High Serum Cyclophilin C levels as a risk factor marker for Coronary Artery Disease

Cyclophilins (Cyps) are ubiquitous proteins that belong to the immunophilins family consistently associated with inflammatory and cardiovascular diseases. While levels of CypA have been extensively studied, less data are available for other Cyps. The purpose of this case-control study was to determine the relationship of Cyps (A, B, C and D) with coronary artery disease (CAD) and eight inflammation markers. Serum levels of Cyps, interleukins and metalloproteinases were measured in serum collected from 84 subjects. Participants were divided into two sub-groups based on CAD diagnosis: 40 CAD patients and 44 control volunteers. Serum levels of CypA, CypB and CypC, IL-1β and IL-6 were significantly higher in CAD patients. Bivariate correlation analysis revealed a significant positive correlation between Cyps and several blood and biochemical parameters. When the ability of Cyps levels for CAD diagnosis was evaluated, higher sensitivity and selectivity values were obtained with CypC (c-statistic 0.891, p < 0.001) indicating that it is a good marker of CAD disease, while less conclusive results were obtained with CypA (c-statistic 0.748, p < 0.001) and CypB (c-statistic 0.655, p < 0.014). In addition, significant correlations of traditional CAD risk factors and CypC were observed. In summary, high levels of CypC are a risk factor for CAD and therefore it can be proposed as a new biomarker for this disease.This work could not have been done without the invaluable collaboration of the staff at the Servicio Vixilancia da Saude from Universidad de Santiago de Compostela (Andrea Vidal Dopazo) and at the Cardiology Department, Hospital Universitario Lucus Augusti (Maria Jesús Basanta-Castro, Maria del Carmen Cabarcos Leal, Clara Jimenez-Serrano, Leonor Ortega- Fernández, Maria Jesus Palacios Pool, Sofía Seco-Aldegunde).

Cyclophilins in Ischemic Heart Disease: Differences Between Acute and Chronic Coronary Artery Disease Patients

Background: Cyclophilins (Cyps) are a family of peptidyl-prolyl cis/trans isomerases consistently involved in cardiovascular diseases through the inflammation pathway. This study aims to investigate the serum levels of Cyps (CypA, CypB, CypC and CypD) in patients with coronary artery disease (CAD) and the correlation with clinical characteristics and inflammation parameters. Methods: We developed an observational prospective study with a total of 125 subjects: 40 patients with acute CAD, 40 patients with chronic CAD and 45 control volunteers, in whom serum levels of Cyps (CypA, CypB, CypC and CypD), interleukins and metalloproteinases were measured. Results: CypA levels increased significantly in CAD patients compared with control subjects, but no differences were noted between acute CAD (7.80 +/- 1.30 ng/mL) and chronic CAD (5.52 +/- 0.76 ng/mL) patients (P = 0.13). No differences in CypB and CypD levels were showed between CAD patients and controls and between acute CAD and chronic CAD patients. In relation with CypC, the levels in CAD patients were significantly higher compared to controls (32.42 +/- 3.71 pg/mL vs. 9.38 +/- 1.51 pg/mL, P 17.5 pg/mL cut-off point, and it was significantly associated with older age, hypertension, dyslipidemia and more extensive CAD in acute and chronic CAD groups. Conclusions: CypA and CypC levels are increased in CAD patients. High CypC serum levels could be a novel biomarker in CAD patients correlating with a more severe disease

Programa Gallego de Atenci?n al Infarto Agudo de Miocardio. Protocolo de actuaci?n para pacientes con s?ndrome coronario agudo con elevaci?n del segmento ST en Galicia

A enfermidade coronaria sup?n un importante problema de sa?de p?blica debido ? s?a incidencia crecente e a que constit?e a principal causa de morte no mundo. no ?mbito da Comunidade Aut?noma de Galicia, p?xose en marcha en maio de 2005 o Programa Galego de Atenci?n ao Infarto Agudo de Miocardio (PROGALIAM). Este programa foi un dos primeiros en implantarse en Espa?a (s? por detr?s dos de Murcia e Navarra). Debido ao tempo transcorrido, viuse necesario adaptar o Progaliam do ano 2005 ?s novas e actuais evidencias, e ?s actuais recomendaci?ns das Gu?as de Pr?ctica Cl?nica. ? por iso, que na Direcci?n Xeral de Asistencia Sanitaria, constitu?use un grupo de traballo formado por cardi?logos intervencionistas das 7 ?reas sanitarias, as? como profesionais m?dicos de Atenci?n Primaria e Urxencias.La enfermedad coronaria supone un importante problema de salud p?blica debido a su incidente creciente y la que constituye la principal causa de muerte en el mundo. en el ?mbito de la Comunidad Aut?noma de Galicia, se puso en marcha en mayo de 2005 el Programa Gallego de Atenci?n al Infarto Agudo de Miocardio (PROGALIAM).
