausea.
- Four deaths occurred, unrelated to anticoagulation therapy.
Conclusions:
- DOACs represent a viable and effective alternative to traditional anticoagulants for elderly patients with AF.
- High patient compliance and a favorable safety/efficacy profile position DOACs as a preferred option for long-term anticoagulation in older adults.
Background:
Four direct oral anticoagulants (DOACs) have been licensed for the treatment of atrial fibrillation (AF); efficacy and safety have been shown in clinical trials, but its real use in elderly and very elderly people is still unclear.
Aim:
To evaluate the impact of DOACs in our patients (pts) aged ≥75 years and switched from other treatments.
Methods:
From September 2013 to May 2015, all consecutive pts aged ≥75 years, males and females, in treatment for AF and switched to DOACs are considered in this study. Follow-up (FU) was scheduled after 3 and 6 months by phone and after 12 months by visit.
Results:
Two hundred thirty-two pts in treatment for AF were switched to DOACs, among these 143 (61.6%) pts aged ≥75 years (mean age, 81 years). The medium FU was 9.6 months, during which 4 minor bleedings in 4 different pts and 1 clinically relevant nonmajor bleeding were reported, all treated with temporary cessation or reduction in DOACs. Two strokes occurred in pts in treatment with dabigatran 110 mg, both resolved without serious sequelae; 2.8% of pts had nausea, itching, vomiting, or discomfort, half of these returned to acenocumarol, and the remaining switched to other DOAC. Four pts died, but the deaths were not related to anticoagulation.
Conclusion:
As reported for general people, also in our elderly population, DOACs resulted in a good alternative to old antithrombotic therapies. Efficacy and safety associated with a higher compliance by pts bring these drugs to be the first choice for long-term anticoagulation.
