Heart disorders and stress play an important role in a human’s life. With the constantly changing lifestyle and environmental factors, humans are highly prone to various health conditions drastically affecting their daily activities. Poor diet, lack of exercise, and alcohol abuse have a major impact on the cardiac health of an individual. Irrespective of the health conditions, an individual is susceptible to stress due to various causes. Sometimes the impact of stress may last longer than usual, resulting in post-traumatic stress disorder. Stress keeps the body alert and brings out a fight and flight response. This can affect the heart as it pumps extra blood during stressful conditions to compensate for the stressful situation.

In the long term, stress can affect the functions of the heart and cause various cardiovascular diseases. Hence, it is important to understand the relationship between post-traumatic disorder and cardiovascular risk to understand the outcome of the condition better and treat it accordingly.
