Does Coronary CT Angiographic and Flow Reserve-Guided Management improve outcomes in patients with stable ischemic heart disease?
Coronary CT angiographic and flow reserve-guided management shows varying composite endpoint risks across different patient groups, with lower MI risk in group 4 vs group 3.
BACKGROUND: ) testing in clinical practice are unknown. OBJECTIVES: testing. METHODS: ≤0.80, OMT, and referral to invasive coronary angiography. Patients were followed for a median of 24 (range 8 to 41) months. RESULTS: >0.80, maximum coronary stenosis was ≥50%. The cumulative incidence proportion (95% confidence interval CI) of the composite endpoint at the end of follow-up was comparable in groups 1 (2.8%; 95% CI: 1.4% to 4.9%) and 2 (3.9%; 95% CI: 2.0% to 6.9%) (p = 0.58) but was higher (when compared with group 1) in groups 3 (9.4%; p = 0.04) and 4 (6.6%; p = 0.08). Risk of myocardial infarction was lower in group 4 (1.3%) than in group 3 (8%; p < 0.001). CONCLUSIONS: testing are needed.
