Background: Self-measured blood pressure (BP) monitoring, has been proposed as a means of improving BP control. Lifestyle modifications are indicated in hypertension at any stage. AHA’s Life Simple 7 provides a straightforward call-to-action. mHealth services (mHs) may provide additional tools to effective BP control. Aim: We tested the reproducibility of the initial results of a mHs for remote BP monitoring and lifestyle counseling. The mHs in study is a cloud -based BP -recording, -interpretation and -trend evaluation service (BT) coupled with personalized lifestyle-change programs (LC). Initial results showed a significant reduction of BP at the end of the LC program. BT collects BPs, and after consistency-checks, feeds a proprietary CE-certified medical device algorithm to provide actual BP interpretation and BP trend assessment. Through a separate proprietary algorithm, LC provides a 3-month personalized lifestyle modification program for BP reduction, built on the AHA’s Life Simple 7 , after collecting detailed clinical and lifestyle data. BP changes were evaluated comparing BPs recorded at the beginning and at 3 months in both groups. We studied 2601 subjects (50±14 years old) that voluntarily and unsolicited joined LC+BT or BT-only, from June 2016 to April 2017, via App or website. Results: During the study period a total 60044 BP values were collected, subjects with discontinuous BP measurements were excluded from evaluation. We hence analyzed the data of 575 LC+BT subjects and 1653 BT-only subjects. We observed a significant BP reduction in LC+BT subjects at the end of the program for both systolic and diastolic BPs: 4.7±1.2 and 3.3±0.8 (mean + SEM, mmHg), p<0.0001, respectively. In BT-only subjects the reduction of BP values at 3-months was 2.5 ±0.9 and 1.7±1.0, p<0.001, respectively. The subjects of the LC+BT group with > 3 systolic BPs above normal values in the first 10 days, experienced a greater BP reduction: 7.9±1.4 and 4.2±1.1, p<0.0001, respectively. Conclusions: The data confirm that this mHealth service provides a strong and effective adjunctive tool for BP reduction. These results support the value of the combination of algorithm based remote BP monitoring and a personalized implementation of AHA’s Life Simple 7 recommendations.
