Seasonal variations in cardiovascular disease

Area of Science:

• Environmental Health
• Cardiology
• Public Health

Background:

• Cardiovascular disease (CVD) exhibits seasonal patterns, with increased events during cold weather and heat waves.
• Individuals in milder climates may be particularly susceptible to seasonal CVD variations.
• Seasonal CVD trends result from complex interactions between environmental conditions and individual physiology and behavior.

Purpose of the Study:

• To review physiological and environmental factors contributing to cardiovascular seasonality.
• To highlight global population study findings on CVD seasonality.
• To describe strategies for mitigating seasonal cardiovascular event peaks.

Main Methods:

• Literature review of physiological and environmental factors.
• Analysis of large-scale global population studies on CVD seasonality.
• Synthesis of potential intervention strategies.

Main Results:

• Consistent winter peaks and clusters of CVD events after cold snaps are observed globally.
• Heat waves are also linked to increased cardiovascular events.
• Behavioral and physiological responses to seasonal changes significantly influence CVD susceptibility.

Conclusions:

• Seasonal variations significantly impact cardiovascular disease incidence.
• Multifaceted interventions targeting environmental and behavioral factors can reduce CVD risks during extreme weather.
• Further recognition and research are needed to address seasonal CVD provocation.
