Abstract

This study sought to clarify the relationship between magnesium (Mg) deficiency and coronary artery spasm provoked by pharmacologic agents in patients with a recent acute myocardial infarction (AMI). Twenty-three consecutivepatients suffering from AMI were investigated with a Mg retention test (Mg: 0.1 mmol/kg for 4h) in both the acute phase (within 1 week (3 +/-2 days) of onset) and the subacute phase (3-4 weeks (24 +/-6 days) of the onset). Early coronary arteriography was performed in all patients. Coronary stenosis in the infarct-related artery was less than 90% in all patients in the subacute phase. The spasm provocation test was performed in the subacute phase and coronary spasm was defined as transient subtotal or total occlusion in association with angina or electrocardiographic ST-segment deviation. Coronary artery spasm was provoked in only 13 of the 23 patients. Compared with the control subjects(12 patients without coronary artery disease or coronary spasm), the 24-h Mg retention was significantly higher in patients withAMI (acute phase: 78 +/- 27%, subacute phase: 66 +/- 32%, vs control: 48 +/- 12%, p<0.05). In the subacute phase, the 24-h Mg retention decreased in patients without coronary spasm (43<plus/minus>26%), but a high level of Mgretention was still observed in patients with coronary spasm (84 +/- 25%). There was no difference in the serum concentrations of Mg, calcium and phosphorus between the 2 groups on both phases. In conclusion, both Mg deficiency and provoked coronary artery spasm were noted in more than half of the Japanese patients with a recent AMI, suggesting a close association betweenMg deficiency and AMI.
