Patients with AF and newly redefined hypertension according to the 2017 ACC/AHA guideline were at higher risk of major cardiovascular events, suggesting that the new BP threshold is beneficial for timely diagnosis and intervention. BP of 120 to 129/<80 mm Hg was the optimal BP treatment target for patients with AF undergoing hypertension treatment.

Purpose Exposure to particulate matter (PM) is a well-known risk factor in the triggering and exacerbation of allergic airway disease. Indoor environments, where people spend most of their time, are of utmost importance. To assess the effects of air purifiers [equipped with high-efficiency particulate air (HEPA) filters] on allergic rhinitis (AR) in adult patients, we performed a multicenter, randomized, double-blind, and placebo-controlled study. Materials and Methods Patients with house dust mite (HDM)-induced AR were randomly assigned to either active or mockup (placebo) air-purification groups. Two air purifiers (placed in living room and bedroom) were operated for 6 weeks in each home environment. The primary study endpoint was to achieve improvement in AR symptoms and medication scores. Secondary endpoints were to achieve improvement in the quality of life (QoL) and visual analog scale (VAS) scores, as well as in the indoor (bedroom and living room) concentrations of PM 2.5 and PM 10 . Results After 6 weeks of air purifier use, medication scores improved significantly in the active (vs. placebo) group, although subjective measures (symptoms, VAS, and QoL scores) did not differ. Bedroom PM 2.5 concentrations initially exceeded living room or outdoor levels, but declined (by up to 51.8%) following active purifier operation. Concentrations of PM 2.5 in living room and PM 10 in bedroom and living room were also significantly reduced through active purification. Conclusion The use of air purifiers with HEPA filters significantly reduced medication requirements for patients with HDM-induced AR and significantly lowered indoor PM 2.5 concentrations, regardless of room placement. Active intervention to reduce household air pollutants may help improve allergic airway disease ( clinicaltrials.gov NCT03313453 ).
