Objective: Extensive marketing of devices for self-measurement of blood pressure has created a need for purchasers to be able to satisfy themselves that such devices have been evaluated according to agreed criteria. The Oregon Scientific BPU 330 blood pressure monitor is an electronic device for upper arm measurement. This study assessed the accuracy of the Oregon Scientific BPU 330 blood pressure monitor according to the International Protocol by the Working Group on Blood Pressure Monitoring of the European Society of Hypertension for validation of blood pressure measuring devices.
Method: 52 participants over 30 years of age were studied in the validation. Nine blood pressure measurements were taken alternately with a mercury sphygmomanometer by two observers, and by the supervisor, using the BPU 330 device. A total of 33 participants were selected for the analysis. The validation was divided into two phases. Phase 1 included 15 participants. If the device passed phase 1, 18 more participants were included. The 99 pairs of measurements were compared according to the International Protocol. The device was given a pass/fail recommendation based on its accuracy compared with the mercury standard (within 5, 10, and 15 mmHg), as well as the number met in the ranges specified by the International Protocol.
Results: The mean and standard deviation of the difference between the mean of the observers and the BPU 330 device were 1.7 +/- 4.7 mmHg and 2.8 +/- 3.9 mmHg for systolic blood pressure (SBP) and diastolic blood pressure (DBP), respectively. In phase 1, the device passed with a total of 33, 43, and 44 SBP readings; 38, 44, and 45 DBP readings were within 5, 10, and 15 mmHg, respectively. In phase 2.1, 81, 95, and 96 for SBP, and 83, 95, and 98 for DBP readings fell within the zones of 5, 10, and 15 mmHg, respectively. In phase 2.2, the last phase, 28 participants fell within the zone of two of the three comparisons, lying within 5 mmHg for SBP and 29 participants for DBP. No participants fell within the zone of all three of their comparisons over 5 mmHg apart for both SBP and DBP.
Conclusion: The BPU 330 can be recommended for self-monitoring of blood pressure in the adult population, according to the International Protocol.

Impact of Frailty on Antihypertensive Treatment in Older Adults.
Hypertension

The George Institute for Global Health, Faculty of Medicine, University of New South Wales, Newtown, Australia (L.C., S.Y., N.E., M.W., T.L., Y.G., C.S.A., K.H., X.C., R.P.).
Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.
Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.
Determinants of Racial and Ethnic Differences in Maternal Cardiovascular Health in Early Pregnancy.

Background: Suboptimal cardiovascular health (CVH) in pregnancy is associated with adverse maternal and offspring outcomes. To guide public health efforts to reduce disparities in maternal CVH, we determined the contribution of individual- and neighborhood-level factors to racial and ethnic differences in early pregnancy CVH.
Methods: We included nulliparous individuals with singleton pregnancies who self-identified as Hispanic, non-Hispanic Black (NHB), or non-Hispanic White (NHW) and participated in the nuMoM2b cohort study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be).
Early Versus Delayed Antihypertensive Treatment After Acute Ischemic Stroke by Hypertension History.

Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, China. (X.X., X.L., Y.P., Yufei Wei, Y.J., M.W., J.J., X.M., Yilong Wang, Yongjun Wang, L.L.).
Background: We performed a prespecified subgroup analysis of the CATIS-2 trial (China Antihypertensive Trial in Acute Ischemic Stroke II) to compare the effect of early versus delayed antihypertensive treatment on death and disability in patients with and without medical history of hypertension.
Methods: CATIS-2 is a multicenter randomized clinical trial conducted in 106 hospitals in China. The trial randomized 4810 patients with acute ischemic stroke within 24 to 48 hours of symptom onset and elevated systolic blood pressure between 140 and <220 mm Hg to receive antihypertensive treatment immediately after randomization or to discontinue antihypertensive medications for 7 days and then receive treatment on day 8.

Objective: To describe the characteristics of patients diagnosed with acute heart failure (AHF) in emergency departments (EDs) who develop cardiogenic shock (CS) not associated with ST-segment elevation acute coronary syndrome (STACS).
Methods: Information for patients diagnosed with AHF in 23 Spanish EDs and registered between 2009 and 2019 were included for analysis if the patients developed symptoms consistent with CS. We described baseline clinical characteristics related to cardiac decompensation and CS, as well as 30-day mortality.

Pregnancy issues such as gestational hypertension, preeclampsia, and gestational diabetes mellitus (GDM) are significant contributors to long-term cardiovascular diseases (CVDs) in women. Recent research has proved the impact of exercise on improving cardiovascular outcomes, particularly in women with pregnancy-related disorders. This review explores the outcomes of various exercise interventions on cardiovascular health in pregnant women.
