Patients with a heart attack often reach the emergency anxious and very nervous because of the sudden and unexpected onset of their symptoms. However, anxiety and stress can be a cause of heart attacks as well. Either as a cause or as a consequence of heart attacks, it is a widespread symptom in these patients, and it often contributes to the severity of the cardiac event.
When patients become too anxious and nervous about their condition, their heart starts to pump faster and harder, increasing the activity and the energy requirements of this organ. Since there’s already insufficient blood flow to some regions of the heart, this increase in energy requirements will not be met by the coronary arteries, and the damage to the cardiac muscle becomes more extensive.
