Dipyrone (Metamizole) can nullify the antiplatelet effect of aspirin in patients with coronary artery disease

摘要

For both the left and right ventricular myocardia, it has been shown that myocardial energy substrate utilization is altered in association with the development of pathological forms of ventricular hypertrophy. In patients with these conditions, myocardial fatty acid utilization decreases while glycolysis increases (1,2). This case clearly demonstrates the altered energy metabolism of failing right ventricular myocardium due to the increased workload in a patient with pulmonary hypertension. This novel imaging sign of pulmonary hypertension may aid detection of this underdiagnosed disorder.
