The Time Interval between Onset of Symptoms to Primary Percutaneous Coronary Intervention (PPCI) and its Contributing Factors in Patients with Acute Myocardial Infarction in Tabriz and Urmia Heart Centers in 2017

Abstract

Abstract: Background & Aim: Door-to-balloon time is an important variable on the extent of the necrotic area, the severity of cardiac damage and the consequences of primary angioplasty in patients with acute myocardial infarction. This study aimed to determine the time intervals from the moment of arrival in the emergency department until performing primary angioplasty in patients with acute myocardial infarction was performed. Methods & Materials: This descriptive cross-sectional study was performed on 191 patients with acute myocardial infarction treated by primary angioplasty in the Madani hospital of Tabriz and Seyed-al-Shohada hospital of Urmia. In this study the sampling method was convenient and the data gathering tools were included a researcher-made checklist containing 15 items related to demographic characteristics, history of disease and risk factors, type of transmission, type of pain and myocardial infarction, general condition and time actions and causes of delayed. After determining the validity and reliability of the tools, the data were collected and analyzed by statistical software Spss/16. Results: The mean age of participants was 57.41 ± 13.67. The mean time interval from the moment of arrival in the emergency department until requesting of the primary angiography 66.62 ± 66.67 minutes, and from the moment of arrival in the emergency department until the transfer to the catheterization laboratory or Cath lab unit (Door-to-balloon) 76.15 ± 48.48 minutes were obtained. There was a significant difference between the type of acute myocardial infarction and the mean door-to-balloon time (P= 0.008). Also, there was no significant difference between the mean door-to-balloon time in the work shifts of the morning, evening and night (P = 0.66). Conclusion: The mean door-to-balloon time in patients with acute myocardial infarction referred to the cardiac centers in northwestern Iran was within the standard range.
