Why the study?
Optimization of E-A wave synchrony and morphology improves diastolic filling in patients with CIEDs, prompting evaluation of whether these principles could be applied pharmacologically to patients without CIEDs.
Does pharmacological optimization of E-A wave synchrony and morphology improve LV diastolic function in patients without CIEDs?

Does pharmacological optimization of E-A wave synchrony and morphology improve LV diastolic function in patients without CIEDs?
Applying principles of echocardiographic AV optimization via pharmacological intervention may improve LV diastolic function in patients without CIEDs.
May support ivabradine for E-A optimization in select HFpEF cases; hypothesis-generating and requires prospective trials before practice change.
Heart Failure is a major public health problem globally, affecting about 5.1 million patients in the US, almost 40% of whom have predominantly diastolic left ventricular (LV) dysfunction. Pulsed doppler echocardiography of the mitral inflow, in terms of E-A ratio, is used in the assessment of diastolic function. Besides E-A ratio, optimization of E-A wave synchrony and morphology has also been shown to improve diastolic filling and cardiac hemodynamics in patients with cardiac implantable electronic devices (CIED). In this case report, we applied the principles of echocardiographic AV optimization in CIED patients to patients without CIEDs by pharmacological intervention to improve LV diastolic function.

Patel et al. (2023) conducted a case report in Diastolic dysfunction (HFpEF) (n=1). Ivabradine vs. Baseline was evaluated on Heart rate and E-A wave morphology.
