Should we screen for asymptomatic left ventricular dysfunction in glaucoma patients?

BACKGROUND

The aim of the study was to assess the frequency of asymptomatic left ventricular dysfunction in primary open-angle glaucoma patients.

PATIENTS AND

METHODS

Two-dimensional and pulsed Doppler echocardiography of transmitral flow was performed on 31 glaucoma patients and 27 controls.

RESULTS

No significant difference was found in early (E) and late (A) transmitral filling velocity, velocity time integral E wave (VTIE) and A wave (VTIA), left ventricular end-diastolic pressure, pulmonary capillary wedge pressure, left ventricular ejection fraction (EF) and fractional shortening (FS). A significant difference was found in ratio E/A (P=0.04) and ratio VTIA/VTIE (P=0.05), although all obtained values were within the 95% confidence limit for the corresponding age.

CONCLUSION

Our study tends to indicate the possibility of dysfunction of myocardial relaxation in glaucoma patients, which might be partially attributed to systemic vascular dysregulation.
