Abstract

OBJECTIVES:

We sought to assess whether in clinically stable patients with chronic heart failure (CHF) the prolongation (i.e., increase) of an initially short (< or = 125 ms) Doppler transmitral deceleration time (DT) of early filling obtained with long-term optimal oral therapy predicts a more favorable prognosis.

BACKGROUND:

It has been recently demonstrated that transmitral early DT is a powerful independent predictor of poor prognosis in patients with left ventricular dysfunction. However, DT may change over time according to loading conditions and medical treatment.

METHOD:

One hundred forty-four patients with CHF and a short DT (< or = 125 ms) underwent repeat Doppler echocardiographic study 6 months after the initial examination, while clinically stable with optimal oral therapy, and were then followed up for a mean period of 26 +/- 7 months.

RESULTS:

After 6 months, DT had not changed in 80 patients (group 1), whereas it was significantly prolonged (> 125 ms) in the remaining 64 patients (group 2). Baseline Doppler echocardiographic features were similar in the two groups. No changes were found after 6 months in group 1, whereas group 2 showed a slight but significant (p < 0.01) reduction in end-systolic volume, an improvement in left ventricular ejection fraction (p < 0.01) and a decrease (p < 0.01) in the degree of tricuspid regurgitation. During follow-up, 37% of patients in group 1 experienced cardiac death versus 11% in group 2 (p < 0.0005). By Cox model analysis, prolongation of a short DT emerged as the single best predictor of survival (chi-square 15.70).

CONCLUSIONS:

The prolongation of an initially short DT obtained with long-term optimal oral therapy predicts a more favorable outcome in clinically stable patients with CHF.
