Panic attacks and heart attacks have many of the same symptoms, some heart attacks occur due to physical exertion.

The blockage in one or more blood vessels to the heart, which leads to disruption of vital blood flow, provokes a heart attack.

Although panic does not cause a heart attack, stress and anxiety can still contribute to the development of coronary heart disease.

Panic attacks can occur as a separate condition or part of an anxiety disorder.

Some studies indicate that, people with anxiety disorders may have an increased risk of developing heart disease due to low heart rate variability (HRV).

Heart rate variability is the time between each heartbeat. The autonomic nervous system controls the heart rate.
