Back ground: Chronic total occlusion (CTO) of coronary arteries remains one of the most challenging lesion subsets in interventional cardiology even with the development of medical devices and operator expertise. Successful revascularization results in improved in angina status ,increased exercise capacity and reduces the need for lat CABG surgery .
Objectives: This study sought to determine the overall procedural success rate of percutaneous coronary intervention (PCI) for CTOs and to examine the relation between variables such as; patients’ characteristics, risk factors, lesion characteristics and procedural success rate.
Methods: In this study ,clinical and coronary angiography data of (80) patients with CTO who underwent PCI between May 2009 and May 2010 in Ibn Al-Baitar Hospital for cardiac surgery and Al-Nassryia cardiac center were prospectively analyzed . The clinical data were collected using the patients files and angiographic data by review of their films.
Results: There were (80) Patients with CTO ,They included 62 men (77.5%) and 18 women (22.5%) ,Age range 36-76 year with mean age 55±8.75 and male to female ratio was 3:1 .The procedural success rate of PCI was 66 patients (82.5%). All 23patients(100%) with lesionlength less than 15 mm had successful PCI compared to 43 out of 57 patients in whom the lesion was more than 15mm (75.4%) p value < 0.01. The procedure was successful in 54 patients out of 60 with tapered stump(90%) compared to 12 out of 20 patients with abrupt stump(60%) p value <0.005.In CTO lesion with angulations less than 45 degree ,the procedure was successful in 27 patients out of 28 (96.4%)compared to 39 out of 52 patients in whom the angulations was more than 45 degree 52(75%) p value<0.01. The most common cause of procedural un success was inability of guide wire crossing through the totally occluded segments which represented 11(78.5%), Inability to cross the lesion with a balloon in 2 patients(14.2%) and inability to dilate balloon in one patient (7.1%) P<0.001.
Conclusion: Percutaneous coronary intervention of chronic total occlusion is an effective therapeutic procedure with high success rate 82.5%. The length of chronic total occlusion ,degree of angulations and stump morphology are strong predictors of success procedure.

Coronary artery disease (CAD) is the leading cause of death worldwide. Certain genetic polymorphisms play an important role in this multifactorial disease, being linked with increased risk of early onset CAD.
To assess six genetic polymorphisms and clinical risk factors in relation to early onset nondiabetic Iraqi Arab CAD patients compared to controls.

Al-Rustamiyah plant is the oldest and biggest sewage treatment plant in Iraq; it locates in the south of Baghdad city. The plant suffers from serious problems associated with overflow and low capacity. The present work aims to upgrade the heart of biological treatment process through suggesting the use of membrane bioreactor; (MBR). In this work, fouling of membrane during sewage treatment has been analyzed experimentally and theoretically by fouling mechanisms. Aeration has been applied in order to control fouling through producing effective diameters of air bubbles close to the membrane walls. Effect of air flow rate on flux decline was investigated. Hermia's models were used to investigate the fouling mechanisms. The results showed th

The optimal combination of aluminum quality, sufficient strength, high stress to weight ratio and clean finish make it a good choice in driveshafts fabrication. This study has been devoted to experimentally investigate the effect of applying laser shock peening (LSP) on the fatigue performance for 6061-T6 aluminum alloy rotary shafts. Q-switched pulsed Nd:YAG laser was used with operating parameters of 500 mJ and 600 mJ pulse energies, 12 ns pulse duration and 10 Hz pulse repetition rate. The LSP is applied at the waist of the prepared samples for the cyclic fatigue test. The results show that applying 500 mJ pulse energy yields a noticeable effect on enhancing the fatigue strength by increasing the required number of cycles to fracture the

It is clear that correct application of antibiotic prophylaxis can reduce the incidence of infection resulting from the bacterial inoculation in a variety of clinical situations; it cannot prevent all infections any more than it can eliminate all established infections. Optimum antibiotic prophylaxis depends on: rational selection of the drug(s), adequate concentrations of the drug in the tissues that are at risk, and attention to timing of administration. Moreover, the risk of infection in some situations does not outweigh the risks which attend the administration of even the safest antibiotic drug. The aim of this study was to comp

Background: overweight and obesity are the fifth leadingrisk for global deaths. At least 2.8 million adults die eachyear as a result of being overweight or obese. Numerousstudies show that weight loss, even if only 5-10%,significantly improves dyslipidemia, hypertension, diabetesmellitus, risk for osteoarthritis and its symptoms and risk forselected cancers.Objectives: is to evaluate the effect of diet and exerciseprogram on anthropometric and biochemical status of adultobese patients.Methods: descriptive study. 124 adult obese patientsattending Al Kindy obesity research and therapy unit duringDecember 2012 were included.
