The Progetto Ipertensione Umbria Monitoraggio Ambulatoriale (PIUMA) Study

The Progetto ipertensione Umbria monitoraggio ambulatoriale (PiUma) Study is a prospective registry of morbidity and mortality in initially untreated patients with essential hypertension whose initial diagnostic evaluation included 24-hour ambulatory blood pressure (aBP) monitoring according to a standardized protocol. The present article summarizes the main results of the PiUma Study. The PiUma Study is conducted in three hospitals in Umbria, italy. after their initial assessment at entry, patients are followed in the outpatient clinic of the referring hospital and in collaboration with their family doctors. Telephone interviews with patients and meetings with family doctors are periodically conducted to ascertain the incidence of major complications of hypertension. The PiUma Study gave us a tremendous opportunity to investigate several aspects related to hypertension: 1) cross-sectional studies focused on the association between clinic and 24-hour aBP and organ damage; 2) longitudinal studies focused on the association between 24-hour aBP and hypertensive organ damage at cardiac level and other levels with the subsequent incidence of major cardiovascular events and mortality; 3) longitudinal studies exploring the prognostic impact of other risk factors in hypertensive patients (i.e. diabetes, dyslipidemia, atrial fibrillation, left ventricular dysfunction, etc.). The PIUMA Study provided the first ever evidence of the prognostic value of: 1) 24-hour ambulatory blood pressure monitoring; and 2) regression of echocardiographic left ventricular hypertrophy in hypertensive patients. The PiUma registry gave us an enormous opportunity for investigating several pathophysiologic, diagnostic and therapeutic aspects related to management of hypertensive patients. Some of our studies have been mentioned in several hypertension guidelines to support some specific statements.
