An analysis of diagnostic test results from the Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) trial — in which patients with stable chest pain were randomized to either anatomic or functional testing as an initial diagnostic strategy — showed that the presence and extent of coronary artery disease detected by CT angiography better predicted the risk for future cardiac events than did measures of exercise tolerance or restricted blood flow to the heart muscle.

The resulting rhythmic signals produced by this transfer of cations are what support the synchronous contraction of our heart muscles and neuronal firing in parts of the brain, like the thalamus, which helps regulate our sleep - wake cycle, or circadian rhythm.

A heart attack occurs when blood flow to an area of the heart is blocked by a narrowed or completely obstructed coronary artery, resulting in damage of heart muscle.
