the influence of nicorandil , a potent antianginal drug , on cellular calcium in vascular smooth muscle cells ( vsmc ) was investigated by studying its effects on the cytosolic free calcium concentration ( [ ca2+ ] i ) and calcium-stimulated magnesium-dependent atpase [ ( ca2+ + mg2+ ) -atpase ] in the cells .
