“…The GRACE risk score is a reliable method of stratifying the severity of acute coronary syndrome [ 33 ] and is recommended by the current guidelines [ 34 ]. However, it seems to be limited in practice, as it does not wholly capture the indices (oxidative stress and inflammation, for example).…”
This is an observational, retrospective, single-center study aimed to determine whether the free triiodothyronine (FT3) to free thyroxine (FT4) ratio was related to acute myocardial infarction (AMI) prognosis in individuals with type 2 diabetes mellitus (T2DM). A total of 294 euthyroid T2DM patients with new-onset AMI were enrolled. FT3/FT4 ratio tertiles were used to categorize patients into Group 1 (FT3/FT4 ≥ 4.3), Group 2 (3.5 ≤ FT3/FT4 < 4.3), and Group 3 (FT3/FT4 < 3.5). Major adverse cardiac events (MACE), including nonfatal myocardial infarction, target vessel revascularization (TVR), and cardiac mortality, served as the primary endpoint. Group 3 demonstrated a considerably higher incidence of MACE than the other two groups over the average follow-up duration of 21 ± 6.5 months (all p < 0.001). Multivariable Cox regression analysis showed that a low FT3/FT4 ratio was an independent risk factor for MACE after AMI (Group 1 as a reference; Group 2: hazard ratio [HR] 1.275, 95% confidence interval [CI]: 0.563–2.889, p = 0.561; Group 3: HR 2.456, 95% CI: 1.105–5.459, p = 0.027). Moreover, the area under the receiver-operating characteristic curve (AUC) indicates a good predictive value of FT3/FT4 ratio for MACE (AUC = 0.70). Therefore, in T2DM patients with AMI, a low FT3/FT4 ratio was strongly linked to poor prognosis.

“…We conducted a retrospective, bicenter registry study at 2 tertiary referral hospitals, Chiba University Hospital and Eastern Chiba Medical Center [ 13 , 14 , 15 , 16 , 17 , 18 ]. From January 2012 to March 2020, a total of 1102 patients with acute MI including ST-segment elevation MI (STEMI) and non-ST-segment elevation MI (NSTEMI) underwent primary PCI.…”
Among patients with acute myocardial infarction (MI) complicated by cardiogenic shock (CS), in-hospital mortality remains high. In the present study, we aimed to identify factors associated with clinical outcomes of acute MI patients with CS in a contemporary setting. A total of 1102 patients with acute MI undergoing primary percutaneous coronary intervention were included, among whom 196 (17.8%) were complicated by CS. The primary outcome was all-cause death during hospitalization, and factors associated with in-hospital mortality were explored in patients with acute MI and CS. Of the 196 patients with acute MI complicated by CS, 77 (39.3%) died during hospitalization. The rates of non-ST-segment elevation MI (NSTEMI) (33.8% vs. 19.3%, p = 0.02) and culprit lesion in the left main or left anterior descending coronary artery (68.8% vs. 47.9%, p = 0.004) were higher, while left ventricular ejection fraction (LVEF) was lower (24.4 ± 11.7% vs. 39.7 ± 13.8%, p < 0.001) in non-survivors than in survivors. Multivariable analysis identified NSTEMI presentation and lower LVEF as independent predictors of in-hospital death. In conclusion, NSTEMI and low LVEF were identified as factors associated with higher in-hospital mortality. The identification of even higher-risk subsets and targeted therapeutic strategies may be warranted to improve survival of patients with acute MI and CS.
“…From January 2012 to March 2020, 1102 patients with acute MI, including STsegment elevation and non-ST-segment elevation MI, underwent primary PCI. Details of the registry have been previously described (7)(8)(9)(10). In brief, acute MI was defined according to the fourth universal definition of MI (11).…”
Objective Oral diseases, including periodontitis and stomatitis, are highly prevalent worldwide and reportedly associated with the development of cardiovascular disease. Given the high rate of stomatitis in individuals wearing dentures, denture users may be at high risk of poor cardiovascular outcomes. We therefore investigated whether or not the use of dentures is associated with a poor clinical outcome in patients with acute myocardial infarction (MI). Methods This two-center retrospective observational study was conducted between January 2012 and March 2020. A total of 1046 patients with acute MI who underwent primary percutaneous coronary intervention were divided into two groups according to denture use status. The primary outcomes included ischemic events (cardiovascular death, recurrent MI, and ischemic stroke) and major bleeding (Bleeding Academic Research Consortium type 3 or 5). Results Of the 1046 patients with acute MI, 387 (37.0%) used dentures. An older age and prior MI were associated with an increased likelihood of denture use. During the mean 660-day follow-up period, ischemic and major bleeding events occurred in 169 (16.2%) and 102 (9.8%) patients, respectively. Denture use was associated with an increased risk of ischemic events, whereas no significant intergroup differences were observed in major bleeding outcomes. The results were similar among patients ! 75 years old. Conclusions More than one-third of the patients with acute MI wore dentures. Our findings suggest that denture use is significantly associated with an increased risk of ischemic events but not bleeding outcomes after acute MI.
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.
