Aortic stenosis (AS) patients face higher risks of heart issues. Early diagnosis and timely aortic valve replacement (AVR) are crucial for managing severe AS and preventing complications.
Area of Science:
- Cardiology
- Vascular Medicine
Background:
- Aortic stenosis (AS) is linked to increased coronary risk factors and atherosclerotic disease.
- Statins may potentially slow AS progression.
- Classic severe AS symptoms include angina, syncope, and heart failure.
Purpose of the Study:
- To outline the diagnosis and management of aortic stenosis.
- To detail treatment strategies based on AS severity and patient factors.
Main Methods:
- Physical examination findings, including murmur characteristics, aid in differentiating AS severity.
- Doppler echocardiography is the primary diagnostic tool for AS presence and severity assessment.
Main Results:
- Severe AS necessitates aortic valve replacement (AVR) once symptoms manifest.
- Anticoagulation post-AVR depends on valve type and patient risk factors.
Conclusions:
- Warfarin is indicated for mechanical valves or bioprosthetic valves with specific risk factors (atrial fibrillation, thromboembolism, LV dysfunction, hypercoagulable state).
- Aspirin (75-100 mg daily) is recommended for bioprosthetic valves without these risk factors.
