Intravascular Ultrasound versus Angiography Guided Drug Eluting Stent Implantation in Patients with Left Main Coronary Artery Disease - A Systematic Review and Meta-Analysis.

Background: Several technical limitations exist in angiography procedures, including suboptimal visualization of a particular location and angiography only providing information about the contour of the vascular lumen, while intravascular ultrasound (IVUS) provides information regarding wall composition on coronary vascular lesions. With recent trials demonstrating IVUS benefits over standard angiography, our meta-analysis aimedto evaluate and summarize the current evidence on whether IVUS-guided drug-eluting stent (DES) placement resulted in better outcomes than the angiography-guided DES placement in patients with left main coronary artery (LMCA) disease. This meta-analysis aimed to analyze the current evidence on the IVUS-guided and angiography-guided drug-eluting stent (DES) placement in patients with LMCA disease. Methods: Literature searching was performed using Scopus, Embase, PubMed, EuropePMC, and Clinicaltrials.gov using PRISMA guidelines. The intervention group in our study are patients undergoing IVUS-guided percutaneous coronary intervention (PCI) and the control group are patients undergoing angiography alone-guided PCI. Cardiovascular mortality, all-cause mortality, target lesion revascularization, myocardial infarction, and stent thrombosis were compared between the two groups. Results: There were 11 studies comprising 24,103 patients included in this meta-analysis. IVUS-guided PCI was associated with lower cardiovascular mortality (hazard ratio (HR) 0.39 [95% CI 0.26, 0.58], p < 0.001; I 2 : 75%, p < 0.001) and all-cause mortality (HR 0.59 [95% CI 0.53, 0.66], p < 0.001; I 2 : 0%, p = 0.45) compared to angiography alone guided PCI. The group receiving IVUS guided PCI has a lower incidence of myocardial infarction (HR 0.66 [95% CI 0.48, 0.90], p = 0.008; I 2 : 0%, p = 0.98), target lesion revascularization (HR 0.45 [95% CI 0.38, 0.54], p < 0.001; I 2 : 41%, p = 0.10) and stent thrombosis (HR 0.38 [95% CI 0.26, 0.57], p < 0.001; I 2 : 0%, p = 0.50) compared to the control group. Conclusions: Our meta-analysis demonstrated that IVUS-guided DES placement had lower cardiovascular mortality, all-cause mortality, target lesion revascularization, myocardial infarction, and stent thrombosis than angiography-guided DES implantation.

Risk Factors for Poor Pregnancy Outcome in Systemic Lupus Erythematosus Patients.

BACKGROUND: systemic lupus erythematosus (SLE) is still a challenging autoimmune disease, especially in pregnancy setting. An early risk factors awareness of poor pregnancy outcome is important to optimize the outcome of pregnancy in SLE patients. This study was conducted to describe pregnancy outcome and determine the risk factors associated with poor pregnancy outcome in SLE patients. METHODS: a retrospective case-control study of SLE patients with poor and normal pregnancy outcome was performed. Pregnancy histories were reviewed from Dr. Hasan Sadikin General Hospital lupus registry study. The case group was pregnancy with poor outcome, defined as abortion, premature birth, stillbirth, intrauterine growth restriction (IUGR) and neonatal death. The control group was pregnancy with good outcome, defined as live birth and full term. RESULTS: a total of 84 SLE patients were enrolled in this study with 109 pregnancies after SLE diagnosis. The median age of subjects at the time of pregnancy was 28 (25-32) years old. Poor pregnancy outcome comprising 22.9% abortion, 14.7% premature birth, 5.5% stillbirth, 1.8% IUGR and 4.6% neonatal death. There was a significant difference in the number of planned pregnancy (P=0.011) between groups with poor and good outcome. Clinical variables significantly associated with poor pregnancy outcome were lupus nephritis (OR = 4.813, 95% CI 1.709 - 13.557, P = 0.003) and neuropsychiatric SLE (OR = 5.045, 95% CI 1.278 - 19.920, P = 0.021). CONCLUSION: the pregnancy in SLE patient should be planned to have better outcome. Lupus nephritis and neuropsychiatric (NP) SLE were risk factors for poor pregnancy outcome in SLE patient.

Monocyte to high-density lipoprotein cholesterol ratio as highly predictive marker in patients with acute coronary syndrome.

Aim: This study examined the relationship between Thrombolysis in Myocardial Infarction (TIMI) score and monocyte to high-density lipoprotein cholesterol (HDL-C) ratio (MHR) with Global Registry of Acute Coronary Events (GRACE) in patients with acute coronary syndrome (ACS). Materials & methods: A total of 1000 patients with ACS admitted to the Cardiology Department of the Dustira Army Hospital were included in this study. Medical records were retrospectively reviewed from January 2019 to June 2020 with consecutive sampling. Results: In the group with a higher TIMI score, the MHR result was considerably higher. In the same way, MHR was more significant in the group with a high-risk than in low-risk GRACE. Conclusion: MHR is a convenient, reproducible and correlates with GRACE and TIMI score as predictive biomarkers in patients with ACS.
