Key result
Continual arterial dP/dtmax monitoring was significantly correlated with left ventricular dP/dtmax assessed using echocardiography (r = 0.70) in patients with acute heart failure.
Why the study?
Continuous evaluation of left ventricular contractile function in advanced heart failure requiring intensive care is challenging, and the relationship between arterial dP/dt max and LV dP/dt max remains unclear.
Does arterial dP/dtmax correlate with echocardiographic LV dP/dtmax in patients with acute heart failure?

Effect estimate: r = 0.70 (95% CI 0.51-0.82)
p-value: p=<0.0001
Continual measurement of arterial dP/dtmax from an arterial line provides a reliable, minimally invasive estimate of left ventricular contractility in acute heart failure patients, particularly those with cardiogenic shock profiles.

May support arterial dP/dtmax as a continuous LV contractility surrogate in acute HF; leaves open prospective validation before clinical adoption.
Ošťádal et al. (2019) conducted an observational in Acute heart failure (n=48). Arterial dP/dtmax monitoring vs. Echocardiographic LV dP/dtmax was evaluated on Correlation between arterial dP/dtmax and LV dP/dtmax (r = 0.70, 95% CI 0.51-0.82, p=<0.0001). Continual arterial dP/dtmax monitoring was significantly correlated with left ventricular dP/dtmax assessed using echocardiography (r = 0.70) in patients with acute heart failure.
