Tests a targeted plan for people with chest pain from heart artery disease
This study aims to match people with angina (chest pain from heart artery problems) to the most helpful treatment plan based on their test results. It’s done around the time doctors are planning an invasive heart scan to look at the coronary arteries.
CorkAges 18 years+ - NCT04827498Recruiting
Testing heart blood-flow problems without clogged arteries
This study looks at how well the heart’s blood vessels work in people who have symptoms of reduced blood flow but no major artery blockage. It uses special heart tests with medicines to check how the vessels respond and may help guide better diagnosis and treatment.
MadridAges 18 years+ - NCT05178914Recruiting
Testing heart pain treatment guided by blood-flow measurements
This study looks at how to personalize treatment for people with angina (chest pain) by measuring how well blood flows through the heart’s small vessels and the main arteries during a procedure. It may help doctors choose the right approach after your coronary angiography (heart artery imaging).
La TroncheAges 18 years+ - NCT05841199Recruiting
Study heart blood flow during fast heart rates
This study measures how well blood flows through the heart when the heart rate is increased during a heart procedure. It may help doctors better understand coronary (heart artery) blood flow and how to guide treatment when you need angiography or angioplasty.
LondonAges 18 years+ - NCT06070662Recruiting
New MRI test for small heart vessel disease
This study tests a new way to diagnose small blood vessel disease in the heart using an MRI scan during a stress test. It is for people who are already participating in a larger heart imaging study and are scheduled for a catheter procedure.
Leicester, LeicestershireAges 18 years+ - NCT06075602Recruiting
Complex and calcified coronary artery disease: a registry study
This study watches how people with complex or calcified heart artery disease are treated (with stents or bypass surgery) and how they do over time. It aims to learn which treatments work best for tough blockages.
Lucerne, Canton of LucerneAges 18 years+ - NCT06076551Recruiting
Sex differences in small blood vessel problems of the heart
This study looks at how small blood vessels in the heart work differently in men and women who have chest pain but no major blockages in their main heart arteries. The goal is to better understand and treat these smaller vessel issues.
SeoulAges 20–80 - NCT06125392Recruiting
New Definition for Small Heart Vessel Disease
This trial studies a condition where small heart vessels don't work well. It looks at new ways to define this problem using a special test that measures pressure and blood flow in a heart artery.
Mainz, Rhineland-PalatinateAges 18–90 - NCT06393478Recruiting
Southeastern Europe Microcirculation Registry
This study is collecting information about how well the tiny blood vessels in the heart work in people with chest pain. It helps doctors learn more about microcirculation problems and may lead to better treatments.
RijekaAges 18 years+ - NCT06597851Recruiting
Insulin resistance and heart artery health: a study for chest pain patients
This study looks at how insulin resistance affects tiny heart arteries in people who have chest pain and signs of heart stress on tests, but do not have major blockages in their heart arteries. It aims to understand why some people have heart symptoms even when their main arteries appear clear.
Verona, VRAges 18 years+ - NCT06600178RecruitingPhase 1
Heart medication for women with chest pain and small vessel disease
This trial tests a diabetes medication called SGLT2 inhibitors to see if it can improve blood flow to the heart and reduce chest pain in women who have small vessel heart disease (microvascular dysfunction) but not blocked large arteries. Participants will take the medication and be monitored for symptom relief and heart function improvements.
