The exact length of time a patient with aortic stenosis can live is related to the patient’s age, severity of the disease, the presence of related complications, and whether the patient is actively diagnosed and treated. If severe stenosis is already advanced and complicated by heart failure with symptoms such as chest tightness and dyspnea and no surgical treatment, 50% of patients may die within 2 years, and successful aortic valve replacement surgery can greatly reduce the mortality rate within 1 year. These figures are relative, but it can be concluded from them that the detection of aortic stenosis must be actively diagnosed and treated to prolong survival.
