This study tests a newer heart pacing method (left bundle branch pacing) against the standard approach (biventricular pacing) in 60 adults with chronic heart failure and reduced pumping ability. The goal is to see if the newer method improves heart structure, reduces deaths, and …

This study looks at whether giving iron through a vein (Ferinject®) can improve quality of life and walking ability in people with a type of heart failure called HFpEF who also have low iron. About 100 hospitalized adults will receive either iron or standard care. The goal is to …

This study is testing a new approach to reduce heart damage during a heart attack. When a heart artery is blocked, restoring blood flow can sometimes cause additional injury. Researchers are cooling the heart's arteries with a cold saline solution right after opening the blockage…

This study looks at whether measuring how well the left side of the heart pumps in sync can help doctors diagnose microvascular dysfunction—a condition where tiny heart blood vessels don't work properly. Researchers will use a special imaging test (SPECT) to check heart timing in…

This study uses an online survey to identify health risks, medication problems, and self-medication habits in 2000 adults aged 18 and older. Researchers aim to understand how factors like drug interactions and polypharmacy affect active longevity. Participants complete a question…

This study looks at whether problems with mitochondria—the energy factories inside heart cells—are linked to how heart failure progresses. Researchers will take small heart tissue samples and blood from 45 to 60 people with heart failure and blocked arteries who are having bypass…

This study aims to see how often older adults with heart disease were prescribed potentially unsafe medications during the COVID-19 pandemic. Researchers will review medical records of 1,000 patients aged 75 and older who are part of a drug reimbursement program. They will also c…

This study follows 80 adults who had coronary artery bypass surgery to see how developing pneumonia in the hospital affects their heart and lung health over the next year. Researchers will compare medical tests and scans between those who get pneumonia and those who don't. The go…

This study looks at 160 people with heart failure who are scheduled for coronary artery bypass surgery. Researchers want to see if a blood marker called GDF-15 can help predict serious heart events like heart attack or stroke in the year after surgery. Participants will be follow…
