Serum creatine kinase in obese subjects before and during weight reduction
Insights
Obesity does not directly increase creatine kinase (CK) levels, a marker for heart issues. Even during weight loss programs, CK values in obese patients remained stable, suggesting overweight itself doesn't elevate this cardiac risk indicator.
Area of Science:
- Cardiology
- Endocrinology
- Biochemistry
Background:
- Obesity is a significant risk factor for cardiovascular diseases.
- Creatine kinase (CK) levels are crucial in diagnosing myocardial infarction.
- Elevated CK can also result from muscle mass or tissue breakdown, complicating interpretation in obese individuals.
Purpose of the Study:
- To investigate the relationship between body weight and CK values in obese patients.
- To monitor CK level changes during a supervised weight reduction program in obese individuals.
Main Methods:
- Analysis of CK values in 120 obese patients.
- Monitoring CK levels during a weight loss intervention in a subset of 26 patients.
Main Results:
- CK values did not correlate with increased body weight in the obese cohort.
- No systematic changes in CK levels were observed during the weight loss program.
Conclusions:
- Elevated CK values in obese patients, particularly in a coronary care unit setting, cannot be solely attributed to overweight.
- Further investigation is needed to determine the causes of elevated CK in obese individuals.
Abstract:
Obese subjects are at increased risk for cardiovascular disease manifestations. The CK value is an important aid in the diagnosis of myocardial infarction, but may also be increased by factors such as muscle mass or breakdown of muscle tissue. We analysed CK values in 120 obese patients in our Obesity Unit and also monitored CK values during a weight reduction programme in 26 of these patients. CK values did not increase with body weight, and during weight loss in a diet programme no systematic CK changes were observed. We conclude that in the evaluation of an elevated CK value in a coronary care unit, such an increased value cannot be accounted for by the overweight per se.
