In sedentary patients, even with severe stenosis, there may be no symptoms.

The classical symptoms are:

  • dyspnoea:
    • the raised filling pressure of the hypertrophied left ventricular raises the left atrial pressure and hence the pressure in the pulmonary vein
    • may occur late in the disease

  • angina of effort:
    • occurs when coronary blood flow is inadequate for the hypertrophied myocardium
    • it is rare for angina at rest to occur (unless there is coincidental coronary heart disease)

  • syncope or dizziness:
    • may occur with exertion due to a low cardiac output and peripheral vasodilatation
    • syncope not associated with exertion may be due to arrhythmias
