[Some cardiological problems in high mountains. Correlation with humans in flight]

Area of Science:

• Cardiology
• Environmental Medicine
• Altitude Physiology

Context:

• Cardiovascular health challenges in high-altitude environments.
• Need for specific patient management strategies at different altitudes.
• Impact of altitude on pre-existing cardiac conditions.

Purpose:

• To discuss cardiology problems associated with altitude.
• To suggest dietetic and pharmacological measures for heart patients at high altitudes.
• To define safe altitude limits for cardiac patients based on functional class.

Summary:

• Severe cardiac patients (NYHA Class IV-V), acute myocardial infarction, or serious pulmonary hypertension should not exceed 1,000-1,500 meters.
• Patients with angina, hypertension, or non-severe cardiopathies can manage altitudes up to 3,000 meters.
• Adherence to recommended dietetic and pharmacological interventions is crucial for safe acclimatization.

Impact:

• Provides evidence-based guidelines for managing cardiac patients in mountainous regions.
• Aims to prevent adverse cardiovascular events related to high-altitude exposure.
• Facilitates informed decisions for travel and living in high-altitude areas for individuals with heart conditions.
