Popis: | In light of increased risk of cardiovascular events and the poor prognosis of coronary artery disease (CAD) in diabetic versus non-diabetic patients and also with respect to the importance of early diagnosis of CAD in this status, the study was aimed to assess the importance of microalbuminuria in predicting silent myocardial ischemia (SMI) in patients with type 2 diabetes using myocardial perfusion imaging (MPI).This study included 120 patients with diabetes type 2, but without previously known CAD or any cardiac symptoms that were stratified into two groups based on presence/absence of microalbuminuria. All participants underwent CAD evaluation using gated myocardial perfusion single-photon emission computed tomography (MPS) imaging. Other clinical and laboratory indices were also recordedStudied population consisted of 84 males (70%) and 36 females (30%), totally 120 patients with mean age of 58.61±9.90). In total, asymptomatic ischemia was detected in 78 (65%) of the included diabetic patients. Stress induced ischemia was found in 56 patients (87.5%) of albumin+ (Alb) group and in 22 patients (39.3%) of Alb- group. The frequency of stress induced ischemia was 10.81 times higher in the patients with microalbuminuria compared to Alb- ones [p0.001, Odds ratio: 10.81, 95% confidence interval: 4.33-26.99]. On the other hand, no relationship was found between the presence of stress induced ischemia and therapy type, diabetes duration, history of evident retinopathy, history of hypertension and also serum levels of hemoglobin A1c (p0.05).The current study showed that abnormal MPI findings are significantly more common in diabetic patients with microalbuminuria. With respect to low cost and availability of urine Alb detection tests, it might be as a biomarker for prediction of SMI in daibetic population.Bu çalışmada diyabetik olgularda diyabetik olmayanlara göre kardiyovasküler olay riskinin yüksek ve koroner arter hastalığı (CAD) prognozunun kötü olmasından yola çıkarak tip 2 diyabette CAD’nin erken tanısında mikroalbuminürinin önemi miyokard perfüzyon sintigrafisinde (MPS) saptanan sessiz miyokard iskemisi (SMİ) bulguları ile birlikte değerlendirilmektedir.Önceden bilinen CAD ve kardiyak semptomu bulunmayan tip 2 diyabetli 120 olgu çalışmaya dahil edilerek mikroalbuminüri varlığına/yokluğuna göre iki gruba ayrılarak incelendi. Tüm hastalara CAD’yi değerlendirmek üzere miyokard perfüzyon tek-foton emisyonlu bilgisayarlı tomografi ile görüntüleme yapıldı. Ayrıca diğer klinik ve laboratuvar verileri toplandı.Çalışma grubu 84 erkek (%70) ve 36 kadından (%30) oluşan, yaş ortalaması 58,61±9,90 olan 120 hastalık bir gruptur. Gruba dahil edilen diyabetik olguların 78’inde (%65) asemptomatik iskemi saptandı. Albumin+ (Alb) olguların 56’sında (%87,5), Alb- olguların 22’sinde (%39,3) stres iskemisi bulundu. Mikroalbuminüri bulunan olgularda stres iskemisi sıklığı diğerlerine göre 10,81 kez fazlaydı [p0,001, Odds oranı: 10,81, %95 güven aralığı: 4,33-26,99]. Öte yandan, stres iskemisi ile tedavi tipi, diyabetin süresi, bariz retinopati öyküsü, hipertansiyon ve serum hemoglobin A1c düzeyi arasında ilişki bulunmadı (p0,05).Bu çalışma mikroalbuminürisi bulunan diyabetik olgularda MPS’sinde anormal bulguların daha sık olduğunu göstermektedir. Düşük maliyeti ve kolay temini nedeniyle idrarda albumin ölçümü diyabetik popülasyonda SMİ’yi öngörmede bir biyobelirteç olarak kullanılabilir. |
