Role of serum sodium in severity and complications of myocardial infarction

Abstract

Background: A myocardial infarction (MI), sometimes referred to as a heart attack, happens
when blood flow is cut off to a portion of the heart for an extended period of time, causing
damage or even death to a portion of the heart muscle. The present study evaluated role of
serum sodium in severity and complications of myocardial infarction
Materials & Methods: 86 patients of acute myocardial infarction of both genders were
divided into two groups. Group I had a mean serum sodium level >135 mmol/l and group II
had a mean serum sodium level ≤135 mmol/lbased on the mean serum sodium value.
Results: In group I, 2 cases had RVF in AWMI and 2 had biventricular failure in AWMI. 1
case each in IWMI had RVF and biventricular failure. In group II, 5 RVF included AWMI, 7
IWMI and 2 biventricular failures in AWMI and 7 RVF and 1 biventricular failure in IWMI.
The difference was significant (P< 0.05). There were 20 patients in group I and 18 patients in
group II, class II had 14 patients in group I and 13 patients in group II, class III had 6 patients
in group I and 7 patients in group II and class IV had 3 patients in group I and 5 patients in
group II according to Killip’s classification. There were 2 mortalities of male and 1 female in
group I and 6 males and 2 females in group II. The difference was significant (P< 0.05).
Conclusion: The severity, after effects, and prognosis of myocardial infarction are all
favorably connected with serum sodium levels. As a result, monitoring blood sodium levels
may help with the rapid assessment of myocardial infarction severity and the prognosis of
consequences for early intervention.
