Study of Oral PG-116800 Following a Heart Attack

Heart attacks cause damage to heart muscle that can weaken the heart and lead to changes in the shape and pumping ability of the heart. These changes can lead to heart failure. An enzyme called metalloproteinase (MMP) plays a role in this damage. The main purpose of the study is to test whether a possible new drug (called PG-116800) that interferes with the MMP enzyme can prevent some of the damage to heart muscle in patients who have had a heart attack. The study will also...

Use of Adult Autologous Stem Cells in Treating People 2 to 3 Weeks After Having a Heart Attack (The Late TIME Study)

More than 1 million Americans suffer heart attacks each year. Although current treatments are able to stabilize the condition of the heart, none is able to restore heart function as it was prior to the heart attack. Adult stem cells, which are immature cells that can become many different types of cells, may offer a potential means of reversing or preventing permanent damage caused by a heart attack. Recent studies have shown promise in using adult stem cells from bone marrow t...

Wiser Choices in Acute Myocardial Infarction

Patients who are hospitalized because of a heart attack are prescribed a number of medicines to help the heart heal. The investigators will examine different ways in which clinicians share information about those treatment options with patients and the impact that this can have on patients' choices and health.


Pre-hospital Administration of Thrombolytic Therapy With Urgent Culprit Artery Revascularization

The PATCAR study has been designed to test the hypothesis that the strategy of pre-hospital use of a "clot busting" (thrombolytic) drug followed with emergent heart catheterization including stenting of the problematic coronary artery, will result in a lower mortality and reduced repeat heart attack rates. Early identifying and treating heart attacks patients prior to the arriving at the hospital, in those patients who qualify for the "clot busting" drugs will lower the size o...

Mesenchymal Stem Cells and Myocardial Ischemia

Ischemic cardiomyopathies are a leading cause of death in both men and women. When a person has a heart attack, blood is unable to reach a certain area of the heart, and if the blood supply is not re-established quickly, that area of the heart can suffer permanent damage. While recovery from a heart attack can be managed through medications and lifestyle changes, these treatments can not reverse the all damage to the heart. Current research is focusing on the development of cel...

Revascularization StrategIes for ST Elevation Myocardial Infarction Trial

This study is being conducted in patients with a major heart attack caused by a blocked artery undergoing Percutaneous Coronary Intervention (PCI) to open up the blockage. Up to 50% of people with an heart attack are found to have one or more additional narrowings that did not cause the heart attack. At present the best way to manage these additional blockages is not known. Many cardiologist recommend opening these blockages at at a later time after the heart attack. The presen...

Safety of TG100-115 for Heart Attack Treated With Angioplasty

TG100-115 is able to reduce the size of heart attacks in pre-clinical models. The hypothesis of this study is that TG100-115 can be given safely to patients who suffer a heart attack and undergo angioplasty to restore blood flow. We will also evaluate whether TG100-115 reduces heart muscle damage.

Bone Marrow Stem Cell Infusion Following a Heart Attack

The goal of this study is to determine the safety of giving a patient's own bone marrow-derived stem cells delivered with a catheter (tube) into the coronary arteries (blood vessels of the heart). Stem cells are simple cells produced by the bone marrow that can develop into many types of cells. It is possible that these cells will decrease the size of damage caused to the heart from a heart attack and increase the pumping efficiency of the heart; which can be decreased due to...

Examining Heart Attacks in Young Women

Heart disease and heart attacks pose a serious health risk to young women, and women tend to experience less successful recoveries after a heart attack than men do. This study will examine various factors that may predispose women to heart attacks and to poor recovery after a heart attack. The differences between men and women in the medical care that they receive following a heart attack will also be studied.

Troponin in Acute Chest Pain to Risk Stratify and Guide EffecTive Use of Computed Tomography Coronary Angiography

Most patients presenting to hospital with symptoms of a heart attack are sent home without further tests once a heart attack has been ruled out. Current strategies to assess patients with a suspected heart attack involve blood tests to measure troponin, a protein released into the bloodstream when the heart muscle is damaged. Despite having had a heart attack ruled-out, some patients have unrecognised heart disease and are at risk of having a heart attack in the future. Howeve...

Post-Conditioning to Reduce Infarct Size

When angioplasty (PTCA) and stenting of the blood vessels of the heart is the treatment for a Heart Attack, there is damage to the heart muscle that is caused by the sudden opening of the blood vessels. This is called "reperfusion injury". The cell death is due to inflammation and the generation of free radicals. The primary objective of this study is to determine if post-conditioning(four brief (30 second) PTCA balloon inflations) reduces damage to the heart muscle. This will...

Novel Method to Diagnose Acute Myocardial Ischemia

The aim of this study is to improve the detection of heart attack in people who come to a hospital emergency room (ER) with cardiac symptoms. We are testing a novel technology that calculates the heart's electrical activity at points all around the upper body torso and develops a map showing areas indicating heart attack. Our hypothesis is that this new body mapping technique will be better than the standard electrocardiogram (ECG) in detecting heart attack.

A Study of Low-dose Intracoronary Thrombolytic Therapy in STEMI (Heart Attack) Patients.

