Objective: This study aimed to explore the short-term efficacy and safety of primary percutaneous coronary intervention (PCI) in female diabetic patients complicated with acute myocardial infarction (AMI).
Methods: A total of 169 diabetic patients with AMI who underwent primary PCI were selected and divided into group A (52 females) and group B (117 males). The clinical data, characteristics of coronary artery lesions, lengths of hospital stay, and incidences of complications were then compared between two groups.
Results: The average age, history of hyperlipidemia, double branch lesions, triple branch lesions, and left main lesions were significantly higher in group A than in group B (P < 0.05). Smoking history, PCI history, and pre-infarction angina were distinctly lower in group A than in group B (P < 0.05). Thrombolysis in myocardial infarction 3 (TIMI3) flow and TIMI myocardial perfusion grade 3 (TMPG3) after PCI were markedly lower in group A than in group B (P < 0.001). Group A had a higher incidence of complications, such as severe arrhythmia, cardiac function Killip III/IV, cardiogenic shock, major, moderate and mild bleed event, as well as a 30-day mortality rate, compared with group B (P < 0.05).
Conclusion: In summary, our study demonstrated that female diabetic patients with AMI had lower TIMI3 flow and TMPG3 following PCI than male patients, while there was higher incidence of complications and 30-day mortality rate. Therefore, more attention should be paid to the therapy of diabetic women with acute myocardial infarction as well as the control of risk factors.
