Abstract
Global warming, driven by increased greenhouse gas emissions, has led to unprecedented extreme weather events, contributing to higher morbidity
and mortality rates from a variety of health conditions, including cardiovascular disease (CVD). The disruption of multiple planetary boundaries has
increased the probability of connected, cascading, and catastrophic disasters with magnified health impacts on vulnerable populations. While the
impact of climate change can be manifold, non-optimal air temperatures (NOTs) pose significant health risks from cardiovascular events.
Vulnerable populations, especially those with pre-existing CVD, face increased risks of acute cardiovascular events during NOT. Factors such as
age, socio-economic status, minority populations, and environmental conditions (especially air pollution) amplify these risks. With rising global sur face temperatures, the frequency and intensity of heatwaves and cold spells are expected to increase, emphasizing the need to address their health
impacts. The World Health Organization recommends implementing heat–health action plans, which include early warning systems, public educa tion on recognizing heat-related symptoms, and guidelines for adjusting medications during heatwaves. Additionally, intensive care units must be
prepared to handle increased patient loads and the specific challenges posed by extreme heat. Comprehensive and proactive adaptation and miti gation strategies with health as a primary consideration and measures to enhance resilience are essential to protect vulnerable populations and re duce the health burden associated with NOTs. The current educational review will explore the impact on cardiovascular events, future health
projections, pathophysiology, drug interactions, and intensive care challenges and recommend actions for effective patient care.
