This research tries to the rate of arrhythmia manifested during the first (48) hours of heart infarction and define its nature as well as its relationship with heart infarction in regard to patients subjected to anti-coagulation (streptokinase) therapy and patients who were not subjected to it. Moreover, it also aims to detect the relationship between arrhythmia and the death rates of the patients during their stay in the Heart Intensive Care Unit. The study started in October 2012 and lasted twelve months, up to October 2013. The sample of study here consisted of (187) patients hospitalized in the Heart Intensive Care Unit having acute myocardial infarction. The sample included (142) males (76 % of the sample) and (45) females (24%). The research reached the following findings: A hundred and seven of the patients monitored in the study were smokers; and smoking was the most important risk factor causing myocardial infarction. Ventricular extra systole were the most common symptoms of acute myocardiac infarction arrhythmia during the first (48) hours of hospitalization reaching (79%). The second was increased auto ventricular rhythms rating (43 %). High rates of dangerous arrhythmia like (VT) and (VF) rating (9%) in patients who were not subjected to streptokinase (anti-coagulation) compared with those subjected to it (4. 5%), and (3.8) respectively. Decreased (EF) increased the possibility of life-threatening ventricular arrhythmia like (VT). Diabetes did not increase the dangers of arrhythmia monitored in this research

Research summary
تهدف هذه الدراسة إلى تقدير نسبة حدوث اضطرابات النظم خلال الـ 48 ساعة الأولى من احتشاء العضلة القلبية وتحديد نوعها وعلاقتها مع نمط الاحتشاء وموقعه، سواء عند المرضى الذين طبق لهم علاج حال للخثرة أو الذين لم يطبق لديهم، وكذلك تحديد علاقتها مع نسبة الوفيات خلال فترة إقامة هؤلاء المرضى في العناية القلبية المشددة. بدأت الدراسة في أكتوبر 2012 واستمرت لمدة 12 شهراً، وشملت 187 مريضاً، منهم 142 ذكوراً و45 إناثاً. أظهرت النتائج أن التدخين هو العامل الأهم للإصابة باحتشاء العضلة القلبية، وأن خوارج الانقباض البطنية هي أشيع اللانظيمات الحاصلة خلال الـ 48 ساعة الأولى من الاحتشاء. كما بينت الدراسة أن اضطرابات النظم الخطيرة مثل التسرع البطيني والرجفان البطيني كانت أكثر شيوعاً لدى المرضى الذين لم يطبق لهم الستربتوكيناز مقارنة بالذين طبق لهم. وأظهرت الدراسة أيضاً أن الإصابة بالداء السكري لا تزيد من خطورة الإصابة باضطرابات النظم المراقبة في الدراسة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة جداً لفهم العلاقة بين اضطرابات النظم واحتشاء العضلة القلبية، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الممكن توسيع عينة الدراسة لتشمل عدد أكبر من المرضى للحصول على نتائج أكثر دقة. ثانياً، لم تتناول الدراسة بشكل كافٍ العوامل البيئية والاجتماعية التي قد تؤثر على نتائجها. ثالثاً، كان من المفيد تضمين تحليل مقارن بين مختلف أنواع العلاجات المتاحة لاحتشاء العضلة القلبية وليس فقط التركيز على الستربتوكيناز. وأخيراً، كان من الممكن تقديم توصيات أكثر تفصيلاً حول كيفية تحسين الرعاية الطبية للمرضى الذين يعانون من احتشاء العضلة القلبية.
Questions related to the research
  1. ما هي النسبة المئوية للمرضى الذين كانوا مدخنين في الدراسة؟

    57% من المرضى كانوا مدخنين.

  2. ما هي أشيع اللانظيمات الحاصلة خلال الـ 48 ساعة الأولى من احتشاء العضلة القلبية؟

    أشيع اللانظيمات هي خوارج الانقباض البطنية بنسبة 79%.

  3. هل يزيد الداء السكري من خطورة الإصابة باضطرابات النظم؟

    لا، الإصابة بالداء السكري لا تزيد من خطورة الإصابة باضطرابات النظم المراقبة في الدراسة.

