Description of intervention(s) / exposure
Patients with angina and no obstructive coronary artery disease on invasive diagnostic coronary angiography will undergo comprehensive invasive coronary haemodynamic studies at the time of procedure to evaluate possible coronary vasomotor disorder leading to patient's symptoms. Haemodynamic studies will include the assessment of resting angiographic contrast flow, coronary microvascular hyperaemic function, coronary endothelial function and provocative coronary spasm testing. This comprehensive testing will add 30-45 minutes to the diagnostic coronary angiography procedure.
The invasive parameters will be analysed and correlate with non-invasive assessment of contractile reserve obtained from low dose dobutamine stress echocardiography technique, pulse waveform analysis parameters and retinal artery changes.

Statistical methods / analysis
Using a Fisher’s z Test for Pearson Correlation, for alpha=0.05 and power of 80% to detect a clinically significant difference, total sample size of 60 estimated for comparing correlation and association of invasive variables with non-invasive variables.
All collected information for the projects outlined above will be entered into an Excel database. The data will be analysed with the help of a statistician from University of Adelaide using the statistical software SAS 9.4 (SAS Institute Inc., Cary, NC, USA) and Stata Statistical Software: Release 14. College Station, TX: StataCorp LP.
Descriptive statistics of the following variables will be presented: age, gender, body mass index, hypertension, dyslipidemia, diabetes mellitus, smoking history, and moderate-to-severe OSA, in addition to outcome and predictor variables. The descriptive will include frequency tables (frequencies and percentages), means (standard deviations) and medians (interquartile ranges) depending on the distribution of the variable. Graphs and tables will be used to summarize the data.
Intraclass correlation coefficients (ICCs) will be calculated for non-invasive techniques repeated by different assessors.
The association of invasive variables (HMR, CFR and TFC) as outcomes in separate models versus non-invasive predictors (CR, Ax and CRVC) will be investigated using linear regression models.

Summary
Brief summary
About 20-30% of patients with angina have no obstructive coronary artery disease on coronary angiogram (NoCAD). Despite no significant obstructive coronary artery disease, most of these patients continue to experience recurrent chest pain without any definitive diagnosis.
Comprehensive invasive coronary haemodynamic studies at the time of diagnostic coronary angiogram will provide important diagnostic and prognostic implications for the management of coronary vasomotor disorder, but routine assessment is difficult. The hyperaemic microvascular resistance (HMR) is a reliable but invasive measure to assess coronary microvascular function. The planned project will evaluate whether left ventricular contractile reserve (CR), measured with strain imaging on low dose dobutamine stress echocardiography (DSE), is a reliable non-invasive measure of coronary microvascular function.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
Yes
Query!
What data in particular will be shared?
A limited, de-identified set of data available for researchers outside the primary investigators and will be specified in the data sharing plan.
Query!
When will data be available (start and end dates)?
No end date determined. Two years after the publication of the primary results of the study. The endpoint of the availability to be specified by the investigators.
Query!
Available to whom?
Researchers outside the primary investigators.
Query!
Available for what types of analyses?
The type of analyses must be specified in the data sharing agreement between the providing agency and the requesting researchers.
Query!
How or where can data be obtained?
Before data are shared, a data-sharing agreement should be established documenting what data are being shared and how the data can be used. The agreement serves two purposes. First, it protects the agency providing the data, ensuring that the data will not be misused. Second, it prevents miscommunication on the part of the provider of the data and the agency receiving the data by making certain that any questions about data use are discussed. The following items should be covered in the data-sharing agreement:
Period of agreement
The intended use of the data
Constraints on the use of the data
Data confidentiality
Data security
Methods of data-sharing
