Echocardiographic Analysis by Artificial Intelligence in Hypertension

Condition(s) studied

Investigational drug(s) / intervention(s)

Clinical cardiac parameters (Arterial pressure, number of anti-hypertensive medications, and the NT-proBNP measurements): The degree of severity of the hypertension will have been previously diagnosed for each patient with the help of the blood pressure measurements, the number of antihypertensive treatments and the NT-proBNP measurement which is correlated with the left intraventricular pressure and the mass of the left ventricle. This information will be used (i) to guide the structuring of the pathology representation space during the learning phase from a sub-population (a portion of the collected database that will be used for training algorithms); (ii) to serve as an endpoint from a test sub-population (the remaining portion of the database collected).

Study summary

The objective of this study is to develop artificial intelligence (AI) tools to characterize cardiac remodelling in arterial hypertension through the analysis of routine imaging data (echocardiography) coupled with patient data. More precisely, this study will make it possible (i) to represent in a relevant way the spectrum of the cardiac repercussions of a population affected by hypertension to better characterize the progress of the pathology, in particular vis-à-vis the more ambiguous subjects to be characterized ("grey" area); (ii) to develop tools for the automatic quantification of cardiac function (segmentation and robust monitoring of the myocardium during the cardiac cycle, for the dynamic analysis of the shape and global deformation of the heart) and therefore to extract descriptors richer in cardiac function than those currently used in clinical routine.

Eligibility

Primary outcome measure(s)

• Arterial Blood Pressure — Baseline
  This measure will assess the arterial blood pressure in millimeters of mercury (mmHg). Blood pressure measurements will include both systolic and diastolic values. This measurement will be used to evaluate the severity of hypertension and track changes over the course of the study.
• Number of Antihypertensive Medications — Baseline
  This measure will record the number of antihypertensive medications prescribed to each patient. The data will be used to assess the intensity of the treatment regimen required to control blood pressure levels in participants. Unit of Measure: Count of medications (integer)
• NT-proBNP Concentration — Baseline
  This measure will assess plasma concentrations of N-terminal pro b-type natriuretic peptide (NT-proBNP), a biomarker correlated with left ventricular pressure and mass. NT-proBNP levels will be analyzed in picograms per milliliter (pg/mL) to evaluate cardiac stress associated with hypertension.
