3.Study on the left ventricular systolic- function in the patients with the old cardiac infarction by cardiac ultrasound
Journal of Practical Medicine 2001;394(2):3-6
A cross-sectional discriptive, compare and control study on the 125 patients with the old cardiac infarction and 55 healthy people was carriout in the Army Central Hospital No108 from 3/1995 to 3/1998. The age and sex between 2 groups were the same. The results have shown that the EF% calculated as improved simpson and the interval from point E of the anterior leaf of mitral valve to the left side of the ventricular connection Septal eirs were 2 parameters with the sensitivity and specificity higher than other parameters of ultrasound. The patients with the old cardiac infarction had significantly reduced the left ventricular systolic function. This reduction was corelated with the cardiac infarction. The most reduced the left ventricular systolic function found in the group of the cardiac infarction in the both anterior and posterior septal.

4.Primary evaluation for ventricular function in healthy adults using radio nuclide ventriculography (R.A)
Journal of Practical Medicine 2002;435(11):33-34
The study was conducted on 25 healthy subjects (15 males, 10 females) with age ranged from 15 - 60 years. None have heart disease that identified by physical examination, cardiogram and echocardiography. Method of R.A with SPECT and S.A.G.E - Cardiac software was used. Main measurements were emptying parameters, filling parameters and wall motion. Findings suggested that indices of EF, PFR and TPF were similar to that of other oversea studies. Indices of TES, PER, TPE, 1/3EF, 1/3ER, MFR, 1/3FF, 1/3FR were showed but could not compare with other authors because of data limitation in literature. Indices of REF and RRS of wall motion were lower than that of other studies.

6.Monitor the changes of left ventricular systolic function in management of septic shock patients
Journal of Medical Research 2005;33(1):68-72
Study on 2 subject groups: control group including 48 healthy persons and case group: 34 patients (20 male, 14 female) with septic shock, all of them treated at Bach Mai Hospital from January 2003 to November 2003, aged from 16 to 75 year old. Subjects in control group underwent clinical and Doppler ultrasound examinations, had medical records. In case group, patients underwent clinical and paraclinical examinations for diagnosis and treatment followed by regime of the department. Results: 15/34 septic shock patients have cured and discharged (44.1%), 19 patients died (55.9%). At the first stage of septic shock, cardiac output (CO) and cardiac index (CI) increased (CO=6.461.85L/min; CI=4.351.24L/min/m2) but ejection fraction decreased (EF=50.69.27%), with 13 patients had EF<50% (38.2%). Before treatment, the CO and EF of survival group were lower than the dead group. During treatment, end-diastolic left ventricular volume increased along with EF, and heart rate reduced gradually to normal in survival group. These changes weren’t observed in the dead group.

7.Evaluation of left ventricular function in 64 patients with hypertension by Doppler ultrasound
Journal of Vietnamese Medicine 2005;309(4):40-46
Study was performed in 64 patients with hypertension who were treated at Viet Tiep Hospital, Hai Phong city from 2001 to 2002. The control group consisted of 36 normal healthy persons. Results: in patients with hypertension, the LA, Dd, IVSd, LWPd, LVMl increased more highly than in the control group. However, the evaluated parameters of the left ventricular function such as EF%, FS%, T%, lVS, T% LWP, the distance of E-lVS and curve EF of the heart valve decreased more than the normal persons. Only 15.62% of patients with hypertension had the left ventricular function decreased (EF<55%). While 90.62% of those patients had left ventricular function disorders. Reduced elastic ability of left ventricular occurred in majority of patients with hypertension (93.75%). The type of “unnormal” disorder of diastolic function occurred in 2 patients (3.12%)

8.The relation between QT interval and left ventricular function in primary hypertension patient
Journal of Practical Medicine 2003;463(10):11-13
Study 58 high pressure patients at Central Army Hospital 108 and 38 healthy and old people. The result was: QT gap is QTd87+-42ms, Qtcmax 485+-51, QT cd96+-33ms and QTc 443+-25ms longer comparing with 40+-13ms, 452+-45ms, 66+-10ms, 410+-27ms of normal people. QTd, QTcd, QTc in these patients initially incur hyperthropy of left vertricle, diostole and systole disorder which is taking longer than high pressure patients do not incur hyperthropy of left vertricle, diostole and systole disorder. Inverse relations between QTc and E/A index and direct proportion between QTd, Qtc and LVM, LVMI indices

Apical muscular ventricular septal defects (VSDs) are relatively rare conditions among all the different types of VSDs. Apical VSDs are difficult to treat because of they are difficult to visualize through a trans-atrioventricular approach, and especially in infants. Treatment by left ventriculotomy is associated with long-term ventricular dysfunction. Catheter-based intervention still shows less than satisfactory results and this type of intervention may not be possible in small infants. This report describes the benefits of right apical ventriculotomy in terms of successful closure of the lesion without harming the ventricular function.

10.Ventricular dyssynchrony in patients with permanent pacemaker.
Korean Journal of Medicine 2010;78(1):56-58
Physicians prefer traditional right ventricular apical pacing to right ventricular outflow tract pacing because of easy accessibility, short procedure time, stable lead function and a low incidence of complications. However, right ventricular apical pacing produce an abnormal pattern of ventricular activation compared with right ventricular outflow tract pacing. There is growing evidence that right apical pacing may have long-term detrimental effects on left ventricular function. The report of Kim et al. in this issue showed that ventricular dyssynchrony was commonly seen in patients with permanent pacemaker implantation. They suggested the role of paced QRS duration to predict ventricular dyssynchrony during the follow-up period in patients with permanent pacemaker. However, a large scaled prospective observational study is needed to assess the factors influencing ventricular dyssynchrony in Korean patients with permanent pacemaker.
