Introduction and objectives:

macrolides are widely used antibiotics for which a greater frequency of cardiovascular events related to increased arrhythmias has been reported. This study seeks to describe some cardiovascular complications of the use of macrolides in ICU patients.

Materials and methods:

this was a descriptive cross-sectional study which included adult patients admitted to the Medical Intensive Care Unit at the Fundación Cardioinfantil who received antibiotic treatment with clarithromycin in 2013 and 2015.

Results:

the collected sample was 38 patients. The median age was 64 years, and clarithromycin was most frequently used for treating community-acquired infections, with pneumonia being the most common diagnosis. The frequency of atrial fibrillation or flutter was 7.89%, and ventricular tachycardia 2.63%. The most frequently used concomitant medication was quetiapine at 28.95%. The main cause of death was respiratory failure.

Conclusions:

the frequency of arrhythmias was high in our study, although the most frequent cause of death was respiratory failure. (Acta Med Colomb 2020; 45. DOI:https://doi.org/10.36104/amc.2020.1336).
