What is the impact of obesity on short-term and long-term outcomes after percutaneous coronary intervention?
According to the study by Gruberg et al. (2002), it has been observed that obese patients undergoing percutaneous coronary intervention have a lower risk of short-term and long-term mortality compared to non-obese patients. This phenomenon is known as the 'obesity paradox', which suggests that obesity may offer a protective effect in some cardiovascular diseases. However, it has also been noted that obese patients may be more likely to suffer from complications related to the procedure, such as restenosis or target vessel revascularization.
