Study summary

The International Registry of Acute Coronary Syndromes registry study (ISACS) is both a retrospective and prospective study which was designed in order to obtain data of patients with acute coronary syndromes, and herewith control and optimize internationally guideline-recommended therapies in these countries

Read the detailed description

Aims of this survey study are (1) documentation of the characteristics of all patients presenting to the ISACS centers with STEMI or NSTEMI (2) documentation of in-hospital outcome, and outcome rates at 6 month and 1 year, (3) documentation of invasive procedures and procedure-associated complications (4) documentation of therapeutic regimens and investigation conformity of treatment with already established guidelines.

Inclusion criteria

  • acute coronary syndromes

Exclusion criteria

Exclusion Criteria:

  • under age or not able to give
Terms in these criteria, in plain language(1)

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.

Informed consent

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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Sep 2010 (actual). Primary completion is estimated for Dec 2026, 195 months after the start.

Of 243 non-industry observational studies under Acute Coronary Syndrome, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 71. This study's planned 195 months is above that.

Counting every sponsor, half of 277 studies reached it within 35 months; a quarter within 18 and three quarters within 68.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 16, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
