You should consult your cardiologist because it depends on your clinical and/or laboratory scenario:
For patients with chest pain with high probability for acute coronary syndrome, invasive imaging with conventional angiography/cardiac catherization may be appropriate.
For patients with chest pain with low to intermediate probability for acute coronary syndrome, noninvasive imaging with cardiac stress testing may be appropriate. Common modalities include ultrasound (echocardiography), nuclear medicine (myocardial perfusion imaging), and CT (CTA coronary arteries).
