CONTRAST enrolled 763 subjects and measured aortic pressure (Pa), distal coronary pressure (Pd), and electrocardiogram (ECG) signals continuously during several physiologic conditions (rest, injection of intracoronary contrast, injection of intracoronary adenosine, infusion of intravenous adenosine, and sensor pullback to the guiding catheter). See the manuscript for details, especially Figure 2 for a visual example. Recordings were made using the St Jude Medical QUANTIEN system with an Aeris or Certus PressureWire.

Each anonymous data file follows the naming pattern CON###[n].csv, where ### are numbers from 001 to 763 denoting the unique subjects but in random order. For a small minority of subjects (26 total) the recording was split over multiple files, ordered temporally using suffix letters a and b (and one subject has three files, ordered a, b, and c). The comma-separated variables (CSV) text files contain a single header line followed by one or more data lines. Each row represents a 100 Hz sample frequency, hence 10 millisecond time intervals. Every data entry contains a signed integer. For pressures, divide by 10 to obtain units of mmHg; ECG signals have no units but equal 1 for missing data in a small minority.

Due to the large number of subjects, CONTRAST.tgz used tar and gzip to compress all 790 CON###[n].csv files together.
