HARVEST Trial

Keywords: repeated measures


Description

HARVEST (Hypertension and Ambulatory Recording Venetia Study) is a trial designed to assess whether ambulatory monitoring adds something to office (clinical) blood pressure in predicting the development of fixed hypertension and of cardiovascular complications in patients with borderline to mild hypertension. Ambulatory monitoring refers to the measuring of home blood pressure by an annotated device that the subject wears for 24 hours. The data give information on 1100 subjects compiled by Dr Paolo Palatini, Professor of Clinical Medicine at the University of Padua, Italy.

Patients were eligible for the study if they satisfied the following criteria:

The subjects were followed for 5 years. Baseline examinations, including ECG and echocardiography, were repeated at the end of the study or upon development of hypertension, defined as BP persistently 100 mm Hg or greater or a systolic BP of 160 mm Hg or greater. Ambulatory monitoring was repeated 3 months and 5 years after the baseline evaluation.

The symbol C or A after the name of a variable means:
C = clinical examination; A = ambulatory (home monitoring)

The last symbol of a variable name may be B, 3, 5 or E:
B = baseline examination
3 = 3-month examination
5 = 5-year examination
E = endpoint examination


Variable Description

Smoke Smoking status at baseline examination:
0 = non-smoking,
1 = 1-5 cigarettes per day,
2 = 6-10 cigarettes per day,
3 = 11-20 cigarettes per day.
Sport Sport activity at baseline examination:
0 = only sedentary,
1 = light activity (walking),
2 = sports non-competitive,
3 = sports competitiv.
SBP Systolic blood pressure
DBP Diastolic blood pressure
HR Heart rate
Age Age in years
BMI Body mass index: 100 * weight (kg) / height (m)2
EndPoint Endpoint status at the time the file was created:
1 = blood pressure level hypertensive
0 = blood pressure level not hypertensive
Time Time in months from baseline examination to the date of endpoint or to May 30, 1999, whichever was earlier
Male Gender:
1 = male
0 = female

Missing values are indicated by "."
