Abstract

Aim: Assessment of left ventricular diastolic function by transmitral doppler and Left atrial volume estimation.
Materials and Method: This perspective cross sectional study was conducted at AVBRH, JNMC, Sawangi, Wardha, which is an 850 Bedded hospital with facilities for tertiary care. The study was carried out in 200 patients (100 cases and 100 controls) Study Group comprised of patients with risk factors like diabetes mellitus, hypertension and ischemic heart disease. Control group were devoid of any risk factors.
Results: In our study we found that mean e/a ratio in the study group was 0.93 ± 0.13 while that in the control group is 1.14 ± 0.11. The difference was statistically significant. (p = 0.0001), Mean e wave deceleration time (DT) in the study group was 150.26 ± 13.88 while that in the control group is 138.71± 13.79 and the difference between these two groups was statistically significant. (p = 0.000), and Mean isovolumetric relaxation time (IVRT) in the study group was 95.44 ± 9.74 while that in the control group is 86.50 ± 8.90 and the difference between these two groups was statistically significant. ( p = 0.000), Mean left atrial (LA) volume in the study group was 29.38 ± 2.34 while that in the control group was 26.01 ± 1.41 and the difference between these two groups was statistically significant.
Conclusion: The study of transmitral Doppler and 2 D echo variables revealed that, e/a ratio, e wave DT, IVRT, LA volume demonstrated significant change towards abnormal in subjects with presence of risk factors i.e. HT, DM, IHD either single or multiple. As regards the two modalities (Transmitral doppler and 2 D Echo) it was observed that both are equally effective in detecting LV diastolic function abnormalities.
