There is no evidence to suggest that a Sinovac Covid vaccination triggered acute heart and lung conditions which led to the death of a 63-year-old man, a doctor told the coroner's court.
Timble Li Yu-kun received the first dose of Sinovac's
Covid-19
vaccine at Kwun Chung community vaccination center on February 26. He felt unwell two days later and headed to Queen Elizabeth Hospital, where he died on the same day.
Dr Cheuk Wah, from Queen Elizabeth Hospital's Department of Pathology, testified in front of two men and three women on Wednesday as the coroner's court handles its first case of post-vaccination death.
Citing an autopsy report, Cheuk said Li died at 6am on February 28 of acute pulmonary edema, which was triggered by acute myocardial infarction.
He said the heart condition was detected two to three weeks before Li died. Hyperemia of his lungs made it difficult for the patient to breathe.
Cheuk said Li did not show any symptoms of allergy, and there is no evidence that vaccination causes myocardial infarction, he added.
Alvina Lo from Yau Ma Tei Jockey Club General Out-patient Clinic said Li started accepting treatment in June last year. He was diagnosed with diabetes, hypertension and high cholesterol.
In his last follow up on February 3 this year, he was diagnosed with angina but did not demonstrate signs of acute heart diseases. He was recommended to visit a cardiologist and quit smoking – he smoked three packs a day – but the latter advice was snubbed by the patient.
Lo said Li's diabetes fluctuated as he did not take medication in accordance to the prescribed dosage. While the man faced risks of heart diseases, his condition was not considered dangerous because his angina was stable.
Doctor Lam Ka-chun from Queen Elizabeth Hospital said Li attended the accident and emergency department shortly after 1am on February 28.
Li reported shortness of breath, coughs and chest discomfort, while his blood pressure and heart rate were higher than average. Chest scans of his lungs showed that he could be suffering from bronchitis and acute pulmonary edema – a condition caused by excess fluid in the lungs.
Lam said he prescribed medication to Li and immediately arranged to admit him to the medical ward, but he did not send him to the intensive care unit because Li did not seem to be suffering from serious allergies or a heart attack.
