Characterization of Left Ventricular Diastolic Function in Hypertension by Use of Doppler Tissue Imaging and Color M-Mode Techniques
The current study examined how pulsed wave Doppler (PWD), Doppler tissue imaging (DTI) and color M-mode (CMM) indices were used clinically to ascertain left ventricular (LV) diastolic dysfunction for individuals with hypertension (HTN). Participants were 278 patients placed in one of the following groups: healthy controls, HTN without LV hypertrophy (LVH), or HTN with LVH. PWD, DTI, and CMM were used to measure diastolic functioning for all participants with comparisons than made between groups.
- Statistically significant differences between groups on LV relaxation and filling pressures were found only when DTI methods were used.
- CMM-indices did not identify significant differences between groups of patients.
- Increased LV filling pressures might be an indicator of dysfunction leading to hypertensive heart disease.
- DTI methods were effective in evaluating LV relaxation and filling pressure as related to HTN.
