For how long can we rely on the CT coronary angio results? My mom is 65, diabetic, and had one done in February 2020it all looked pretty normal back then, no plaque in the main artery and a calcium score of zero. Her recent ECG also came back normal and she's not having any symptoms, but we've found that she has mild pulmonary hypertension with a systolic pressure of 34 mmHg on a 2D echo. She's not taking any blood thinners right now. Do you think we should consider repeating the CT angio?

CT coronary angiography is a non-invasive imaging test that can provide detailed information about the coronary arteries. In your mother's case, since her CT angio done in Feb 2020 showed a fairly normal result with no plaque in the main artery and a calcium score of zero, it indicates a low risk of significant coronary artery disease at that time. Given that the recent ECG is normal and your mother has no complaints, the decision to repeat the CT angio should be based on her current symptoms, risk factors, and overall clinical condition. Mild pulmonary hypertension as seen in the 2D echo with a systolic pressure of 34 mmHg may not necessarily warrant a repeat CT angio unless there are new symptoms or concerns regarding her cardiac health. It is important to continue monitoring her condition regularly with follow-up visits to her healthcare provider, who can assess the need for any further investigations or adjustments to her treatment plan.
