Apologies for not making that more clear, I'm exhausted from work and will also refrain from interweb hunting articles to suggest there would be specific evidence for each, but could some examples of more recent cardiac events may have resulted from:

• Covid-19 infection
• Negative response from COVID vaccines
• Aggravation of preexisting condition due to COVID or the COVID vaccine
• Detriment to health related directly or indirectly to harsh lockdown measures in certain regions.

It will be difficult to guage the true nature of harm caused by any, all or none due to the poor perception of trust that the public has in the health services and government behaviour during the pandemic, but if we establish that these are valid possibilities, they are worthy of discussion.
