Answer

Aortic stenosis usually has an asymptomatic latent period of 10-20 years. During this time, the LV outflow obstruction and the pressure load on the myocardium gradually increase. Symptoms develop gradually. Exertional dyspnea is the most common initial complaint, even in patients with normal LV systolic function, and it often relates to abnormal LV diastolic function. In addition, patients may develop exertional chest pain, effort dizziness or lightheadedness, easy fatigability, and progressive inability to exercise. Ultimately, patients experience one of the classic triad of chest pain, heart failure, and syncope. [1]
