A newly developed rapid imaging protocol quickly and cheaply diagnosed heart ailments in patients in Peru, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
In Peru, cardiovascular disease affects 3.2 million (16 percent of the adult population), leading to a significant loss of well-being, estimated at 281,829 Disability Adjusted Life Years.
Current Cardiac Magnetic Resonance Imaging (CMR) usage in high income countries focuses on function, scar (fibrous tissue that replaces normal heart muscle tissue destroyed by injury or disease), perfusion, flow, mapping and angiography and delivers valuable clinical insights leading to targeted and precise treatments. However, these varied techniques make it slow (typically 45 minutes), expensive, complex and potentially out of reach for most people in the developing world.
In this study, researchers developed and tested a rapid CMR protocol using contrast dye that measured cardiac structure, function and scarring. The rapid diagnostics worked with existing infrastructure, took 18 minutes and cost $150 per patient resulting in important changes in patient care.
“Our CMR strategy was three to five times cheaper than current CMR exams in Peru,” said James C. Moon, M.D., study lead author and professor at Barts Heart Centre, St. Bartholomew’s Hospital in London. “It also can be delivered two to three times faster and is easier than conventional CMR.”
Researchers conducted scans on 98 Peruvian patients (average age 52, 60 percent female). Scanning found 26 percent had hypertrophic cardiomyopathy, 22 percent had dilated cardiomyopathy, 15 percent had ischemic cardiomyopathy (when cardiovascular disease or heart attack cause the disease), and uncovered 12 other pathologies including tumors, congenital heart disease, iron overload, amyloid plaques (abnormal protein deposits), genetic syndromes, inflamed vessels, clots and valve disease.
