Chronic heart failure and obesity are two conditions which despite all the advances made in the recent years, still represent two of the leading causes of morbidity and mortality worldwide. Moreover, a well-known fact is that the risk of sudden cardiac death, mostly related to malignant arrhythmias is higher in apparently healthy obese individuals in comparison with lean subjects. On the other hand, obese heart failure patients bring unique challenges in the diagnosis of heart failure, having a better prognosis than their normal or underweight counterparts. Taking into account the above-mentioned existing data, there are questions regarding whether cardiac arrhythmias such as atrial fibrillation or ventricular arrhythmias in this population have certain evolutive particularities. This paper describes various mechanisms of cardiac arrhythmias found in obese heart failure patients, such as myocardial architectural changes, neurohormonal and paracrine modifications.
