About this study
Official title: A Comparison of Fractional Flow Reserve- Versus Angiography-Guided Percutaneous Coronary Intervention in Patients With Left Main Coronary Artery Disease
The primary purpose of the study was to determine whether the 2-year probability of major adverse cardiac events (primary composite outcome) differed significantly between patients who underwent angiography-guided Percutaneous Coronary Intervention(PCI) and those who underwent Fractional Flow Reserve(FFR)-guided PCI in patients with Left Main Coronary Artery disease(LMCA).
Read the detailed description
All participants will be monitored over a span of two years and the time point of the year of last subject last visit. The term "year of last subject last visit" refers to the time point of the last visit for all participants. At this specific time point, event occurrence check will be conducted to determine the occurrence of endpoint events among all participants.

What is being measured
The primary outcome is the main question the study is designed to answer.
The composite event rate
Composite event consists of death from any causes, myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest, or repeat revascularization.
A composite endpoint is an endpoint that is a combination of multiple clinical endpoints. An event is considered to have occurred if any one of several different events is observed.
Measured: 2 years
Secondary outcomes (16)
The event rate of death from any causes
Measured: 2 years
The event rate of myocardial infarction
any, spontaneous or procedural myocardial infarction
Measured: 2 years
The event rate of hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest
Measured: 2 years
The event rate of repeat revascularization
Measured: 2 years
The composite event rate of death or myocardial infarction
Measured: 2 years
The event rate of stent thrombosis
Stent thrombosis by Academic Research Consortium (ARC) definition
Measured: 2 years
The event rate of stroke
Measured: 2 years
The event rate of bleeding complications
Bleeding Academic Research Consortium [BARC] type 3-5, which indicates severe bleeding
Measured: 2 years
Procedure time
Measured: 1 day
Amount of contrast agent used
Measured: 1 day
Length of hospital stay
Measured: an average of 7 day
The event rate of rehospitalization
Rehospitalization from any, cardiac, or noncardiac causes
Measured: 2 years
Functional class
Functional class assessed by the Canadian Cardiovascular Society (CCS) Angina Score classification.
The minimum and maximum values are I and IV respectively and a higher score means a worse outcome.
Measured: 7 days(discharge) and 1, 6, 12, 24 months
Change of angina-related quality of life index
By the Seattle Angina Questionnaire [SAQ].
the SAQ is a disease-specific patient-reported outcome (PRO) with 5 domains. Lower score represents poor health status and high score represents good health status.
Measured: 7 days(discharge) and 1, 6, 12, 24 months
Change of health-related quality of life index
By the EQ-5D.
EQ-5D is a standardised measure of health-related quality of life developed by the EuroQol Group. Range 0 - 1 and a higher score of EQ-5D mean low quality of life.
Measured: 7 days(discharge) and 1, 6, 12, 24 months
Number of anti-anginal medications
Measured: 7 days(discharge) and 1, 6, 12, 24 months
