Abstract

Objective: To identify the Doppler echocardiographic criteria able to predict clinical deterioration of mild-to- moderate chronic heart failure (CHF) as well as, whenever possible, to evaluate the features of chronological relation of cavitary remodelling in left chambers during follow-up (FU). Methods: A retrospective, case-controlled study , including a number of CHF II NYHA class patients, was carried out, to evaluate, by means of univariate and multivariable logistic regression analyses, the role as predictor of CHF worsening of some Doppler echocardiographic parameters, listed as follows: left ventricular mass index, analyzed both as continuous and as dichotomous (>130 g/m2) variable; left ventricular end-systolic volume (LVESV)>57 ml; left ventricular ejection fraction (LVEF), divided into 2 classes: a) LVEF>45%, i.e. normal or mildly impaired LVEF, and 2) reduced (45%-30%) LVEF; restrictive left ventricular filling pattern (RFP); antero-posterior left atrial diameter (LADi) >50 mm; ratio of early mitral inflow to early myocardial velocity>8. Results: Of 173 patients enrolled, 60 patients (15 cases of transition to III NYHA class and 45 controls) were included in retrospective analysis. At univariate analysis, RFP and LADi>50 mm were shown to be associated with worsening of CHF. At multivariate analysis, the role of prognostic indicator of poor outcome was maintained by RFP (OR=17.0, 95%CI: 2.5-116.5) as well as by LADi>50 mm (OR=7.95, 95%CI: 1.27.0-49.6). On the other hand, in the subset of CHF with LVEF >45%, increased LADi was not associated with occurrence of increase in LVESV or left ventricular progressive dilation during the subsequent follow-up. Conclusions: In mild-to-moderate CHF, RFP and LADi>50 mm are predictors of adverse outcome, independently of the presence or severity of left ventricular systolic dysfunction.

Özet

Amaç: Hafif-orta kronik kalp yetersizliği (KKY) klinik kötüleşmesinin belirlenmesi için Doppler ekokardiyografik kriterlerin saptanması. Ayrıca, mümkün olduğunca da takip süresinde sol odacıkların kavite remodelling’inin zamanla görünümünün değerlendirilmesi. Yöntemler: Retrospektif, olgu-kontrol çalışmasında KKY NYKD sınıf II hastalar alınarak incelendi ve Doppler ekokardiyografik kriterlerinin KKY klinik kötüleşmesinin öngörme değerleri tek-yönlü ve çok-yönlü lojistik regresyon analizleri ile değerlendirildi. Aşağıda listesi verilen bazı Doppler ekokardiyografik parametreler KKY’nin kötüleşme parametreleri olarak analiz edildi; sol ventrikül sistol sonu volüm (SVSSV) >57 ml; sol ventrikül ejeksiyon fraksiyonu (SVEF), iki sınıfa ayrılarak: a) SVEF >%45 (normal ya da hafif bozuk SVEF) ve b) azalmış (%45-30) SVEF; restriktif sol ventrikül doluş örneği (RDÖ); ön-arka sol atriyum çapı (SAÇ) >50 mm; erken mitral doluşunun erken miyokard velositesine oranı >8. Bulgular: Yüz yetmiş üç hasta alındı, bunların 60’ı (15 olgu NYKD sınıf III’e geçti ve 45 kontrol) retrospektif analize dahil edildi. Tek-yönlü analizde, RDÖ ve SAÇ >50 mm KKY kötüleşmesi ile birlikte görüldü. Çok-yönlü analizde (RDÖ) (OR=17.0, %95 CI:12.5-116.5), ayrıca da SAÇ >50 mm (OR=7.95, %95 CI:1.27-49.6) kötü sonuçların prognostik belirlemede de rolü olduğu anlaşıldı. Diğer taraftan, takip sırasında sol ventrikül ilerleyici dilatasyonu ya da SVSSV’unda artmasında SVEF >%45 ve SAÇ’ın belirleyici rolü tespit edilmedi. Sonuç: Hafif-orta KKY’inde RDÖ ve SAÇ >50 mm sol ventrikül disfonksiyonunun varlığı ya da şiddetinden bağımsız kötü sonuçların belirleyicisidir.
