    Influencia del grado de la severidad de la estenosis, del diámetro del vaso y del modelo de stent en el fenómeno del retroceso elástico en angioplastia coronaria. Evaluación angiográfica

    Purpose: Stent recoil following stent deployment is still a very important outcome predictor after angiographic intervention. The aim of this study is to assess the influence of device model, angiographic characteristics of the lesion and vessel size on stent recoil. Methods: 61 consecutive patients were included in the study. 81 stents were successfully deployed. Maximal balloon diameter at peak pressure and maximal lumen diameter after stenting were measured by QCA (quantitative coronary angiography) Results: There were no significant differences regarding either the model of device or length, symmetry or severity of the lesion. There were significant differences regarding the vessel size. Stent recoil was greater in small vessels (<2,75 mm). Discussion: This finding is a paradox. The small size of the vessel has been always identified as an independent risk factor for the development of stenosis. The use of stents in small vessels remains controversial.

    Cardiovascular diseases, especially coronary heart disease, are the leading cause of mortality in Spain and western countries. The prevention of complications is based on a cardiovascular risk stratification that is based on the presence of classical cardiovascular risk factors. There are many scales for cardiovascular risk stratification that classify subjects into low, intermediate or high risk. Despite the fact that the impact and treatment of risk factors are well known, their control remains poor. Obesity, diabetes, and hypertension seems also seem to be increasing trends due to the changes in lifestyles and nutritional habits of our communities. In recent decades some new, or emerging, cardiovascular risk factors have been identified that can improve the stratification of cardiovascular risk: C-reactive protein, homocysteine, and lipoprotein a. The metabolic syndrome is an association of cardiovascular risk factors that cluster in the same subject because they share a physiopathologic link: insulin resistance. Its presence is related to most cardiovascular risk factors, classical or emerging, especially obesity, hypertension, and C-reactive protein. On the other hand, detection of subclinical or incipient atherosclerosis, especially with the measurement of intima-media thickness, offers indirect information closely related to coronary atherosclerosis that improves the stratification of subjects at intermediate risk.
