Ninety asymptomatic patients with type 2 diabetes (48 men; mean age; 49 +/- 6 years) were included in the study. Mean duration of diabetes in the study group was 4 +/- 4.2 years (range 1 to 21 years); 38% of the study population, diabetes duration was only 1 year). All patients were subjected to treadmill exercise test with Bruce protocol. A positive test was noted in 4 of 90 (4%) study patients. Two male patients (4%) and 2 (4%) women patients developed exercise-induced ST-segment depression, but none had concomitant chest pain. Diabetics with silent myocardial ischemia were older (55 +/- 3 years vs 49 +/- 6 years, p = 0.04) than those without silent myocardial ischemia. Also, diabetics with silent myocardial ischemia had higher fibrinogen level (372 +/- 51 vs 307 +/- 71 mg/dL, p = 0.04) than diabetics without silent myocardial ischemia. In treadmill exercise test, diabetics with silent myocardial ischemia had lower total exercise time and peak workload (375 +/- 30 vs 474 +/- 115 seconds, p = 0.04; 7.3 +/- 0.5 vs 8.9 +/- 1.9, p = 0.04, respectively) than without silent myocardial ischemia. Insulin resistance is associated with a variety of atherosclerosis risk factors. Exercise test findings show increased cardiac sympathetic activity and parasympathetic withdrawal in increased insulin resistance.en10.1177/0003319707307765info:eu-repo/semantics/closedAccessHomeostasis Model AssessmentInsulin-ResistanceMellitusDiseaseConference Object585535542Q4WOS:0002503930000032-s2.0-3544893805518024935Q2
