Key result
Patients with acute leukemia exhibited lower left ventricular diastolic function compared to those with iron deficiency anemia (E/A ratio 1.1 vs 1.42, p < 0.05).
Why the study?
Does acute leukemia affect left ventricular systolic and diastolic function compared to iron deficiency anemia?
Observational (n=36)
Does acute leukemia affect left ventricular systolic and diastolic function compared to iron deficiency anemia?
Patients with acute leukemia exhibit left ventricular diastolic dysfunction more frequently than anemic controls, which may be an early indicator of restrictive cardiomyopathy.

Acute leukemia may link to diastolic dysfunction beyond anemia alone; hypothesis-generating for cardiomyopathy risk, needing prospective confirmation.
Eighteen patients with acute leukemia were studied to evaluate their left ventricular systolic and diastolic function by M mode, two-dimensional and Doppler echocardiographic techniques. The study group was compared with another group of 18 patients of similar age with iron deficiency anemia. The latter group had a comparable heart rate and levels of Hb. There were no differences in systolic function, whereas the diastolic function was lower in patients with acute leukemia (E/A ratio = 1.1 +/- 0.3 vs. 1.42 +/- 0.5, p < 0.05). It is concluded that left ventricular diastolic dysfunction is more common in patients with acute leukemia and may be an indicator of restrictive cardiomyopathy.

Tunçkale et al. (1999) conducted an observational in Acute leukemia (n=36). Acute leukemia vs. Iron deficiency anemia was evaluated on Left ventricular diastolic function (E/A ratio) (p=< 0.05). Patients with acute leukemia exhibited lower left ventricular diastolic function compared to those with iron deficiency anemia (E/A ratio 1.1 vs 1.42, p < 0.05).
