Abstract

Objective:
This study investigated the association between fragmented QRS and the severity
of carotid artery disease.

Materials
and Methods: 168 patients who underwent carotid
angiography due to transient ischemic attack or ischemic stroke between March
2009 and July 2017 were enrolled in the study. Patients enrolled in the study
were divided into two groups according to severity of carotid artery disease on
carotid angiography. Group One consisted of patients with a carotid stenosis of
<50% (n:82) and group 2 consisted of patients with a carotid stenosis of
≥50% (n:86). Two groups were compared in terms of existence of fragmented QRS on
electrocardiogram prior to carotid endarterectomy by using hospital records.

Results:
The
study group consisted of 168 patients. Group One showed more male predominance
and this indicated a significant difference in terms of gender between two
groups (p=0.026). Existence of chronic obstructive pulmonary disease was more
common in group 2 and this indicated a statistically significant difference
(p=0.001). 12-lead ECG of patients in group 2 tended to demonstrate fQRS much
frequently compared to patients in group 1 (p=0.002).

Conclusion:
fQRS seems to be associated with the severity of CAD and assessment of fQRS can
be a predictive factor to determine high risk patients for concealed coronary
artery disease in patients with severe carotid artery disease and without a
history of coronary artery disease.

Fragmente Qrs Karotis Arter Hastalığının Ciddiyeti ile İlişkili Midir?

Abstract

Amaç: Bu
çalışmada fragmente QRS ile karotis arter hastalığının ciddiyeti arasındaki
ilişki araştırılmıştır.

Gereç
ve Yöntemler: Mart 2009 ve Temmuz 2017 tarihleri arasında
geçici iskemik atak veya iskemik inme nedeni karotis anjiyografi uygulanan 168
hasta çalışmaya dahil edldi. Çalışmaya dahil edilen hastalar karotis
anjiyografideki karotis arter hastalığının ciddiyetine göre 2 sınıfa ayrıldı.
İlk grupta karotis darlığı %50’nin altında olan hastalar var iken (n:82) ikinci
grupta karotis darlığı ≥%50 olan hastalardan oluşmaktaydı (n:86). İki grup
karotis endarterektomi ameliyatı öncesi elektrokardiyogramları taranarak fragmente
QRS varlığı açısından karşılaştırıldı.

Bulgular:
Çalışma
populasyonu toplam 168 hastadan oluşmaktaydı. Birinci grupta erkek cinsiyet
hakimdi ve bu istatistiksel olarak anlamlı idi (p=0.026). Kronik obstruktif
akciğer hatslığı ise ikinci grupta daha fazla idi ve bu istatistiksel olarak
anlamlı idi (p=0.001). İkinci gruptaki hastaların 12 derivasyonlu elektrokardiyogramlarında
fragmente QRS varlığı birinci gruba kıyasla istatistiksel olarak daha fazla idi
(p=0.002).

Sonuç: Fragmente
QRS varlığı karotis arter hastalığının ciddiyeti ile ilişkili görünmektedir. Fragmente
QRS değerlendirilmesi ciddi karotis arter hastalığına sahip olup tanısı
konmamış latent koroner arter hastalığı olan hastaların saptanmasını tahmin
ettirici bir faktör olarak kullanılabilir.
