RESUMEN
BACKGROUND: The association between symptom interpretation and prognosis has not been investigated well among patients with acute coronary syndrome (ACS). As such, the present study evaluated the effect of heart disease awareness among patients with ACS on in-hospital mortality. METHODSâANDâRESULTS: We performed a post hoc analysis of 1,979 consecutive patients with ASC with confirmed symptom interpretation on admission between 2014 and 2018, focusing on patient characteristics, recanalization time, and clinical outcomes. Upon admission, 1,264 patients interpreted their condition as cardiac disease, whereas 715 did not interpret their condition as cardiac disease. Although no significant difference was observed in door-to-balloon time between the 2 groups, onset-to-balloon time was significantly shorter among those who interpreted their condition as cardiac disease (254 vs. 345 min; P<0.001). Moreover, the hazard ratio (HR) for in-hospital mortality was significantly higher among those who did not interpret their condition as cardiac disease based on the Cox regression model adjusted for established risk factors (HR 1.73; 95% confidence interval 1.08-2.76; P=0.022). CONCLUSIONS: This study demonstrated that prehospital symptom interpretation was significantly associated with in-hospital clinical outcomes among patients with ACS. Moreover, the observed differences in clinical prognosis were not related to door-to-balloon time, but may be related to onset-to-balloon time.

BACKGROUND: The safety and feasibility of using 1-month dual antiplatelet therapy (DAPT) followed by P2Y12inhibitor monotherapy for patients after percutaneous coronary intervention (PCI) with thin-strut biodegradable polymer drug-eluting stents (BP-DES) in daily clinical practice remain uncertain. METHODSâANDâRESULTS: The REIWA region-wide registry is a prospective study conducted in 1 PCI center and 9 local hospitals in northern Japan. A total of 1,202 patients who successfully underwent final PCI using BP-DES (Synergy: n=400; Ultimaster: n=401; Orsiro: n=401), were enrolled in the registry, and received 1-month DAPT followed by P2Y12inhibitor (prasugrel 3.75 mg/day or clopidogrel 75 mg/day) monotherapy. The primary endpoint was a composite of cardiovascular and bleeding events at 12 months, including cardiovascular death, myocardial infarction (MI), definite stent thrombosis (ST), ischemic or hemorrhagic stroke, and Thrombolysis in Myocardial Infarction (TIMI) major or minor bleeding. Based on the results of a previous study, we set the performance goal at 5.0%. Over the 1-year follow-up, the primary endpoint occurred in 3.08% of patients, which was lower than the predefined performance goal (Pnon-inferiority<0.0001). Notably, definite ST occurred in only 1 patient (0.08%) within 1 year (at 258 days). No differences were observed in the primary endpoint between stent types. CONCLUSIONS: The REIWA region-wide registry suggests that 1-month DAPT followed by P2Y12inhibitor monotherapy is safe and feasible for Japanese patients with BP-DES.

Objective We aimed to reveal detailed on-treatment lipid profiles, lipid-related surrogate markers, and factors predicting failure to achieve the guideline-recommended lipid management goal following guideline-recommended statin treatment in Japanese patients with acute myocardial infarction (AMI). Methods and Results Sixty AMI patients who underwent coronary intervention and had received rosuvastatin 10 mg/day since the start of their hospitalization were assessed for on-treatment lipid-related profiles, including high-sensitivity C-reactive protein, small dense low-density lipoprotein cholesterol (sd LDL-C), and lipoprotein (a), at the 12-week follow-up. Patients who failed to achieve the guideline-recommended lipid management at 12 weeks were defined as the "unachieved group." Univariate and multivariate logistic regression analyses were performed to evaluate the predictors of inclusion in the unachieved group after high-dose statin treatment. Despite the use of high-dose rosuvastatin, 61.7% of the enrolled AMI patients were included in the unachieved group. In addition, the unachieved group had higher sd LDL-C and lipoprotein (a) levels than the achieved group. Logistic regression analyses demonstrated that low baseline high-density lipoprotein cholesterol (HDL-C) levels and the absence of diabetes were predictors of inclusion in the unachieved group. Conclusion More than half of the Japanese AMI patients treated with rosuvastatin 10 mg/day did not achieve the guideline-recommended goal of lipid management and still had lipid-related residual risk at 12 weeks. Particular attention should be paid to patients with low baseline HDL-C levels and those without diabetes with regard to their on-treatment lipid profiles.
