The DIGAMI study compared “conventional” anti-diabetic therapy to intensive insulin therapy consisting of acute insulin infusion during the early hours of MI and. On the basis of these findings, the Diabetes Mellitus Insulin Glucose Infusion in Acute Myocardial Infarction (DIGAMI 1) trial was started. View fulltext. DIGAMI 1 was a prospective, randomised, open-label trial with blinded endpoint evaluation (PROBE) done at coronary care units in

There is also a digzmi that in the course of implementing prolonged intensive insulin therapy, patients had increased follow-up appointments and continuing care visits teial their outpatient physicians.

Although there was an overall reduction in adverse outcomes in patients receiving the intensive insulin regimen, it is unclear which component the IV insulin infusion or the intensive chronic therapy was responsible.

Although improvements have been made in the treatment of cardiac disease, diabetic patients with acute MI continue to have a poor prognosis. Glucose does not require oxygen when metabolized glycolysisbut this process, as described above, is impaired by the hormonal changes that take place during MI.

This increase in mortality is shown during both initial hospitalization and long-term follow up. Decreased insulin sensitivity causes impaired glucose utilization and increased free fatty acid turnover in cardiac muscle. Metabolism of free fatty acids, glucose, and catacholamines in acute myocardial infarction: J Am Coll Cardiol Some credit the overall frial to widespread use of medications, such as beta-blockers, aspirin, and thrombolytics.


Diabetes may be associated with severe coronary artery disease, systolic left ventricular ditami, autonomic neuropathy, and larger infarct size.

Digzmi, concomitant therapy was similar between both groups of the study. Instead, it showed a decreased mortality in diabetic patients admitted with MIs when given an intensive insulin regimen extending from admission up to 1 year. The effect of intensive treatment of diabetes on the development and progression of long-term complications in insulin-dependent diabetes mellitus.

These processes not only leave these diabetic patients at higher risk of death when having an acute MI, but also increase their risk of recurrent cardiac events and other long-term complications.


The Diabetes Control and Complications Trial DCCT revealed that intensive insulin therapy delayed the onset and slowed the progression of microangiopathies nephropathy, neuropathy, and retinopathy. The purpose of the DIGAMI study was to evaluate whether aggressive initial rtial therapy continued for 3 months would improve these patients’ morbidity and mortality following an acute MI. Studies have shown that insulin may have a role in restoring other cardiac and ddigami dysfunctions common in diabetic patients.

Regulation of glucose uptake in muscle. In Brief People with diabetes who suffer an acute myocardial infarction MI are at markedly increased risk of future cardiovascular morbidity and mortality.

In Diabetes and Heart Disease. N Engl J Med Thus, some researchers believe diabetic patients may show a greater benefit when heart rate, and thus myocardial oxygen demand, is decreased.



The heart’s demand for more oxygen cannot be met trail the blood supply because of the infarction process. This shift from glucose use to free fatty acid use increases the oxygen demand of the heart muscle. This study did not provide data showing a direct relationship between insulin-glucose infusion and the decreased mortality at 1 year.

Outcome of patients with diyami mellitus and acute myocardial infarction treated with thrombolytic agents: Clinical course of myocardial infarction among diabetic patients.

In reviewing this study’s population, patients who were not willing or able to commit to trlal were excluded. The diagnosis of MI was divided into probable or possible using conventional criteria Table 1. Myocardial infarction in patients with diabetes mellitus.

This in itself may have created a bias because the patients studied were required to agree to aggressive insulin therapy for an extended period of time. High cardiac risk was determined by two or more of the following: Eur Heart J
