Brief Summary:

Our investigation studies the role of acute insulin administration on the diabetic heart, its corresponding effective blood-insulin level and the time-course applicability of insulin in a routine clinical setting.

A case series of six male (48.1 ± 4.9 y/o) patients with controlled diabetes (HbA1c of 6.6 ± 0.3%, disease duration of 14.4 ± 6.7 yr). Each subject was evaluated for glucose homeostatic, hemodynamic and echocardiographic systolic and diastolic parameters at baseline and following two successive insulin-load steps of a euglycemic hyperinsulinemic clamp study, each 2 h in duration. Results are presented as a mean ± SEM and analysed using the student's t-test.

Arm Intervention/treatment
Experimental: Diabetic patients

Diabetic patients were treated with insulin loads, left ventricle functional parameters were compared to those of healthy persons.

Metabolic indices of insulin effect: blood insulin levels, glucose disposal rates under insulin infusion, were compared to respective group of healthy persons, studied earlier at our institution Insulin LISPRO intravenous loading

Drug: Insulin LISPRO intravenous loading
intravenous infusion of insulin Lispro.
Other Name: Humalog Insulin

Primary Outcome Measures :
  1. Left ventricle ejection fraction (%) [ Time Frame: 1 year ]

Secondary Outcome Measures :
  1. Time needed to exert insulin effect on myocardial function (hour) [ Time Frame: 1 year ]
    Describe the shortest time required for insulin to change myocardial function.

Other Outcome Measures:
  1. Blood insulin levels (μU/ml: micro international unit per milliliter) [ Time Frame: 1 year ]
  2. Left ventricle fractioning shortening (%) [ Time Frame: 1 year ]
  3. E wave (centimeter per second) [ Time Frame: 1 year ]
  4. A wave (centimeter per second) [ Time Frame: 1 year ]
  5. E deceleration time (seconds) [ Time Frame: 1 year ]
  6. E' (centimeters) [ Time Frame: 1 year ]
  7. A' (centimeters) [ Time Frame: 1 year ]
