Many of us will have sat in a GP’s office and been quizzed about our health history. We accept that our risk of heart disease or stroke is framed by factors such as whether we’ve smoked, what we eat and drink, and how much we exercise.
Now a report published in Nature Medicine and led by researchers from Washington University suggests whether we’ve had COVID – even a mild case – could be added to that checklist. Expert authors Clare Arnott, Jamie Cham and Bruce Neal from the George Institute for Global Health and University of Sydney note the large-scale study highlights our limited understanding of the full consequences of COVID infection.
The big concern is that medium- to long-term harm to the body’s blood vessel network (the vascular system) appear more common than previously thought. Between 30 days and a year after recovery from COVID, survivors studied were 52% more likely to have a stroke, 63% more likely to have a heart attack, and 72% more likely to develop heart failure. When scaled to 600 million COVID infections worldwide, the implications are enormous.
These risks could drive a new pandemic of heart disease over coming years. They should serve as yet another wake-up call – that COVID can impact our health long after we’ve recovered from the initial illness.
