Figure 1. Angiographic findings of subjects with suspected CAD (cohort 1).

Figure 1

Arrangement in age strata beginning with 18–45 years followed by 10-years intervals for men and women, separately. Coronary angiograms were interpreted as no CAD when angiographically normal coronary arteries were found, the presence of wall irregularities (WI) was interpreted as intermediate coronary atherosclerosis (CAD<50%). Stenoses with ≥50% luminal reduction were rated as obstructive CAD and assessed as 1-, 2- or 3-vessel disease (1VD, 2VD, 3VD). For comparison, representative results of the American College of Cardiology National Data Registry (NCDR CathPCI Reg.) are shown including patients with elective coronary angiography for suspected coronary artery disease [21].
