Insights
Antithrombotic therapy is crucial for preventing blood clots in patients with prosthetic heart valves. This review examines risks and benefits for mechanical and bioprosthetic valves, including special patient populations.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Pharmacology
Background:
- Prosthetic heart valve use has risen significantly over the last 30 years.
- Antithrombotic agents are essential for preventing thromboembolic events in patients with prosthetic heart valves.
- Understanding the nuances of antithrombotic therapy is vital for patient management.
Purpose of the Study:
- To analyze the risks associated with thromboembolic events in prosthetic heart valve patients.
- To evaluate the benefits and risks of antithrombotic therapy for mechanical and bioprosthetic heart valves.
- To review antithrombotic strategies in specific patient groups, including those with intracranial bleeding, pregnant women, and surgical patients.
Main Methods:
- Comprehensive literature review of studies on prosthetic heart valves and antithrombotic therapy.
- Analysis of risk factors for thromboembolic events.
- Synthesis of data on antithrombotic efficacy and safety in diverse patient populations.
Main Results:
- Antithrombotic therapy remains the cornerstone for preventing thromboembolic complications.
- Risk-benefit profiles of antithrombotic agents vary between mechanical and bioprosthetic valves.
- Special considerations are necessary for managing antithrombotic therapy in high-risk groups.
Conclusions:
- Antithrombotic therapy requires careful individualized management in patients with prosthetic heart valves.
- Further research is needed to optimize antithrombotic strategies in complex patient scenarios.
- This review provides a framework for clinical decision-making regarding antithrombotic use in prosthetic heart valve patients.
Abstract:
The use of prosthetic heart valves has increased over the past 3 decades. Antithrombotic agents remain the mainstay of therapy to prevent thromboembolic events caused by the presence of a prosthetic heart valve. We examine the risks of thromboembolic events as well as the risks and benefits of antithrombotic therapy in patients with mechanical and bioprosthetic heart valves. We also review the data regarding the use of antithrombotic therapy in special groups of patients, such as those with intracranial bleeding, pregnant women with prosthetic heart valves, and patients with prosthetic heart valves undergoing surgery.
