CORONARY ARTERY BYPASS GRAFT (CABG)

This study compared a new, non-invasive oxygen measurement (Oxygen Reserve Index, or ORI) with standard breathing tests (spirometry) to see which better predicts lung complications after coronary artery bypass surgery. Researchers enrolled 142 adults undergoing elective bypass su…

This study tested whether early exercise guided by wearable AI heart monitors can improve recovery after coronary artery bypass surgery. 84 patients were split into three groups: usual care, usual care plus aerobic exercise, or usual care plus resistance exercise. Both exercise g…

This study tested a special 'ultra-fast-track' anesthesia for people having heart bypass surgery. The goal was to wake patients up and remove their breathing tube right in the operating room or within an hour, instead of the usual ICU stay. Researchers compared 100 patients to se…

This study analyzed health records from over 400,000 adults who had heart surgery to see if the sedative dexmedetomidine helped prevent problems like confusion, kidney injury, or death within 30 days. Researchers compared patients who received the drug around surgery time to thos…

This study compared two different solutions used to protect the heart during coronary artery bypass surgery. Forty adults having non-urgent bypass surgery at a Swedish hospital took part. Researchers measured heart damage markers in blood samples and checked recovery outcomes lik…

This study looked at whether a condition called cardiovascular autonomic neuropathy (nerve damage affecting heart control) increases the risk of kidney injury after coronary bypass surgery. Researchers followed 912 adults undergoing planned bypass surgery and tracked kidney funct…

This study looked at 70 adults having open heart surgery to compare two types of heart-lung machines: a newer, less invasive one versus the standard machine. The goal was to see which method better protects the body's tissues and the brain during surgery. Researchers measured oxy…
