The First Russian Observational Survey of Heart Failure Patients With

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the management of chronic heart failure patients with atrial fibrillation, to collect data on compliance with clinical guidelines and the prevalence of long-term anticoagulant therapy,complications. The results will be used to develop most rational therapeutic and diagnostic strategies to improve clinical outcomes of such patients.

Clinical Trial Description

Quality assurance plan: investigators are going to plan site monitoring every three months. Any audits are not planned Investigatirs will check all entered data into the registry with the predefined ranges. The database is protected against any inconsistency and incorrect entering by the strictly predefined range in all fields. Instead of that, data checks will be performed yearly.

During the site monitoring data verification of the transfer from source documents to the database will be performed.

Iiverstigators have data dictionary, which includes descriptions of each variable and, if relevant, normal ranges.

Investigators use standard local operation procedures for any activities during the registry (as patient recruitment, data collection and management, data analysis) and local authorities approve all of those procedures.

Investigators calculated the sample size for demonstration of hypothesis of the registry.

Descriptive analysis of the data will be reported using basic summary statistics. Results will be summarized for the whole group and for the diagnostic subgroups. P-values and confidence intervals will be 2-sided, and statistical significance will be declared at the 2-sided 0,05-level. For continuous variables mean values, standard deviations, 95% confidence intervals, median and lower and upper percentiles, as well as minimum and maximum values will be calculated.

Safety is assessed by reports of AEs with relation, seriousness, action taken, and outcome. AEs are summarized using the MedDRA coding system. Event rates for single AEs are calculated based on the total number of documented patients. AEs are categorized according to relation, seriousness and outcome. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
