Abstract

To evaluate the prognostic significance of hyponatremia in patients with AMI. The study population consisted of 670 patients with AMI in coronary care unit in our hospital from January 2003 to December 2004. The patients were designed into three groups according to serum sodium concentration within twenty four to forty eight hours following the onset of AMI: Group A. Na(+) > or = 135 mmol/L; Group B. Na(+) 120-135 mmol/L; Group C. Na(+) < or = 120 mmol/L. The data of myocardial enzymes, myocardial infarction size, heart function and inhospital mortality were analyzed retrospectively. 1. The inhospital mortality of each group: group A was 7.6% (17/225), group B was 8.1% (34/421), group C was 33.3% (8/24). The difference between group C and group B or group A was significant. The P value was little than 0.05. 2. Activities of serum creatine phosphatase kinase and serum creatine phosphatase kinase isoenzymes and myocardial infarction sizes in each group were different (P < 0.05). 3. 59 cases of all died and 611 cases of all recovered in duration of hospital stay. Serum sodium concentrations of the recovered group were (133.00 +/- 5.25) mmol/L, and that of the died group were (122.00 +/- 7.25) mmol/L (P < 0.01). 4. In a multivariat...Continue Reading
