Clinical Trial Summary

Acute myocardial injury has been a finding of variable frequency among patients diagnosed with COVID-19. It is now recognized that cTnI levels are strongly associated with increased mortality. The mechanisms underlying the myocardial injury remain unknown, and it is not clear whether they reflect local/systemic inflammatory process and/or cellular ischemia.

Both myocardial ischemia and ventricular dysfunction result in dramatic changes in mitochondrial oxidative metabolism. These changes involve an increase in the rate of cytoplasmic anaerobic glycolysis to compensate for the decrease in mitochondrial adenosine triphosphate (ATP) production. The rest of the mitochondrial oxidative metabolism originates mainly from the β-oxidation of free fatty acids, which occurs at the expense of glucose oxidation.

Trimetazidine is a competitive inhibitor of the enzyme 3-ketoacyl coenzyme A (CoA) long-chain thiolase (3-KAT), the last enzyme involved in the oxidation of fatty acids. Stimulation of glucose oxidation by trimetazidine results in a better coupling between glycolysis and glucose oxidation, with a consequent decrease in lactate production and intracellular acidosis, present in situations of myocardial ischemia or heart failure.

Thus, the PREMIER-COVID-19 study was designed to test the hypothesis that the use of trimetazidine associated with usual therapy in patients admitted with a diagnosis of moderate to severe acute respiratory syndrome by SARS-CoV2 infection reduces the extent of acute myocardial injury assessed by the peak release of ultra-sensitive troponin compared to usual therapy.

Description:

Acute myocardial injury, defined by increased levels of high-sensitivity cardiac troponin I (cTnI), has been a finding of variable frequency among patients diagnosed with COVID-19. This myocardial impairment can occur in the form of acute myocarditis or an injury secondary to the imbalance between oxygen supply and demand (type 2 myocardial infarction). It is now recognized that cTnI levels are strongly associated with increased mortality. The mechanisms underlying the myocardial injury remain unknown, and it is not clear whether they reflect local/systemic inflammatory process and/or cellular ischemia.

Both myocardial ischemia and ventricular dysfunction result in dramatic changes in mitochondrial oxidative metabolism. These changes involve an increase in cytoplasmic anaerobic glycolysis rate to compensate for the decrease in mitochondrial ATP production. Unfortunately, the increase in glycolysis exceeds the subsequent mitochondrial oxidation capacity of pyruvate (glucose oxidation) derived from glycolysis, resulting in the intracellular accumulation of lactate and protons. The protons produced from this decoupling between glycolysis and glucose oxidation contribute to a rupture in ionic homeostasis and myocardial cells, resulting in lower cardiac efficiency. In both the ischemic heart and the insufficient heart, the rest of the mitochondrial oxidative metabolism originates mainly from the β-oxidation of free fatty acids, which occurs at the expense of glucose oxidation.

Trimetazidine is a competitive inhibitor of the enzyme 3-ketoacyl CoA long-chain thiolase (3-KAT), the last enzyme involved in the oxidation of fatty acids. Stimulation of glucose oxidation by trimetazidine results in a better coupling between glycolysis and glucose oxidation, with a consequent decrease in lactate production and intracellular acidosis present in situations of myocardial ischemia or heart failure.

Thus, the PREMIER-COVID-19 study (open and randomized) was designed to test the hypothesis that the use of trimetazidine associated with usual therapy in patients admitted with a diagnosis of moderate to severe acute respiratory syndrome by SARS-CoV2 infection reduces the extent of acute myocardial injury assessed by the peak release of ultra-sensitive troponin compared to usual therapy. Investigators will also assess, as secondary outcomes, the impact on clinical evolution to more severe forms (admission to the intensive care unit or the need for mechanical ventilatory support, length of stay in hospital and in-hospital mortality).
