Brief Summary
High risk of bleeding (HBR) is a determining factor for the duration of dual antiplatelet therapy (DAPT). Recent studies have shown that the use of one-month DAPT is beneficial in terms of ischemic as well as hemorrhagic events, particularly in HBR patients, compared with longer DAPT. European guidelines therefore authorize one-month DAPT in HBR patients presenting even an acute coronary syndrome. The HT Supreme Drug Coated Coronary Stent System (HT Supreme DES) is designed to promote reendothelialization as quickly as possible. That's why the stent is called "HT" Supreme, with "HT" standing for "Healing Targeted", enabling a DAPT of just 1 month in all-comers HBR patients. Thanks to these features, the investigators aim to demonstrate ischemic and hemorrhagic complication rates lower than those found in the literature with other stent.

Outcome Measures
Primary Outcomes (1)
Rate of occurrence of combined endpoint at 335 days: net averse clinical event (death from any cause, infarction and non-fatal stroke) + (BARC major bleeds >3)).
Validate the non-inferiority of the frequency of occurrence at 335 days after a short DAPT (1 month) of a combined endpoint, net averse clinical event (all-cause death, non-fatal MI and non-fatal stroke) + (BARC major bleeds \>3) occurring in patients implanted with an HT supreme™ coronary stent in HBR patients to the ultimaster stent (Terumo)
At 335 days
Secondary Outcomes (10)
Comparison of primary endpoint (net averse clinical event (all-cause death, non-fatal MI and non-fatal stroke) + (BARC major bleeds >3) ) frequency in patients with HBR and high ischemic risk.
At 335 days and one year
Evaluate the one-year frequency of death from any cause
At 335 days and one year
Evaluate the one-year frequency of cardiovascular deaths
At 335 days and one year

At 335 days and one year
Evaluate the one-year incidence of ischemic stroke
At 335 days and one year
- +5 more secondary outcomes
