Heart rate recovery after orthostatic challenge and cardiopulmonary exercise testing in older individuals: prospective multicentre observational cohort study.

Background: Impaired vagal function in older individuals, quantified by the 'gold standard' delayed heart rate recovery after maximal exercise (HRR), is an independent predictor of cardiorespiratory capacity and mortality (particularly when HRR ≤12 beats min). Heart rate also often declines after orthostatic challenge (HRR), but the mechanism remains unclear. We tested whether HRR reflects similar vagal autonomic characteristics as HRR.

Preoperative and postoperative optimisation of patients undergoing thyroid surgery: a multicentre quality improvement project at Barts Health NHS Trust.

Hypocalcaemia following thyroid surgery can occur in up to 38% of patients. With over 7100 thyroid surgeries performed in 2018 in the UK, this is a common postoperative complication. Undertreated hypocalcaemia can result in cardiac arrhythmias and death.

Making the case for spirometry as part of the perioperative multidisciplinary team assessment.

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality and is significantly underdiagnosed in the community. Respiratory impairment is a key risk factor for perioperative morbidity and mortality. The National Institute for Health and Care Excellence (NICE) does not recommend routine spirometry before major surgery.
