Temporal trends of one-year reinfarction and mortality rates following primary angioplasty in high-risk acute myocardial infarction patients

Background: Elderly survivors of acute myocardial infarction (AMI) are at elevated risk for hemorrhagic stroke, which has a mortality rate of approximately 50%. Increasing use of warfarin for arterial fibrillation and anti-platelet agents for AMI combined with an increasing aging population may have influenced the risk of post-AMI strokes. We sought to characterize temporal trends in the risk for and mortality from hemorrhagic stroke over 12 years among older AMI survivors of different age, sex, race, revascularization status, and region within the US. Methods: We used 100% of Medicare inpatient claims data to identify all fee-for-service (FFS) patients aged> 64 years who were hospitalized for AMI in 1999-2010. We excluded patients who died during the hospitalization or were transferred. Revascularization procedures were identified during the index admission. We used a Cox proportional-hazards regression model to estimate the risk-adjusted annual changes in one-year hemorrhagic stroke hospitalization after AMI, overall and by subgroups. Changes were adjusted by age, gender, race, medical history and comorbidities. We calculated the 30-day mortality among patients readmitted for hemorrhagic stroke. Stroke belt regions were defined as the states with high stroke hospitalization rates in the southeast United States. Results: Among 2,433,036 AMI hospitalizations and 4,852 hemorrhagic stroke readmissions, the risk-adjusted one-year post-AMI hemorrhagic stroke rate remained stable from 1999 to 2010 (range, 0.2% to 0.3%). No significant trends were found for post-AMI stroke rates across all age-sex-race groups and all treatment groups (Figure). Thirty-day mortality rates for stroke after AMI did not show significant changes (1999, 46.7%, 95% CI 39.9%-53.7%; 2010, 50.7%, 95% CI 45.3%-56.1%; range: 46.5% to 54.6%). No difference was found in post-AMI hemorrhagic stroke rates between the stroke belt and non-stroke belt regions. Conclusions: From 1999 to 2010, the overall hospitalization rates of hemorrhagic stroke after AMI were relatively stable without significant changes across all subgroups. Thirty-day mortality rates remained largely unchanged over time. Stroke risk in the stroke belt was not found significantly higher comparing with non-stroke belt states.

Aim. This study was designed to evaluate the relationship between microRNAs (miRNAs), miR-126-3p and miR-223-3p, as new biomarkers of platelet activation, and predicting recurrent thrombotic events after acute myocardial infarction (AMI). Methods and Results. The analysis included 598 patients randomized in the PRAGUE-18 study (ticagrelor vs. prasugrel in AMI). The measurements of miRNAs were performed by using a novel miRNA immunoassay method. The association of miRNAs with the occurrence of the ischemic endpoint (EP) (cardiovascular death, nonfatal MI, or stroke) and bleeding were analyzed. The miR-223-3p level was significantly related to an increased risk of occurrence of the ischemic EP within 30 days (odds ratio (OR) = 15.74, 95% confidence interval (CI): 2.07–119.93, p = 0.008) and one year (OR = 3.18, 95% CI: 1.40–7.19, p = 0.006), respectively. The miR-126-3p to miR-223-3p ratio was related to a decreased risk of occurrence of EP within 30 days (OR = 0.14, 95% CI: 0.03–0.61, p = 0.009) and one year (OR = 0.37, 95% CI: 0.17–0.82, p = 0.014), respectively. MiRNAs were identified as independent predictors of EP even after adjustment for confounding clinical predictors. Adding miR-223-3p and miR-126-3p to miR-223-3p ratios as predictors into the model calculating the ischemic risk significantly increased the predictive accuracy for combined ischemic EP within one year more than using only clinical ischemic risk parameters. No associations between miRNAs and bleeding complications were identified. Conclusion. The miR-223-3p and the miR-126-3p are promising independent predictors of thrombotic events and can be used for ischemic risk stratification after AMI.

Background: Early coronary revascularization and medical therapy advancement improve the survival of patients (pts) with acute myocardial infarction (AMI). However, survivors of AMI are at heightened risk of developing heart failure (HF) and there is a paucity of information regarding this issue in Asian countries. This study described the temporal trends in the incidence of HF after the first AMI and the predicting factors of HF development in Taiwan. Methods: We conducted a nationwide population-based cohort study by using 1999 to 2009 National Health Insurance Research Database. Pts aged≧18 years, with no history of HF, who hospitalized with a first AMI between January 2002 and December 2008 were identified and followed up for one year. The primary outcome was HF. We evaluated the incidence of HF during the index hospitalization, 30 days, 6 months, and one year after the discharge. The predicting factors of HF were identified by Cox proportional hazard model. Results: Overall, 42,011 first AMI pts (mean age 64.4 ± 13.8 years; male 75.0%) from 2002 to 2008 were identified. The HF incidence during the index hospitalization was 14.8%. After exclusion of HF during the hospitalization, the overall HF prevalence at 30 days, 6 months, and 1 year was 9.6%, 14.2%, and 16.8%, respectively. The HF prevalence at 1 year declined from 17.9% to 14.9% (p<0.05) from 2002 to 2008. The independent predicting factors of HF after the first AMI were elder age (≧65 years) (adjusted HR 1.81, 95% CI 1.51-2.18), diabetes mellitus (adjusted HR 1.30, 95% CI 1.21-1.41), chronic kidney disease (adjusted HR 1.41, 95% CI 1.20-1.65), use of loop diuretics within 30 days after the discharge (adjusted HR 2.21, 95% CI 2.00-2.43), and recurrent AMI (adjusted HR 2.43, 2.16-2.74). Conclusions: Survivors of AMI without prior HF remain at risk of developing HF in Taiwan and most episodes occur within 6 months after AMI. Five important clinical factors of HF were identified that may help us for risk stratification.
