# Hyperhomocysteinemia Causing Myocardial Infarction in a Young Patient: A Case Report

## TL;DR

A young man with no typical risk factors had a heart attack due to high homocysteine levels, highlighting this as a potential cause in young patients.

## Contribution

This case emphasizes hyperhomocysteinemia as a novel risk factor for myocardial infarction in young individuals.

## Key findings

- A 19-year-old male with a marfanoid phenotype experienced acute MI without conventional risk factors.
- Hyperhomocysteinemia was identified as the likely cause of the myocardial infarction in this young patient.

## Abstract

Hyperhomocysteinemia is an independent risk factor for acute myocardial infarction (MI). This case report describes a 19-year-old male with a marfanoid phenotype and no conventional risk factors presenting with acute MI. It highlights the significance of acknowledging hyperhomocysteinemia as a potential risk factor for MI, especially in young patients.
