PON1 status is influenced by oxidative stress and inflammation in coronary heart disease patients

Our CHD patients were in a state of oxidative stress, which was most evident in the RR phenotype group. The QQ phenotype group is associated with the lowest oxidative stress status level and also with a better capacity for anti-oxidative protection. Oxidative stress in CHD patients is maintained by systemic low-grade inflammation, which results in PON1 enzymatic activity exhaustion. Therefore, deeper investigation of an effective anti-oxidative and anti-inflammatory therapy should be necessary in order to increase anti-oxidative potency and improve PON1 status of CHD patients.
