Cardiovascular diseases are the leading cause of death in many countries. While their classic determinants are well identified, the influence of environmental factors—particularly temperature—remains insufficiently integrated into prevention strategies. Yet exposure to extreme climatic conditions may significantly modulate the risk of cardiovascular events.
Quantifying the impact of cold on mortality
A study published on March 24 in the American Journal of Preventive Cardiology and presented at the annual congress of the American College of Cardiology (ACC.26) aimed to comprehensively assess the association between ambient temperatures and cardiovascular mortality in the United States. It addresses a gap in large-scale data, as previous research was often limited to specific regions or populations.
