Good Practices in the Clinical Management of Patients with Acute Coronary Syndrome: Retrospective Analysis in a Third-Level Hospital in Mexico

METHODS: This is a retrospective study including male and female patients aged ≥18 years who were diagnosed with ACS. The collected data included demographic characteristics, risk factors, medications, electrocardiograms, surgical procedures, and in-hospital deaths. RESULTS: There are at least 20% more diagnoses of ST-segment elevation myocardial infarction in this hospital compared to the latest national reports in Mexico. The most common risk factors were type 2 diabetes mellitus, hypertension, smoking, and dyslipidaemia. Diabetic patients with a clinical history of percutaneous coronary intervention had a higher risk of non-ST-segment elevation myocardial infarction than nondiabetics (OR: 2.34; p=0.013), also smoking patients with previous heart surgery than nonsmokers (OR: 7.73; p=0.0007). The average in-hospital mortality was 3.6% for ACS. CONCLUSIONS: There is a higher percentage of coronary interventionism and improvement in pharmacological treatment, which is reflected in lower mortality. The substantial burden of T2DM could be related to a higher number of cases of STEMI. Diabetics with precedent percutaneous coronary intervention and smokers with previous heart surgery have an increased risk of subsequent infarction.
