Objectives: To elucidate the involved culprit arteries and proportion of spontaneous arterial recanalization (SAR) in acute lateral wall myocardial infarction (ALWMI) patients in Pakistan.
Methodology: This cross-sectional study was conducted in the outpatient department (OPD) of a tertiary care cardiac center from February 2019 to July 2019. Patients meeting selection criteria of ALWMI were included. Key angiographic outcomes were recorded for each patient. Proportion of SAR in terms of involved culprit arteries was assessed.
Results: One hundred fifty two (152) patients were included, out of which 81% (124) were males. Mean age was 54.73 ± 11.03 years. Most (46.4%) of the study patients presented with single vessel disease. Overall, 89 (59%) patients showed SAR with settled ECG changes. Of them 73 (66%), 8 (33%) and 8 (47%) patients had diagonal artery involvement, 1st obtuse marginal artery involvement and ramus intermedius artery involvement respectively. Statistical significance (p=0.006) is observed for relationship of involved culprit arteries and SAR in ALWMI patients.
Conclusion: This cross-sectional study reports the proportion of arterial recanalization in terms of involved culprit arteries. Diagonal was the culprit artery (~ 73%) in most patients presented with ALWMI. SAR proportion is also highest in patients with diagonal artery involvement. This tendency of SAR was more in single vessel diseases patients compared to double vessel and triple vessel diseases patients.
Background In underdeveloped countries, coronary artery disease (CAD) has developed into a serious health issue due to the high rates of risk factors such as obesity and smoking amongst the population. This study has been performed to find the rate of multivessel CAD (MVD) and subsequent thrombolysis in myocardial infarction (TIMI) flow grade III in patients undergoing primary percutaneous coronary intervention (PCI). Methods This transverse study was carried out involving 110 patients from the emergency department of the National Institute of Cardiovascular Diseases, Karachi, Pakistan, from August 2015 to March 2016. All patients were diagnosed as ST-segment elevation myocardial infarction (STEMI) and had gone through primary PCI. Pre-procedure angiographic findings regarding the number of vessels involved and post-procedure TIMI flow grade were assessed and analysed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
