- Other than left ventricular ejection fraction (LVEF), no significant difference was seen between the groups in factors previously reported to affect adenosine response
- Data given as mean ± standard deviation or n (%)
- Group 1—Patients with coronary disease and left ventricular ejection fraction (LVEF) > 40%. Group 2—Mild to moderate heart failure, LVEF ≥ 40% and no evidence of coronary artery disease. Group 3—moderate to severe heart failure, LVEF < 40% and no evidence of coronary artery disease
