Which triad of symptoms typically presents in a patient with aortic stenosis?

In cases of aortic stenosis, patients most commonly present with a triad of symptoms characterized by exertional dyspnea, angina, and syncope.

Exertional dyspnea occurs due to the left ventricle struggling to pump blood effectively against the narrowed aortic valve, particularly during activities that require increased cardiac output. This reduced stroke volume and subsequent heart failure manifests as difficulty in breathing during exertion.

Angina, or chest pain, arises from the imbalance between myocardial oxygen supply and demand, as the left ventricle must work harder to eject blood through the stenotic valve. This increased workload can lead to ischemia, especially during physical activity, where the heart's need for oxygen is greater.

Lastly, syncope, or fainting, can occur due to impaired cerebral perfusion from reduced cardiac output, particularly during exertion when the heart's ability to compensate is tested. When the patient exerts themselves, the combination of increased demand and compromised cardiac output may lead to a transient loss of consciousness.

This triad of symptoms is classically associated with aortic stenosis and is critical for diagnosis and management of the condition. Other symptom sets mentioned in the other options relate to different clinical scenarios and are not characteristic of
