Examining the impact of renal dysfunction and diabetes on post-myocardial infarction mortality: insights from a comprehensive retrospective cohort study across different age groups

. Chronic kidney disease (CKD) and diabetes mellitus (DM) contribute significantly to cardiovascular disease (CVD) and mortality, with prevalence increasing. The evolving demographic of myocardial infarction (MI) patients, influenced by sedentary lifestyles and advanced medical care, lacks understanding regarding the interplay of CKD, DM, age, and post-MI mortality. This study aims to address this gap by evaluating the long-term impact of CKD and DM on post-MI mortality across age groups.
