ObjectiveA significant proportion (85%) of low-risk non-ST-elevation acute coronary syndrome (NSTE-ACS) patients do not receive objective confirmation of ischemia by stress echocardiography (SE), yet remain a healthcare burden due to lower long-term survival and overuse of medical services.

PCI is commonly used to open blocked arteries to treat significant myocardial ischemia , which occurs when the heart muscle does not get enough oxygenated blood. To test this strategy, researchers enrolled 1,606 patients treated for coronary artery disease at 15 centers in four countries.

Traditional methods of non-invasive ischemia testing (stress EKG , stress echo, SPECT , PET , direct-to-cath) can result in false negatives 20-30 percent of the time, which can lead to undetected disease, and false positives over 50 percent of the time, which can lead to unnecessary invasive procedures.

Heart Valve Disease If one or more heart valves are not functioning correctly, it can cause blood to flow backward, putting extra pressure on the heart, which may cause it to expand to compensate for the inefficiency. This may result in ischemia (lack of oxygen to the heart muscle), causing parts of the heart to weaken and enlarge.

CT coronary angiography, in addition to a CT CAC, is arguably the best test for estimating whether someone has evidence of coronary artery disease and what that means for their near-term risk of a heart attack. This article is part 2 of a series on cardiac CT. I would say yes. For very good reason. And it matters.

For example, if a coronary artery becomes blocked due to plaque buildup (a condition known as coronary artery disease), the heart muscle may not receive enough oxygen, leading to chest pain (angina) or, in more severe cases, a heart attack. CAD is one of the leading causes of heart attacks.
