Supports PEF for elderly mortality risk stratification; extends prior observational data but leaves causality and practice change open.
Does lower peak expiratory flow rate predict increased mortality and ischaemic heart disease in elderly individuals?
Lower peak expiratory flow rate is an independent predictor of all-cause and ischemic heart disease mortality in the elderly, highlighting the importance of risk factor management in patients with airways disease.
