Fig. 7From: Clinical outcomes meta-analysis: measuring subendocardial perfusion and efficacy of transmyocardial laser revascularization with nuclear imaging a Ho:YAG and CO2: 30 day survival. There was an increase in the survival rate of patients in the treatment group as compared to the control group (p = 0.15). b Ho:YAG and CO2: 12 month survival. Patients in the laser treatment group had a higher rate of survival as compared to those in the control group (p = 0.65). c Ho:YAG and CO2: angina reduction at 12 months. A statistical significance in angina reduction of two or more CCS classes was determined between the laser therapy group and the control group (p = 0.002)Back to article page
