Altitude and cold weather: are they vascular risks?

Area of Science:

• Cardiology
• Environmental Medicine
• Genetics

Background:

• The interplay between high altitude, cold environments, and cardiovascular risk is complex and often intertwined.
• Understanding these unique clinical situations is crucial for effective patient care.

Purpose of the Study:

• To review the latest information on cardiovascular disease associated with high altitude and cold exposure.
• To highlight new findings and their clinical relevance.

Main Methods:

• Literature review of recent studies on high altitude and cold exposure.
• Synthesis of information on evolutionary, genetic, and physiological factors.
• Analysis of reported cardiovascular events and risk factors.

Main Results:

• High altitude and cold affect cardiovascular risk factors, leading to increased myocardial infarction incidence.
• New insights into hematological changes clarify thrombosis risk, including late in-stent thrombosis.
• Research links acute mountain sickness to inflammation and pulmonary edema; chronic mountain sickness involves endothelial abnormalities.

Conclusions:

• High altitude and cold present significant acute, chronic, and public health challenges related to cardiovascular disease.
• Continued research is vital for optimal clinical management in a globalized world.
