The success of MDCT according to the localization was as follows: nine in 10 proximal segments (sensitivity 90%, specificity 98.4%, positive predictive value 90%, negative predictive value 98.4%); seven in 12 middle segments (sensitivity 58.3, specificity 95.8%, positive predictive value 87.5%, negative predictive value 82.1%); and three in 14 distal segments (sensitivity 21.4, specificity 92.5%, positive predictive value 50%, negative predictive value 77.1%).Conclusion: Multidetector computed tomography can be safely used as a noninvasive imaging method in the assessment of proximal and, in part, middle coronary artery segments.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objectives: The success of multidetector computed tomography (MDCT) was assessed in detecting coronary artery stenoses in patients with angiographically proven coronary artery disease following acute myocardial infarction.Study design: Eighteen patients (6 women, 12 men; mean age 51.3 years) who were hospitalized with the diagnosis of acute myocardial infarction underwent coronary angiography after clinical stabilization was restored.
📊
Key Findings & Data:Segments that were angiographically shown to have stenosis exceeding 50% of the coronary artery lumen were evaluated by MDCT.Results: Of 288 segments studied, coronary angiography showed more than 50% stenosis in 48 segments, of which 24 segments (50%) were also demonstrated by MDCT (sensitivity 50%, specificity 97.5%).
💡
Conclusion & Impact:The success of MDCT according to the localization was as follows: nine in 10 proximal segments (sensitivity 90%, specificity 98.4%, positive predictive value 90%, negative predictive value 98.4%); seven in 12 middle segments (sensitivity 58.3, specificity 95.8%, positive predictive value 87.5%, negative predictive value 82.1%); and three in 14 distal segments (sensitivity 21.4, specificity 92.5%, positive predictive value 50%, negative predictive value 77.1%).Conclusion: Multidetector computed tomography can be safely used as a noninvasive imaging method in the assessment of proximal and, in part, middle coronary artery segments.

Abstract

Objectives: The success of multidetector computed tomography (MDCT) was assessed in detecting coronary artery stenoses in patients with angiographically proven coronary artery disease following acute myocardial infarction.Study design: Eighteen patients (6 women, 12 men; mean age 51.3 years) who were hospitalized with the diagnosis of acute myocardial infarction underwent coronary angiography after clinical stabilization was restored. Within two days of coronary angiography MDCT was performed. Segments that were angiographically shown to have stenosis exceeding 50% of the coronary artery lumen were evaluated by MDCT.Results: Of 288 segments studied, coronary angiography showed more than 50% stenosis in 48 segments, of which 24 segments (50%) were also demonstrated by MDCT (sensitivity 50%, specificity 97.5%). The success of MDCT according to the localization was as follows: nine in 10 proximal segments (sensitivity 90%, specificity 98.4%, positive predictive value 90%, negative predictive value 98.4%); seven in 12 middle segments (sensitivity 58.3, specificity 95.8%, positive predictive value 87.5%, negative predictive value 82.1%); and three in 14 distal segments (sensitivity 21.4, specificity 92.5%, positive predictive value 50%, negative predictive value 77.1%).Conclusion: Multidetector computed tomography can be safely used as a noninvasive imaging method in the assessment of proximal and, in part, middle coronary artery segments.

Özet

Amaç: Akut miyokard infarktüsü geçiren hastalarda, koroner anjiyografiyle kanıtlanmış koroner arter darlığının belirlenmesinde multidedektör bilgisayarlı tomografinin (MDBT) başarısı araştırıldı.Çalışma planı: Akut miyokard infarktüsü tanısıyla hastaneye yatırılan 18 hastaya (6 kadın, 12 erkek; ort. yaş 51.3) klinik açıdan stabilizasyon sağlandıktan sonra koroner anjiyografi yapıldı. Daha sonra, iki gün içinde MDBT uygulandı. Koroner anjiyografiyle koroner arter lümeninde %50’den fazla darlık görülen segmentler belirlendi ve bu segmentler MDBT ile değerlendirmeye alındı.Bulgular: Koroner anjiyografi ile değerlendirilen 288 segmentin 48’inde %50 üzerinde darlık saptandı. Bu lezyonların 24’ü (%50) MDBT ile görüntülenebildi (duyarlılık %50, özgüllük %97.5). Multidedektör bilgisayarlı tomografi, proksimal segmentlerde koroner anjiyografiyle belirlenen 10 lezyonun dokuzunda (duyarlılık %90, özgüllük %98.4, pozitif öngördürücü değer %90, negatif öngördürücü değer %98.4); orta segmentlerde 12 lezyonun yedisinde (duyarlılık %58.3, özgüllük %95.8, pozitif öngördürücü değer %87.5, negatif öngördürücü değer %82.1); distal segmentlerde 14 lezyonun üçünde (duyarlılık %21.4, özgüllük %92.5, pozitif öngördürücü değer %50, negatif öngördürücü değer %77.1) başarılı bulundu.Sonuç: İnvaziv olmayan bir görüntüleme yöntemi olan MDBT, proksimal koroner arter segmentlerinin ve göreceli olarak orta segmentlerin değerlendirilmesinde güvenle kullanılabilir.
