Cardiovascular disease has become the number one killer of health, and those over 40 years old are a high-risk group

Changsha, July 7 (Reporter Dong Lei, Correspondent Wu Ximing, Luo Wen) In recent days, Changsha has experienced continuous high temperatures above 35°C, which is not good news for patients with cardiovascular disease. Professor Liu Suixin, director of the Rehabilitation Department and Cardiovascular Disease Rehabilitation Center of Xiangya Hospital, said today that overheating or overcold weather can easily induce cardiovascular disease, and middle-aged and elderly people should pay special attention to it.

According to statistics from the World Heart Federation, cardiovascular and cerebrovascular diseases, which have the "four worst", are currently the diseases with the highest incidence rate, highest mortality rate, highest disability rate, and most complications in the world, causing 17.5 million deaths worldwide every year.

In recent years, the incidence rate has been on a linear upward trend, and the age of onset has been significantly earlier.
