Prevalence and Significance of Restrictive Filling Pattern in an Echocardiography Laboratory

Summary

Background:

A cardiac restrictive filling patterns are associated with unfavorable prognoses. Cardiac interventions may change the natural history of patients.

Objectives:

To investigate the prevalence of restrictive filling pattern in routine echocardiographic examinations and their association with morbidity and mortality.

Methods:

The clinical and echocardiographic data of patients with newly diagnosed restrictive filling pattern were analyzed and summarized.

Results:

Among 8000 patients who underwent an echocardiographic examination in our hospital in 2013, a restrictive filling pattern was identified in 256. Of these, 134 showed a restrictive filling pattern that was newly diagnosed. Mean age was 69 years. Hypertension, diabetes, and ischemic heart disease were found in 81%, 60%, and 53%, respectively. Left ventricular ejection fraction was 42% ± 16%. Severe valvular abnormalities were found in 18%. During follow-up (29 ± 15 months), 40% of patients died. The strongest predictor of mortality (73%) was moderate or more advanced aortic stenosis, P = 0.005. Renal failure was an important independent predictor of mortality (53%, P < 0.05). A very high E/E' ratio ≥ 20, was another independent mortality predictor (50%, P < 0.03). Patients who died were less likely to have undergone cardiac interventions than those who survived (26% vs. 45%, P < 0.03).

Conclusions:

Prevalence of restrictive filling among echocardiographic studies is 3.2%. In a half of these, the restrictive filling pattern is a new diagnosis. Patients who are diagnosed with a new restrictive filling pattern have higher mortality rates. Patients with restrictive filling should be evaluated thoroughly for possible coronary artery or valvular heart disease.
