| pubmed-article:3530767 | pubmed:abstractText | An overview is provided of current thinking regarding the origin(s) of atherosclerosis on the basis of clinical evidence, experimental models and pharmacological investigations with calcium antagonists. Because this group of drugs inhibits the influx of Ca2+ into the smooth muscle cell of the cardiovascular wall, it has been argued that when endothelial damage is anticipated or has occurred, the 'protective' action of calcium antagonists might avoid, delay or even help to repair the calcium overload seen with cell membrane damage. In the real world the situation must be far more complex as will become evident but as a concept the avoidance of Ca2+ overloading is enticing. In fact, based on circumstantial evidence, a major clinical trial is currently in progress in which the long term effect of nifedipine on coronary atherosclerosis is being evaluated in a double blind randomized fashion. The end-point of this study lies in the reduction of the severity and number of coronary artery lesions. Although not yet completed, the design and goals of that study are provided. | lld:pubmed |
