This study tested a new tool called the AngioSafe Peripheral CTO Crossing System in 79 people with blocked leg arteries (peripheral artery disease). The goal was to see if the device could safely help doctors place a guidewire through the blockage. The study measured how often th…

This study tested the INDIGO Aspiration System, a device that uses a vacuum to remove blood clots from arteries and veins. It included 500 patients in Japan with acute limb ischemia, mesenteric artery occlusion, or severe deep vein thrombosis. The goal was to confirm the device's…

This study compared angioplasty for one blocked leg artery versus multiple blocked arteries in 40 people with critical limb ischemia, a severe condition that can lead to amputation. The goal was to see which approach better saves limbs and heals wounds. Researchers tracked whethe…

This study tested a device called the JETi system to remove blood clots from veins or arteries in the arms or legs. It included 12 adults of Asian descent in Hong Kong. The goal was to see how well the device cleared clots and if it caused serious side effects like bleeding or re…

This study tested a virtual cardiac rehabilitation program using a smartphone app, a fitness wristband, and a blood pressure monitor for people who recently had a heart attack, heart surgery, or a stent. The goal was to see if this home-based program could improve walking ability…

This study looked at whether raising the head after a stroke procedure helps patients recover better. Over 1,300 adults with severe strokes were followed for 90 days to see if head elevation improved their ability to function. The goal was to find a simple, low-cost way to boost …

This phase 3 trial tested a drug called tenecteplase in 452 people with a severe type of stroke caused by a blockage in the basilar artery at the back of the brain. Participants received either tenecteplase or the current best treatment (which could include another clot-buster or…

This study looked at 345 people with a severe stroke caused by a blockage in the basilar artery, a major blood vessel in the brain. It compared two treatments: giving a clot-busting drug followed by a procedure to remove the clot, versus doing the procedure alone. The goal was to…

This study tested a simple method to prevent wrist artery blockage after a common heart procedure. Over 1500 patients had their wrist artery pressed with a special thick gauze pad plus a standard device, or just the device alone. The goal was to see if the gauze method reduced ar…

This Phase 3 trial tested whether the clot-busting drug tenecteplase could improve vision in people with a central retinal artery occlusion (eye stroke). 81 participants received either tenecteplase or aspirin within 4.5 hours of symptoms. The main goal was to see if more patient…

This study tested a computer program called Heuron CTA that looks at brain CT scans to find large blockages in blood vessels. Researchers compared the software's results to diagnoses made by medical experts using scans from 270 adults. If accurate, this tool could help doctors di…

This study tested whether special MRI scans can better detect signs of central retinal artery occlusion (CRAO), also known as an eye stroke. Researchers enrolled 63 adults with CRAO and performed detailed brain and eye imaging. The goal was to find imaging clues that help diagnos…

This study looked at whether a panel of blood biomarkers can quickly identify stroke patients who have a large vessel occlusion (a major blockage) and would benefit from a specialized clot-removal procedure. Researchers enrolled nearly 3,900 adults with stroke symptoms and tested…

This study looked at 1168 adults who had a heart catheterization through the wrist. It compared two methods to stop bleeding and prevent a common complication called radial artery occlusion: manual compression (hand pressure) and a pneumatic device that gradually releases pressur…

This trial investigates whether genetic variations in the CES1 gene influence how the body responds to the blood thinners clopidogrel and aspirin. Healthy Amish adults will take clopidogrel for a week, then a single dose of aspirin, with blood tests measuring platelet function be…
