Introduction:

Age represents one of the greatest predictors of risk of cardiovascular complications in patients with acute coronary syndrome. The prevalence of this syndrome in the group of octogenarian patients is high.

Objective:

To characterize the population of octogenarian patients with acute coronary syndrome and the possible associations between the occurrence of non-lethal intrahospital complications and cardiovascular risk factors.

Methods:

This is a prospective analytical cohort study of all patients admitted to the intensive coronary care unit of Manuel Fajardo University Hospital in Havana, from 2016 to 2020.

Results:

The female sex (64.2%), a history of arterial hypertension (89.7%), ischemic heart disease (66.7%), and smoking habits (32%) outweighed. Significant statistical associations were found between the type of acute coronary syndrome and the presence of cardiovascular complications of any type (p=0.006); the increase in creatinine was associated with the presence of hemodynamic complications (Mdn=97; Range=97.52; p=0.012), as well as the left ventricular ejection fraction showed a highly significant association with the presence of cardiovascular complications of any type (Mdn=59; Range=63.3; p<0.001) and hemodynamic (Range=55.2; p<0.001).

Conclusions:

The octogenarian population of patients with ST-segment elevation acute coronary syndrome was characterized and was associated with an increase in in-hospital cardiovascular complications, in the same way that it happened with the value of the left ventricular ejection fraction.
