Association between inflammatory gene polymorphisms and the risk of myocardial infarction

Allele and genotype frequency distributions of polymorphism rs2076059 (3832T>C) within the SELE gene, rs6131 (S290N), within the SELP gene, rs1131498 (F206L), within the SELL gene, rs5498 (K469E) within the ICAM1 gene, rs35569394 (?2549(18)I/D) within the VEGFA gene, and rs1024611 (?2518A>G) within the CCL2 gene were examined in a group of patients after myocardial infarction (MI)(280 individuals) and in a control group (312 individuals). An implementation of the Markov chain and Monte-Carlo method (APSampler) revealed the allele combinations associated with decreased and increased risk of MI. Among these, the most important allele combinations were SELE*C + SELP*S + CCL2*A (FDR = 0.0005; OR = 0.42), SELP*S + CCL2*A (FDR = 0.0009; OR = 0.36), SELL*F + VEGFA*I + CCL2*G/G (FDR = 0.0009; OR = 4.17), VEGFA*I + CCL2*G/G (FDR = 0.0009; OR = 3.76), SELE*C + CCL2*A (FDR = 0.0023; OR = 0.47), and SELL*F + CCL2*G/G (FDR = 0.003; OR = 3.15).     

Hemodynamic monitoring in acute myocardial infarction.

The main cause of in-hospital death in patients with acute myocardial infarction is the "power failure syndrome". Hemodynamic monitoring provides precise and current data on the filling and output status of the left ventricle and, when indicated, the right ventricle. The information obtained is used to determine the hemodynamic status more precisely than is possible from conventional clinical assessment. It permits categorization of patients by hemodynamic status; the hemodynamic subset classification of Forrester, Diamond and Swan is a powerful tool in guiding therapy and establishing prognosis in individual patients. In addition to guiding the initiation of therapy, hemodynamic monitoring is useful in the continuing assessment of potent and complex treatment. This therapy is directed at resolving hemodynamic derangements without unfavourably altering the myocardial oxygen supply-demand relationship. Specific clinical indications for hemodynamic monitoring may include confusing or complicated clinical situations in which diagnostic problems exist, complicating mechanical derangements, severe congestive heart failure, cardiogenic shock and clinical research in acute myocardial infarction.
