Background: Acute Myocardial Infarction (AMI) stands out for its high prevalence. Primary angioplasty is the most effective treatment, in addition to allowing the analysis of coronary perfusion by TIMI frame count (TFC). The severity of AMI is related to worse prognosis and development of left ventricular dysfunction. Objectives: To correlate coronary perfusion after primary angioplasty with post-infarction ventricular function; to describe the demographic characteristics, comorbidities, life habits and family history of the study population; to correlate perfusion after primary angioplasty, post-infarction ventricular function and SYNTAX score (SXs) with each other and with symptom-to-door time, door-to-reperfusion therapy time and total ischemic time; to associate comorbidities, life habits, family history and involvement of the anterior wall with coronary perfusion after primary angioplasty. Method: A cross-sectional study including 55 patients admitted in Santa Catarina’s Institute of Cardiology with diagnosis of AMI with ST-segment elevation, from August to November, 2016. Data collection from interview and consultation in medical records. Analysis by SPSS 13.0, Chi-square test, Student t and p≤0.05. Results: 63.3% were males, mean age 58.39 years. Arterial hypertension (63.3%), family history (47.3%) and dyslipidemia (36.4%) were the most prevalent clinical variables. There was no significant correlation between TFC and left ventricular ejection fraction (LVEF). There was a correlation between TFC and SXs (r=0.31, p=0.041), in addition to a non-significant correlation between SXs and LVEF (r=0.31, p=0.051) and between symptom-to-door time and LVEF (r=0.31, p=0.058). Conclusion: Coronary perfusion is not correlated with post-infarction ventricular function, but SXs is positively correlated with coronary perfusion and has a non-significant correlation with post-AMI ventricular function and symptom-to-door time.
