Cardiorespiratory collapse signifies a sudden cessation of heart and lung function, leading to the failure of breathing and circulation. Massive pulmonary thromboembolism (PTE) is when a large blood clot obstructs the lung arteries, preventing proper blood flow and causing sudden collapse.

What is Cardiorespiratory collapse and PTE?

Cardiorespiratory collapse means the heart and lungs have stopped functioning suddenly. In simple terms, the person’s breathing and circulation failed, leading to death.

Massive pulmonary thromboembolism (PTE) is the main cause mentioned. It happens when a large blood clot blocks the arteries in the lungs. A clot usually forms in the legs (deep vein thrombosis) or elsewhere in the body

It then travels to the lungs, and if it blocks a major vessel, blood cannot reach the lungs properly. This causes sudden breathlessness, low oxygen, collapse, and cardiac arrest

A “massive” PTE means the blockage was large enough to be rapidly fatal.

Some youths who were seen with the body at the civil hospital, nearly a kilometre from Prateek's residence, said they rushed Prateek to the hospital around 5.10 am, and he was officially declared dead around 6 am.

Civil Hospital director Dr GC Gupta told PTI that Prateek was brought dead to the facility.

"We ran the necessary SOPs, and after confirmation, we informed senior officials and police," Dr Gupta said.

The doctor told PTI that around 5.30 am, a driver from Prateek's residence came to the hospital seeking help. An Emergency Medical Officer visited his residence and brought him to the hospital, he said.

Asked about reports making rounds that Prateek was found unconscious inside the kitchen by EMO, Dr Gupta said, "Various things are being said, but I can't say anything for sure."

Prateek's wife was apparently not at home at the time and out of state. Scores of supporters of the Yadav family gathered outside Prateek's Vikramaditya Marg home.

Prateek was also known to be an animal lover and supported many animal shelters.

On January 19 this year, Prateek openly accused his wife of ruining his family ties and said he would seek a divorce from her at the earliest. In a lengthy post on his Instagram account (iamprateekyadav), the late politician's son described Aparna Yadav as a "family destroyer" and accused her of being "self-centred" and "driven by fame and influence."

However, on January 28, he announced reconciliation with his wife.

In a video he posted on Instagram, Prateek said, "On January 19, I had a serious dispute with my wife Aparna, following which I made two posts on social media. However, the matter has now been resolved mutually after discussions, and there is no longer any dispute between us."

He also posted a caption in the video: "Haters, go to hell."

In another post, he shared a video with Aparna.
