I am a strong advocate for early detection and aggressive risk management for patients with undiagnosed coronary artery disease. Acute MI and sudden death are still and unfortunate first presentation for patients with previously unknown CAD.Traditional risk factor assessment and indications for aggressive lipid management often underestimate the extent of disease. Asymptomatic CAD patients, and patients with undiagnosed CAD and atypical CP who have had a normal stress stress represent the largest group of missed opportunities in the treatment of heart disease. The finding of a positive coronary calcium score demonstrates the presence of inflammatory atherosclerosis, and safely and quickly finds those patients who deserve aggressive treatment and surveilence for the future risk of adverse cardiac events. In appropriate low to intermediate symptomatic patients, cardiac CT angiography may be the best test to safely and accurately exclude or identify significant CAD. CTA is particularly useful in the ER to evaluate patients who have unknown source of CP and negative EKG and biomarkers. We provide 24/7 Calcium scoring and CTA in our ED and safely discharge 75% of our chest pain patients within 6 hours when CAD is excluded as a cause of their symptoms. Patient who have significant CAD are quickly identified for treatment avoiding inappropriate discharges. As an interventional cardiologist, CT imaging of the heart has become an important and invaluable part of my clinical practice in Cardiology.
