About this study
Official title: Study of the Efficacy, Safety and Tolerability of Low Molecular Weight Heparin vs. Unfractionated Heparin as Bridging Therapy in Patients With Embolic Stroke Due to Atrial Fibrillation
Patients with Atrial fibrillation (AF) make a unique group of ischemic stroke, mostly caused by emboli from the left atrial appendage. Oral anticoagulation (Warfarin) is recommended for prevention of recurrent embolic stroke but it takes several days to reach a therapeutic international normalized ratio (INR : 2.5) so bridging therapy with a short acting intravenous anticoagulant is recommended until therapeutic INR level is reached. A common strategy is to use intravenous unfractionated heparin (UFH) until a standard activated partial thromboplastin time (aPTT) is reached and then initiating warfarin. Another strategy is to use subcutaneous (SQ) injection of a low-molecular-weight heparin (LMWH) eg. Enoxaparin.
The investigators will compare LMWH and UFH, focusing on risk of new stroke and mortality rate.

METHOD: This study is randomized controlled trial that will be performed in 80 patients ages between 18 and 75 with confirmed acute ischemic stroke purely due to AF who will be hospitalized in Shiraz Medical University affiliated teaching hospitals. Patients will be randomly assigned in two groups. A brain CT will be done to confirm the absence of intracranial hemorrhage and to assess the size of cerebral ischemia.
First group will receive 1 mg of enoxaparin (Clexane, Sanofi, Paris) per kilogram of body weight SQ every 12 hour with warfarin 5mg orally everyday and both drugs will be continued until the target INR level (2.5) is reached then clexane will be discontinued.
The second group will receive continuous UFH infusion 1000 unit per hour and then the dose will be adjusted to maintain a therapeutic aPTT (two times to baseline) level then warfarin will be started (5 mg everyday).
The investigators will follow patients in both groups until target INR will be achieved (2.5) and after that clexane and UFH will be discontinued. Adverse events will be assessed in both groups for three months.
Data will be analyzed with Statistical Package for the Social Sciences (SPSS) version 15 and Chi-square statistics.
Main outcome of our study will be evaluation of new stroke, mortality, central nervous system (CNS) hemorrhage, major bleeding, drop out and other unwanted side effects in first week and three months after stroke.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EnoxaparinDrug
Also called clexane (Clexane, Sanofi, Paris)
1 mg of enoxaparin per kilogram of body weight subcutaneous every 12 hour
HeparinDrug
Also called Heparin Sodium (Alborz Darou,Tehran)

| Study group | Role | What they receive |
|---|---|---|
| Low molecular-weight heparin | Experimental | these patients will receive 1 mg of enoxaparin (clexane) per kilogram of body weight subcutaneous every 12 hour with warfarin 5mg QD and both drugs will be continued until the target INR level (2.5) is reached then clexane will be discontinued. Receives: Drug: Enoxaparin |
| unfractionated heparin | Active comparator | This group will receive continuous intravenous unfractionated heparin sodium infusion 1000 unit per hour initially and then the dose will be adjusted to maintain a therapeutic aPTT level (two times to baseline) then warfarin will be started (5 mg QD).

What is being measured
The primary outcome is the main question the study is designed to answer.
mortality
all death cases are included but only mortality due to cerebrovascular accident are considered.
Measured: up to the 3 months of follow-up
ischemic stroke
Ischemic strokes are those that are caused by interruption of the blood supply
Measured: up to the 3 months of follow-up
hemorrhagic stroke
hemorrhagic strokes are the ones which result from rupture of a blood vessel or an abnormal vascular structure.
Measured: up to the 3 months of follow-up
Secondary outcomes (5)
symptomatic CNS hemorrhage
Intracranial bleeding occurs when a blood vessel within the skull is ruptured or leaks that causes neurological symptoms. It can result from nontraumatic causes as occurs in hemorrhagic stroke such as a ruptured aneurysm. Anticoagulant therapy can heighten the risk that an intracranial hemorrhage will occur.
Measured: up to the 3 months of follow-up
Non-CNS hemorrhage
any bleeding of other sites of body except CNS.
Measured: up to the 3 months of follow-up
asymptomatic CNS_hemorrhage
Intracranial bleeding occurs when a blood vessel within the skull is ruptured or leaks that will not cause neurological symptoms. It can result from nontraumatic causes as occurs in hemorrhagic stroke such as a ruptured aneurysm. Anticoagulant therapy can heighten the risk that an intracranial hemorrhage will occur.
Measured: up to the 3 months of follow-up
time to reach target INR
the therapeutic INR level for patients on warfarin therapy is between 2.0 to 3.0.
Measured: average time 7 to 10 days (it is variable between individuals)
tolerability of drugs
tolerability is how a patient can tolerate heparin and LMWH in terms of side effect and route of administration.
Measured: participants will be followed for the duration of hospital stay, an expected average of 1 week

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Patients with Atrial fibrillation (AF) make a unique group of ischemic stroke, mostly caused by emboli from the left atrial appendage. Oral anticoagulation (Warfarin) is recommended for prevention of recurrent embolic stroke but it takes several days to reach a therapeutic international normalized ratio (INR : 2.5) so bridging therapy with a short acting intravenous anticoagulant is recommended until therapeutic INR level is reached. A common strategy is to use intravenous unfractionated heparin (UFH) until a standard activated partial thromboplastin time (aPTT) is reached and then initiating warfarin. Another strategy is to use subcutaneous (SQ) injection of a low-molecular-weight heparin (LMWH) eg. Enoxaparin.
The investigators will compare LMWH and UFH, focusing on risk of new stroke and mortality rate.
METHOD: This study is randomized controlled trial that will be performed in 80 patients ages between 18 and 75 with confirmed acute ischemic stroke purely due to AF who will be hospitalized in Shiraz Medical University affiliated teaching hospitals. Patients will be randomly assigned in two groups. A brain CT will be done to confirm the absence of intracranial hemorrhage and to assess the size of cerebral ischemia.
First group will receive 1 mg of enoxaparin (Clexane, Sanofi, Paris) per kilogram of body weight SQ every 12 hour with warfarin 5mg orally everyday and both drugs will be continued until the target INR level (2.5) is reached then clexane will be discontinued.
The second group will receive continuous UFH infusion 1000 unit per hour and then the dose will be adjusted to maintain a therapeutic aPTT (two times to baseline) level then warfarin will be started (5 mg everyday).
The investigators will follow patients in both groups until target INR will be achieved (2.5) and after that clexane and UFH will be discontinued. Adverse events will be assessed in both groups for three months.
Data will be analyzed with Statistical Package for the Social Sciences (SPSS) version 15 and Chi-square statistics.
Main outcome of our study will be evaluation of new stroke, mortality, central nervous system (CNS) hemorrhage, major bleeding, drop out and other unwanted side effects in first week and three months after stroke.
