What is the prognosis for patients who develop symptoms like angina or syncope due to aortic stenosis?

Patients with aortic stenosis who experience symptoms like angina or syncope generally have a poor prognosis. When these symptoms develop, it is indicative that the condition has progressed significantly and the heart is under considerable strain. Most patients with symptomatic aortic stenosis have a shortened life expectancy; without intervention such as valve replacement, they face a high risk of mortality within 2 to 3 years. Symptoms suggest that the left ventricle is struggling to pump effectively due to the narrowed aortic valve, leading to increased pressures and potential heart failure.

Timely surgical interventions can improve outcomes, but the presence of symptoms signifies advanced disease and associated risks. Thus, recognizing the severity of the condition in the presence of these symptoms is crucial for proper patient management and discussing realistic expectations concerning prognosis.
