RESUMO
PURPOSE: The role of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in managing cardiovascular outcomes in patients with type 2 diabetes mellitus (T2DM) is evolving. This meta-analysis seeks to explore the influence of SGLT2i on the recurrence of atrial fibrillation (AF) following catheter ablation (CA) in individuals with T2DM qualitatively and quantitatively. METHODS: A comprehensive literature search was conducted in electronic databases. Studies meeting predefined criteria were included. Individual patient data (IPD) were used from reconstructed time-to-event data to estimate hazard ratios (HRs) and 95% confidence intervals for AF recurrence. IPD meta-analysis was followed by a direct meta-analysis to assess the risk of AF recurrence. RESULTS: A total of five studies [one randomized controlled trial (RCT) and four cohort studies] were included in this study, and five studies were included in the qualitative analysis, while four studies comprising 1043 patients with T2DM were included in the quantitative analysis. The pooled Kaplan-Meier curve based on reconstructed data showed a significantly lower risk of AF recurrence in the SGLT2i group compared with all antidiabetic drugs (log-rank P = 0.00011) and dipeptidyl-peptidase IV inhibitors (DPP4i) (log-rank P = 0.01). Cox regression analysis showed consistent results. Direct meta-analysis showed that SGLT2i, compared with all antidiabetic medications (HR 0.57, 95% CI [0.44, 0.73], I2) and DPP4i (HR 0.41, 95% CI [0.24, 0.70], I2), was associated with a lower risk of AF recurrence. CONCLUSIONS: SGLT2i are associated with a reduced risk of AF recurrence after CA in patients with T2DM. These results suggest that SGLT2i is promising in improving clinical outcomes for this population.
RESUMO
Background and Objectives: Inflammation is considered a risk factor for venous thromboembolism. The association between inflammatory markers and the severity of acute pulmonary embolism (APE) has not been explored. Methods: We studied the association between two crude markers of inflammation, serum albumin, and red cell distribution width (RDW) and massive versus non-massive APE. Results: Among 552 consecutive cases of CT-angiogram-confirmed APE, a total of 46 cases (8.3%) had massive APE. Despite similar demographics and comorbidities, patients with massive APE had higher frequency of acute kidney injury (P = 0.005), higher lactic acid (P = 0.011), higher troponin (P = 0.001), higher BNP (P < 0.001), higher frequency of RV dilation (P = 0.017) and hypokinesis (P = 0.003), and higher in-hospital mortality (15.2% vs. 2%, P < 0.001). Patients with massive APE had significantly lower albumin level (median (IQR): 2.8 (2.2, 3.0) vs. 3.2 (2.8, 3.6) gm/dL, P < 0.001) and higher RDW (median (IQR): 14.7 (13.8, 17.1) vs. 14.2 (13.3, 15.6), P = 0.006) compared with non-massive APE. ROC curves showed that albumin and RDW had an AUC of 0.750 (P < 0.001) and 0.621 (P = 0.006) in predicting a massive APE, respectively. The optimal cutoff values for albumin and RDW that had the highest combined sensitivity and specificity for predicting APE was ≤3 gm/dL and >14, for albumin and RDW, respectively. Restricted cubic splines showed a significant association between albumin (P = 0.0002) and RDW (P = 0.0446) and the occurrence of massive APE. After adjustment for patients' age, body mass index, white blood cell count, the requirement of antibiotics during hospitalization, diabetes, RDW, and peak creatinine, serum albumin was independently associated with massive APE (OR 0.234, 95% CI 0.129-0.4242, P < 0.001). Conclusion: low serum albumin is associated with massive APE. This association is likely a proxy for higher inflammatory state in massive compared with non-massive APE.
