The Relationship of the Extent of Coronary Artery Disease with TIMI Risk Model in Patients with Acute ST Segment Elevation Myocardial Infarction

Öz

OBJECTIVE: Preventive angioplasty may be useful for patients presenting with ST elevation myocardial infarction (STEMI), in whom multivessel disease was detected. TIMI risk scoring may be related to the severity of coronary artery disease (CAD) in these patients. This study aimed to investigate the relationship between the presence of multivessel disease on coronary angiograms and TIMI scores in patients with STEMI.METHODS: Ninety-one patients (73 males; 18 females) who presented with STEMI and treated with angioplasty were enrolled in the study. TIMI scores were calculated for all patients at presentation and the patients were classified into low (0-4) and high (5-14) risk groups based on TIMI scores. The extent of CAD was determined by experienced operators. One-way ANOVA was used for comparisons.RESULTS: Low TIMI risk score group included 70 (76.9%) patients and high TIMI risk score group included 21 (23.1%) patients. Coronary angiography results showed that 44 (48.4%) patients had involvement of 1 vessel, 24 (26.4%) patients had involvement of 2 vessels, and 23 (25.2%) patients had involvement of 3 vessels. There was no relationship between TIMI scores and the extent of CAD in patients (p=0.522).CONCLUSION: There was no association between TIMI scores and the extent of CAD in STEMI patients. TIMI risk scoring may not be useful in triage of STEMI patients. Future studies assessing the relationship between other risk scores and the extent of CAD would be still relevant and of great interest.

Akut ST Yükselmeli Miyokart Enfarktüslü Hastalarda Koroner Arter Hastalığı Yaygınlığının TIMI Risk Modeli ile İlişkisi

Öz

AMAÇ: Koruyucu anjiyoplasti, ST yükselmeli miyokard infarktüsü (STYME)'nde çoklu damar hastalığı saptanan hastalarda faydalı olabilir. TIMI risk skorlaması bu hastalarda koroner arter hastalığı (KAH)'nın yaygınlığı ile ilişkili olabilir. Bu çalışmada, STYME ile başvuran hastaların koroner anjiyografilerinde saptanan çoklu damar hastalığının TIMI skorları ile olan ilişkisinin araştırılması amaçlanmıştır.YÖNTEMLER: Çalışmaya, STYME ile başvuran ve anjiyoplasti ile tedavi edilen 91 (73 erkek; 18 kadın) hasta dahil edilmiştir. Tüm hastalar için başvuru sırasındaki TIMI skorları hesaplanmış, hastalar TIMI skorlamasına göre düşük (0-4) ve yüksek (5-14) risk gruplarına ayrılmıştır. KAH yaygınlığı deneyimli operatörler tarafından belirlenmiştir. Karşılaştırmalar tek yönlü ANOVA yöntemi kullanılarak yapılmıştır. BULGULAR: Düşük TIMI skorlu grupta 70 (%76,9), yüksek TIMI skorlu grupta 21 (%23,1) hasta vardı. Hastaların koroner anjiyografi sonuçlarına göre 44 (%48,4) hastada bir damar tutulumu, 24 (%26,4) hastada iki damar tutulumu, 23 (%25,2) hastada da üç damar tutulumu mevcuttu. Hastaların TIMI skorları ile KAH yaygınlığı arasında bir ilişki yoktu (p=0,522).SONUÇ: STYME hastalarında TIMI skorları ile KAH yaygınlığı arasında ilişki saptanmadı. STYME hastalarının triyajında TIMI risk skorlaması faydalı olmayabilir. Gelecekteki çalışmalarda diğer risk skorlarının KAH yaygınlığı ile olan ilişkisinin araştırılması halen güncel ve incelemeye değer olacaktır.
