Key result
Cardiac catheterization demonstrated a diagnostic yield of only 37.6% among nearly 400,000 patients evaluated for suspected coronary artery disease.
Why the study?
What is the diagnostic yield of cardiac catheterisation in patients with suspected coronary artery disease?
What is the diagnostic yield of cardiac catheterisation in patients with suspected coronary artery disease?
The low diagnostic yield of cardiac catheterisation in suspected CAD highlights the need for better risk stratification strategies.
Supports refined pretest selection before catheterization; leaves open prospective validation of improved risk stratification.
The widespread application of specialist clinics for early evaluation of patients with chest pain has focused atten-tion on the effectiveness of diagnostic testing. In a stu-dy of nearly 400,000 patients with suspected coronary artery disease, the diagnostic yield of cardiac cathete-risation was only 37.6%, leading to calls for better stra-tegies for risk stratification.
