研究目的
Investigating the therapeutic effects of cardiac computed tomography angiography (CTA) and CT-derived fractional flow reserve (FFR) on patients with chest pain and suspected coronary artery disease.
研究成果
Cardiac CT is a valuable tool for diagnosing coronary artery disease, especially when combined with functional assessments like CT-derived fractional flow reserve or myocardial perfusion imaging. However, its use should be tailored to harness the strengths and limitations of each technique to answer specific clinical questions.
研究不足
Suboptimal specificity of CT angiography, potential for increased cardiac catheterizations and revascularizations, lack of clear superiority over other noninvasive functional tests.
1：Experimental Design and Method Selection:
Randomized controlled trials comparing CT angiography with and without myocardial perfusion imaging (CTP) and CT-derived fractional flow reserve (FFR) in patients with suspected coronary artery disease.
2：Sample Selection and Data Sources:
Patients with chest pain and suspected coronary artery disease.
3：List of Experimental Equipment and Materials:
Computed tomography angiography equipment, myocardial perfusion imaging equipment.
4：Experimental Procedures and Operational Workflow:
Patients underwent CT angiography, with some receiving additional myocardial perfusion imaging or CT-derived fractional flow reserve.
5：Data Analysis Methods:
Comparison of diagnostic performance, revascularization rates, and clinical outcomes between different testing strategies.
