1 Introduction Catheter-induced left main coronary artery (LMCA) dissection is an uncommon but potentially catastrophic complication of diagnostic coronary angiography and percutaneous coronary intervention, with an estimated incidence between 0.02% and 0.09% [1]. It results from deep catheter engagement, forceful contrast injection, or direct catheter tip trauma during selective engagement.

Abstract Background Acute coronary syndrome (ACS) patients with multiple cardiovascular risk factors face particularly high recurrence rates. The differential impact of cardiac rehabilitation across ACS subtypes in high-risk patients remains understudied. Methods This prospective, randomised, single-center study evaluated cardiac rehabilitation effects on adherence across ACS subtypes in high-risk patients.

1 Introduction Acute coronary syndrome (ACS), encompassing conditions such as ST-elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), and unstable angina, is a significant contributor to cardiovascular morbidity and mortality worldwide [1]. Despite advancements in pharmacological treatments, revascularization techniques, and preventive strategies, patients recovering from ACS remain at high risk for recurrent cardiovascular events, hospitalizations, and adverse outcomes [2].
