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.

Background: Echocardiographic ventricular function predicts prognosis and guides management in patients with acute coronary syndromes. In elderly patients, interpretation of echocardiographic measurements may be difficult, especially regarding assessment of diastolic left ventricular function.

Objectives: To examine the usefulness of echocardiographic systolic and echocardiographic diastolic LV[1] function measurements as predictors of long-term outcome in elderly patients with ACS[2].

Methods: We studied 142 consecutive elderly patients (≥ 70 years old, mean age 80 ± 6 years) with ACS who had an echocardiogram at index hospitalization and were in sinus rhythm. LV ejection fraction and diastolic mitral inflow pattern were examined as predictors of survival and repeat hospitalization over a period of 18–24 months.

Results: During the 2 year mean follow-up period 35/142 patients died (25%). Survival was lower in patients with EF[3] < 40% (n=42) as compared to EF ≥ 40% (n=100) (2 year survival rate 61% vs. 81%, P = 0.038). Patients with severe diastolic dysfunction (a restrictive LV filling pattern, n=7) had a lower survival rate than those without (43 vs. 76%, P = 0.009). The most powerful independent predictor of mortality was a restrictive filling pattern (hazard ratio 4.6, 95% confidence interval 1.6–13.5), followed by a clinical diagnosis of heart failure on admission and older age. Rate of survival free of repeat hospitalization was low (33% at 18 months) but repeat hospitalization was not predicted either by EF or by a restrictive filling pattern.

Conclusions: As in the young, echocardiographic measurements of systolic and diastolic LV function predicted long-term survival in elderly patients with ACS. A restrictive filling pattern was the strongest independent predictor of mortality.
