Introduction. Platelet-derived microparticles (PDMPs) measurement adds prognostic implication for ST-elevation acute myocardial infarction (STEMI). The long-term implication of PDMPs in STEMI needs to be corroborated. Methods. The research design was a cohort study. Subjects were STEMI patients and were enrolled consecutively. The PDMPs were defined as microparticles bearing CD41(+) and CD62P(+) markers detected with flow cytometry. The PDMPs were measured on hospital admission and 30 days after discharge. The outcomes were major adverse cardiac events (MACE), i.e., a composite of cardiac death, heart failure, cardiogenic shock, reinfarction, and resuscitated ventricular arrhythmia, occurring from hospitalization until 1 year after discharge. Results. We enrolled 101 subjects with STEMI. During hospitalization, 17 subjects (16.8%) developed MACE. The PDMPs were not different between subjects with MACE and those without (median (IQR): 3305.0/μL (2370.0–14690.5/μL) vs. 4452.0/μL (2024.3–14396.8/μL), p=0.874). Forty-five subjects had increased PDMPs in 30 days after discharge as compared with on-admission measurement. Subjects with increased PDMPs had significantly higher 30-day MACE as compared to subjects with decreased PDMPs 17 (37.8%) vs. 6 (16.7%, p=0.036). There was a trend toward higher MACE in subjects with increased PDMPs as compared to those with decreased PDMPs in 90 days after discharge (48.9% vs. 30.6%, p=0.095) and 1 year after discharge (48.9% vs. 36.1%, p=0.249). Conclusion. The PDMPs level was increased from the day of admission to 30 days after discharge in patients with STEMI. The persistent increase in the PDMPs level in 30 days after the STEMI event was associated with the 30-day postdischarge MACE and trended toward increased MACE during the 90-day and 1-year follow-up.

Background: Hypertrophic cardiomyopathy is associated with poor prognosis. In our previous study, it has been reported that patients with acute myocardial infarction and hypertrophic cardiomyopathy exhibited worse long-term outcomes than those with acute myocardial infarction without hypertrophic cardiomyopathy and those with hypertrophic cardiomyopathy without acute myocardial infarction. In this article, we aimed to assess the impact of body mass index on the long-term outcomes of hypertrophic cardiomyopathy patients with acute myocardial infarction. Methods: Seventy-eight consecutive patients with hypertrophic cardiomyopathy and acute myocardial infarction were included. Obesity was defined as body mass index ⩾28 kg/m2 adapted to Chinese. The long-term endpoints were major adverse cardiac events and secondary endpoints, which included re-hospitalization, recurrent angina, thrombosis, bleeding, heart failure, and arrhythmias. Results: There were no differences in observed in-hospital mortality or 5-year mortality between the two groups of hypertrophic cardiomyopathy and acute myocardial infarction patients divided by body mass index. However, significantly increased incidence of re-percutaneous coronary intervention and stroke was observed in the obese group (re-percutaneous coronary intervention: 0.0% vs. 21.4%, p = 0.007; stroke: 5.6% vs. 28.6%, p = 0.042). The 5-year outcomes of major adverse cardiac events were inferior in the obese group (log-rank p = 0.020). Conclusion: Acute myocardial infarction and hypertrophic cardiomyopathy patients who were obese exhibited worse long-term outcomes than those without obesity.

Hypertrophic cardiomyopathy (HCM) is associated with poor prognosis. It has been reported that there is no difference in in-hospital mortality after acute myocardial infarction (AMI) between patients with and without HCM. However, whether there are differences in long-term outcomes after AMI between patients with and without HCM remains unclear. In this study, we analyzed the clinical profiles of 78 consecutive patients with HCM and AMI (HCM and AMI group), 78 sex- and age-matched patients with AMI and without HCM (AMI group), and 78 sex- and age-matched patients with HCM and without AMI (HCM group). The study end points were major adverse cardiac events (MACEs) and secondary end points. During the follow-up period of 4.8 ± 3.6 years, MACEs occurred in 19 (27.9) patients in the HCM and AMI group, in 11 (16.7%) patients in the AMI group, and in 8 (12.3%) patients in the HCM group. The long-term outcomes of the HCM and AMI group were inferior to that of the other 2 groups (log-rank P = .030 for MACEs, log-rank P = .032 for secondary end points). In conclusion, patients with AMI with HCM exhibited worse long-term outcomes than did patients with AMI without HCM and patients with HCM without AMI.

