Abstract

Objective: The results of CT coronary angiography in patients are based on pre-test probability assessment (PTP) at the C1-2 senior staff medical examination department. Subjects and methods: Prospective, cross-sectional description with a convenient sample size of 50 patients with left chest pain, with a priori probability scores calculated and CT coronary angiography based on clinical factors such as the nature of chest pain. typical or not, age, gender and associated cardiovascular risk, calculated on Calculator software by QmXD Pre-test probability of CAD (CAD consortium). Result: In the study group, 10% of patients had Calcium scores ≥400, unable to examine the coronary arteries, 20% of patients had Calcium scores 100-399. Significant coronary artery stenosis ≥50% accounts for 26%. Among 18 patients with ≥50% coronary artery stenosis and 5 patients with Calcium scores > 400 points, 73% of patients had diabetes (p < 0.05), and 61% had hypertension, p < 0.05 and 55% have lipid metabolism disorders with p>0.05. Patients with diabetes had high Calcium scores in the group without diabetes with p < 0.05, the group with hypertension and without hypertension had no difference in Calcium scores with p > 0.05. There is a moderate correlation between Calcium levels and coronary artery stenosis with a prior probability of p < 0.05. Conclusion: Using a priori probability assessment to prescribe CT coronary angiography for chest pain patients visiting the clinic