  4. ما هو تأثير الستربتوكيناز على نسبة حدوث اضطرابات النظم الخطيرة؟

    الستربتوكيناز يقلل من نسبة حدوث اضطرابات النظم الخطيرة مثل التسرع البطيني والرجفان البطيني.

Background: primary percutaneous coronary intervention PCI is the treatment of choice in civilized countries for acute myocardial infarction, the aim of the treatment here is the revascularization as soon as possible. Patients and methods: it is re trospective study of 133 patients of acute MI have been divided into two subgroups. The first subgroup has been treated with streptokinase infusion, and the other subgroup has beet treated by PCI. We monitored the patients within hospitalization , reinfarction, mortality, cardiogenic shock, heart failure, also we recorded the time needed to apply the method of treatment and Timi score by diagnostic cardiac catheterization after applying the treatment. Aim of study: to compare between streptokinase and PCI in our hospitals to know which way is better in which we can give the best medical care for this critical patients. Results: 63 patients undergo to pci and 70 patients undergo to streptokinase therapy. Streptokinase group had higher rates in mortality for noncardiac reasons 100%, cardiogenic shock 60% , reinfarction 81%, mortality for cardiac reasons 80%, while it was faster in applying the treatment and equal to pci in timi score. While pci group has higher rated in hospitalization for cardiac reasons 70% and in cases that has new congestive heart failure 63%, and nearly equal to streptokinase group in timi score. Conclusion: pci was better in mortality and cardiogenic shock and reinfarction than streptokinase but it was worse in hospitalization for cardiac reasons and congestive heart failure cases . pci was too late than streptokinase in applying the treatment . we notice that the two methods of treatment was nearly equal in timi score.
Study has been made on 121 patients affected by myocardial infarction ( MI ) in Damascus university hospitals whereas the patients were divided in tow groups : the first group contained 60 patients treated traditionally without captopril. the seco nd group contained 61 patients treated traditionally and by captopril these patients were examined by Echo – Doppler during the acute phase and after six months of MI to realize the effect of captopril on contractility and function of left ventricular (LV) .
Introduction: The cardiogenic chock is the most cause of death following to acute myocardial infarction (IMA) ,it occurs( 10%) in patients who are hospitalized in soins intensive for acute myocardial infarction Lot of patient with acute myocardial infarction develops cardiogenic shock after arriver to hospital The cardiogenic chock with STEMI (7.5%) is more than its with NSTEMI (2.5%) The cardiogenic chock occurs in diabetic patients two field more than non diabetic patient may the prognosis is the same Study methods: our study is retrospective has been done in soins intensive in University Alassad hospital in Lattaquie It includes all patients admitted for acute myocardial infarction pendant the period from January 2014 to January 2016 Results :The percentage of cardiogenic shock in our study is( 12%) .(29.4%)of them are arrived to hospital with cardiogenic shock while( 70.6%) developed cardiogenic shock pendant their hospitalization The responsible pathologies of cardiogenic shock were as following: left ventricular dysfunction (58%) isolated right ventricular shock( 24% ) acute mitral valve insufficiency (11%),septa l interventricular rupture(5%)
We studied 67 cases of left ventricular aneurysm following a myocardial infarction through 1993 to 2002. 22 Patients had only aneurysmectomy 45 Patients had aneurysmectomy + CABG + Mitral surgery. Death percentage in the first year after surgery was 8.9 %. The good clinical and haemodynamical results are due to the clear indication of surgery on patients who had more than 25% of the LVDV involved by aneurysm.
This paper presents our system for the Quantity span identification, Unit of measurement identification and Value modifier classification subtasks of the MeasEval 2021 task. The purpose of the Quantity span identification task was to locate spans of text that contain a count or measurement, consisting of a value, usually followed by a unit and occasionally additional modifiers. The goal of the modifier classification task was to determine whether an associated text fragment served to indicate range, tolerance, mean value, etc. of a quantity. The developed systems used pre-trained BERT models which were fine-tuned for the task at hand. We present our system, investigate how architectural decisions affected model predictions, and conduct an error analysis. Overall, our system placed 12 / 19 in the shared task and in the 2nd place for the Unit subcategory.
