Abstract: Coronary artery disease is one of important diseases as in many cases ends up with death. Among many types of coronary artery disease is the lipoprotein plaque deposition on the artery wall. Much research reports have been appeared in the literature concerning the causes, investigation, and treatment.Conventional angiography was very valuable procedure to investigate and assess the plaque in the walls of the coronary artery also the amount and position of occlusion.As the Computed Tomography scanners were developed a new noninvasive procedure was invented using the calcium present in the plaque as an indicator for the amount of plaques in the coronary artery. The procedure can also specify the position and the severity of the occlusion. The coronary artery assessment in the plaque is taken as calcium score which based on amount of calcium and plaque formation.In the present study we were aiming to investigate the validity of the calcium score in the diagnosis of coronary artery disease, and also to find the relation between calcium score with calcification and plaque formation.Sixty one patients were evaluated 40 male and 21 female who had symptoms chest pain to determine the prevalence and risk factor correlation of coronary artery calcification deposits as a marker of atherosclerosis.As History of hypertension, age, represents the characteristics of study. And Anthropometric measurements, weight in (kg), height (m), and body mass index (kg/m2). The level of lipid profile for fasting serum of normal and abnormal lipids were analyzed in (mmol/L) cholesterol, triglyceride, high density lipid, low density lipid, very low density lipid.Patients were advised to come fasting and before Computed Tomography Angiography examination.They have been given Beta blocker to reduce the heart rate to less than 60 beats/min. The patients were instructed to lie on the couch of CT scanner and stay relaxed. Contrast mediums were injected by means of injector in vein immediately before scanning.Results revel that not all patients show high calcium score in spite of chest pain on the other hand those patients with high calcium score they also have an increased plaque in their coronary artery .At low calcium score (0 - 100), Cholesterol, Triglyceride and High density lipoprotein are generally inversely proportional with calcium score with the exception of Low density lipoprotein remains virtually unchanged in the whole range of calcium score (0 > 300).While at high calcium score concentration > 300 these lipoproteins are directly proportional with calcium score in contrast with High density lipoprotein which is inversely proportional with calcium score.1 - Low or zero calcium score does not exclude definitely coronary artery disease in other word a person with low or zero may have a sever occlusion and needs further investigation.2 - The correlation between calcium score with High density lipoprotein, urea and creatinine is increased as the calcium score.3 - Its appears to be that the number of vessel involve calcium score different for different gender.

Abstract: الكثير من امراض القلب يمكن ان تؤدي الى تضخم في عضلة القلب, هذا التضخم ناجم عن زيادة الاجهاد على العضلة القلبية مثال ذلك : ضغط الدم الغيرمسيطر عليه لمدة طويلة, امراض صمامات القلب او التشوهات الولادية للقلب باللاضافه الى اسباب اخرى كثيرة, اما اذا استمر سبب الاجهاد لمدة طويلة سوف يسبب عجزفي القلب. في البحث الحالي حاولنا استقصاء التغيرات الحاصلة في عضلة القلب نتيجة التضخم وعجز القلب.تضمنت الدراسة (50 مريضا") و50(شخصا" صحي). تم اختيار المرضى فقط الذين تبين لديهم تضخم بالقلب مع عجز في القلب.كذلك تضمنت الدراسة قياسات عديده الى عوامل تشخيصية لعضلة القلب من خلال قياسات اخذت بجهاز صدى القلب((echocardography.اخذت القياسات بصورة رئيسئة للتغيرات التي اصابت حجم البطين الايسر ومن ثم تمت قياسات المتغيرات الاخرى او التي لها علاقة )بتضخم القلب و(LV Remodeling وهذه العوامل تتعلق بقصور عمل القلب الانقباضي والانبساطي. لقد تضمنت القياسات : - (LVIDd, LVIDs, E/A, IVRT, IVCT, ET, EF%, PWTd, IVSTd, VTI, LVOT, IMP, LVMI, SV, CO and RWT)اظهرت النتائج ان (9) لديهم (Concentric hypertrophy) و(37) لديهم (Eccentric hypertrophy)و (4) فقط كانت نتائجهم ضمن الطبيعي ((Normal geometry. حتى وصلت الى (4) وزيادة الحجم الانقباضي للبطين الايسر E/A تغيرات كثيرة اخرى شملت زيادة مبالغه ل مع نقصان في كمية ضخ الدم للجسم مع تغير في عرض الجدارالنسبي للبطين الايسرRWT)). الزيادة في التثخن في البطين الايسر (Concentric remodeling) يمكن ان يكون قد تسبب في كثرة الجهد على عضلة القلب بينما الجلطة القلبية والتليف الحاصل من جرائها قد يعطي (Eccentric hypertrophy) .كذلك اظهرت النتائج قلة في قيمة سرعه الدم خلال الصمام الاكليلي كذلك انقباض الاذين الايسر ( (Aربما تسببت عدم كفائة الاذين الايسر كذلك نقصان في قيمة (LVIDd/LVIDs) بسبب نقصان في تقلص LVIDs)) كذلك (RWT) وزيادة في ((LVMI هذا علاوة على عوامل كثيرة اخرى والتي تعطي تغيرات اقل وضوحا".