Correlation Analysis Of Red Cell Distribution Width And Fragmented QRS In Acute Coronary Syndrome

ObjectiveBy collecting the red cell distribution width level in patients with acute coronary syndrome and its corresponding 12-lead electrocardiogram (ECG) ,To investigate the relationships between the red cell distribution width level and fragmented QRS waves in acute coronary syndrome.MethodsRetrospective analysis of January 2014 to July 2015 in LINYI People's Hospital of cardiovascular hospitalization in patients with acute coronary syndrome in 90 cases,acute myocardial infarction in 28 case,62 case of unstable angina,including 68 males and 22 females.Diagnosis of acute myocardial infarction and unstable angina are followed by the diagnostic standard guidelines for the prevention and treatment of acute coronary syndrome in China. All patients' careful history inquiry,recording all patients' age,heart rate,blood pressure,history of smoking,diabetes mellitus,high blood pressure,and the number of coronary stenosis,left ventricular ejection fraction,blood glucose,blood lipid indexes.At the same time,red cell distribution width(RDW) and 12-lead ECG were observed.1. According to the standard 12-lead ECG,divided into 2 groups respectively,fragmented QRS wave group and non-fragmented QRS wave group, analysis the difference of clinical characteristics indicators between the two groups of patients.2. According to the standard 12-lead ECG,divided into 2 groups respectively,fragmented QRS wave group and non-fragmented QRS wave group, analysis the difference of RDW values between the two groups of patients.3. Analysis the correlation of RDW values and clinical characteristics indicators in patients with acute myocardial infarction and unstable angina.4.Analysis the correlation of RDW values and fragmented QRS waves in patients with acute myocardial infarction and unstable angina.ResultsThe differences were statistically significant in comparison of age,left ventricular ejection fraction level,red blood cell distribution width value,cardiac troponin between the patients with acute coronary syndrome in fragmented QRS wave and non-fragmented QRS wave (p<0.05).Red blood cell distribution width value in patients with acute myocardial infarction in patients of acute coronary syndrome was positively correlated with age,the number of leads in fragmented QRS(r=0.485,p<0.01;r=0.492,p<0.01).Red blood cell distribution width value in patients with acute myocardial infarction in patients of acute coronary syndrome was negatively correlated with triglycerides,the left ventricular ejection fraction level(r=-0.469,p=0.012;r=-0.544,p<0.01).Red blood cell distribution width value in patients with unstable angina in patients of acute coronary syndrome positively correlated with age,cholesterol (r=0.461,p<0.01;r=0.263,p=0.039),and red blood cell distribution width in patients with unstable angina in patients of acute coronary syndrome was negatively correlated with high density lipoprotein, the left ventricular ejection fraction level(r=-0.317,P= 0.012;r=-0.343,P<0.01)ConclusionThere were differences in Red blood cell distribution width values in patients with acute coronary syndrome of fragmented QRS wave group and in patients with acute coronary syndrome of non-fragmented QRS wave group,red blood cell distribution width values and fragmentation of QRS wave in patients with acute coronary syndrome more closely associated with acute myocardial infarction.
