Abstract

This study investigates the reliability of calculating ejection fraction (EF) and mean circumferential fiber shortening velocity (VCF) via apexcardiography in comparison to left ventricular angiography in 40 patients with coronary artery disease and 14 healthy subjects. Patients were divided into two groups based on left ventricular wall motion abnormalities. Statistically significant correlations were observed between results obtained from both methods. Due to its noninvasive and repeatable nature, apexcardiography is recommended as a reliable alternative for assessing left ventricular performance—especially in patients considered for surgical intervention.

Koroner Damar Hastalarında Apekskardiyografi ile Ejeksiyon Fraksiyonu ve Ortalama Çevresel Lif Kısalma Hızı (VCF)’nin Hesaplanması

Abstract

Bu çalışma, koroner arter hastalığı olan 40 hasta ve 14 sağlıklı bireyde sol ventrikül sistolik fonksiyonlarını değerlendirmek amacıyla ejeksiyon fraksiyonu ve ortalama çevresel lif kısalma hızı (VCF) parametrelerinin apekskardiyografi ve sol ventrikül anjiyografisi ile hesaplanabilirliğini karşılaştırmalı olarak analiz etmektedir. Sol ventrikül duvar fonksiyonlarına göre hastalar iki gruba ayrılmıştır. Her iki yöntemin sonuçları arasında istatistiksel olarak anlamlı bir korelasyon bulunmuştur. Apekskardiyografi ile elde edilen ölçümler, invaziv olmayan, tekrarlanabilir ve pratik olması nedeniyle özellikle cerrahi müdahale planlanan hastalarda sol ventrikül performansının değerlendirilmesinde güvenilir bir alternatif olarak önerilmektedir.
