Functional heart disease is the opposite of organic heart disease, which refers to having certain cardiovascular symptoms, such as palpitations, pain in the precordial region, chest tightness, and shortness of breath. However, various tests, such as electrocardiogram, blood lipids, cardiac CT and cardiovascular imaging, do not show any evidence of myocardial ischemia, but the symptoms become more pronounced during emotional stress. This type of patient is common in young people, but also in office workers and empty nesters, and is generally related to disorders in the regulation of vegetative nerves. The symptoms of functional heart disease may appear if there is a sudden increase in the amount of exercise after the usual decrease in activity. Most of these groups have a history of mental trauma, or excessive work stress. In addition to the above symptoms, some people are accompanied by insomnia, dizziness, and weakness. Treatment should be based on the selection of drugs for different accompanying symptoms; if accompanied by dizziness, weakness, and irritability, you can take Easy-going Pill; if accompanied by insomnia, you can take Tianwang Tonic Heart Pill.
