Timi Risk Score Combined Levin’s Sign In Screening The Acute Coronary Syndrome (ACS) In Patients With Acute Chest Pain

Objective To analyze the ability of screening the acute coronary syndrome (ACS) in patients with acute chest pain using two methods (Levin’s sign-The Thrombolysis in Myocardial Infarction risk score combined with and The Thrombolysis in Myocardial Infarction risk score). Methods171patients were randomly divided into experimental group and control group.81cases were in experimental group (TIMI risk score+Levin’s sign) and90cases were in control group (TIMI risk score). The unified questionnaire and statistical information of patients were collected. According to patients’ TIMI risk score values, it was graded into low (0～2) group, middle (3～4) group and the high (5～7) group. The main role is to analyze the difference of incidence of ACS by two methods in three groups.Results In the low TIMI risk score group (0～2), experimental methods were used in13cases,3cases were diagnosed as acute coronary syndrome(23.08%). The control methods were used11cases,2cases were diagnosed as acute coronary syndrome (18.18%),Both for χ2test,there was no statistically significant difference (P>0.05); In the middle TIMI risk score group (3～4),experimental methods were used in27cases,20cases were diagnosed as acute coronary syndrome(74.07%).The control methods were used33cases,17cases were diagnosed with acute coronary syndrome (51.52%), Both for χ2test,there was statistical significance(P<0.05).In the high TIMI risk score group (5～7), the experimental methods were used in41cases,33cases were diagnosed as acute coronary syndrome (80.49%).The control methods were used46cases,35cases diagnosed as acute coronary syndrome(76.09%), there was no statistically significant difference(P>0.05). In the middle group, the joint TIMI risk score and Levin sign were compared with gold indicators coronary angiography, it found that the sensitivity of the joint TIMI risk score and Levin sign in the diagnosis of ACS was86.84%, the specificity was90.91%, the diagnostic coincidence rate was88.33%, P<0.001.Conclusion In the middle group, there is higher incidence of acute coronary syndrome if we apply the Levin’s sign into TIMI risk score, it will predict the occurrence of ACS more exactly, and it maybe a simple and effective tool for ACS screening in patients with acute chest pain.
