Aims: We want to study the effect of diabetes Mellitus (DM) on the outcomes in patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) comparing those with non diabetics, with reference to gender.
Methods: We retrospectively evaluated the consecutive patients undergoing PCI either with acute coronary syndrome (ACS) or chronic stable angina (CSA) in our institute between March 2014 to March 2015. We followed them up to one year for the major cardiovascular events (MACES) and other complications. We compared the rate of events between diabetic and non diabetic patients along with gender subgroups and tested for the significance.
Results: In 645 patients undergone PCI in our institute, 326(50.5%) were diabetics, of them 104(31.9%) were females. Patients with diabetes with CAD were older with more incidence of hypertension and kidney derangement than non diabetics. History of CAD and previous procedure are definitely more in diabetics as is multi vessel disease (p=0.02) and LV dysfunction (p=0.003). Total number of patients presenting with complications within one year of PCI is 18(0.02%). Of them 14 are males and 4 are females, 14 were diabetics and 4 were non diabetics. There was no statistical significance in the outcomes between female & males (p=0.7), diabetics females & diabetic males (p=0.48) and non diabetics females & nondiabetic males(p=0.7). Male patients with diabetes had significantly more complications than non diabetic males (p=0.05) but there is no significant difference between diabetic and non diabetic females (p=0.59).
Conclusion: Patients with DM undergoing PCI had more complications than non diabetics with significant difference between male diabetics and non diabetic males. This difference is not significant between diabetic and non diabetic females.
