MYOCARDIAL ISCHEMIA

This study tests a new device called Freesolve, a temporary magnesium scaffold that props open blocked heart arteries and then dissolves over time. About 1,859 people with up to two new blockages will receive either this scaffold or a standard permanent stent. The goal is to see …

This early study tests a device called the A-FLUX Reducer, which is implanted into a vein in the heart to help blood flow. It is for people with chest pain caused by problems in the heart's tiny blood vessels (microvascular dysfunction). The study will enroll 30 adults and focus …

This study tests whether using a CT scan to guide heart stent placement is better than the current standard (IVUS ultrasound) for people with hardened, calcified coronary arteries. About 700 adults with evidence of reduced blood flow to the heart will be randomly assigned to one …

This study looks at whether taking just one blood thinner (single antiplatelet therapy) is safer and as effective as taking two (dual antiplatelet therapy) in older adults or those at high risk of bleeding who have had a balloon procedure to open blocked heart arteries. About 576…

This study is tracking 2,000 people with coronary artery disease who receive either a Synergy XD or Synergy Megatron stent during a routine procedure to open blocked heart arteries. Researchers want to see how these stents perform in everyday medical practice compared to other dr…

This study tests a new type of heart stent made from magnesium that slowly dissolves over time. It is designed for people with long blockages in their heart arteries. The goal is to see if the stent is safe and works well at keeping arteries open for up to 12 months. About 100 pa…

This study compares a new type of heart stent called Freesolve, which is made of magnesium and dissolves over time, to a standard permanent metal stent. About 1,859 people with coronary artery disease will receive one of the two stents. The goal is to see if the dissolving stent …

This study tests whether adding a simple breathing exercise (inspiratory muscle training) to standard cardiac rehab helps people with narrowed heart arteries recover better. 72 adults who had a heart procedure (angioplasty) will be split into two groups: one does standard rehab, …

This study tests whether a magnetocardiography (MCG) device can detect reduced blood flow to the heart muscle in people with acute chest pain but no major artery blockages. About 3,786 participants will undergo MCG scanning, and results will be compared to a standard ultrasound t…

This study tests a new computer program that helps doctors diagnose blocked heart arteries more accurately using CT scans. The software combines several checks into one step, which may reduce the need for invasive procedures like heart catheterization. Researchers will look at pa…

This study aims to improve how doctors diagnose a rare heart condition where a coronary artery starts in the wrong place (AAOCA), which can cause sudden cardiac death in young athletes. Researchers will use artificial intelligence and 3D computer models to analyze CT scans and pr…

This study is testing a new smartphone-connected 12-lead ECG device to see if it can accurately diagnose heart attacks (STEMI and NSTEMI) in people with chest pain. Researchers will compare the smartphone ECG readings to standard hospital ECGs in 1000 adults. The goal is to valid…

This observational study will enroll 10,000 adults who are already scheduled for a cardiac CT scan. Researchers will use artificial intelligence to analyze the scans, looking for subtle signs of dangerous plaque that might predict future heart attacks. Participants will also give…

This study is testing a drug called regadenoson in children who need a special heart MRI. The drug helps doctors see how well blood flows to the heart during a stress test. Researchers want to find the right dose and make sure it is safe for kids of different ages, from infants t…

This study looks at 570 people with chronic coronary syndrome (chest pain or shortness of breath due to narrowed heart arteries). Participants with abnormal blood flow on a PET scan will be randomly assigned to either immediate heart catheterization or a 3-month delay, while both…

This study is checking if a blood test called high-sensitive troponin I can detect heart damage in people having leg surgery with a nerve block. Researchers will measure troponin levels during surgery and at 24 and 48 hours after. The goal is to see if this test can help predict …

This study is tracking 1,000 adults with psoriasis to see how their skin condition relates to heart disease. Researchers will use blood tests and heart imaging to find early signs of heart problems. The goal is to better understand why people with psoriasis have higher rates of h…

This study looks at how modern, minimally invasive lung cancer surgery affects the heart's electrical signals. Researchers will monitor 100 adults before, during, and after surgery to see if temporary changes occur. The goal is to better understand the heart stress caused by the …
