Remote Photoplethysmography Technology for Blood Pressure and Hemoglobin Level Assessment in the Preoperative Assessment Setting: Algorithm Development Study

Remote Photoplethysmography Technology for Blood Pressure and Hemoglobin Level Assessment in the Preoperative Assessment Setting: Algorithm Development Study

Demographic profile of patients (N=200). a SBP: systolic blood pressure. b DBP: diastolic blood pressure. We defined hypertension according to the European Society of Hypertension (ESH) guidelines [25]. The ESH classifies office BP and defines hypertension grades as shown in Table 2. For our study, we combined Grade 2 and 3 hypertension into a single category. We also defined hypotension as systolic BP (SBP) ≤100 mm Hg and/or diastolic BP (DBP) ≤60 mm Hg [26].

Personalized Smartphone-Enabled Assessment of Blood Pressure and Its Treatment During the SARS-CoV-2 COVID-19 Pandemic in Patients From the CURE-19 Study: Longitudinal Observational Study

Personalized Smartphone-Enabled Assessment of Blood Pressure and Its Treatment During the SARS-CoV-2 COVID-19 Pandemic in Patients From the CURE-19 Study: Longitudinal Observational Study

Changes in self-reported average systolic BP (SBP) and diastolic BP (DBP) during the observational period for group 1 and subgroups within this population are shown in Table 4. No significant changes in average SBP (mean –0.9, SD 10.7 mm Hg; P=.30) or DBP (mean –1.0, SD 7.9 mm Hg; P=.10) were detected between week 1 and week 12. Subgroup analysis by age (≥65 y and .05).

Optimal Systolic Blood Pressure for the Prevention of All-Cause and Cardiovascular Disease Mortality in Older Adults With Hypertension: Nationwide Population-Based Cohort Study

Optimal Systolic Blood Pressure for the Prevention of All-Cause and Cardiovascular Disease Mortality in Older Adults With Hypertension: Nationwide Population-Based Cohort Study

Hypertension is very common in older adults because their systolic blood pressure (SBP) tends to be elevated due to increased stiffness and decreased elasticity in the arteries with aging [5]. Epidemiologic research by the United States National Health and Nutrition Examination Survey has indicated that 76.5% of older adults aged older than or equal to 65 years have hypertension [6].

Real-World Evidence of a Hospital-Linked Digital Health App for the Control of Hypertension and Diabetes Mellitus in South Korea: Nationwide Multicenter Study

Real-World Evidence of a Hospital-Linked Digital Health App for the Control of Hypertension and Diabetes Mellitus in South Korea: Nationwide Multicenter Study

According to the 2020 American College of Cardiology and American Heart Association hypertension guidelines, the BP categories are hypertension (systolic BP [SBP] ≥130 mm Hg or diastolic BP [DBP] ≥80 mm Hg) or not (SBP SBP and DBP were divided, but a pair of SBP and DBP data were used to measure improvement in approaching the objective range. We also measured the FBG and postprandial glucose (PPG) levels.

Effect of the Red Bull Energy Drink on Perfusion-Related Variables in Women Undergoing Microsurgical Breast Reconstruction: Protocol and Analysis Plan for a Prospective, Multicenter Randomized Controlled Trial

Effect of the Red Bull Energy Drink on Perfusion-Related Variables in Women Undergoing Microsurgical Breast Reconstruction: Protocol and Analysis Plan for a Prospective, Multicenter Randomized Controlled Trial

Maintaining a sufficiently high systolic blood pressure is vital for free flap perfusion after microsurgical breast reconstruction. However, many women undergoing microsurgical breast reconstruction have low systolic blood pressure postoperatively. Often, intravenous volume administration or vasopressors are needed to maintain systolic blood pressure above 100 mm Hg.

Blood Pressure Control in Individuals With Hypertension Who Used a Digital, Personalized Nutrition Platform: Longitudinal Study

Blood Pressure Control in Individuals With Hypertension Who Used a Digital, Personalized Nutrition Platform: Longitudinal Study

They found that in the digital intervention groups patients saw an average decrease in blood pressure of 14 mm Hg in systolic blood pressure (SBP) and 5 mm Hg in diastolic blood pressure (DBP) after 90 days compared with those on usual care with a reduction of 4 mm Hg/2 mm Hg [8]. This study displays what is possible at the higher end of blood pressure reductions over 90 days given that this was a partially medication-guided intervention.
