Our non-invasive methods for energy metabolism assessment using phosphorus MR spectrscopy are ideal for treatment testing in patients, where cardaic or skeletal muscle metabolism is impaired.<\/p>\n

Hence in collaboration with Boeringer Ingelheim, we have tested the potential mecahnism of effect of their new sodium-glucose co-transporter inhibitor drug (empagliflozin), which is one of the new superdrugs in treatment of hart failure. In total, we have recruited 72 patients with heart failure and measured their cardiac energetics pre and post 3 months of empagliflozin or placebo intake. And while we were not ablo to prove the effect of empagliflozin on cardiac energetics, we showed that patients taking empagliflozin felat better than those on placebo, proving the efficcacy of this drug.<\/p>\n

Similarly, together with Axcella Therapeutics, we have investigated the efficacy of their new drug AXA1125 for improvement of muslce energy metabolism in patients suffering from long-COVID. In a\u00a0group of 40 patients, we demonstrated that in those where the drug improved symptoms, the muscle oxidative metabolism also improved.<\/p>\n

PCr\/ATP remained unchanged in both HFrEF (A) and HFpEF (B) after 12 weeks of empagliflozin treatment at rest (top row) and during dobutamine stress (bottom row), with 65% of age-maximum heart rate (ie, 220-age).<\/em><\/p>\n
