Relationship between the severity of mitral regurgitation, left ventricular dysfunction and plasma brain natriuretic peptide level: An observational strain imaging study

Öz

Amaç: Bu çalışmada mitral yetersizliği ve strain/strain rate (S/SR) ekokardiyografi ile tespit edilen sol ventrikül disfonksiyonunun derecesi ile plazma beyin natriüretik peptid seviyesi arasındaki ilişkinin araştırılması amaçlanmıştır.Gereç ve yöntem: Mevcut çalışma kesitsel, gözlemsel bir çalışmadır. Bu çalışmaya polikliniğimize başvurmuş olan ardışık 31 mitral yetersizliği hastası (15’i [%48,4] erkek) ve kontrol grubu olarak 25 sağlıklı birey (12’si [%48,0] erkek) alınmıştır. Hastalar orta derecede mitral yetmezliği olanlar (n=14 [%45,2] ve ileri derecede mitral yetmezliği olanlar (n=17 [%54,8] olarak iki gruba ayrılmışlar ve üç grupta sol ventrikül duvar segmentlerinin maksimum strain / strain rate ölçümleri kaydedilmiş, plazma beyin natriüretik peptit seviyeleri ölçülmüştür.Bulgular: İleri MY olan hastalarda orta MY ve kontrol grubu ile karşılaştırıldığında ileri MY grubunda sol ventrikül segment S/SR değerlerinde daha belirgin azalma izlendi (p
