Background:

Early surgical procedures on patients with infective endocarditis (IE) have shown a clearly benefit to reduce embolization at the central nervous system. We conducted a retrospective cohort in Mexican population to evaluate mortality and clinical outcomes in patients with IE with or without surgical intervention.

Objectives:

Our aim was to evaluate factors associated with mortality in patients with IE and compare both groups with and without a surgical intervention.

Methods:

We evaluated a retrospective cohort of patients who had been diagnosed with IE according to the Duke’s criteria at our Institution in SLP, Mexico, from January 2001 to September 2016. We compared the risk factors associated to mortality of patients with or without surgery. Our primary outcome was mortality within 6 months of follow-up after the diagnosis.

Results:

We included 105 patients, 51 (48.6%) were men, median age 46 [Q1 30, Q3 59] years, 36 patients (34.3%) received surgical treatment (STG), and 69 (65.7%) only medical treatment (MTG) group; 41 patients (39%) died during the study period; in the surgery group eight patients died (22%); and 33 in the MT group (47%) p = 0.049. Adjusted for APACHE II, surgery, creatinine levels and the size of vegetation, the surgery group had lower mortality than patients on MTG (HR 0.36, p = 0.047).

Conclusion:

As previously described in the literature, patients who underwent surgery had lower mortality than the patients who only received medical treatment; however, the Mexican population is different to other populations group, due to higher risk of diabetes mellitus (28%) versus (10%) in global risk of DM in the world and its complications and other chronic diseases as arterial systemic hypertension. Thus, surgical treatment must be elected as goal standard treatment in patient’s whit IE and presence of vegetation.
