Lucerne, Canton of LucerneAges 18 years+ - NCT05346068Recruiting
Compare two balloon types for calcium-heavy blocked heart arteries
This trial studies whether one type of balloon works better than another for treating badly calcified (hardened) coronary artery blockages. If you qualify, you would be randomly assigned to get the tested balloon treatment during your heart procedure.
LucerneAges 18 years+ - NCT05800002Recruiting
IVUS-guided stent placement for badly calcified heart arteries
This trial studies a heart procedure that uses a special camera to guide where to place a drug-coated stent in an artery with heavy calcium. It may help improve how well the stent fits and works for people with certain types of coronary artery blockages.
Nanjing, JiangsuAges 18 years+ - NCT05845424RecruitingPhase 4
High-intensity cholesterol pills for people with silent calcium
This trial studies whether high-intensity statin plus ezetimibe can improve heart health in people who do not have symptoms but have calcium buildup in their heart arteries. It may help lower cholesterol and reduce future heart risks for the right participants.
SeoulAges 40 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+ - NCT06235112Recruiting
AI Screening for Heart Calcium from Chest CT Scans
This research study uses an artificial intelligence program to screen old chest CT scans for calcium buildup in the heart arteries. If you are between 40 and 75 and have had a chest CT in the last 3 years, this may help identify if you are at risk for heart disease so you can take steps to prevent it.
Boston, MassachusettsAges 40–75 - NCT06711822Recruiting
Shockwave catheter for calcified heart artery blockages
This study tests a new catheter device (ShockPulse-10) that uses shockwaves to crack calcium in heart arteries before placing a stent. It is designed for people with hard, calcified blockages that are difficult to treat with balloons alone.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06736665Recruiting
Comparing two ways to treat hardened calcium in heart arteries
This trial compares two techniques (orbital atherectomy and intravascular lithotripsy) to break up tough calcium deposits in the heart's arteries that can block blood flow. If you have a calcified nodule and are having a non-emergency procedure to open a blocked artery, this study may help guide which method works best.
Alicante, AlicanteAges 18 years+ - NCT06767345RecruitingPhase 4
Comparing two cholesterol medicines for plaque stabilization
This study compares two ways to lower cholesterol and stabilize artery plaque in people with coronary artery disease who are having a stent procedure. It tests whether a moderate statin plus ezetimibe works as well as a high-intensity statin alone for stabilizing plaque.
Seoul, SeoulAges 18 years+ - NCT07000045Recruiting
Shock wave vs drill for hard calcium in heart arteries
This study tests a new way to break up hard calcium deposits in heart arteries using shock waves (lithotripsy), with or without a special drill (rotational atherectomy), before placing a stent. It may help people with severely calcified blockages that are hard to treat with standard methods.
New York, New YorkAges 18 years+ - NCT06507449Enrolling by invitation
Treating Heavily Calcified Heart Blockages to Improve Microcirculation
This study is testing a technique to treat heavily calcified (hard) blockages in heart arteries. The goal is to see if a special way of preparing the blockage before placing a stent helps improve blood flow to the tiny blood vessels in the heart muscle.
KatowiceAges 18 years+ - NCT04795193Enrolling by invitation
Minithoracotomy vs open surgery for multiple blocked heart arteries
This trial compares two types of bypass surgery for people with multiple blocked heart arteries, to see which one better improves quality of life and how well the bypasses stay open. You may be assigned based on your preferences, and the study also tracks heart scan and follow-up results.
