The effectiveness of early angiography and intervention for treating anterior ST-elevation myocardial infarction involving diagonal branches
Keywords:
angiography, diagonal branches, myocardial infarction, revascularizationAbstract
Background: ST-elevation myocardial infarction (STEMI) is life-threatening condition requiring prompt medical attention. The diagonal branches are a group of blood vessels that supply blood to the front of the heart, and their involvement in anterior STEMI can result in worse outcomes. Early diagnosis and intervention are essential for enhancing patient outcomes. Objectives: This study's objective is to assess the efficacy of early angiography and intervention in the treatment of anterior STEMI involving diagonal branches. Methods: We conducted cross-sectional investigation of patients admitted to Medical Training Institute, Lady Reading Hospital, Peshawar, Pakistan during 2022-23, with anterior STEMI involving diagonal branches, including 250 patients whom underwent early angiography and intervention within 12 hours of symptom onset. Medical records were mined for clinical data, including demographics, medical history, electrocardiogram (ECG) findings, hematological laboratory results, and treatment modalities. The primary outcome measure was all-cause mortality at 30 days following hospitalization. Results: Mean age of STEMI patients was 61.91+8.71 years, and 68.8% were males. Median time between onset of symptoms and hospitalization was 3.50+0.78 hours. The 30-day mortality rate was 10.8% overall (27/250). Our results indicated that early intervention improved mortality outcomes, whereas late intervention increased the number of cases requiring revascularization.
