The family of Lloyd Cafe Cardena, the YouTuber who died suddenly last week, has announced his cause of death.

Cardena, 26, died after suffering a heart attack while in the hospital — just days after testing positive for the novel coronavirus (COVID-19), his family wrote on Facebook Monday.

"There are simply no words to express our heartfelt thanks for the prayers and sympathy you have extended to our family during this time of loss," the Cardena family's statement began.

The family explained that the Filipino vlogger first tested positive on September 1 when he was hospitalized for a fever and cough. Three days later, he was discovered unresponsive by hospital staff in the early morning, and doctors said he suffered a heart attack in his sleep.

"Lloyd was confined in the hospital on September 1 due to high fever and dry cough. He was tested for COVID-19 on the same day which the result came out positive on September 3," the statement said.
