Introduction: Because
only a small proportion of patients undergoing coronary angiography have
obstructive coronary artery disease (CAD), further markers are necessary to
predict CAD severity. The aim of our study was to investigate the importance of
P wave dispersion for predicting obstructive CAD and its severity in patients
undergoing coronary angiography for positive myocardial perfusion scintigraphy.



Patients and Methods:
Overall,
126 patients who underwent coronary angiography for positive myocardial
perfusion scintigraphy were included in the study. The patients were divided
into three groups based on coronary angiography findings: group 1, patients
with non-obstructive CAD; group 2, patients with obstructive CAD in only one
vessel; and group 3, patients with obstructive CAD in more than one vessel. The
groups were compared for P wave duration and P wave dispersion. Gensini score
was used to evaluate CAD severity.



Results: There was
no significant difference among the groups regarding P wave duration at rest.
However, there was a significant difference among the groups regarding P wave
duration at recovery (117.10 ± 13.69 msn, 127.64 ± 12.70 msn, 130.51 ± 11.84
msn, respectively, p< 0.001). When the groups were compared for P wave
dispersion, we found a statistical significant difference among the groups
(13.63 ± 6.38 msn, 22.48 ± 3.98 msn, 27.14 ± 6.22 msn, respectively, p<
0.001). There was a positive correlation between P wave dispersion and Gensini
score (r= 0.390, p< 0.001).



Conclusion: Our findings suggested that
P wave dispersion increases the sensitivity and specificity of positive
myocardial perfusion scintigraphy for predicting obstructive CAD and its
severity.

Giriş: Koroner anjiyografi uygulanan hastaların sadece küçük bir kısmında
tıkayıcı koroner arter hastalığı (KAH) saptandığı düşünüldüğünde, KAH
ciddiyetini öngörebilecek yeni belirteçlerin saptanması önem taşımaktadır.
Çalışmamızın amacı, stabil KAH ile başvuran ve miyokart perfüzyon
sintigrafisinde iskemi saptanması nedeniyle 
koroner anjiyografi uygulanan hastalarda tıkayıcı KAH varlığı ve KAH
yaygınlığını öngörmede P dalga dispersiyonun önemini test etmektir



Hastalar ve
Yöntem:
Miyokart perfüzyon sintigrafisinde  iskemi saptanması nedeniyle koroner
anjiyografi uygulanan 126 hasta çalışmaya dahil edildi. Anjiyografi sonucuna
göre hastalar tıkayıcı KAH saptanmayan (grup 1), tek damarda tıkayıcı KAH
saptanan (grup 2) ve birden fazla damarda tıkayıcı KAH saptanan hastalar (grup
3 ) olmak üzere üç gruba ayrıldı. Gruplar P dalga süreleri ve P dalga
dispersiyonu açısından birbirleriyle karşılaştırıldı. KAH yaygınlığını
değerlendirmek için Gensini skoru kullanıldı.



Bulgular: İstirahat P dalga süreleri açısından gruplar birbiriyle
karşılaştırıldığında, üç grup arasında istatistiksel olarak anlamlı fark
saptanmazken, P dalga recovery süreleri açısından gruplar birbiriyle
karşılaştırıldığında ise, üç grup arasında istatistiksel olarak anlamlı fark
saptandı (sırasıyla 117.10 ± 13.69 msn, 127.64 ± 12.70 msn, 130.51 ± 11.84 msn,
p< 0.001). P dalga dispersiyonu açısından gruplar birbiriyle
karşılaştırıldığında, her üç grup arasında da istatistiksel olarak anlamlı fark
saptandı (sırasıyla 13.63 ± 6.38 msn, 22.48 ± 3.98 msn, 27.14 ± 6.22 msn, p<
0.001). P dalga süre değişikliği ve Gensini skoru arasında  pozitif yönde korelasyon izlendi. P dalga
süre değişikliği arttıkça Gensini skorunun da arttığı tespit edildi ( r= 0.390,
p< 0.001).



Sonuç: Çalışmamızın sonuçları
miyokart perfüzyon sintigrafisi sonucuna P dalga dispersiyonunun eklenmesinin
tıkayıcı KAH ve KAH yaygınlığını belirlemede testin duyarlılığını ve
özgüllüğünü anlamlı olarak artırdığını göstermektedir.
