What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at whether opening a completely blocked heart artery with a procedure called PCI, on top of taking standard heart medications, helps people live longer and feel better compared to medications alone. About 2000 adults with stable heart disease and symptoms like chest pain or shortness of breath are taking part. The main goals are to see if the procedure reduces deaths and improves quality of life.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * ≥1 CTO lesion amenable to PCI. * Stable and stabilized coronary artery disease * Symptoms (angina pectoris or shortness of breath) and/or signs of reversible perfusion defect by SPECT, PET or MR and/or angiographic/echocardiographic indication of reversible ischemia. * CTO lesion in a major coronary vessel supplying a significant myocardial territory (vessel diameter usually ≥3mm). Exclusion Criteria: * Expected survival \<1 year. * Renal failure on dialysis. * Stable non-CTO lesions treated within one month. * Declined informed consent. * Regarding CMR: allergy to contrast medium, severe obesity, claustrophobia and certain metallic implants
