[In-hospital Outcomes and Complications of Percutaneous Coronary Interventions in Acute ST-Elevation Myocardial Infarction in Different Age Groups].

Aim: to assess early (in-hospital) results of percutaneous coronary intervention (PCI) for ST-elevation (STE) myocardial infarction (MI) in different age groups.

Materials And Methods: We enrolled in this study 356 patients with STEMI who underwent PCI within 24 hours of the disease during 1 year (2012). According to age all patients were divided into 2 groups: "young" ( less or equal 70 years) and "older" (>70 years).

Results: Compared with young in older group there were more patients with renal (53.84 vs. 19.78%) and myocardial (23.07 vs. 6.83%, =0.0000) dysfunction, hypertension (97.43 vs. 83.81% =0.0018), history of MI (19.23 vs. 10.43%, =0,3736), and acute heart failure at admission (32.04 vs. 13.95%, =0.0003), and less smokers (10.25 vs. 34.53%). Hospital mortality in older group was higher (8.97 vs. 1.43%, =0.0007) despite effective PCI. Rate of hemorrhagic complications (major bleedings+hemotransfusions) was also higher in older group (5.12 vs. 0.71%, =0.0077).

Conclusion: Compared with younger older STEMI patients were characterized by more severe initial clinical condition and worse early results of primary PCI with higher mortality and rate of hemorrhagic complications. Thus the problem of improvement of management of this group of patients during hospitalization remains to be actual.
