BLANCO, Federico et al. Delay in Performing Primary Angioplasty: Is it due to a Reason Related to the Patient or to the Healthcare System?. Rev. argent. cardiol. [online]. 2009, vol.77, n.1, pp. 14-20. ISSN 1850-3748.
Introduction One of the inconveniences in the general utilization of primary angioplasty (PCTA) is the delay in its application. Most of present data come from clinical trials from other countries, whereas little is known about its application in the regular practice in our country. Objectives To analize the periods of time needed for each stage of a PCTA in a facility where the election treatment is used as a first step for a time-optimization program, and to determine if the delay is due to a situation related to the patient or to the healthcare system. Material and Methods This is a prospective observational study in patients with AMI of less than 12-hours since onset. The "patient time" was counted from the onset of the symptoms to the arrival in hospital, and the "medical care time" was determined from the arrival in hospital to the balloon inflation. Results PCTA was performed in 224 patients admitted with diagnosis of AMI. The median values (25th to 75th percentile) were "patient time": 60 minutes (40-150), "medical care time": 93 minutes (72-128). The "medical care time" includes: time 1 (arrival in hospital-call for the hemodynamics team): 20 minutes (10-45), time 2 (call for the hemodynamics team-admittance in hemodynamics room): 38 minutes (23-52), time 3 (admittance in hemodynamics roomirst inflated balloon): 31 minutes (21-45). Conclusions The "patient time" represents less than half the total time consumed. The "medical care time" determines the higher delay for the procedure; therefore, more emphasis should be placed in improving this time, within which the time for calling for the first balloon is a key factor.
