This clinical trial is focused on patients with a condition known as chronically occluded coronary artery, which is a blockage in the heart’s blood vessels that has been present for a long time. The study is investigating the effects of two different durations of a treatment called dual antiplatelet therapy (DAPT). This therapy involves using two medications to prevent blood clots. The medications being studied are Clopidogrel, a film-coated tablet, and Kardegic, an oral solution containing D,L-Lysine Acetylsalicylate, which is a form of aspirin.

The purpose of the study is to compare the effectiveness of a short duration of DAPT, lasting 1 month, with the usual longer duration of 6 to 12 months. The study aims to see how these different durations affect the occurrence of adverse events, such as bleeding or ischemic events, which are problems caused by reduced blood flow, over a period of 12 months. Patients who have successfully undergone a procedure called coronary angioplasty for their blocked artery will be part of this study. This procedure involves using a small balloon to open up the blocked artery.

Participants in the study will be randomly assigned to receive either the short or long duration of DAPT. They will be monitored over the course of a year to track any adverse events, such as bleeding or heart-related issues, and to assess their overall health and quality of life. The study will also evaluate the costs associated with each treatment duration and how well patients adhere to their medication regimen. The goal is to determine which treatment duration is more beneficial for patients in terms of safety and effectiveness.
