Predicting Ventricular Tachyarrhythmias Following Acute ST Elevation Myocardial Infarction (PREDICT-VT)
Study Overview
Detailed Description
Study design Predict-VT is an investigator-initiated, prospective, open-label, single-center clinical trial. The research protocol has been approved by the Ethics Committee of the Clinical Center of Serbia. All participants will have to provide their informed consent in writing. The trial design will ensure that all participants abide by good clinical practice and the ethical principles of the Declaration of Helsinki II.
Study population The study will include at least 400 patients with acute myocardial infarction with ST elevation (STEMI) who are elgible for treatment with primary percutaneous coronary intervention (PPCI) within 12 hours from the onset of symptoms. Enrollment started on January 2017 . Recruitment will continue until 400 patients have been randomized. The end of the recruitment period is planned for January 2021. The trial will continue until all available survivors have been followed for at least 1 year.
Objectives, end points and definitions The primary objective of PREDICT-VT trial is to test the hypothesis that the occurrence of ventricular tachyarrhythmias (VTA) and sudden cardiac death (SCD) is predictable with acceptable accuracy among STEMI patients undergoing PPCI. Therefore, the PREDICT-VT specified primary end point is the analysis of independent predictors of VTA and SCD in a period of 3-40 days following STEMI. The second objective of the study is the stratification of risk for VTA by constructing optimal predictive models and defining the classes of risk. The third objective of the study is a validation of the model using an independent sample of patients. The study's subanalyses will include: a. Analysis of the significance of non-sustained VTA lasting <30 seconds for the prognosis of patients with STEMI, b. Importance of frequent ventricular premature beats and/or emerging atrial fibrillation for the prognosis of patients and the emergence of SCD, c. Definition of risk factors for the occurrence of VTA in the subgroup of patients with preserved left ventricular ejection fraction (LVEF), considering that more than half of the SCD victims have preserved LVEF.
Noninvasive and invasive assessment A 24-hour ECG Holter monitoring will be performed in the period of 5 ± 2 days after STEMI.
Echocardiographic examination on Vivid E9 (General Electric) echocardiographic device will be performed 5 ± 2 days after STEMI and repeated after 50 ± 10 days. Standard echocardiographic methods of M-mode, 2D, color, pulse, continuous doppler, tissue doppler and 2D speckle tracking will be used. The analysis will include the parameters of systolic and diastolic functions and myocardial mechanics in accordance with the latest recommendations of the European / American Echocardiographic Association.
The following angiographic variables will be analyzed: significant coronary artery stenosis -localization and number, number of diseased coronary vessels, length of stenosis, type of stenosis, coronary flow before and after the intervention, type and number of implanted stents.
Patients will be followed-up after discharge from hospital for the occurrence of specified end points at 40 days and 1 year after enrollment by scheduled telephone interviews and outpatient visits. An independent Clinical Event Committee, composed of 3 cardiologists will review and adjudicate the occurrence of each suspected clinical end point.

Measure Description |
Time Frame |
---|---|---|
Composite of ventricular tachyarrhythmias and sudden cardiac death
Time Frame: 3-40 days after STEMI
|
Analysis of independent predictors of ventricular tachyarrhythmias and sudden cardiac death in a period of 3-40 days following STEMI.
Predictors will be identified from clinical, laboratory, echocardiographic, angiographic and procedural variables collected in the study database, using statistical methods of univariable logistic regression and Cox proportional hazard model.
Statistical methods of multivariable logistic regression, bootstrapping and receiver operating characteristic curve analysis will be used for the identification of independent predictors of outcome.
