2. Fig 1
Angina class before TMR and at 1 month, 3 months, 6 months, and 12 months following TMR. Canadian Cardiovascular Angina classification based upon direct questioning of patients at the timepoints indicated. The data are represented as mean ± standard deviation with the base line represented as the solid square and 1 month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints (TMR = transmyocardial laser revascularization.)

Sublingual nitroglycerin intake per week before therapy and at 1 month, 3 months, 6 months, and 12 months following TMR. The data are represented as mean ± standard deviation with the base line represented as the solid square and 1 month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints. (TMR = transmyocardial laser revascularization.)

Exercise tolerance testing–exercise duration before therapy and at 1 month, 3 months, 6 months, and 12 months following TMR. The data are represented as mean ± standard deviation with the base line represented as the solid square and I month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints. (TMR = transmyocardial laser revascularization.)

5. Fig 4
Exercise tolerance testing ST/HR slope before therapy and at 1 month, 3 months, 6 months, and 12 months following TMR. ST/HR slope was determined from peak exercise regression of ST depression expressed as a positive value referenced to heart rate. The data are represented as means ± standard deviation with the base line represented as the solid square and 1 month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints. (ST/HR = ST segment/heart rate slope; TMR = transmyocardial laser revascularization.)

6. Fig 5
Myocardial viability before therapy and at 3 months, 6 months, and 12 months following TMR. Myocardial viability was assessed by 24-hour redistribution thallium nuclear medicine scan at the timepoints indicated. The data are represented as means ± standard deviation with the base line represented as the solid square and 1 month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints. (TMR = transmyocardial laser revascularization.)
