Figure 1 NYHA/CCS Score (Subjective) and Treadmill Exercise Time (Objective) Parameters During Follow-Up After ASA

There was marked early improvement of heart failure symptoms (New York Heart Association [NYHA] score) and angina (Canadian Cardiovascular Society [CCS] score) at 3 months, and this improvement persisted during follow-up. This also correlated with improvement in treadmill exercise time. ASA = alcohol septal ablation; BL = baseline.
