About this study

Official title: Coronary ARteriogenesis With Combined Heparin and EXercise Therapy in Chronic Refractory Angina

This study evaluates the addition of heparin to a 2-week cycle of physical rehabilitation in the treatment of refractory angina. Half of the patients will undergo heparin-primed physical rehabilitation, while the other half will undergo only physical rehabilitation.

Read the detailed description

Our approach is based on the combination of pharmacological stimuli (with heparin) on top of a 2-week cycle of physical rehabilitation. The rationale for this chemical-physical cocktail stems from the fact that increase in shear stress (achieved with exercise), or heparin (when used alone) have no significant effect on coronary arteriogenesis. Nevertheless, when the two stimuli are coupled coronary arteriogenesis is consistently present, and clinically significant.

The basic principle of heparin treatment is to potentiates angiogenic growth factors, which are over expressed by increased shear stress at the site of pre-existing collateral vessels as a result of exercise or pacing. Although the precise mechanisms by which heparin potentiates arteriogenesis remain to be completely elucidated, heparin administration combined with exercise has great potential in treating patients with effort angina who are not indicated for conventional revascularization therapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from Baseline Canadian Cardiovascular Society (CCS) angina severity class at 2 weeks

    CCS class ranging from 1 (mild) to 4 (severe) before and after the 2-week physical rehabilitation.

    Measured: 2 weeks

Secondary outcomes (2)
  1. Change from Baseline peak stress wall motion score index (WMSI) at 2 weeks

    Peak WMSI at stress echocardiography before and after 2-week physical rehabilitation at . Wall motion score index is assessed by using 17- segment model of left ventricle (1=normal, 4=dyskinetic).

    Measured: 2 weeks

  2. Change from baseline peak stress global longitudinal strain (GLS) at 2 weeks

    Peak stress GLS assessed by echocardiography before and after the 2-week physical rehabilitation.

    Measured: 2 weeks

The record lists 1 site in Serbia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from Baseline Canadian Cardiovascular Society (CCS) angina severity class at 2 weeks (time frame: 2 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03350737, which also lists 18 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 May 2020.
