Preoperative Cardiology Consultation and the Incidence of Major Adverse Cardiac Events（MACE）

China22,000 participantsStarted 2015-01-01

Plain-language summary

This cohort study aims to determine when preoperative cardiology consultation is needed to reduce the incidence of major adverse cardiac events (MACE) in elderly patients undergoing non-cardiac surgery. The study collected data on elderly patients with preoperative electrocardiogram (ECG) results who underwent non-cardiac surgery. It was conducted at the First Medical Center of the Chinese People's Liberation Army General Hospital from January 2015 to August 2019. MACE was defined as a composite event occurring within 30 days postoperatively, including acute myocardial infarction, unstable angina, heart failure, new-onset severe arrhythmias, non-fatal cardiac arrest, and cardiac death. Data were extracted using structured query language (SQL) and reviewed by three experienced clinicians. Preoperative cardiology consultation was considered as a mediating variable. By modeling, the confounding factors and risk factors for MACE were identified, and the impact of cardiology consultation as a mediating factor on the incidence of postoperative MACE was evaluated. Additionally, the study aimed to identify which categories of ECG findings necessitate cardiology consultation to reduce the incidence of adverse cardiac events, thereby optimizing the cardiology consultation process.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
