The Impacts of The Earthquake on The Cardiovascular System

Abstract

Introduction: Various physiological and psychological effects of earthquakes can be seen on the human body, even without a direct physical impact from the earthquake. Both the experience of the earthquake process and the earthquake-related subsequent life changes cause stress through the activation of the sympathetic and parasympathetic systems in the body. This stress can affect various physiological processes, including the cardiovascular system. In this review, the effect of earthquakes on the cardiovascular system was aimed to be discussed in line with the available evidence. Discussion: There are studies showing that natural events such as earthquakes increase the incidence of adverse cardiac events, such as myocardial infarction, heart failure, hypertension, and sudden cardiac death, or cause existing cardiac diseases to worsen during these periods. However, there are also some evidences with conflicting results. Therefore, the effect of earthquakes on cardiovascular diseases has not been clearly demonstrated yet. Conclusion: Even survivors of earthquakes without physical injury are exposed to stress secondary to both internal and external factors. Studies indicate that individuals who are involved in the earthquake process may have adverse effects on cardiovascular health in the short and long term. Therefore, it is important to take necessary precautions and create appropriate conditions, especially in people with cardiovascular disease.
