An observational study in Coronary Arterial Disease (CAD), Ischemic Heart Disease (IHD) and Percutaneous Coronary Intervention (PCI), sponsored by Aalborg University Hospital. Recruiting at 1 site in Denmark. Open to participants aged 18 Years to 90 Years. Per ClinicalTrials.gov, last updated 2026-07-23.
Sponsored by Aalborg University Hospital · Observational
The primary aim of this study is to evaluate changes in absolute coronary flow and pressure before and after percutaneous coronary intervention in calcified lesions. The secondary aim is to use a machine learning model to predict the outcome of the intervention.
1,123 studies on the registry are indexed under Myocardial Ischemia; 177 are open to participants now.
This study's planned enrollment of 100 is below the median of 318 across 398 observational studies indexed under Myocardial Ischemia.

This a prospective clinical cohort study recruiting patients with stable coronary artery disease referred to invasive coronary angiography on clinical indication with angiographic calcium and eligible for PCI.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

The pressure and flow data will be integrated in a machine learning model
Post-PCI FFR
FFR is measured after PCI is completed.