Abstract Background/objectives Pericoronary adipose tissue inflammation might lead to the development and destabilization of coronary plaques in prediabetic patients. Here, we evaluated inflammation and leptin to adiponectin ratio in pericoronary fat from patients subjected to coronary artery bypass grafting (CABG) for acute myocardial infarction (AMI). Furthermore, we compared the 12-month prognosis of prediabetic patients compared to normoglycemic patients (NG). Finally, the effect of metformin therapy on pericoronary fat inflammation and 12-months prognosis in AMI-prediabetic patients was also evaluated. Methods An observational prospective study was conducted on patients with first AMI referred for CABG. Participants were divided in prediabetic and NG-patients. Prediabetic patients were divided in two groups; never-metformin-users and current-metformin-users receiving metformin therapy for almost 6 months before CABG. During the by-pass procedure on epicardial coronary portion, the pericoronary fat was removed from the surrounding stenosis area. The primary endpoints were the assessments of Major-Adverse-Cardiac-Events (MACE) at 12-month follow-up. Moreover, inflammatory tone was evaluated by measuring pericoronary fat levels of tumor necrosis factor-α (TNF-α), sirtuin 6 (SIRT6), and leptin to adiponectin ratio. Finally, inflammatory tone was correlated to the MACE during the 12-months follow-up. Results The MACE was 9.1% in all prediabetic patients and 3% in NG-patients. In prediabetic patients, current-metformin-users presented a significantly lower rate of MACE compared to prediabetic patients never-metformin-users. In addition, prediabetic patients showed higher inflammatory tone and leptin to adiponectin ratio in pericoronary fat compared to NG-patients (P < 0.001). Prediabetic never-metformin-users showed higher inflammatory tone and leptin to adiponectin ratio in pericoronary fat compared to current-metformin-users (P < 0.001). Remarkably, inflammatory tone and leptin to adiponectin ratio was significantly related to the MACE during the 12-months follow-up. Conclusion Prediabetes increase inflammatory burden in pericoronary adipose tissue. Metformin by reducing inflammatory tone and leptin to adiponectin ratio in pericoronary fat may improve prognosis in prediabetic patients with AMI.

Background: Stress hyperglycemia is a common phenomenon in patients presenting with acute myocardial infarction (MI). We aim to evaluate the association of stress hyperglycemia at the time of hospital presentation and adverse cardiac events in myocardial infarction during the course of hospital stay. Methods: Subjects with age ≥18 years with acute MI were recruited on hospital admission and categorized based on admission blood glucose (<180 and ≥180 mg/dl, 50 patients in each group). Both groups were compared for clinical outcomes, adverse cardiac events and mortality. We also compared the adverse cardiac outcomes based on HbA1c levels (<6% and ≥6%). Results: Patients with high blood glucose on admission (stress hyperglycemia) had significant increased incidences of severe heart failure (Killip class 3 and 4), arrythmias, cardiogenic shock and mortality (p value = 0.001, 0.004, 0.044, and 0.008 respectively). There was no significant association between adverse cardiac events and HbA1c levels (heart failure 18.8% vs. 25%, p value = 0.609 and mortality 16.7% vs. 17.3%, p value = 0.856). Conclusions: Stress hyperglycemia is significantly associated with adverse clinical outcomes in patients with MI irrespective of previous diabetic history or glycemic control. Clinicians should be vigilant for admission blood glucose while treating MI patients.
