Abstract
Background:
High-sensitivity C-reactive protein (hsCRP) is an important biomarker of risk for coronary heart disease morbidity and mortality. We investigated the influence of short-term cardiac rehabilitation (CR) after acute myocardial infarction (AMI) on values of hsCRP and classical risk factors, including metabolic syndrome.
Methods:
hsCRP and classical risk factors were measured before and after completed 2-week CR program in 30 men after AMI. The comparison group comprised 30 age-balanced healthy men, with no risk factors for coronary heart disease.
Results:
As expected, in comparison to healthy individuals, patients had higher values of hsCRP; furthermore, smokers had significantly higher hsCRP values than nonsmokers. Patients had more expressed markers of metabolic syndrome and due to pharmacological therapy lower blood pressure, total cholesterol and low-density lipoprotein cholesterol (LDL-C). After CR was completed, a significant drop in hsCRP (P=0.006) and improvement of metabolic syndrome parameters (lower body mass index, blood pressure, LDL-C, triglycerides) was observed in nonsmokers, whereas no such changes occurred in smokers.
Conclusions:
Our study revealed that hsCRP and metabolic syndrome parameters can be substantially reduced by a 2-week CR program; however, this effect is present only in nonsmokers. Thus, all patients entering the CR program after AMI should be advised to quit smoking before entering the program to achieve optimal benefits.
