Mortalidad, riesgo cardiovascular y estado de salud actual de una cohorte de varones iniciada en el año 1968. Estudio Manresa / Mortality, cardiovascular risk, and health status in a male cohort initiated in 1968. The Manresa study

Objetivos: Analizar la mortalidad y sus causas en la cohorte Manresa de varones seguida durante 42 años; comparar el riesgo de mortalidad cardiovascular al inicio del seguimiento con la mortalidad acontecida; describir el estado de salud de los participantes al final del estudio. Métodos: Estudio observacional prospectivo. Se calculó la incidencia de mortalidad acumulada de la cohorte. La asociación de los factores de riesgo cardiovasculares (FRCV) con la mortalidad fue calculada mediante análisis de regresión logística de efectos mixtos. Se evaluó la curva ROC comparando cada ecuación predictiva con la mortalidad real. Se llevó a cabo un análisis descriptivo del estado de salud en la última encuesta del estudio. Resultados: Las defunciones fueron 457 (43%). La incidencia acumulada fue del 10,6% para las enfermedades cardiovasculares. Los factores de riesgo cardiovasculares asociados significativamente a la mortalidad cardiovascular fueron: edad, colesterol y tabaquismo. El uso de tablas para el cálculo del riesgo cardiovascular resultó ser útil, con pocas diferencias según la tabla utilizada. Entre los factores de riesgo cardiovasculares analizados en el último examen de salud, y por tanto en una población anciana, destacan la alta prevalencia de hipertensión y de actividad física regular, junto con la baja prevalencia en tabaquismo. Conclusión: La mortalidad cardiovascular se mantuvo alta, aunque ha pasado a ser la segunda causa tras las enfermedades tumorales. Se compararon en nuestro medio las predicciones de las tablas de riesgo de mortalidad cardiovascular con la mortalidad real durante más de 4 décadas, mostrándose la importancia de estimar el riesgo cardiovascular en la población adulta.(AU)

Objectives: To analyse mortality and its causes in the Manresa male cohort followed over 42 years; to compare the initial risk of cardiovascular mortality with actual mortality; and to describe the health status of the participants at the end of the study. Methods: Prospective observational study, in which an analysis of the cumulative incidence of mortality was performed. The association of cardiovascular risk factors with mortality was calculated with a logistic regression analysis of mixed effect. The risk of mortality of individuals was evaluated and compared with true cardiovascular mortality using ROC curves. At the end of the study, a descriptive analysis of CVRF and health status of participants in the last survey was performed. Results: The number of deaths was 457 (43%). Cumulative incidence for cardiovascular diseases was 10.6%. Cardiovascular risk factors significantly associated with cardiovascular mortality were age, cholesterol, and smoking. The use of risk score charts for cardiovascular mortality was found to be useful, and there were no differences between tables. In the last health screening of cardiovascular risk factors levels in an elderly population, a high prevalence was found of hypertension and of regular physical activity, together with a low prevalence of smoking. Conclusions: Cardiovascular mortality remained high, although it has become the second cause after tumoural diseases. The comparison of predictions from cardiovascular mortality risk tables with actual mortality rates in our area over more than 4 decades demonstrated the importance of assessing cardiovascular risk in the adult population.(AU)

Circulating microparticles are associated with clinical severity of persistent ST-segment elevation myocardial infarction complicated with cardiogenic shock.

BACKGROUND: Cardiogenic shock (CS) is the leading cause of death in patients admitted for acute myocardial infarction (MI). Despite the recent advances in reperfusion and medical treatment mortality remains unacceptably high. Whether cells of the blood compartment in CS-patients are activated and release microparticles (cMPs) that may be both messengers and biomarkers of cell damage is not known. We aimed to investigate the cMP subtypes and parental activated cells of ST-elevation MI (STEMI)-patients complicated by CS and that of non-CS STEMI-patients (non-CS) in order to identify a cMP signature that could aid CS patient's risk stratification. METHODS: Clinically-characterized STEMI-patients with and without CS (36/group) were included. Treatment was delivered according to guidelines and included primary percutaneous coronary intervention. cMPs were characterized by triple-labeling flow cytometry using Annexin V and cell surface-specific monoclonal antibodies. RESULTS: Increased levels of leukocyte-derived (neutrophil and granulocyte origin) and platelet-derived cMPs were detected in CS compared to non-CS patients. A signature of cMPs derived from platelets, leukocytes, and endothelium discriminated CS-patients (AUC of 0.743±0.059 [95% CI: 0.628-0.859], P<0.0001) and predicted mortality in CS (AUC of 0.869±0.06 [95% CI: 0.750-0.988], P<0.0001). In CS-patients, a higher number of platelet- and monocyte-cMPs and of tissue factor-rich cMPs associated to worse myocardial blush grade and thrombolysis in myocardial infarction flow. CONCLUSIONS: cMPs derived from proinflammatory and prothrombotic cells were found to be elevated in CS-patients. In treated as per guidelines CS patients, granulocytes and neutrophils remained activated and actively shed cMPs. These cMPs were biomarkers of adverse prognosis in CS. TRANSLATIONAL ASPECT: Increased levels of leukocyte and platelet-derived circulating microparticles (cMPs) are found in cardiogenic shock (CS) patients as compared to non-CS patients. In CS-patients, a higher number of platelet- and monocyte-cMPs and a higher number of tissue factor-rich cMPs were associated to worse myocardial reperfusion. A specific prothrombotic and proinflammatory cMPs signature in cardiogenic shock (CS) patients is a potential discriminator and survival prognostic biomarker for CS, which could aid management and improve clinical outcomes.
