Patients who present to MUSC's Chest Pain Center with acute chest pain and have undergone coronary computerized tomography angiography or triple rule-out computed tomography imaging showing an intermediate stenosis will be prospectively selected. Consented patients will then have their clinical indicated coronary computerized tomography angiography or triple rule-out computed tomography imaging undergo an expedited computed tomography-fractional flow reserve analysis analysis. This analysis will be provided to Chest Pain Center physician of record to aid in downstream patient treatment decision making. Patients will then be followed-up at 3-months via telephone call and electronic medical records review.
The purpose of the study is to generate a bio bank of specimens for research. We will tissue that would otherwise be discarded from clinical or surgical procedure and information from medical records. We will also collect discarded blood, urines and sputum. Collecting samples will help to better understanding the mechanisms of cardiovascular diseases, identify biomarkers for early diagnosis and to predict safety and efficacy of new therapies.
The purpose of this study is to test if LCZ696 taken twice a day, compared to ramipril taken twice a day, is safe and effective in reducing complications following an acute myocardial infarction (post-AMI), such as death from cardiovascular (CV) causes, hospitalization for heart failure (HF), or outpatient HF.
LCZ696 is a medicine which has been approved by the US Food and Drug Administration (FDA) for the treatment of people with chronic heart failure (NYHA Class II-IV) and reduced ejection fraction. It has not been approved for treatment following a heart attack, the medical condition that you have. The medicine being tested in this study is not currently available for patients with your medical condition to receive a prescription for and/or to buy in any country. To date, over 21,000 subjects have taken LCZ696 in studies that have been performed in healthy subjects and patients with hypertension, heart failure with reduced ejection fraction, and heart failure with preserved ejection fraction.
The other medicine in this study, also called the comparator drug, is ramipril which is currently available on the market and approved for the treatment of patients with clinical signs of congestive heart failure post-AMI. Ramipril belongs to a class of medications called angiotensin-converting enzyme inhibitors, or ACE inhibitors (ACEIs), recommended as standard -of- care to treat the post-AMI patients.
Current care patterns for patients with acute chest pain fail to provide optimal quality and value. To avoid missing acute
coronary syndrome (ACS), emergency physicians hospitalize >50% of patients who present to the Emergency Department with
chest pain. However, s success with the HEART Pathway, the next logical step is regional dissemination.
This project will leverage Carolinas Collaborative infrastructure to collect data specific to the HEART Pathway from all 4 health
systems, establishing rates of healthcare utilization and ACS outcomes for Emergency Department patients with chest pain in
the Carolinas. In addition, we will engage key stakeholders at each health system to develop an implementation strategy. This
proposal builds on our prior work and will provide pilot data essential for a larger grant application that will support rigorous
testing and implementation of the HEART Pathway across Carolinas Collaborative health systems.