Heart attacks are caused by a blood clot blocking the blood vessels of the heart, preventing blood getting to the heart muscle. Opening up the artery with a balloon (angioplasty) and a small mesh tube (stent) although life saving can cause this clot to break up and get washed downstream, which can make the heart attack worse. The investigators can measure the amount of damage caused to the microcirculation by calculating the IMR (Index of Microcirculatory resistance). Th...

CArdiosphere-Derived aUtologous Stem CElls to Reverse ventricUlar dySfunction

The purpose of this study is to determine whether giving cardiosphere-derived stem cells (CDCs) to patients with decreased heart function and/or a large amount of damaged muscle after a heart attack is safe. CDCs are cells grown from small biopsy samples taken from the heart. Giving a patient their own CDCs is an investigational procedure that has been approved by the Food and Drug Administration for this study. In addition to determining whether this treatment is safe, the stu...

Use of Adult Autologous Stem Cells in Treating People Who Have Had a Heart Attack (The TIME Study)

Heart attacks are a leading cause of death for both men and women in the United States. A heart attack occurs when blood flow to the heart is restricted, commonly due to a blood clot that has formed in one of the coronary arteries. If the clot becomes large enough, blood flow to the heart can be blocked almost completely and the heart muscle in that area can suffer permanent injury or death. Although a percutaneous coronary intervention (PCI) can be used to open up the blocked ...

Angioplasty and Heart Stents to Treat Individuals With an Occluded Artery Following a Heart Attack

The purpose of this study is to evaluate arterial patency and left ventricular ejection fraction by examining angiographic data one year following a heart attack and treatment with late revascularization.

Cardiac MRI for Patients Enrolled in INFUSE-AMI

Background: - INFUSE AMI is an ongoing clinical trial examining how patients with heart attacks are treated. The study's aim is to help determine the best way to treat patients with specific kinds of heart attacks caused by blood clots. - To evaluate the effect of the heart attack on the heart tissue and function, participants in the INFUSE-AMI study will have magnetic resonance imaging (MRI) scans of the heart at specific times after their hea...

Balloon Catheters and Stents to Prevent Heart Rhythm Irregularities in Individuals Post-Heart Attack

The purpose of this study is to determine if opening blocked arteries with heart balloons and stents prevents heart rhythm problems in individuals 3 to 28 days after a heart attack.

Doxycycline to Protect Heart Muscle After Heart Attacks

Current medical treatment allows more people to survive heart attacks than in the past. However, some of the survivors suffer heart disease and require hospitalization later on. The causes behind this heart disease (heart failure) after a heart attack are poorly understood. Matrix metalloproteinase 2 (MMP-2) is a protein that cuts other proteins into pieces, and is activated in heart muscle when there is a heart attack. MMP-2 causes heart injury when the blood flow to the hear...

Platelet Function Monitoring in Patients Treated With Clopidogrel at the Time of Primary Percutaneous Coronary Angioplasty

Platelets are a major component of clot formation which can lead to clotting events such as heart attack. During treatment for a heart attack, doctors try to remove this blockage as quickly as possible so that the heart can recover and start to work properly again. The standard of care at the Heart Institute for patients having a heart attack is a procedure called a Percutaneous Coronary Angioplasty. A drug called Clopidogrel (Plavix) is routinely used prior to the angioplast...

Distribution of Highly Sensitive Troponin in the Critically Unwell & Associated Mortality

The current diagnostic criteria for a heart attack require evaluation of a patient's symptoms and ECG but importantly a blood test called troponin. With advancing technology this test has become more sensitive and is now called a high sensitivity troponin. This is a very effective way of rapidly excluding a heart attack if the test is negative. However there are a number of causes of a raised high sensitivity other than a heart attack, particularly critical illness states. In t...

Study of Women With Acute Coronary Syndromes and Nonobstructive Coronary Artery Disease

Approximately 600,000 women are treated for acute coronary syndrome (ACS) annually in the US. ACS includes heart attack and a milder form called unstable angina. Many of these women have angiograms of which 14-39% show no "significant" coronary artery disease (CAD, cholesterol plaque accumulation in arteries of the heart). The remaining majority of women with ACS have cholesterol plaque buildup which appears severe enough on angiography to limit blood flow to the heart. ...

Bivalirudin Infusion for Ventricular Infarction Limitation

The purpose of this study is to evaluate whether the use of bivalirudin will reduce extent of the damage done to the heart muscle in patients who suffered a heart attack, compared to the comparator treatment (heparin).

Assessment of Noninvasive Methods to Identify Patients at Risk of Serious Arrhythmias After a Heart Attack

This study evaluates the usefulness of noninvasive tests of the structure of the heart and the nervous system controlling the heart. It will assess whether combining tests that evaluate heart structure with others that measure the nervous system controlling the heart will identify most patients who develop serious heart rhythm problems after a heart attack.

Safety and Efficacy on Cell-Based Therapy in Patients With Recent Large Acute Myocardial Infarction

The purpose of this study is to test bone marrow mononuclear cells for patients with recent heart attack who are at high risk of experiencing heart failure. This study drug is made of you own cells. Studies similar to this one have suggested that the use of cell-based transfer after heart attack can improve the recuperation of the heart. The purpose of this study is to assess whether cell transfer can improve the healing of the heart after a heart attack.
