Long term effects of covid-19 pneumonia
Persisting structural lung abnormalities after covid-19 pneumonia seem to be infrequent. Eighty four people who had survived covid-19 pneumonia severe enough to require hospitalisation, but not severe enough to need intubation or mechanical ventilation, were investigated using high resolution computed tomography scanning a year later. Lung abnormalities had completely resolved in 78 of the participants (Radiology doi:10.1148/radiol.220019).
Randomised controlled trials have shown that renal denervation carried out by radiofrequency ablation via a catheter induces a modest fall in blood pressure. A registry study suggests that the procedure leads to a useful reduction in the risk of cardiovascular events. Among 3000 people with hypertension inadequately controlled by …
