Background: Clinical classification of patients with acute coronary syndrome is essential step in identifying severe cases before referring them, fairly quickly, for the ultimate investigation of coronary angiography .Hence it is important to find out the extent at which the severity of the disease, based on clinical classification, agrees with its severity at angiography and to see whether traditional Risk factors or pas ischaemia played a role.
Patients and Methods : The angiographer data of 178 consecutive pts with Acute Coronary Syndrome (ACS) were retrospectively analyzed. The pts consisted of 114 with Unstable Angina (UA) and 64 pts with Non-ST-Segment Elevation Myocardial Infarction (NSTEMI). Patients were classified depending upon the predominating clinical assessment during hospitalization into four groups of progressively worsening ischaemia. They were; group 1; New onset Angina; 27 pts, group 2; Deteriorating Chronic Angina, 33 pts, group 3; Rest Angina 54 pts, and, group 4; Non-ST-Elevation Myocardial Infarction (NSTEMI), 64 pts.
Results : Coronary Angiography revealed that the frequency of multi-vessel coronary Disease (MVD) in group 1, 2, 3, and 4 were 48%, 73%, 72%, and 56% respectively which meant that worsening of ischaemia was not accompanied by commiserate increase of the frequency of MVD in Rest angina and NSTEMI. To explain that we calculated the average number of Five traditional Risk Factors; Hyperlipidaemia (HL), Diabetes Mellitus (DM), Hypertension (HTN), Smoking (SM), and Positive Received March 2006 Family History (PFH) in the four groups ofACS (R.F. score) and they were 1.72, 1.87, 2.13, 2.51 in Accepted May 2006 groups 1,2,3, and 4 respectively. Then we studied the relation of having one, two, three, and four orfive Risk Factors and the frequencies of Multi-vessel disease and they were; 43%, 67%, 76%, and 84% respectively which meant that the frequency of MVD ought to increase from group 1 to group 4 supporting the clinical classification. This prompted us to look into the individual Risk factors. The clinical data showed that the incidence of HL had risen
significantly in Ch. D. angina and Rest Angina (P: 0.03) and that the incidence of SM had risen significantly in NSTEMI (P.• 0.001). Since the angiographic data had demonstrated a significant association of HL with MVD and SM with SVD we may understand why the rate of MVD was not higher in NSTEMI than UA. To explain why the frequency of MVD in Rest Angina (g. 1) was not higher than Ch. D. Angina (g. 2) despite having worse ischaemia and higher R.F. Score we scrutinized the data and noticed that the main difference between group 1 and group 2 that chronic stable angina had preceded the onset of UA in Group 2 while it did not do in group 1. On the other hand Rest Angina and NSTEMI pis were a mixture of those with and without prior ischaemia. To follow this point further we divided both groups into two subgroups: one with history of prior ischaemia and one without it. The frequency
of MVD in Rest Angina and NSTEMI with prior ischaemia were 83%% and 81 %% compared to 54% and 39% respectively in pts without it.
Conclusion this study has shown that clinical classification in Acute Coronary Syndrome may predict severity of the underlying CAD to some extent however considering the no. Of risk factors and which Risk factor and whether there was antecedent ischaemia would improve the prediction a great deal.
Estimation of mechanical and physical rock properties is an essential issue in applications related to reservoir geomechanics. Carbonate rocks have complex depositional environments and digenetic processes which alter the rock mechanical properties to varying degrees even at a small distance. This study has been conducted on seventeen core plug samples that have been taken from different formations of carbonate reservoirs in the Fauqi oil field (Jeribe, Khasib, and Mishrif formations). While the rock mechanical and petrophysical properties have been measured in the laboratory including the unconfined compressive strength, Young's modulus, bulk density, porosity, compressional and shear -waves, well logs have been used to do a compar

Due to the different nature and behavior of the influencing parameters, more complex nonlinearity exists for Vp modeling purposes. In this study, a statistical relationship between compressional wave velocity and petrophysical parameters was developed from wireline log data for Jeribe formation in Fauqi oil field south Est Iraq, which is studied using single and multiple linear regressions. The model concentrated on predicting compressional wave velocity from petrophysical parameters and any pair of shear waves velocity, porosity, density, and

The assignment of suitable sites for water harvesting techniques is a promoted strategy to be introduced to the community, for handling the water scarcity and risk due to floods. In the eastern part of Missan, water is always hampered due to the limited availability during the drought, while floods frequently and intensely occur in the wet season. This study aimed to choose the potential and suitable sites for applied water harvesting system using remote sensing techniques and analytic hierarchy process (AHP). Ali Al-Garbi city is divided into three watersheds (site1, site2, and site3), which have been characterized by flash floods that produce high quantities of runoff.

El presente trabajo nace de una inquietud por la enseñanza del español en Irak a nivel universitario especialmente ante las dificultades que los alumnos árabes en general, e iraquíes en particular, encuentran en su proceso de aprendizaje. Nuestra primera inclinación fue, pues, prestar una atención directa y cercana al alumno como sujeto del aprendizaje, así como a lo que el alumno produce como resultado del mismo. En el presente trabajo pretendemos dotar al estudiante de los conocimientos lingüísticos necesarios para poder interaccionar en una variedad de situaciones y enfrentarse a problemas cotidianos, de manera que desarrolle las destrezas comunicativas que le permitan establecer una co
