Abstract/OtherAbstract:
BACKGROUND: Subjects with frequent ventricular premature complexes (VPC) and no apparent heart disease make a heterogenic group with regard to prognosis. Some biomarkers have recently proved useful in risk stratification in different heart diseases. We examined prognostic impact of NT-Pro-brain natriuretic peptide (NT-Pro BNP), and C-reactive protein (CRP) in relation to frequent VPC in subjects with no apparent heart disease. METHODS: Six hundred seventy-eight healthy subjects between 55 and 75 years of age with no history of cardiovascular disease were included in the study. All were tested with fasting laboratory testing and 48-hour ambulatory ECG monitoring. Frequent VPC was defined as VPC > or =30/hour. RESULTS: In 56 subjects (8%) with frequent VPC the prognosis was much poorer compared to those without frequent VPC (Hazard ratio and 95% CI: 2.3;1.2-4.4, P = 0.01), after adjustment for conventional risk factors. In subjects with frequent VPC increased levels of CRP (above 2.5 microg/mL) was the only factor among the tested biomarkers, which was associated with a poor prognosis. Taking subjects without frequent VPC as reference, the hazard ratio and 95% CI for subjects with frequent VPC and increased CRP was 3.6;1.8-7.1, P = 0.0004, and for those with frequent VPC and normal CRP 0.8;0.2-3.5, P = 0.83, after correction for conventional risk factors. CONCLUSIONS: Among middle-aged and elderly subjects with no apparent heart disease and frequent VPCs, a CRP value > or =2.5 microg/mL is associated with a significantly higher risk of death and acute myocardial infarction. These subjects deserve primary prevention measures and further work up for structural heart disease.
