On December 17th, 2011 local time, Comrade Kim Jong Il, the top leader of North Korea, lost his 69-year-old life due to the sudden onset of acute myocardial infarction, resulting in cardiac shock, ending his 37-year political career. With deep sorrow, she fell into immense sorrow. This spread of bad news also made more and more people pay close attention to heart health and cherish precious life. According to statistics from the National Authority Health Bureau, heart disease ranks second in China's most common fatal diseases, and its incidence shows an alarming growth. The number of deaths due to heart disease in China is nearly 1.8 million every year and it has become the number one killer of human health.

Heart diseases include various heart diseases such as rheumatic heart disease, congenital heart disease, hypertensive heart disease, coronary heart disease, and myocarditis. Among them, the relative incidence of viral myocarditis in myocarditis is very high. Due to different severity of illness, the performance varies greatly. Infants and young children are more severely ill and are lighter in adults, and those with mild symptoms may have no obvious symptoms. Severe ones may have severe arrhythmias, and cardiac insufficiency may even lead to sudden death. The clinical manifestations of mild myocarditis are less and the diagnosis is more difficult, so the pathological diagnosis is far higher than the clinical incidence. In recent years, due to further understanding of the etiology of myocarditis and improvement of diagnostic methods, viral myocarditis has also received increasing attention.

The drugs currently used in the treatment of myocarditis, which are currently available on the market, are anti-viruses and improve symptoms such as arrhythmias. However, they have certain side effects and have low safety factors, which often make patients nervous. The People's Liberation Army Fourth Military Medical University Institute of Pharmaceutical Research has now successfully developed a sustained-release tablet based on cinnamic acid and an oral medicine for the treatment of arrhythmias, which have unique effects on the treatment of viral myocarditis. Cinnamic acid is derived from the extract of cinnamon, a green plant with stable properties. Cinnamic acid is a cinnamic acid antiviral and stable rhythm, dilate blood vessels and other pharmacological activities for the treatment of viral myocarditis and its induced arrhythmia and other symptoms, can effectively reduce the sudden death rate. The medicament has no side effects and is suitable for long-term administration of the patient. It can be safe and effective against viruses, improve the symptoms of myocardial ischemia and stabilize the heart rhythm. Among them, cinnamic acid orally disintegrating tablets are easy to take, and are particularly suitable for infants, children with dysphagia, and emergency patients with sudden arrhythmia episodes.

Since the birth of this research, the market has continued to pay attention. There have been well-known pharmaceutical companies in the country that have produced medical agents for the treatment of viral myocarditis using cinnamic acid as a raw material. The drug caused a lot of hot pursuit of the patients, the reputation is quite good.