ويمكن الاستنتاج الى ان الاجهاد المستمر لمدة طويلة من الممكن ان يولد التضخم, وبعد وقت اخر يولد عجز القلب. وهذا ممكن ان يؤثر على : - 1 - شكل وحجم القلب.2 - E F%.3 - CO. | Many cardiac diseases can cause cardiac hypertrophy developed by the established cardiac overload, such as long term of uncontrolled hypertension, valvuler disease or congenital anomaly and many more causes. If the cause of hypertrophy persists for long time it generates heart failure.In this work we have investigated the changes induced in the myocardium after hypertrophy and heart failure. An Important factor's is the changes in the size and dimension which allow us to study of the heart remodeling.Methods : The study included 50 normal individuals and 50 patients, only those patients who developed hypertrophy and failure were chosen.The study has included the measurements of many cardiac parameters through the echocardiography. the measurements were primarily taken for the changes in the left ventricle (LV) size and volume, then extended to many other parameters which are influenced by cardiac hypertrophy and remodeling, such as parameters linked with diastolic and systolic dysfunction.The measurements have included : Left ventricle internal diameter at diastole (LVIDd), Left ventricle internal diameter at systole ( LVIDs), Peak velocity of early transmitral ( E), Peak velocity of late transmitral flow (A), Isovolumetric contraction time (ICT), Isovolumetric relaxation time (IRT), Ejection time (ET), Ejection fraction (EF%), Cardiac output ( CO), Index of myocardial performance (IMP), Left ventricle mass index (LVMI ), Posterior wall thickness at diastole ( PWTd), Relative wall thickness ( RWT), Stroke volume (SV), Velocity time integral (VTI), Interventricular septum thickness at diastole (IVSTd) and Left ventricle outflow (LVOT).Results : Result have shown (nine percentage) of patients have centric hypertrophy (remodeling) and (thirty seven percentage) have eccentric hypertrophy and only four patients are similar to normal.Many changes were observed these are an exaggerated ratio of (E/A) goes up to (4), an increase in the (LV volume) dimension at systole for patients (85 %), a reduced cardiac output for patients and a relative wall thickness (RWT).Discussion : The change in the wall thickness such as increase in the LV wall thickness found incentric remodeling this is caused by overload while those with MI and myocardium fibrosis may show eccentric hypertrophy.Results have also show many changes in the echocardiography reduced value of A probably caused by inefficient LA contraction and reduced value of LVIDd/LVIDs also caused by the larger volume of LVIDs giving inefficient LV contraction for patients also a relative wall thickness (RWT)and an increase in the average LVMI (70.31%).Many other less significant changes. Conclusion : In conclusion long term cardiac overload can induce hypertrophy, after a period of time heart failure may ensue. This can influence 1 - the shape and size of the heart, 2. E F%, 3 . CO

Abstract: This study was conducted in pursuit of gaining a better understanding of the importance of hypothermia for cardiac surgery, and for CABG in particular. Most of the cardiac surgeons worldwide are accustomed to the use of mild hypothermia (32 - 35)°C for CABG procedures. Studies showed however that the risks of exposing the patient to mild hypothermia are similar to the risks endured during moderate hypothermia (28 - 32)°C. Objectives This study sought to weigh the benefits of mild hypothermia and moderate hypothermia against that of normothermia (35 - 37)°C concerning their impact on tissue oxygen consumption. Design This study is Prospective, randomized, comparative and purely observational and does not involve any intervention to the patient beyond the standard normal management. Setting At the department of physiology, college of medicine, Al - Mustansiriyah university in cooperation with the Iraqi Center for Heart Diseases and Ibn Al - Bitar Specialized Cardiac Surgery Center, in Baghdad, between December 2014 and April 2015. Patients, materials and methods Seventy patients, (55) males and (15) females, undergoing coronary artery bypass grafting surgery (CABG) were included in this study. Patients were allocated into three groups according to the surgeon's preferences; viz (normothermia, mild hypothermia and moderate hypothermia). Systemic complications associated with hypothermia were investigated via chemical analysis of the blood samples for renal and liver functions. Blood samples were collected two times during CPB from the arterial and venous ports of the oxygenator and were immediately analyzed to determine oxygen consumption and oxygen delivery. Results The decrease in the temperature for the hypothermic groups showed similar values of oxygen delivery (DO2) to that of normothermia (3537)°C at the same period during CPB. There were no noticeable changes between normothermia and mild hypothermia (32 - 35)°C. However, for moderate hypothermia (28 - 32)°C, there was a remarkable decrease in the oxygen consumption (VO2). The biochemical analysis for renal and liver functions in the normothermia and moderate hypothermia groups showed no significant differences between preoperative and postoperative results. However, in the group with mild hypothermia there was a significant change in results. Conclusion Moderate hypothermia rather than mild hypothermia proves to be of more benefit to the tissues when compared to normothermic conditions, as it significantly reduces tissue oxygen consumption. Moreover, even normothermia was found to be superior to mild hypothermia due to the latter's adverse effects on renal and liver functions while it maintains similar results with regards to oxygen consumption.
