Ratios of invasive treatments for different types of myocardial infarction per region
The ratios of invasive treatments were significantly greater for STEMI than for NSTEMI in all regions. The percentages of revascularisation performed in the STEMI group in the WR, CR and ER were 83.0%, 82.5% and 84.6%, respectively; in the NSTEMI group, revascularisation was performed in 54.8%, 55.7% and 58.8% of patients, respectively. In the ER, the ratio of revascularisation was significantly higher than in the other two regions (p < 0.05).
Patient delay, prehospital response time and types of infarction per region
Patient delay and emergency care times were available for 6,878 patients treated for infarction; 3,264 (47.5%) were hospitalised for STEMI (median times are summarised in Table 2 according to diagnosis and regional division). For both types of infarction, the time interval between T1 and T2 was longest in the CR, whereas T3 was the shortest in this region. The median emergency care times were longest in the CR for the STEMI group and the ER for the NSTEMI group (Figure 2 a-b ). TIT was examined in the 3,264 patients with STEMI treated with PCI; unfortunately, this time interval significantly exceeded the optimal value in all three regions. Similar TIT values were observed in the WR and CR (221 and 225 min, respectively), and it was 262 min in the ER. Patient delay was determined in minutes per region (q1; q3): WR, 91 (37.25; 265.5); CR, 97 (34.0; 265.5) and ER, 111 (39.5; 292.5). More than 40% of the TIT was caused by patient delay.
