Mindful Movement Intervention for Post-MI Patients

Myocardial Infarction

This study evaluates the feasibility and acceptability of a 12-week Tai Chi intervention for patients who have recently had a heart attack and are not participating in a standard cardiac rehabilitation program. Half of the 75 patients will be randomly assigned to the Tai Chi condition and the other half will be assigned to 12 weeks of Health Education. In addition to examining feasibility and acceptability, the investigators will evaluate the impact of participation in the Tai Chi condition on measures of cardiac health, physical function, self-reported health behaviors, and mental health as compared to Health Education within the context of this developmental/exploratory study.

T2 Heart Mapping in AMI Population for the Prediction of Short Term Major Adverse Cardiovascular...

Myocardial InfarctionAcute

A novel Cardiac MRI sequence, developed by Dr. Maria Altbach (Double Inversion radial fast Spin Echo T2 mapping), has been tested clinically. It demonstrated a high sensitivity to the heart muscle swelling ("edema") in different types of heart injury, including heart attacks. The investigators propose to use T2-Map methodology in patients with acute heart attacks and to compare value of this method with other clinical and imaging parameters in predicting short-term (30 day) clinical outcomes of these patients. If successful, the project will provide an effective risk-stratification tool to identify patients with heart attack as a result of atherosclerotic disease, who require more aggressive therapeutic approach and closer follow-up after initial hospitalization.

Pan-Cardio-Genetics Clot Assessment in Acute Coronary Syndromes

STEMI - ST Elevation Myocardial InfarctionThrombi1 more

Acute myocardial infarction with ST elevation (STEMI) is one of the leading causes of mortality. Although the presence of thrombus in STEMI patients has been linked to adverse outcomes, routine thrombus aspiration has not been proven effective. A potential explanation could be that patients with STEMI should be risk-stratified. Thus, a more personalized approach in treating these patients is stressfully required. This proposal aims to establish the required interdisciplinary infrastructure for developing a risk-stratification model by implementing clinical, laboratory and angiographic data with molecular knowledge obtained by using innovative technologies, such as data from nano/micro-Computed tomography and circulating microRNAs. Two hundred consecutive patients with STEMI undergoing thrombus aspiration will be enrolled in the study and will be followed-up for one year for Major Adverse Cardiac and Cerebrovascular events (MACCE). The proposed approach will shed light on the pathophysiological mechanisms and broaden the investigator's understanding of the complex cellular and molecular interactions in the STEMI setting that, along with clinical parameters, affect patient outcomes. Furthermore, it will enable the identification of certain circulating micro-RNAs as cardiovascular disease biomarkers and it will help clinicians to better stratify the cardiovascular and cerebrovascular risk of patients with STEMI. As part of the work, important characteristics of aspirated thrombi will be assessed for the first time (such as volume, density and shape) and will be linked to patient outcomes. All this information will be incorporated into one in-vitro model, which will be developed using bioprinting and microfluidics methodologies. The in-vitro model will facilitate: (i) the in-depth exploration of the pathophysiological mechanisms in patients with STEMI; and (ii) the therapeutic optimization of innovative nanocarriers/nanomedicines with thrombolytic efficacy. Clearly, the study improves personalized cardiovascular medicine approaches, by considering individual patient clinical assessment in a way that empowers the precision in diagnosis and therapy.

Biomarkers for Postoperative Myocardial Infarction in Cardiac Surgery.

Myocardial Infarction

Myocardial infarction and subsequent myocardial injury after cardiac surgery occurs in 7-15% of patients undergoing cardiac surgery and is associated with an increased length of stay, and reduced short- and long-term survival. Cardiac troponin is considered to be a cornerstone in the diagnosis of a myocardial infarction. Heart-type Fatty Acid-Binding Protein (H-FABP) is a new sensitive biomarker for myocardial injury. The effectiveness of using the combination of H-FABP with Troponin to diagnose myocardial injury within 6 hours after the onset of ischemia is well reported. Previous studies in non-surgical patients have associated increased H-FABP with an increased risk of subsequent death and major cardiac events. The prognostic value in cardiac surgery patients has not been studied extensively. The objective is to estimate the association between biomarkers of myocardial injury and myocardial infarction in patients undergoing cardiac surgery. Myocardial infarction will be established with both a new and very early marker of myocardial injury (Heart-type Fatty Acid Binding Proteins) as well as to a known early marker of such injury (Cardiac troponin).

Efficacy of Preoperative Electrocardiography

Acute Coronary SyndromeMyocardial Infarction1 more

A preoperative electrocardiogram (ECG) is nearly routinely performed by anesthesiologists in elderly non-cardiac surgery patients as part of pre-anesthesia evaluation. However, the added value of this routine ECG beyond patient history and physical examination is questionable. The ECGtrial will investigate the efficacy of routine preoperative electrocardiography in patients undergoing non-cardiac surgery.

Analyzing Gene Regions That May Interact With the Effectiveness of High Blood Pressure Drugs

Myocardial InfarctionCerebrovascular Accident3 more

High blood pressure is one of the most common health problems in the United States. There are many drug treatment options for high blood pressure, but these medications are not always effective. People with treated high blood pressure can still suffer from other serious cardiovascular health problems, including heart attack, sudden death, or stroke. Genetic variations may cause some people to be more susceptible to these cardiovascular outcomes despite treatment. This study will identify new gene regions that may influence the effectiveness of high blood pressure drugs in preventing the above mentioned cardiovascular conditions.

Facilitating Catheter Guidance to Optimal Site for VT Ablation

Post-myocardial Infarction Ventricular Tachycardia

Each year in the UK, approximately 150,000 people have a heart attack when the blood supply to their heart is compromised. As a result, affected regions of the heart can become diseased and scarred. In a healthy person, electrical waves propagate across the heart in a regulated pattern which triggers contraction to pump blood around the body. The scar tissue that forms as a result of a heart attack can disrupt the propagation of the electrical waves. If significant disruptions occur, blood cannot be pumped out of the body effectively, leading to sudden death. Ablation therapy aims to eliminate areas of diseased tissue that cause disruption to the heart rhythm, by applying radiofrequency using catheters inserted into the heart. The most accurate techniques used to locate the region to ablate require the induction of dangerous heart rhythms, which are only inducible in about 65% of people. Pace mapping is a technique used to locate regions to ablate, which can be performed during normal heart rhythm. ECG data, which records electrical signals from the heart, is collected when the patient has an abnormal heart rhythm. From this template ECG, a clinician can tell the approximate location of the diseased tissue. A catheter is directed to that location, the heart stimulated, and another ECG, called the paced ECG is recorded. If the paced ECG matches the template ECG, it is assumed that the heart was paced in the location that requires ablation. Current ablation techniques are difficult, time consuming, and inaccurate. As a result, the procedure may work in only half of all patients, and result in unnecessary damage to healthy tissue, leading to later impairment of heart function. The CPS project's overall goal is to increase the success rates of ablation therapy by improving the accuracy and efficiency of locating the optimal region of tissue to eliminate during the pace mapping procedure. Increasing ablation therapy success rates will mean that patients will be unlikely to suffer from future heart rhythm disorders as a result of their heart attack, increasing the life expectancy of heart attack patients. Excess damage caused to the heart as a result of unnecessary ablation lesions will be limited, decreasing the likelihood of future complications. In addition, dangerous heart rhythms do not need to be induced in the patient, significantly decreasing the risk of death during the treatment.
