Right ventricular function has important prognostic and therapeutic implications especially in heart failure. Right ventricular performance defines the prognosis in patients with heart failure but the assessment still has challenge because of its complex geometry and the interrelationship with the left ventricle. Right Ventricle Outflow Tract Fractional Shortening (RVOT FS) is a new parameter echocardiography, simple and easy to evaluate right ventricular function in patients with heart failure. Methods: This is a cross sectional study of 84 patients heart failure who has ejection fraction < 50% and undergo routine echocardiography in Haji Adam Malik Hospital since August 2018 until October 2018. RVOT FS was measured by M-mode from parasternal short-axis view at aortic valve level with magnified images of RVOT, and the cursor was aligned perpendicular to the anterior RVOT wall. Then, we measured RVOT end-diastolic (RVOT ED) and RVOT end-systolic (RVOT ES) diameters. Results: The cut-off value of RVOT FS <25.5 was 88.4% sensitive and 82.9% specific to identify patients with impaired RV function in patients with heart failure. There was positive correlation between RVOT FS, TAPSE and S’ with RV FAC. TAPSE has strongest correlation with RV FAC (r= 0.788, P<0.001), S’ also showed positive correlation with RV FAC (r= 0.703, P< 0.001) and RVOT FS (r= 0.644, P<0.001).Conclusion : The results of this study show that the values of RVOT FS can be used as a new parameter echocardiography for assessment right ventricular function in patients with systolic heart failure.

This study aims to examine whether QT dispersion can be used as a predictor of the severity of lesions in STEMI patients in Haji Adam Malik General Hospital. Methods: A total of 68 patients with STEMI who undergo coronary angiography at Haji Adam Malik General Hospital since Januari 2018 until December 2018 were recruited in this cross sectional study. QT dispersion was counted from the first ECG when patient admitted at the emergency room. And then coronary angiography was done, and the Gensini score was calculated as a parameter of coronary lesion severity.Results: In the ROC curve analysis, the cut-off value of QT dispersion in the prediction of severe coronary lesion was 80.5 (AUC 0.874, 95% CI 0.778-0.970, p<0.001). The STEMI group with QT dispersion ≥ 80.5 had a higher incidence of severe coronary lesion than the group with QT dispersion < 80.5 of 34 people (89.5%) versus 4 people (10.5%). QT dispersion ≥ 80.5 is considered to predict the severity of coronary lesion with a sensitivity of 89.5%, a specificity of 83.3%, a negative predictive value (NPV) of 86.2% and a positive predictive value (PPV) of 87.1%.

However, this paper emphasized on the study of various pharmaceutical impurities of anti-ulcer drug. The drug used for the study was omeprazole which is chemically known as (5-methoxy-2-[[(4-metboxy-3,5dimethylpyridinyl) methyl] sulfinyl]-l-benzimidazole) that inhibits gastric ATPase enzyme by oxidizingits sulfhydryl groups.The process involved during synthesis. The novel process come into existence due to incomplete oxidation of pyrmetazole and overoxidation to sulfone that leads to the formation of sulfone N-oxide. The procedure involved 5-methoxy thiobenzimidazole to the formation of an ester followed by coupling of the ester with the Grignard reagent of 2-chloromethyl-4-methoxy-3,5-dimethyl-pyridine. The novel synthesis process for pharmaceutical impurities achieve the expected yield and process observed to be short, simple. The synthesized impurity of proton pump inhibitors can be used as standard impurity, that can be utilized for further studied in various aspects.
