Objective: Our primary objective was to analyze the association between DM and precordial pain at hospital arrival. Secondary analyses evaluated the association between hyperglycemia and precordial pain at presentation, and the subgroup of patients presenting within 6 hours of symptom onset. Methods: We analyzed a prospectively designed registry of 3,544 patients with ACS admitted to a Coronary Care Unit of a tertiary hospital. We developed multivariable models to adjust for potential confounders. Results: Patients with precordial pain were less likely to have DM (30.3%) than those without pain (34.0%; unadjusted p = 0.029), but this difference was not significant after multivariable adjustment, for the global population (p = 0.84), and for subset of patients that presented within 6 hours from symptom onset (p = 0.51). In contrast, precordial pain was more likely among patients with hyperglycemia (41.2% vs 37.0% without hyperglycemia, p = 0.035) in the overall population and also among those who presented within 6 hours (41.6% vs. 32.3%, p = 0.001). Adjusted models showed an independent association between hyperglycemia and pain at presentation, especially among patients who presented within 6 hours (OR = 1.41, p = 0.008). Conclusion: In this non-selected ACS population, there was no correlation between DM and hospital presentation without precordial pain. Moreover, hyperglycemia correlated significantly with pain at presentation, especially in the population that arrived within 6 hours from symptom onset.
- Relation of High Lipoprotein (a) Concentrations to Platelet Reactivity in Individuals with and Without Coronary Artery Disease(2020) SALSOSO, Rocio; DALCOQUIO, Talia F.; FURTADO, Remo H. M.; FRANCI, Andre; BARBOSA, Carlos J. D. G.; GENESTRETI, Paulo R. R.; STRUNZ, Celia M. C.; LIMA, Viviane; BARACIOLI, Luciano M.; GIUGLIANO, Robert P.; GOODMAN, Shaun G.; GURBEL, Paul A.; MARANHAO, Raul C.; NICOLAU, Jose C.Introduction Lipoprotein (a) [Lp(a)] is a risk factor for coronary artery disease (CAD). To the best of our knowledge, this is the first study addressing the relationship between Lp(a) and platelet reactivity in primary and secondary prevention. Methods Lp(a) was evaluated in 396 individuals with (82.3%) and without (17.7%) obstructive CAD. The population was divided into two groups according to Lp(a) concentrations with a cutoff value of 50 mg/dL. The primary objective was to evaluate the association between Lp(a) and adenosine diphosphate (ADP)-induced platelet reactivity using the VerifyNow (TM) P2Y(12)assay. Platelet reactivity was also induced by arachidonic acid and collagen-epinephrine (C-EPI) and assessed by Multiplate (TM), platelet function analyzer (TM) 100 (PFA-100), and light transmission aggregometry (LTA) assays. Secondary objectives included the assessment of the primary endpoint in individuals with or without CAD. Results Overall, 294 (74.2%) individuals had Lp(a) < 50 mg/dL [median (IQR) 13.2 (5.8-27.9) mg/dL] and 102 (25.8%) had Lp(a) >= 50 mg/dL [82.5 (67.6-114.5) mg/dL],P < 0.001. Univariate analysis in the entire population revealed no differences in ADP-induced platelet reactivity between individuals with Lp(a) >= 50 mg/dL (249.4 +/- 43.8 PRU) versus Lp(a) < 50 mg/dL (243.1 +/- 52.2 PRU),P = 0.277. Similar findings were present in individuals with (P = 0.228) and without (P = 0.669) CAD, and regardless of the agonist used or method of analysis (allP > 0.05). Finally, multivariable analysis did not show a significant association between ADP-induced platelet reactivity and Lp(a) >= 50 mg/dL [adjusted OR = 1.00 [(95% CI 0.99-1.01),P = 0.590]. Conclusion In individuals with or without CAD, Lp(a) >= 50 mg/dL was not associated with higher platelet reactivity.

- Platelet function, coagulation and fibrinolysis in patients with previous coronary and cerebrovascular ischemic events(2019) BARBOSA, Carlos Jose Dornas Goncalves; BARREIROS, Renata de Souza; FRANCI, Andre; ARANTES, Flavia Bittar Brito; FURTADO, Remo Holanda de Mendonca; STRUNZ, Celia Maria Cassaro; ROCHA, Tania Rubia Flores da; BARACIOLI, Luciano Moreira; RAMIRES, Jose Antonio Franchini; KALIL-FILHO, Roberto; NICOLAU, Jose CarlosOBJECTIVES: Ischemic stroke (IS) or transient ischemic attack (TIA) history is present in 4-17% of patients with coronary artery disease (CAD). This subgroup of patients is at high risk for both ischemic and bleeding events. The aim of this study was to determine the role of platelet aggregability, coagulation and endogenous fibrinolysis in patients with CAD and previous IS or TIA. METHODS: A prospective case-control study that included 140 stable CAD patients divided into two groups: the CASE group (those with a previous IS/TIA, n=70) and the CONTROL group (those without a previous IS/TIA, n=70). Platelet aggregability (VerifyNow Aspirin (R) and VerifyNow P2Y12 (R)), coagulation (fibrinogen and thromboelastography by Reorox (R)) and endogenous fibrinolysis (D dimer and plasminogen activator inhibitor-1) were evaluated. RESULTS: Patients in the CASE group presented significantly higher systolic blood pressure levels (135.84 +/- 16.09 vs 123.68 +/- 16.11, p <0.01), significantly more previous CABG (25.71% vs 10%, p=0.015) and significantly higher calcium channel blocker usage (42.86% vs 24.29%, p=0.02) than those in the control group. In the adjusted models, low triglyceride values, low hemoglobin values and higher systolic blood pressure were significantly associated with previous IS/TIA (CASE group). Most importantly, platelet aggregability, coagulation and fibrinolysis tests were not independently associated with previous cerebrovascular ischemic events (CASE group). CONCLUSION: Platelet aggregability, coagulation and endogenous fibrinolysis showed similar results among CAD patients with and without previous IS/TIA. Therefore, it remains necessary to identify other targets to explain the higher bleeding risk presented by these patients.
