PROGNOSTIC SIGNIFICANCE OF ALBUMINURIA IN DIABETIC AND NON-DIABETIC PATIENTS WITH RECENT ACUTE MYOCARDIAL INFARCTION

Abstract Background Following acute myocardial infarction (AMI), most patients receive potent antithrombotic medications, which may promote nuisance bleedings (ecchymoses, minor nose or dental bleeds etc.). Little information is available on the factors related to nuisance bleedings, nor on their prognostic significance in post-AMI patients. Aims and methods A health status questionnaire was sent to all patients participating in the nationwide French FAST-MI cohorts (2010 and 2015) one year after the acute episode, with a specific question on the presence of nuisance bleedings. Overall, 3968 patients answered the question on the presence nuisance bleedings. In the 2010 cohorts, we also analysed whether the presence of nuisance bleedings at one year was an independent correlate of 5-year mortality. Results 54% of the patients reported the presence of nuisance bleedings (59% in 2010 and 51% in 2015). In univariate analyses, nuisance bleedings were more frequently found in younger patients, women, patients with STEMI, current smokers, patients treated with PCI, those receiving newer P2Y12 inhibitors or ACE-inhibitors but less frequent in patients with diabetes, hypertension, or those receiving ARBs or direct oral anticoagulants. Using logistic regression analysis, however, the only independent correlates of nuisance bleedings were: female gender (OR 1.45, 1.25–1.68), age ≤60 years (OR 1.22, 1.06–1.41), VKAs (OR 1.72, 1.28–2.31), clopidogrel (OR 1.62, 1.29–2.03), prasugrel (OR 3.16, 2.43–4.09), ticagrelor (OR 2.61, 2.04–3.35) at discharge, diabetes (OR 0.74, 0.63–0.88) and year 2015 vs 2010 (OR 0.62, 0.53–0.73). In the 2010 cohort, the presence of nuisance bleeding at one year was not a predictor of mortality at 5 years (90% survival in both patients with or without nuisance bleedings; adjusted HR 0.96, 95% CI 0.69–1.33) (Figure). Figure 1. 5-yr survival by nuisance bleed Conclusion Nuisance bleedings one year after AMI are extremely frequent. They are more common in women, younger patients, in patients receiving P2Y12 inhibitors, especially newer P2Y12-i, and in those receiving VKAs; in contrast, diabetic patients report less nuisance bleedings. The presence of nuisance bleeding at one year does not appear to impact 5-year mortality.

Hba1c Levels

Frequent fluctuations of hemoglobin A1c (HbA1C) values predict patient outcomes. However, data regarding prognoses depending on the long-term changes in HbA1C among patients after acute myocardial infarction (AMI) are scarce. We evaluated the prognostic significance of HbA1C levels and changes among diabetic patients (n = 4066) after non-fatal AMI. All the results of HbA1C tests up to the 10-year follow-up were obtained. The changes (∆) of HbA1C were calculated in each patient. The time intervals of ∆HbA1C values were classified as rapid (<one year) and slow (≥one year) changes. The outcome was all-cause mortality. The highest mortality rates of 53.8% and 35.5% were found in the HbA1C < 5.5–7% and ∆HbA1C = −2.5–(−2%) categories. A U-shaped association was observed between HbA1C and mortality: adjOR = 1.887 and adjOR = 1.302 for HbA1C < 5.5% and ≥8.0%, respectively, as compared with 5.5–6.5% (p < 0.001). Additionally, ∆HbA1C was associated with the outcome (U-shaped): adjOR = 2.376 and adjOR = 1.340 for the groups of <−2.5% and ≥2.5% ∆HbA1C, respectively, as compared to minimal ∆HbA1C (±0.5%) (p < 0.001). A rapid increase in HbA1C (but not decrease) was associated with a greater risk of mortality. HbA1C values and their changes are significant prognostic markers for long-term mortality among AMI-DM patients. ∆HbA1C and its timing, in addition to absolute HbA1C values, should be monitored.
