Introduction:

Cardiovascular diseases claim more lives in the United States than all forms of cancer and chronic lower respiratory diseases combined; and represent 3/4 of the causes of hospitalization in first world countries. Of these, acute myocardial infarction occupies the majority figures.

Objective:

To identify some clinical-echocardiographic and therapeutic variables associated with the presence of complications of acute myocardial infarction lower topography.

Methods:

A retrospective, analytical, case-control study was carried out in patients diagnosed with acute myocardial infarction lower topography, clinical, echocardiographic and therapeutic variables were taken. To determine the prognostic factors of mortality, a binary logistic regression model multivariate analysis was used.

Results:

Age ≥ 65 years which represented 23.93 % of the total, having p value = 0.032 (p ≤ 0.05), 54 % of cases or patients with complications are due to no thrombolytic treatment, a binary logistic regression was performed where variables such as; age ≥ 65 years, non-use of thrombolytic therapy, LVEF < 50% and TDI RV < 9.5 cm/s were more likely to present complications in patients with lower topography infarction.

Conclusions:

Age ≥65 years, female sex, depressed left and right ventricle function correlate with the presence of complications in acute myocardial infarction of lower topography.
