# Thyrotoxic Cardiomyopathy: A Rare Case of Thyroid Storm Presenting as De Novo Heart Failure

## TL;DR

A rare case shows how thyroid storm can cause sudden heart failure and how timely treatment can lead to recovery.

## Contribution

Presents a rare clinical case linking thyroid storm with de novo heart failure and successful recovery.

## Key findings

- A 40-year-old male presented with severe heart failure and thyroid storm.
- Prompt treatment led to clinical improvement and recovery of cardiac function.

## Abstract

Thyroid storm and heart failure represent formidable challenges in clinical practice. Their coexistence, however, poses an even greater threat to the patient's well-being. To facilitate early recognition and appropriate management, an understanding of the complex interplay between these two conditions is crucial. Through comprehensive assessment, vigilant monitoring, and prompt intervention, outcomes can be improved and the morbidity and mortality mitigated. We present a rare case of a 40-year-old male who presented with severe de novo heart failure and a concurrent thyroid storm. Despite an initial left ventricular systolic ejection fraction of 20% and evidence of global dilatation and hypokinesis on echocardiography, appropriate management resulted in improved clinical status and ultimately recovery of cardiac function.
