Is “Empress Dowager He was pushed down the stairs by Li Ru and died” true?

In Chapter 4 of Romance of the Three Kingdoms, the process of Empress Dowager He being killed by Li Ru, sent by Dong Zhuo, is described in detail: "Li Ru flew into a rage, grabbed the Empress Dowager with both hands, and threw her down the stairs, then ordered Tang Fei to be strangled, and poisoned Emperor Shao with wine, and reported back to Dong Zhuo." However, in the main text of the Wei section of Records of the Three Kingdoms, in the biography of Dong Zhuo, Yuan Shao, and Liu Zhang, it is only briefly recorded that Dong Zhuo "subsequently killed the Prince and Empress Dowager He," without recording specific details of violence such as falling down the stairs. The novel has undergone artistic processing and embellishment.
