High Altitude Pulmonary Edema Without Appropriate Action Progresses to Right Ventricular Strain: A Case Study

Area of Science:

• Altitude Medicine
• Cardiology
• Pulmonology

Background:

• High altitude pulmonary edema (HAPE) is a serious condition affecting individuals at high elevations.
• Understanding the progression and physiological impact of HAPE is critical for effective management.

Purpose of the Study:

• To present a case study of HAPE development and its progression.
• To highlight the cardiac implications, specifically right ventricular strain, associated with HAPE.
• To emphasize appropriate management strategies for HAPE.

Main Methods:

• Case report of a 24-year-old male experiencing HAPE after ascending to 4061m.
• Clinical assessment including symptom evaluation, vital signs, ECG, and chest X-ray.
• Analysis of the patient's response to continued ascent versus rest and descent.

Main Results:

• The patient developed HAPE with symptoms including dyspnea, chest pain, and headache.
• Hospitalization revealed hypoxemia, tachycardia, hypertension, and ECG findings of right ventricular strain.
• Chest X-ray showed right lower lobe infiltrates, consistent with pulmonary edema.

Conclusions:

• HAPE can occur in individuals without prior history under specific precipitating conditions.
• Continued exertion at altitude during HAPE does not promote acclimatization and can exacerbate the condition.
• Rest and descent are the recommended interventions for HAPE, which can lead to significant right ventricular strain.
