Plain English Summary

Background and study aims
Chronic heart failure is currently the most frequent cause of hospitalization in Germany. Despite being treated with a wide range of drugs known as beta-blockers, many heart failure patients still have insufficient heart rate reduction. Heart failure patients should generally be controlled for heart rate as it is an important risk factor for cardiovascular death. The aims of this study is to observe the effects of Procoralan®, a drug that specifically reduces heart rate, on heart failure symptoms, heart rate reduction and quality of life in patients with chronic stable heart failure under daily routine. We also intend to assess how safe and tolerated this drug is.

Who can participate?
Ambulatory patients (who can walk), with no age and gender limitation, with stable chronic heart failure and resting heart rate ≥ 75 beats per minute, who have been prescribed Procoralan® before entering the study.

What does the study involve?
All patients involved in the study will be treated with Procoralan®. They will be asked to come to follow up visits after four weeks and then after another three months. During these visits a routine practice investigation will be carried out and a case report form regarding heart failure, co-medications and other diseases will be filled out by the doctor. The patients will be asked to fill out the patient quality of life questionnaire (EQ-5D) at each visit. According to heart rate reduction, the dosage of Procoralan® can be adapted at the first follow-up visit (week 4). Patients will be included in the study for four months.

What are the possible benefits and risks of participating?
There are no particular benefits or risks. The treatment given to the patient corresponds to the daily routine. Patients are free to withdraw from the study at any time without giving a particular reason.

Where is the study run from?
It is planned that the study will be carried out by approximately 1000 cardiologists and internists (practice-based or in outpatient clinics) across the Germany. There is no lead center.

When is the study starting and how long is it expected to run for?
The study starts on 19th April 2012 and lasts until 31st December 2012. The recruitment of participants runs until 31st July 2012.

Who is funding the study?
The funder and the sponsor of the study is Servier Deutschland, GmbH.

Chronic stable systolic heart insufficiency


Observational study to get information about therapy of chronic systolic heart insufficiency with Procoralan®; under daily routine practice by cardiologists, internists and general practitioners.

The diagnosis of angina will be confirmed by trialists at baseline. After the baseline visit, there is a visit after 4 weeks and the final visit after 4 months.
