GLP1R and dilated cardiomyopathy: Similarly, continuous infusion of both native GLP-1(7–36)amide and GLP-1(9–36) improved systolic/diastolic function and myocardial metabolism in dogs with rapid pacing-induced dilated cardiomyopathy, although GLP-1(9–36) failed to increase cardiac output during regional myocardial ischaemia in pigs [12, 33].
