Introduction: The identification of patients with acute coronary syndrome (ACS) among the large proportion of patients with suspicion of cardiac pain is a challenge for the internist, especially in those cases without clear symptoms or typical electrocardiographic findings. Objective: To determine the clinical and epidemiological characteristics of patients with ACS Materials and methods: Cross-sectional retrospective observational study, based in the revision of thirty clinical records of patients with ACS admitted into the II Chair of Medical Clinic of the Clinic Hospital during 2013. Results: There was a predominance of men (57%) and most patients came from the Central Department (76%). The most frequent cardiovascular risk factors were arterial hypertension (AHT) (80%) and diabetes mellitus (DM) (50%). The most frequent Killip classification at the admittance time in Emergency was I (63%). The Non-ST Segment Elevation Acute Coronary Syndrome (NSTE-ACS) prevailed: 22 cases (73%), with a mean age of 64 years and 11 days of hospitalization. The dominant clinical presentation was the typical angina (59%). The most frequent final diagnoses were unstable angina (59%) and acute infarction (27%). The prevailing TIMI was moderate (50%) and high (36.36%) while mortality was 9%. The other clinical profile (n=8) was the ST Segment Elevation Acute Coronary Syndrome (STE-ACS), with a mean age of 67 years and mean time of hospitalization of 13 days. All of these presented typical angina, the final diagnosis was acute myocardial infarction in 75% of them and half received medical treatment and the other half reperfusion with fibrinolytic therapy, mainly alteplase. There was no mortality in this group. Conclusion: Male gender prevailed, most of them with HTA and DM. The most frequent ACS was NSTE-ACS (75%) that was seen in younger subjects and with 9% mortality.
