: Globally, hot weather and heatwaves are claiming lives and are predicted to become increasingly deadly under all future climate change scenarios. Rising global temperatures pose a significant risk on cardiovascular health, disproportionately impacting the elderly and people with cardiovascular disease (CVD). However, despite convincing epidemiological data demonstrating this increased cardiovascular risk, the physiological mechanisms that underpin this risk are less known. Exposure to elevated temperatures leads to increased inflammation, myocardial oxygen demand and dehydration, predisposing people to myocardial stress. Additionally, health and social inequities like low income, poor housing and limited access to cooling further exacerbate the health risks during heatwaves. This scientific statement provides a comprehensive discussion on the epidemiological evidence of heat-related CVD, the human physiological responses to hot environments, the impact of heat on cardiovascular health, and the relative impact of social inequalities. Finally, an agenda is provided that calls for research to understand and reduce the health risks associated with heatwaves for people with CVD.

Abstract
: Globally, hot weather and heatwaves are claiming lives and are predicted to become increasingly deadly under all future climate change scenarios. Rising global temperatures pose a significant risk on cardiovascular health, disproportionately impacting the elderly and people with cardiovascular disease (CVD). However, despite convincing epidemiological data demonstrating this increased cardiovascular risk, the physiological mechanisms that underpin this risk are less known. Exposure to elevated temperatures leads to increased inflammation, myocardial oxygen demand and dehydration, predisposing people to myocardial stress. Additionally, health and social inequities like low income, poor housing and limited access to cooling further exacerbate the health risks during heatwaves. This scientific statement provides a comprehensive discussion on the epidemiological evidence of heat-related CVD, the human physiological responses to hot environments, the impact of heat on cardiovascular health, and the relative impact of social inequalities. Finally, an agenda is provided that calls for research to understand and reduce the health risks associated with heatwaves for people with CVD.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
