About this study
Official title: Assessment of Relationship Between Acute Ischemic Stroke and Heart Disease
Although cardio-embolic etiology of ischemic stroke (IS) is largely respected, there is still no clear recommendation for routine complex cardiological examination in all IS patients. Using complex cardiological examination the investigators expect:
- more accurate detection of patients with concomitant heart disease (cardiac rhythm disorder, valve disorders, acute coronary syndrome, cardiac thrombus and myxoma, atrial and ventricle septum defects)
- higher number of etiologically determinated IS, which is crucial for accurate secondary prevention.
Read the detailed description
The investigators expect significant changes of biochemical parameters (NT pro B-type of natriuretic peptide, pro-atrial natriuretic peptide, creatinkinase MB, troponin T), inflammatory markers (interleukine 6, procalcitonin, high sensitive C-reactive protein), and coagulation parameters in patients with CE IS compared to other causes of IS.
Assessing the glomerular filtration of cystatin C, glycated haemoglobin and serum lipids and its correlation with prior medicament use will allow to evaluate the long-term compensation of arterial hypertension, diabetes mellitus and dyslipidemia in IS patients.
In addition to the above mentioned comprehensive cardiological examinations, 1- and 3-week ECG-Holter will be performed in subpopulation of patients old up to 50 years and with cryptogenic ischemic stroke in the period from 1st May 2013 to 31st December 2015. These patients will also fill in a special epidemiologic questionnaire. Anticipated enrollment in this substudy of HISTORY study is 40 - 80 patients.
In selected young cryptogenic stroke patients, a subcutaneous cardiac monitor was implanted for the detection of paroxysmal atrial fibrillation in the period from 1st January 2014 to 31st December 2015.
From 2016 in young ischemic stroke (IS) patients under 50 years, a standard perfusion/ventilation scintigraphy of lungs will be performed to exclude acute pulmonary embolization (coincidental) in case of elevated serum D-dimers after admission.
In all enrolled young IS patients, a BP Holter will be performed after the discharge home to exclude possible arterial hypertension, which did not presented during hospitalization.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Acute Ischemic Stroke | Patients with acute ischemic stroke admitted within 12 hours after onset. |
What is being measured
The primary outcome is the main question the study is designed to answer.
To assess the serum level profile of cardiac troponin T (cTnT) in acute ischemic stroke (AIS) patients and to evaluate factors associated with increased serum level of cTnT.
Measured: Within 12 hours after ischemic stroke onset.
Secondary outcomes (1)
Correlation between location and volume of brain infarction.
Measured: At admission within 12 hours after stroke onset and after 24hours.

Questions about this trial
What is this clinical trial studying?
An observational study of Brain Ischemia and Acute Stroke, run by University Hospital Olomouc at 1 site in Czechia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 1 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Czechia. 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. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Michal Kral, MD (+420 604 171 594, michal.kral@fnol.cz), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To assess the serum level profile of cardiac troponin T (cTnT) in acute ischemic stroke (AIS) patients and to evaluate factors associated with increased serum level of cTnT. (time frame: Within 12 hours after ischemic stroke onset.). 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 NCT01541163, which also lists 9 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 1 Nov 2017.
