Introduction:

The clinical spectrum of Non-ST-segment elevation Acute Coronary Syndromes includes both asymptomatic patients and those with active ischemia, electrical instability, hemodynamic or cardiac arrest.

Objective:

To evaluate probable predictive factors of non-lethal intra-hospital complications in patients diagnosed with Non-ST-segment elevation Acute Coronary Syndrome.

Material and Methods:

An observational, analytical, cross-sectional study was conducted with a universe of 218 individuals admitted into the Intensive Coronary Care Unit of "Manuel Fajardo" Clinical and Surgical Hospital between 2016 and 2017.

Results:

Male sex predominated (51.4%) and the mean age was 68 years. Arterial Hypertension prevailed as a coronary risk factor. The age showed significant statistical association with the appearance of any complication (p = 0.015) and with hemodynamic complications (p =0,014). The intermediate-high risk, according to the TIMI score, had a statistically significant association with hemodynamic complications (p <0.01).

Conclusions:

Age was statistically associated with the appearance of non-lethal intra-hospital complications. Sex was not associated with complications, nor did the background studied either. Patients with an intermediate-high risk at admission were associated with hemodynamic complications.
