Blood pressure measurement and the prevalence of postprandial hypotension.

Blood pressure measurement and the prevalence of postprandial hypotension. Clin Invest Med. 2019 Mar 23;42(1):E39-E46 Authors: Madden KM, Feldman B, Meneilly GS Abstract BACKGROUND: Postprandial hypotension (PPH) is a serious condition that has been shown to be an independent risk factor for falls, fractures and death. PURPOSE: The prevalence of this problem in older adults with a past history of falls has shown a wide variability in the literature; the present study seeks to examine how the frequency with which blood pressure is measured impacts the prevalence and severity of PPH. METHODS: Older adults were recruited sequentially from a geriatric medicine falls clinic for meal testing (n=95). All subjects (mean age 77.5±0.7 years, 61±5% female) were fasting prior to each 90 min standardized meal test. A Finometer (Finapres Medical Systems BV) was used to monitor blood pressure. Beat-by-beat systolic (SBP) measures were averaged for 0.5, 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90 min respectively during the meal test. RESULTS: Using the original diagnostic method of checking mean blood pressure every 10 min resulted in a PPH prevalence of 42.1±5.1% in our population, with an overall range from 81.1±4.0% to 11.6±3.3% depending on the frequency of calculating SBP. The maximal observed postprandial decrease in SBP also showed a significant difference with blood pressure measurement frequency (p. PMI...
