Climate Change Could Triple Cardiovascular Disease Burden by 2050
HEAT exposure could drive a dramatic rise in cardiovascular disease (CVD) burden across the USA over the next 25 years, with researchers warning that climate change and population ageing may combine to reverse decades of progress in heart health.
Heat Exposure Threatens Future Heart Health
A new modelling study estimated that heat-attributable CVD burden could more than triple by 2050 under a high greenhouse gas emissions scenario, disproportionately affecting older adults and economically disadvantaged communities.
CVD remains the leading cause of death in the USA, and growing evidence suggests that rising temperatures are becoming an increasingly important contributor to heart-related illness and mortality. Excessive heat places additional strain on the cardiovascular system, increasing the risk of conditions such as myocardial infarction, stroke, and heart failure.
To assess the potential impact of climate change on cardiovascular health, researchers analysed county-level data from 3,108 counties across the contiguous USA. Baseline estimates were derived from data collected between 2010–2016 and used to project future heat-attributable CVD burden in 2030 and 2050 under moderate and high greenhouse gas emissions scenarios.
