Summary

The study is aimed at patients who suffer from severe obesity and receive a computerised tomography (CT) scan of the heart. A total of 1200 patients across Europe are to take part in the study. It is a multi-centre, controlled, open, randomised study. As part of the study, a citizen app will be installed on a smartphone for randomly selected study participants. A fitness tracker will also be issued so that certain parameters, such as heart rate and daily number of steps, can be recorded.

Detailed description

The clinical validation study of the AI-POD instruments (risk score, CDSS, Citizen App) is designed as a prospective, multicentre observational study. Obese patients (BMI \>30 kg/m2) with suspected CVD who are scheduled for a cardiac CT scan (consisting of calcium scoring and coronary CT angiography) will be included in the study. This clinically indicated cardiac CT scan will serve as a baseline examination, and a second cardiac CT scan will be performed after a follow-up period of 2 years. Both cardiac CT examinations will be performed on a photon-counting CT system (PCCT). In addition to the CT data, clinical data (anthropometry and physical parameters such as body weight, height, age, gender, BMI, waist circumference, waist-to-hip ratio, body impedance analysis, cardiovascular risk factors, medication, previous interventions and operations) will be collected, symptoms and results of echocardiography to determine left ventricular function) as well as laboratory data on (subclinical) inflammation (hsCRP, leukocytes, monocyte activation), lipid disorders (HDL, LDL, total cholesterol, triacylglycerides), glucose homeostasis (HbA1c, fasting glucose, HOMA index), liver and kidney function (creatinine, GFR, GOT/ALAT, GPT/ASAT) are collected at a total of 5 visits over 2 years. Half of all included patients will also be randomised to receive access to the Citizen app and a separate fitness tracker device to record the following data: Activity data such as step count, heart rate, height, weight, gender, age, waist circumference circumference, nutritional data such as calorie intake, nicotine, alcohol, sleep.
