Complications and Comorbidities in Elderly Patients with Acute Coronary Syndrome

Background: Elderly patients present with acute coronary syndrome (ACS) are frail with multiple complications and comorbidities, this contributes to the poor outcome of heart failure (HF).
Results: Mean age in the I^st group was 65,1±3,07 years (120 patients), II^nd group – 84,25±3,24 years (130 patients). Hospitalisation lenght was longer in the II^nd group (8,03±4,17>6,49±3,45 days) (p<0,001; r=0,228). The most common ACS complication is HF (87,6 %) (p=0,806), among NYHA classification II^nd group was ranked higher than I^st group (p=0,024). 25,5 % of patients in I^st group had arrythmias, 74,5% in II^nd group (p=0,001). The statistically significant differences in renal failure occurrence were determined (p <0.001). Mild renal failure was found in 15.7% in I^st group, 84.3% in II^nd, moderate - 70.4% in I^st group, 29.6% in II^nd; Severe renal failure - 98.0% in I^st group, 2% in II^nd. Distribution of diabetes was statistically significant p=0,022. 36,8% patients had pure hypercholesterolemia, mixed hyperlipidemia - 42,8%, between groups p=0,966; p=0,089.
Conclusions: II^nd group had more complications, which had an impact in their longer hospitalisation period. An uneven distribution of renal failure in both groups was determined. Among the included comorbidities, there were significantly more patients who had diabetes in II^nd group.
