Background: The present study was designed to investigate the trend and determinant factors among cardiac disabled workers presented in the years 2003-2005 at Health Insurance Committee for disability rating in Alexandria and to compare the currently used system with others. Methods: A retrospective study was conducted to review complete records for those below the age 65 years. The available data were coded to include age, gender, job title, disabling symptoms, presence or absence of abnormal findings in resting electrocardiogram and chest X-ray. Extrainvestigations were considered by the committee in some cases including echocardiography, cardiac stress test and coronary angiography. Therapeutic interventions were coded and etiological diagnosis was classified into ischemic heart disease (IHD), rheumatic heart disease (RHD), hypertension (HT) and cardiomyopathies (CM). The functional diagnosis was reported as presence or absence of heart failure and disability was rated as partial or total. Results: The results revealed that rates of disabling dyspnoea, CM and heart failure were significantly increasing from year to year (p=0.038, 0.039 & 0.023 respectively). The most common etiological diagnosis for the presented cases was IHD with high rates ranging from 69.7% to 73.6% across the 3 years. Logistic regression with total disability as the dependent variable showed that heart failure and additional information by echocardiography were the independent determinants (p= 0.020 & 0.004 respectively). Simplified comparison between current cardiac disability rating system and American medical Association impairment classification was given. Conclusion: The present disability rating system lack standardization and quantification. It is recommended to integrate the metabolic equivalent (METs) measurement with the current system and to emphasize cardiovascular preventive programs to control cardiac disability. INTODUCTION: There is a global observation of increasing burden of cardiovascular diseases especially in developing countries. Although, cardiovascular mortality is still high, yet it witnessed some reduction due to preventive efforts and possibly due to improvement in management. However, the cardiovascular disability with its economic and social cost is increasing. (1) Cardiac disability rating is frequently

Optimum perforation location selection is an important task to improve well production, and hence the reservoir development process. This paper aims to detect the optimum perforation interval by determining the oil zone interval, petrophysical properties, and productivity ratio to check the efficiency of the perforating process. Drilling, geological and Well log data were used to achieve this study. Geological data such as the depth WOC and the contour map are used to make a 2D crosssectional of the WOC by using petrel 2009 software. It has been used to determine the well location in the structure, whether it was in the crust or the flank of structure. The drilling history data such as mud weigh, mud cake resistivity...etc. are used to make environmental correction for well logs device to obtain corrected borehole readings. The well logs data are inserted into Interactive Petrophysics software to make the environmental corrections, interpretations and determine the oil zone interval.
