1 Use and Interpretation of Home Blood Pressure Monitoring BLOOD PRESSURE in year 2015 PARAMETERS TODAY Gianfranco Parati University of Milano-Bicocca & Ospedale S.Luca, IRCCS, Istituto Auxologico Italiano Milan, Italy

2 OFFICE OR OUT-OF-OFFICE BP? The ESH current position: Need of out-of-office BP

3 2013 ESH/ESC Hypertension Guidelines Blood pressure management, history, and physical examination Recommendations Class Level It is recommended that all hypertensive patients undergo palpation of the pulse at rest to determine heart rate and to search for arrhythmias, especially atrial fibrillation. I B Out-of-office BP should be considered to confirm the diagnosis of hypertension, identify the type of hypertension, detect hypotensive episodes, and maximize prediction of CV risk. IIa B For out-of-office BP measurements, ABPM or HBPM may be considered depending on indication, availability, ease, cost of use and, if appropriate, patient preference IIb C
