Using a heart rate and blood pressure index to predict heart problems after abdominal surgery
Part of Heart & circulation clinical trials.
This study looks at whether a simple heart rate and blood pressure measure (called the modified shock index) can help predict heart problems after major abdominal surgery. The researchers want to study people who already have heart conditions or risk factors, to see if this index can warn their doctors early.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 45 years old or older.
- You are having or had major abdominal surgery that lasted at least 2 hours.
- You have a history of heart disease, or had a blood test for heart strain (BNP or troponin) within 30 days before surgery that was high, or you have at least two heart risk factors (like high blood pressure, diabetes, smoking, or high cholesterol).
- You do not have a severe acute heart problem, severe uncontrolled high blood pressure, kidney failure needing dialysis, sepsis, or need strong medicines to keep your blood pressure up before surgery.
- You are not pregnant, and you agree to let the researchers use your medical records.

Other trials that look related to this one.
This trial checks a blood test called NT-proBNP (a marker related to heart stress) to help predict outcomes after planned surgery. It may help doctors identify which patients are at higher risk so they can tailor monitoring and care.
This study follows people after major surgery to see what predicts heart and blood vessel problems later. It does not test a new drug; it mainly collects health information to help clinicians reduce risk.
This trial tests a tool that predicts drops in blood pressure during major abdominal surgery. It may help doctors manage blood pressure better during and after surgery.
This study checks whether close monitoring of vital signs around the time of non-cardiac surgery can help identify small heart injuries (called perioperative myocardial infarction or injury). It may help doctors spot people at higher risk sooner, especially after certain major surgeries.
This study looks at how well the heart pumps blood to predict recovery after abdominal surgery in people 65 and older. It uses an ultrasound of the heart (echocardiogram) to measure heart power and a standard score to estimate surgical risk.
This study looks at whether a simple blood pressure measurement during surgery can predict which older patients may develop high blood pressure after surgery. If you are 65 or older and having planned surgery with a blood pressure monitor placed in an artery, you may be able to join.
