Figure 2. Angina and Heart-Failure Symptoms at Baseline and at the Last Follow-up Visit.

Figure 2

Symptoms of angina, classified according to criteria of the Canadian Cardiovascular Society (CCS), and symptoms of heart failure, classified according to criteria of the New York Heart Association (NYHA), improved significantly for the 499 patients who underwent coronary-artery bypass grafting (CABG) alone and for the 501 patients who under-went CABG with surgical ventricular reconstruction (SVR) between baseline and the latest follow-up visit, at a median of 48 months. Angina symptoms improved by an average of 1.7 classes in both cohorts (P = 0.84) (Panel A). Heart-failure symptoms improved by an average of one class in both cohorts (P = 0.70) (Panel B).
