ABSTRACT
Background: The concentration of BNP rises quickly in the first 24 hours after the acute myocardial infarction. The relationship between this increase and the appearance of arrhythmias is ignored.
Objective: To demonstrate that the high concentration of BNP is translated in more bias to mortal and bad presaged arrhythmias.
Results: A prospective study with 60 patients divided in 2 groups those who presented arrhythmias 41 subjects 68.33% and those who did not present arrhythmias patient 19 31.66 %. NYHA I [n (%)]: 18 (94) vs 12 (29.3), p ‹ 0.001; NYHA the II: 1 (5.3) vs 15 (36.6), p = 0.011; NYHA the III: 0 (0) vs 13 (31.7), p = 0.003; low risk unstable angina: 8 (42.1) vs 4 (9.8), p = 0.006; previous AMI: 0 (0) vs 8 (19.5), p = 0.037; troponin I › 0.5: 26.3 vs 34 (82.9), p ‹ 0.001; FEVI ‹ 40%: 0 (0) vs 23 (63.4), p ‹ 0.001, duration of the chest pain (min.), Md (25deg;-75deg;): 120 (30-240) vs 240 (120-720), p = 0.003; treatment for ICC: 0 (0) vs 8 (19.5), p = 0.039; BNP (pg/mL), Md (25deg;-75deg;): 49 (41-66) vs 444 (196-894), p ‹ 0.001.
Conclusions: The concentration of BNP in patients with acute coronary syndrome provides information about the heart suffering for isquemia or stress of the wall. That allows to infer acute complications of arrhythmic type in the acute phase, since a relationship exists between the high concentrations of BNP and the appearance of arrhythmias of bad presage.
