Abstract:
Objective To determine the prevalence and prognostic implication of hypocalcemia in the set-ring of acute myocardial infarction. Method The study consisted of 1274 consecutive patients presenting with a-cute myocardial infarction. Plasma calcium concentrations were obtained on the 1st day, 2nd day, 3rd day after admission. According to the plasma calcium concentrations, 1274 patients with AMI were designed into four groups:group A (Ca2+≥2.20 mmol/L),gronp B (2.00～2.19 mmol/L), group C (1.90～1.99 mmol/L),group D (Ca2<1.9 mmol/L). Echocardiographic examination was performed on day 2 or 3 of hospitalization.Results There were 606 patients (47.6%) having hypocalcemia, defined as a plasma calcium level <2.2mmol/L. Among them, there were 476 patients(37.4%) in group B(2.00～2.19 mmol/L), 73 patients(5.7 %)in group C (1.90～1.99 hanoi/L) and 45 patients(3.5%)in group D(Ca2+< 1.90 retooL/L). The mortality of group A was 2.5 %, on the contrary, the mortality of the other groups was 7.8 %, 20.5 %, 17.8 %. The difference was significant. In multivariate logistic regression analysis, hypocalcemia was independently associated with 30-day mortality. Conclusions Hypocalcemia in patients with acute myocardial infarction is an independent predictor of 30-day mortality.
