RESUMO
Background: This retrospective cohort study aimed to compare the outcomes of graft angiography using these two approaches. Methods: Medical records and angiographic data of adult patients who underwent graft angiography between January 2020 and December 2022 were analyzed. Results: The study included 452 patients in the distal radial access (DRA) group and 960 patients in the femoral access group. Angiographic characteristics showed a higher prevalence of triple vessel disease in the femoral access group (29.8% vs. 20.8%; p = 0.012). The DRA group had a procedural success rate of 93.0%, while the femoral access group had a higher success rate of 95.8%. The odds ratio was 0.66 (95% CI: 0.46-0.94), indicating lower odds of procedural success in the DRA group. Conclusion: Our study suggests that both DRA and femoral access are effective and safe approaches for graft angiography after coronary artery bypass surgery.
This study compared graft angiography outcomes using wrist (distal radial) and groin (femoral) access in patients after coronary artery bypass surgery. Analyzing data from January 2020 to December 2022, 452 patients used wrist access, and 960 used groin access, with similar age and heart function across groups. Femoral access had more cases of triple vessel disease (29.8% vs. 20.8%) and a higher success rate (95.8% vs. 93.0%), with wrist access showing lower odds of procedural success. Despite this, both methods proved to be effective and safe.
RESUMO
Antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis (GN) is an immune-mediated kidney disease characterized by the inflammation of small blood vessels in the kidney, leading to renal impairment and potentially irreversible damage. Concerns have been raised over the reports of myeloperoxidase/perinuclear (MPO/p) ANCA GN following the coronavirus disease 2019 (COVID-19) vaccination. Our study provides a comprehensive insight into perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA) GN after COVID-19 vaccination. We conducted a comprehensive literature search on PubMed, Cochrane Library, and EMBASE using the Medical Subject Headings (MeSH) terms related to "covid-19 vaccine," "glomerulonephritis," "p-ANCA," and "MPO-ANCA" up to March 5, 2024, to include cases of p-ANCA-associated GN following COVID-19 vaccination. Of the 4,102 articles, we included 29, reporting 35 patients demonstrating COVID-19 vaccine-induced p-ANCA GN, with 23 (65.7%) females and a median age of 69 years (mean ± SD = 63.22 ± 16). Twenty-six (74.28%) patients received the mRNA vaccine (Pfizer = 19, Moderna = 7). Seventeen (48.57%) patients presented with p-ANCA GN after the second dose of the COVID-19 vaccine, with a median gap of 19 days (1-84 days). Constitutional symptoms (54.28%) and acute kidney injury (42.85%) were the most reported initial presentations, and elevated serum creatinine (mean peak serum creatinine = 4.98 ± 5.02 mg/dL), hematuria, and proteinuria were the laboratory findings. MPO/p-ANCA was positive in 31 (88.6%) patients. All patients underwent renal biopsy, and crescentic GN was the most common finding among 27 (77.14%) patients. Management of p-ANCA GN included steroids in 30 (85.71%) patients, followed by rituximab (28.57%), and plasmapheresis (22.86%). Most patients responded well to treatment, with complete remission in 29 (82.86%) and relapse in four (11.42%) patients. Two patients did not achieve remission and became dialysis dependent. ANCA-associated GN is a rare and life-threatening complication of the COVID-19 vaccine, necessitating urgent evaluation and management. COVID-19 vaccine-induced p-ANCA GN should be included in the differential diagnoses of patients presenting with kidney injury after vaccination.
RESUMO
Takotsubo cardiomyopathy (TCM) is a life-threatening transient left ventricular dysfunction triggered by either physical or emotional stressors. Concerns have been raised on reports of TCM after the coronavirus disease 2019 (COVID-19) vaccine. Our study provides comprehensive detail on COVID-19 vaccine-induced TCM. We conducted a systemic literature search using major databases, including PubMed, EMBASE, and Google Scholar up to November 2023, to identify cases of COVID-19 vaccine-induced TCM using the MeSH terms and keywords "covid-19 vaccines" and "takotsubo cardiomyopathy". We identified 15 case reports, including 16 patients with COVID-19 vaccine-induced TCM. The mean age was 55.81 ± 19.13 years, and 75% of the patients were female. The most common presentation was chest pain (62.5%), and the average time to first symptom onset was 3.12 ± 2.24 days. COVID-19 vaccine-induced TCM was reported in 43.75% of patients receiving the first and second dose each, and 87% of patients had messenger ribonucleic acid (mRNA) COVID-19 vaccine (Pfizer, Moderna). The elevated level of cardiac troponins was found in all the patients with a left ventricular ejection fraction (LVEF) of <50% in 15 patients, and T-wave inversion (50%) was the most common electrocardiographic finding. The mean length of the hospital stay was 7.27 ± 3.95 days, and 87% of patients were discharged. COVID-19 vaccine-induced TCM is a rare but life-threatening complication. TCM should be included in the differential diagnosis of chest pain or dyspnea in patients recently receiving the COVID-19 vaccine.
