[Effect of verapamil on the functional status of thrombocytes in patients with ischemic heart disease]

A study of 20 anginal patients demonstrated signs of platelet hyperreactivity: increased platelet aggregation, increased mobilization of Ca2+ from platelet membranes, and increased production of malonic dialdehyde. A short-term treatment with isoptin-120 (360 mg daily) produced a considerable drop in those parameters. It is suggested that the drug's basic effect is due to the inhibition of intracellular calcium redistribution in the platelets of coronary patients.
