Figure 1 Graph of perioperative mortality rates in patients with and without unstable angina preoperatively. The rate in patients with unstable angina was 50% versus 3% in those without unstable angina. Using one-way analysis of variance, unstable angina was the only variable of those studied that was associated with an increased risk of perioperative mortality (p = 0.005). Solid bar = unstable angina; open bar = stable angina.

Figure 2 Graph of perioperative adverse cardiac and noncardiac event rates in the first 15 (solid bars) versus the final 19 (open bars) patients undergoing transmyocardial laser revascularization at our institution. Patients among the initial 15 treated had significantly higher rates of both cardiac (p = 0.005) and noncardiac (p < 0.001) morbidity.

Figure 3 Graph of perioperative adverse cardiac and noncardiac event rates in patients receiving (open bars) and not receiving (solid bars) a furosemide infusion beginning in the immediate postoperative period. Patients not receiving a furosemide infusion had significantly higher rates of both cardiac (p = 0.04) and noncardiac (p = 0.02) morbidity.
