About this trial
This study aimed to evaluate the efficacy of non-invasive dynamic blood pressure monitoring in assessing left ventricular outflow tract obstruction in patients with hypertrophic cardiomyopathy. We prospectively collected SBP waveforms and LVOT gradient data from patients with obstructive and non-obstructive disease, systematically analyzed their correlation, and explored its clinical value in different clinical scenarios.

1: ① Age ≤ 18 years, or pregnant/lactating patients
Trial population
HCM patients: In this study, transthoracic echocardiography (TTE) was used as the gold standard. Left ventricular outflow tract obstruction (LVOTO) was defined as a resting left ventricular outflow tract gradient (LVOTG) ≥ 30 mmHg, or an LVOTG ≥ 50 mmHg after provocation tests (e.g., Valsalva maneuver), according
