Abstract
Background. There is little known about whether characteristics and outcomes of patients with acute myocardial infarction (AMI) have changed over the years in non-PCI capable hospitals in real-life. Our aim was to assess them between 2007 and 2014. Methods. It was a retrospective cohort study. Characteristics and in-hospital mortality (standardized in cases of different characteristics between the groups by original simple method) were assessed for all patients with non-ST elevation myocardial infarction (NSTEMI) and ST elevation myocardial infarction (STEMI) at two non-PCI capable hospitals: one in 2007 (n = 104) and another in 2014 (n = 58). Results. In 2014, females were older than in 2007 (80.18 ± 7.54 versus 76.15 ± 8.77, p = 0.011), males were younger (71.61 ± 11.22 versus 79.20 ± 7.63, p = 0.019), less had renal failure (RF) (19% versus 34.6%, p < 0.0001) and reinfarction (13.8% versus 35.6%, p < 0.0001), and the proportion of males (31% versus 43.3%, p = 0.001) and the proportion of NSTEMI (60.3 versus 69.2, p < 0.0001) decreased. In cases of STEMI there were no differences in patient characteristics. STEMI (18.8% versus 21.7%) and standardized mortalities by gender, RF, and reinfarction NSTEMI (19.47%, 15.34%, and 17.5%, resp., versus 17.1%) showed no differences between 2007 and 2014. Conclusions. There were some differences in patient characteristics but not in mortality for AMI at non-PCI capable hospitals between 2007 and 2014.
Highlights
There is little known about whether the clinical and demographical characteristics and in-hospital mortality of patients with acute myocardial infarction (AMI) have changed over the years in non-PCI capable hospitals in real-life.It was shown that life expectancy continues to increase [1, 2]
Patients hospitalized at the Republican Hospital of Kaunas (RHK) in 2014 with the diagnosis of an AMI in comparison with the patients hospitalized at the Kaunas Clinical Hospital (KCH) in 2007 were different in some characteristics: females were older, but males were younger, and less of the patients had renal failure (RF) and reinfarction (Table 1)
In 2007 in KCH non-ST elevation myocardial infarction (NSTEMI) was more frequent than ST elevation myocardial infarction (STEMI), 69.2% versus 30.8%, p < 0.0001, while in 2014 in RHK the prevalence of NSTEMI was insignificant, 60.3% versus 39.7%, p > 0.05
