The outcome of primary percutaneous coronary intervention in patients with stent thrombosis

Background: Primary percutaneous coronary intervention (PCI) is a recommended management strategy for patients with de novo ST-segment elevation myocardial infarction (STEMI). Still, the efficacy of primary PCI in-stent thrombosis (ST) induced STEMI is unclear. The aim was to assess the clinical characteristics and the in-hospital outcomes of patients undergoing primary PCI for STEMI caused by acute, sub-acute, or late ST. Methods: A sample of hundred consecutive patients who presented with STEMI due to ST were included in this study. The angiographic evidence of a flow-limiting thrombus or total vessel occlusion (thrombolysis in myocardial infarction (TIMI) flow grade 0 to II) at the site of the previous stent implant was taken as ST. Primary PCI was performed, and all enrolled patients and in-hospital mortality were observed. Results: Male patients were 69, and the mean age was 58.9 ± 7.78 years. ST was categorized as acute in 40 patients, sub-acute in 53, and late in the remaining seven patients. Killip class III/IV was observed in 45 patients. Dissection was observed in 25, under deployment in 74, and/or malposition in 24 patients. Thrombus aspiration was performed in 97, plain old balloon angioplasty in 76, and stenting in 22 patients. Final TIMI III flow was achieved in 32 patients. During a mean hospital stay of 4.93 ± 2.46 days, the mortality rate was 27%. Conclusion: In-hospital mortality after primary PCI was observed in more than 1/4th of the patients with STEMI due to ST undergoing primary PCI

Quality of life at six months after primary percutaneous coronary intervention performed at a predominantly rural population

Background: HRQL is important in improving the quality of patient care. However, there is a paucity of data from low-income and middle-income countries (LMIC). Differences in socio-demographics and socio-cultural contexts may influence HRQOL. Therefore, this research was designed with the aim to explore the HRQOL in patients after Percutaneous Coronary Intervention (PCI).Objective: The goal of the study was to evaluate the quality of life after six months of Percutaneous Coronary Intervention using HeartQol questionnaire at a tertiary care hospital in Pakistan.Method: This was a Cross-sectional, descriptive study. Patients between the ages of 20-60 years who underwent primary Percutaneous Coronary Intervention at least 6 months ago were inducted in the study. Coronary angiography was performed mostly through radial as preferred route. Data was collected using a structured questionnaire covering demographic characteristics, predisposing risk factors, procedural details, and quality of life. Heart related Quality of life was assessed using HeartQol questionnaire. Collected data was analyzed using SPSS v.21.Results: A total of 241 patients participated in the study. Mean age of the patients was 53.37±11.07 years. On analysis of quality of life at six months, the median (IQR) HeartQol score was 31 (37-23) with majority of the patients, 84.22% (203) fall under the excellent score (>20).Conclusion: It is of enormous prognostic importance that the quality of life of patient is assessed on a regular basis after PCI. Our study shows that the majority of patients had improved quality of life at six months of PCI. Majority of patients were not bothered by mild symptoms. Further investigation needs to be done to validate these results.
