Left ventricular diastolic dysfunction has been proposed as the basis of heart failure in patients with normal left ventricular systolic function. Doppler indices of mitral inflow have been widely used to diagnose this condition and have been shown to correlate well with increased left atrial pressure in patients with cardiovascular disease. We wanted to establish age-specific criteria for normality of these indices in a large population and to determine the association of abnormal values to age and cardiovascular disease.

Mitral flow derived Doppler indices of left ventricular diastolic function in a general population. The Tromsø study
