all vessels of the heart to dilate, is injected into one of the coronary arteries and the amount of blood flow is measured. Next, the drug acetylcholine, which normally causes dilation in the large arteries, is injected and the amount of blood flow is again measured. If either test shows decreased blood flow to the heart muscle, a diagnosis of microvascular disease can be made in women with evidence of insufficient blood flow to the heart muscle and open coronary arteries. Medical therapy is then directed at the specific problem.

Another new test to help researchers better diagnose microvascular coronary disease is cardiac MRI which is available at Cedars-Sinai’s S. Mark Taper Foundation Imaging Center. This test can show poor blood supply to the inside layer of the heart muscle.

Accurately diagnosing microvascular cardiac disease is the first step, Bairey Merz says, but continued research is needed to identify the best course of treatment. “Currently, we have several small studies that indicate the efficacy of different treatments but we don’t have any good, large randomized trials yet to look at how treating this condition may lead to reductions in heart attack, stroke and heart failure. The bottom line is that we need to explore this further, so we can develop therapies that are specific to this type of disease.”
