The calcium paradox induced massive structural damage to the sarcolemma and gap junctions. Treatment of these hearts with diltiazem, a calcium channel blocking agent, significantly prevented cell separation and rupture, gap junction alterations, and preserved tissue high energy phosphate content. It is suggested that the calcium paradoxical injury may be prevented with calcium channel blocking agents by maintaining the structural integrity of junctional sarcolemma and its components.
