Angina is chest pain or discomfort due to inadequate blood flow to the heart. The lower frontal lobe of the brain is involved in the stress response. This study was aimed at determining the degree of influence of stress and other psychological factors in the diagnosis and treatment of angina pectoris.
The study involved 148 people, while 69 percent of them were men, 31 percent were women. Participants were assessed using three methods over two weeks: a psychological stress test with brain imaging, the same test but with cardiac imaging, and a test that included exercise or chemical stress.
During the study, doctors assessed the participants' level of chest pain. The researchers concluded that those subjects who reported regular chest pain had higher lower frontal lobe activity in response to mental stress. A correlation was also found between the activity of the lower frontal lobe during stress and the change in the frequency of angina attacks over two years.
The researchers were surprised at how often activation of the frontal lobe of the brain was associated with bouts of chest pain. These factors, recorded in angina pectoris, were somehow associated with stress: be it activation of the lower frontal lobe of the brain, symptoms of depression, or post-traumatic stress disorder. Scientists have found that very causal relationship between the brain's response to stress and the development of angina pectoris, which in the future will provide an invaluable service in the treatment of angina pectoris.
