consuming and limited in poor acoustic window. In our study, weproposed a new LVEF estimation method, which predicts the decreasedleft ventricular ejection fraction. The rational of the studywas based on thefact that LVEF is correlated positively with lateral mitral annular planeexcursion (MAPSE) and inversely with diastolic left ventricular internaldiameter (LVIDd).

Methods: One hundred consecutive patients with good acousticwindow were included in the study. All underwent routine transthoracicechocardiography and MAPSE measurement. LVIDd/MAPSE wascalculated and compared with LVEF Simpson method by using ROCanalysis, with cut off-values of 30%, 40% and 50%.

Results: MAPSE and LVIDd could be measured in all patients. Themean age of patients was 59�17 years (65 men). Average LVEF valuesmeasured by Simpson method was 53%�15%. Of LVIDd/MAPSEratios, the cut off value of 5.0 predicted LVEF<30% with 89% sensi-tivity, 82% specificity, AUC:0,89, p<0,001; the cut off value of 4,0predicted LVEF<40% with 89% sensitivity, 83% specificity, AUC:0,936, p<0,001; cut off value of 3,5 predicted LVEF<%50 with 91%sensitivity, 90% specificity, AUC: 0,962, p<0,001.

Conclusion: Our new method, in which LVIDd is used as theindex of circular contraction and MAPSE is used as the index oflongitudinal contraction, is a useful method of predicting LVEFsemiquantitatively.

Objective: Chronic obstructive pulmonary disease (COPD) has beenassociated with a high frequency of atrial arrhythmias. Atrial conductiontime (ACT) has been proposed as a marker of atrial remodelling. Theaim of the present study was to evaluate atrial conduction featuresmeasured by tissue Dopper echocardiography in COPD patient and itsrelationships with spirometric parameters.

Method: Forty patients (mean age: 54.8 �9.6 yr) with COPDwithout additional cardiac diseases and 30 healthy subjects wereenrolled into the study. ACT was measured by tissue Doppler echo-cardiography by evaluating atrial electromechanical delay betweenlateral mitral annulus, septal mitral annulus, and right ventriculartricuspid annulus. The correlation between ACT and spirometric pa-rameters were analyzed.

Result: Two groups had similar demographic findings. Pulmonaryfunctions were significantly lower in COPD group than the control groupas expected. According to the AEMD measurements from different sitesby TDI, tricuspit ACT was significantly longer in COPD patients,compared with controls (p:0,01) (Table 1). The strong inverse correlationwas observed between tricuspidACT and the percent of forced expiratoryvolume in one second (FEV1 %) ( r¼e 0.45; p<0.001) (Figure 1). Themoderate positive correlation was found between tricuspid ACT andmean pulmonary arterial pressure (PAP) (r¼þ0.37; p 0.001).

Conclusion: Our study revealed that tricuspid ACT was prolongedin COPD patients. FEV1(%) and PAP level are important factors of thisprolongation. These results may explain the increased incidance of atrialarrhythmias in this population. However, larger prospective long-termfollow-up studies are warranted to reach a precise definition.

Evaluation of Left Ventricular Functions with StrainEchocardiography in Polycystic Ovary Syndrome Patients.G. Aslan1, R.C. Aslan2, L.E. Sade1, U. Bal1, G. Onalan2,H.B. Zeyneloglu2, E. Kuscu2, H.

Polycystic ovary syndrome (PCOS) is characterized by several meta-bolic abnormalities that may lead to the development of insulin resis-tance, diabetes, atherosclerosis which are associated with chronicinflammatory process and oxidative stress. Due to these facts, PCOSpatients have more risk for cardiovascular disease. Accordingly ourstudy is planned in PCOS patients with no cardiovascular symptoms toinvestigate myocardial functions. We used echocardiographic quantifi-cation tools to detect subclinical changes in myocardial functions.Echocardiographic, hormonal and metabolic measurements were per-formed in 26 PCOS patients and 23 healthy volunteers. Eventually, nodifferences were found between two groups’ strain, strain rate andmyocardial velocity measurements.
