RESUMO
Type 2 diabetes mellitus (T2DM) is associated with premature atherosclerosis and arterial stiffening due to the accumulation of advanced glycation end-products in vessel walls. Green tea polyphenols are considered cardio-protective substances. In this randomised double-blind placebo-controlled trial (NCT02627898), we evaluated the effect of Green tea extract on arterial stiffness parameters, lipids, body composition and sRAGE levels. Twenty normotensive patients with T2DM treated with the standard therapy and statins, mean age 53.2 ± 9.4 years and mean BMI 30.1 ± 4.5 kg/m2, were randomised to receive a daily dose of 400 mg of green tea extract (polyphenols ≥90%, EGCG ≥45%) or placebo for 12 weeks. Compared to placebo, administration of green tea extract decreased central augmentation index (-3.05 ± 10.8% vs. 6.7 ± 0.1%, p = .04). These findings suggest that green tea extract could be used as an adjunct to the standard therapy to improve arterial stiffness in T2DM.

OBJECTIVE: The aim of this study was to determine the accuracy of the Omron HEM-7320-LA with Intelli Wrap technology cuff HEM-FL1 for self-measurement and clinic blood pressure (BP) measurement according to the European Society of Hypertension International Protocol revision 2010. PARTICIPANTS AND METHODS: The evaluation was performed in 39 individuals. The mean age of the participants was 47.9±14 years; systolic BP was 145.2±24.3 mmHg (range: 97-190), diastolic BP was 90.9±12.9 mmHg (range: 68-120), and arm circumference was 30.8±4 cm (range: 25-38.5). RESULTS: The device successfully fulfilled the established criteria of the validation protocol. The device overestimated systolic BP by 0.6±5.7 mmHg and diastolic BP by 2.2±5.1 mmHg. The specially designed cuff HEM-FL1 to cover a broad range of arm circumferences and self-placement fulfilled the requirements of the International Protocol.
