El dominansı ve koroner dominans arası ilişki

Amaç: Koroner arter hastalığının bilinen risk faktörlerinin dışında, koroner dominans, ektazi, bifürkasyon açısı gibi anatomik risk faktörleride mevcuttur. Fonksiyonel bir serebral lateralizasyon olarak kabul edilen el dominansının bazı hastalıklarla ilişkisi daha önce tanımlanmıştır. Bu çalışmanın amacı genetik faktörler ile belirlenen el dominansı ve koroner dominans arası ilişkiyi tanımlamaktır.Gereç ve Yöntemler: Polikliniğe başvuran, koroner anjiyografi uygulanmış 226 hastanın koroner anjiyografileri değerlendirildi. Hastalar sağ koroner dominant, sol dominant ve dengeli dominant olarak gruplandırıldı. Hastaların el tercihlerini belirlemek için "Oldfield Anketi" kullanıldı. Hastalar sağ el baskın, sol el baskın ve her iki elde baskınlık olarak üç gruba ayrıldı. Koroner dominans ve el dominansı arasındaki ilişki araştırıldı.Bulgular: Anjiyografisi yapılan 226 hastanın 96'sı (%42,5) kadın, 130' u (%57,5) erkekti. 170 hasta (%75, 2) sağ el, 14 hasta sol el (%6,2) ve 42 hasta (%18,6) her iki el baskınlığına sahipti. 160 hastada sağ koroner dominans (%70, 8), 26 hastada sol koroner dominans (%11,5) ve 40 hastada (%17,7) dengeli koroner dominans belirlenmiştir. El dominansı ile cinsiyet arasında istatiksel olarak anlamlı fark bulunamamıştır (p: 0,309). Koroner dominans ve cinsiyet arası anlamlı bir ilişki saptanmamıştır (p:0,114). Koroner arter dominansı ile serebral fonksiyonel dominans arasında istatistiksel olarak anlamlı bir ilişki vardır (p: 0,005). Sonuç: Çalışmamızda koroner arter dominansı ve serebral fonksiyonel dominans arasında istatistiksel olarak anlamlı bir ilişki saptanmıştır. Ancak serebral ve koroner dominansı anatomik düzeyde karşılaştırmak için dominant hemisferi daha net olarak gösteren invaziv bir test olan wada testi ile yapılacak ileri çalışmalara ve anatomik lateralizasyonu karşılaştıran kadavra çalışmalarına ihtiyaç vardır.

Relationship between hand dominance and coronary dominance

Aim: Coronary artery disease is present in anatomic risk factors such as dominance, ectasia, bifurcation angle other than standard risk factors. The association of cerebral lateralization and hand dominance with some diseases has been described previously. The aim of this study is to investigate the relationship between hand dominance and coronary dominance determined by genetic factors.Material and Methods: Coronary angiograms of 226 patients who underwent coronary angiography were evaluated for coronary dominance. Patients were grouped as right, left and balanced dominance. The "Oldfield Survey" was used to determine patients' hand preferences. Patients were divided into three groups: left-hand, right-hand dominant and ambidextrous patients. The relationship between coronary dominance and hand dominance was investigated.Results: Of the 226 patients who underwent angiography, 96 (42.5%) were female and 130 (57.5%) were male.170 patients (75.2%) had right hand, 14 patients had left hand (6.2%), and 42 patients (18.6%) had both hand dominance. Right coronary artery dominanace was found in 160 patients (70.8%), left coronary dominance in 26 patients (11.5%) and balanced coronary dominance in 40 patients (17.7%). There was no statistically significant difference between hand dominance and gender (p: 0.309). There was a statistically significant relationship between coronary artery dominance and cerebral functional dominance (p: 0.005). Conclusion:In conclusion, there was a significant relationship between coronary artery and cerebral functional dominance. However, cadaver studies are needed to compare cerebral and coronary dominance with advanced studies and anatomical lateralization with the wada test, which is an invasive test that shows us more clearly the dominant hemisphere.
