Acute Coronary Syndrome Manifesting as an Adverse Effect of All-trans-Retinoic Acid in Acute Promyelocytic Leukemia: A Case Report with Review of the Literature and a Spotlight on Management

Abstract EN

Background.

Acute promyelocytic leukemia is characterized by t(15;17).

This leads to the formation of PML/RARα which blocks the differentiation of blasts at the stage of promyelocytes.

This is reversed by all-trans-retinoic acid (ATRA), a vitamin A derivative.

Acute myocardial ischemia is a rare side effect of ATRA.

Case Report.

We report a case of acute coronary syndrome manifesting as an adverse effect of ATRA in a lady with APL who had no other risk factors for cardiovascular disease.

Conclusions.

We emphasize the need for high index of suspicion for the diagnosis of this entity.

In the light of this case, the rare instances of ATRA associated acute myocardial ischemia recorded in the literature and the options available for treatment of acute promyelocytic leukemia sans ATRA have been reviewed.
