Hypertrophic Cardiomyopathy (HCM)

Hypertrophic cardiomyopathy (HCM) causes the walls of the left ventricle to become thicker than normal. This can cause a blockage to blood flow in some patient and is classified as obstructive HCM. This is the most common form of HCM where the septum between the ventricles can reduce the blood flow into the aorta. Nonobstructive HCM is where the heart muscle is thickened but does not block blood flow. The thickened walls stiffen and reduce the amount of blood the heart can pump. HCM is usually caused by an inherited genetic variant (familial hypertrophic cardiomyopathy) and can be detected with genetic testing and diagnosed with medical imaging. It is considered widely underdiagnosed. HCM can lead to heart failure and sudden cardiac arrest. Treatments include drug therapy, septal myectomy and alcohol septal ablation.

The projected number of acquired cardiomyopathy cases are expected to greatly outpace the number of new familial cardiomyopathy cases by 2031 in the U.S., driven mainly by poor lifestyles. This is expected to have a big impact on healthcare.

U.S. expected to see large rise in cardiomyopathy cases over next decade

“Even if we compensate for the differences in population size, the U.S. is still miles ahead when it comes to total cardiomyopathy cases," explained Walter Gabriel, MPH, an epidemiologist and analyst on the report.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
